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), and

Russian Olive (Eleaganus angustifolia)

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