Human Impact

  • Extent of Fringing Vegetation

    Presence / Absence Survey

Lateral Extent of Fringing Vegetation - Within a 100m buffer from the edge of the saltmarsh towards upland, measured along the perimeter of the saltmarsh


Width of Fringing Vegetation - Adjacent to the saltmarshes within a 100m buffer from the edge of the saltmarsh towards upland, measured along the perimeter of the saltmarsh


  • Condition of Fringing Vegetation

    Adjacent to Saltmarsh Site

Native Vegetation Composition - Relative to introduced species within a 100m buffer (as above)


  • Livestock Disturbance

    i.e. Animals raised in agricultural setting

Grazing WITHIN the saltmarsh (apparent vegetation removal, soil disturbance, livestock tracks, droppings or other forms of disturbance)


Grazing ADJACENT to the saltmarsh (apparent vegetation removal, soil disturbance, livestock tracks, droppings or other forms of disturbance)


  • Feral Animal Disturbance

    (Vegetation removal, soil disturbance, tracks, droppings)

Impacts WITHIN the saltmarsh (apparent vegetation removal, soil disturbance, livestock tracks, droppings, or other forms of disturbance)


Impacts ADJACENT to the saltmarsh (apparent vegetation removal, soil disturbance, livestock tracks, droppings, or other forms of disturbance)


  • Major Development (Land-Use Conversion)

    Major developments are a significant concern to conservation

Any major development WITHIN/ON the saltmarsh that has replaced the original habitat (e.g. houses, buildings, playing fields, tip sites, farms constructed over saltmarshes)

Any major development ADJACENT to the saltmarsh that has replaced the original non-saltmarsh habitat (e.g. houses, buildings, playing fields, tip sites, farms constructed over non-saltmarsh habitats such as woodland, grassland, freshwater wetlands etc.)

  • Other Distrubance

    Inappropriate Habitat Disturbance Features

Rubbish debris (e.g. plastics, glass, metal)

Dumping of rubbish (e.g. old tyres, building waste, garden waste)

Roads / walking tracks within

Unmanaged tracks from use of off-road vehicles

Presence / extent of drainage channels, levees, ditches within the saltmarsh

Other - please specify in comments below

  • Algal Blooms

    Nutrient enrishment / eutrophication

'Rotten spots' on the saltmarsh - Nuisance algal blooms on the saltmarsh platform (on plants or pools in the saltmarsh)

'Rotten spots' in tidal areas - Nuisance algal blooms in tidal channels or tidal flatsboth within and adjacent the saltmarsh
