Two Ancient Icons of the Neotropics

The Harpy Eagle (Harpia harpyja) and the Shihuahuaco tree (Diptheryx micrantha) are iconic species of the Neotropics that play key roles in the health of the ecosystem.

The harpy eagle is the heaviest and most powerful raptor inhabiting the canopy of rainforests. Its historic distribution ranges from southern Mexico to northeastern Argentina. While the variety in its diet suggests an opportunistic foraging behavior, it feeds mostly on arboreal mammals.

Already hard to spot in the wild due to hunting and habitat loss, the harpy eagle population has plummeted in many countries of Central America.  An obstacle to its recovery is its slow reproductive rate: the eagle generally breeds every two to three years, with a single offspring per nesting effort.

A single shihuahuaco (Diptheryx micrantha) tree might sequester a third of all carbon stored in a hectare of primary forest. PC: Gianella Espinosa – Arbio

The shihuahuaco, meanwhile, is an emergent tree of the canopy that can reach a height of over 50 meters. It is patchily distributed in South America from Colombia to Bolivia. Shihuahuaco seeds and fruits are a source of food for species such as bats, agoutis, macaws, and hawks.

The slow-growing shihuahuaco can take centuries to reach its maximum height. Though not classified as endangered, it is critically threatened by logging and deforestation. In Peru, due to its hard wood and resistance to rot, the shihuahuaco is one of the most exported timber species, both legally and illegally.

Deforestation is the two species’ common destroyer: it has decreased the availability of prey and nesting sites for the eagle, while reducing disperser populations and suitable habitat for the shihuahuaco.

In a forest, the absence of large predators is associated with decreased tree diversity. The harpy eagle helps controls the presence of herbivores and thus enables many tree species to propagate. While standing, the shihuahuaco is an ecologically important species due to its broad buttresses that give structural integrity to the forest; when it falls, it leaves large gaps, facilitating successional forest growth. Further, because of the large amount of carbon a single shihuahuaco tree can store, it is a key species to fight the effects climate change.

Because of its great size, for nesting, the harpy eagle depends on emergent trees of the canopy, one of the most important being the shihuahuaco. Locals and researchers have described the close relationship between these two species. Notably, eagle nests built on shihuahuaco branches will serve for more than one reproductive season.

At Los Amigos, we are planting over a hundred shihuahuaco seedlings. Eventually, the shihuahuaco will be a common sight here… and, with luck, so will the majestic eagle.

MAAP #98: Deforestation Hotspots In The Peruvian Amazon, 2018

Base Map. 2018 Deforestation Hotspots. Data: PNCB/MINAM, SERNANP
Base Map. 2018 Deforestation Hotspots. Data: PNCB/MINAM, SERNANP

Thanks to early warning forest loss alerts,* we are able to make an initial assessment of the 2018 deforestation hotspots in the Peruvian Amazon.

The Base Map highlights the medium (yellow) to high (red) hotspots. In this context, hotspots are the areas with the highest density of forest loss alerts.

Note that the most intense hotspots are concentrated in the southern Peruvian Amazon, particularly the Madre de Dios region. In previous years, intense hotspots were also concentrated in the central Peruvian Amazon.

Next, we focus on 5 hotspots of interest (Zooms A-E).

A. La Pampa (Madre de Dios)
B. Bahuaja Sonene National Park (surroundings) (Madre de Dios, Puno)
C. Iberia (Madre de Dios)
D. Organized Deforestation (Ucayali, Loreto)
E. Central Amazon (Ucayali, Huánuco)

*The data presented in this report is an estimate based on early warning data generated by the National Program of Forest Conservation for the Mitigation of Climate Change of the Ministry of the Environment of Peru (PNCB/MINAM). We also analyzed University of Maryland GLAD alerts, obtained from Global Forest Watch.

A. La Pampa (Madre de Dios)

Zoom A shows two important cases in the southern Peruvian Amazon (Madre de Dios region). First, gold mining deforestation south of the Interoceanic Highway in the area known as La Pampa. It is important to emphasize that the Peruvian government just started “Operation Mercury 2019” (Operación Mercurio 2019), a multi-sectoral and comprehensive mega-operation aimed at eradicating illegal mining and associated crime in La Pampa, as well as promote development in the region. Second, deforestation due to agricultural activity north of the highway. As in all the zoom maps below, pink indicates forest loss in 2018.

B. Bahuaja Sonene National Park (surroundings) (Madre de Dios, Puno)

Zoom B also shows two important cases in the southern Peruvian Amazon (regions of Madre de Dios and Puno), surrounding Bahuaja Sonone National Park. First, to the north of the park, is gold mining deforestation along the upper Malinowski River. The Peruvian protected areas agency (SERNANP) points out that they have limited the deforestation south of the river (direction towards the national park) due to their intensified patrols on that side. Second, to the south of the park, is non-mining (partly agricultural) deforestation.

C. Iberia (Madre de Dios)

Zoom C takes us to the other side of Madre de Dios, around the town of Iberia, near the border with Brazil and Bolivia. This area is experiencing extensive deforestation due to agricultural activity. There most intense deforestation is just of Iberia, where a religious community of farmers (Arca Pacahuara) is reportedly establishing large corn plantations (References 1-2). Much of the 2018 (and 2017) deforestation is occurring within forest concessions, where agriculture is not permitted.

D. Organized Deforestation (Ucayali, Loreto)

In 2018 we documented two similar cases in the central Peruvian Amazon. Both have similar forms of organized deforestation, characterized by what seems to be agricultural plots arranged along new access roads. Zoom D shows the Masisea case (left panel, zoom D1) and the Sarayaku case (right panel, zoom D2). See MAAP #92 for more information.

E. Central Amazon (Ucayali, Huánuco)

As in previous years, there was extensive deforestation in the central Peruvian Amazon (Ucayali and Huánuco regions). Zoom E shows an example: small and medium-scale deforestation surrounding a pair of large-scale oil palm plantations. Some of the recent deforestation is occurring within “Permanent Production Forests,” forestry-zoned areas where agriculture is not permitted. This area also corresponds to the proposed territorial title of the indigenous Shipibo community of Santa Clara de Uchunya (see here for more information).

Camera Traps: Colorfully Capturing Motmots

Our camera traps were set up to monitor a nest of the secretive giant armadillo (Priodontes maximus). However, during a recent recording session, a less reclusive forest friend stole the spotlight: a rufous motmot (Barypththengus martii). This curious bird belongs to the Momotidae family, which comprises a group of colorful arboreal species.

Endemic to the tropics, among birds of the region, the motmots range in size from medium to medium-large. Despite their bright plumage—a combination of greens, blues and rufous (rust-like) colors—they are hard to spot. Most of the species have a long tail, and a few have two longer feathers that have racket-like tips. In contrast with many other bird families, motmots exhibit no sexual dimorphism: males and females look much alike, though on closer inspection males tend to be larger and have longer tails.

Spotting a motmot can be challenging because they sit still for long periods. They can be observed when they sally out to catch their prey, or through the sideways movement of their tails. It has been hypothesized that the turquoise-browed motmot (Eumomota superciliosa) uses this latter movement to signify to a predator that it has awareness of its presence. Thus advised, the predator might desist from an attack, preventing an unnecessary waste of energy on both sides.

Motmots can be found in a variety of forest types, from lowland tropical forest to template forests. Some species can even adapt to man-made habitats such as plantation and gardens. Motmots take their prey from leaves, twigs or branches of trees or other vegetation, and can be seen on the ground too. Smaller species feed on insects while larger ones additionally feed on other invertebrates, small vertebrates and fruits. The larger species like the Amazonian motmot (Momotus momota) and the rufous motmot have been reported to feed on bats and on poison dart frogs, respectively, in the latter case with no apparent harm to themselves.

A rufous motmot (Barypththengus martii) inspects a burrow of the giant armadillo (Priodontes maximus).

 Most of the Momotidae have similar breeding behaviors. An exception is the tody motmot (Hylomanes momotula), which is also morphologically atypical and the most primitive species of the family. These ground-nesting birds use their feet to loosen the soil to later dig their nesting burrows. Both mates share this work and the chick rearing. Motmots are solitary nesters, but when limited suitable space is available, they may concentrate in groups. A new burrow is dug for each nesting season, often close to the previous burrow. As our camera trap and other studies have reported, the rufous motmots also use old burrows of armadillos and other mammals to nest.

Like many other Neotropical birds, the motmots are understudied, and there are much more to learn about them. Who knows which other surprises they may hold!

MAAP #97: Deforestation Surge In The Colombian Amazon, 2018 Update

The Colombian Amazon is currently experiencing a deforestation surge (see graph).

The surge started three years ago (2016) and peaked in 2017 with the highest annual deforestation on record (214,744 hectares).*

Deforestation remains high in 2018: 156,722 hectares (based on early warning alert data).* If this estimate is confirmed, it would be the second highest on record (behind just 2017).

National experts indicate that land grabbing (acaparamiento de tierras) is an increasingly dominant direct driver of deforestation.

*Data from the University of Maryland. Annual data from Hansen et al (2013) [citation below] and 2018 data from GLAD alerts.

MAAP Colombia is a collaboration between Amazon Conservation and Amazon Conservation Team., funded by the MacArthur Foundation.

We also present a Base Map that shows the 2018 deforestation hotspots. Note that the deforestation is concentrated in three departments located in the transition area between the Amazon and Andes: Guaviare, Caqueta, and Meta.

We highlight the location of three critical areas that are examined in greater detail below: 1) Llanos de Yari, 2) Chiribiquete- La Macarena, and 3) Tinigua National Park.

New Year, New Fellows! Announcing the 2019 Jonathan Franzen Fellows

Two years ago, the Los Amigos Bird Observatory opened its doors to promote avian research and conservation in one of the most biodiverse ecosystems in the world: the Amazon basin. To continue with our commitment, last year, we launched our second Franzen Fellowship call for applications, targeting students and young researchers interested in avian research. The group of promising and highly qualified candidates that applied made this a tough decision. We congratulate all the candidates, and are excited to present our 2019 Franzen Fellows!

Jessica Pisconte holds a degree in biology from the Universidad Nacional San Luis Gonzaga de Ica, Peru. Her interest in avian conservation was born in the Paracas National Reserve, after which she joined a wide range of research projects to learn about the importance of birds in coastal, mountain and Amazonian ecosystems. She is currently working as a park ranger in the Tambopata National Reserve in Peru’s Madre de Dios region. As the threats due to illegal mining increased in this region, seriously affecting the environment, Jessica was motivated to research key areas to understand its impact. Los Amigos will be her starting point to study the effects on birds of mercury from gold mining. Through this project, Jessica seeks to contribute to the conservation of and knowledge regarding birds in the Peruvian Amazon.

 

 

Lisset Goméz studied biological sciences at the Universidad Mayor de San Marcos in Lima, Peru. Her interests include ecology, reproductive biology, and conservation of bird communities, and she has been involved in a number of courses and projects around Peru that embrace these topics. Lisset volunteered with the National Service of Natural Protected Areas (SERNANP) and at the Wayquecha Biological Station, where she assisted in a project on plant-hummingbird interactions.  Through her participation in the Course on Field Techniques and Tropical Ecology at the Cocha Cashu Biological Station in Manu National Park, she strengthened her knowledge of the tropical forest and started conducting her own research. As a Franzen Fellow, she will try to understand the habitat requirements of woodpeckers of the genera Campephilus and Celeus. She will address her research question by identifying the woodpecker species’ tree preferences when excavating their nesting cavities.

 

Diego Guevara got his biology degree from the Universidad Nacional Agraria La Molina (UNALM) in Lima, Peru and holds a master’s degree in applied ecology from the University of East Anglia, UK. He is an associate researcher at the Centro de Ornitología y Biodiversidad (CORBIDI) and general coordinator of the UNALM banding station. He has experience in projects related to the impact of human activities on biodiversity, with a special interest in the responses of bird communities and the habitat requirements of endangered species. Additionally, he is interested in studying the ecotoxicology and physiology of birds, which led him to apply to the Franzen Fellowship. His project will focus on the fluvial and bamboo forest bird community, studying the impacts of mining on its bird communities.

 

 

Patrick Newcombe attends the Sidwell Friends School in Washington, D.C., making him the youngest of our fellows. His interest in birds started as a young child, leading to his engagement in bird research. In 2018, with Osa Conservation in Costa Rica, he collected field data on the flocking behavior and diet of the endangered black-cheeked ant tanager (Habia atrimaxillaris). He is currently analyzing weather surveillance radar data to study the flight strategies of migratory birds on the Pacific Flyway as part of a project led by Dr. Kyle Horton from Cornell University. At Los Amigos, his project will focus on Manakin leks around the station, from which he will identify and learn about their habitat use patterns.

Stay tuned to learn more about our Fellows and their projects!

 

MAAP #96: Gold Mining Deforestation At Record High Levels In Southern Peruvian Amazon

Gold mining deforestation has been at record high levels in both 2017 and 2018 in the southern Peruvian Amazon.

Based on an analysis of nearly 500 high-resolution satellite images (from Planet and DigitalGlobe), we estimate the deforestation of 18,440 hectares across southern Peru during these last two years. That is equivalent to 45,560 acres (or 34,400 American football fields) in just two years.

The Base Map highlights this recent deforestation, with 2017 in red and 2018 in pink. The Reference Map in Annex 1 shows our full study area.

Base Map. Gold mining deforestation in southern Peruvian Amazon. Data- USGS/NASA, MAAP, SERNANP
Base Map. Gold mining deforestation in southern Peruvian Amazon. Data- USGS/NASA, MAAP, SERNANP

2017 had the highest gold mining deforestation on record at the time: 9,160 hectares (22,635 acres). According to recent research led by CINCIA (Centro de Innovación Científica Amazónica), this was the highest annual total on record dating back to 1985*.

In 2018, we found the gold mining deforestation was even higher: 9,280 hectares (22,930 acres).

Thus, combined, 2017-18 had the highest two-year deforestation total on record: 18,440 hectares (45,565 acres).

Note the location of Zooms (A-C) shown in greater detail below. These zooms represent three of the most threatened areas: A) La Pampa, B) Upper Malinowski, and C) Camanti.

Click (or right click) to enlarge (or download) images.

*CINCIA reports 9,860 hectares of gold mining deforestation in 2017 (CINCIA 2018, Caballero Espejo et al 2018), an estimate even higher than ours.

 

Zoom A: La Pampa

Image A shows the gold mining deforestation of 1,685 hectares (4,164 acres) between 2017 (left panel) and 2018 (right panel) in an area known as La Pampa (Madre de Dios region). Red indicates the major deforestation fronts.

MAAP96Image A. La Pampa. Data- Planet, MAAP
MAAP96Image A. La Pampa. Data- Planet, MAAP

As seen in the Land Use Map below (Annex 2), most of the recent mining deforestation in La Pampa is clearly illegal, concentrated in reforestation concessions and the buffer zone of Tambopata National Reserve.

According to the web portal GEOCATMIN (Geological Information System and Mining Register), developed by INGEMMET (Geological Mining and Metallurgical Institute of Peru), all titled mining concessions in the area are currently “without mining activity.” None are in authorized Exploration or Exploitation phase. Most of the mining activity is outside these concessions and in areas not authorized for mining.

 

Zoom B: Upper Malinowski

Image B shows the gold mining deforestation of 760 hectares (1,878 acres) between 2017 (left panel) and 2018 (right panel) along the upper stretches of the Malinowski River in the Madre de Dios region. Red indicates the major deforestation fronts.

As seen in the Land Use Map below (Annex 2), the recent gold mining deforestation along the Upper Malinowski is advancing in the Kotsimba Native Community and within the buffer zone of Bahuaja Sonene National Park.

According to GEOCATMIN, all titled mining concessions in the area are currently “without mining activity.” None are in authorized Exploration or Exploitation phase. Most of the mining activity is outside these concessions and in areas not authorized for mining.

 

Zoom C: Camanti

Image 4 shows the gold mining deforestation of 335 hectares (828 acres) between 2016 (left panel) and 2018 (right panel) in the Camanti area of the Cusco region. Red indicates the major deforestation fronts. Note the increasing proximity of the mining to Amarakaeri Communal Reserve.

Methodology

We analyzed high-resolution satellite imagery (DigitalGlobe and Planet) for both 2017 and 2018 and digitized all new gold mining deforestation. Given the widespread mining across a large area, we also used automated forest loss alerts based on medium resolution Landsat imagery (PNCB/MINAM) to guide our analysis.

MAAP, an initiative of the organization Amazon Conservation, uses cutting-edge satellite technology to monitor deforestation in near real-time in the megadiverse Andean Amazon (Peru, Colombia, Ecuador, and Bolivia).

The monitoring is based on 5 satellite systems: Landsat (NASA/USGS), Sentinel (European Space Agency), PeruSAT-1, and the companies Planet and DigitalGlobe. For more information about our innovative methodology, see this recent paper in Science Magazine.

Launched in 2015, MAAP has published nearly 100 high-impact reports on the major Amazonian deforestation issues of the day.

Here, we present our third annual synthesis report with the objective to concisely describe the bigger picture: Deforestation trends, patterns, hotspots and drivers across the Andean Amazon.

Our principal findings include:

Trends: Deforestation across the Andean Amazon has reached 4.2 million hectares (10.4 million acres) since 2001. Annual deforestation has been increasing in recent years, with a peak in 2017 (426,000 hectares / 1,052,668 acres). Peru has had the highest annual deforestation, followed by surging Colombia (in fact, Colombia surpassed Peru in 2017). The vast majority of the deforestation events are small-scale (‹5 hectares / 12.35).

Hotspots: We present the first regional-scale deforestation hotspots map for the Andean Amazon, allowing for spatial comparisons between Peru, Colombia, and Ecuador.  We discuss six of the most important hotspots.

Drivers: We present MAAP Interactive, a dynamic map with detailed information on the major deforestation drivers: gold mining, agriculture (oil palm and cacao), cattle ranching, logging, and dams. Agriculture and ranching cause the most widespread impact across the region, while gold mining is most intense southern Peru.

Climate Change. We estimated the loss of 59 million metric tons of carbon in the Peruvian Amazon during the last five years (2013-17) due to forest loss. In contrast, we also show that protected areas and indigenous lands have safeguarded 3.17 billion metric tons of carbon.

Trends by Country

Over the past 17 years (2001-2017), deforestation has surpassed 4.2 million hectares (10.4 million acres) in the Andean Amazon (see green line). Of this total, 50% is Peru (2.1 million hectares/5.2 million acres), 41% Colombia (1.7 million hectares/4.27 million acres), and 9% Ecuador (887,000 acres/359,000 hectares). This analysis did not include Bolivia.

Since 2007, there has been an increasing deforestation trend, peaking during the past two years (2016-17). In fact, 2017 has the highest annual forest loss on record with 426,000 hectares (over one million acres), more than double the total forest loss in 2006.

Peru had the highest average annual Amazonian deforestation between 2009 and 2016. The past four years have the highest annual deforestation totals on record in the country, with peaks in 2014 (177,566 hectares/439,000 acres) and 2016 (164,662 hectares/406,888 acres). According to new data from the Peruvian Environment Ministry, there was an important decline in 2017 (155,914 hectares/385,272 acres), but it is still the fourth highest annual total on record.

There has been a surge of deforestation in Colombia during the past two years. Note that in 2017, Colombia surpassed Peru with a record high of 214,700 hectares (530,400 acres) deforested.

Deforestation is also increasing in Ecuador, with highs of 32,000 hectares (79,000 acres) in 2016 and 55,500 hectares (137,000) acres in 2017.

For context, Brazil has had an average deforestation loss rate of 639,403 hectares (1.58 million acres) over the past several years.

* Data: Colombia & Ecuador: Hansen/UMD/Google/USGS/NASA; Peru: MINAM/PNCB, UMD/GLAD. While this information includes natural forest loss events, it serves as our best estimate of deforestation resulting from anthropogenic causes.  It is estimated that the non-anthropic loss comprises approximately 3.5% of the total loss. Note that the analysis does not include Bolivia.


Trends by Size

The pattern related to the size of deforestation events in the Andean Amazon remained relatively consistent over the last 17 years. Most noteworthy: the vast majority (74%) of the deforestation events are small-scale (‹5 hectares). Only 2% of deforestation events are large-scale (>100 hectares). The remaining 24% are medium-scale (5-100 hectares).

These results are important for conservation efforts.  Addressing this complex situation – in which most of the deforestation events are small-scale – requires significantly more attention and resources.  In addition, while large-scale deforestation (usually associated with agro-industrial practices) is not that common, it nonetheless represents a serious latent threat, due to the fact that only a small number of agro-industrial projects (for example, oil palm) are able to rapidly destroy thousands of acres of primary forest.


II. Deforestation Hotspots

Image 2: Deforestation hotspots 2015-2017. Data: Hansen/UMD/Google/USGS/NASA.

We present the first regional-scale deforestation hotspots map across the Andean Amazon (Colombia, Ecuador, Peru).  Image 2 shows the results for the past three, 2015 – 2017.

The most critical zones (“high” deforestation density) are indicated in red. They include:

A. Central Peruvian Amazon: Over the last 10 years, this zone, located in the Ucayali and Huánuco regions, has consistently had one of the largest concentrations of deforestation in Peru (Inset A).  Its principal drivers include oil palm and cattle grazing.

B. Southern Peruvian Amazon: This zone, located in the Madre de Dios region, is impacted by gold mining (Inset B1), and increasingly by small- and medium-scale agriculture along the Interoceanic Highway (Inset B2).

C. Central Peruvian Amazon: A new oil palm plantation located in the San Martín region has been identified as a recent large-scale deforestation event in this zone (Inset C).

D. Southwestern Colombian Amazon: Cattle grazing is the principal deforestation driver documented in this zone, located in the departments of Caquetá and Putumayo (Inset D).

E. Northern Colombian Amazon: There is expanding deforestation along a new road in this zone, located in the department of Guaviare (Inset E).

F. Northern Ecuadoran Amazon: This zone is located in the Orellana province, where small- and medium-scale agriculture, including oil palm, is the principal driver of deforestation (Inset F).

 

 

 

 

 


III. Drivers of Deforestation     

MAAP Interactive (screenshot)
MAAP Interactive (screenshot)

One of the main objectives of MAAP is to improve the availability of precise and up-to-date information regarding the current drivers (causes) of deforestation in the Andean Amazon.  Indeed, one of our most important advances has been the use of high-resolution imagery to identify current deforestation drivers.

In order to improve the analysis and understanding of the identified drivers, we have created an Interactive Map that displays the spatial location of each driver associated with every MAAP report.  An important characteristic of this map is the ability to filter the data by driver, by selecting the boxes of interest.

Image 3 shows a screenshot of the Interactive Map.  Note that it contains detailed information on these principal drivers: gold mining, oil palm, cacao, small-scale agriculture, cattle pasture, logging roads, and dams.  It also includes natural causes such as floods, forest fires, and blowdowns.  In addition, it highlights deforestation events in protected areas.

Below, we discuss the principal drivers of deforestation and degradation in greater detail.

Other crops (dark green)

Agricultural activity is one of the principal causes of deforestation in the Andean Amazon.

The majority of agriculture-related deforestation is caused by small- and medium-scale plantations (‹50 hectares).

Deforestation for large-scale, agro-industrial plantations is much less common, but represents a critical latent threat.

 

 


Large-scale Agriculture

We have documented five major deforestation events produced by large-scale plantations since 2007:  four of these occurred in Peru (three of which are related to oil palm and one to cacao) and one in Bolivia (resulting from sugar cane plantations).

First, between 2007 and 2011, two large-scale oil palm plantations caused the deforestation of 7,000 hectares on the border between Loreto and San Martín (MAAP #16).  Subsequent plantations in the surrounding area caused the additional deforestation of 9,800 hectares.

It is important to note that the Peruvian company Grupo Palmas is now working towards a zero deforestation value chain and has a new sustainability policy (see Case C of MAAP #64).

Next, between 2012 and 2015, two other large-scale oil palm plantations deforested 12,000 hectares in Ucayali  (MAAP #4, MAAP #41).

Between 2013 and 2015, the company United Cacao deforested 2,380 hectares for cacao plantations in Loreto (MAAP #9, MAAP #13, MAAP #27, MAAP #35).

Deforestation from large-scale agriculture decreased in Peru between 2016 and 2017, but there was one notable event: an oil palm plantation of 740 hectares in San Martín (MAAP #78).

Another notable case of deforestation related to large-scale agriculture has been occurring in Bolivia, where a new sugarcane plantation has caused the deforestation of more than 2,500 hectares in the department of La Paz.

Additionally, we found three new zones in Peru characterized by the deforestation pattern produced by the construction of organized access roads which have the potential of becoming large-scale agriculture areas (MAAP #69).


Small and Medium-scale Agriculture

Deforestation caused by small- and medium-scale agriculture is much more widespread, but it is often difficult to identify the driver from satellite imagery.

We have identified some specific cases of oil palm in Huánuco, Ucayali, Loreto, and San Martín (MAAP #48, MAAP #26, MAAP #16).

Cacao and papaya are emerging drivers in Madre de Dios.  We have documented cacao deforestation along the Las Piedras River (MAAP #23, MAAP #40) and papaya along the Interoceanic Highway (MAAP #42).

Corn and rice cultivation appear to be turning the area around the town of Iberia into a deforestation hotspot (MAAP #28).  In other cases, we have documented deforestation resulting from small- and medium-scale agriculture, though it has not been possible to identify the type of crop (MAAP #75, MAAP #78).

Additionally, small-scale agriculture is possibly a determining factor in the forest fires that degrade the Amazon during the dry season (MAAP #45, MAAP #47).

The cultivation of illicit coca is a cause of deforestation in some areas of Peru and Colombia.  For example, in southern Peru, the cultivation of coca is generating deforestation within the Bahuaja Sonene National Park and its surrounding areas.


Cattle Ranching

By analyzing high-resolution satellite imagery, we have developed a methodology for identifying areas deforested by cattle ranching.*

Image 5 shows the results of the Interactive Map when applying the “Cattle pasture” filter, indicating the documented examples in Peru and Colombia.

Legend:
Cattle ranching (orange)

Cattle ranching is the principal driver of deforestation in the central Peruvian Amazon (MAAP #26, MAAP #37, MAAP #45, MAAP #78). We also identified recent deforestation from cattle ranching in northeastern Peru (MAAP #78).

In the Colombian Amazon, cattle ranching is one the primary direct drivers in the country’s most intense deforestation hotspots (MAAP #63, MAAP #77).

* Immediately following a major deforestation event, the landscape of felled trees is similar for both agriculture and cattle pasture.  However, by studying an archive of images and going back in time to analyze older deforestation cases, it is possible to distinguish between the drivers.  For example, after one or two years, agriculture and cattle pasture appear very different in the images. The former tends to have organized rows of new plantings, while the latter is mostly grassland.


Gold Mining

Gold Mining (yellow)

*With dot indicates within protected area

The area that has been most impacted by gold mining is clearly the southern Peruvian Amazon, where we estimate the total deforestation of more than 63,800 hectares. Of this, at least 7,000 hectares have been lost since 2013.  The two most critical zones are La Pampa and Alto Malinowski in Madre de Dios (MAAP #87, MAAP #75, MAAP #79).  Another critical area exists in Cusco in the buffer zone of the Amarakaeri Communal Reserve, where mining deforestation is now less than one kilometer from the boundary of the protected area (MAAP #71).

It is important to highlight two important cases in which the Peruvian government has taken effective actions to halt illegal mining within protected areas (MAAP #64).  In September 2015, illegal miners invaded Tambopata National Reserve and deforested 550 hectares over the course of a two-year period.  At the end of 2016, the government intensified its interventions and the invasion was halted in 2017. In regards to Amarakaeri Communal Reserve, in June 2015 we revealed the mining invasion deforestation of 11 hectares.  Over the course of the following weeks, SERNANP and ECA Amarakaeri implemented measures and rapidly halted the illegal activity.

Other small gold-mining fronts are emerging in the northern and central Peruvian Amazon (MAAP #45, MAAP #49).

In addition, we have also documented deforestation linked to illegal gold-mining activities in the Puinawai National Park in the Colombian Amazon.

 

 

 

 


Logging

In MAAP #85 we proposed a new tool to address illegal logging in the Peruvian Amazon: utilize satellite imagery to monitor construction of logging roads in near real-time.

Image 7 shows the results of the Interactive Map when applying the “Logging roads” filter.

Legend:
Logging Road (purple)

We estimate that 2,200 kilometers of forest roads have been constructed in the Peruvian Amazon during the last three years (2015-2017).  The roads are concentrated in southern Loreto, Ucayali, and northwestern Madre de Dios.

 

 

 

 

 

 

 

 

 


Roads

Image 8: Interactive map, roads. Data: MAAP.
Image 8: Interactive map, roads. Data: MAAP.

It has been well-documented that roads are one of the most important drivers of deforestation in the Amazon, particularly due to the fact that they facilitate human access and activities related to agriculture, cattle ranching, mining, and logging.

Image 8 shows the results of the Interactive Map when applying the “Roads” filter.

Legend:
Road (gray)

We have analyzed two controversial proposed roads in Madre de Dios, Peru.

The Nuevo Edén – Boca Manu – Boca Colorado road would traverse the buffer zone of two protected areas: Amarakaeri Communal Reserve and Manu National Park (MAAP #29).

The other, the Puerto Esperanza-Iñapari road, would traverse the Purús National Park and threaten the territory of the indigenous peoples in voluntary isolation who live in this remote area (MAAP #76).

 

 

 

 

 

 


Hydroelectric dams

Hydroelectric Dam (light blue)

To date, we have analyzed three hydroelectric dams located in Brazil.  We have documented the loss of 36,100 hectares of forest associated with flooding produced by two dams (San Antonio and Jirau) on the Madeira River near the border with Bolivia (MAAP #34).  We also analyzed the controversial Belo Monte hydroelectrical complex located on the Xingú River, and estimate that 19,880 hectares of land have been flooded. According to the imagery, this land is a combination of forested areas and agricultural areas (MAAP #66).

Additionally, we show a very high-resolution image of the exact location of the proposed Chadín-2 hydroelectric dam on the Marañón River in Peru (MAAP #80).

Our first report on this sector focused on Yasuní National Park in the Ecuadorian Amazon.  We documented the direct and indirect deforestation amounts of 417 hectares (MAAP #82).

We also show the location of recent deforestation in two hydrocarbon block in Peru: Block 67 in the north and Blocks 57 in the south.

 

 

 

 

 

 

 

 

 

 


Climate Change

Tropical forests, especially the Amazon, sequester huge amounts of carbon, one of the main greenhouse gases driving climate change.

In MAAP #81, we estimated the loss of 59 million metric tons of carbon in the Peruvian Amazon during the last five years (2013-17) due to forest loss, especially deforestation from mining and agricultural activities. This finding reveals that forest loss represents nearly half (47%) of Peru’s annual carbon emissions, including from burning fossil fuels.

In contrast, in MAAP #83 we show that protected areas and indigenous lands have safeguarded 3.17 billion metric tons of carbon, as of 2017. That is the equivalent to 2.5 years of carbon emissions from the United States.

The breakdown of results are:

1.85 billion tons safeguarded in the Peruvian national protected areas system;

1.15 billion tons safeguarded in titled native community lands; and

309.7 million tons safeguarded in Territorial Reserves for indigenous peoples in voluntary isolation.

“I have been insulted. I have been threatened. But here I stand to protect my forest.”

Flor Rumayna’s story is one of strength in the face of adversity and of understanding that without protecting nature, we can’t thrive.

Deep in the Amazon rainforest of Peru, Flor and her husband Gilberto have been running this forest-friendly lodge for many years now, right on the edge of Huitoto Lake. The lush Amazonian forest surrounding the lake is the main draw for adventurers looking to experience nature firsthand. 

But this is not paradise. 

Flor’s life has been threatened many times. This region is particularly affected by illegal activities like gold mining and logging, and because Flor has kept her forest pristine, many try to take its natural resources by force. 

Flor and her family have been fighting to protect this forest with all they have – but it hasn’t been enough. So, with the support of people like you, Friend of the Amazon, we stepped in to help.

Our Southwest Amazon Drone Center is training local landowners, indigenous communities, students, and government officials to use cutting-edge technology like satellite imagery, smartphone apps, and drones to monitor and stop deforestation. We provide locals the technology, knowledge, legal support and connections so they can safely and effectively take action on the ground.

 Flor is one of the first women in Peru to be certified as a drone pilot. With our support – and yours – she is leading the path for others to take charge of conservation in a safe and effective way.

Joining forces with neighbors? Think twice!

The russet-backed oropendola (Psarocolius angustifrons) is one of the most common and widespread of the oropendola passerine birds in the Amazon. They are mostly dull brown with rufescent rump and olive tone to head. This species has three subspecies: P. a. astrocastaneus, on the western Andean slope; P. a. alfredi in the eastern Andean subtropical forest; and P. a. angustifrons in Amazonia. These subspecies differ primarily in bill and face coloration and vocalizations. During the breeding season, they are seen arduously building their characteristic basket-like nest that hang from tree branches in riparian and second-growth habitats. These closed nests keep their eggs and chicks protected from predators.

The violaceous jay (Cyanocorax violaceus) is a colorful and gregarious member of the crow family of northern South America. This jay species is predominantly dark violet-blue, with a black facial mask. The violaceous jay can be found in a variety of forest habitats, including degraded forest, but is especially common along riparian corridors and forest edges. They are omnivorous and can be seen eating fruits, insects and bird and reptile eggs.

A great contrast is easily noticed between the species: some think that the call of the russet-backed oropendola sounds like water drops, while that of the violaceous jay strikes some as similar to a car horn. The species also have similarities: they are conspicuous resident and widely distributed species in the Amazon.

Brown capuchin (Cebus apella) might look cute but
they are fierce predators. | PC Claudia Rohr

These species have something else in common: confrontations with brown capuchin monkeys! Brown capuchins (Cebus apella) feed mostly on fruits and invertebrates, but from time to time enjoy a meal of bird eggs and chicks. Quite often, a group of these monkeys can be seen climbing up the trees right outside the office at Los Amigos, where the oropendolas and jays are nesting close to each other. When the brown capuchins arrive, adults of both bird species first make their presence known with their characteristic calls. When the monkeys draw close to the nests, the oropendolas and jays cooperatively try to chase them away. These encounters conclude with either the monkeys leaving empty-handed or the birds suffering broken nests and lost eggs.

The striking cooperation between these bird species is short-lived. Jays will try to take eggs and chicks from other bird nests, including fiercely defended russet-backed oropendola nests.  For the oropendolas and violaceous jays, the expression “the enemy of my enemy is my friend” is applicable only when the common enemy is visible.

 

MAAP #95: Oil Palm Baseline for The Peruvian Amazon

In previous reports, we have documented that oil palm is one of the deforestation drivers in the Peruvian Amazon (MAAP #41, #48). However, the full extent of this sector’s deforestation impact is not well known.

A newly published study assessed the deforestation impacts and risks posed by oil palm expansion in the Peruvian Amazon. Here, we review some of the key findings.

We first present a Base Map of oil palm in the Peruvian Amazon, highlighting the plantations that have caused recent deforestation. We then show two zooms of the most important oil palm areas, located in the central and northern Peruvian Amazon, respectively.

In summary, we document over 86,600 hectares (214,000 acres) of oil palm, of which we have confirmed the deforestation of at least  31,500 hectares for new plantations (equivalent to nearly 59,000 American football fields).

In other words, yes oil palm does cause Amazon deforestation, but not nearly as much as Asia.
