Nebraska Noxious Weeds

You Are Required To Control Noxious Weeds On Your Property
Pursuant to the Noxious Weed Control Act, section 2-955, subsection 1(a), to every person who owns or controls land in Nebraska, that noxious weeds being grown, or growing on, such land shall be controlled at such frequency as to prevent establishment, provide eradication, or reduce further propagation or dissemination of such weeds.

Noxious Weed Control
   
Saltcedar
Saltcedars have long tap roots that allow them to intercept deep water tables and interfere with natural aquatic systems. Saltcedar disrupts the structure and stability of native plant communities and degrades native wildlife habitat by outcompeting and replacing native plant species, monopolizing limited sources of moisture. Although it provides some shelter, the foliage and flowers of saltcedar provide little food value for native wildlife species that depend on nutrient-rich native plant resources. More
   
Purple Loosestrife
Purple loosestrife adapts readily to natural and disturbed wetlands. As it establishes and expands, it outcompetes and replaces native grasses, sedges, and other flowering plants that provide a higher quality source of nutrition for wildlife. The highly invasive nature of purple loosestrife allows it to form dense, homogeneous stands that restrict native wetland plant species, including some federally endangered orchids, and reduce habitat for waterfowl. More
   
Phragmites
Once introduced Phragmites invades a site it quickly can take over, crowding out native plants, altering wildlife habitat, and becoming a monoculture very quickly. Phragmites can spread both by seed dispersal and by vegetative spread via fragments of rhizomes that break off and are transported elsewhere. New populations of the introduced type may appear sparse for the first few years of growth but due to the plant’s rapid growth rate, they will typically form a pure stand that chokes out other vegetation very quickly. More
   
Leafy Spurge
Leafy spurge displaces native vegetation in prairie habitats and fields through shading and by usurping available water and nutrients and through plant toxins that prevent the growth of other plants underneath it. Leafy spurge is an aggressive invader and, once present, can completely overtake large areas of open land. More
   
Canada Thistle
Canada Thistle is declared a "noxious weed" throughout the U.S. and has long been recognized as a major agricultural pest, costing tens of millions of dollars in direct crop losses annually and additional millions costs for control. Only recently have the harmful impacts of Canada thistle to native species and natural ecosystems received notable attention. More
   
Musk Thistle
Musk Thistle is an aggressive, biennial herb with showy red-purple flowers and painful spiny stems and leaves. Each plant may produce thousands of straw-colored seeds adorned with plume-like bristles. More
   
Plumeless Thistle
Plumeless Thistle is an aggressive weed and is similer to the closely related Musk Thistle. Plumeless Thistle is a noxious weed in many states. It rarely flowers during its first year of growth. More
   
Spotted and Diffuse Knapweed
Spotted and Diffuse Knotweed are closely related and are noxious in several states. Diffuse Knapweed bracts are divided like teeth of a comb and have a distinct terminal spine. Spotted Knapweed lacks this terminal spine. More
   
Japanese Knotweed
Japanese,Giant and their hybrid Bohemian Knotweed and all cultivars and hybrids threaten open and riparian areas where it spreads rapidly and forms dense near monoculture stands. It dramatically reduces species diversity and alters habitat for wildlife. In raparian habitats F. japonica may also increase the risk of flooding and river bank erosion as it establishes monospecific stand that die back in the winter leaving banks exposed. Prolific rhizome and shoot growth can damage foundations, walls, pavements, drainage works, and flood prevention structures. More
   
Sericea Lespedeza
Sericea lespedeza (Lespedeza cuneata) is a long-lived perennial forb that grows well in grasslands, pastures, along roadsides, drainage areas, fencerows and other disturbed areas. Sericea lespedeza is an extremely aggressive invader of open areas. Dense monocultures of thickets are formed due to its ability to sprout from root crowns. Established sericea lespedeza plants will reduce or eliminate competing vegetation and restrict the amount of light reaching other plants. It readily escapes from cultivation into native grasslands and agricultural areas, and can seriously impact pastures and natural areas. More
