Geoff & I have just spent a glorious couple of days, staying in a friends bach at Mangakuri Beach. It’s one of my most favourite places, with long sweeping stretches of polished, wet sand, which reflects the varying shades of the sky. There is hardly ever more than a few people there, if we go out of the busy season, a fact I never take for granted, having grown up on the Kentish coast, where you were lucky to squeeze onto a piece of sand the size of your beach towel, between the crowds also guarding their space.
Ever since those early days, living by the sea I have had a love & fascination for the myriad forms of life that inhabit the rock pools & environs. So, despite it being an official ‘holiday’ for us, I got up early, & with Geoff & Didgit in tow, headed off to explore the rocks at low tide. It’s some years since we have stayed at Mangakuri, & it has weathered severe floods in that time. We were dismayed to find, or rather ‘not find’ many of the creatures we were expecting to be living in the pools & under rocks. We did find quite a few Kina, & young Paua, plus their kin the Shield Shells, there were plenty of those little dark green crabs, with one claw bigger than the other, there were Limpits,Chitons, Cat’s Eyes & Barnacles, & a few Whelks. We saw two large purple starfish, a Sea Centipede & a few worms. What we didn’t see were any Hermit Crabs, usually abundant over most of the pools, no Sea Anemones, no Cushion Stars or their delicate relations the Brittle Stars. Where are the Seaweed Crabs & the little Octopus?
Does anyone know why this beautiful beach & others nearby are so depleted in wildlife? Is it the ongoing effects of the floods, perhaps mud or sand being re-distributed? Is it the various effluents & chemicals getting washed down stream from farms much further away? Whatever it is, it is cause for concern, what was once a richly varied & teeming environment is now much poorer & depleted. I would really appreciate to hear from anyone who can perhaps shed some light on this situation.
I was talking to my Grandson about Hermit Crabs just the other day, & asked him if he’d ever seen one. when he replied that he hadn’t, I had airily said that we would take him to the beach & show him some….I hope we haven’t missed our chance.
