Description
The Acid Watercourses Quality Index (AQUI) for lichens is applicable to upland acid rock watercourses and covers saxicolous species of the following zones: submerged, fluvial mesic and fluvial xeric stream zones (Giavarini, in press). The index excludes montane streams (above 600m) and non-acid watercourses; for lake margins use TNTN (AQUI may be applied to lake margins in future since many of the index species can occur in that habitat but at present no selection threshold has been set). Assessment is based on the number of species and species pairs/groups that have been recorded over a one kilometre stretch. Where entries provide alternative taxa only one can be counted even if two or more members of this species group/pair are present. At least three Verrucaria/Hydropunctaria species must be present to score one (although see exceptions listed under the table), and additional members of these genera do not add further to the total. A site that scores 11 or more should be considered for notification.
