In 2002, Camden Haven Community College commissioned a study funded by Coastcare to assess the biodiversity of the Perpendicular Point rocky intertidal zone on Wash House Beach and determine if it is a candidate for consideration as an aquatic reserve. The study found that Perpendicular Point had the second highest number of species of the 10 rocky intertidal shores in the Manning Shelf bioregion. It also had 15 species that were not found on other shores. The report concluded that the zone meets the criteria for nomination as an aquatic reserve. A final determination is dependent on the outcomes of the Manning Shelf Bioregion Assessment Study being carried out by the NSW Marine Parks Authority.
