As we agonize over ongoing extinctions, we also need to remember how far and how quickly we鈥檝e come in avoiding them, and how we鈥檝e saved species once on the brink such as the , , , , , American alligator, fisher, gray wolf, and pronghorn, to mention just a few.
Northern Spotted Owl
Consider the protracted spotted-owl wars in the Pacific Northwest. The bird is still declining, politicians are still bloviating, the timber cartel is still suing. But what鈥檚 so encouraging about the wars is that they鈥檙e happening. Moreover, the bird may now have a future. In June 2011 the U.S. Fish and Wildlife Service hatched its revised recovery plan, and in November 2012 it nearly doubled critical habitat.
While the plan hasn鈥檛 inspired environmentalists to handsprings, director Shawn Cantrell says this: 鈥淚t鈥檚 telling that, unlike the other plans, no [green] group has challenged this one in court. We鈥檇 like to see some things added and changed, but overall we鈥檙e pleased. We鈥檙e taking two steps forward and one step back, but under the previous administration it was one step forward and five steps back. Now there鈥檚 a willingness to let career biologists make the decisions.鈥
Henslow鈥檚 Sparrow
When we 鈥減icked鈥 bison off the landscape we confirmed John Muir鈥檚 maxim. It turns out they鈥檙e 鈥渉itched鈥 to . Originally, the bird was restricted to prairie. Then, with the clearing of land, it expanded east. But mechanized agriculture, forest succession, and development of farmland soon sent it into steep decline. When the conventional management practice of burning prairies wasn鈥檛 producing the desired results, researchers tried light mowing that simulated grazing by bison. Unlike cattle, bison maintained prairie habitat by feeding casually and moving on. Bison reintroduction has even been part of Henslow鈥檚 sparrow management, and the birds have responded well.
Eminent field guide editor, author, and 探花精选 field editor Kenn Kaufman warns that if no one pays attention, Henslow鈥檚 sparrows could be in lots bigger trouble. Happily, we are paying attention. 鈥淲ith better survey work we鈥檝e found thriving populations in places they weren鈥檛 traditionally known,鈥 he says. 鈥淚 was more concerned about these birds 10 years ago than I am now.鈥
Bobwhite Quail
鈥攁 cooperative venture by the federal Farm Service Agency, the U.S. Fish and Wildlife Service, 32 state fish and wildlife agencies, sportsmen鈥檚 groups, and landowners鈥攊s reversing the decline of bobwhite quail (from an estimated 31 million 40 years ago to about 5.5 million today). The main work will be repairing degraded habitat and limiting stocking of the game-farm birds that have bred hardiness out of wild populations. The herculean effort does bring our priorities into question. (If Florida grasshopper sparrows were bigger, held for pointing dogs, and went well with white wine, they鈥檇 be doing fine.) Still, it鈥檚 a model for what needs to be done for all imperiled species, and it teaches that Muir鈥檚 maxim works just as well in reverse: When we replace a single thing in nature we find it hitched to everything else. In the process of recovering bobwhites, we鈥檙e recovering Henslow鈥檚 sparrows along with hundreds of other grassland and prairie parts.
