This web-based interactive map has been designed to increase awareness of the invasive weed species currently found in the Lake Tahoe Basin and assist in the early detection and reporting of new infestations. With your help in reporting new infestations, we can control new populations before they become large and more difficult and costly to control.

Areas shaded in green on the map represent the different communities within the Basin, while the points represent different invasive weed species that occur within each of our communities. Please note that these points do not reflect exact locations of infestations, but rather species that are representative within a given community. Please read the map instructions for more information on how to navigate and interact with the map and report an invasive weed location.

Within the box, you can view the weed species that occur at the location of your click under the "Weed Point" tab, and the community information under the "Weed Community" tab. Note that clicking on or near multiple weed points or communities will result in multiple results displayed in the info box. To close the info box, click on the small x in the upper right corner.
