Influence of land use and flow regime on habitat and fish assemblage structure at multiple spatial scales

August 2017 - May 2020


Participating Agencies

  • Arkansas Game and Fish Commission

Flow regime and land use can be overarching factors influencing stream ecosystems. Flow regime can act as the master hydrologic variable in streams and land use and cover can influence geomorphology and hydrology. Surprisingly, the influence of these two factors on stream assemblage structure are rarely examined together. We examined the influence of flow regime and land use/cover on stream fish and crayfish assemblage structure and body condition of select species. Results of this study will be used to improve management of stream ecosystems focused on strategies related to landscape and local-scale habitat management.
