Recent and historical records of red and grey squirrels submitted to the Scottish Squirrel Database, an ongoing system of monitoring squirrels throughout Scotland currently administered by the Scottish Wildlife Trust. The dataset brings together historical records from the Scottish Squirrel Survey, data generated by the Saving Scotland's Red Squirrels project (including web recording forms), and recent and historical records submitted to the database by squirrel groups, local record centres and other organisations. The dataset is updated annually.
