This paper investigates the impact of long-term fire suppression on the drought sensitivity of mixed-conifer forests in the Western United States. The study utilizes tree-ring analysis of stable carbon isotopes to demonstrate that the exclusion of frequent, low-severity wildfires has led to overcrowded forest stands. This increased density results in heightened competition for water and nutrients among trees, making them more susceptible to drought stress, insect outbreaks, and disease compared to historically open forests maintained by fire. The findings emphasize the importance of reintroducing fire and managing stand density for forest restoration and increasing resilience to future climate conditions.
