Welcome to UCweeds.org!
is the website for the Utah County Coordinated Weed Education and
Management Area; a group of state, private and federal organizations
and agencies who have partnered to prevent the spread and increase
awareness of invasive plant species.
If you see weeds, visit UCweeds!
UcWeeds.Org is very proud to announce our brand new, report-a-weed
section that allows anybody who has seen non-native or invasive weeds
in Utah County, to report them to us. Because, the hardest part about
fighting invasive weeds is, simply, knowing where they are.
It's just a weed! So what?
Sure, its just a weed, many of them are quite pretty and look like beautiful wildflowers. How bad could they be?
the problem with plants transported from other environments is that
they out-compete native plants for water, light and space. Many times
animals can’t or won't eat the invasive plant, which can result in them
not eating enough to survive the winter. Or worse yet, sometimes
invasive plants are poisonous to native animals. The yellow-starthistle
is so poisonous to horses, that if a horse eats this invasive plant, it
will probably die. Many invasive plants, such as cheatgrass, come up
earlier in the spring, using available water and resources, but then
dry out quickly and become very flammable, increasing the chance and/or
size of a wildfire. These weeds also increase the frequency of wildfire
which prevents other more beneficial native species from becoming
reestablished after wildfire.
species are the second leading cause-after habitat loss-of species
being listed as endangered or threatened, and infest more than 100
million acres across the United States," said Lori Williams, executive
director of the NISC. (National Invasive Species Council)

Wildflower seed mixes include some wicked bloomers.
The seed packets have labels with romantic-sounding names such as
meadow mixture and wedding wildflowers, while others tout backyard
biodiversity and make reference to Earth Day. When growing 19 such
packets of wildflower mixes, however, University of Washington
researchers found that each contained from three to 13 invasive species
and eight had seeds for plants considered noxious weeds in at least one
U.S. state or Canadian province.
And what makes it nearly
impossible for gardeners who want to be conscientious is that a third
of the packets listed no contents and a little more than another third
had inaccurate lists. Only five of the 19 correctly itemized
"I can't recommend using any wildflower seed
mixes," says Lorraine Brooks, who did the work at the UW's Center for
Urban Horticulture while earning her bachelor's degree.
