  • The Department of Conservation considers the Conroys Road Inland Saline Wetland Complex to be moderately important site for biological conservation. On a scale from 1 (highest value) to 11 (lowest value) the site was given a rank of 5, on the basis of its geographical extent, relative representativeness (the extent to which the site represents the assumed 1840 condition), diversity and rarity of biota and soils. 8

  • There is the potential threat of invasion by exotic weeds. 8
