If you believe that you have detected a List A species  OR other suspected invasive plant species it is important to report your sighting as soon as possible.

• Completely fill out the Colorado Department of Agriculture's Weed Spotter Form and submit to Crystal Andrews via email or to our mailing address.
• Take pictures of plant details and habitat if possible to include with your completed  spotter form.
• Additional information such as a voucher specimen (sample) and a completed sample collection form  may be needed as verification.
• Verified species will then be added to the state database.
• Submitted spotter forms will also be forwarded to the appropriate weed/land manager such as the County Weed Manager  or USFS.

 

Identifying a target species to the best of your ability is extremely important in order to 1) keep the EDRR system from becoming bogged down from a large number of misidentified, common species and 2) protect rare, native plants from being mistaken as invaders.

 

• Please utilize the Colorado Department of Agriculture's fact sheets  and other resources ot match up key plant characteristics and rule out common look-alike species prior to submitting a spotter form.
• Utilize the CSU extension office in your region:
