GradientLand

In Landscape Ecology, there is a lack of free softwares that can simulate sequential processes of habitat loss using neutral landscape models. Such a tool would come to the benefit of our understanding of the effects of landscape changes on ecological processes without the need of finding or manipulating appropriate natural landscapes, something both unfeasible and sometimes unethical. This paper presents a free software, named GradientLand, as a tool for generating simulated sets of habitat loss gradients as random and fractal neutral landscapes. GradientLand is of easy handling, with an intuitive interface to create a wide array of habitat cover gradient arrangements. With this tool we target students, teachers and researchers interested in landscape ecology and issues related to habitat loss and landscape change.
