Reasons to Kill Scotch BroomĮffects of scotch broom shrub include competition with native forest plants. When in flower, the entire bush appears to be yellow.Īfter flowering, scotch broom will produce several dozen large pods that contain hard brown seeds. The flowers grow in clusters along the length of the stems. Scotch boom has tear-shaped leaves that grow in groups of three and mostly bright yellow flowers with occasional purple and red flowers mixed in. It is an aggressively invasive plant that will grow thickly rather quickly. Scotch broom is a deciduous shrub that can be found on the edges of wooded areas and in open fields. Once established, it is difficult to kill scotch broom. Scotch broom shrub was introduced as a landscape ornamental as early as the 1800’s, then used extensively for erosion control in public landscapes, such as roadside plantings, but quickly became a nuisance. Scotch broom control is difficult and often time-consuming, but worth the effort to get rid of scotch broom in the yard and forest. and responsible for the loss of a good deal of that areas’ timber income due to crowding out native species. It also includes advice on planning, holistic management, restoration and monitoring, as well as case studies that provide real examples of the successes and challenges of broom weed control.Though sometimes attractive in the landscape, the scotch broom shrub ( Cytisus scoparius) is a noxious weed in the northwestern U.S.

Scotch broom management is guided by the Broom Management Manual (PDF 15.4 MB) which provides information on biology, ecology and effective control of the brooms listed as Weeds of National Significance and highlights other new and emerging broom weed threats. The NSW National Parks and Wildlife Service (NPWS) uses an integrated approach to manage the weed, combining different control methods to achieve the best results and minimise its impact on native plant species. Managing scotch broom in our national parks The invasion and establishment of Scotch broom is listed as a key threatening process in NSW. Scotch broom has been listed as a Weed of National Significance and threatens many threatened species across NSW. The weed is spread mainly through cross pollination but also by animals, humans, farm machinery and in water ways, such as creeks. Scotch broom is one of the major weed threats to the alpine and sub-alpine areas of Australia. can alter fire regimes and restrict access to infested areas.can alter soils by increasing nitrogen levels.can provide shelter for pest animals such as pigs and horses, threatening native animals and plants.can infest agricultural pastures and reduce grazing areas.forms dense, shaded thickets which can inhibit and exclude native plant growth, leading to its complete dominance of the understorey and eventually the canopy.produces many seeds and can tolerate dry summers.It is highly invasive and spreads rapidly because it: It is particularly prevalent along the Great Dividing Range in areas such as the Blue Mountains, Barrington Tops, Kosciuszko National Park and the Central and Southern Tablelands. In New South Wales large areas of native vegetation have become infested with the weed. Plants usually have numerous straight young branches which gives the weed its common name. It occurs mainly in cool temperate regions, at high altitudes or along the edges of watercourses. Scotch broom ( Cytisus scoparius) is a large shrub, up to 4 metres, with bright yellow flowers. These three broom species are widespread across southern Australia, where they invade native vegetation and agricultural lands forming dense infestations that cause significant environmental and economic impacts. Scotch broom ( Cytisus scoparius), Montpellier broom or Cape broom ( Genista monspessulana) and flax-leaf broom ( Genista linifolia) were collectively listed as Weeds of National Significance in 2012. Several species of broom have been introduced to Australia and have become widespread invasive weeds in the southern states. Broom plants are a type of pea that have been cultivated for their ornamental features. The common broom, also called Scotch broom or English broom ( Cytisus scoparius) is a perennial shrub native to western and central Europe. Infestations are found in NSW, including alpine and subalpine areas.
