In primary and logged-over natural forest , the stand conditions such as stand structure , mortality and ingrowth rates will vary according to the species characteristic. The study objective was to determine mortality and ingrowth /recruitment rates to formulate biometric characteristic variability of dipterocarps forest in logged-over forests based on time series data. The study site was located in Labanan, East Kalimantan Province . Permanent measurement plots within logged -over forest were located to represent three different logging techniques , i.e ., ( a ) reduced impact logging with limit diameter 50 cm (RIL 50), ( b ) RIL 60, ( c ) conventional logging and (d) primary forest as control . Total plot permanent area about 48 ha that measured 2 years periodically along 17 years after logging . Data a nalysis of stands were divided into two major groups, i.e., Dipterocarps and n on Dipterocarps . The mortality rates on logged forest were 2.5-29.3 % ha - 1 2yr - 1 then very close d to primary forest after the 5th year after logging. While the ingrowth rate in logged forest were 1.3 – 21.3% ha - 1 2yr - 1 that have higher value than the primary forest along 17 years . T he mortality and ingrowth rates fluctuation of Dipterocarps species group having different pattern with non Dipterocarps. Keywords : Dipterocarps, logged-over forest, mortality, ingrowth
