Saltcedar

Nebraska Noxious Weed beginning January 1, 2005. Nebraska's newest named noxious weed is beginning to find its way into the wetlands of Southwest and Central Nebraska. It can be found along the Platte River, including areas in Eastern Nebraska (the mouth of the Platte). This perennial tree, or shrub, spreads with highly viable seeds and plant parts, quickly forming a monoculture in the infested area. Mature plants can absorb up to 200 gallons of water per day, giving it the ability to dry up creeks and small lakes.

Purple Loosestrife

Nebraska Noxious Weed since January 1, 2001. A very agressive perennial that is infesting lakes, rivers, creeks, ponds, marshes, and other wetlands across Nebraska. This plant is, currently, the primary target of the LPWMA, due to its rapid spread along the Platte river system and its threat against beneficial plants necessary for wildlife habitat and food sources.

Phragmites

Listed on the NNWAC Watch List since 2002 This non-native plant is similar to a native common reed, but is rapidly spreading in waterways and lakes across Nebraska. This tall grass-like plant can grow up to 20 feet tall and form thick, dense stands making many areas inaccessible. This plant quickly forms a monoculture by pushing out native vegetation.

Leafy spurge

Leafy Spurge currently infests 325,000 acres in Nebraska. While pastures, rangeland, and right-of-ways tend to carry the largest infestation levels, other areas can equally provide habitat for this persistant, deep-rooted, invasive plant species. It can, and will, grow anywhere. In 1923, a botanical survey found this plant in York County. Since that time, it has spread into 82 Counties in Nebraska. Landowners and producers spend millions of dollars each year to control Leafy Spurge. This plant competes for water and nutrients while depleting grass and forage, which is utilized by livestock, wildlife, and recreationists.
