Giant salvinia

A few spots in NWLA are getting killed with it.

Lake Bistineau will be a memory in < 5 years.

Clear Lake/Smithport Lake along with Wallace Lake (potholes compared to others) are done.

Other bodies have the salvinia but they are large enough that it just sits in the trees.

They have been spraying bistineau and working on a weevil plan, drawdowns, all that good shite. Its gone IMO.

We have it where I live. Open lakes is no problem as the wind pushes it to shoreline and spraying twice a year does the job. A couple lakes around Lafayette have the weevil and they really do a number on it.

The problem areas are in North Louisiana. Its just a bit too cold for the weevils but not quite cold enough to kill the salvania. On top of that, efforts to clear large pathways in many of these heavily treed lakes has met with resistance from "Tree Lives Matter" folks. Creating these wide pathways lined with prevailing winter and early summer wind patterns would make spraying many times cheaper and more effective.

It's truly sad. There are places I won't be able to take my kids that are taken over with hycenth that I cut my teeth on (unless something changes). Thinking about the possibility of losing more sucks.

We put out tons of weevils, it worked to a degree. It only took a high water event to move more in.

where can you get these weevils and how much do they cost?

The only things that help with giant slavinia are high water and cold winters with prolonged freezes (which are pretty rare these days). All of the other stuff they've tried has had little to no affect. Here's a picture of Caddo in Jeems Bayou from a couple of summers ago. It's some bad stuff.

Bistineau is wrecked with the stuff. Caddo has more open water and flushes better although parts of Jeems and the texas side have been thick too the last few years. If the weevils could tolerate the cold we might have a shot. Texas was trying to harden them to cold but I don't know how the program has progressed. South louisiana is likely far south enough that the weevils can overwinter. I know they've had success in parts of south central texas with weevil control. We need a 1983 type winter followed by a high water spring and some type of successful control program to get back to even against this stuff.

That shite renders an area unfit for ducks in a hurry

Weevils have worked in St. Bernard for us

Tensas has bot seen it yet thankfully


So far that is most impact full invasive species


We saw that shite 4 miles sought of pointe aux chenes landing sat
