Study of recovery process after the Great Fire of tropical rain forest - Second survey in the Kutai National park. East Kalimantan.

东加里曼丹的一大片潮湿的热带森林在1983年的一场森林大火中被烧毁，经过了大约11个月的异常长时间的干燥。库台国家公园位于被烧毁地区的正中心，那里曾经发展出一片壮丽的、成熟的低地丘陵双龙果林，它仍然是整个加里曼丹唯一的这种类型的低地森林保护区。本项目是长期调查项目的二期，旨在研究和记录热带潮湿森林生态系统在森林大火这一异常生态事件后的恢复过程。第一阶段的调查(由h。田川，鹿儿岛大学)于1986年进行。在1992-1993会计年度的野外调查中，监测了火灾后第10年植被演替、土壤昆虫区系、灵长类等哺乳动物区系和重点物种生态的现状。猩猩是该地区重点保护问题的对象，被研究为墙。以下是在8月和12月至2月期间进行的研究活动概述：1)在公园中心的一个小排水系统中设置了四个永久样方，其中两个是没有或轻微受火灾影响的林分。对高度在130厘米以上的树木进行清点，并在每棵树木上进行标记。2)在该流域旁，选取一处条件较好的森林和另一处受干扰较严重的森林，设置200多公顷的宽研究样地，并进行调查样地。研究了哺乳动物区系、灵长类动物分布和密度。3)利用遥测技术对部分食果哺乳动物进行了生态学研究。4)设置样带和样方，评价热带雨林幸存树种林分的种子传播情况。5)在新建道路的边坡上做一组小样方，记录早期连续阶段。

A large area of humid tropical forest of the East Kalimantan was burnt over in a forest fire in 1983, after an extraordinarily long spell of desiccation for about 11 months. In the very heart of the burnt areas lies the Kutai National Park, where once developed a magnificent, well-matured Dipterocarpus forest of lowland hills, which still is the only protected area of lowland forest of this type in the whole Kalimantan. This project is a second phase of long termed survey program, aiming at the study and recording the recovery process of the wet tropical forest ecosystem after the unusual ecological event of big forest fire. The first phase survey (led by Prof.H.Tagawa, Kagoshima University) was undertaken in 1986.In the field survey of 1992-1993 fiscal years, the present condition of the 10th year after the fire were monitored in respect to vegetational succession, soil insect fauna, and Primates and other mammalian fauna and ecology of key species. Orangutans, an object of key conservation issues in the area, was studied as wall. Followings are the outlines of the research activities, done in August and December-February survey periods : 1) Four permanent quadrats were set in a small drainage in the center of the park, two of which were non- or slightly fire affected stands. Inventory of the trees above 130cm tall was made with marking on individual trees. 2) Beside this drainage, a forest of fairly good condition and another heavily disturbed one were selected for setting wide study plots of over 200ha with survey transects. Mammalian fauna, distribution a density of Primates were studied. 3) Ecological studies of some frugivorous mammals were made using telemetry. 4) A transect and a quadrat were set to evaluate seed dispersal from stands of surviving rain forest trees. 5) Made a set of small quadrats on the side-slope of newly constructed road to record the early successive phase.
