Impacts of windbreak shelter on crop and livestock production
The strategic addition of trees to farms produces a range of benefits including reducing land degradation, diversifying income streams, increasing biodiversity, carbon sequestration and increasing the national timber resource. The CSIRO have released a Review on the Impacts of windbreak shelter for crops and livestock. Agroforestry (the integration of trees into agricultural landscapes) has been promoted, in Australia and elsewhere, as a way to increase farm productivity by providing a wide range of benefits. Despite this, adoption of agroforestry in Australian agricultural systems remains low. To implement agroforestry, farmers must be convinced the benefits of including trees outweigh the costs. This review evaluates the available quantitative data on shelter benefits with emphasis on Australian conditions, identifies key research gaps and determines if there is sufficient knowledge to make accurate predictions about impacts on farm productivity.
This Review is available from the CSIRO Publishing website at a cost of $25.00 or please contact Private Forests Tasmania for further details.
Shelter improves Lucerne yield (Case Study 3)
Round bales of Lucerne hay were dropped in a paddock in the lee and outside lee of trees. Yields were estimated to have increased by up to 300% due to reduced wind speeds. Read more at the link below.

The Burbury family recognised the benefits of trees to their farming enterprise many years ago. Read more at the link below
Strategic tree planting to restore eroded gullies and improve farm productivity (Case Study 1)
Chris and Guiliana White have planted trees on their property, 'Willowbend', in the Huon Valley to improve farm productivity and biodiversity as well as produce timber. Read more at the link below.

Basalt to Bay - The Economic Benefits of Native Shelter Belts
The protection of existing native vegetation and the planting of shelter belts may provide a multitude of productivity and biodiversity benefits for farming industries. The value of shelter belts in raising agricultural productivity has been demonstrated in many countries suggesting potential improvements in crop yields (25%), pasture yields (20-30%) and dairy milk production (10-20%).
