Summary

A new vegetation mapping system accurately identifies native trees and marsh plants for change detection. However, distinguishing between saltcedar, mesquite, and arrowweed shrubs requires further development.

Area of Science:

  • Ecology
  • Remote Sensing
  • Geographic Information Systems (GIS)

Background:

  • Traditional vegetation mapping in the Lower Colorado River region relies on qualitative methods.
  • Accurate, quantitative vegetation data is crucial for effective wildlife refuge management and change detection.

Purpose of the Study:

  • To test a novel, low-cost aerial photomosaic system for vegetation mapping and change detection at Havasu National Wildlife Refuge.
  • To assess the system's accuracy in distinguishing various native and invasive plant species.

Main Methods:

  • Construction of a low-cost aerial photomosaic using an automated digital camera system.
  • Supplementation with oblique photographs for species composition and plant height determination.
  • Integration with Landsat Enhanced Thematic Mapper (ETM+) imagery and GIS for layered vegetation mapping (base, shrub, marsh) and Normalized Difference Vegetation Index (NDVI) analysis.

Main Results:

  • High accuracy was achieved in distinguishing native cottonwood and willow trees, as well as marsh vegetation (cattails).
  • Shrubby terrestrial vegetation, including saltcedar, arrowweed, and mesquite, could not be accurately differentiated and were mapped as a single shrub layer.
  • The system provided quantitative data, a significant improvement over existing qualitative mapping systems.

Conclusions:

  • The developed vegetation mapping system offers a quantitative approach for change detection, improving upon current qualitative methods.
  • Further research is needed to develop improved methods for distinguishing between different shrub species for more refined mapping.
