It’s a cool 37 degrees Fahrenheit as Alex Royo and I step out of the Forest Service truck and on to the muddy forest road. With the meteorologist calling for sun and a high of 66 degrees by lunchtime, I am already faced with the day’s toughest decision – do I keep my warm jacket on or leave it in the truck? Either way, half of my 3.5-mile hike is going to be uncomfortable. A quick glance at Alex reveals that he has opted to leave his jacket behind. As we walk into the forest, I can’t help but notice the contrast of colorful spring beauties and trout lilies against the dull brown forest floor. And already, there is the object of my hike — deer pellets. To find pellets so early in the day one has to wonder, just how many deer are out here?
That’s the question that vexes hunters, scientists, and land managers throughout Pennsylvania and beyond. Each and every spring, a small army of individuals from the USDA Forest Service’s Northern Research Station, the Allegheny National Forest, multiple private land managing partners, and volunteers hike hundreds of miles of Pennsylvania’s forests to help determine how many deer the forest holds by counting the most visible part of a deer – deer pellets, which is the nicest term for deer waste.

For young scientists, the years between completing a dissertation and becoming established in your field of research is sometimes an isolating time. The scholarly support of coursework is behind you just at the moment when you have refined your area of expertise. As a research social scientist with the U.S. Forest Service’s New York City Urban Field Station, I wanted to help bridge that gap by fostering a network of young scholars and engaging them in New York City as a living laboratory for urban research.
For three days, the Urban Field Station, located at Fort Totten in Queens, New York City, served as a home base for scientists participating in a workshop titled, “Urban Natures: Engaging Social Science Perspectives.” The workshop was a rare opportunity for Ph.D. candidates and early-career faculty members in disciplines including geography, environmental psychology, natural resource management, and environmental studies, to explore the connections between research and practice in social-ecological systems in a peer-to-peer setting.

Several hundred non-native forest insect species have become established in the U.S. Recent arrivals, such as this adult Asian longhorned beetle, have killed millions of trees and altered urban landscapes in the Northeast and Midwest.

Wood makes great packaging material—it’s inexpensive, abundant and versatile—but there’s one drawback: destructive forest pests stowaway in the pallets, crates and dunnage (wood used to brace cargo) used in international shipping. Over many years, international trade has resulted in the inadvertent introduction of many non-native wood-feeding pests and plant pathogens in the U.S. and throughout the world. Some of these non-native insects, including the emerald ash borer and the Asian longhorned beetle, have become highly invasive and caused serious environmental and economic impacts.
But an international standard for wood packaging material is slowing the inadvertent export of invasive bark- and wood-boring insects, according to a study conducted by Robert Haack, a research entomologist with the Forest Service’s Northern Research Station in Lansing, Mich., and a team of scientists. Researchers found as much as a 52 percent drop in infestation rates in the U.S., where the standard was implemented in three phases between 2005 and 2006. The study was published May 14 in the journal PLOS ONE. Read more »
Bats like this northern long-eared bat are important to agricultural and forest ecosystems and are a significant force in keeping insect populations in check. (U.S. Forest Service/Sybill Amelon)
Sybill Amelon is trying to repair the damage Bram Stoker did to bats’ public image.
A research wildlife biologist with the U.S. Forest Service’s Northern Research Station in Columbia, Mo., Amelon has introduced bats to more than 20,000 primary, secondary and college students and teachers. Over the past 20 years, she has explained bat biology and lifecycles to master naturalist classes, Audubon clubs, garden clubs and native plant societies. Through her research and conservation efforts, she has raised awareness about bat species, while inspiring people to save them.
Amelon’s work was recently recognized with a regional Gifford Pinchot Excellence in Interpretation and Conservation Education Award, a national accolade given to Forest Service employees for achievement in environmental interpretation and conservation education. The annual award is named in honor of the first Forest Service chief. Read more »

Northern Research Station scientist Laura Kenefic resists the temptation to stick with people she knows at scientific gatherings, and her discipline is paying dividends for northern white-cedar.
Attending a forestry conference a decade ago, Kenefic joined a table of strangers that included Jean-Claude Ruel, a Canadian scientist who, it turned out, was looking for long-term data on northern white-cedar. A research forester at the Penobscot Experimental Forest north of Bangor, Maine, Kenefic happens to work at one of the few places in the country with more than half a century of data on the species. Their collaboration quickly grew to include scientists from universities, industry, the U.S. Forest Service and the Canadian Forest Service who are all interested in northern white-cedar. Meetings, dinners and a few adventures in the course of research aimed at addressing the tree’s slow growth and sparse regeneration gave the group of scientists an atmosphere that felt unique to its members. “It seemed more like a club than a scientific working group,” Kenefic said. “We became the Cedar Club.” Read more »
Although birch trees can’t literally walk, warming temperatures are causing a gradual migration of these and other tree and plant species to northern or higher elevation climates. USDA photo.
With large areas of our planet heating up because of climate change, some trees (and plants) are pulling up roots and heading north, to higher elevations and to cooling climes—well, sort of.
A U.S. Forest Service-led study suggests there are a few dozen tree species in the eastern U.S. that are moving north at an unexpected rate.
“For some plants and trees, moving north is real and their only chance for survival,” said Chris Woodall, a research forester for Northern Research Station and the study’s author. “Our study confirms a link between global warming and forest migration. It’s no longer conjecture.” Read more »
