Vegetation Monitoring and Assessment of the Cat Island Chain

Purpose

The objective of our project is to assess the ecological status of the created habitat behind the wave barrier and to examine how well this project is meeting the Cat Island Chain Project’s expectations. To evaluate these advancements, aquatic vegetation and water samples will be collected at the site throughout the summer for analysis. The study area will be reached by boat and will compare the exposed bay side of the island chain with the protected area behind the islands, where the restoration is hoped to occur.

Objective

The objective of this monitoring project is to assess the ecological status of the habitat behind the wave barrier created by the Cat Island Chain Restoraion Project and to examine how well this project is meeting its expectations.

Outcome

Quarterly reports and a final report for the project will be prepared for the Wisconsin DNR, and information from the project will be included in a thesis submitted as partial fulfillment for a Master’s degree from the Environmental Science and Policy Graduate Program at the University of Wisconsin-Green Bay.

Study Design

Water sampling will be conducted weekly from June 2013 through August 2013 along randomly established transects and locations that are perpendicular to the islands and extend leeward and windward of the islands. Measured water quality parameters will include chlorophyll a (as an indicator of algal biomass), total suspended solids, and ashed solids. Water temperature, water depth, and pH will also be measured. Water clarity will be assessed using a light extinction meter where water depths allow. An estimate of wave velocities will be obtained using a portable flow meter. Aquatic vegetation will also be sampled at established one-square meter plots that coincide with previous sampling done by WDNR. Vegetation surveys will be done on a monthly basis by either visual inspection and/or using a long handled, double-headed sampling rake (Kenow et. al., 2007), depending upon water levels. At each sampling location, substrate type, species composition, stem density, an estimate of total percent foliage cover and percent foliage cover for each species observed will be recorded. Seed bank samples will be harvested at randomly established locations along both the northern and southern shores of the wave barrier. Samples will be transported back to University of Wisconsin-Green Bay to assess potential vegetation under greenhouse conditions. Seed bank transplants will also be used by harvesting seed bank samples from a nearby lacustrine system. Half of these samples will be introduced at randomized locations at the study site and the other half will be taken to the greenhouse facility to further examine the occurring biotic and/or abiotic stressors at the Cat Island Chain.
