Invasive Species Science

Acting Branch Chief: Tom Stohlgren

FORT scientists in the Invasive Species Science Branch develop models to understand and forecast invasive species distribution and spread, and conduct research to develop methods for control and prevention of invasive reptiles and amphibians.

New Software for Assisted Habitat Modeling Package for VisTrails

A new addition to FORT's Resource for Advanced Modeling will significantly enhance habitat suitability and species distribution modeling. The Software for Assisted Habitat Modeling (SAHM), released in March 2012, was created to both expedite habitat suitability modeling and help maintain a record of the various input data, pre- and post- processing steps, and modeling options incorporated in the construction of a species distribution model. SAHM is constructed as a "package" of modules that can be used within VisTrails, an open-source management and scientific workflow system designed to integrate the best of scientific workflow and scientific visualization systems. SAHM works by combining environmental predictor layers of the study area — such as climate and remote sensing data — with field sampling measurements for a particular species. The program then runs statistical models using these data to analyze habitat requirements of the species of interest and predict its potential distribution based on habitat suitability. Model outputs help land and natural resource managers generate maps to aid in predicting and managing species of concern.
