Hampshire and the South Downs

In this case study partners used the SPECIES model to project changes in potential climate space (the geographical area where climate conditions are suitable) for a range of species chosen to represent lowland heath and chalk grassland habitats. Maps were produced to show where there could be climate space for these species, both nationally and in Hampshire, under climate change scenarios for the 2020s, 2050s and 2080s (see full Hampshire report).

The potential climate space for each species was compared with their current habitat distribution and with places where opportunities for habitat creation and restoration had been previously mapped. Partners then discussed the implications with local planners and ecologists.

The study found that the lowland heath and chalk grassland of Hampshire could change significantly or even disappear in composition because of climate change. Species found in these habitats will react differently to climate change over time. The best long-term solution may be to use a range of management techniques to create new variety within designated sites, so facilitating species movement.
