Name:
Western Interior Riparian Forest & Woodland Group
Reference:
NatureServe Biotics 2019
Description:
This group consists of riparian woody vegetation. Dominant trees may include <i>Acer negundo, Celtis laevigata var. reticulata, Cephalanthus occidentalis, Fraxinus velutina, Juglans major, Platanus wrightii, Populus deltoides ssp. wislizeni, Populus deltoides ssp. monilifera, Populus fremontii, Platanus racemosa, Quercus lobata, Salix amygdaloides, Salix gooddingii, Salix laevigata, Sapindus saponaria</i>, and <i>Washingtonia filifera</i>. Dominant shrubs include <i>Alnus oblongifolia, Baccharis salicifolia, Prunus</i> spp., <i>Salix exigua, Salix lasiolepis, Shepherdia argentea</i>, and <i>Vitis californica</i>. Other dominants on serpentine substrates include <i>Aquilegia eximia, Carex serratodens, Cirsium fontinale, Hesperocyparis sargentii, Frangula californica ssp. tomentella, Mimulus glaucescens, Mimulus guttatus, Packera clevelandii, Salix breweri, Solidago</i> spp., <i>Stachys albens</i>, and <i>Umbellularia californica</i>. The variety of plant associations within this group reflects elevation, stream gradient, floodplain width, and flooding events. It also includes springs, seeps, and perennial and intermittent streams and riparian areas found on serpentine substrates. These are disturbance-driven systems that require flooding, scour and deposition for germination and maintenance. Periodic flooding and associated sediment scour are necessary to maintain growth and reproduction of vegetation. Flooding regimes have been significantly altered in all but a few tributaries that support this group. This group occurs throughout lowlands of the interior west, including southwest warm and cool deserts and Mediterranean California, generally below about 1800 m (6000 feet) elevation. Known occurrences include the following rivers and their tributaries: Colorado, Gila, Pecos, Rio Grande, Sacramento, San Joaquin, Santa Cruz, Salt, San Pedro, Truckee, Snake and others.
