The status and conservation of shorebird habitat in South-east Tasmania

LB Parr-1988-01-01-UTAS Research Repository

TL;DRAbstract

Census data from 11 sites of shorebird habitat in South-east Tasmania from the 1960s, 1970s and 1980s were examined qualitatively and by using analysis of variance techniques. The aim was to establish whether the numbers of shorebirds using these sites as feeding, breeding and roosting habitat had changed over that time period, and to establish whether a relationship existed between observed changes in numbers and habitat alteration and loss at the sites. Of the eight sites monitored intensively during both the 1960s and 1980s sampling periods, the abundance of shorebirds decreased at three sites (Lauderdale, Orielton Lagoon and Sorell), no change in abundance was recorded at two sites (Clear Lagoon and Barilla Bay), and three sites (Pipeclay Lagoon, Calverts Lagoon and South Arm Neck) experienced an increase in shorebird abundance. At those same eight sites, the number of species present decreased at five sites (Lauderdale, Clear Lagoon, South Arm Neck, Sorell and Barilla Bay) between
