It is important to consult with your neighbours, since adjoining properties will need to manage tree roots if plantings are close to cropping areas. Current research on Gascoyne Research Station suggests that Casuarina cunninghamiana is the best tree species to use. Plant trees 1.5 m to 2.0 m apart within each row. Plant a minimum of two rows 4 m apart with trees diagonally offset. Prevailing winds in Carnarvon come from the south, so plant primary windbreaks along southern boundaries.
Single rows are suitable for secondary windbreaks.
Deep rip the site to encourage deep root systems. Use plastic mulch to reduce weed competition. Further details Further details on the design, planting and maintenance of natural windbreaks are available from Agriculture Western Australia's Carnarvon Regional Office.
