Weed Week Challenge

Native wildflowers aren’t the only plants that respond to fire--sometimes weed seeds sprout or blow into burned areas. Some can even increase the frequency of fire in the future, or impact how native plants recover, so it’s important to track non-native species’ response too! Sunday, June 5th is the start of Invasive Species Action Week(June 5-13) and we will be partnering up with the California Invasive Plant Council (Cal-IPC) and the California Department of Fish and Wildlife (CDFW) to bring you all some new prizes to win during our weekly challenge!

Challenge Details:
Starting this Weekend, we encourage you all to go out and make as many observations as possible in any of the burn sites. There will be 5 opportunities for participants to win a CAL-IPC hat! Here are the rules for each category:

Most observations of non-native plants
Most identifications of non-native plants
Top observer of Spanish, French, Scotch or Portugese broom
Top observer of Cenchrus setaceus/Pennisetum setaceum, fountain grass
Top observer of Centaurea solstitialis, yellow starthistle

In addition to the main 5 winners, we will also be holding a raffle for those who have joined the project so far and made at least one observation of a non-native plant during the challenge! We will be raffling out 10 stickers and 10 luggage tags to 10 randomly selected winners! Just remember to join and trust the project before the end of the competition!

Best of luck to everyone!
