Year io Monitoring ofthe_Smith Island/Union Slough Habitat Restoration Site I Everett Public Works This scope of work also includes the following two tasks to accomplish project management, coordination of the project team and coordination with EPWD, and to allow for the addition of currently unanticipated services under this scope of work should they be requested by EPWD: 6. Project Management and Coordination 7. Unauthorized Additional Services-if/as requested Year io Monitoring Tasks 1. Vegetation Monitoring(intertidal oligohaline vegetation species diversity and native species community development) • -June 2017(depending on time of flowering)-survey site for locations of colonization by purple loosestrife and yellow-flag iris and collect GPS points of all major areas of infestation. • July or August 2017-contract with SkyPix to fly 2017 aerial photo at lowest tide conditions in mitigation site and provide aerial photo interpretation of site conditions to determine vegetation community extent in GIS,and to provide comparison with community extent in Years 1-8. o Aerial photo will also be used to interpret development of tidal channels/drainage patterns(as per Task 2). • July or August 2017-conduct 12 field transects and 120 quadrat plots completed over maximum of 4, io-hour field days(including travel)to identify intertidal oligohaline vegetation diversity(identified to species)within each plot, percent cover of each species within each quadrat plot, GPS extent of each vegetation community extent along each transect and verification of aerial photo interpretation. • Collect site photos from each previously used photo point Deliverables: • Summary email and figure illustrating locations and extents of purple loosestrife and yellow-flag iris prepared immediately after field effort,for use by EPWD in control efforts. • The aerial photo,vegetation data collected, and results of the analysis will be summarized in a section the report that is the Task 5 deliverable. Assumptions: • As per approved April 3, 2014 Revised Mitigation Plan Addendum, monitoring of trees and shrubs along the interior of the Union Slough dike will not be conducted. • Purple loosestrife/yellow-flag iris survey will be timed to coincide with flowering to facilitate identification, and will be conducted by canoe on rising tide to facility efficient movement around the site and access to all areas of infestation.
