Researchers have been modeling effects of the plant pathogen Phytophthora ramorum on coastal forests in California and Oregon since it arrived on the West Coast 3 decades ago.

Tropical Forests Are Losing Their Ability to Soak Up Carbon
The forests could switch from a carbon sink to a carbon source by the mid-2030s.
Forests Respond to Volcanic Emissions
Researchers propose using volcanoes to study forests and forests to study volcanoes.
Hurricanes Hit Puerto Rico’s Mangroves Harder Than Florida’s
The scale and pattern of damage to the Puerto Rican forests suggest a complex interplay between wind, land, and sea.
How Forest Structure Influences the Water Cycle
New research looks at how changes in the arrangement of trees and canopy thickness influence the transport of water from the land surface to the atmosphere.
Congo Rain Forest Endures a Longer Dry Season
The forest’s dry season has been starting earlier and ending later for decades, making parts of it vulnerable to incursions by drought-resistant ecosystems.
Insect Infestations Alter Forest Carbon Cycle
A hemlock woolly adelgid outbreak in southern Appalachia prompted a transformation in where the forest stores carbon.
Why Mountainous Upland Forests Emit So Much Methane
New research suggests that moist tree heartwood produces methane and emits the greenhouse gas to the atmosphere.
How the Micrometeorology of Alpine Forests Affects Snowmelt
A field study in the Swiss Alps showed considerable spatial and temporal variability in forest air and surface temperatures, with implications for snowmelt models.
Bark Beetles Cause Big Tree Die-Offs, but Streams Flow Steadily
Recent beetle epidemics have driven tree die-offs across North America, and previous studies predicted an increase in annual streamflow would follow—but a new study shows this may not be the case.
