Vegetation Sampling

Vegetation sampling is the identification and quantification of plant species and communities. Vegetation sampling is a tool used in environmental assessments and can inform a myriad of assessment goals including biomass availability, water quality concerns, management benchmarks, and determining the introduction and establishment of invasive species. Sampling can be conducted via destructive or non-destructive methods. Learn more about vegetation sampling from the links and documents listed below.
