Pollarded Beech Tree Census in Otari Village, Nagano, Japan

60.3 KB of individual tree census data from a forest dominated by pollarded beech (Fagus crenata) in Otari Village, Nagano Prefecture, central Japan. The data were collected by Hideyuki Ida for a field study investigating the structure and historical utilization of a traditional pollarded beech stand in a snowy mountain region. The dataset provides information on tree morphology, stand structure, and the legacy of traditional forest resource use.

Use Cases

• Analyzing stand structure and spatial distribution based on East and North coordinate columns.
• Studying the morphological effects of pollarding based on stem type, sprout level, and sprout diameter.
• Reconstructing historical forest management practices based on remarks and sprout tier data.
• Modeling tree growth patterns in heavy-snow regions based on girth at breast height and stem height measurements.

Strengths

• Includes detailed morphological measurements for individual stems, such as girth at breast height (GBH), stem height, and sprout diameter.
• Contains spatial coordinates for tree positions within a defined 40x40 meter census plot.
• Documents a specific traditional forest management practice (pollarding) with historical context until around 1950.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Data is limited to a single 40x40 meter plot in one village, representing a very localized case study.
• The dataset is small (60.3 KB), indicating limited scope and sample size.
