A warmer, drier climate is expected is increase the likelihood of larger-scale forest disturbances such as wildfires, insect outbreaks, disease and drought, according to a new study co-authored by a Portland State University professor.

A warmer, drier climate is expected is increase the likelihood of larger-scale forest disturbances such as wildfires, insect outbreaks, disease and drought, according to a new study co-authored by a Portland State University professor.

The study, published Oct. 19 in the journal Nature Communications, sought to provide a more complete snapshot of disturbances in the world's temperate forests by quantifying the size, shape and prevalence of disturbances and understanding their drivers. 

The researchers analyzed 50 protected areas like national parks as well as their immediate surroundings, allowing them to compare disturbances inside protected areas that are more climate-related from those just outside that would also be impacted by human land use.
