We used data from long-term records (1989–2020) of the Friends of the Koala in north-east New South Wales to identify trends in 5051 koala admissions. Chlamydiosis was the main cause of admission. Overall, 35% of admitted koalas were released. We have provided a new outlook on the limitations and strengths of rehabilitation records for koala conservation.

We asked: will a koala released from rehabilitation re-join the wild population and survive? Using ear tag records, we sifted the 31-year set of 5051 koala admission records. Re-admission figures mostly fitted the pattern of first admissions, meaning that the released koalas had become part of the local koala population. Of the 270 koalas that were re-admitted into rehabilitation, 66% remained for more than 6 months in the wild. We conclude that rehabilitated koalas can survive long term in the wild.

New Caledonia is home to an extraordinary assemblage of endemic and, in most cases, endangered palms. We evaluated the population structure of three endangered, narrow endemic palm species, Burretiokentia koghiensis, Cyphophoenix nucele, and Chambeyronia houailouensis, to better understand the factors responsible for endangerment and how best to devise and prioritise actions to conserve these palms.

This review looks critically at the way the status of species is assessed. The current approach based on IUCN criteria is reactive when it should be proactive and include species that have or are increasing in abundance. Nonetheless, the 2020 Action Plan is an important report and will be used to promote the conservation of Australian birds.
