rangemap

A collection of tools to create species range maps based on occurrence data, statistics, and spatial objects. Other tools in this collection can be used to analyze the environmental characteristics of the species ranges. Plotting options to represent results in various manners are also available. Results obtained using these tools can be used to explore the distribution of species and define areas of occupancy and extent of occurrence of species. Other packages help to explore species distributions using distinct methods, but options presented in this set of tools (e.g., using trend surface analysis and concave hull polygons) are exclusive. Description of methods, approaches, and comments for some of the tools implemented here can be found in: IUCN (2001) , Peterson et al. (2011) , and Graham and Hijmans (2006) .
