Integrating biodiversity conservation in agricultural landscapes:
Intensification of agricultural production on hill country often involves clearance of native vegetation (tussocks, shrubs) and replacement by high producing pasture. But does this native biodiversity have benefits that are unappreciated and would be lost through clearance, and how important is this biodiversity for nature conservation anyway? These are both major knowledge gaps, which this research will address. The benefits provided to farming by native biodiversity (plants and animals) are poorly understood as is their importance to the resilience of farming operations over longer time periods, especially through difficult climatic events (e.g. drought or severe snow). Key benefits provided by native biodiversity to farming include shelter for new-born livestock, shade for livestock and pasture, nutrient cycling, water regulation and purification, soil stabilisation, carbon sequestration and pollination. This research will quantify benefits that native biodiversity provides to farm production in hill country farming systems through a mix of experimental and observational studies, quantifying benefits to farm production in terms of pasture growth, lamb survival, soil erosion, soil quality and legume pollination. We will also evaluate the native biodiversity present on our study farms in terms of the contribution it makes to broader nature conservation goals (e.g. as articulated through district and regional planning documents) and assess the long-term viability of this biodiversity under farming.
