6 RARE FROGS DISCOVERED IN HAITI'S MOUNTAINS

In October 2010, a team of scientists set out for the remote mountains of southern Haiti in search of lost frogs. The expedition—led by Dr Robin Moore of Conservation International and Dr. Blair Hedges of Pennsylvania State University—was part of a worldwide Conservation International project aimed at finding amphibian species that have not been sighted in over a decade and which are feared to be extinct.

Haiti's amphibians are gravely threatened by the near total clear-cutting of the country's tropical forests. Less than two percent of Haiti's original forests remain intact and as a result, 92 percent of the country's 49 known native amphibian species are threatened.

Dr. Moore and Dr. Hedges explored two mountain forest regions of Haiti, the Massif de la Hotte in the southewst and the Massif de la Sell in the southeast. They had hoped to find just one of Haiti's elusive frog species. Instead, they found six critically endangered frogs, none of which had been seen in nearly twenty years.

For a country that has faced devistation and pain since the 2010 earthquake that struck just outside the capital city of Port-au-Prince, the rediscovery of these rare endemic frogs provides a rare beacon of pride and hope amidst otherwise incomprehensible pain and struggle.

"Clearly, the health of Haiti's frogs is not anyone's primary concern here. However, the ecosystems these frogs inhabit, and their ability to support life, is critically important to the long-term well-being of Haiti's people, who depend on healthy forests for their livelihoods, food security and fresh water. Amphibians are what we call barometer species of our planet's health. They're like the canaries in the coal mine. As they disappear, so too do the natural resources people depend upon to survive."

The six species of frogs rediscovered by Dr. Moore and Dr. Hedges included five species last seen in 1991—the Hispaniolan ventriloquial frog, Mozart's frog, La Hotte glanded frog, Macaya breast-spot frog, Hispaniolan crowned frog—and one species last seen in 1996—the Macaya burrowing frog.

Haiti has suffered many environmental and human disasters in addition to the January 2010 earthquake. More recently, the country has been battling a cholera outbreak. In the midst of these human struggles, the natural environment of Haiti is also suffering. Without the immediate action by international conservation organizations and government agencies, Haiti will surely experience widening habitat destruction and mass extinctions. The rediscovery of six frog species previously feared to be extinct offers renewed hope for conservationists and evidence of the resiliency of the region's rare wildlife.

A Strategy for Tripling Tiger Numbers

The number of wild tigers protected in the nature reserves of Asia could be increased threefold simply by connecting existing reserves with corridors of habitat. Such corridors would allow tigers to move between isolated reserves and would encourage the mixing of individuals within the various sub populations and enable the influx of tigers into areas that suffer declines. This new strategy of tiger management was suggested in a paper published recently in the journal Conservation Letters.

There are currently about 3,200 wild tigers in Asia. This number represents a small fraction of the tiger population that was present in the region a century ago. In the early 1900s, wild tiger numbers were close to 100,000. But since that time, the species has suffered drastic declines due to poaching, habitat destruction and loss of prey populations. To complicate the population decline, today's remaining tigers are isolated in small populations scattered across 13 countries.
