About PNHA

About PNHA

With urbanisation, there are continuing pressures that threaten the beautiful natural environment of Pittwater. Some impacts are immediate and apparent, others are more gradual and less obvious.

The Pittwater Natural Heritage Association has been formed to act to protect and preserve the Pittwater areas major and most valuable asset - its natural heritage.

PNHA is an incorporated association seeking broad based community membership and support to enable it to have an effective and authoritative voice speaking out for the preservation of Pittwater's natural heritage.

Our Aims

  • To raise public awareness of the conservation value of the natural heritage of the Pittwater area: its landforms, watercourses, soils and local native vegetation and fauna.
  • To raise public awareness of the threats to the long-term sustainability of Pittwater's natural heritage.
  • To foster individual and community responsibility for caring for this natural heritage.
  • To encourage Pittwater Council and the NSW Government to adopt and implement policies and works which will conserve, sustain and enhance the natural heritage of Pittwater.

Our Charter

Pittwater Natural Heritage Association seeks to raise awareness and provide information and advice to our members on issues such as:

Native Tree Canopy

Identification of trees local to your particular area. What to plant to replace dead or dying trees, and how to care for trees. The characteristic form of the native tree canopy is a major contributor to Pittwater's sense of place.

"Bush Friendly" Gardens

Selecting plants for your garden that will live in harmony with nearby bushland and provide habitat for native animals and birds.

Building and Landscaping

Promoting practices which preserve and protect the visual qualities of the landform, preserve soil stability and prevent erosion of steep slopes and siltation of waterways.

Weed Infestation

Information on noxious and environmental weeds, weed identification and methods of control and eradication.

Living with Wildlife

Maintaining habitat and wildlife corridors for our rich and diverse native fauna. Understanding the impacts of introduced birds and animals and uncontrolled domestic pets.

Keeping our Waterways Healthy

Using and enjoying our waterways and estuaries whilst maintaining appropriate water quality and habitat for aquatic creatures. Caring for the streams, wetlands, saltmarsh and mangrove systems that are an integral part of our waterways.

Rock Platforms, Beaches and Dunes

Protecting and preserving the plant and animal communities on rock platforms. Restoration and regeneration of dune systems and maintenance of their stability.

Act to Preserve and Protect!
