Recreational intensity decreased during autumn and increased again in March. Boats were very dispersed among different parts of the lake; this was the worst distribution as far as the birds were concerned. The authors concluded that recreation was responsible for significantly limiting the carrying capacity of Llangorse for wintering waterfowl. Prohibiting recreation in certain key areas would probably increase wildfowl numbers and diversity but would require an overall decrease in summer recreation. In winter it would only be necessary to exclude boats from about a quarter of the lake area would to encourage birds. This should not substantially affect the quality of winter recreation. Birdwatching is the most widespread single form of recreation on British inland waters in summer and winter. Some compromise with birdwatchers should be reached at Llangorse Lake which is so important to both recreational and wildlife interests.
