International Experience around Pivot Irrigation
International experience in the US and NZ providing some basic information about the planting of trees and companion non-commercial trees on irrigated farms. Full advice and information on species and planting specific to Tasmania can be obtained from other publications and by contacting PFT listed on this website.
Tasmanian farmers and advisors thoughts on Agroforestry and trees on farms in Tasmania
Integrating trees into farmland provide many benefits, from increases in agricultural yield, property value and a range of other social and environmental benefits that are rarely accounted for. Interviews were conducted with 44 Tasmanian farmers to better understand farmer perception to trees on farms in Tasmania.
Perception of trees on farms - results from Victoria
To understand farmer perception to trees on farms, and particularly the benefits and barriers to planting, interviews were conducted in Victoria, by CSIRO, with 22 farmers and 4 farm advisors in 2018. The results were broadly consistent across the different industries and regions and with the results from interviews in 2017 in Tasmania with 44 farmers and farm advisors.
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 increased pasture production by 30% (Case Study 5)
During the spring of 2017, stock were excluded from the 'Formosa' paddock and pasture was measured and mapped across the paddock from sheltered to unsheltered areas. Pasture productivity was on average 30% higher in the sheltered half of the paddock compared to the unsheltered area.
Agroforestry improves enterprise income (Case Study 4)
The benefits of agroforestry to the farming enterprise include diversification, increased productivity and improving the sustainability and resilience of farm systems.
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.
Planting trees in the harsh Midlands provides much needed shelter (Case Study 2)
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%).
