DIAGRAMMATIC STRATEGY
AQUACULTURE
dunescape containing existing wet and dry slacks existing drainage channels proposed combination water channels (wet)
semi wet combination channels wetland development
proposed artificial wet slacks
existing pasture and vegetable farming proposed saline agriculure low tolerance oil seed crops
AGRICULTURE
low - medium tolerance semi permanent forage crop trials
semi permanent saline agriculture - medium tolerance oil seed crops low tolerance oil seed crops reed harvesting
wet combination channels increasing wetland development containing plugs to control saline and fresh water combintaions
halophytes in salt marsh harvested for biomass low tolerance oil seed crops medium tolerance forage crops
MAD WHARF MANAGEMENT STRATEGY IMPLEMENTATION STAGE at implementation stage, constructed environments are positioned to respond to the sudden change in on site water volumes created by reducing the gip of the drainage system on the landscape. they are effectively biocentric solutions to water storage problems. consequential environments are biocentric responses to the intervention which are encouraged through management to develop and provide opportunities for more diverse forms of production and biodiversity.

saline channel
dunescape
marsh boardwalk
embryonic to fixed dunes remain wild landscapes with very low density sheep grazing to prevent over stabilising of dunes
salt waterscape
wet slacks hold large volumes of sea water which is collected when tides are high. more intensive sheep grazing occurs in the backlands as it is less damaging to the dune system and controls dominant scrub invasion.
fibre optic bundles
leisurescape
marsh canopy walks which divert visitors away from the existing over used tourist footpath allow people to experience the unique fibre optic salt marsh environment whilst retaining the landscape’s fragility.

fresh waterscape
a more conventional agricultural landscape provides space for economically viable production of salt tolerant crops such as salicornia, sea kale or sea aster. these are distributed locally and regionally using the new water channels which link up to the river alt.
lower fresh water marsh land is able to withstand periodic immersion through succession of highly absorbant phragmites and salix species. upper wetland areas experience more exposure and can be grazed.
