Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Past Methods (No longer in use)

  • Seedling metrics
    Started: 2013-05-15
    Ended: 2013-08-31

    Seedlings- frequencies and densities of woody stems in 1m2 subplots were calculated

  • Seedling sampling
    Started: 2013-05-15
    Ended: 2013-08-31

    A 1x1m quadrat was placed at each subplot and all tree seedlings within were counted below 50 cm tall and below 200 cm tall (excluding first year germinants).
