The necromass of the Posidonia oceanica seagrass meadow: fate, role, ecosystem services and vulnerability. 136, 31–34. Environ. For example, some species such as Halophila ovalis, can be found from the tropical waters of Southeast Asia to the temperate waters of Western Australia and New South Wales (Short et al., 2010). Forest Ecol. Ecol. The restoration successes seen in Australia and New Zealand today largely come from studies on Posidonia and Amphibolis, as well as Z. muelleri in New Zealand (Figure 1). J. Phycol. J. Exp. Eelgrass recovery after nutrient enrichment reversal. While the EPBC Act does provide some provisions for restoration such as through species recovery plans, these are generally only for threatened ecosystems (of which seagrass is yet to become), and these plans are slow to develop. Whilst many types of habitat suitability models exist, the principle of spatial planning and suitability indexes can be expanded to include development of restoration suitability models which encompass not only the environmental and physical suitability for seagrasses, but cultural, logistical, and social data as well. doi: 10.1111/eva.12909, Miller, A. D., Hoffmann, A. Proc. These have ranged from small-scale pilot studies (e.g., Irving et al., 2010) to large-scale transplantation trials (e.g., West et al., 1990; Bastyan and Cambridge, 2008), involving both manual and mechanical planting (e.g., Paling et al., 2001), and a wide range of anchoring methods [e.g., artificial seagrass (West et al., 1990; Campbell and Paling, 2003; Matheson et al., 2017), biodegradable pots (Kirkman, 1999), and hooks or pegs (Bastyan and Cambridge, 2008)].

These include tying seagrass shoots to metal frames which are lowered to the seafloor (e.g., Transplanting Eelgrass Remotely with Frame Systems (TERFS), Calumpong and Fonseca, 2001; Wendländer et al., 2020), or to oyster shells (Lee and Park, 2008). doi: 10.7717/peerj.3114, Cussioli, M.

An Australian example from Western Australia’s Dampier Peninsula includes a collaboration between Western Scientists and the Bardi Jawi Indigenous rangers who have joint objectives to incorporate indigenous knowledge into the management of over 250 km of Kimberley coastline (Depczynski et al., 2019). Long-term trials involving the use of hessian bags placed on the ocean floor to aid natural seedling recruitment started in 2004, with many showing long-term survival (Irving et al., 2010; Tanner, 2015). doi: 10.3354/MEPS08925, Reed, D.

Losses have also been documented in New Zealand (Park, 1999, 2016; Inglis, 2003; Turner and Schwarz, 2006; Matheson et al., 2011), with one of the more significant examples being the disappearance of 14,100 ha of seagrass from Tauranga Harbor since 1959 (Park, 1999, 2016). 5, 121–135.

R., Moilanen, A., Francis, M., Elith, J., and Taylor, P. (2008). (2013). Whilst restoration policy is rapidly being embedded into international agreements (e.g., New Deal for Nature, Convention on Biological Diversity Conference of Parties 15 (COP), and climate change challenges for COP26 Glasgow), it is yet to filter down adequately into Australian and New Zealand state or federal government policies for seagrass restoration. “The seagrasses of New Zealand,” in World Atlas of Seagrasses, eds E. P. Green and F. T. Short (Berkeley, CA: University of California Press), 134–143. Geography Prof Takes on Seagrass Restoration Research Under New Grant. Bull. While increased temperatures and carbon dioxide concentrations associated with climate change could potentially increase growth rates in various species (Olsen et al., 2012; Koch et al., 2013), the increased frequency of extreme temperature and storm events is expected to increase mortality (Collier and Waycott, 2014; Rasheed et al., 2014). doi: 10.1002/fee.1991, Jordan, R., Breed, M.

But, much of what we know about seagrass restoration is buried deep in reports and permits, never finding its way into scientific articles. The DEP seagrass restoration program consists of three components: salvage, laboratory tissue culture and aquaculture. Cairns: James Cook University, 44.

Collaborative designing of restoration programs between researchers, managers, and the various community stakeholders would likely increase restoration success, as each of these groups bring their own unique (though sometimes overlapping) skills and experiences.
