Final Methods
This years shoreline restoration of Utah Lake included tree and brush removal using a skid steer mounted forestry disk as well as a chopper mower for removing tamarisk stands. Broadcast seeding from the Marsh Master was conducted. Phase I herbicide treatment took place in large part using aerial helicopter application of aquatic label glyphosate mixed with non-ionic surfactant. Additional broadcast treatments were conducted using the boomless sprayers mounted on the Marsh Master Machines in areas not feasible for aerial treatments. Phase II treatment of Phragmites was conducted using bother roller choppers and cutter mowers.

Project Narrative
64.5 acres of invasive trees and tamarisk were removed this year. In areas where Phragmites regrowth was limited, seeding was broadcast onto 136.18 acres. The entire shoreline was evaluated for Phragmites regrowth and 3,828.48 acres needed and received an herbicide treatment. As the lake filled some of the stands of dead Phragmites laid down thanks to the higher lake levels and ice action. Still, the Marsh Masters made a pass around the lake with roller choppers and cutter mowers and completed phase II smashing/mowing treatment on 1,241.33 acres of the shoreline.

Future Management
The plan is to continue Phase I and Phase II treatments where invasive vegetation is found on an annual basis. As we see areas free of invasive vegetation emerging the hope is that existing native seeds in the seedbank can begin to backfill these areas. When natives do not naturally return, a mix of upland/wetland seeds are broadcast to increase the likelihood of successful restoration. The ULA Conservation Biologist is leading an effort to acquire and plant a desirable diversity of wetland and emergent sedges, forbes and reeds. The ULA is working with DNR's Native Plant specialist and received the maximum grant of 10-pollinator packs which will be installed in and around the Provo River Delta this fall. 200-300 native and desirable trees are being ordered now and will be planted during the FY2024 sping/summer.
