River temperature is an important control on the health of fish populations. Under climate change it is expected that river temperature will rise with potential consequences for fish populations. Therefore, rivers and fisheries managers require information regarding 1) where the maximum river temperatures occur (where is hottest) and 2) where is most sensitive to climate change (where may change the most). This information can then be used to decide where to plant trees. The layers presented here provide this information for Scotland. River lines in the layers were derived from a Digital Rivers Network licensed from the Centre for Ecology and Hydrology (CEH).
\r\n\r\nThe details of modelling work that produced these layers can be found in the associated peer reviewed manuscript: Jackson et al (2018) \u2018A spatio-temporal statistical model of maximum daily river temperatures to inform the management of Scotland's Atlantic salmon rivers under climate change.\u2019 (see link under \u2018Additional Information\u2019 Tab).
