DEVELOPMENT OF LINE INTERSECT METHOD FOR LOGGING RESIDUE ASSESSMENT OF TEAK
ABSTRACT: Line intersect
method (LIM) emerged as one of the effective and efficient post-harvesting
assessment methods. LIM was being widely used to estimate logging residue of
plantation forest in the temperate zone. This method has not been used in
tropical forest plantations, including teak forests. The study was carried out
to determine the best design of LIM for assessing logging residue in the teak
plantation. The circular and rectangular plot was used in this study. A hundred percent logging residue inventory
was carried out on each plot. Then, one
and combination of two and three line intersects per plot were placed on each
plot. Bias, precision and accuracy criteria were calculated in order to compare
the designs. The study found that estimation of logging residue volume using
LIM was biased and tended to overestimate. LIM design with two lines
combination per plot was the best design for assessing logging residue of the
teak plantation.
