Agencies try to root out invasive species from Tahoe
By Max Neale
On April 5, the Lake Tahoe Aquatic Invasive Species Coordination Committee hosted its first Aquatic Invasive Species public forum at the U.S. Forest Service building in South Lake Tahoe. The event featured expert speakers from the Tahoe Regional Planning Agency, U.S. Fish and Wildlife Service, U.S. Department of Agriculture, UC Davis, and was facilitated by the Tahoe Resource Conservation District. Topics of discussion included AIS threats nationwide and basinwide, the latest research on Lake Tahoe AIS, past and upcoming control management efforts and upcoming changes to the watercraft inspection program.
Steve Chilton, Lake Tahoe and Northern Nevada AIS coordinator for the Fish and Wildlife Service, described AIS, such as the Asian clam and Eurasian water milfoil, as “a serious problem for Lake Tahoe, both ecologically and economically.” Chilton explained that in the United States AIS cause hundreds of millions of dollars in damage and control costs annually.

He cites Lake Mead as an example where the quagga mussel, first discovered there in 2007, has spread to nearly every corner of the lake and is now adversely affecting the valuable striped bass fishery. The goals of Lake Tahoe’s AIS Management Plan are to prevent new invaders and to monitor, control and eradicate those that currently exist.
Ted Thayer, manager of TRPA’s AIS program, presented on the history and structure of Lake Tahoe’s research and management efforts. Thayer emphasized the wide reaching impacts of AIS, which have extensive economic, ecological, and social consequences. He also described the importance of Tahoe’s collaborative approach to management, which involves more than 50 organizations and agencies working together to prevent and control AIS. The efficacy of this partnership was recently recognized with an award to commend the excellent work being done in the Tahoe basin to combat and prevent AIS from the U.S. Forest Service headquarters in Washington, D.C.
While last week’s forum highlighted past successes, it also addressed the many challenges that currently face Lake Tahoe. Patrick Stone, senior wildlife biologist with TRPA, spoke to the history of aquatic plant invasions, current control methods, and the importance of the watercraft inspection program. “The [watercraft inspection] program is designed to stop all AIS from entering Lake Tahoe and also to prevent their spread within the Basin.”
Ken Kasman, director of watercraft inspections at TRPA, further described the program as the way best way “to lower this risk of new invasions while still allowing access to the lake.”
Watercraft inspection fees for the 2011 boating season will range from $30-$100, depending on vessel size. According to Kasman, inspection fees raise only 29 percent of the funds necessary to operate the inspection program. Federal funding from the Fish and Wildlife Service, state and private sources provide the majority share.
Several researchers, including Lars Andersen from the USDA, Geoff Schladow from the UC Davis Tahoe Environmental Research Center, and Jay Rowan of the California Department of Fish & Game, outlined research projects for the 2011 field season. Highlights included two pilot projects for control of the Asian clam, a dye study to test the feasibility of aquatic herbicide use in the Tahoe Keys, and a project that aims to reduce the populations of largemouth bass and bluegill, two species of warm water nonnative fish present in the Tahoe Keys.
During the public comment period several people and local business owners raised concerns about boat inspection protocols and the potential economic impact of a reduced bass fishery in the Keys.

Thanks so much for filling us in on this meeting. I wish I knew it was occurring in advance, as these experts tend to be worthwhile to listen to. I wonder many times if we are just throwing $s/resources at wishful thinking.
It is very hard for me to not believe if the keys are mostly restored to the wetlands filter of the largest river entering our great natural resource of Lake Tahoe, a huge amount of issues related to water quality will not be significantly reduced. As for invasive species, northern Europe was once frozen solid; people of northern European decent hence are an invasive species, that is life on planet earth. As far as I know, every glacier on the planet is receding. This leads me to believe the planet is warming. Is it correct to assume, without invasive species or mutations, life will be reduced as we know it, will be to warm for established species?
I know this is much more complicated than this, hope to see any future informative meetings. Thanks for the mention of “Tahoe RCD newsletter”. http://www.tahoercd.org/index.php?page=contact-us is the page to sign up for a quarterly e-newsletter.
Notice of these meetings, well ahead of time, would garner the most cooperation. We’ll all pay for this process, so why not make an important like this well known so people can plan to go? Don’t expect the HOA to do the distribution.

On top of that, there was an ad about the event running on LTN.
What more would you have wanted?

Nice article. Cesar Chavez would be proud.
Oh my Admin – you really believe an article in LTN which speaks about the meeting on April 5th(which I understand was cancelled) will really do it for notification? How many people who might very well be interested in this subject are going to go to LTN for notification? Glad I don’t live in the Keys, but if I did I’d be very concerned. They will be paying big money, so why shouldn’t they have been sent notification about the meeting on the 13th. In lieu of the association doing the right thing, then something other than on-line would have been helpful. Not everyone has a computer, nor do they have time to cruise around on line trying to find information.
If you read the first three words of the story, it says the meeting took place — so your theory, TaHoGal that it was canceled, is wrong. You and another commenter said it would be nice to have advance notice. You obviously read Lake Tahoe News. LTN showed how it at least provided advance notice. You would probably the type to complain if a nonprofit (TRCD) or taxpayer entity (Lahontan) sent printed material to every residence — since you wanted advance knowledge of that meeting too. If you are interested in a public agency’s meeting, agendas are posted 72 hours in advance. I can’t think of one that is not online. And all are at the place where they meet — per the opening meeting laws.
I will echo the Admin’s comments — really, what more do you want? The public at some point has to take responsibility for being knowledge about what is going in their community, state and the nation.
