Agroforestry Agroforestry is incorporating trees into agricultural farms and is strategy of revegetation of the Department of Parks and Wildlife. This addresses the impact for the loss of habitat which results in loss of biodiversity, soil erosion and degradation and salinity problems in the wheatbelt. The Mallee trees, multi-stemmed trees, were chosen due to their growth in low-rainfall areas and they can help the biodiversity, water and soil.
These trees do not require fencing and help manage water, reduces wood weeds and reduces salinity in soil and wetlands. The farmers also must have at least 10% of their land covered in Oil Mallee trees. A property in Kulin planted 175,000 trees since 1997, and Yearling …show more content…
They use Mallee trees which fit in with the landscape and they help manage excessive water, the spreading of salinity, wind erosion and includes different species for different types of land. Professor Allan Barton studied in the early 1990s in Murdoch University and wanted to plant Eucalypt Mallee trees. They produce cineole for eucalyptus oil which provides farmers with another source of income. Now 900 farmers in 6 regions are involved in the program, from Esperance to …show more content…
This improvement reduces the public cost of natural management problems including salinity and water quality. The government provides $1.5 million in funding and grants for starting this program, although farmers must pay for maintenance for the trees and the machinery costs if any. The economic benefit of the trees is difficult to predict as it is for the long term.
Environmental benefits The Oil Mallee Program benefits the environment with concerns to the soil and the air. The revegetations results in a reduction of ground water and the water table, which reduces the salient issues in the soil. There is also an improvement in the soil management due to the protection of wind and water erosion of the soil. This improves the water quality through nutrients and salinity mitigation. The biodiversity is vastly impacted where the habitat is restored, encouraging animals to move around areas of agriculture and spreading the area for them to roam around in. The trees enhance the air quality, acting as carbon “sinks” that remove it from the air and containing it for the tree’s whole life. An Integrating Wood Processing(IWP) plant produces 5 MW from ~10 million harvested trees for electricity. When the trees are removed or harvested, they release the stored carbon back into the air, as well as loosing the habitat for the
