WRISCs AIS goals are to offer support to organizations, agencies, businesses, landowners, and managers, volunteers, and staff, and to promote prevention, identification, monitoring, and management of AIS populations. When conducting our River and stream surveys, WRISC follows the protocol of AIS Bridge Snapshot and Project Red. When conducting lake surveys we follow the protocols of several different projects, some examples being: Exotic Plant Watch, Transect Surveys, Score the Shore, ad Point Intercept. Please read on to learn about these projects.
AIS Bridge Snapshot
When conducting what is called Wet Protocol, we follow 9 steps:
1. We approach the downstream side of the bridge or culvert.
2. We will wade through the water to investigate a total of four sites that are approximately 20 paces apart.
3. We will stand in the river just below the bridge and check the banks and surrounding wetlands for anything concerning. We will do this for a minimum of two minutes, using binoculars if needed.
4. For an additional two minutes we will spend time dragging a long handled rake, collecting submerged vegetation and woody debris, inspecting the samples for anything concerning.
5. Taking a homemade scoop or our hands we then take three samples across the channel.
6. Taking 20 paces downstream, we repeat steps 3-5.
7. After completing our four sites, we wade back upstream to the start point, being observant as we walk.
8. We collect all of our suspicious samples and follow the collection protocol.
9. Upon returning to the vehicle we scrub our boots and equipment to remove all plant material and debris.

When we follow Project RED protocol on our surveys, we follow 4 basic steps:
1. Paddle or swim to the location, keeping vigilant of suspicious specimens.
2. Collect a sample of the specimen, or photograph your findings.
3. Verify the specimen
4. Share your findings.

Exotic Plant Watch
When doing an Exotic Plant Watch samples should be collected on the first available day in Mid-June to early July.
If the lake is fairly large, several teams are recommended or several days for monitoring should be expected. After preparing the boat, the teams should follow these steps:
1. Monitor from shore out to about 15 ft.
2. Space monitoring spots evenly around the lake.
3. Make sure to sample near lake introductions (river inlets, boat launches, marinas, etc.)
4. To take sample, toss rake into water and pull specimens up. Make sure to be observant to the water as you are pulling up the rake.
5. When finding an exotic plant, make sure to take a GPS point
Transcet Surveys are very involved and extensive surveys. To learn more about this type of surveying, please click the following links.
Score the Shore
About 10 years ago there was very little about aquatic plant sampling and surveying. It was then that the Wisconsin DNR came up with Point Intercept surveying. The protocol is implemented by taking samples at points that are laid out on a geo-referenced grid. To learn more about this type of surveying and sampling click link below.
