A major gain from the issue of mangrove spread has been recognition and acknowledgement that the causative factors, siltation and enrichment, are making due to our land use practices. If we are to preserve our shallow, extensive harbour and its vistas, we need to ensure that only clean water enters it. Removal of mangroves is only toying with the problem.
Forest & Bird spokespersons for many years past, have pointed out the positive contribution – dismissed by Mr Rimmer (Weekend Sun Oct 14) but widely recognised – that this indigenous plant, makes to the harbour and the wider environment.
We have also drawn attention to the negative affects on harbour health (first raised by scientists) that is likely to follow from the large scale removal of mangroves. The mulched tops may have been removed but the half metre or so of dense root material will take years to decay in the anaerobic, saline conditions thus releasing further enrichment and toxicity into harbour waters.
BOP Regional Council has disregarded the science and has undertaken the removal of some large areas of mature mangroves – placating those who demand that their water view must be given priority.
Scientists are part way through a six-year 'Forst” funded investigation into the mangrove spread issue. We await its findings with interest – as should those who have pressed ahead with large scale mangrove removal.
I would point out to Mr Rimmer that 'popularity” is as likely to indicate thoughtlessness or foolishness of decisions, as 'rightness”.
