Nandewar - conservation status analysis

This page shows the conservation status of the bioregion, based on protection of landscapes within formal conservation management mechanisms.

The numbered landscapes referred to in the text are described briefly in the table at the bottom of the page. These landscapes were identified in the State Conservation Monitoring Project. In this project, a total of 1167 landscapes were described, combining three layers: ruggedness, geology and subregions.

Landscape-scale conservation

There are 70 landscapes in the NSW portion of the Nandewar Bioregion (NPWS in prep).

Of the 70 landscapes, just over half (36) are represented in the conservation mechanisms surveyed. Of these, 23 are represented in one mechanism only, and where this occurs the proportion of landscapes conserved is generally small. Six landscapes (324, 317, 339, 336, 344, 386) do achieve greater than 20 per cent representation and all lie only in national parks or nature reserves.

National parks and nature reserves

Twenty-nine of the 70 landscapes lie in national parks and nature reserves. The ruggedness and geology of these landscapes varies. The subregion of origin of the landscapes are the Peel, Kaputar and Nandewar, Northern Complex subregions. The 6 landscapes with more than 20 per cent of their NSW bioregional area in parks and reserves are:

  • Landscape 324 with 1,867.71 hectares or 23.06 per cent of its bioregional area;
  • Landscape 317 with 15,885.44 hectares or 51.74 per cent of its bioregional area;
  • Landscape 339 with 7,262.84 hectares or 59.05 per cent of its bioregional area;
  • Landscape 336 with 3,281.82 hectares or 82.05 per cent of its bioregional area;
  • Landscape 344 with 4,896.64 hectares or 84.42 per cent of its bioregional area; and
  • Landscape 386 with 100.00 hectares or 100.00 per cent of its bioregional area.

Wildlife refuges

Eleven landscapes (137, 109, 126, 168, 101, 173, 110, 102, 154, 106 and 111) are represented in wildlife refuges, although the greatest proportion of a landscape represented by this program is 1.93 per cent. Four of these landscapes (109, 126,173 and 101) are not represented in the national park and nature reserves of the bioregion.

  • Landscape 137 with 0.93 hectares or <0.01 per cent of its bioregional area;
  • Landscape 109 with 0.96 hectares or 0.01 per cent of its bioregional area;
  • Landscape 126 with 0.98 hectares or 0.06 per centof its bioregional area;
  • Landscape 168 with 3.32 hectares or 0.03 per centof its bioregional area;
  • Landscape 101 with 4.26 hectares or 0.03 per centof its bioregional area;
  • Landscape 173 with 27.92 hectares or 0.20 per centof its bioregional area;
  • Landscape 110 with 137.78 hectares or 1.51 per cent of its bioregional area;
  • Landscape 102 with 208.28 hectares or 0.16 per centof its bioregional area;
  • Landscape 154 with 392.08 hectares or 0.22 per cent of its bioregional area;
  • Landscape 106 with 427.48 hectares or 0.50 per centof its bioregional area; and
  • Landscape 111 with 686.49 hectares or 1.93 per cent of its bioregional area.

State recreation area

Only one landscape, Landscape 110, with 72.5 hectares or 80 per cent of the area of the landscape, occurs in state recreation areas. A larger area of this landscape is represented in national parks and nature reserves and in the wildlife refuge program.

Flora reserves

A relatively small proportion of 2 landscapes is represented in flora reserves: 10.65 hectares or less than 0.01 per cent of landscape 232 and 38.12 hectares or 0.02 per cent of landscape 239. Small areas of Landscape 232 are also represented in the conservation zone of property agreements and in national parks and nature reserves. Landscape 239 is also represented in national parks and nature reserves.

Property agreements

Five landscapes (231, 229, 233, 232 and 235) are represented in property agreements in the NSW portion of the bioregion. These are:

  • Landscape 231 with 3.48 hectares or <0.01 per cent of its bioregional area;
  • Landscape 229 with 7.41 hectares or 0.01 per cent of its bioregional area;
  • Landscape 233 with 13.47 hectares or 0.02 per cent of its bioregional area;
  • Landscape 232 with 16.89 hectares or 0.01 per cent of its bioregional area; and
  • Landscape 235 with 95.81 hectares or 0.12 per cent of its bioregional area.

Two of these (231 and 233) are not represented in the system of national parks and nature reserves. The proportion of each represented is less than 0.12 per cent of the respective landscapes.

Conservation and clearing

A very high proportion, about two-thirds (1,371,100.00 hectares or 66.33 per cent), of the Nandewar Bioregion has been cleared of its native vegetation canopy and a large proportion of the landscapes (61 of the 70) have experienced this form of clearing activity.

Five landscapes ranging in area from 100 hectares to 400 hectares have been totally cleared while a further 19 have experienced extreme levels of clearing of greater than 70 per cent of their area. A further 12 landscapes are highly cleared, with greater than 50 per cent of their area cleared, and 14 have greater than 30 per cent of their native canopy cleared.

Of those high to extremely cleared landscapes, eleven (261, 102, 137, 232, 168, 229, 153,154, 198, 316 and 358) are represented in the system of national parks and nature reserves. Eight (109, 102, 126, 137, 168, 173, 154 and 101) are included in wildlife refuges and 4 (232, 229, 233 and 231) are included in property agreements.

All landscapes lacking at least minimal representation in high-security conservation tenures (national parks, nature reserves and flora reserves, VCAs and property agreements, if perpetual) are a priority for conservation. The remaining vegetated areas of highly cleared landscapes are a priority for conservation action, including restoration, particularly if further clearing activity within the unprotected areas of these landscapes is likely.
