Overton Mere

Overton Mere is a coastal marsh located in Glamorgan, Wales. It is a designated Site of Special Scientific Interest (SSSI) due to its unique and ecologically important characteristics.

The marsh is situated on the southern coast of Glamorgan and covers an area of approximately 100 hectares. It is primarily composed of saltmarshes and saltings, which are low-lying areas of land that are regularly flooded by tidal waters.

The landscape of Overton Mere is characterized by a network of channels and creeks, which are influenced by the ebb and flow of the tides. These tidal waters bring in nutrients and sediments, creating a fertile habitat for a diverse range of plant and animal species.

The saltmarshes of Overton Mere are home to several rare and notable plant species, including sea lavender (Limonium vulgare) and sea aster (Aster tripolium). These plants provide important food and shelter for a variety of invertebrates, which in turn attract a range of bird species such as curlews, redshanks, and lapwings.

In addition to its ecological significance, Overton Mere also holds historical importance. The marsh was once used for grazing livestock and harvesting salt. Remnants of these activities, such as old salt pans and ditches, can still be seen today.

Overall, Overton Mere is a unique coastal marsh in Glamorgan, offering a valuable habitat for numerous plant and animal species, as well as providing a glimpse into the area's historical past.
