OGDEN -- The U.S. Forest Service is reminding visitors to public lands that, if they take horses or other animals needing feed, they should make sure the hay, straw or mulch is certified free of noxious weeds and seed.
Acceptable feeds include certified weed/seed-free hay, hay cubes made from certified hay, and pellet feed.
Hay products that aren't certified as weed-free can spread invasive plants, including scotch thistle, spotted knapweed, perennial pepper weed, Russian knapweed, leafy spurge, musk thistle and hoary cress.
These noxious weeds continue to destroy the diversity of grasses and shrubs that wildlife such as deer and elk need to survive.
Violating the regulations could result in a fine.
A list of certified producers is at at www.ag.utah.gov. Click on the weed-free hay link under the heading "Favorites."
