Tree and Soil Electrical Resistance in Ghana's Ankasa Forest, 2019

20 trees and one liana were measured for electrical resistance in both wet and dry seasons of 2019. Data includes tree species, diameter at breast height (DBH) ranging from 17.8 to 77.8 cm, and corresponding soil resistivity measurements.

Use Cases

• Analyze seasonal variation in soil resistivity by comparing wet (March) and dry (September) campaign data.
• Model the relationship between tree diameter at breast height (DBH) and its measured resistance to ground.
• Compare electrical resistance properties between the 20 dominant tree species and the single liana (Connarus africanus).

Strengths

• Includes measurements from both wet and dry seasons, capturing seasonal variation.
• Covers a defined DBH range from 17.8 to 77.8 cm for 20 representative trees.
• Data is focused on a specific, well-defined location: the Ankasa Conservation Area in southwestern Ghana.

Limitations

• Small sample size of 20 trees and one liana limits statistical power for broad generalizations.
• Geographic scope is limited to a single forest in Ghana, reducing generalizability to other ecosystems.
• Unknown row and column counts prevent assessment of dataset scale and feature completeness.
