Birch Sap Extraction and Tree Physiology Data from Northwestern Spain

Betula celtiberica sap extraction data includes water potential and chlorophyll fluorescence measurements to assess short-term physiological impacts. The dataset, 220.8 KB in size, also contains biochemical composition analysis of the sap for biocompound characterization. Authored by Estrella Alfaro-Saiz and last updated in March 2026, it originates from the Reserva de la Biosfera de los Valles de Omaña y Luna.

Use Cases

• Assessing short-term physiological impacts of sap extraction based on water potential and chlorophyll fluorescence measurements.
• Characterizing biocompounds in birch sap for potential food and cosmetic applications.
• Evaluating sustainable sap collection practices for small-scale production in specific forest ecosystems.

Strengths

• Data includes physiological measurements (water potential, chlorophyll fluorescence) taken 1 month post-extraction.
• Biochemical composition analysis supports evaluation of sap for commercial uses.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The study scope is limited to short-term (1-month) effects; long-term impacts are not assessed.
• Data is geographically specific to the Betula celtiberica forests of north-western Spain.
