Southwold and Reydon are located entirely within The Suffolk Coast & Heaths Area of Outstanding Natural Beauty. In addition to this special status, which is nationally designated, the northern and southern borders of the parishes are bounded by Sites of Specific Scientific Interest. Much of the land between these statutorily designated sites and the town of Southwold is demarcated as County Wildlife Sites. There are also two nature reserves managed by the Suffolk Wildlife Trust within the parish boundaries, Hen Reed Beds and Reydon Wood.

This special landscape brings responsibilities in its management. The Environment Group monitor both natural and human threats.

Flooding and coastal erosion: The impact of tidal surges, winds and sea level rises challenge the stability of our cliffs and river banks. We seek to obtain the latest information from Waveney District Council and approach the Environment Agency and the Blyth Estuary Group relating to protective measures they plan to take, particularly relating to the north Southwold and south Reydon, and to the banks of the River Blyth.  See also Suffolk Coast Against Retreat.

Sewerage and drainage: Flash floods from rainfall also impact on the sewerage and drainage networks in Southwold. These can affect the quality of our sea water and threaten our Blue Flag award. Increased development in the two communities also has a major impact on the sewerage treatment works. We have met with, and continue to meet, Anglia Water about this continuing problem. Anglia Water have informally acknowledged that there is a problem which they advise us they will address.

Proposed New Quarry, Lime Kiln Farm: The Society, as well as Reydon Parish Council, have asked for this proposal to be rejected. Out of ten sites put forward, it was the only one in an AONB. There are concerns about its impact on wildlife locally and possibly on Hen Reed Beds.

Oil spillage from ship-to-ship transfers: In the past members have lobbied the Shipping Minister and our MP to change national policy. Although transfers are still permitted in Sole Bay, the number of transfers, and the numbers of tankers parked inshore do seem to have declined. The numbers of ships at anchor are regularly monitored.

Reducing the carbon footprint: Members are exploring the possibility with the Waveney Planning Department of encouraging green measures such as double glazing and solar panels in the Conservation Area.

Dog fouling: The Society has provided dog waste bags free for the general public for some years and distributes over 10000 of these a year.
