Scheduling Revegetation for Biodiversity: Strategies for Effective Planning

This document outlines strategies for scheduling revegetation efforts aimed at enhancing biodiversity. It addresses the challenges posed by limited resources—including space, time, and budget—while considering multiple objectives such as the restoration of various taxa including vegetation, birds, and mammals. The authors discuss the importance of local habitat conditions, ecological vegetation classes, and the influences of climate change. By integrating maps, prioritization measures, and cost analyses, the study offers a framework for effective, large-scale revegetation planning that supports ecological balance and restoration goals.

Presentation Transcript

  1. Where and when to revegetate? scheduling revegetation for biodiversity Jim Thomson, Peter Vesk, Atte Moilanen, Ralph Mac Nally, Andrew Bennett

  2. Where and when to revegetate? • Limited resources • space, time and money • Multiple objectives • Biodiversity • Multiple taxa (e.g. vegetation types, birds, mammals, etc) • Water • Surface & groundwater • Carbon

  3. Pre-European Vegetation 1750 Ecological Vegetation Class (EVC)

  4. Remnant Vegetation Current Ecological Vegetation Class (EVC)

  32. “Restoration Zonation” • large-scale (fine-resolution), long-term revegetation planning • Multiple taxa, many species • Local habitat and connectivity requirements • costs / constraints • other objectives…

  33. Extensions • spatially-dependent growth rates • climate change (temporally-dependent H) • additional objectives (taxa, carbon, water) • more realistic costs • reveg methods (spatially-dependent)
