Chocó-Darien Hotspot

Friday, August 6th, 2010

ecoReserve’s first reserve located in the Mamoni Valley is part of the Tumbes-Chocó-Magdalena Hotspot and includes a small portion of the Chocó/Darién wet region, one of the two major regions in the hotspot.

ecoReserve’s Mamoni Valley reserve falls in two of the 34 internationally recognized biodiversity hotspots: 1) the Mesoamerica Biodiversity Hotspot and 2) the Tumbes-Choco-Magdalena Hotspot. Although both start in Panama, the Mesoamerica Biodiversity Hotspot runs northward, but the Tumbes-Choco-Magdalena Hotspot runs southward. Because we have already discussed the Mesoamerica Biodiversity Hotspot, this post will focus on the Tumbes-Choco-Magdalena Hotspot. The Tumbes-Chocó-Magdalena Hotspot starts in the southeastern portion of Mesoamerica and extends to the northwestern corner of South America with a reach of 1600 kilometers, which is close to 1000 miles. The hotspot is divided into two main regions, the northernmost Chocó/Darién wet and moist forests located in the Darién Province in Panama and the Chocó region in western Colombia to the southernmost Tumbesian dry forests of Ecuador and the northwestern part of Peru.

The Darién Province is one of the most diverse, remote regions in Central America and is protected by dense pristine forests and jungle. At over 3 million acres, it is the largest province in Panama, the most sparsely populated, and the least well known. It is a region of dense tropical rainforest and is among the most complete ecosystems of all tropical America. The Darién is mostly uninhabited mountains, jungle, and swamplands, and it has one of the richest ecosystems of the American tropics. It is also home to many endangered species, such as the jaguar, the giant anteater, the harpy eagle, and the tapir.

Until 20 years ago, there were no roads in the Darién, and travel through the region was very difficult. Before the roads were built, the indigenous people of the area, the Embera, Wounaan, and Kuna, relied mainly on water transportation because they live in settlements scattered along the river valley . Today the Pan-American Highway cuts through the middle of Darien. This gravel highway extends down as far as the town of Yaviza, which is the beginning of the famed Darien Gap. This 100 km gap, which is the only uncompleted piece of the the Pan-American Highway, is impossible for travelers to pass and survive. The highway poses another danger as well. Because the highway connects overland commerce between North and South America, it has opened up the region to cattle ranchers, loggers, and landless peasants. As a result, both the natural forest and the indigenous people of the Darién are being threatened.

The biggest objection to completion of the highway is its effect on the region’s ecological balance and the danger it poses to the survival and habitat of the indigenous people living in the region. It would also extend the already dramatic deforestation of the area.

Biological Corridors Needed to Protect Species at Risk: Report From Canada

Biological Corridors and the Importance of Biological Corridors to Ensure Species Survival

We thought we would take a moment to discuss another part of the world where species are endangered and where biological corridors are needed. Let’s recall the idea of a biological corridor. A wildlife corridor is a route comprising a continuous, or nearly continuous, stretch of open land, woodland or water, which facilitates the movement of wildlife species, the aim of which is to prevent the genetic isolation of wildlife populations.

As we talked about in an earlier entry, ecoReserve is part of the Mesoamerican Biological Corridor and It was started in 1998 to keep 106 critically endangered species from going extinct. Biological corridors are required everywhere to ensure species survival.

A new report out of Canada says that ” Ensuring Canada’s woodland caribou, eastern wolf and other at-risk species survival will require bigger, more interconnected parks”. This report points to the importance of biological corridors being started in Canada to protect the survival of those at-risk species and once again highlighting the importance of setting up Biological Corridors around the world as a means of protecting all at-risk species and their habitats.

The report writes that “Canada’s parks are an uneven patchwork in terms of how much protection they offer endangered wildlife, and concluded the third annual review of how wildlife are faring in Canada’s parks released Friday by the Canadian Parks and Wilderness Society.

“There are quite a few [species] that in fact rely very heavily on parks as their main habitat,” said Eric Hébert-Daly, the group’s executive director. “Having really big parks, to keep large habitat in tact, having them connected to other protected areas is quite essential.”

“The smaller ones that aren’t connected tend to be the ones that have a hard time.””

The report praises the Canadian government and its efforts to create more parks, including the recently announced Gwaii Haanas National Marine Conservation Area in B.C., Sable Island in Nova Scotia and the Mealy Mountains in Newfoundland and Labrador.

It also notes that other efforts such as establishing a protective zone around Ontario’s Algonquin Park and connecting parks in the Rocky Mountains have had a positive effect on species like the eastern wolf and grizzly bear.

However some species (such as woodland caribou) are still struggling and this is mostly due to human activity.

“The moment you start developing roads, the predator-prey relationship gets unbalanced,” he said. Caribou may have a harder time fleeing and hiding from wolves, for example, and are very sensitive to development.”

The Mesoamerican Biological Corridor – What is it, why is it significant?

The Mesoamerican Biological Corridor – What is it and why is it significant?

dark green = current reserves | light green = developing reserves

The ecoReserve project in Panama is located within the Mesoamerican Biological Corridor, which is also known as the Jaguar Trail or Path of the Panther. We thought we’d take a moment to talk about why this is significant.

First, what is a biological corridor (also known as wildlife corridor)? A wildlife corridor is a route comprising a continuous, or nearly continuous, stretch of open land, woodland or water, which facilitates the movement of wildlife species, the aim of which is to prevent the genetic isolation of wildlife populations.

The Mesoamerican Biological Corridor, specifically, is a large habitat corridor in , stretching from southeastward through most of Central America, connecting several national parks. It was started in 1998 to keep 106 critically endangered species from going extinct.

Mesoamerica is made up of the five southern states of Mexico and the Central American countries of Guatemala, Belize, El Salvador, Honduras, Nicaragua, Costa Rica, and Panama. These governments agreed to coordinate their efforts to encourage a huge system of interconnected parks, reserves and wildlife corridors that literally link North America to South America. ecoReserve will be adding one additional reserve to this system.

The Mesoamerican region is very large and covers 768,990 square kilometers. It includes lowland rainforests, pine savannas, semi-arid woodlands, grasslands, high mountain forests, and coral reefs. Although the region contains only 0.5 percent of the world’s land surface, Mesoamerica is home about 7 percent of the earth’s biological diversity.

In recent decades, Mesoamerica has seen some of the highest deforestation rates in the world; between 1980 and 1990, deforestation averaged 1.4 percent annually, and it is estimated that 80 percent of the area’s original habitat has been cleared or severely modified. More than half of Mesoamerica’s forests have been lost and approximately 90 percent of its primary or “frontier” forests have been logged, converted to agriculture, or replaced with tree plantations.

Wildlife corridors become especially important in the face of human activities such as roads, development, or logging that may bisect the routes that animals normally traverse. Animal movement allows an exchange of individuals between populations, which may help prevent the negative effects of inbreeding and reduced genetic diversity that often occur within isolated populations.

In the Mamoni Valley, where the ecoReserve project will be located, the wildlife corridor has been partially degraded by logging and cattle-ranching which has turned primary forest into pastures or barren dirt. Animals are reluctant to traverse these open areas because it makes them vulnerable to predators.

ecoReserve will be reforesting and restoring degraded land and protecting primary rainforest that still exists within the Mamoni Valley. The ecoReserve reserve will also provide a buffer zone for the protected primary rainforest land of the indigenous Kuna that is still intact. We are looking forward to providing one more link in the chain of reserves that protect the famed Jaguar Trail.

ecoReserve and the Mamoni Valley

Wednesday, June 23rd, 2010

In advance of the launch of our new model we wanted to introduce The Mamoni Valley (the site of our first reserves), why it is significant, the ecoReserve model and our ecological strategic contribution in the Valley.

The Mamoni Valley

The Mamoni Valley is located in narrowest portion of the North American continent (central Panama), which separates the Atlantic and Pacific Oceans. The 28000 acre Valley is part of a world recognized biodiversity hotspot and home to a diverse range of plants and animals. In addition, it is an important migration stop-over region for many North and South American birds.

For the past forty years, large areas of the valley have been deforested due to increased demands for agriculture and ranching production. Currently, the Mamoní Valley is severely fragmented and degraded which threatens the watershed and biodiversity.

What is biodiversity?

Biological diversity means the diversity, or variety, of plants and animals and other living things in a particular area or region. For instance, the species that inhabit Los Angeles are different from those in San Francisco, and desert plants and animals have different characteristics and needs than those in the mountains, even though some of the same species can be found in all of those areas. Biodiversity also means the number, or abundance of different species living within a particular region.

Physical Characteristics of the Mamoni Valley and Why It Is Significant

Part of Mesoamerican Biological Corridor: The Mesoamerican Biological Corridor is a large habitat corridor in Mesoamerica, stretching from Mexico southeastward through most of Central America, connecting several national parks. It was started in 1998 to keep critically endangered species from going extinct.

Part of Mesoamerica Biodiversity Hotspot: A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction. The Mesoamerican forests are the third largest among the world’s hotspots. Spanning most of Central America, the Mesoamerica Hotspot encompasses all subtropical and tropical ecosystems from central Mexico to the Panama Canal. This includes all of Guatemala, Belize, El Salvador, Honduras, Nicaragua, and Costa Rica, as well as a third of Mexico and nearly two-thirds of Panama.

Borders Kuna Yala (land of indigenous Kuna): Kuna Yala is an autonomous territory or comarca in Panama, inhabited by the Kuna indigenous people. The name means “Kuna-land” or “Kuna mountain” in the Kuna language

Borders Chagres National Park: Chagres National Park was established in 1985. The Chagres National Park covers 129,000 hectares and is 40 kilometers from Panama City.

About ecoReserve and The Model

ecoReserve has developed a new model to address the negative social, economic and environmental influences impacting the Mamoní Valley. The model includes three types of reserves, conservation, reforestation and sustainable livelihoods. These reserves will successfully build a multi-faceted, ecological restoration program that increases the health of the rainforest and improves the livelihoods of the people who depend upon the land.

Our ecological strategic contribution by establishing the reserves in the Mamoni Valley:
– Create buffer zone for Kuna Yala and Chagres National Park
– Strengthen biological corridor
– Protect biodiversity and animal habitats
