Cost-effective landscape revegetation and restoration of a grazing property on the Northern Tablelands of New South Wales: 65 years of change and adaptation at ‘Eastlake'

Abstract

This paper describes the restoration of woody vegetation on my family’s grazing property, ‘Eastlake’ (1202 ha) on the Northern Tablelands of New South Wales. We commenced revegetating ‘Eastlake’ in 1981 to reverse the loss of native tree cover due to New England dieback and improve shelter for livestock and pastures to increase farm profitability. We treated the revegetation program as a long-term business investment and, apart from a 5-year period of overseas employment, have allocated annual funding in the farm business plan ever since. Our decision was based on the benefits of shelter to livestock and pasture production. Once we began revegetation, aesthetics, amenity and the positive impact on the capital value of the farm became important motivations. More recently, increasing the farm’s biodiversity and resilience, and conserving native flora and fauna, have also motivated us. Our strategy is to link upland areas of remnant timber with ridgeline corridors of planted vegetation to maximise shelter, minimise pasture production losses and provide dispersal corridors for fauna and wildlife habitat. Initially, we planted introduced species of tree and shrub, but now we revegetate mainly with native species, as well as fencing off remnant timber to encourage natural regeneration and direct seeding understorey species (mainly acacias) in degraded remnants and elsewhere. Our target is to increase the area of fenced-off and planted timber cover from 8% to 10% over the next few years, which will take the proportion of total effective timber cover from ~8% in 1980 to 18% of the property. The key lessons are to: (1) plan, prepare, plant the right tree or shrub in the right place for the right purpose, and post-planting care (the ‘4 Ps’); (2) integrate revegetation into the whole-farm business plan; (3) finance the work slowly over time with the aid of a spatial farm plan; and (4) adapt to changing circumstances, values and understanding. Research is required to help farmers understand the role of on-farm biodiversity in contributing to the health of the farm business, owner–managers and their families and the farm environment, as well as to regional economies, communities, landscapes and society more generally.
