Effectiveness of herbivore exclusion fences for plant conservation depends on management strategy and landscape context

open access: yesConservation Science and Practice, Volume 7, Issue 12, December 2025.
Fences are widely used to restrict or reduce grazing pressure on endangered plant species or communities, and to ultimately ensure their viability. Here, we evaluate what factors determine their effectiveness at a regional scale by assessing ungulate detection (presence/absence) within exclosures and discuss its ecological and conservation implications.
