|Redhead Beach, NSW|
|The seaweeds collected from the tideline|
|What I found on 'pristine' Redhead Beach|
|A full bag of plastics and rubber picked up from the shore|
Apart from dismay at how nobody else seemed to care about picking up rubbish, it also started me thinking about how items end up on shore and applying this thought to seaweed, shells and other natural objects. If plastics can be washed up miles from where they enter the sea, and we know they do not originate from the ocean, then do the seaweeds I find on the beach originate from that area, or have they too been in circulation from another beach until they are washed up? When I collect my seaweed I press it and label it with the date and location, as did Charles Morrison back in the 1800's. These details enable us to see what species were growing at a particular place in time. Or do they? If you are not dredging the seaweed from a location, then how reliable is it to posit that what you find not the shore comes from that particular beach/body of water?? This and other things to mull over whilst I collect seaweed......and rubbish.
