Living shorelines aim to enhance the resilience of coastlines hazards while simultaneously delivering co-benefits such as carbon sequestration. Despite potential ecological and socio-economic benefits living over conventional engineered coastal protection structures, application is limited globally. Australia has a long diverse coastline that provides prime opportunities for using beaches dunes, vegetation, biogenic reefs, which may be either natural ('soft' approach) or with an structural...
Abstract The development and refinement of methods for estimating organic carbon accumulation in biomass soils during mangrove restoration rehabilitation can encourage uptake projects their ecosystem services, including those climate change mitigation, or blue carbon. To support the a method Australia under Emission Reduction Fund scheme we investigated; (1) whether data from natural mangroves could be used to estimate restoration; (2) modeling accumulation; (3) how modeled achieved over...
Hybrid living shorelines use a combination of engineered structures with natural ecosystems to achieve coastal protection and habitat restoration outcomes, added co-benefits such as carbon sequestration. Rock fillets constructed along eroding estuarine banks are designed accumulate sediment, establish mangroves, stabilise the shoreline. There is, however, lack data support whether rock achieving these goals. We used chronosequence determine their effect on mangrove development, bank...
Abstract. Savanna ecosystems are subjected to accelerating land use change as human demand for food and forest products increases. Land has been shown both increase decrease greenhouse gas fluxes from savannas considerable uncertainty exists about the non-CO2 soil. We measured methane (CH4), nitrous oxide (N2O) carbon dioxide (CO2) over a complete wet-dry seasonal cycle at three replicate sites of each uses: savanna, young pasture old (converted savanna 5–7 25–30 yr ago, respectively) in...
Abstract. We investigated the relative importance of CH4 and CO2 fluxes from soil termite mounds at four different sites in tropical savannas northern Australia near Darwin assessed methods to indirectly predict based on internal gas concentrations. The annual flux surrounding was dominated by with large variations among sites. On a carbon dioxide equivalent (CO2-e) basis, estimates were 5- 46-fold smaller than concurrent estimates. Differences between even greater, being almost three orders...
Australia’s rapid coastal population growth coupled with the increased risk of hazards driven by climate change creates an urgent need to start adaptation planning for future. The most common solutions protecting coast (seawalls, breakwaters) are expensive and non-adaptive (i.e., they be rebuilt, upgraded maintained in response a changing climate). There is international precedence development nature-based integration natural habitats such as vegetation biogenic reefs) cost-effective...
Abstract Novel designs of hard structures can address challenges to mangrove survival and serve as effective hybrid nature‐based coastal protection. However, a limited understanding how affect may lead ineffective applications techniques across diverse environments, potentially resulting in planting failures. To test ecologically engineered pods enhance facilitate natural recruitment, we deployed them at three sites experiencing erosion Victoria, Australia. We then planted propagules...
Abstract Disturbance associated with severe wildfires (WF) and WF simulating harvest operations can potentially alter soil methane ( CH 4 ) oxidation in well‐aerated forest soils due to the effect on properties linked diffusivity, methanotrophic activity or changes bacterial community structure. However, flux related such disturbances are still rarely studied even though frequency is predicted increase as a consequence of global climate change. We measured in‐situ soil–atmosphere exchange...
Abstract. Well-drained, aerated soils are important sinks for atmospheric methane (CH4) via the process of CH4 oxidation by methane-oxidising bacteria (MOB). This terrestrial sink may contribute towards climate change mitigation, but impact changing soil moisture and temperature regimes on uptake is not well understood in all ecosystems. Soils temperate forest ecosystems greatest globally. Under predicted scenarios, eucalypt forests south-eastern Australia to experience rapid extreme changes...

Despite potential ecological and socio-economic benefits living over conventional engineered coastal protection structures, large-scale application is limited a few locations globally.
