Phase I: Cattail Control and Restoration Planting in Loring Pond (2012-Summer 2014)

The MN DNR Fisheries Division granted permits the MPRB to allow cattail removal from the shoreline edge out to open water in select areas of Loring Pond. The permits also included restoration of native emergent vegetation in a 100 linear foot area near the fishing dock.

Applied Ecological Services (AES) worked as a contractor for the MPRB from 2012 to the summer of 2014 on Loring Pond cattail control under the MN DNR permits. AES used several management techniques including mechanical cutting, hand pulling and specific targeted herbicide treatments using a MN DNR approved herbicide. AES also planted native emergent vegetation into the 100 foot restoration area in 2013 and maintained this planting through the 2014 growing season.

Phase II: Fall 2014 Cattail Control Project

The Minnesota State Senate passed Legislation in 2014 to authorize the MPRB to "remove all hybrid and narrow-leaved cattails by mechanical removal and chemical control at Loring Lake in Hennepin County, and replant the shoreland with native species." This authority continues into the future.

Starting in early October 2014, AES cut cattails in all areas of Loring Pond. At this time, as many cattails as possible were cut below the surface of the water in order to maximize cattail suppression through without using chemicals. Keeping as many cut stems under water as possible was an effort to weaken and suffocate the cattails and reduce cattail biomass to allow for views of the pond.

During this project, it was found that the North Bay of Loring was predominantly a floating mat of cattails. There was also a smaller mat of cattails in the South Bay. It is not possible to cut a floating mat of cattails below the surface of the water. Cattail mats float in the water and when cattails on the floating mat were cut, the mat floated higher in the water. Additionally, it was not possible to cut cattails growing in very shallow water conditions beneath the surface of the water.

MPRB expects cattail regrowth to be strongest in shallow water areas and on the floating cattail mats. In these areas, cattails began to sprout in late-April 2015. There will be significant and notable cattail growth in these locations during the 2015 growing season.

Future Vegetation Management Work at Loring Pond

As with other invasive or aggressive species, complete eradication of narrow–leaved and hybrid cattail at Loring is not possible.

The MPRB is evaluating future options for shoreline and emergent vegetation management that increase native plant diversity and decrease cattail dominance in Loring Pond.

2015-Present

The Minnesota State Senate passed Legislation in 2014 to authorize the MPRB to “remove all hybrid and narrow-leaved  cattails by mechanical removal and chemical control at Loring Lake in Hennepin County, and replant the shoreland with native species” (2014 Minnesota Session Laws, Chapter 290, Sec. 60). MPRB and its contractor have been working in accordance with this Legislation since the Legislation was passed.

2016 Pesticide Application Board Action

In 2016, the Board of Commissioners passed an action that eliminated all products with glyphosate as an active ingredient within neighborhood parks. This action excluded projects that are currently in process, which includes Loring Park Pond Cattail Control.

Phase III Loring Pond Cattail Control and Vegetation Management

On July 1, 2015, the MPRB approved a Professional Services Agreement with Applied Ecological Services, Inc. (AES), for $130,126.91 to provide hybrid and narrow-leaved cattail control, re-establish emergent vegetation, and plant an upland buffer at Loring Pond at Loring Park from July 1, 2015 to December 31, 2018.

Cattail control for the North Bay under this contract includes one season (2015) cattail control in the North Bay using mechanical and herbicide treatments. Work on the North Bay floating mate involves a late summer herbicide application followed by removal of the resulting dead cattail stems from the North Bay floating cattail mat when ice is on the lake (winter 2015-2016).

South Bay work includes cattail control using mechanical and herbicide treatments. Planting of native aquatic emergent vegetation into the South Bay will occur during the summer of 2016. Cattail control and maintenance of the emergent vegetation is included in the Phase III contract.

Establishing an upland buffer with native plant species is planned work for 2016-2018. This work includes site preparation for one growing season, seeding with native upland plants and follow up maintenance.

August 2017 Professional Services Agreement Amendment #1

Work activities for the 2015 Professional Services Agreement with Applied Ecological Services were changed through Amendment #1 to the Contract. This did not involve adding any funds to the project, but replaced the site preparation and seeding of the upland buffer planting with an additional one-time cattail control in the North Bay. Cattails from the North Bay herbicide treatment will be cut and hauled out of the park in the winter (2017-2018) by AES when ice is on the lake.

North Bay cattail control work will consist of a one-time herbicide application in late summer 2017 to control the seeding of cattails the North Bay. This work activity will control the seeding of cattails and provide staff additional time to develop strategies for future control of the floating mat. The dead cattail stems will be removed from the North Bay in the winter of 2017-2018 when ice is on the lake.

Background

Emergent plants are rooted in the bottom of the lake with leaves and stems above the water. They are important lake vegetation, providing habitat for fish and a variety of birds.

Narrow-leaved and hybrid cattails are very aggressive emergent plants that can out-compete other vegetation. These cattails thrive in shallow water and in lakes and wetlands where water levels fluctuate frequently. Narrow-leaved and hybrid cattails also have the ability to grow in drier upland settings such as ditches and even saturated soils found in along upland edges of lake shorelines. Narrow-leaved and hybrid cattails have become the dominant emergent vegetation in Loring Pond.

The MPRB is evaluating future options for shoreline and emergent vegetation management that increase native plant diversity and decrease cattail dominance in Loring Pond.
