Insights from multi-species mammal

monitoring programs in the Upper

Warren, Western Australia

Adrian Wayne

Summary

Forty-two years of monitoring native mammals in the Upper Warren region in
Western Australia revealed increases in some species and a serial cascade of
declines of at least seven other species, including at least one local extirpation and a
pattern that suggests widespread community disassembly. The monitoring
program has highlighted the importance of using multiple methods, monitoring a
broad suite of species, having baselines and covariate data, developing a strategic
approach to adaptive monitoring, and how monitoring can make a difference to
management and conservation. This case study demonstrates the value of long-
term threatened species monitoring, and discusses the key challenges that must be
overcome to make the monitoring and conservation more effective.
