Summer 2020 data from five sites in northwest Patagonia, Argentina, measures grassland productivity metrics and three abundance measures for invasive Pinus contorta. The dataset includes total green biomass, palatable green biomass, sheep stocking rate, tree density, basal area, and canopy cover.
Use Cases
- Model the relationship between Pinus contorta basal area or canopy cover and total green biomass to quantify invasive species impact on grassland productivity.
- Calculate sustainable sheep stocking rate based on palatable green biomass measurements to inform grazing management.
- Analyze correlations between the three Pinus contorta abundance metrics—density, basal area, and canopy cover—across the five study sites.
Strengths
- Includes three distinct field-measured metrics for invasive species abundance: tree density, basal area, and canopy cover.
- Data collected from five different sites across a gradient of Pinus contorta invasion.
- Productivity metrics are specific, including total annual biomass and biomass palatable to sheep.
Limitations
- Single temporal snapshot from summer 2020, limiting analysis of seasonal or interannual trends.
- Geographic scope is limited to five sites in northwest Patagonia, Argentina.
- Sample size and row count are unknown, which may constrain statistical power for certain analyses.
