- Description: Monitoring migratory species can be extremely challenging. For example, millions of migratory shorebirds migrate from breeding grounds in northern China, Mongolia and Russia to East Asia and Australasia each year, traversing more than 20 countries while on migration. Studies within individual nations have identified rapid declines in many species, yet progress toward a fully unified scheme for continuous tracking of population change at the scale of the entire East Asian-Australasian Flyway has been slow. To reflect on lessons learned and consider how further progress might be made, we review some of the factors that have limited the full emergence of shorebird monitoring in the East Asian- Australasian Flyway, including fragmentation among multiple databases, low data readiness, inadequate metadata and gaps in survey coverage. We conclude that while technical solutions for many of these issues do exist, the biggest challenge is to navigate the significant organisational, socio-cultural and resourcing contexts of those people doing the monitoring. Technical solutions alone will not create a cohesive network of people whose local efforts are pooled to create robust flyway-scale monitoring. © 2021 Royal Zoological Society of New South Wales.

- Description: The critically endangered northern hairy-nosed wombat (Lasiorhinus krefftii) currently exists at only two locations in Queensland. Management, research and monitoring of the species at the main Epping Forest National Park (Scientific) population has occurred over the last four decades using a variety of tools, with the most complete dataset being provided by burrow activity monitoring over that period. Following a series of trap-based surveys in the 1980s and 1990s, wombat monitoring has employed DNA profiling of hairs collected remotely on sticky tape set at burrow entrances (since 2000), and passive infrared (PIR) cameras (since 2011). These techniques have produced a wealth of new information on the species. Using this new information, we aim to: (1) summarise the available demographic data and present new estimates using novel techniques for L. krefftii at Epping Forest NP; and (2) characterise reproductive patterns and their relationship with environmental factors for L. krefftii at Epping Forest NP. We find an ongoing increase in the population size at Epping Forest National Park, supported by healthy levels of reproduction despite periods of poor environmental conditions, notwithstanding the finding that cumulative monthly rainfall six months prior to sampling influenced birth rates. This trend suggests that the population will likely reach carrying capacity in the near future. It is timely to harvest the population to provide founders to a new site to establish an additional population, which will also reduce the risk of extinction and help secure the future of the species. © 2021 Australian Mammal Society.
