Biodiversity Reform

Nandewar - climate

The Nandewar Bioregion is considered mostly to be fairly warm and dry, although average annual temperatures and rainfall vary markedly across the bioregion in relation to elevation (NSW NPWS 2000). The central areas, such as the Nandewar Range and the northern slopes of the Liverpool Range, are generally cooler as they tend to have a higher elevation, whereas the warmer areas correspond to the lowlands around the main river catchment areas.

Average annual rainfall also varies distinctly across the bioregion. It is characterised by frequent rains of high intensity and high run-offs caused by the steep slopes and shallow soils that feature prominently in the bioregion (Morgan and Terrey 1992).

Rainfall generally decreases from east to west, but the differing topography across the bioregion alters this trend somewhat, with areas at higher altitudes, such as Mt Kaputar, receiving significantly more rain annually than lower lying areas in the west (NSW NPWS 2000). The Nandewar Bioregion is subject to summer rainfall (Benson 1999), with the rainfall pattern described as being slightly summer dominant (Morgan and Terrey 1992).
