Results: Corncrakes were present in grassland and arable fields, and preferentially occupied remote areas that were wet and flat, and had high land cover diversity at the 100 ha scale. The simulation of land cover diversity loss revealed that even a moderate reduction of land cover diversity could drastically reduce the extent of suitable Corncrake habitat.

Land managers currently lack a coordinated climate change adaptation approach with which to prepare the region's globally outstanding biodiversity for accelerating change. We provided analyses intended to inform coordinated adaptation for eight focal rainforest tree species of commercial importance and broad rainforest communities. By using two different approaches to determine vulnerability, including climate envelope modeling (Maxent) and the MC1 dynamic vegetation model, we were able to assess where Pacific coastal rainforests might be more stable over time. We examined vegetation stability based on climate projections and used protected areas and intact late-seral forest data to determine priority areas and current level of protections. Based on model outputs, focal rainforest conifers and general rainforest communities are more likely to persist and to expand their ranges along northern range margins while southern margins exhibited lower persistence and potential loss of suitable climate.

Land managers currently lack a coordinated climate change adaptation approach with which to prepare the region's globally outstanding biodiversity for accelerating change. We provided analyses intended to inform coordinated adaptation for eight focal rainforest tree species of commercial importance and broad rainforest communities. By using two different approaches to determine vulnerability, including climate envelope modeling (Maxent) and the MC1 dynamic vegetation model, we were able to assess where Pacific coastal rainforests might be more stable over time. We examined vegetation stability based on climate projections and used protected areas and intact late-seral forest data to determine priority areas and current level of protections. Based on model outputs, focal rainforest conifers and general rainforest communities are more likely to persist and to expand their ranges along northern range margins while southern margins exhibited lower persistence and potential loss of suitable climate. Robust reserve design for temperate rainforests should include current and future late-seral forests as potential climate refugia to accommodate projected shifts in species of commercial and ecological importance. |

Our study shows that coexistence of humans and carnivores is possible, even without direct economic incentives. A key challenge for settings with a discontinuous history of human-carnivore coexistence is to reinstate both practices and attitudes that facilitate coexistence. |
