Use of LiDAR to examine habitat selection by incubating female wild turkeys in South Carolina

open access: yesWildlife Society Bulletin, Volume 49, Issue S1, December 2025.
We evaluated how spatially explicit LiDAR‐derived estimates of forest structure and topographical features influenced selection by female eastern wild turkeys (Meleagris gallopavo silvestris) during the incubation period. Female wild turkeys selected for incubation recess locations in pine (Pinus spp.) forests with an average basal area of ~14m2/ha and
