Summary

The purpose of this vegetation map and classification is to assist in management and long-term vegetation monitoring of the Fish Slough Ecological Reserve and ACEC. This effort will help document spatial and temporal changes in vegetation composition, including response to management actions. The map was requested by the Fish Slough ACEC Joint Management Committee. The mapping area (Figure 1) is Zone 1 of the ACEC; the Fish Slough Ecological Reserve is completely included within this zone.

Description

A fine-scale vegetation classification and map of a portion of the Fish Slough Area of Critical Environmental Concern (ACEC) (including the California Department of Fish and Wildlife (CDFW) Fish Slough Ecological Reserve) in Inyo and Mono Counties, California, was created by the CDFW Vegetation Classification and Mapping Program (VegCAMP). The vegetation classification is derived from floristic field survey data collected during September 2011, November 2012 and June 2013 and is based on previously described Alliances and Associations, with a few new provisional types included. The map was produced using heads-up digitizing using true-color 2012 1-meter National Agricultural Imagery Program (NAIP) imagery as the base. Supplemental imagery included 2012 1-meter NAIP Color Infrared and imagery available through Bing Maps and Google Earth. The minimum mapping unit (MMU) is 1 acre for upland habitats and -acre for wetland habitats. Field reconnaissance and field verification enhanced map quality. The final map includes a total of 365 polygons representing 40 vegetation map classes.

Supplemental information
The minimum mapping unit (MMU) is different for wetland versus upland vegetation. For wetland vegetation MMU are as follows: - -acre for delineating between vegetation types - -acre for delineating between cover class breaks in the overstory vegetation cover within a single type - -acre for delineating between cover class breaks in the understory vegetation cover within a single type For upland vegetation MMUs are as follows: - 1 acre for delineating between vegetation types - 3 acres for delineating between cover class breaks in the overstory vegetation cover within a single type Delineations were not made in upland polygons based on breaks in herbaceous vegetation cover due to seasonality and high variability of herbaceous growth between years.

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Quantitative attribute accuracy
Measure description
This map deviates from Federal Geographic Data Committee National Vegetation Classification Standards (FGDC 2008) in only one respect: there was no formal accuracy analysis performed. However, after completing map delineation and interpretation, 63% of all polygons were validated by field verification survey data. When RA, Relev, and reconnaissance data are included, 80% of all map polygons were directly visited by field personnel, and 90% had field-based descriptions or photographs. This exceeds the requirement for the national standards. Due to the inability to distinguish aerial signatures for some sparse desert shrub types and some herbaceous types, much of the map was created based solely on field data and field photographs. All field data aided in the validation and final revision of the map.
