In summer 2020, Team Echinacea established two plots south of experimental plot 8 for a pilot experiment examining fire effects on Big bluestem (Andropogon gerardii) reproduction. Neither plot was burned during 2020. During spring 2021, we randomly selected the western plot to be burned.
Within each rectangular plot, we selected 30 random points. We then counted the number of flowering Andropogon culms within circular 1m2 subplot centered on each random point (within 56.4 cm). After excluding random points that overlapped with the plot boundary or other random points, we were left with 24 usable random points in the eastern plot and 23 usable random points in the western plot.
Mia harvests Andropogon south of exPt08
- Start year: 2020
- Location: South of exPt08
- Overlaps with: Andropogon fire and flowering in remnants
- Data collected:
- Stakefile for random plot locations: ~Dropbox/geospatialDataBackup2021/stakeFiles2021/stakeAndroPilot2021.csv
- Scanned data sheets: ~Dropbox/burnRems/pilotAndro/androPilot2021
- Samples or specimens collected: Seed heads collected from 2020 and 2021 are currently stored in Jared’s office. These have been dried and will be cleaned / x-rayed to quantify seed set.
- Products: Stay tuned!
