How resilient are southwestern ponderosa pine forests after crown fires?

Melissa Savage, Joy Nystrom Mast


Summary - what did the authors do and why?

The authors looked at the regeneration of ponderosa pine forests after ten high-severity crown fires that occurred from 1948 to 1977.

Publication findings:

The authors found that in historically low-severity, frequent-?re forests, stand replacing ?re can result in conversion to altered species composition and structure of stands either toward even-aged cohorts of ponderosa pine or to novel vegetation communities through regeneration failure or due to changes in fire regimes which may be exacerbated by climate change and/or extreme weather events.
