“…The width of the riparian forest 'buffer' strip was a dominant factor in determining the degree of impact, with little effect of coupe slope or soil type. Time after logging has been shown to have a significant impact on changes to catchment yield and stream hydrology (Cornish 1993) and to yield of sediment (Grayson et al 1993) and infiltration of sediment into stream beds (Davies and Nelson 1993). Time was not, however, a significant factor or covariate in the present study, suggesting that significant recovery from logging impacts did not occur within a period of three to five years.…”

Impacts from the logging of Eucalyptus forest on stream habitat, macroinvertebrate abundance and diversity, and fish abundance were surveyed in Tasmania, Australia. Forty-five pairs of sites from 34 streams of 22.5 krn2 catchment area were each sampled once during summer in the period 1990-92. Each site pair consisted of an 'impacted' site downstream of a logging treatment and an upstream or closely matched 'paired control' site. Site pair treatments encompassed two logging methods (cable and conventional) with a range of riparian buffer strip widths (0-50 m) and included unlogged controls. Differences between site pair variables were used as test statistics for the detection of logging impacts. Logging significantly increased riffle sediment, length of open stream, periphytic algal cover, water temperature and snag volume. Logging also significantly decreased riffle macroinvertebrate abundance, particularly of stoneflies and leptophlebiid mayflies, and brown trout abundance. All effects of logging were dependent on buffer strip width and were not significantly affected by coupe slope, soil erodibility or time (over one to five years) since logging. All impacts of logging were significant only at buffer widths of <30 m. Minimum buffer widths for eliminating logging impacts on stream habitats and biota are discussed.

“…Megahan & Kidd 1972, Doeg & Koehn 1990, Fahey & Coker 1992, Davies & Nelson 1993, Grayson et al 1993). Fine sediments which are removed from the land in this way may find their way to coastal areas within hours/ minutes (Fahey & Coker 1992), particularly in association with flood events (Nichols 1977, Wheatcroft et al 1997, Wheatcroft 2000.…”

“…Impacts of forestry activities on Australasian streams include changes in stream hydrology (Vertessey 1999), alteration of stream bank stability and sediment retention (Davies and Nelson 1994;Bunce et al 2001), reduction in shading and increased water temperatures (Lake and Marchant 1990;Webster et al 1992), modification of organic debris and channel morphology (Davies and Nelson 1994;Bunce et al 2001), changes to stream sediment particle size distributions (Scrivener 1987;Davies and Nelson 1993;Bunce et al 2001) and changes in aquatic macroinvertebrate and fish assemblages and populations (Davies and Nelson 1994;Growns and Davis 1994). Despite these known changes to habitat, platypuses have been recorded in streams downstream from areas subject to logging (Grant 1991;Turnbull 1998).…”

This study examined the occurrence, relative abundance and condition of platypuses in the upper catchment of the South Esk River, in north-east Tasmania, Australia, and the impact of past forestry activities on the occurrence of platypuses in first order headwater streams. The main trapping sites were in twenty first order streams, eight second-fourth order headwater streams and one fifth order stream reach. Additional trapping was also undertaken in the South Esk River and farm dams. Sites were trapped during late spring/mid summer and early autumn. A total of 78 individuals were caught in the study area. Platypuses were caught at all sites trapped in the second-fourth order and fifth order stream reaches and in nine of the twenty first order streams. Catch success was greatest in the fifth order stream reach and lowest in the first order streams. There was a trend toward a higher proportion of juvenile/subadult males in the lower order stream sites. For the higher stream orders, a higher proportion of individuals was caught during the summer, however for the first order streams, a higher proportion was caught during the autumn trapping period.Information collected on the body mass, body length and condition of individuals indicated smaller individuals with a higher tail fat index in the lower order streams.There was a trend toward a lower occurrence of platypuses in the first order streams, which had been disturbed 15 years previously by forestry operations compared to first order streams with relatively undisturbed catchments. Differences in occurrence of platypuses were related to differences in the 'instream' and riparian characteristics of disturbed streams compared to undisturbed streams. Headwater streams form a large proportion of a river system. Although they provide more marginal habitat for the platypus than larger river reaches, their disturbance may be an important land management issue in the conservation of this species, particularly in river catchments where the species is impacted by other environmental changes or disease.
