Tree Stem Diameter and Height in Mixed Chilean Forests Under Anthropogenic Disturbance

Field data from twelve stands across four sites in the Andes Cordillera of south-central Chile. The dataset contains measurements of diameter at breast height (DBH) and total tree height (HT) for three tree species, collected using horizontal point sampling. It was funded by the Fondo de Investigación del Bosque Nativo (FIBN) and published by researchers from Technische Universität Dresden.

Use Cases

• Assess the impact of logging, grazing, and seed harvesting on forest structure based on the described disturbance intensity classification.
• Identify optimal tree height prediction models based on diameter at breast height (DBH) measurements.
• Calibrate forest inventory designs using the provided horizontal point sampling methodology.
• Study the structural heterogeneity of mixed Araucaria-Nothofagus forests in south-central Chile.

Strengths

• Includes data from twelve stands classified into four different intensities of anthropogenic disturbance.
• Provides plot-level geographic coordinates (latitude, longitude, and altitude).
• Contains measurements for three specific tree species: Araucaria araucana, Nothofagus pumilio, and Nothofagus dombeyi.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.

Collection Method

Horizontal point sampling measurements of stem diameter and tree height were carried out in 25 to 36 plots per stand.

Geography
