Historical changes in biodiversity are based on land-use changes only, as there are no historical data on all the other different pressures (N-deposition, infrastructure etc). For the future development (baseline scenario), the remaining biodiversity in human-dominated land-use types ( arable land and extensively used grassland) in a specific area is added to the biodiversity value in the naturally occurring biome for that area. 100 80- 60- 40 20- Historical development of biodiversity - North America Mean species abundance (%) I eh Potential 1700 1800 1900 2000 2050 Biomes I I Trap, grassland and savannah I I Temp, grassland and steppe â Tropical rain forest â Tropical dry forest I I Mediterranean forest, woodland and shrub I I Temperate broadleaved and mixed forest [] Temperate coniferous forest â Boreal forest I I Desert I I Tundra â¡ Polar I I No biome distinction Historical development of biodiversity â Latin America and Caribbean Mean species abundance (%).
