What Weeds are Considered Invasive Species in This Area?

The priority species for the Upper Granite Creek Watershed are:

   Dalmation Toadflax (Linaria dalmatica)

   Diffuse Knapweed (Centaurea diffusa)

   Russian Knapweed (Acroptilon repens)

   Spotted Knapweed (Centaurea maculosa)

   Malta Starthistle (Centaurea melitensis)

   Sweet Resinbush (Euryops subcarnosus)

   Scotch Thistle (Onopordum accanthium)

   Common Teasel (Dipsacus fullonum)

   Saltcedar (Tamarix ramosissima)

   Russian Olive (Eleaganus angustifolia)

Over the next few days we will go more in depth to each one of these invasive plants. As we move into fall, Prescott Creeks will be planning more invasive species work days. We hope you’ll join us in learning more about these plants and in helping to remove them from our watershed.
