California Gap Analysis Data Dictionary Vegetation Layer A. GENERAL INFORMATION Project Name: Gap Analysis Layer Name: VEG Layer Description: This layer contains vegetation attributes for landscape scale map units, including canopy dominant species, canopy density, presence of regional endemic species, inclusion of wetland habitats, type of disturbance, and general narrative comments. Although polygons are classified into several schema, the species presence data are provided to allow customized classifications to meet a user's needs. Layer Subject: dominant plant species distribution, canopy cover, vegetation classification to Holland Natural Communities/WHR habitat types, and vegetation series, riparian and wetland types, disturbance, special interest species distribution Geographic Extent: Currently Southwestern California and Sonoran ecoregions as defined for revised Jepson Flora (except for offshore islands) Purpose of Layer: This layer was developed for the California gap analysis project to determine the distribution and current management status of the state's vegetation and habitats. By recoding the vegetation polygons into wildlife habitats, the map can also be used for similar purposes with respect to wildlife species. Following the identification of underprotected elements of biodiversity, vegetation data can help identify priority areas where a change in ownership or management could increase the amount of protection.

DATA HISTORY Source Data: Polygon boundaries were derived from photointerpretation of 1990 Landsat Thematic Mapper digital images, supplemented by 1990 HAP photography and large scale vegetation maps. Attribute data came from the 1990 HAP photography, the 1930's VTM Survey Maps (i.e., Wieslander), field visits, and large scale vegetation maps. Automation Scale: 1:100,000 Development Methods: Overview: Landscape size map units were delineated on-screen over the TM imagery on the basis of relatively homogeneous color, tone, and texture. In many cases, boundaries were added or moved based on higher resolution data from aerial photography or larger scale vegetation maps. Dominant species data were obtained from existing sources, primarily the VTM survey maps. Percent cover of the primary versus secondary types were estimated from aerial photography. Crown cover was similarly estimated. Wetlands were recorded from aerial photography. Special species were noted from existing map sources or from field observation. Disturbance was based on evidence in aerial photography. Assignment of polygons to classes such as Holland communities, Wildlife-Habitat Relationships habitat types, and vegetation series, was made by interpretation of the species list associated with each map unit.

Description of Natural Community Types Added for the California Gap Analysis Project 35110 Salvia dorri/Chamaebatiaria scrub (Dennis Odion) Description. Defined by Erhard, D.H. 1979. Plant Communities and Habitat Types in the Lava Beds National Monument, California. Masters Thesis, Oregeon State University. Moderate density of aromatic woody shrubs, mostly 1-2 m in hieght. Salvia dorrii and Chamaebatiaria millefolium are dominant, but many other Great Basin species may be present in shrub layer. Artemisia tridentata and Purshia tridentata are most important. Understory layer of scattered, diverse bunchgrasses and cheatgrass. Site factors. Well drained substratum of basalt lava flow. Elevation of big sagebrush and juniper woodland. In ungrazed areas, a possible factor in promoting the abundance of the two dominant shrubs over sagebrush. Characteristic species: Achnatherum lettermanii (Stipa), Achnatherum occidentalis (Stipa), Achnatherum speciosum (Stipa), Achnatherum thurberiana (Stipa), Artemisia tridentata, Bromus tectorum, Chamaebatiaria millefolium, Chrysothamnus viscidiflorus, Festuca idahoensis, Hesperostipa comata (Stipa), Poa secunda, Psuedoroegneria spicata (Agropyron spicatum), Purshia tridentata, Salvia dorrii. Distribution: Occurs in Lava Beds National Monument, an area of relatively recent basalt lava flows. Elevations from about 1400-1600 m. Distribution elsewhere uncertain. 35120 Rabbitbrush (Chrysothamnus nauseosus) scrub (Dennis Odion) Description: Dominated by Chrysothamnus nauseosus. Chrysothamnus viscidiflorus and Artemisia arbuscula usually present on Modoc Plateau, where shrub layer is often only .5 m tall, and rather sparse. Intervening areas dominated by Taeniantherum caput-medusae and Bromus tectorum. Confined to roadsides and other mechanically disturbed areas east of the Sierra, and mainly associated only with Artemisia tridentata under these circumstances. Site factors: Heavily grazed bottomland areas on the Modoc Plateau where soils are briefly saturated. Margins of so-called scablands, etc. Mostly roadsides east of Sierra. Characteristic species. Artemisia arbuscula, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Taeniantherum caput-medusae. Distribution: 1300-2000 m on Modoc Plateau in Bottomland areas. 1500-2000 (2500) m east of Sierra in ribbons along roads and in association with soil disturbance. 35211 Low sagebrush scrub (Dennis Odion) Description: Analogous to Subalpine Sagebrush scrub (35220), but at lower elevations. Scattered Artemisia arbuscula less than .5 m in hieght, with abundant bunchgrass. Shrub height and density decrease in low lying areas that are water logged longer during spring (scabland). Some taller Artemisia tridentata and Purshia tridentata may be mixed in. Site factors: Areas of heavy clay soil that become saturated. Elsewhere where soil generally is of finer texture and more poorly drained than where Big Sagebrush occurs. Where low sage and big sage are intermixed on the Modoc Plateau, low sage generally occupies the poorer micro- sites. Low sage may, however, dominate rocky well drained sites that appear suited for big sage on the Modoc Plateau. Low sage may dominate south facing exposures in areas where north facing exposures are dominated by big sage. Characteristic species: Achnatherum lettermanii (Stipa), Achnatherum occidentalis (Stipa), Achnatherum speciosum (Stipa), Achnatherum thurberiana (Stipa), Artemisia arbuscula, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Chrysothamnus viscidiflorus, Festuca idahoensis, Koeleria cristata, Psuedoroegneria spicata (Agropyron spicatum),Taeniantherum caput-medusae. Distribution: Dominant vegetation over lower elevations (1300-1700 m) of the Modoc Plateau. Scattered at higher elevations. 35212 Silver sagebrush scrub (Dennis Odion) Description: Similar to big sagebrush scrub, but dominated by Artemisia cana, and the relatively large bunchgrass Elymus cinereus. Other salt tolerant species (e.g. Sarcobatus vermiculatus) may be present, and increase in abundance toward bottom of basins which this type occurs in. Site factors: More finely drained soils with higher salt content than where big sagebrush occurs. Pluvial lakebeds on the Modoc Plateau. Soil surface horizons are saturated by spring accumula- tions of snowmelt runoff, which forms a perched water table over slowly permeable lower horizons. Elevations slightly above Desert Greasewood Scrub. Characteristic species: Artemisia Cana, Artemisa tridentata, Leymus cinereus (Elymus), Prunus andersonii, Sarcobatus vermiculatus, Sitanion histrix. Distribution: Modoc Plateau, north, south and east of Honey Lake. Surprise Valley. Silver Sagebrush dominates, with different associated species, in most of bottomland area of Monanche and Templeton meadows, the largest "meadows" (potential meadow systems) in the Sierra Nevada. 35310 Low Sagebrush Steppe (Dennis Odion) Description: Analogous to Sagebrush Steppe (35300), but shrubs mainly Artemisia arbuscula. Site factors: Better drained soils than where Low Sagebrush Scrub occurs. Areas less affected by grazing. Characteristic species: Achnatherum lettermanii (Stipa), Achnatherum occidentalis (Stipa), Achnatherum speciosum (Stipa), Achnatherum thurberiana (Stipa), Artemisia arbuscula, Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Festuca idahoensis, Psuedoroegneria spicata (Agropyron spicatum),Taeniantherum caput-medusae. Distribution: Scattered in Modoc Plateau region, generally at slightly higher elevations in basins than Low Sagebrush Scrub. 35500 Mountain Mohogany Cercocarpus ledifolius Woodland (Dennis Odion) Description: Scattered to nearly continuous, relatively large (2-4.5 m) Cercocarpus ledifolius with sagebrush and associated species occupying a lower stratum. Juniperus occidentalis and montane conifers occasionally present. Site factors: Well drained rocky soils. Relatively moister sites within the sagebrush zones, but relatively drier and more exposed sites within the Ponderosa Pine and White Fir zones. Characteristic species: Achnatherum lettermanii (Stipa), Achnatherum occidentalis (Stipa), Achnatherum speciosum (Stipa), Achnatherum thurberiana (Stipa), Artemisia arbuscula, Artemisia tridentata, Bromus tectorum, Cercocarpus ledifolius, Chrysothamnus nauseosus, Festuca idahoensis, Juniperus occidentalis, Pinus ponderosa, Prunus Psuedoroegneria spicata (Agropyron spicatum), Purshia tridentata, Taeniantherum caput-medusae. Distribution: Eastern Sierra on exposed ridges from 2000-3000+ m in association with Pinyon Juniper woodland, Juniperus occidentalis, etc. Great Basin, scattered in Big Sagebrush zone, becoming most abundant in Juniper woodland zone, and at ecotone between with other conifer vegetation. 35600 Wyethia mollis (Dennis Odion) Description: Predominantly perennial herbaceous vegetation strongly dominated by Wyethia, with other herbs and scattered rabbitbrush and sagebrush present. Site factors: Relatively dry logged areas. Appears to be a persistant anthropogenic type once established. Characteristic species: Artemisia tridentata, Bromus tectorum, Chrysothamnus viscidiflorus, Sitanion histrix, Wyethia mollis. Distribution: Logged areas within relatively dry portions of lower and middle montane zones (1500-2500 m). Eastern Cascades, mountains of the Great Basin, Eastern Sierra, drier portions of western Sierra, particularly north. 37210 Chamise-Buck brush chaparral (Josh Graae) 37850 Ceanothus oliganthus chaparral (Josh Graae) 42201 Pampas grass (Josh Graae) 43100 Clear cut regeneration vegetation (Dennis Odion) Description. Open shrub and herb dominated community. Tough leaved tree associates present before logging (e.g. manzanita and Ceanothus) largely replaced by soft leaved rabbitbrush and sagebrush, as well as the herb Wyethia mollis. Site factors. Fairly recent clear cut areas with associated heavy soil disturbance. Natural soil profile of litter, duff and organic horizon destroyed. Most regenerating plants fairly weedy and more typically associated with drier environments such as Great Basin sagebrush habitat. Characteristic species. Artemisia tridentata, Bromus tectorum, Chrysothamnus nauseosus, Chrysothamnus viscidiflorus, Purshia tridentata, Sitanion histrix, Wyethia mollis, Great Basin perennial grasses. Distribution. Montane areas throughout the Modoc ecoregion. Extensive on western border with Cascade ecorgion and along California/Oregon Border west of Goose Lake south towards Big Sage Reservior, and vicinity of Adin. 45010 Great Basin wet meadow (Dennis Odion) Description. Analogous to Holland's Montane Meadow. Dense growth of sedges, grasses and rushes. Generally somewhat taller (to 1.5m tall) than typical montane meadow vegetation. Very active and rapidly growing vegetation in summer due to rich soils and plentiful moisture in basins where appropriate habitat is found. Site Factors. Fine-textured, permanently moist soils. Often heavily utilized by cattle. Many areas harvested as hay and manipulated to increase coverage by grasses as opposed to sedges and rushes. Hydrology often modified by network of irrigation ditches. Characteristic species. Carex nebrascensis, Carex spp., Deschampsia caespitosa, Juncus spp., Phalaris arundinacea, many species listed under Montane Meadow in Holland. Distribution. Scattered in basins throughout Modoc Plateau region. Extensive at Steele swamp, Jess Valley, Ash Meadows, Fall River Mills, and along Pit River. 45230 Great Basin montane meadow (Dennis Odion) Analogous to Hollands montane meadow, but occurring in the more arid ranges of the Great Basin. Probably do not need to retain as a type. 71500 Cismontane Juniper Woodland 71600 Oak-Pinyon Woodland 72500 Cuyaman Pinon-Juniper Woodland 84260 Modoc white fir forest (Dennis Odion) Description. Forest strongly dominated by Abies concolor. Many of associated forest trees found with white fir elsewhere in California are not present. Understory sparse. Size of forest trees smaller (25-40 m tall) in Modoc Plateau region compared to Sierra. Understory sparse except in openings. Described by Riegel, Thornburgh, and Sawyer (1990). Site factors. Colder and more arid, continental climate than where white fir forest occurs elsewhere in the state. Preciptitation averages 454 mm at Jess Valley on the west side of the Warner Mountains (Pease 1965). Heavily impacted by cattle, particularly around the turn of the century (Pease 1965). Characteristic species. Abies concolor, Arenaria jamesiana, Artemisia tridentata (openings), Hieracium albiflorum, Lupinus caudatus, Pinus ponderosa (lower elevs.), Pinus jeffreyi (higher elevs.), Pinus washoensis (higher elevs.), Osmorhiza chilensis, Pyrola picta, Ribes viscosis- simum, Symphoricarpos vaccinoides. Distribution. 1500-2500 m elevation in all mountain ranges of Modoc Plateau. Occurs on all aspects, except at lowest elevations, where mainly restricted to north-facing slopes and mesic canyon bottoms. White fir spans the elevation gradient occupied by both white (montane) and red (subalpine) fir in the Sierra Nevada. Especially important in the Warner Mountains. 85120 Red Fir-Western White Pine Forest (or Lodgepole Pine-Western White Pine) 87100 Lower Cismontane Mixed Conifer-Oak Forest 87200 Upper Cismontane Mixed Conifer-Oak Forest 11300 Eucalyptus 11401 Mid-elevation Conifer Plantation (Dennis Odion) Description. Even-aged stands of Ponderosa Pine of varying height, but often 5-12 m tall. Canopy is usually open enough to allow sufficient light penetration to support fairly dense to dense shrub growth as described in 43100. Site factors. Sites disturbed from previous timber harvest. Soil disturbance from log skidding and transport. Fire, herbicide and tree planting among anthropogenic treatments undertaken to achieve target vegetation and attempt to maximize tree growth. Biodiversity reduced as a result (e.g. Halpern, 1995 Ecological Applications). Characteristic species. Artemisia tridenata, Bromus tectorum, Chrysothamnus nauseosus, Pinus ponderosa, Prunus emarginata, Purshia tridentata, Sitanion histrix, Great Basin perennial grasses. [Description written for Modoc Plateau; species may vary in other regions]. Distribution. Throughout Modoc Plateau region on Forest Service land at elevations ranging mostly from 1500-2500 m. Also in Sierra Nevada, Cascades Ranges, and Northwestern California. 11402 Upper-elevation Conifer Plantation
