This research sheds light on how deer impacts may change with soil pH and suggests that deer management is critical for protecting tree regeneration given current soil conditions.
Mountain laurel, the abundant state flower, had been thought to compete with tree seedlings. But the study did not find that mountain laurel was a significant inhibitor of tree seedlings.
The researchers tested the soil. Nearly all plots in the forests had a pH less than 4 prior to the liming treatment, the result of natural soil acidification and prior acid rain.
