| contents | This dataset stores measurements from two field campaigns in 20 environmental plantings aged 4–35 years old in Australia where stem diameters, crown radii, and heights of individual trees and shrubs were collected, and above- and below-ground woody biomass (AGB, BGB) were calculated. The first measurement was undertaken by The University of Melbourne in collaboration with Land Life Company between March and June 2022 covering 14 sites aged 21-35 years in Victoria, Australia. The purpose of this field campaign was to re-evaluate the biomass carbon stock of sites previously assessed in 2000 by CSIRO within the stem diameter database (SDD; Paul et al. 2020). For each site, to ensure representative coverage, the sampling area was divided into equal-sized sectors and within each sector a random transect of 0.05 ha (100 m length by 5 m width) was laid out based on a restricted random sampling design. Two to five transects were measured per site, depending on either CSIRO last measurement plots or to optimize for the project's resources. In total, the dataset contains 48 transects and 4703 unique tree or shrub measurements. Stem diameters were measured with a diameter tape (>10 cm) or a Stepped diameter Gauge (<10 cm), and height (measured with a laser hypsometer) and crown radius (estimated using a measuring tape) were assessed for only a few representative trees (selected to encompass the full diameter range). The second field campaign was undertaken by Land Life Company between June and July 2023 covering six environmental planting sites aged 4-23 years in Victoria, Australia. The purpose of this campaign was to collect crown data in two directions (perpendicular and parallel to the seeding line). For each site, 14-20 transects of 20 m length were measured (following the seeding line and avoiding gaps or areas of dead plants). In total, the data contains 108 transects and 1341 unique tree and shrub measurements. Crown radius was measured with a tape for each tree or shrub and in addition, stem diameter (measured with a caliper) and height (measured with a laser hypsometer) were also collected. For both datasets, to calculate AGB, stem diameters of multi-stem trees and shrubs were grouped into a single diameter equivalent using the equation of Penman et al. (2003), and then specific plant functional type (PFT) allometric equations (Paul et al. 2015, Paul et al. 2018) were used to derive above and below-ground biomass. |
