Summary

The purpose of the classification and vegetation map is to aid management of the Pine Creek and Fitzhugh Creek Wildlife Area. A separate attribute noting invasion by Juniperus occidentalis was added at the request of regional staff.

Description

This fine-scale vegetation classification and map of the Pine Creek and Fitzhugh Creek Wildlife Areas, Modoc County, California was created following FGDC and National Vegetation Classification Standards by the California Department of Fish and Wildlife Vegetation Classification and Mapping Program VegCAMP. The map classification is based on a floristic classification that was derived from data collected in the field following the California Native Plant Society's Rapid Assessment protocol (www.cnps.org) in June, 2006 and analyzed by VegCAMP using cluster analysis to derive the classes. The map was digitized using true-color 2005 1-meter National Agricultural Imagery Program (NAIP) imagery as the base. Almost all polygons were field checked and corrected in June 2007.

Supplemental information
Rapid Assessment data were collected from 76 vegetation stands during the periods June 6-9 (Fitzhugh Creek) and June 19-23 (Pine Creek), 2006 following the California Native Plant Society's Rapid Assessment protocol (www.cnps.org). Data were entered into an Access database ("PineFitzhugh_Analysis_final.mdb" available from VegCAMP). Sample point locations are in a separate shapefile, "RA_pts." The Rapid Assessment data include the date of sampling, GPS location, environmental characteristics of the sampled stands (microtopography, substrate, soil texture, slope, aspect, ground surface characteristics, disturbance type and intensity), vegetation structure (tree, shrub and herb cover and height, total vegetation cover), species cover, site history, and the alliance and association. Additionally, four digital photos were taken in the cardinal directions from each sample location are available from VegCAMP. These Rapid Assessment data and field photos can serve as a baseline for monitoring. Species cover data were analyzed using PC-Ord software's cluster analysis. The final analysis used the Sorensen distance and flexible beta linkage method at -0.25 (McCune and Grace 2002). This cluster analysis technique was based on abundance (cover) values converted to seven different classes using the following modified Braun-Blanquet (1932) cover categories: 1=<1%, 2=1-5%, 3=>5-15%, 4=>15-25%, 5=>25-50%, 6=>50-75%, 7=>75%. The set of data collected in Pine Creek and Fitzhugh Creek WLAs was used as the principal means for defining the association composition and membership rules; however, pre-existing classifications and floras were consulted to locate analogous/similar classifications or descriptions of vegetation. Naming conventions followed the National Vegetation Classification System (Grossman et al. 1998) and the California Native Plant Society (Sawyer and Keeler-Wolf 1995). An association is defined by a group of samples that have similar dominant and characteristic species in the overstory and other important or indicator species, whereby these species are distinctive for a particular environmental setting. A set of similar associations is grouped hierarchically to the next higher level in the classification, the alliance-level. Following is a key to identify all classification vegetation types in the field. I. Stand is tree dominated. Stand has at least 3% tree cover (however, if JUOC is < 10% and Artemisia tridentata or Prunus virginiana is greater than 10% cover, then go shrub part of key). I.A. Pinus jeffreyi is the dominant tree species. IA.1. Abies concolor is at least subdominant and Juniperus occidentalis is present at low cover (Smith 1994)(FCWA0014, PCWA0017) Pinus jeffreyi - Abies concolor / Symphoricarpos rotundifolia / Poa spp. Association IA.2. Juniperus occidentalis is subdominant and Cercocarpus ledifolius occurs in the understory at over 5% cover. Pinus ponderosa may be present or up to co-dominant with Pinus jeffreyi. May be like the Pinus jeffreyi - Purshia tridentata - Cercocarpus ledifolius - Stipa occidentalis of Smith 1994, but is closer to her Pinus jeffreyi / Cercocarpus ledifolius due to constancy of Juniperus occidentalis and cover of Pinus jeffreyi Pinus jeffreyi / Cercocarpus ledifolius Association IA.3. Cornus sericea is present; Salix lucida ssp. caudata may be present. Riparian habitats Pinus jeffreyi / riparian Association I.B. Juniperus occidentalis is the dominant tree. IB.1. Pinus jeffreyi is present and generally at least 1% cover. Usually contains Purshia tridentata, and/or Prunus virginiana and may have Ribes velutinum and Symphoricarpos rotundifolius Juniperus occidentalis - Pinus jeffreyi / (Purshia tridentata) - (Prunus virginiana) Association IB.2. Artemisia arbuscula is present and Pinus jeffreyi is absent Juniperus occidentalis / Artemisia arbuscula Association II. Stand is shrub dominated. II.A. Cornus sericea is the dominant shrub. Salix lucida ssp. caudata is present Cornus sericea - Salix lucida ssp. caudata Association II.B. Salix lemmonii is the dominant shrub or co-dominates with Salix lucida ssp. caudata, and Cornus sericea is absent Salix lemmonii Association II.C. Artemisia tridentata is the dominant or co-dominant shrub. IIC.1. Artemisia arbuscula co-dominates the stand Artemisia tridentata - Artemisia arbuscula Association IIC.2. Chrysothamnus nauseosus is present and Artemisia arbuscula may be present, but is never dominant or codominant Artemisia tridentata - Chrysothamnus nauseosus Association (Ferren and Davis 1991) II.D. Artemisia arbuscula is the sole dominant shrub in the stand with at least 3% cover. IID.1. Poa secunda is generally the dominant perennial grass, and Festuca idahoensis and Pseudoroegneria spicata are generally absent. Native perennials such as Lomatium bicolor and Antennaria dimorpha may be common. Stands of this type are found on the shortest mounds Artemisia arbuscula - Poa secunda Association IID.2. Festuca idahoensis co dominates with Poa secunda and Pseudoroegneria spicata is absent. Stands of this type are found on the low to intermediate mounds Artemisia arbuscula - Festuca idahoensis Association (Stillman 1980) IID.3. Pseudoroegneria spicata and Poa secunda are present. Festuca idahoensis is generally absent. Stands of this type are typically on the tallest mounds, often with Elymus elymoides and Leymus cinereus Artemisia arbuscula - Pseudoroegneria spicata Association II.E. Prunus virginiana is the sole dominant shrub Prunus virginiana Alliance only III. Herb dominated. III.A. Stand dominated by Allium platycaule.
