VALIDATING RAPID ASSESSMENT FOR EPISODIC STREAMS
Many of the Arid West’s streams are characterized by episodic, ephemeral flow conditions, but they have been underrepresented in research and management. Assessment tools for these streams are necessary to prioritize streams for protection or restoration, assess impacts, and evaluate mitigation efforts. Previous work developed an initial module of the California Rapid Assessment (CRAM) for episodic streams, and this project refined and clarified the assessment method before employing it. CRAM is organized to guide the user through the stream’s structure from landscape level to site-specific plant community composition. Project partners concurrently collected samples of terrestrial invertebrates and bryophytes, with the goal of developing an index of condition, and these data will be used to validate the rapid assessment. The site selection process targeted Arizona and California’s arid regions, including the Mojave and Sonoran Deserts, The Mogollon Rim, Death Valley, Owens Valley, Mono Lake, the Central Coast, and the Modoc Plateau, and a pending phase will include the southern San Joaquin Valley. Initial results indicate that the rapid assessment is functioning as intended to measure a full range of environmental conditions.
