13 – Insights from multi-species mammal monitoring programs in the Upper Warren^189B. penicillata were recognised, there was an increase in the amount and scope of
monitoring. This included reactivating monitoring sites that had extensive and
valuable historical data, but had been dormant for some time. The subsequent
increased spatial and temporal resolution of the monitoring revealed compelling
patterns and characteristics of the B. penicillata decline that helped identify the
causative agents (Wayne et al. 2015). Many research projects used the
monitoring program as a means of collecting data and samples, which led to
important and interesting discoveries. The involvement of individuals and
organisations in more than one of the three key elements of monitoring,
research and management, profoundly inf luenced the nature of these activities
and enhanced the conservation outcomes and prospects for the critically
endangered B. penicillata.
Beyond monitoring – making a difference
Regular analysis and reporting of the monitoring results is fundamentally
important. In the UWR, the initial recognition of a regional B. penicillata decline
at the end of 2005 came some 6 years after the declines had begun at some
monitoring sites and 2 years after a significant and sustained decline in the overall
regional numbers had begun. It took another 2 years to collate and harmonise the
various independent datasets to gain a more complete, region-wide understanding
of the nature of the declines (Wayne 2008).
Delays in the recognition of an important population change will result in
response delays. This in turn can reduce the viable intervention options available,
profoundly affect our understanding of the drivers of the change (e.g. Caughley
and Gunn 1996) and compromise the conservation outcomes for the populations
concerned. It may also increase the mitigation costs.
How and to whom important population changes are reported, and the
decision processes used to determine an appropriate response, are critically
important steps that affect the conservation outcomes for the imperilled species
and ecosystems involved. For example, first reporting declines of a threatened
species in a peer-reviewed journal to a scientific audience will delay
communication that is likely to miss the target audience of those best placed to
respond adequately and appropriately. On the other hand, peer-reviewed
publications can improve credibility, broaden awareness and result in external
pressure to act.
Other challenges
Some species declines around Australia and elsewhere have elicited responses,
while others have not. Identifying, understanding and overcoming obstacles to
implementing appropriate management responses are important. Some common
obstacles include:
