  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)

  5. Woodland Birds Mac Nally et al. 2009. Diversity & Distributions

  13. Prioritization • Multiple habitat maps for each bird species • 5 x 62 bird maps (20, 40, 60, 80, 140 years) • species-specific landscape context functions (BQP) • 70 EVC maps (1750 extents) • Cost layer (value agricultural output)

  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)
