Research examines how fire-caused injuries affect tree growth and drought vulnerability in conifer forests, indicating management implications.

The aim is to evaluate how fire injuries influence tree growth and drought sensitivity in conifer species post-fire.
Monitored Douglas-fir and ponderosa pine before and after prescribed burns.
Compared burned trees with unburned control sites.
Implemented rainfall exclusion to assess drought effects post-fire.
Measured changes in tree water status and growth over time.
Burned trees exhibited higher water stress compared to unburned controls during the first 1-2 years post-fire.
Post-fire drought intensified water stress at one study site.
Radial growth showed a temporary decrease linked to levels of crown scorch sustained by the tree.
Growth and water status may recover over time but at varying rates between sites.

Reed et al. (2026) studied this question.
