Description: <DIV STYLE="text-align:Left;"><DIV><P><SPAN>This layer describes conservation rankings for New Zealand's lakes calculated both within national and regional contexts, and taking account of human pressures. Estimates of human pressures were estimated from a range of data including descriptions of the catchment cover of both native vegetation and impervious surfaces, the modelled nitrogen load, the presence of introduced plant and fish species, and the effects of artificial impoundments - see deWinton et al. (2009) for details. The likely impacts of each of these factors on the ecological integrity of lakes was estimated using expert judgement, and these impact scores were combined using two different approaches. Because of the lack of consistent information about the presence of introduced plant species, values for each approach were calculated both including and exclusing this factor. Conservation rankings were calculated using pressure estimates calculated using equation one, with macrophyte data excluded. These estimates of pressure were then combined with data describing classification membership for each lake at the Natural.4 level of detail (67 groups), and analysed using Zonation (see Leathwick et al. 2010) to calculate rankings of conservation importance. This approach ranks all sites in order of decreasing importance according to their ability to contribute to a representative set of protected sites. For example, protecting the top 10% of sites would achieve the maximum possible degree of representation across environmental groups, given that degree of protection. Rankings are calculated both for all NZ lakes, and for lakes within each WONI biogeographic unit. A second set of rankings were calculated in which lakes having 80% or more of their area protected were held back until all other lakes had been removed - this indicates both the relative value of protected lakes, and those lakes currently lacking protection that would best complement those already protected.
