“…The species has previously been noted both in Tasmania (Callard et al 2011) and Victoria (Apthorpe, 1980), and, in agreement with our findings, often occurs as a near-monospecific fauna (Hayward, 2014). However, the species is not documented in lower latitude Australian sites (Berkeley et al 2008(Berkeley et al , 2009Cann et al 1993;Haslett, 2001;Haslett et al 2010;Horton et al 2003;Lal et al 2020;Strotz, 2015;Wang & Chappell, 2001;Woodroffe, 2005), which may suggest that the species has a preference for temperate salt marshes in Australia.…”

“…Ammobaculites exiguus has been noted to often reside within mangroves and in unvegetated muddy tidal and sand flats, which we find at Wapengo (Hayward & Hollis, 1994;Schröder-Adams,Boyd & Tran, 2014). Vegetation is influenced by elevation and salinity (Lal et al 2020); therefore we suggest that a combination of tidal frequency and duration as well as salinity and vegetation type exert influence on species distribution and diversity at our sites.…”

“…those found at all of their Northern New South Wales sites), which includes Ammobaculites spp., Ammotium directum, E. macrescens, M. fusca, S. lobata and T. inflata, we note the presence of all but A. directum in our regional training set. Furthermore, Lal et al (2020) encounter H. wilberti, but do not find it at every site. Previous literature shows A. exiguus can tolerate a wider range of salinities, usually around 20-32 ppt (Ostrognay & Haig, 2012;Schröder-Adams, Boyd & Tran, 2014), with preferences for mangrove and tidal flat environments (Hayward & Hollis, 1994;Schröder-Adams, Boyd & Tran, 2014).…”

“…Modern foraminiferal distributions at Lutregala and Wapengo are broadly similar to those observed in other studies from southeastern Australia and New Zealand. At four sites located near Wollongong, New South Wales, M. fusca, E. macrescens and T. inflata also dominate surface sample assemblages (Lal et al 2020).…”

“…The higher species diversity at Wapengo is a result of the presence of a greater number of Ammobaculites species. Lal et al (2020) suggest that high abundances of Ammobaculites spp. are correlated with a transition from mangrove to mixed mangrove and salt-marsh vegetation at the mid-elevations of the upper intertidal zone.…”

Development of a Training Set of Contemporary Salt-Marsh Foraminifera for Late Holocene Sea- Level Reconstructions in southeastern Australia

We collected contemporary foraminiferal training sets from two salt marshes to enable more precise and accurate proxy historical sea-level reconstructions from southeastern Australia. Combined with an existing training set from Tasmania, this new regional set consists of 112 samples and 16 species of foraminifera, of which 13 are agglutinated. Cluster analyses group the regional training set into a highelevation cluster, dominated by Trochamminita salsa, a mid-elevation cluster, dominated by Entzia macrescens and Trochammina inflata, and a mid-low elevation cluster dominated by Miliammina fusca and tidal-flat species. We develop transfer functions using local and regional training sets and assess their performance. Our resulting site-specific and chosen regional models are capable of predicting sea level with decimetre-scale precision (95% confidence intervals of 0.12-0.22 m). These results are comparable to other examples from around the world. When developing regional training sets, we advocate that the similarity in the environmental settings (particularly salinity) should be assessed as an alternative way of grouping sites, rather than simply using spatial proximity. We compare our findings with global results and conclude that salt marshes along microtidal coasts yield models with the lowest vertical uncertainties. Studies with the lowest uncertainties are located in the western Pacific and the western Atlantic, whereas those from the eastern Atlantic generally have larger tidal ranges and carry larger vertical uncertainties. Our models expand the existing region available for sea-level reconstruction and can be used to generate new late Holocene sea-level reconstructions across southeastern Australia.

Restoration of coastal wetlands has the potential to deliver both climate change mitigation, called blue carbon, and adaptation benefits to coastal communities, as well as supporting biodiversity and providing additional ecosystem services. Valuing carbon sequestration may incentivize restoration projects; however, it requires development of rigorous methods for quantifying blue carbon sequestered during coastal wetland restoration. We describe the development of a blue carbon accounting model (BlueCAM) used within the Tidal Restoration of Blue Carbon Ecosystems Methodology Determination 2022 of the Emissions Reduction Fund (ERF), which is Australia's voluntary carbon market scheme. The new BlueCAM uses Australian data to estimate abatement from carbon and greenhouse gas sources and sinks arising from coastal wetland restoration (via tidal restoration) and aligns with the Intergovernmental Panel for Climate Change guidelines for national greenhouse gas inventories. BlueCAM includes carbon sequestered in soils and biomass and avoided emissions from alternative land uses. A conservative modeled approach was used to provide estimates of abatement (as opposed to on-ground measurements); and in doing so, this will reduce the costs associated with monitoring and verification for ERF projects and may increase participation in blue carbon projects by Australian landholders. BlueCAM encompasses multiple climate regions and plant communities and therefore may be useful to others outside Australia seeking to value blue carbon benefits from coastal wetland restoration.
