Long-term trends in forest regeneration across drought and salinity gradients in the northern Gulf Coast- Beth Middleton

Relict forests are becoming more common as as climates become hotter, drier and more saline. The first sign of threat to these forests is a chronic lack of seedling and sapling recruitment. This project will help pinpoint forests at risk to help in future management.
