Woody weeds (INS) research
Increasing densities of native shrubs in western NSW has been an issue that concerned landholders and rangeland managers for the last 100 or so years. About 70% of the Western Division of NSW is estimated to be affected by woody weed encroachment and is one of the major problems facing graziers. Woody weeds are native shrub and tree species that have encroached or regenerated densely following disturbance. Favourable weather conditions, changes in climate, overgrazing, altered fire regimes and combinations of these are thought to be the main causes (Westoby et al., 1989; Archer and Stokes, 2000; Eldridge et al. 2015). Turpentine (Eremophila sturtii), narrow-leaf hopbush (Dodonaea attenuata), punty bush (Cassia eremophila …show more content…
2009). Its impact on vegetation structure, pastoral productivity, land value and susceptibility of affected landscapes to further degradation has been well documented (Harrington et al. 1984; Noble et al. 1984; Date 1987; Wilson and MacLeod 1991; Noble and Hodgkinson 1992; Noble 1997; Noble and Walker 2006). However Eldridge et al. (2015) contend shrubs may reduce the adverse effects of grazing on soil properties albeit at the expense of livestock …show more content…
Seedlings less than 10 cm of all the species had high mortality. Once the height exceeds 10 cm mortality of budda and turpentine were very low or can regenerate rapidly after fire through regrowth (Noble and Walker, 2006) while that of mature mulga had mortality of over 90%. However, Hodgkinson (1986) and Noble et al. (1986) have shown, mortality of budda, turpentine and some punty bush increased significantly if a second fire was imposed one year later, particularly in the autumn. The success of fire is also dependent on the build-up of fuel for effective burning (Noble et al.

Corrections Can Be Made To Overgrazing, Over Cultivation, And Deforestation

nutrients, and minerals. Another method to help with soil erosion is to use fertilizers, as it replenishes the soil faster. Another big way to not have over cultivating issues is to have sprays that kill weeds, and not let it spread. Conditioning the soil, and protecting it by killing the weeds could help with over cultivating problems, which we face today. Over grazing is another problem that we’ve need to overcome, that can also lead to over cultivating. One of the main ways to solve this issue…

Erosion Conversion: Overcultivation, Overgrazing and Deforestation Essay

the “No-Till” method that permits a continuous cropping cycle, this is when freshly cropped fields are immediately treated with herbicide and then a special tractor then replants new seeds and fertilizers into the soil thus using the previous dead weeds and mulch as the ground cover. (Wright, 2011) Overgrazing can be corrected by designating areas for grazing as well as rotating livestock to different foraging lands to allow the previous grazed land to regenerate new plant life. Also requiring…
