1.6Benefits and Services of the Site


Benefits and services of Ramsar listed sites include:

  • non-anthropocentric ecosystem services derived from the site; and,

  • benefits to humans derived from the site (DEWHA 2008).

Table 9 and Table 10 are based on a format provided by DEWHA (2008) and list the identified benefits and services provided by Flood Plain Lower Ringarooma Ramsar Site.

Table 9: Benefits to humans provided by the Flood Plain Lower Ringarooma Ramsar Site with relevant components and processes.



Benefits provided

Ecological processes creating/supporting the benefit

Specific components and processes

Wetland products (fodder and water for livestock in Rushy Lagoon and leased crown land).

Maintenance of physical template for water retention and vegetation growth.

geomorphology

Provision of water for plant growth and livestock.

hydrology, water quality, climate

Replenish local groundwater (surface water/groundwater interactions not yet fully understood at the site).

Maintenance of hydrological stability.

hydrology, climate

Protection from erosion due to wind and wave action and currents.

Coastal shoreline and river bank stabilization and storm protection by site vegetation.

vegetation (terrestrial and wetland)

Water purification (including sediment and nutrient retention).

Removal and dilution of contaminants from diffuse sources (from grazing and catchment inflows).

vegetation (terrestrial and wetland), hydrology, water quality

Sediment (and attached nutrients) deposition in wetland basin stores and delays sediments reaching estuary.

geomorphology, water quality

Biological control of pests and diseases.

Support of predators of agricultural and other pests (for example, the site supports ibis which feed on grasshoppers, and eagles which feed on rabbits).

terrestrial vegetation, hydrology

Recreation and tourism

Provision of water regime to meet tourism/recreation needs, including recreational fishing, hunting (duck shooting), and nature observation.

hydrology, climate

Maintenance of water quality to meet tourism/recreation needs including recreational fishing hunting (duck shooting) and nature observation.

water quality

Maintenance of biotic communities to meet tourism/recreation needs, including recreational fishing hunting (duck shooting) aesthetic enjoyment and nature observation.

hydrology, water quality, vegetation (terrestrial and wetland)

Scientific and educational values, including possible palaeobotanical and palaeofaunal remains due to age of wetland type (in particular The Chimneys).

Maintenance of geodiversity, including deflation hollows, lunettes, and a dune barred lake (Bowlers Lagoon).

geomorphology

Maintenance of reducing environment required for preservation of palaeobotanical and palaeofaunal remains.

geomorphology, hydrology

Table 10: Ecosystem services (based on criteria) provided by the Flood Plain Lower Ringarooma Ramsar site with supporting components and processes.

Ecosystem Services

Ecological Processes Creating/Supporting the Service

Specific Supporting Components & Processes

Maintenance of rare and representative wetland type for the bioregion (criterion one).

Maintenance of landforms (and landforming dynamics) that provide the base for the wetland ecosystem in general including freshwater wetlands, the estuary and saltmarshes.

fluvial geomorphology, coastal geomorphology

Provision of fresh water (quality and quantity) for ecosystem requirements including freshwater wetlands, the estuary and saltmarshes.

hydrology, water quality

Provision of influx of marine waters for estuary and saltmarsh.

coastal geomorphology

Support for rare or threatened species (criterion two).

Provision of feeding and breeding habitat for green and gold frog, including permanent waters next to grasslands.

hydrology, water quality, vegetation (terrestrial & wetland)

Provision of feeding and breeding habitat for dwarf galaxias, including heavily vegetated seasonal wetlands close to permanent waters.

hydrology, water quality, wetland vegetation

Provision of feeding and breeding habitat for Australian grayling, including freshwater river for adults and estuary for recruitment and juveniles.

hydrology, water quality, wetland vegetation

Provision of feeding and breeding habitat for fairy terns.

geomorphology, water quality, fish (as food)

Supports populations important for regional biodiversity and/or at critical stages (criteria three and four).

Provision of feeding and resting habitat for eleven migratory bird species listed under CAMBA, JAMBA, ROKAMBA, and CMS.

geomorphology, hydrology, water quality, invertebrates (as food), fish (as food), Vegetation (as habitat)

Provision of feeding and breeding habitat for beach nesting shorebirds, including listed species.

coast geomorphology, invertebrates (as food) fish (as food)

Providing important habitat for Tasmanian mudfish at critical/vulnerable stages of its life cycle.

hydrology, water quality, wetland vegetation geomorphology

Providing important habitat for Tasmanian whitebait at critical/vulnerable stages of its life cycle.

hydrology, water quality, wetland vegetation geomorphology

Providing important habitat for Australian grayling at critical/vulnerable stages of its life cycle.

hydrology, water quality, wetland vegetation geomorphology

Provision of habitat for diverse vegetation including listed species of flora and rare vegetation communities.

wetland vegetation

The specific components and processes listed in Figure 17and Table 10 (third column) identified as supporting the site’s benefits and services can be summarised as follows:

  • geomorphology (fluvial and coastal)

  • hydrology (freshwater and marine)

  • water quality

  • climate

  • vegetation (intrinsic and as habitat)

  • fish (as food)

  • invertebrates (as food)

The benefits and services listed in Table 9 and Table 10 are all important elements in the ecological character of the site. However, not all are critical to the site’s listing. The critical benefits and services, and the approach to identifying them, are presented below, in section 3.5 of this document.
