Vegetation in reserves is generally in a reasonable condition. Remnant vegetation on private proporty is generally in poorer condition.

A Green Corridor is a continuous length of vegetation linking isolated patches of remnant native bushland and trees.In the upper Parramatta River catchment many areas of native bushland remain along creek corridors. It is important to protect green corridors because they:

• protect local plants and animals and threatened communities;
• provide habitat for native fauna;
• provide protection of riparian areas (those on the margins of creeks);
• improve opportunities for recreational use of these areas by the community;
• improve and protect the scenic qualities of local creeks and rivers.

What are the different types of Green Corridor?

Three types of green corridors have been identified based on the geological and ecological landscape in which they occur. They are: -

1. Cumberland Plains Corridors

• Blacktown Creek
• Grantham Creek
• Greystanes Creek
• Coopers Creek
• Finlaysons Creek
• Pendle Hill Creek
• Upper Parramatta River

2. Sandstone/Shale Transition Zone Corridors

• Toongabbie Creek
• Quarry Branch Creek

3. Hornsby Plateau Corridors

• Darling Mills
• Hunts Creek
