Odonata records and environmental data from 20 ponds in the Eddleston Water catchment (Scotland, summer 2023)

<p>This set contains data collected in 2023 in the Eddleston Water catchment for a study on the contribution of flood management ponds to dragonfly (Insecta: Odonata) diversity. Ten ponds created for Natural Flood Management as part of the <a href="https://tweedforum.org/our-work/projects/the-eddleston-water-project/">Eddleston Water Project</a> (funded by the Scottish Government and led by Tweed Forum) and ten reference ponds were surveyed. </p> <p>The following files are available (in both .csv and .txt formats):</p> <p>- "Odonata_AllStages" contains all Odonata data;<br>- "PondEnv" contains information on the surveyed ponds, including basic environmental data (e.g. surface, perimeter) and vegetation variables;<br>- "LandUse" contains the percentage of different land use categories in buffers of 5 and 100 m around the ponds;<br>- "Metadata" describes all variables found in the files mentioned above.</p> <p>Adult Odonata surveys were conducted by following the protocol of the pond biodiversity index "IBEM" (see Indermuehle et al. 2010. <a href="https://doi.org/10.23818/limn.29.08">https://doi.org/10.23818/limn.29.08</a>; and <a href="http://campus.hesge.ch/ibem/odonates.asp">http://campus.hesge.ch/ibem/odonates.asp</a>).</p> <p>Larval Odonata were sampled on a subset of 6 ponds in early June 2023. Qualitative samples were taken with a sweep net (mesh size: 500 µm, 25*18 cm frame size) close to the shore, near the land-water interface. Twenty sweeps of 1 m were conducted in each sampled pond, with the sweeps distributed among the different mesohabitats in proportion to their coverage. The content of the net was then emptied into a white tray and the aquatic macroinvertebrates were directly sorted in the field. Only Odonata larvae were picked and fixated with 70% ethanol, to be identified under the microscope. Larvae were identified to species level where possible, and to genus or family level where this was not possible.</p> <p>Land use and several vegetation variables were collected following the same protocol as in the <a href="https://ponderful.eu/">PONDERFUL</a> project.</p> <p> </p> <p> </p> <p> </p>
