Summary The New Holland Mouse (Pseudomys novaehollandiae) has a highly fragmented distribution in SE Australia. The abundance of the species is correlated with habitat succession. Optimal habitat has been identified as 2-3 years after fire, with population densities declining, sometimes to extinction, as vegetation ages. The species has become extinct at many locations in Victoria and, in 1999, was known to be extant at only four localities. When a remnant population at one locality (Anglesea) was considered at high risk of extinction, objectives identified to recover the species included determination of suitable habitat, development of ecological burning regimes, captive breeding and reintroductions. A GIS-based predictive model of habitat capability was consequently produced, areas of potentially suitable habitat for reintroductions identified and ecological burning regimes implemented. Experimental releases began in 2001 when predator-proof acclimatisation enclosures were constructed at two sites, selected on the basis of their habitat suitability. Small groups of animals have been released into, and subsequently out of, these enclosures. Movements and activity have been monitored by live-trapping, fluorescent dye and radio-tracking techniques. The results of trials have been assessed. Un-collared animals dispersed from the enclosures into surrounding areas, and gained weight, while initial releases of collared animals were less successful. Techniques and planning to improve future releases have been formulated. The future of the species in Victoria may be reliant upon the success of captive breeding and reintroductions.
