Biodiversity is the full range of life on earth, including plants, animals, fungi, micro-organisms and also the environment in which they live.
It's importance is in supporting the critical ecosystem processes that maintain and regulate everything from the atmosphere and climate through to disposal of wastes.
New Zealand is a biodiversity "hotspot". Many of our native species are endemic and do not occur naturally anywhere else on earth.
Development such as agriculture, forestry, fishing, aquaculture, and tourism all depend on sustainably managed natural resources and all rely on biodiversity.
Our district's natural environment
The natural environment plays an important role in defining the character of the Whangarei district and contributes to our unique sense of place. It contains many varied landscapes with a wide range of habitats.
About 9% of the district is formally protected either as public conservation land, Council reserves, QEII covenants, Nga Whenua Rahui kawenata or as Fish and Game wetlands.
Māori are kaitiaki for the biodiversity of tribal areas and holders of traditional tribal knowledge. They are also developing their own iwi management plans to address natural resource issues within their rohe, including biodiversity.
Threats to biodiversity
The well-being of our natural environment, nationally and regionally, is under pressure from a range of threats including:
habitat loss and fragmentation through deforestation, drainage and reclamation
introduced predators such as mustelids, rats and feral cats
invasive plant and animal pests including aquatic species
over-exploitation from commercial fishing, illegal and unsustainable harvesting
pollution through sewage, inappropriate use of pesticides and sedimentation
climate changes in temperature, rainfall and sea level rise
spread of diseases such as chytridiomycosis in frogs and the Kauri dieback disease
natural catastrophic disturbance eg fire, drought and floods
small population sizes and restricted distribution
human activity through subdivisions and urban expansion, land use change and genetic modification
lack of general knowedge about sustainable management.
Of the total number of species found in the Whangarei district, there are 205 at risk or threatened - 125 are animals and 80 are plants.
Some habitats, such as wetlands, dune lands and lowland/coastal forests are acutely threatened and in need of protection and/or restoration. Less than 4% of Whangarei's original wetland remain.
We contribute to the QEII National Trust to set up new open space covenents in the district and also work with other agencies and community groups to enhance biodiversity on public reserves.

You can help to protect and restore the biodiversity in our district by:
increasing the natural habitat by growing native plants that naturally occur in your area
growing plants from seed gathered from local remnants
creating habitats using features such as bird baths, hollow logs, ponds, rocks, and nesting boxes
removing environmental weeds and controlling pests
composting to recycle organic matter like kitchen scraps and lawn clippings
keeping stock out of water courses to improve water quality in our streams and harbour
being a responsible pet owner by keeping pets inside or contained at night
walking your dog on a lead, particularly in kiwi areas
joining or supporting a local landcare, coast care or weedbuster group
legally protecting your special places for future generations.
