P3-A3 Herbivore and browsing management

Managing herbivore pressure is important for successful forest regeneration and maintaining desired tree species composition. Where browsing pressure is high, measures such as regulating ungulate populations or protecting regeneration may be required.

Introduction

Herbivore pressure refers to the impact of browsing by wild ungulates, such as deer, on forest regeneration. Excessive browsing can reduce seedling survival and growth, alter tree species composition, and compromise forest resilience by preventing the successful recruitment of palatable tree species. Monitoring browsing intensity and regeneration provides an early indication of whether herbivore populations are compatible with forest management objectives. Where browsing pressure is high, active management such as regulating ungulate populations through hunting or protecting regeneration with fencing or other physical measures may be required.
