Planning for the Restoration of Functional Connectivity in Brazil
Aim
Land use and land cover (LULC) change is the main driver of biodiversity loss, causing habitat loss and fragmentation that hinders species movement and negatively impacts populations. While habitat fragments are structurally disconnected, functional connectivity can still occur depending on the species' dispersal abilities. Incorporating landscape connectivity into restoration planning helps identify strategic areas significantly enhancing connectivity. Here, we present an unprecedented, nationwide continuous spatial layer representing each restorable pixel's contribution to functional connectivity, using Brazil as a case study.
Location
Brazil.
Methods
We performed a dynamic pixel-based analysis across each Brazilian biome to assess the potential increases in the Integral Index of Connectivity (IIC) resulting from restoring each restorable pixel in the landscape. For that, we defined hypothetical species with medium, high and very high dispersal abilities and calculated the IIC for the different natural LULC in each biome. Then, we ran a dynamic pixel-based restoration analysis to assess the contribution of each restorable pixel to functional connectivity.
Results
Our resulting dataset represents the relative contribution of connectivity for each restorable pixel in the landscape, considering all dispersal abilities and LULC in each biome. Since we are assessing the contributions of individual pixels to overall biome landscape connectivity, most values are expectedly low. However, pixels with the highest contributions to connectivity show a stand-alone contribution biome-wide and thus were interpreted as priorities for restoration. Notably, we show nested regions as priorities for restoration, with a trend of higher priority rankings (e.g., the top 5% most important regions) being surrounded by subsequent rankings of priorities.
Main Conclusions
Our study is the first to evaluate the impact of restoration planning efforts on functional connectivity across all Brazilian biomes. We identified priority areas for restoration within each Brazilian biome, providing valuable information to guide decision-making and policy implementation. The innovative pixel-based analysis used in the study can be replicated in other regions, aiming to make restoration planning more efficient.
