Man-made stream barriers such as low-head dams and culvert road crossings are detrimental to stream ecology in a multitude of ways and are of concern to natural resource managers, biologists, and ecologists. This concern extends to fish and other aquatic organism passage and movement, aquatic organism population genetics, sediment transport, stream bank erosion, water quality / limnology, etc. Because streams are linear systems, those flowing through natural areas can be significantly impacted by barriers within natural areas as well as those upstream or downstream. Therefore, natural area managers should be aware of and supportive of barrier removal projects that restore stream system connectivity, regardless of the actual location of the barrier.
This discussion will demonstrate how stream barriers can be inventoried, prioritized, and removed. Examples will include national perspectives including some western states, the Southeastern US, and specifically, Arkansas. Also, programs and projects from the Southeast Aquatic Resource Partnership (SARP) and the Arkansas Stream Heritage Partnership will be highlighted.

State Natural Areas Programs were among the first entities to protect natural areas in North America. Almost 50 years ago, these programs came together and addressed a need for a unifying voice and community where practitioners and academics could share information, techniques, methodologies, good science and even moral support. Hence the formation of NAA. Since those days, our community has grown to include other natural areas professionals that work at the federal, regional and non-profit level.
