A revised look at tidal wetlands in remote northern Australia has uncovered a surprising new understanding of their responses to changing climate.
Mangrove and saltmarsh–saltpan communities appear to act as one combined ecological niche. As rainfall conditions vary, one seems to expand while the other contracts, with no net change in total area, provided all other things remain the same. So for example during decades of relatively high rainfall, mangroves expand while saltmarsh-saltpans contract, and vice versa. Despite all the pressures on tidal wetlands, it seems that moisture and salinity are often the dominant and predictable determinants of relative cover for these globally recognised habitats of tropic and subtropic regions.

Our Northern Hub Newsletter highlights what's going on in our research projects across northern Australia. It includes latest findings, what's coming up and what this all means for sustainable development and land and water management in the region.
The North Australia News Roundup is an informal monthly collation of news relevant to developing northern Australia. It aims to facilitate cross-sector and cross-region knowledge sharing, and more informed conversations and decisions about the future of the region!
