Colstrip Biological Weed Control Program
is funded by PPL and Western Energy. They run their program
the county and companies put the money in the county fund.
They currently have two sites, one for spotted knapweed, and
one for Canada thistle. They made the site for Cyphocleonus
larger, they are working on that now. They
will transplant more into it, and release the insects that people
sent them last fall into that site. They also have a tent with
Larinus minutus. They
have released insects there and hope to gather them this
summer, so they can release on surrounding sites.
They have looked at spotted knapweed in the area and many of the plants
have holes in the seed heads. There aren't any sites large
enough to release Cyphocleonus
at this time. The leafy spurge
insects (flea beetles) that Jewel Davenport collected
in Grass Range with the Whitehall Project, were released on the
reservation. She has a past
student that is going to the site with her this summer to look at
it. They are trying to get (Canada) thistle insects for the town
and golf course because the town and golf course is
full of it. It is also abundant on
the creeks in that area. Jewel will hire a couple of students
soon, and they will work
on transplanting and working in the sites. This summer they plan
on doing a survey on the area and record what
they see as far as weeds.
are working with Rosebud Watershed
Group on the thistle project.
