Name Summary Description
The Circuitscape Project Circuitscape is a free, open-source program that combines circuit theory and least-cost path analysis to determine where potential corridors could be placed.
Conefor Conefor is a software package that allows quantifying the importance of habitat areas and links for the maintenance or improvement of landscape connectivity.
Connect: Connectivity Modeling Toolbox Connect is a set of tools that helps researchers and conservation planners model landscape connectivity for multiple wildlife species in complex heterogeneous landscapes.
Connecting Landscapes An explicit web-based guidance program intended for natural resources and conservation practitioners (managers, planners, biologists, ecologists) that need to model, assess, and plan for connectivity.
Connectivity Analysis Toolkit The Connectivity Analysis Toolkit combines several new connectivity analysis and linkage mapping methods in an accessible user interface and especially facilitates calculation of ‘centrality’ metrics.
Corridor Design A website that includes step-by-step procedures for modeling corridors along with ArcGIS tools that are best suited for designing corridors in a heterogenous landscape at a regional (e.g. 2 – 500 km long) scale.
FunConn FunConn is an ArcGIS toolbox that allows users to create terrestrial habitats and landscape network models based on a animal’s vegetation affinities, so a landcover layer is the minimal dataset required (no sampling data required).
GFlow GFlow is open-source software designed to expand the capacity of Circuitscape and address connectivity problems over large landscapes, across multiple taxa, and at high processing speeds. Primarily designed to be used in a High Performance Computing environment, it can be used on desktop computers for smaller problems at slightly lower performance levels.
Gnarly Landscape Utilities GIS tools that support basic steps of connectivity mapping such as creating resistance and habitat layers and core area mapping, which can be used by software like Linkage Mapper and Circuitscape.
Grainscape Package for R that can be used to calculate effective distances for landscape connectivity at multiple scales.
Graphab Software for modeling ecological networks that assists with constructing graphs, computing connectivity metrics, integrating connectivity metrics into species distribution models, and visual and cartographic interfacing.
GuidosToolbox Software collection with a variety of modules targeted to investigate several spatial aspects of raster image objects such as pattern, connectivity, fragmentation, or cost.
Linkage Mapper Linkage Mapper is a GIS tool designed to support regional wildlife habitat connectivity analyses. It consists of several Python scripts, packaged as an ArcGIS toolbox, that automate mapping of wildlife habitat corridors.
UNICOR Universal Corridor Network Simulator: species connectivity and corridor network simulator that uses different landscapes and species distributions, with results that can be used to designate sites as potential source or sink populations, identify corridors, barriers, and population connectivity of keystone patches, and characterize zones for species persistence, vulnerability, and isolation.
The Yale Framework A Climate Adaptation Framework that includes advice and tools to assist conservation planners in selecting the assessment and modeling strategies that fit their needs.
Zonation Zonation is a conservation planning framework and software that identifies areas important for retaining habitat quality and connectivity for multiple species, indirectly aiming at species’ long-term persistence.
