please say again where this webinar recording will be posted - thank you

Hi, we will be posting the webinars to the SSW YouTube channel, the SSW website and the fingerlakesinvasives.org website

you can always email me to get the link directly- mosher@hws.edu

Feel free to post a hello and where you are watching this from. And, do you have snow?

we have snow and ice. Lake Kasshabog

Northern Indiana, no snow, sun!

im in Ontario in Severn Bridge .we have some snow but lake not frozen over yet

Sun is great!

Buffalo, New York. No snow just yet!

Adirondacks in upstate NY, some snow and lakes are iced over! 12F/-11C this morning

Hi everyone! I'm joining from Keuka Lake -- we have snow (and starry stonewort...)

Rochester, VT, and no snow, but it is COLD!

The literature review is a really helpful resource. Thanks, Mike!

Buoy or boat bumper on the end of the rake toss rope helps if you lose your grip on the rope.

Thanks, Nicole!!

Haha! Great idea, Bruce. I've been there, done that!

Great idea, Bruce!

In Ontario we also have EdMaps … Run by Our OFAH Invasive Species Unit for sightings that citizen scientists can pin points on a map of sightings - vetted by staff there afterwards

Simcoe is 280 sq miles … largest inland lake in southern Ontario … SS is spreading rapidly there throughout shallow sections

Lake Scugog, just to the south east of Lake Simcoe in Ontario also has done very extensive SSW research and will connect with you right after this.

EdMaps is great, too! Reporting is the key! And, i think that other mapping programs like iMap and the NAS software 'speak' to each other and share data

Simcoe has been treating for SSW over multiple years, correct?

Indiana DNR has recommended a wait and see approach rather than rapid response!

SSW was just added to EDDMapS in the fall of 2020. David is actually working with the Ontario Invading Species Program to get our data uploaded to EDDMaps

Please note, no starry stonewort in Jack Lake, Ontario, only chara.

re Simcoe … Brian Ginn could answer better … but to best of my knowledge just mechanical harvesting for a variety of plants every fall in some areas

Treating isn't really the right word. Lake Scugog has been working with various Universities and has just completed a three year research project on SSW. We found it first in 2015.

I see. Canada has strong impediments to chemical treatment, correct?

For the most part yes …

Yes, especially those lakes that are part of either the Trent Severn Waterway/Parks Canada or the Rideau Canal/Parks Canada systems.

We are using it (Diquat) for water soldier in the Trent … system and have used it successfully in the Black River (a trib of Lake Simcoe) and some isolated ponds

Very special allowances.

It seems to be staying in the deep water and not impeding the shallow shorelines so not causing any problems yet.

Great presentation, thank you. I am sorry I have another meeting to attend.

Thank you, Sheelagh!

Thank you this was very good, unfortunately I have another meeting to attend.

Post your question here, please

What does it do for long term fish populations?

Is there any management technique that has been proven successful/

Have the embayments along the St. Lawrence River been sampled recently for SSW?

does the Cayuga Lake Watershed Network help at all in surveys? They are doing a lot with rake tosses for Hydrilla.

Hi, Lynn- yes, CLWN is a strong partner of the SSW Collaborative and we have volunteers taking rake tosses from Cayuga Lake

thanks. very informative.

We have had real good success with shade mats for water soldier

small 10X 10 matts

Are the shade mats installed on the surface of the water?

yes in some areas- we had better success by sinking them right over the plants

Ok. Thank you!

At the south end of Canandaigua Lake, it appears that SSW outcompetes EWM.

easier to manage that way too- wave action disrupts them otherwise

Any connection to climate change or salt levels?

Can you speak a bit more on the success of mechanical harvesting for this species? Is fragmentation not a significant issue?

Interesting, over the years of harvesting, we have had a greater increase of Canadian waterweed rather than SSW. Going from about 70% SSW down to about 40%SSW to about 50% CWW.

Great job - Thank you!!

Thanks for a great presentation!

Thank you!
