There are serious concerns about the negative effects of climate change and land conversion on biodiversity. This study investigates the combined effects of climate warming and land-use change on plant species distribution in Sweden. The results show that species associated with warmer climates have increased, while grassland specialists have declined. Climate warming and vegetation densification through grazing abandonment have synergistic effects on species distribution change. Local extinctions are related to high levels of warming but can be reduced by grassland retention. Colonisations occur more often in areas experiencing high levels of both climate and land-use change, indicating time lags in warming-related extinctions. The study highlights the importance of reducing greenhouse gas emissions and preserving valuable habitats for the conservation of threatened species.
Serious concerns exist about potentially reinforcing negative effects of climate change and land conversion on biodiversity. Here, we investigate the tandem and interacting roles of climate warming and land-use change as predictors of shifts in the regional distributions of 1701 plant species in Sweden over 60 years. We show that species associated with warmer climates have increased, while grassland specialists have declined. Our results also support the hypothesis that climate warming and vegetation densification through grazing abandonment have synergistic effects on species distribution change. Local extinctions were related to high levels of warming but were reduced by grassland retention. In contrast, colonisations occurred more often in areas experiencing high levels of both climate and land-use change. Strong temperature increases were experienced by species across their ranges, indicating time lags in expected warming-related local extinctions. Our results highlight that the conservation of threatened species relies on both reduced green-house gas emissions and the retention and restoration of valuable habitat.
