Edward O. Wilson clambered partway down a slope in the Florida Panhandle, aided by a park ranger and trailed by a few dozen scientists, conservationists, and local landowners. The group had gathered in Torreya State Park, a landscape of dazzling botanical diversity along the upper Apalachicola River, as part of a whirlwind two-day meeting early this month to ponder the fate of its most storied tree. As the wind gusted through leafless branches, the lanky, white-haired Wilson, at 88 years of age still one of the most brilliant biologists of his generation, planted a seedling of the Florida torreya, North America’s most endangered conifer.
Wilson first visited the Apalachicola bluffs in 1957, as a self-described “young guy” with a new position at Harvard University, on an ant-collecting trip in Florida. “I came here,” he recounted, “the way you would go to Paris to visit a cathedral. I just had to see the torreya.” The trees had already begun their steep decline.
More than 60 years later Wilson was back. This time he declared the site “is not only a cathedral, but also a battleground at which one of the greatest events in American history will take place” — a turning point, as he sees it, in the planetary struggle to slow biodiversity loss.
Last spring, another “young guy” was at Torreya State Park on a camping trip with his lab. University of Florida forest pathologist Jason Smith “couldn’t believe how much worse the torreyas were” than when he had seen them the year before. “The population was crashing.” Smith, who has reddish brown hair and a bundle of energy, decided to assemble a team to reflect on the meaning of the species’ imminent demise, to catalog the “torreya tree of life” — all living things with which it associates in the wild — and to plan a last-ditch effort to save it.
“This is a now or never moment for the species,” he says.
While the massive wildfires and tree die-offs out West have gotten most of the press in recent years, the Eastern forests are also in crisis. An increasing number of the region’s iconic native trees are plagued by pests and pathogens introduced from abroad. This has researchers scrambling to find genes that can help impart resistance, and to breed them into the ailing trees. Because classical crossbreeding takes decades — perhaps too long for a critically endangered species like the torreya — options once unimaginable as conservation measures are now being considered, including the new group of gene-editing technologies called CRISPR that has taken the biotech world by storm.
The growing forest health crisis is forcing scientists, conservationists, and the public to answer some of conservation biology’s thorniest questions. Will we be able to use biotechnologies on the frontier of plant science to rescue imperiled species? Should we? And when so many species are at risk, does it make sense to go to extraordinary lengths to save a tree like the Florida torreya that has a tiny historical range and no commercial value?

A top federal appeals court has added fuel to a long-running fight over federal protections for the northern spotted owl in California, Oregon and Washington state.
In a unanimous decision Tuesday, the U.S. Court of Appeals for the District of Columbia Circuit ruled that the lumber companies united as the American Forest Resource Council have the legal standing to challenge the owl’s designated “critical habitat.” Federal officials in 2012 designated more than 9.5 million acres in the three states as essential for the owl’s survival.
“The council has demonstrated a substantial probability that the critical habitat designation will cause a decrease in the supply of timber from the designated forest lands,” Judge Brett Kavanaugh wrote, adding that there’s also evidence that “council members will suffer economic harm as a result of the decrease in the timber supply from those forest lands.”
a combination of political instability, government mismanagement, a lack of forest operation controls and a failure to impose punitive penalties on well-known traffickers contributed to what was effectively zero control over the management of precious timber resources in Madagascar between March 2010 to March 2015, according to a new TRAFFIC study released today.
At least 350,000 trees were illegally felled inside protected areas and at least 150,000 tonnes of logs illegally exported to destinations including China, Malaysia and Mauritius over the five-year period, according to the study: Timber Island: The Rosewood and Ebony Trade of Madagascar.
The lack of regulation was compounded by additional factors including widespread poverty, corruption, poor species identification skills at point of harvest and deficient knowledge about timber resources and led to rampant, unregulated felling of precious timber species.
How do you protect some of the most endangered forest habitats in the United States? The answer may lie with a critter that often lives beneath that forest: a burrowing species called the gopher tortoise.
Gopher tortoises, which are listed as threatened by the federal government, are native to the Southeastern United States, where they have made their home in a unique, sandy ecosystem called the longleaf pine forest. These forests, which once covered more than 90 million acres across the Southeast, have all but disappeared. Today, after more than 200 years of development, only about 3 percent of historic longleaf pine forests remain.
Most of the longleaf forest that still stands—including more than 80 percent of gopher tortoise habitat—exists on privately held lands. To help both species, the U.S. Department of Agriculture this month launched a strategy to provide landowners with the tools and resources they need to restore and enhance their pine forests.
World governments currently meeting in Johannesburg have strongly backed the introduction of stronger measures to protect commercially traded timber species.
Delegates to the 17th Conference to the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES CoP17) voted to list the entire Dalbergia genus within Appendix II of the Convention as well as three species of Guibourtia from Central Africa and Pterocarpus erinaceus from West Africa.
The Appendix II listings mean control measures will be put in place to control commercial international trade in the species.
