| Abstract: |
This project involved collection of data (2001-2006) on small fauna species (& wombats) usage of the steep constructed drain crossing (Martins Washpool), two years after construction.
Objectives: (1) To establish a methodology for future monitoring of usage of fauna crossings over the Tilley Swamp Drain. (2) To collect baseline information on fauna usage of crossings a year after their construction.
It is apparent that larger faunal species (ie. wombat, kangaroo, emu, swamp hen, fox and deer) are utilising drain crossings, and house mice. What is less clear from this initial work is whether species moving between other habitat types, though M. halmatuorum tall shrubland (such as small skinks found at Transect 2), would successfully negotiate the drain crossing. This is an important concept given that species recolonisation of isolated habitats after events such as fire, may be prevented if the drain crossings do not facilitate such movement. The two critical elements in evaluating this will be continued monitoring over an extended time, and review of the season in which monitoring takes place to maximise chances of detecting species radiation on crossings.
Visual assessment of the regeneration of vegetation on the crossing should continue via annual photopoint survey. Use of the crossing may be restricted until an adequate amount of vegetative cover has established. The monitoring should be continued annually to assess the ongoing impact of the drain on small faunal movement in the vicinity of the Tilley Swamp Drain. |
