Quantifying Trophic Rewilding: Functional Response Metrics for Released Herbivores
This comprehensive guide delves into the quantitative frameworks essential for measuring functional responses in herbivores released during trophic rewilding projects. Designed for experienced practitioners, conservation biologists, and restoration ecologists, it moves beyond conceptual discussions to provide actionable metrics, analytical workflows, and decision-making tools. Topics include defining functional response curves, selecting appropriate mathematical models (e.g., Holling types, ratio-dependent models), designing field experiments, deploying GPS and accelerometer biologgers, and integrating vegetation transect data. The guide also addresses common pitfalls such as pseudo-replication, handling missing data, and accounting for seasonal diet shifts. With comparative tables, step-by-step protocols, and risk mitigation strategies, this resource equips readers to robustly quantify grazing impacts, predict ecosystem effects, and adaptively manage rewilding outcomes. The editorial perspective reflects current best practices as of May 2026, emphasizing evidence-based approaches without fabricated case studies.
