Evidence has shown that integrating biodiverse plantings of native trees and shrubs into farming systems can mitigate risk, enhance productivity and provide an array of valuable ecosystem services besides. The proven benefits of this ‘natural capital’ are rarely translated into demonstrable economic value, which means property valuers and banks still tend to consider native vegetation and other natural features on farms as having ‘zero productive value'. Greening Australia are inviting sheep producers to participate in a nationwide survey that aims to put a dollar figure on the benefits native vegetation provides for lamb survival in Australian sheep production systems. Participate in the survey here.
