Parafence has performed very successfully at numerous locations in Tasmania, where it has been deployed to protect the leading edge of horticultural crops from wind damage.  The product works as a wind filter, so it reduces the damaging effects of high winds, while allowing enough air to flow through the product, so that wind turbulence does not create a problem further into the crop, like would be the case with a solid structure.
