What To Do About New Weeds
If you know them, report them. Please report plants that are
new to an area if you don't need help with them. We need to map
Idaho's weeds to plan our strategy. Your reports are important.
If you don't know them, request identification.
What to send
Plants are identified by flowers, fruits, seeds, leaves,
stems, roots, and habitat. Send plants that have as many of
theses plant parts as possible. Several plants are better
than one plant.
How to send it
Place the plant specimen in a plastic bag between dry paper
towels without pressing or adding moisture and close the
bag. Store it in a refrigerator until mailing or bringing it
in. If mailing your specimen, mail early in the week so it
won't sit in a mailbox over the weekend.
Where to sendBring or mail your specimens to your nearest county
extension office or weed superintendents office. If the
county personnel are unable to identify the weed it will be
forwarded to the Erickson Weed Diagnostic Laboratory at the
University of Idaho for identification.
After you document them, get rid of them.
If a weed is new to the area
Record its position to enable adequate reexamination
of the site later.
This is extremely importantly: Do
this before you remove the weed!
If no flowers or seeds are present
Pull the weed and place it off the ground to dry
If flowers or seeds are present
Pull the weed carefully to prevent seeds from
falling. Place the weed in a plastic bag or
container to retain seeds. Dispose of weeds by
burning them or taking them in closed garbage bags
to a sanitary landfill.
