Ever since the Sierra Club’s David Brower first brought pristine wilderness into the living rooms of armchair hikers in the 1960s with the Exhibit Format series, conservationists have enlisted the power of photography to argue their cause. From the beginning, the books struck a chord. The Club made $10 million in just nine years from the series. As John McPhee reported in his classic portrait of Brower, Encounters with the Archdruid, even Brower was “surprised to find that people were willing to pay that much for beauty.”
Brower, who died in 2000, believed that if you wanted people to support wilderness conservation, you had to show them what it was like. ARKive, a digital multimedia repository initiative launched in 2003 by the nonprofit charity Wildscreen, applies the same rationale to wildlife conservation with a goal that would have impressed even David Brower: create a multimedia record of all life on Earth.
Using audio, photos, and film, the project brings species iconic and obscure to the public eye, and includes details about habitat, biology, range, threats, and more based on recent research. Their mission--to use the power of wildlife imagery to promote conservation of the world's threatened species--takes on even more urgency, as most scientists agree we've entered the Sixth Great Extinction. In keeping with their mission, curators started with species most at risk of extinction. Unfortunately, that’s a depressingly long list: close to 20,000 species are on the International Union for Conservation of Nature’s Red List of Threatened Species.
Curators hope their digital archive will help educators, researchers, and anyone who cares about biodiversity raise awareness about the nature and value of conserving threatened plants and animals and the habitat they need to survive. Most any of these materials can be used without restriction in classrooms or at home, though copyright and licensing restrictions limit broader use. (Contact ARKive for more information.)
You can find a number of species that live in the Bay Area, as well as farther afield in California in the ARKive database. Here’s a brief roundup:
A new study released last month found that the recovery of the critically endangered California condor, long thought to be one of the West’s greatest conservation successes, may be at far greater risk from lead poisoning than previously thought. North America’s largest bird hovered at extinction’s door in 1982, when just 22 birds survived. As of 2010, the population numbered 400, but ongoing poisoning from lead ammunition raises serious questions about the species’ ability to survive in a landscape strewn with lead-tainted carcasses. As the authors noted in the study, “by any measure, the lead poisoning rates in condors are of epidemic proportions and require substantial effort to mitigate.”
Also known as the Pacific Pond Turtle, this medium-sized terrapin can live up to 40 years and ranges from Baja California to Washington State, where it’s listed as endangered. The species is most abundant between southern Oregon and Northern California. As the name implies, these turtles are found in ponds, as well as in rivers, streams, creeks, and marshes. I often see some basking on a log in Tilden’s Jewel Lake. Once poached for the pet trade, turtles now struggle to maintain viable populations in dwindling habitat as agriculture claims their wetlands and diverts water.
A large, stocky salamander with a built-in smile, the California tiger salamander once lived throughout the San Francisco Peninsula, but now appears restricted to a small population on the Stanford University campus. Distinct populations of the species are listed as threatened in Santa Barbara and Central California and endangered in Sonoma. Juveniles live in vegetation around seasonal pools in savannah and grasslands while adults, not known for their digging skills, take advantage of burrows excavated by ground squirrels and the Bota’s pocket gopher.
This slow-moving, cave-loving shark lives among rocky reefs and kelp forests off the shore of California, from Monterey south to Baja. Some say its oddly shaped muzzle looks like a pig’s snout (my husband thinks it looks like Cecil the Sea-Sick Sea Serpent) but I think it looks more like a deformed cow’s nose. Horn sharks aren’t targeted by commercial fisheries but can end up in nets as incidental bycatch. Not enough data exists for the IUCN to evaluate their conservation status.
