New corridor tool: Makurhini

Makurhini (Connect in Purépecha language) is an R package for calculating fragmentation and landscape connectivity indices used in conservation planning. Makurhini provides a set of functions to identify connectivity of protected areas networks and the importance of landscape elements for maintaining connectivity. This package allows the evaluation of scenarios under landscape connectivity changes and presents an additional improvement, the inclusion of landscape heterogeneity as a constraining factor for connectivity.

The network connectivity indices calculated in Makurhini package have been previously published (see Resources below), and it allows the integration of efficient and useful workflow for landscape management and monitoring of global conservation targets.
