Trees in a tropical forest are farther from others of the same species than expected, research finds.

As temperatures increase and prolonged drought continues, a new study of ponderosa pine forests underscores the importance of summer monsoons.

Tree diversity can increase storage of carbon and nitrogen in forest soils and ease the effects of climate change, a new study shows.

Some conifer forests in California are stranded in habitats that are too warm for them. New research digs into how to save "zombie forests."

New research introduces a concept called the "ecosystem wilting point," which explains how whole forests respond to drought.

The availability of trees used for timber in the continental US could decline by as much as 23% by 2100 under more severe climate scenarios.

Geochemical evidence suggests that carbon dioxide levels may have been much lower millions of years before the emergence of large forests.

Animals play a key role in reforestation by carrying a variety of seeds into previously deforested areas, say researchers.

Preserving old-growth trees, which can handle drought better than young ones, may provide a buffer against future climate change.

Voluntary commitments to avoid buying soybeans grown in areas of Brazil that have recently been deforested aren't enough, two studies show.
