Several parameters representing aspects of vegetation, re, erosion and lacustrine productivity are investigated to compare the environmental changes of the historic period against those of the last 2000 years at Lake Keilambete in south-western Victoria. The average sedimentation rate post-dating European settlement was found to be c.2.5 times that of the analysed pre-European period and the nature of this sediment is distinctly different. Pollen representation was generally stable prior to the European period, but instability increased subsequently, re ecting the in uence of pastoralism and the increase in exotic plant species. An increased concentration (and variability) of carbonised particles in the historic period, despite the faster rate of sedimentation, suggests a complex change in the re regime of the region. The productivity of Lake Keilambete has varied in the past (e.g. it was elevated between c.1750 and 1250 years BP) but the response to European land use was diminutive. The expression of the quanti ed sedimentary parameters as average accumulation rates suggests a marked difference in the rate of landscape processes between the pre-and post-contact periods. The environmental change of the post-European period suggests that this landscape was particularly susceptible to the land-use strategies of the European settlers.

“…, citing Orchard's (1985) seminal work on the genus, interpreted similar recent increases in Myriophyllum pollen as evidence of mass-flowering following stranding of Myriophyllum beds. Arguably, similar patterns at other lakes from the region (Tower Hill, main lake, zone ML1;Cobrico Crater, central core;Dodson et al 2004) imply that recent changes in the aquatic flora are perhaps indicative of some regional phenomenon, rather than site-specific variability in terra australis 34…”

“…Palaeoenvironmental methods have been applied by Wasson and Clark (1985), Clark (1990), Boon and Dodson (1992) and Dodson et al (1993;1994a;1994b) to determine recent human impact on selected Australian environmental systems. This work is based on the approaches defined and used by Oldfield and Engstrom (Oldfield 1977;Oldfield 1983;Oldfield & Clark 1990;Engstrom & Wright 1984), among others.…”

Palaeoecological studies have identified the broad patterns of environmental and climate change in highland south-eastern Australia, but the detail of human impact on a variety of parameters and their interlinkages is largely missing. This study compares the erosion, productivity, fire and vegetation history in prehistoric and historical times at Burraga Swamp in montane rainforest in New South Wales. The known human impact is meagre; the major presently sustained impacts involve forestry in the surrounding sclerophyll forests and a low level of visits to the swamp by day-walkers. While no significant changes in the largely oligotrophic conditions or in fire frequency were detected, changes in erosion rates and some vegetation change can be attributed to impacts since European settlement. There has been a small decline in eucalypts and a loss of fern cover, while grasses, Urtica and exotic species have expanded. It is clear that upland sites are sensitive to environmental change including low-level human impact.
