Project Title: Boundary Line Maintenance, Cabin Lot Surveys, Ground Maintenance, Clarence Cannon NWR HREP Year 1, and 2023 Forestry Projects

This project involves conducting boundary line maintenance and cabin lot surveys as well as ground maintenance. Boundary maintenance and cabin lot surveys will take place along the Mississippi River in River Pools 24 and 25, lower Mississippi, and along the lower Illinois River). Total distance is approximately 46.6 miles of boundary line maintenance (Section 1.0) and the survey of 37 cabin lots (Section 3.0). The project will also authorize the replacement of missing and damaged monuments by a certified surveyor (Section 2.0). The cabin lot surveys will include a survey of the currently leased subdivision lots, pinning, and demarcation by placement of boundary signs at the 4 corners of the lot.

Ground maintenance will include herbicide spraying for invasive species control, mowing, and the use of a seed drill. Maintenance will take place at the Riverlands Migratory Bird Sanctuary in St. Charles County, MO and Timber Ridge Natural Area in Madison County, IL. (Sections 4.0 and 5.0)

Forestry projects include a large amount of timber stand improvement and supplement tree planting in Mississippi River pools 24 and 26 near Ashburn, MO and St. Charles, MO. (Sections 6.0 and 7.0)
