Vancouver Island Marmot (Marmota vancouverensis)

As its name suggests, this furry herbivore, about the size of a large house cat, is found only on Vancouver Island in British Columbia, Canada. Small colonies of one to three family units live in high-elevation forests on the island. No one is quite sure how many marmots there were before counting began in 1979, but numbers dwindled from a high of several hundred in the mid-1980s to a mere 35, all in one spot, in 2004.

Researchers are still studying the reasons behind the marmot’s decline, but clear-cutting the island’s forests likely had some effect. Without the cover of trees, the marmots may have become more vulnerable to predation by birds, wolves, cougars or a combination of the three. A captive-breeding program has had some success, and dozens of marmots have been released on Vancouver Island since 2003. However, there are still some worries, as a recent study found that captive-born marmots are even more vulnerable to golden eagles than their wild-born brethren. – SZ

Hunting actually was a minor contributor to the Red Wolf demise. Habitat loss was a major contributor, but the finishing blow was the expansion eastward of the Coyote. They crossbred with the Red Wolf and just about wiped them out.

There was a viable population of the wolf in southern AR until the late 1940s. That's when coyotes began to show up. By the mid to late 1950s the wolf had disappeared.

Add an Ivory Billed Woodpecker!

thank you, thank you, thank you from my heart for saving the habitat as well as these beautiful wolves. i feel a strong connection to all wolves and this story was uplifting, encouraging, and worth my two minute feeble effort to say thank you for caring about and taking action to save these animals.

Our eyes are in the front of our heads but we are blind to the future of the earth and its inhabitants. We are the last species to evolve from earth's origins (not inclduing nuclear mutations) and we seem to be intent on being its last to survive our own predatory habits. Wait. Isn't that why we have wars, to eliminate ourselves?

A porpoise endemic to Mexico, the vaquita (Phocoena sinus) is now widely-recognized by marine mammal biologists as the most-endangered marine mammal in the world (Jaramillo-Legorreta et al. 2007). The species is listed as Critically Endangered by the IUCN Red List authority, and as Endangered on the U.S. Endangered Species List, and Mexico has also listed the vaquita as Endangered and considered it the first of five top-priority species for conservation action (SEMARNAT 2008).

Population size of the vaquita was estimated in 2008 from a line-transect survey. The resulting estimate was 245 individuals (Gerrodette et al. 2011). This is much lower than a 1997 estimate using similar methods (567 individuals - Jaramillo-Legorreta et al. 1999). From this, it was estimated that the population has been declining by 7.6% per year, and if the decline has continued in the last couple of years, then there would likely be only about 200 porpoises left now. All this means there is a window of at most a few years in which to implement solutions to save the species (see Jaramillo-Legorreta et al. 2007).
