Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Use prescribed burning to control trees One randomized, replicated, controlled, before-and-after trial in the USA found that burning to control trees did not change cover of two of three grass species. One randomized, controlled study in Italy found that prescribed burning to control trees reduced cover of common heather, increased cover of purple moor grass, and had mixed effects on the basal area of trees.

However, it did not alter the cover of purple moor grass.

One randomized, replicated, controlled study in the UK found that prescribed burning initially reduced vegetation height, but this recovered over time.

One randomized, replicated, controlled study in the UK found that soil disturbance increased the abundance or species richness of specialist and generalist plant species.
