In Attendance: Erik Olson, Craig Roesler, Douglas Kurtzweil,
Dennis Clagget, Erik- Welcomed everyone and reviewed agenda. Erik- Set up Power Point presentation · Grant Update · Update of Education and Outreach · Future Education and Outreach Doug- In reference to putting together an Invasive Species Conference for sometime in 2008 you could talk to Sawyer County Lakes Forum for collaboration. And/or work with WAL to set it up. Erik- It would be my intention to have a separate conference specifically for AIS held here at the college, and I would like to collaborate with SC Lakes Forum and WAL. Erik- Also (Future Education) I am collaborating with LCO
Conservation Department, UWEX, and LCO Tribal Historical Preservation Office
(Jerry Smith) to set up a paddle down the west fork of the Erik- Update of Research, Gave a summary of the lakes and rivers surveyed in 2005 & 2006 by the LCOOCC & LCOOCC Extension and the potential waterbodies to be surveyed in 2007. Craig- Radisson Flowage has AIS, which is down stream from the Chippewa Flowage which most likely means that AIS are moving down the river. Erik- Yes, and we hope do document that in our river surveys. Erik- EWM Survey Update Erik- Discussion of possible EWM decline from 2005-2006. Doug- It really did appear to have decreased on the east side. Erik- In conversation with LCO Conservation Dept. it did appear to have declined on the west side as well, though there is no scientific evidence to support this theory. Erik- Finished update of EWM and Native Plant Surveys. Erik- Purple Loosestrife Survey Update Dennis- Bog pieces break off of main chunk and float to shore while infested and thus contributing to the spread. Erik- We have seen entire bogs move to the shoreline and spread PL to shoreline. Bogs are a major concern because the PL appears to do well on the bogs. Erik- Updates on Management Activities. Erik- Some collaborative efforts with different agencies on control. Craig- Noticed lacewings in the PL beetle rearing enclosures and thinks that it could be possible that they are preying on the beetles. Which would explain why the beetles are not completely knocking out the PL. Beetles are not causing as much damage on PL and this could be due to predation. Erik- Updates on other Invasive Species work. Erik- Japanese Knotweed has been found on LCO and I believe
there is some in Craig- Yes, there is a patch there near Marketplace. Erik- Introduce and Erik- Grant was written from comments made by the steering
committee about a need. We are
surveying rivers and streams that flow into the Flowage and some waterbodies up
river to see if they are a source of AIS entry into the flowage. Surveyed East
fork from Barkers lake down and found an infestation of PL in the Flowage area
of the river. Surveyed the West fork
of the Chippewa and found EWM and PL in Erik- Asks Agencies for Updates. LCO Conservation Dept. Brett- The problem is most likely not so big (EWM) on the west side as it is on the east side because of the deep thoroughfare. The east side has many bars and shallow spots in areas where there is high traffic. This traffic in shallow spots could be helping spread EWM and making it worse. Chemical treatment should be focused on these areas. Dan- Need to target large colonizing patches. Focus on areas that are helping colonize other spots. Maybe the low water levels now will help knock back the EWM. Moss Creek Bottoms was fairly thick with EWM. Discussion Dennis- Could it be that EWM infestations with a sand substrate will be more affected by low water levels than the muck, because the muck provides a good spot for seeds? Erik- Possibly but there is most likely more to it. Doug- With variability of weather it will take many years to figure out what the variable or variables are that has caused this present decline. WI DNR Craig- Beetles released in Flowage and by Winter on HWY 70,
island on Radisson Flowage, Craig- Supposedly someone found Curly-leaf Pondweed in Craig- Also there was a report that there was zebra mussels near the Radisson Dam but this report was probably not valid. Checked and followed up but could not find anything. Craig- I think they could possibly be feeding on marsh
cinquefoil in Erik- Was there any other plant? Craig- I do not believe so. Erik- Brings up terrestrial invasives. Questions on activity of Japanese Knotweed and Spotted Knapweed. Everyone- Very limited action with these invasives. Neal- There are a couple volunteers pulling spotted knapweed on a roadside. Erik- What about biocontrol for spotted knapweed? Discussion about whether or not it is an issue. Dan- We have been attempting to get funding to map spotted knapweed throughout the reservation, but have had no success. Matt- The FS does some control in their old gravel pits by planting trees and shading the spotted knapweed. Discussion moves to potential survey locations for next summer. Erik- Possibly go back to Flowage and do 1,000 points to
document change. Possibly Cranberry
Lake, Craig- What about a Callahan Survey?
EWM is present and a survey could prove to be useful for management.
DNR did a partial survey of Osprey. Dan- Two Boys would be useful. PL and EWM have been seen
near the mouth of the channel. Craig- You could do less points on the Flowage, maybe 10% of your original points. That would still allow you to show year to year variability and save you time. Erik- Good idea. What
about Doug- I think that is correct. Craig- Consultant from Erik- Thanks everyone and apologizes for going over the time set. |
