Appendix C: Global and local plant community descriptions Ecological systems placement: Ecological system unique ID CES304.775 Ecological system name Inter-Mountain.Basins.Active.and.Stabilized.Dune NatureServe conservation status: Distribution: Global rank. G5? (23-Feb-1994). Globally. This association is known from the Colorado Plateau west into the Great Basin and northern Mojave Desert. Petrified Forest National Park. Krascheninnikovia lanata Dwarf-shrubland was identified from one relevé. It was located on a sand dune/sandsheet at Petrified Forest National Park northwest of Pilot Rock. Environmental summary: Globally. This association is known from the Colorado Plateau west into the Great Basin and northern Mojave Desert and in the panhandle of Texas. It is an alkaline dwarf-shrub association that occurs primarily on sandsheets, slopes, and plains often on eolian deposits near canyon walls and in alkaline flats in and around playas and along washes. Sites are gentle to steep (up to 40% slope) and occur between 800 and 1770 m (2620-5800 ft) elevation. Soils are rapidly drained loamy sands from alluvium derived from a mixture of rocks such as granodiorite, quartzite, latite, limestone, and basalt in southern Nevada (Faden 1977) and sandy loams derived from Navajo and Entrada sandstones in southeastern Utah that have eroded and been redeposited by wind and water. It occurs on low to high levels of soil salinity and alkalinity. In Texas, this community occurs on shallow soils on ridges and on footslopes along the Canadian River. In general, the soils are redbed-derived and shallow in nature. It would seem that this shrub is able to grow on a variety of soils but prefers the shallower, rocky areas. It is often found growing in association with other shrubs but may grow alone in small colonies. When this community is found, it is never extensive and rarely occupies more than a third of an acre. There is usually some evidence of deer browsing on this species, and in areas where it is accessible, domestic livestock will browse it as well. Petrified Forest National Park. This association occurred at 1770 m (5800 ft) elevation. USFWS wetland system: Palustrine. Vegetation description: Globally. On the Colorado Plateau, total vegetation cover ranges from 5 to 45% and is characterized by the dwarf-shrub Krascheninnikovia lanata with cover between 5 and 30%. In southern Nevada, scattered Ambrosia dumosa, Atriplex polycarpa, Larrea tridentata, Lycium andersonii, Sphaeralcea ambigua, and Suaeda moquinii (= Suaeda fruticosa) may be present (Faden 1977). The herbaceous layer is poorly developed but may contain tufts of the grass Achnatherum hymenoides. Forbs commonly present include Eriogonum spp., Opuntia polyacantha, Oenothera pallida, Plantago patagonica, and Sphaeralcea parvifolia. Biological soil crusts provide up to 45% cover. Introduced annuals Bromus tectorum, Bromus rubens, and Salsola tragus may be abundant on some sites. In Texas, this small community is dominated by Krascheninnikovia lanata, with some other short shrubs also being present in lesser amounts. Associated shrubs present in the community include Dalea formosa, Mimosa borealis, Atriplex canescens, and occasionally small Prosopis glandulosa. The community gives the appearance of being droughty and forbs are few. Tetraneuris scaposa, Gutierrezia sarothrae, Chaetopappa ericoides (= Leucelene ericoides), Paronychia jamesii, and Eriogonum longifolium are the most common. The most common grasses C43
Vegetation Classification and Distribution Mapping Report: Petrified Forest National Park are Aristida purpurea, Hesperostipa neomexicana (= Stipa neomexicana), Bouteloua gracilis, and Bouteloua curtipendula. Petrified Forest National Park. Only one relevé was classified as Krascheninnikovia lanata Dwarf-shrubland, with total vegetation cover of 34%. This vegetation cover consisted of 31% cover in the shrub stratum and 3% cover in the herbaceous stratum. The species diversity was 15 species. The vegetation in the shrub layer was dominated by Krascheninnikovia lanata, with 30% cover. Most abundant species: Stratum Global species PEFO species Short.shrub/ Krascheninnikovia lanata Krascheninnikovia lanata sapling Other noteworthy species: Global species Bromus tectorum PEFO species Data are not available.
