LEFT presents a simple yet effective method for mapping ecological important landscapes beyond protected areas. The method uses existing globally available web-based databases and models to provide an ecological score based on five key ecological features (biodiversity, fragmentation, threat, connectivity, and resilience) for every 300m pixel within any given region in the world. Co-ordinates (latitude and longitude) of the site location are all that are required as input and the resulting output is a coloured map indicating ecological value across the landscape.
