Atelopus pulcher, a critically endangered harlequin toad that has vanished from much of its range due to the Chytrid fungus. This genus has been particularly hard hit by chytrid with many species considered either extinct or endangered.

Silverstone's poison frog (Ameerega silverstonei) an endangered poison frog from the cloud forests of Peru. It is threatened by habitat loss and unsustainable poaching for the pet trade.

The sky blue poison frog (Hyloxalus azureiventris) a secretive and endemic poison frog from Peru. It is considered to be endangered and is only known from a narrow mountain gradient.

A juvenile California Condor (Gymnogyps californianus), but not just any California condor. This is 1k, the first condor to successfully fledge in Zion National Park, Utah.

Endangered Species Research

Santa Cruz Long-toed Salamander (Ambystoma macrodactylum croceum), an endangered subspecies that only breeds in a handful of ponds in Santa Cruz and Monterey counties in California. Habitat development, climate change, and rising sea levels put this species future in jeopardy - none of its current breeding ponds will still be suitable within the next half century. Biologists investigate their ecology in order to construct artificial ponds to ensure their future.

A northwestern pond turtle (Actinemys marmorata) in a cold water stream in California. This species inhabits a variety of water bodies in its range from permanent streams and rivers to seasonal cattle ponds. Despite its adaptability populations have been declining and the species is considered threatened.

California tiger salamander (Ambystoma californiense), an endangered mole salamander endemic to California. They are reliant on vernal pond habitat which has unfortunately been largely lost across their former range.

The Dolloff cave spider (Meta dolloff) is often referred to as one of the rarest spiders of North America. It is also one of the few that are officially recognized as threatened speices. It only lives in a few caves in Santa Cruz and Monterey counties.

A California condor (Gymnogyps californianus), from Pinnacles National park. In the late 1980s, the population of these birds dropped to 27 individuals and all remaining individuals were taken into captivity for breeding programs. Since then over 1000 condors have hatched mostly in captive breeding programs but also in the wild. Nearly all adults are numbered for monitoring - this is #726 a female called Little Stinker, she was hatched at San Diego Wild Animal park in 2013 and released into the wild in 2016 and is named after the winning plane in the US Female Aerobatic Championship in the late 1940s.
