California Tiger Salamander:  The California tiger salamander (Ambystoma californiense) is an endangered amphibian native to Northern California.  Previously considered to be a Tiger Salamander subspecies, the California tiger salamander, which is endemic, was recently designated a separate species.


Callippe Silverspot Butterfly:  The Callippe Silverspot Butterfly (Speyeria callippe callippe) is a federal endangered species in the brush-footed butterfly family Nymphalidae. It is a member of the Heliconiinae, the subfamily known as longwings. The adult has a wingspan of just over two inches. The wings are eyecatching with a brown, tan, and black scalloped pattern on their surfaces and orange-brown with characteristic silver spots on the undersides. The wings and abdomen are hairy.

This subspecies occurs in a few isolated spots in the San Francisco Bay Area, mostly near Oakland and Berkeley. Its native region is now extensively developed and heavily populated, leaving the butterfly critically endangered. Recently the subspecies has been known only from two spots near South San Francisco, the hills above Pleasanton, Sears Point in the North Bay, and in spots between Vallejo and Cordelia.

Loss of habitat is the primary cause of endangerment. Any native grassland that remains in the butterfly's habitat is currently disappearing due to varied causes, including development, off-road vehicles, grazing, and invasive plants.



Chinook Salmon:  The Chinook salmon (Oncorhynchus tshawytscha) is a species of anadromous fish in the salmon family.  It is a Pacific Ocean salmon and is variously known as the king salmon, tyee salmon, Columbia River salmon, black salmon, chub salmon, hook bill salmon, winter salmon, Spring Salmon, Quinnat Salmon and blackmouth. Chinook Salmon are typically divided into "races" with "spring chinook," "summer chinook" and "fall chinook" being most common. Races are determined by the timing of adult entry into fresh water. A "winter chinook" run is recognized in the Sacramento River.

Coho Salmon:  The Coho salmon (Oncorhynchus kisutch) is a species of anadromous fish in the salmon family. Coho salmon are also known as silver salmon or "silvers."  The traditional range of the coho salmon runs from both sides of the North Pacific ocean, from Hokkaidō, Japan and eastern Russian, around the Bering Sea to mainland Alaska, and south all the way to Monterey Bay, California. Coho salmon have also been introduced in all the Great Lakes, as well as many other landlocked reservoirs throughout the United States.

Fairy Shrimp:  Fairy shrimp (Anostraca) are branchiopods that include brine shrimp. They often appear in vernal pools, pot holes and other ephemeral pools. Although they live in fresh or saltwater, they do not live in oceans or seas. They are well-adapted to living in arid areas where water is present for only part of the year. Their eggs will survive drought for several years and hatch about 30 hours after rains fill the pools where they live.


California Red-Legged Frog:  California red-legged frogs are nearly endemic to California, only leaving the State as they enter extreme northern Baja California. This species occurs most commonly along the Northern and Southern Coast Ranges, and in isolated areas in the foothills of the Sierra Nevada Mountains.

Its back is brown, grey, olive or reddish color with black flecks and dark, irregular, light-centered blotches and is coursly granular. There is a dark mask with a whitish border above the upper jaw, and black and red or yellow mottling in the groin. The lower abdomen and the underside of its hindlegs are normally red.  A characteristic feature of the red-legged frog is its dorsolateral fold, which is visible on both sides of the frog extending roughly from the eye to the "hip." The California red-legged frog was listed as a threatened species by the United States Fish and Wildlife Service in 1996.


Mount Hermon June Beetle:  The Mt. Hermon June beetle is a rare June beetle found in the Santa Cruz Mountains south of San Francisco, California.  This species is threatened by habitat destruction due to sand mining and urban development.  About 60% of its habitat has been loss or disturbed, and much of its remaining habitat is unprotected or privately owned. The US FWS plans to purchase and protect large tracts of sand hill habitat while biologists continuously study the habitat/food requirements and behavior of this species.


San Joaquin Kit Fox:  The San Joaquin Kit Fox (Vulpes macrotis mutica) was formerly common in the San Joaquin Valley of California. Its 1990 population was estimated to be 7,000, and it is now considered endangered. On September 26, 2007, Wildlands, Inc. announced the designation of the 684-acre Deadman Creek Conservation Bank, which is intended specifically to protect habitat of the San Joaquin Kit Fox.


Tadpole Shrimp:  Members of the order Notostraca (colloquially referred to as notostracans, called Triops, tadpole shrimp or shield shrimp) are small crustaceans in the class Branchiopoda. Triops have two internal compound eyes and one naupliar eye in-between, a flattened carapace covering its head and leg-bearing segments of the body. The order contains a single family, with only two extant genera. Their external morphology has apparently not changed since the Triassic appearance of Triops cancriformis around 220 million years ago. Triops cancriformis may therefore be the "oldest living animal species on earth."

Zayante Band-Winged Grasshopper:  The Zayante band-winged grasshopper is found in a small area of the Santa Cruz Mountains known as the Zayante sand hills. This species is found in open sandy areas that are sparsely covered with lotus, herbs, and grasses at the base of pines.  The primary threat to the species is loss of habitat due to human activities and alterations, such as sand mining and urban and agricultural development. Other threats include the introduction of non-native species, pesticides, and over collecting. This species was listed as endangered in 1997.
