CA: State To Combat Invasive Weed Choking Contra Costa Delta (Egeria Densa aka Brazilian Waterweed)
CBS5 ^ | 3/16/11 | Dave Padilla - KCBS

Posted on 03/16/2011 10:27:53 AM PDT by NormsRevenge

DISCOVERY BAY (KCBS) – Boaters and swimmers in the Sacramento-San Joaquin River Delta are finally getting some help from the state in removing a non-native plant that is flourishing uncontrollably.

The plant is called Egeria Densa, or Brazilian Waterweed. The South American aquarium plant is notorious for being almost impossible to eradicate. The problem is especially noticeable near Discovery Bay.

”There might not even be any room for boaters to navigate because it’s so thick,” said Gloria Sandoval of the California Department of Boating and Waterways. “And for swimmers, their feet could get tangled in the weeds.”

Starting next month, the state will use an herbicide called fluridone to try to control the weed from growing any further.

We can get rid of non-native plants, but can’t do anything about all the non-native peoples that have invaded from south of the border?

How ‘bout we remove all the invasive, non-native liberal transplants that have screwed up this state as well?

I live in St. Mary’s County Maryland.

I realise this is a non-native plant, but I would like to tell you a story about water and grasses.

50 Years ago in my youth our waterways were choked with native grasses.

Boats had trouble getting in and out of the creeks. It was so thck that they used older sickle bar mowers pulled behind boats to cut a channel through it.

The Government decided to do us a favor and get ird of the grass, they sprayed it and killed it all.

Now the crabs do not have cover for shedding and the oxygen content in the water is down. 50 years and the grasses still have not recovered.

Think long and hard before allowing the government to help you with these grasses, what will whatever they use to kill the non native grasses do to the native grasses, Try to learn from the mistakes of the Chesapeake Bay watershed.

Hmmm, maybe the pesticide will affect the Delta Smelt, and water can be restored to the Central Valley?

California? The same State that brought in the tamarask plant for “erosion control”? The same tamarask that is now choking the shorelines of the Colorado, Green, Snake, etc rivers and seriously depleting the water volume? Yeah. That State. What environmental disaster do those govt idiots plan now?

Yep, at a cost of $900-1400 per acre to spray it, there must be ways to take advantage of it's bounty.

They have this same issue in Southern California, but a different take.

The Orange County Water District has water rights for all water that is discharged from Prado Dam. Up stream of Prado the area is usually dry, but floods when it rains. This Brazilian grass drinks up literally tens of thousands of gallons of water and also prevents water from going into the water table (which is drinking water pumped out elsewhere). OCWD has spent tons of money to remove this grass so as to increase the amount of water flowing out of Prado dam.

The benefit? OCWD sells this water (at a profit) to OC users and at a much lower cost then MWD water.

Now this is different than at the Delta, but instead is based on logic and potential increased water flow where it is needed.

I hope it also kills off all the Delta Smelt.

FREE THE WATER, SAVE THE FARMS.

There are a few ideas here:

The US is so screwed up.
I recognized the name of this plant because a client has it as the main plant in his aquarium at work.
You can buy Egeria Densa online and have it delivered anywhere in the country for about $20.
Then it escapes when little Ricky dumps the aquarium with the dead fish in the local stream for a funeral, and the plant propagates like mad.

FYI: This picture is just fine, but I cannot see post #10. I have had problems recently with some of the pictures that you post. I know that others have mentioned this to you on another thread the other day. I use IE but not sure which version.

Lakes, ponds, and swamps throughout the deep south are being coked by another former aquarium plant that has gotten into local waters, Duckweed. It even showed up 2 years ago in a small decorative pond in my backyard.

After I posted, #10 became visible. I know that in times past, I have always been able to view your photo post.

Invasive species? Just think of it as evolution in action.

Uh, no thank you. I think of them as a cost foisted upon me by irresponsible importers so that they could save a pittance by comparison.

Most duckweed is native, contains 40 percent protein and is totally palatable by almost every existing herbivore.

No problem. It's just that I spent 7 hours today on my hands and knees weeding. I take these things seriously because I know from hard personal experience that they really are serious.
