Navarro L. 2007. Restoration of Stream Integrity: Assessment of Potential Structural Barriers to the Passage of Aquatic Organisms in Mount Desert Island Streams. National Park Service
FIELD WORK: June 1 to August 16, 2007. Table of contents includes: General presentation, issues and goals, budget; preliminary work, selection of streams and crossings to assess priority, structures identification system, protocol selection; data collection; results, assessed structures: inventory, electro-fishing, stream profiles; data analysis, fragmentation degree: 'aquatic organisms passage' quality, structures ranking by restoration priority within each stream, stream ranking by restoration priority, mapping, database; Management, short and mid-term decisions, scheme for request of funds, future prospects; discussion and conclusion; acknowledgments; references; appendices. 97 crossing over 44 rivers were evaluated, and included 58 culverts, 34 bridges, and 5 dams. Electrofishing 50 m upstream and downstream of each structure (1287 brook trout were captured), also took measurements of stream profile. /STUDY LOCATIONS:/ /MOUNT DESERT ISLAND/breakneck Brook/Canon Brook/Cromwell Brook/Duck Brook/Heath Brook/Richardson Brook/Lurvey Brook/Marshall Brook/
