On Friday 16. 3. Šimon and I visited the Planá sandpit. The purpose of our visit was necessary paperwork, meeting with the sandpit manager, the biodiversity specialist, the national coordinator of QLA and the marketing specialist and mainly claiming our research localities. We picked five same-sized localities, described below, with different geophysical and botanical settings. Then Jakub made corner sticks marked by the orange marking spray so that our sites are easy to spot for quarry workers. Šimon planted his pitfall traps as well (more in his blog which is being prepared).
No. 1: The wet sandbank near large shallow wetland. Sand is average-to-gravel-textured, contains some stones. Sometimes you can find sand-clay parts.
No. 2: Dry wind-transported sand, fine-textured. Locality is next to pine-spruce forest.
No. 3: The typical pine restoration. Sand-to-dirt substrate, average soil hydratation.
No. 4: The abandoned sedimenting basin. Fine-grained, a bit more wet sand.
No. 5: Sand-to-dirt soil, fine-textured. A lot of solitary bee burrows.
In the pictures you can see:
