Summary

Riparian ecosystems are valuable to the ecological and human communities that depend on them. Over the past century, they have been subject to shifting management practices to maximize human use and ecosystem services, creating a complex relationship between water policy, management, and the natural ecosystem. This has necessitated research on the spatial and temporal dynamics of riparian vegetation change. The San Acacia Reach of the Middle Rio Grande has experienced multiple management and river flow fluctuations, resulting in threats to its riparian and aquatic ecosystems. This research uses remote sensing data, GIS, a review of management decisions, and an assessment of climate to both quantify how riparian vegetation has been [...]

Purpose

A land cover classification was created for each date constraining the management phases, 1935, 1962, 1987 (twice), 1999, and 2014. The 1935, 1962, and first 1987 classifications were produced by digitizing aerial imagery. The second 1987 classification, 1999, and 2014 classifications were created using a Classification and Regression Tree (CART) model. This data set contains the six different land cover classifications that were used in this research.
