ST-Connect SyncroSim Package

GitHub release

Connectivity planning for future climate and land-use change

ST-Connect is an open-source SyncroSim Base Package for forecasting landscape connectivity.

ST-Connect uses a pipeline approach to chain together spatially-explicit models of landscape change and habitat connectivity. A simple ST-Connect model consists of two components. ST-Sim forecasts landscape dynamics, projecting changes in both vegetation and land use. Circuitscape predicts connectivity in heterogenous landscapes, using algorithms from electronic circuit theory.

ST-Connect’s accessible framework has helped support natural resource management projects such as a conservation prioritization project focusing on key wildlife species in Quebec (Rayfield, Larocque, Martins et al., 2021). ST-Connect is a package that plugs into the SyncroSim modeling framework. It can also be run from the R programming language using the rsyncrosim R package and from the Python programming language using the pysyncrosim Python package.


This package requires the following software:
The latest version of Syncrosim.
R version 4.0.4 or higher.
Circuitscape 5.
Zonation version 4.0.0 (optional).
