Abstract
Human activity increases as population increases. The environment must
be altered in response to the pressures increasing population creates.
Altering the environment may pose a risk to the health of natural
habitats. The health and quality of habitats promotes biodiversity in
ecosystems. Biodiversity is necessary for a functioning ecosystem as
species work synergistically to create a livable environment. It is
therefore important to know how practices and events threaten these
habitats and the species living in them. This work details how research
is used to formulate a framework for identifying habitat threats in any
given region, determine habitat suitability, assess habitat sensitivity
to different threats, and ultimately model how the quality of habitats
change under different land use/cover scenarios. A meta-analysis of how
different authors define and characterize threat in various contexts was
done. The results of this analysis aids in the process of threat
mapping, regional analysis, and land development planning. Knowledge
gained from this study was used to evaluate regions on a watershed level
using a combination of GIS technology and the Integrated Valuation of
Ecosystem Services and Tradeoffs (InVEST) model with the goal of
performing vulnerability analyses.
