Abstract
Kaluwara (Diospyros
ebenum) commonly called Ceylon ebony is a culturally and economically important
hardwood species in Sri Lanka. Its conservation has been increasingly
challenged by soil degradation, root decay and a long history of selective and
illegal extraction. Traditional forestry methods provide limited subsurface
information and are often invasive, making them unsuitable for rare‑wood
habitats. This study introduces Ground‑Penetrating Radar as a non‑destructive
tool for imaging subsurface conditions in Kaluwara forests. Initial
observations from a set of early GPR survey lines are presented together with a
comparison of existing assessment methods. The preliminary results indicate
that GPR can detect major roots, decayed zones, buried stumps, and soil‑layer
boundaries in dry‑zone soils. As this work represents the first phase of a
broader preservation project further field‑based data collection is needed to
validate and refine these findings.
