Common names for the plants include grasstree, grass gum-tree (for resin-yielding species), kangaroo tail, balga (Western Australia), yakka (South Australia), yamina (), and black boy (or "blackboy").
North America is considered a hotspot for many invasive species of grasses, which threatens all of the endangered native grass species and potentially threatens other grass species. Conservation tactics and management policies can help prevent invasive species from taking over and driving native North American plants to extinction.
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season.
If you do insist on keeping your yard cleaned up, the NWF recommends doing it the old-fashioned way, because leaf blowers pollute the air.
Root barriers are also used to separate plant roots from each other. In particular, walnut trees secrete the chemical juglone which is toxic to other plants but the use of root barriers can prevent the yield reduction that would normally occur when walnut trees are alley cropped with maize as often occurs in the American Midwest.

Wind throw is the toppling of a tree due to the force of the wind, this exposes the root plate and adjacent soil beneath the tree and influences slope stability. Wind throw is a factor when considering one tree on a slope; however, it is of lesser importance when considering general slope stability for a body of trees as the wind forces involved represent a smaller percentage of the potential ...
Roads, sidewalks and foundations can all suffer structural issues from tree roots. [7] Several methods of control have been attempted, from barriers to encouraging growth in desirable directs. Selection of plants with root systems that will not conflict with nearby structures is the most effective method of damage control.
Xanthorrhoea australis, the grass tree or austral grasstree, [1] is an Australian plant. It is the most commonly seen species of the genus Xanthorrhoea. Its trunk can grow up to several metres tall and is often branched. In certain Aboriginal languages, it is called bukkup, baggup or kawee. [1]
