This dataset contains detailed information from sample plots in Spanderswoud, including raw results from CNS analysis, tree allometric equations, and comprehensive calculations of carbon pools. The data spans the period from February 2023 to June 2023 (collected and analysed) and provides insights into soil and biomass carbon content. The dataset is organized into multiple sheets and files, including plot data, CNS analyser results, tree allometric equations, and carbon pool calculations, along with metadata for clarity.

The study contributes to the development of a standardised, simple and systematic carbon monitoring method by evaluating the validity of the aforementioned techniques. The findings serve as a foundation for future research and support the establishment of a comprehensive carbon monitoring framework for forest ecosystems.
