Why Model Species





Human interaction is changing landscape
Data is not Available in Quantity
Data is Biased in Many Ways
Inferential Analysis is Required
Modeling Algorithms Can Be Used
Case Study: Invasion of Weeds

Weeds are among the main threats to
biodiversity conservation

understand how wildlife areas are
vulnerable to invasion of weeds is
important to long-term conservation of
biodiversity, helping in conservation
policies.
An example: Crotalaria

Input Data for GARP


point localities where the species is known to
occur
geographic layers representing the
environmental parameters that might limit the
species' capabilities to survive
Methodology

Generate Models Predicting Occurrence in Native
Range
Methodology

Project Models Onto Invasion Area
Evaluate Vulnerability

Overlay Projections over Conserv. Units
