Diversity of indigenous birds chart 2015

Availability:This data is collected by RIMU as part of the Terrestrial Biodiversity Monitoring Programme (TBMP); which includes a network of over 300 forest plots located in a grid pattern across the Auckland region.
Note:This indicator is presented by Ecological Neighbourhood. Species diversity and pressures from development vary widely across the region, and using regional averages might disguise important changes.
Relevance:Absolute diversity is a widely used measure of the quality of habitat, with more diverse ecosystems generally being seen as ‘better’ than less diverse ones. This is because more diverse communities have been shown to have higher and more temporally stable ecosystem functioning, and consistently higher productivity, than less diverse ones (Allan et al. 2011).
Forests with a higher diversity of native bird species will also benefit from increased seed pollination and dispersal for a wider range and larger amount of native plants, which subsequently improves the habitat for a wide range of organisms (e.g. invertebrates, soil biota) lower in the food chain.
