The large black bear in this video was observed ambling around a Monrovia, California neighborhood last Friday morning. The bear walked through residential lawns, driveways and rested in a nearby alley. Read the rest
Last month, the "Wizard Rock," an iconic 1-ton boulder, mysteriously vanished without a trace from Arizona's Prescott National Forest. It was the third boulder disappearance in the region over the last few months. Read the rest
Casey Hathaway, age 3, was lost for three days in the woods of Craven County, North Carolina before police found him alive and well. He had survived pouring rain and near-freezing temperatures. According to Hathaway, a bear looked after him in the forest.
"He made a comment about having a friend while he was in the woods -- his friend was a bear," Maj. David McFadyen of the Craven County Sheriff's Office told CNN. "In the emergency room he started talking about what happened in the woods and he said he had a friend that was a bear with him while he was in the woods."
It is true that there are bears in those woods. Read the rest
Climate change is why California is burning, and thousands of its citizens displaced, injured, or killed by the wildfires that spread with never-before-seen intensity. Read the rest

An astronaut on the International Space Station snapped this striking photo last month of forest land adjacent to the Priest River in northern Idaho. From NASA:
The squares in this landscape checkerboard appear to be the result of forest management. Similar patterns originated in the 1800s, when alternate parcels of land were granted by the U.S. government to railroads such as the Northern Pacific. Many parcels in the Pacific Northwest were later sold off and harvested for timber.
The land shown here is now managed for wildlife and for timber harvesting. The white patches reflect areas with younger, smaller trees, where winter snow cover shows up brightly to the astronauts. Dark green-brown squares are parcels of denser, intact forest. The checkerboard is used as a method of maintaining the sustainability of forested tracts while still enabling a harvest of trees.
This deforestation machine slices and plucks trees at their base and then wipes off all the branches and foliage in just a few seconds. (Thanks, Dustin Hosteler!)
Fun little short documentary from the Atlantic on YouTube, in which you meet people who build, live in, and love treehouses. Gotta be honest here, this is very much a lifelong passion and dream of mine.
By now, many of you are probably aware that human behavior is one of the key factors behind some of the massive forest fires we've seen in recent years. The basic story goes like this: Under a natural cycle, periodic small fires sweep through forests, burning through small trees and dry brush. But if you prevent those fires from happening—as humans have done for around a century at this point—all that highly flammable stuff builds up. In the end, you're left with a giant tinderbox of a forest. The next time a fire does happen there, it's almost guaranteed to be much, much bigger and more destructive than the natural fires that forest is adapted to.
NPR has a very nice story about the science and history behind this problem, which forest fire experts call "The Smokey Bear Effect", after the cartoon Ursus the U.S. Forest Service has long used as part of its fire prevention campaign.
Its ill-advised fire prevention campaign.

"The irony here is that the argument for setting these areas aside as national forests and parks was, to a large extent, to protect them from fire," Pyne says. "Instead, over time they became the major habitat for free-burning fire."
So instead of a few dozen trees per acre, the Southwestern mountains of New Mexico, Arizona, Colorado and Utah are now choked with trees of all sizes, and grass and shrubs.
I'm currently attending the Marine Biological Laboratory's 10-day science journalism fellowship. As part of that, I get to do some hands-on science experiments and get a better perspective on how the work of science is done and how data is collected. Along with five other fellows, I spent last weekend collecting A LOT of data in Massachusetts' Harvard Forest—3,500 acres of extremely well-documented wilderness.
All this week, I'll be posting some of the highlights from my trip—videos and photos that will introduce you to the Harvard Forest, how science is done in the field, and to some of the key ideas that I'm learning during my time here.
This will be the central access point for all those posts. Check back every day to see what's new.

Jared Keller on the new science of forestry robotics: "The vast majority of forests are destroyed by wild forest fires, and current methods of sylvan vigilance -- mainly those involved individual personnel on foot patrol -- are grossly inefficient in identifying emerging threats. Read the rest
One of the interesting things about the global carbon dioxide and climate systems is the concept of feedback loops. You already know that as atmospheric concentrations of carbon dioxide go up (and with them, the global average temperature) you get lots of different kinds of changes all over the place. For instance, mountain pine forests start experiencing warmer winters and smaller snowpacks. But, as those changes happen, they can actually trigger secondary effects that contribute to, and increase the rate of, climate change.
In this video, you'll learn about how warmer temperatures and lower snowpacks are contributing to the spread of massive pine beetle infestations across the western United States. This is more than just inconvenient. The pine beetles can quickly kill huge amounts of trees, raising the risk of property-destroying forest fires and razing whole ecosystems. And, as the trees die en masse, forests that were once carbon sinks (absorbing more carbon dioxide than they released) become emitters—adding more carbon dioxide to the atmosphere.
