The Zanzibar Red Colobus is endemic to Tanzania.
Tanzania faces the challenge of conserving forests in a developing country with a rapidly expanding population.
The 2016 Maple fire (photographed in July 2017) reburned young forests that had regenerated after the 1988 Yellowstone fires. More frequent high-severity fires are expected in the future as climate warms, which may change patterns of forest recovery.
Huge fires roared through Yellowstone National Park in the summer of 1988, scorching one-third of the park. Since then the park has been a valuable lab for studying how forests recover from fires.

The Trump administration wants to step up logging, saying it will benefit wildlife by reducing forest fire risks. But wildfires create habitat for threatened Spotted Owls and many other species.
Fighting wildfires with air tankers, like this one dropping fire retardant on the Willow Fire in California on September 2, 2015, is expensive and not always effective.
A perfect storm of climate, forestry, development and fire management trends are driving up the costs of fighting wildfires.
Wildland firefighters, like this crew heading into New Mexico’s Gila National Forest, in 2012, are equipped and operate differently from urban firefighters.

A historian of wildfires explains the difference between urban and rural fire cultures, and what it means for protecting communities in fire-prone rural areas.
There should be caution in jumping on the “forests are always better” bandwagon.
It's important to be wary of planting trees in places where none exist, or where there are significant water constraints.

The illegal timber trade is a huge global business worth up to US$150 billion yearly. One way to curb it is by convincing consumers in wealthy countries that buying contraband wood products is wrong.
Europe loses as many trees to storms each year as Poland produces in timber. Until now, the models for predicting which trees are at risk have not been good enough.
New research shows that fire follows fire in the Australian Alps, and old-growth forests are less flammable.

On April 5, 1933, President Franklin Roosevelt created the Civilian Conservation Corps, a massive relief program that paid young men to plant trees and build parks across the nation. It was money well spent.
Current protections for native forests are hopelessly out of date.
Agreements between the Commonwealth and state governments that protect native forests are based on hopelessly out-of-date information. It's a huge mistake to renew them without assessment.
It’s as if Socrates’ remark that 'the trees teach me nothing' is very much still the attitude today.

How do you determine the financial benefit of cutting a tree down, versus leaving it standing? Environmental accounting offers some insight.
A fire recently tore through an Italian memorial to Mussolini made of trees.
A forest that is also a disturbing memorial to Mussolini recently burned down.
Replanting forests in China is a great initiative but it can also prove to be disastrous for water management.
China has successfully implemented afforestation to counter desertification. But, today, it faces another risk: its waters are declining.
A brown bear snags a sockeye salmon in Alaska. In warm years, red elderberries ripen early and Kodiak bears leave streams full of salmon to eat them.
Climate change is making berries ripen early in Kodiak, Alaska, luring bears away from eating salmon. This shift may not hurt the bears, but could have far-reaching impacts on surrounding forests.
Leaf sizes vary according to a complex mix of temperature and water.
Some leaves are millimetres across, and others are a metre square. An international study has found the essential factors controlling leaf variations.

Indonesian peatlands are important to many people: farmers, bureaucrats, businesspeople, and conservationists. But preserving this value for everyone will mean listening to everyone's concerns.
