It was estimated that reduced rabbit populations as a result of RHDV would increase agricultural production by $600 million annually, including about $300 million for the wool sector, $150 million for cattle, $80 million for cropping and $70 million for sheep meat17. PestSmart is managed through the Centre for Invasive Species Solutions (CISS) The community also suffers indirectly, as they might pay higher prices for rabbit-affected commodities (such as wool)2 or bear the loss of ecosystem services at the catchment scale3.
