Abstract

Wildfires can influence the canopy structure of resprouter forests in multiple ways including crown scorching and consumption, tree damage and mortality, and changes in resources available for recovery. Few studies have quantified post-fire changes in the canopy structure of fire-tolerant eucalypt forests, which limits understanding of the extent and persistence of fire effects on ecosystem processes including interactions with environment. In this study, we assess the impacts of a landscape-scale wildfire on the canopy structure of fire-tolerant eucalypt forests in temperate Australia using metrics derived from airborne lidar data. Our assessment, made seven years after the wildfire, encomp..
