I am pondering whether to stick with our current set of bioregions for the rebuild of this website.
Wikipedia says that a bioregion is intermediate between an ecozone and an ecosystem.
Various branches of life and earth science define "bioregion" differently. In the WWF list, New Zealand is one complete bioregion. In another classification, the entire world only has seven bioregions.
Permaculture has its own definition, which definitely has social and cultural overtones instead of being purely nature based. This is significant to our website, as we want to connect communities of interest. While ecologically coastal Taranaki is very similar to coastal Waikato, the human communities are not connected. On the other hand, within the space of 10km between our house and our nearest village, change of altitude means that climate and crop regimes are quite different, but we are definitely part of that community.
Our current regions are based on New Zealand's Regional Councils, whose boundaries are defined by river catchments. This produces a few oddities, such as the Manawatu projecting into what most people regard as Wairarapa, since the river cuts through what would otherwise be considered the main divide. And some regions, such as Northland, are huge. How much connection is there between Kaitaia and Wellsford? Or Rodney and Franklin, separated by the urban mass of Auckland?
On the other hand, dividing the country into too-small regions would mean fewer permaculturalists in each region, and regional filters on the site might be too restrictive.
Does anyone have an alternative list of regions as a starting point?
