This is Your Brain on Nature

But how can we determine how much of this relationship is causal when there could be other reasons for correlation? Well, a new study released from researchers at Heriot-Watt University in Edinburgh and the University of Edinburgh published in the British Journal of Science has begun answering that question with some pretty high-tech tools.

The 12 study participants were given portable electroencephalograms (EEGs) called Emotiv EPOC to wear under hats against their scalps. The EEGs measured brain waves and sent data wirelessly to a laptop in the participant’s backpack. And here I thought Google glasses sounded high-tech! The p... (Read More)




Backyard Biodiversity

“Conservation is about waiting for a long time,” says Dan Ashe, director of the U.S. Fish and Wildlife Service. So, in a society that wants speed and short waits, Ashe explains, conservation too often gets neglected.

Ashe was one of four plenary speakers at the 78th North American Wildlife and Natural Resources Conference, a week-long event coordinated and administered by the Wildlife Management Institute (WMI). Held in Arlington this week, the annual conference brings together environmentally-minded scientists, administrators, managers and educators from organizations across the country, ... (Read More)




Have You Hugged a Tree Lately?

That’s the question our director of urban forests, Melinda Housholder, asks in a guest blog on the National Wildlife Federation’s Wildlife Promises blog.

To quote Melinda:

When I did field work with the National Park Service a few years ago along the National Mall, I hugged trees on a daily basis. Well, by that I mean, when checking for the DBH (diameter at breast height) of specific trees, I often had my arms wrapped around trees. Not in a uniform, I am sure it looked like I was just a visitor to D.C., taking some time out of my day to embrace the tree for a moment of gratitude. And, well, why shouldn’t I?... (Read More)




A Menace to Maples

ALB is a black beetle between one and one-and-a-half inches long, with white spots and — as its name implies — two antennae that are even longer than its body. In addition to recognizing the beetles themselves, you can also spot them by signs of occupation on the tree. In early autumn, females dig out oval depressions in which to lay their eggs. When the larvae hatch, they burrow into the wood to feed and grow through the winter. In spring, they emerge as adult beetles, leaving tell-tale, dime-sized holes behind them.

The maple industry, in particular, is worried. This $41 million industry has already been affected in Ma... (Read More)




Urban Forests and Ecosystem Services Research

The Einstein Memorial on the grounds of the National Academy of Sciences, Washington, D.C.

Last week, I participated in a workshop titled “Urban Forestry: Toward an Ecosystem Services Research Agenda” at the National Academy of Sciences in Washington, D.C. The workshop brought together more than 100 participants, and many more tuned-in via webinar. What a great turn out!

With interesting presentations, discussions and networking opportunities, I was excited to participate and hone in on the workshop’s key objectives to:

Explore the role of trees within the greater urban ecosystem and the linkages/trade-offs among different types of ecosystem services within this larger context. Review our current understa... (Read More)
