Limestone grassland, heath and quarries.
0.5km south of the village of Overton. Access can be
gained by way of the kissing gate adjacent to the first field gate on
the left on the track leading out of Overton Village to the west, or by
way of the coastal public footpath from Port Eynon Point.
The reserve is named after the bay over which it looks.
Overton Mere has almost the full range of South Gower Coast habitats ranging
from Hawthorn and Blackthorn scrub, through mixed gorse and heath, open
limestone scree, to improved and unimproved limestone grassland.
The areas of improved grasslandare to be found on the plateau area closest
to the sea shore which is a fossil raised beach dating back to the last
ice age. Lime-loving flowers such as Common Rock-rose, Milkwort, Eyebright,
and Wild Thyme flourish, while birds such as linnet and Meadow Pipit search
the grassland and scrub for food. Oystercatcher and other shore birds
can be seen in the mere at low tide.
