Relationships between forest-floor invertebrate distribution, movement, and microclimate under alternative riparian management practices

Creator:: Rykken, Jessica J.
Abstract:: Headwater streams and their riparian zones are a common, yet poorly understood, component of Pacific Northwest landscapes. I sought to describe the ecological significance of headwater stream riparian zones as habitat for forest-floor invertebrate communities, and to assess how alternative management strategies for riparian zones may impact these communities. I...
