The River Exchange will be hosting two upcoming events concerning the growing number of invasive plants in Siskiyou County. 
An Invasive Plant Roundtable will be held at the Stage Door in Mount Shasta this Thursday, April 30, beginning at 6:30 p.m.
Information on the threat of invasives will be presented by Jodi Aceves, Deputy County Agricultural Commissioner; Mike Hentz, Noxious Weed Coordinator for the USFS Klamath Watershed; and Petey Brucker of the Salmon River Restoration Council.
Mellen Colberg, a botany and wildlife biologist for the USFS, will moderate.
The event is free of charge and open to the public. 
River rafting round-up
Then, on May 9 at 9 a.m., River Dancers will set sail on the Upper Sac for a river rafting round-up of Scotch broom. “This will be a hard working mission to remove the Scotch broom along the river,” says Chantal McDermott of River Dancers. 
Tools for digging and extracting the Scotch broom will be provided by the Forest Service. Cost is $50.  Proceeds from the event will benefit watershed education and restoration projects by The River Exchange. 
Pre-register by calling River Dancers at 926-3517.
Siskiyou County is home to 2,635 native plant species, according to a River Exchange press release, and is recognized nationally as a “biodiversity hotspot.”
Approximately 320 non-native plants also grow in the wild in the area. Approximately 104 of these are listed as invasives on Cal-IPC’s California Invasive Plant Inventory Database. The River Exchange says “improved understanding of their impacts will help those working to protect Siskiyou County’s treasured biodiversity.”
Invasive weeds can interfere with ranching, farming, recreation and habitat conservation. Because many of these species are dispersed by human activities, knowledgeable citizens can help to prevent new weed infestations and combat those already in place.
