These layers are the outputs of research which developed a national river temperature model for Scotland capable of predicting both daily maximum river temperature and sensitivity to climate change. This layer shows predictions of maximum daily river temperatures for the hottest year in the last 20 years (2003).
These layers are the outputs of research which developed a national river temperature model for Scotland capable of predicting both daily maximum river temperature and sensitivity to climate change. This layer shows predictions of maximum daily river temperatures for the hottest day between July 2015 and June 2016.
These layers are the outputs of research which developed a national river temperature model for Scotland capable of predicting both daily maximum river temperature and sensitivity to climate change. This layer shows predictions of the change in river temperature that would result from a 1°C increase in air temperature.
Salmon Fishery Statistical Region boundaries, used by Scottish Government Marine Scotland for reporting annual statistics obtained from salmon catch returns made by the owners/occupiers/agents of salmon fisheries. (Salmon Fishery Statistical Districts amalgamated into Regions.) Salmon Fishery Statistical Region boundaries were derived by Scottish Government Marine Scotland from Scottish Environment Protection Agency (SEPA) Catchment boundaries, Institute of Hydrology 1:50,000 DTM data and the Salmon Fisheries (Scotland) Act 1868, with some input from District Salmon Fishery Boards.
