Above-ground and soil-seedbank species diversity in the old growth-stage

Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
We used fire-history maps to stratify the landscape into four growth stages: 0-3 years since fire (juvenile); 4–10 years (young); 11–34 years (mature); and >34 years (old). We established 71 sites across the range of growth stages within each region. At each site, we counted all above-ground shrub, sub-shrub, and herbaceous species in six 3 × 3 m quadrats, two each at ridge, mid-slope (midway between ridge and gully) and lower-slope/gully locations. The soil seedbank was sampled by extracting soil cores (6 cm diameter, 5 cm depth) and treating, germinating, and identifying the seeds within.
