Lincolnshire Wildlife Trust manage this unspoilt stretch of coastline for all to enjoy, Conservation of the natural habitats often involves traditional methods such as livestock grazing.
The sea still covers the marsh on the higher tides. The plants are adapted to cope with saltwater. Sea aster, sea purslane and sea couch-grass thrive but the most striking plant is sea lavender which covers the marsh with a carpet of lilac from late July.
Large numbers of skylark and meadow pipit nest on the saltmarsh. They can be seen performing their song flights during spring and summer.
Foreshore and beach
The beach provides nest sites for little tern and ringed plover. During the breeding season, they are protected in a Shorebird Sanctuary.
Beach ridges provide a roost for thousands of wading birds even on the highest tides.
The youngest sand dunes were formed within the last year and are sparsely covered in grasses such as marram. The oldest are 500 years old and have developed a thick scrub of sea buckthorn, elder, privet and hawthorn.
The open grasslands are rich in wildflowers and insects. This habitat is maintained by grazing sheep and cattle.
Lagoons and ponds
The open water attracts many birds. The lagoons of Tennyson's Sands and Jackson's Marsh were, until recently, farmland. They were created to provide habitat for breeding and migrating waterbirds.
