There has been a lot of discussion about the removal or otherwise of mangroves. This fact sheet form the then Auckland Regional Council is helpful http://www.arc.govt.nz/albany/fms/main/Documents/Plans/Regional%20Policy%20and%20Plans/Operative%20ARP%20Coastal/Change%204/Mangrove%20seedling%20removal%20factsheet%20Oct%202010.pdf

Is F&B into this?? http://www.youtube.com/watch?v=Hxf8sGLaw6w&feature=feedu
We are neither for or against, we generally try to weigh up a lot of factors including the effect of roosting birds, effect on marine biodiversity etc etc. Everything is done on a case by case basis.
In the Hokianga, the mangroves are five metres high and they provide great habitat for birds such as grey warblers and tui.
In Whangamata, the mangroves don't provide great habitat and they're taking over important eel-grass beds.
In this case, the mangroves have cropped up because of poor land management.
Forest was cleared on the hills and replaced with pines in an area that was too steep, so that created sedimentation and a prime habitat for mangroves!
Hope this answers your question kukupa
This discussion might help answer, too http://blog.forestandbird.org.nz/mud-slinging/#comments
Just by chance, we had a clean-up event at Whau River in West Auckland yesterday, and as it happened a debate started when local residents were saying about the dramatic increase in mangroves in parts of this estuarine waterway.
The piccie below shows a bit about the area and you can see the mangroves which apparently weren't there or in far fewer numbers only a couple of years ago.
The area we were at is literally MILES away from the Waitakere Ranges, but the theory is that when these ranges were deforested years ago, we are still seeing the sediment from the catchment being brought down to the coast, and trapping of it is giving mangroves a place to move into. I imagine the warmer weather in the past couple of years would’ve possibly exascerbated the mangrove settlement?
You can post the photos onto the thread. Unfortunately only people with a facebook account will be able to view those piccies!
