SRTMN - Management priority on a scale of 1:9 where 1 is highest priority (i.e. high river temperature and high climate sensitivity) and 9 is lowest (hidden when zoomed in past 1:5,000)

This layer has been developed to combine the outputs from “summer_max_tw_2003” and “summer_climate_change_sensitivity” SRTMN layers into a single layer that can be used to prioritise management where the relative importance of maximum temperature and temperature change are considered to be equal.

This was achieved by (1) dividing the predictions of ‘summer_max_tw_2003’ and ‘summer_climate_change_sensitivity’ into 5 equal categories between the minimum and maximum observed values (2) assigning these categories a value ranging from 1  (the hottest / most sensitive rivers) to 5 (the coolest / least sensitive rivers) (3) sum the rankings (-1) to produce an overall priority ranking (1:9) where rivers ranked as 1 are the highest priority for management (i.e. high river temperature and high climate sensitivity) and 9 the lowest.
