142 EVALUATION OF AN HERBICIDE APPLICATION ON VEGETATED HABITAT AND THE STRUCTURE OF A FISH AND MACROINVERTEBRATE COMMUNITY IN MINNESOTA LAKES. J.G. Slade and E.D. Dibble, Department of Wildlife and Fisheries, Mississippi State Univ. ABSTRACT Macrophytes provide important habitat complexity mediating structure of aquatic communities in lakes. We investigate the hypothesis that removal of exotic, invasive macrophytes because of changes in this complexity will alter fish and macroinvertebrate populations. A four lake experiment was conducted in the Minneapolis, Minnesota metropolitan area (June 2003-September 2004) to measure herbicide effects on the structure of the aquatic community. A BACI (before–after/control–impact) sampling design was used to evaluate change in structural habitat (stem frequency) by removing two exotic plant species (Myriophyllum spicatum and Potamogeton crispus) and its effect on the abundance and richness of fish and macroinvertebrates. As an experimental treatment, a low-dose, species-specific herbicide application was made to remove the two species in two of the lakes. Pre- and post-treatment fish and macroinvertebrate population data were collected, and the treatment effect was evaluated using repeated measures two-way analysis of variance. A multi-sampling approach using popnets, boat-mounted electrofishing, and seining was deployed to ensure accuracy in fish data. Our data documented significant loss of the two exotic species however no treatment effect was noted on macrophyte stem frequency, or abundance and richness of the fish and macroinvertebrate community. No change in stem frequency was noted due to the immediate replacement by native macrophytes. Temporal (seasonal) effect in the abundance and richness of macrophyte, fish, and macroinvertebrate communities was noted. We conclude that there was no immediate effect of removing the habitat complexity on the fish and macroinvertebrate community by using an herbicide to remove two exotic macrophytes in the four Minnesota Lakes. ---------- Jeremy Slade is a recent graduate from the Department of Wildlife and Fisheries, Mississippi State University (MSU).

143 USE OF THE AQUATIC HERBICIDE RENOVATE (TRICLOPYR) IN PHRAGMITES AUSTRALIS CONTROL PROGRAMS. D. Roach, All Habitat Services, LLC, S. Hyde, SePRO Corporation, and S. Living, All Habitat Services, LLC. ABSTRACT SePRO Corporation, in cooperation with All Habitat Services, LLC, has conducted experimental trials to evaluate the effectiveness of the aquatic herbicide Renovate (triclopyr TEA) to control the invasive species Phragmites australis. Renovate is a proven systemic aquatic herbicide used for selective control of broadleaf (dicots) and woody plants. Field development work from 2003-2005 has demonstrated a significant ability to control invasive Phragmites (monocot) populations. The effectiveness of Renovate early in the growing season and the opportunity of rapid recovery of desirable grass (monocot) species provide a new and valuable tool in the management of Phragmites australis. Important benefits include; an expanded management window, release of desirable monocot species, reduced biomass, compressed restoration timelines, and perennial rhizome suppression. The presentation will include a discussion of current Phragmites control programs, pre-treatment and post-treatment observations from Renovate field evaluation projects, as well as information on the future potential of Renovate prescriptions in Phragmites management programs.
