What makes Trigg Beach dunes environmentally valuable? What about weeds?  Are these ‘bush dunes’ – sometimes dry and scrappy looking in summer – really of importance?  See the report from Dr Judy Fisher here.

Studies worldwide show a high ‘willingness to pay’ among users of beach and coastline.  Users prefer “unspoiled” beach to “spoiled” beach in study after study.   Prof Paul Hardisty has estimated that any dimunition of quality of Trigg Beach and dunes could result in economic loss to residents and businesses of Scarborough (based on the 2013 boardwalk proposal).  See the report here.

What are parabolic dunes?  And what are parabolic nested dunes?  Dr Vic Semeniuk explains what this dune system is, and where it is at Trigg Beach – and why it is unique and important to preserve!  Re-direct to the Friends of Trigg Bushland page here.
