Coastal Saltmarsh Monitoring
This project was commissioned by the Countryside Council for Wales (CCW) primarily to cover the condition monitoring of the Annex I saltmarsh habitats across four Welsh Special Areas of Conservation (SAC) (see Annex 1 for maps). The two habitats concerned are: Atlantic salt meadows (referred to as ASM) - Annexe I code 1330, and Salicornia and other annuals colonising mud (referred to as 'Salicornia') - Annexe I code 1310. The areas of focus were: Glannau Mon Cors Heli SAC, Pen Llyn a'r Sarnau SAC, Pembrokeshire Marine SAC, and, Carmarthen Bay and Estuaries SAC.
Glannau Mon Cors Heli SAC, Pen Llyn a'r Sarnau SAC, Pembrokeshire Marine SAC, Carmarthen Bay and Estuaries SAC.
The purpose of this data capture was to assess condition status of Annex 1 habitats.
Confidence in this data is High and field work carried out by Central Environment Surveys (CES) under contract to the former Countryside Council for Wales.
Within each Special Areas of Conservation (SAC) a series of transects were established, totalling 39 across the four SACs. At each point along the transect presence and absence of a suite of species was used to determine the saltmarsh zone present. Additional information was recorded at each point such as presence of vehicle tracks, bare patches due to poaching damage, anoxic algal mats, Spartina anglica, grazing indicators, pollution damage, turf cutting and rare species. Targets were set for what constituted good condition on a point, transect and SAC level. For some sites estuary specific targets were also set.
Surveys were conducted as follows:
- Glannau Mon 28-30 Sept 2006
- Pen Llyn a'r Sarnau 1-6 Oct 2006
- Pembrokeshire Marine 7-11 Oct 2006
- Carmarthen Bay and Estuaries 17-20 Oct 2006
