The dataset comprises counts of four planktonic diatom taxa collected from Loch Leven from 1968-2007 by staff at the Centre for Ecology & Hydrology and its predecessor bodies, as part of their long-term monitoring programme of the lake. Count units are the density of cells per millilitre of water for four species; Asterionella formosa, Aulacoseira spp, Diatoma spp, Unicellular centric diatoms. Counts are of weekly to monthly frequency and from a single sampling station Full details about this dataset can be found at https://doi.org/10.5285/de5ca6cc-02e9-42bc-a39e-80ec8acbffba

A subset of the Loch Leven long-term monitoring project dataset. This subset contains data collected from Loch Leven between 1985 and 2007 at three sampling sites in the lake. It includes results of chlorophyll, phosphorus, and silicon analyses as well as conductivity and water temperature measurements. The data relate to water samples taken at fortnightly or monthly intervals. Data available in digital form is described here. Additional data currently held as hard copy, will become available once digitised. Full details about this dataset can be found at https://doi.org/10.5285/2969776d-0b59-4435-a746-da50b8fd62a3

The dataset comprises counts of ten waterfowl species collected from Loch Leven from 1968-2007 by staff at Scottish Natural Heritage (SNH) and its predecessor bodies (Nature Conservancy), as part of their long-term monitoring programme of the lake. Counts are for the whole loch and represent an annual peak count based on the monthly counts recorded from September (of the year indicated) through to March (of the following year).
