A Plan for New York City’s Forests. Yes, Forests.

By James Barron

The city has 10,542 acres of forests. The Natural Areas Conservancy, which says they are at a tipping point, is thinking about how to care for them.

Sarah Charlop-Powers was comparing New York City’s forests to its subways.

The city has more than 840 miles of tracks for one. It has 10,542 acres of the other, about half as much as the Congaree Swamp in South Carolina, a small national park with an old-growth forest and, according to the website I Love National Parks, “more bugs than you can imagine.”

No doubt there are many bugs in New York’s forests, even cockroaches that have yet to find their way to somebody’s basement or bathtub. But Ms. Charlop-Powers, the executive director of a Manhattan-based nonprofit group called the Natural Areas Conservancy, is not focused on them. She sees the trees — and the forest. Most of the city’s forest is deep in parks, and on the worry spectrum, she is “concerned” about them.

“The situation is not dissimilar to the subways, in that we’re at a crucial moment,” she said.

Fortunately, urban forests appear to be at the point the subways reached decades ago, before transit policymakers decided that maintenance could be deferred.

For Endangered Florida Tree, How Far to Go to Save a Species?

By Janet Marinelli
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?

Introducing the National Extension Forestry & Wood Products Directory

We are pleased to introduce a new way for Extension agents across the United States to connect with each other: the Extension Forestry and Wood Products Directory, a national network of over 300 extension forestry and wood products specialists, educators, and leaders. Collectively, these personnel cover 48 areas of forestry and wood products specialties and 16 areas of extension program development, delivery, and evaluation.

This directory has been compiled to identify Extension personnel and their specialties, to better serve those seeking information about forests and wood products, and to facilitate multi-state, regional, and national program collaborations. Users are able to search the directory by name, institution, location, and specialty, and directory information can be exported into various formats for later reference.

We hope that this resource encourages collaboration, partnership, and innovation between Extension personnel nationally and across regions. Please let us know if you have any comments or suggestions.

If you’d like to have your information included in the directory, please submit your info. Contact Eric Norland (enorland@nifa.usda.gov) if you have any questions regarding the directory.

Pine beetles from Jasper National Park now infesting commercial forest

By Bob Weber
A massive and uncontrollable buildup of mountain pine beetles in Jasper National Park is starting to explode into commercially valuable forests along its boundaries.

Foresters along the park’s edge have seen a tenfold increase in beetle infestation in just months, and some scientists wonder if Parks Canada could have done more to control the invasion a few years ago.

“They decided to consider the pine beetle a ‘native disturbance agent,”‘ said Allan Carroll, who has studied the beetles since the late 1990s and directs the University of British Columbia’s Forest Science program. “In other words, Jasper was not intending to do much about it.”

No end to pine beetle battle in Alberta, experts say
In an emailed statement, Parks Canada said it has had a beetle management plan for the park since 2015 that includes prescribed burns and tree removal.

Too little, too late, said Carroll.

“Just that hesitation intrinsic to producing a management plan precluded any effective outcomes.”

Vikings Razed the Forests. Can Iceland Regrow Them?

By Henry Fountain
The country lost most of its trees long ago. Despite years of replanting, it isn’t making much progress.

The country lost most of its trees more than a thousand years ago, when Viking settlers took their axes to the forests that covered one-quarter of the countryside. Now Icelanders would like to get some of those forests back, to improve and stabilize the country’s harsh soils, help agriculture and fight climate change.

But restoring even a portion of Iceland’s once-vast forests is a slow and seemingly endless task. Despite the planting of three million or more trees in recent years, the amount of land that is covered in forest — estimated at about 1 percent at the turn of the 20th century, when reforestation was made a priority — has barely increased.

There’s a Climate Bomb Under Your Feet

By Eric Roston
Soil locks away carbon just as the oceans do. But that lock is getting picked as the atmosphere warms and development accelerates.

Long before most people ever heard of climate change, scientists divided a patch of Harvard University-owned forest in central Massachusetts into 18 identical 6-meter by 6-meter squares. A canopy of red maple and black oak trees hangs there, looming above the same stony soil tilled by colonial farmers. Rich in organic material, it was exactly what the researchers were looking for.

They broke the land up into six blocks of three squares each. In every block, one square was left alone, one was threaded with heating cables that elevated its temperature 9 degrees Fahrenheit (5 degrees Celsius) above the surrounding area. The third square was threaded with cables but never turned on, as a control.

That was 26 years ago. The purpose was to measure how carbon dioxide may escape from the earth as the atmosphere warms. What they found, published yesterday in the journal Science, may mean the accelerating catastrophe of global warming has been fueled in part by warm dirt. As the Earth heats up, microbes in the soil accelerate the breakdown of organic materials and move on to others that may have once been ignored, each time releasing carbon dioxide into the atmosphere.

Managing for Healthy, Diverse Forests

Healthy forests, just like healthy human populations, are sustained by a diversity of ages and types. In many parts of the United States, forests are becoming largely homogeneous, and in places like the Appalachian Mountains, young forest and mature, old growth forests are in short supply.

A lack of diverse forests has negative impacts on wildlife and the economy, as different age classes support higher biodiversity and provide a more sustainable source of income for forest landowners. Through the use of sustainable forestry practices, forest landowners are able to compensate for lack of natural disturbance.

USDA’s Natural Resources Conservation Service (NRCS) recommends a number of sustainable forestry practices to forest landowners. These practices provide landowners with a number of choices, depending on the land and a landowner’s goals.

Manage forests, or watch them burn

For those who had not witnessed the blast-furnace heat and the eye-stinging smoke of a wildfire along with the mass destruction of timber, homes, businesses and wildlife, last week was a learning experience.

Nearly every corner of the West was on fire. From Arizona to Washington state and from California to Montana, 65 active fires were burning 2.83 million acres as of late last week. Those numbers include only the fires that were 10,000 acres or larger. The average size of those fires was 43,556 acres

American Trees Are Moving West, and No One Knows Why


By Robinson Meyer
As the consequences of climate change strike across the United States, ecologists have a guiding principle about how they think plants will respond. Cold-adapted plants will survive if they move “up”—that is, as they move further north (away from the tropics) and higher in elevation (away from the warm ground).

A new survey of how tree populations have shifted over the past three decades finds that this effect is already in action. But there’s a twist: Even more than moving poleward, trees are moving west.

About three-quarters of tree species common to eastern American forests—including white oaks, sugar maples, and American hollies—have shifted their population center west since 1980. More than half of the species studied also moved northward during the same period.

These results, among the first to use empirical data to look at how climate change is shaping eastern forests, were published in Science Advances on Wednesday.
