Summary

To map the riparian vegetation in Mill Creek watershed.

Description

Features represent vegetation mapping for the Mill Creek Riparian Corridor, as specified for the Project Area designated in the contract between Stillwater Sciences and USFWS (USFWS Agreement No. 81330AJ365). Original mapping was performed by AIS, using 2010 NAIP imagery (1-m resolution). Stillwater performed an accuracy assessment in the field, and updated the vegetation mapping based on the observed conditions (Summer, 2013). Updates to the original file were made based on two sets of field data: 1) AA plot: the more complete field data collected at AA field plots using a modified version of the CNPS Rapid Assessment Protocol and randomly selected from stratified population of polygons in each reach, and based on land owner access agreements; and 2) map annotation: made on field maps in the field based on observed dominant species within the polygon.

The data is mapped in the National Vegetation Classification System (NVCS) to the Alliance level, as depicted in the second edition of the Manual of California Vegetation, whenever possible. A separate classification system (USDA - Meadow Hydrogeomorphic Types for the Sierra Nevada and Southern Cascade Ranges) was incorporated into the effort for classifying higher elevation meadows above 4500 ft in the upper reaches of the Mill Creek watershed.

The data steward for this map is Trisha Parker, USFWS.
