Distances walked by beach users and protecting shorebird habitat zones from disturbance

Human population growth along Australias coast is increasing development and recreation pressures on beaches and shorebirds. This study observed human recreation on 18 beaches on the far north coast of New South Wales in February and March 2019. The far north coast supports the largest numbers of beach-resident Australian Pied Oystercatchers Haematopus longirostris in the State. The most frequent activities observed were walking (29%), dog walking (21%) and swimming (16%). Walkers covered greater distances compared to other beach users. For beach walkers and dog walkers combined, the mean along shore distance walked from an access point was 809 m and the 95th percentile was 1990 m. Noting that human recreation disturbance is a major conservation threat to beach nesting birds and that pro-environmental behaviour is uncommon among beach users, large separation distances between beach access points and shorebird habitat zones are recommended to reduce human intrusions into those zones. This spatial zoning and passive human exclusion strategy can be applied to long and less-developed beaches.
