Brief recap

  • Transform 14% of Denmark from agriculture to nature
  • Maximize biodiversity and contiguity of nature areas
  • At least 100,000 hectares of new forest promised Only in carbon
  • At least 70,000 hectares of wet areas in high carbon 6% bellow only in carbon

Maximize Carbon

  • Projected Aboveground carbon

Biodiversity

Plant richness

  • Based on Ellenberg values and presences

Phylogenetic diversity

Rarity

Runs

  • Only biodiversity free
  • Only biodiversity Contrained to already selected areas
  • Biodiversity + Carbon free
  • Biodiversity + Carbon Constrained

Maximize biodiversity

  • Species Richness, Phylogenetic diversity, Rarity
