Between 1972 and 1999 the clearance of Tasmanian runs for crops, improved pasture and dams declined dramatically, although, since then, there has been clearance of some of the least-protected vegetation types. During a six-year period in the 1990s some vegetation remnants in wool-growing country were cleared or partially cleared and a substantial number of properties changed ownership. Change in ownership was often associated with changes in management
of the remnants. Some changes were positive; more were negative. The vegetation characteristics of the edges and centres of the uncleared remnants did not change very much over the six years. Edge effects in remnants are shown to be very limited in penetration and largely related to ingress of nutrients from surrounding developed country. Mosses and liverworts, vascular plants and birds respond very differently to the characteristics and management of remnants. Small remnants in poor condition may, in some cases, be more important for the maintenance of native biodiversity than large remnants in good condition. The management of remnants for nature conservation should be primarily directed towards the maintenance of populations of threatened species, not improvement in condition.
