The citizen science database iNaturalist (www.inaturalist.org) has an increasing number of observations of the Shrubby samphire. Where these records include both a habitat photograph and detailed photographs that allow confirm of the samphire’s identification, they provide spatially explicit, dated records of the health of the habitat across southe...

Saline lakes are hypersensitive to changes in their water balance and therefore show amplified responses to climatic and land-use changes in their catchment. However, despite the resulting, often dramatic ecological consequences, saline lakes rank low on policy agendas as they are assumed to support few ecosystem services and low levels of biodiver...

Tecticornia arbuscula is a late successional tall samphire that provided nesting habitat for the vulnerable samphire (slender-billed) thornbill, Acanthiza iredalei rosinae. ). In 2014 and 2017 significant dieback events occurred that affected the population of shrubby samphire across southern Australia (Coleman et al. 2017). Ongoing bird surveys ha...

Mangrove recovery continues, at a very slow rate, in the hypersalinity impacted area at St Kilda. The ongoing occasional loss of mature trees leads to some concerns about how the many thousands of tonnes of salts crystallised in the adjacent ponds will be managed to prevent further impacts. The patchy recovery of the saltmarsh appears to be rel...

Mbay is a small coastal village located in the middle of the north coast of Flores. In daily life, the local people carry out farming activities, raising cattle and goats, as well as cultivating rice, corn and various kinds of tropical fruits and vegetables. This activity is supported by an irrigation system that is supplied from the Aesesa River....

The investigators examined the rate of recovery after a recent hypersalinity event (starting in December 2019) that killed Avicennia marina mangroves in South Australia’s Barker Inlet. Initially the aims of the study included determining the distance mangrove propagules would disperse through a standing forest of dead wood and the persistence of...

Identification guide for samphires found in the saltmarshes of the greater Adelaide and Fleurieu Peninsula regions. A replacement for an earlier guide, with extra information on saltmarsh flora and fauna, the blue carbon values of these habitats and several new drawings and photographs

A number of samphire species occur on the Eyre Peninsula that had either been rarely collected or had been determined under other species' names during the 20th century. After this was noted by staff from the WA and AD Herbaria, the regional natural resource management board had Delta Environmental Consulting conduct an expedition to gain some unde...

This pocket guide covers the samphires of the Eyre Peninsula region. Please take this guide to the plant, not the plant to the guide! Samphires are the dominant life form in our temperate saltmarshes, and the variety of these amazing plants reaches a peak in southern Australia.

An assessment of potential threats to Samphire Thornbill habitat in the northern Adelaide and Mt Lofty Ranges NRM Region. Identifying the rapid decline in Shrubby Samphire (Tecticornia arbuscula) throughout South Australia, most likely due to sea-level rise.

Plantings of Gahnia filum have been recommended in both the Local Recovery Plan for the Yellowish Sedge-skipper butterfly and Thatching grass (Coleman and Coleman, 2000) and the recent updated recovery plan (Coleman, 2015). The latter plan recommended that a study be undertaken to determine the insect loads on Gahnia filum, as many of the plantings...

This review and revision of the Local Recovery Plan for the Yellowish Sedge‐skipper butterfly and Thatching grass (Coleman and Coleman, 2000) is included within a larger, spatially extensive coastal project (the Samphire Coast Icon Project) being managed by Natural Resources – Adelaide & Mt Lofty Ranges. The YSS Butterfly is a host-specific butterf...

As a result of climate change, salt lakes on Eyre Peninsula are predicted to have shorter hydroperiods. Already there are salinity increases due to land use changes, so major decreases in biodiversity are expected. The likely situation is different however for the few lakes receiving waters via marine springs, with Seagull Lake, 20 km south of Stre...

This pocket guide covers the samphires of coastal Adelaide, the Northern Adelaide plains and the northern Fleurieu Peninsula. Samphires are the dominant life form in our temperate saltmarshes, and the variety of these amazing plants reaches a peak in southern Australia.

The seventy kilometres of coastline covered by the mining leases of the Dry Creek Saltfield (Ridley Dry Creek Pty Ltd) include a range of coastal and estuarine habitats rarely found so close to a large centre of population. The leases occur over land that hosts flora of local, State and National conservation significance. In particular, the salinas...

Delta Environmental Consulting partnered with Natural Resources AMLR in a study into shorebird management and conservation. The resulting shorebird management and conservation report provides information on how to protect shorebirds and their habitats in the region. The study found that there are a diverse range of resident and migratory shorebird...

Australia’s only federally listed endangered samphire, the fan or bead samphire Tecticornia flabelliformis (Paul G.Wilson) K.A.Sheph. & Paul G.Wilson, is a small deciduous forb up to twenty centimetres high that is generally found growing in monospecific patches on clay pans or sabkhas directly behind coastal barrier dunes or on salt lakes further...

Several areas known to support the samphire species, Tecticornia flabelliformis Vulnerable under the EPBC Act, have recently been protected through fencing along existing roads that cross the sabkhas. The fencing is part of the implementation of the management plan Summary of Native Vegetation and Threats to Ecological Assets - Middle Beach to Port...

A detailed manual describing a wide range of estuarine monitoring methods and the interpretation of results.

Assessing current monitoring of the Onkaparinga estuary and design of ongoing monitoring program.

Given that diatom assemblages are a well-recognised method of characterising the water quality in freshwater streams, it seems reasonable to investigate its applicability to solar saltfields. A summer collection of benthic diatoms was undertaken in the salinas of the Dry Creek solar saltfields in South Australia for this purpose. The facility input...

This is a management plan for the restoration of a tidally restricted Cove, north of Adelaide South Australia. It contains extensive historic documentation, research and modelling into the effects of tidal restriction, Coastal Acid Sulphate Soils, determining where different tidal wetland types will establish given changed inundation patterns and...

This report looks at the long-term health of sediments in St Kilda Bay, South Australia, including human health concerns around the release of hydrogen sulfide. Results of sediment testing and macroinvertebrate assessments are presented. Theories as to the cause of the issues are proposed, along with potential solutions.

Vernal pools and wetlands are the ephemeral pools that appear in the wet season, typically late winter and early spring (hence the name), although the few that occur in the tropics occur during the monsoon. The impermeable layer allows the pools to retain water much longer than the surrounding uplands, but the pools are shallow enough to dry up eac...

The Yellowish Sedge-skipper Butterfly, Hesperilla flavescens flavia Waterhouse, was described in 1941. At that time it was collected from Henley and West Beach, as well as north of Adelaide where it was found in the swampy coastal areas west of Bolivar and Virginia. A small yellow and brown butterfly, the Yellowish Sedge-skipper Butterfly is restri...

Use of a computer GIS package to study aerial photographs of North Arm Creek (1979-1993) confirmed previous studies suggesting a landward migration of the grey mangrove, Avicennia marina, but seaward progradation was also apparent. Samphire communities were reduced in area by nearly two-thirds, with the majority of the lost area overgrown by mangro...

Trials conducted at Dry Creek, a solar saltfield north of Adelaide, Australia, indicate that manganese, as manganous sulphate, can increase both the purity and strength of salt crystals grown at an ambient or neutral-slightly acid pH range resulting in a salt suitable for high purity uses. The improved load bearing strength of the crystals indicate...
