From the Discovery Centre to Pembrey
In the peace and quiet of Pwll Lagoon Local Nature Reserve many rare plants can be found in this fenland habitat such as southern marsh orchid, common sundew and lesser centaury. In the more wooded areas royal fern and lemon-scented fern grow.
The semi-natural grassland is full of meadow flowers in the summer along with the accompanying buzz of bees and other insects which feed on nectar. Skylark and linnet both nest here along with numerous butterflies such as ringlet, meadow brown, gatekeeper, large skipper, peacock and red admiral.
At Ashpits Pond Local Nature Reserve there are high numbers of breeding birds such as swan, mallard, coot, moorhen, little grebe, great crested grebe and tufted duck. In the summer sand martin are found over the pond hawking for their insect food. Overwintering ducks including gadwall, shoveler, teal, pochard, wigeon and goldeneye.
The large sand dune system at Pembrey Burrows and Saltings Local Nature Reserve is still being formed and contains examples of all the different types of sand dune, from embryo dunes to the large semi-stable yellow dunes. Specialist plants and animals live in the saltmarsh which has formed behind the dunes. It is inundated with saltwater at every high tide and in late summer the purple flowers of common and rock sea lavender cover the ground. The notable insect population of the dunes includes the strandline beetle, the brown-banded carder bee and the tiger beetle. Many bees and wasps use the dry soft conditions found in the sand as nest sites. In the winter also look out for short-eared owl, hen harrier and merlin as they follow smaller birds which come down from the uplands to over winter here.
