“…The invasion of non-forest species or early-successional species may obscure our view on the reduction of true forest species with disturbance. For instance, species of terrestrial pteridophytes vary in their requirements for shade, and groups of 'forest species' and 'nonforest species' of terrestrial pteridophytes can be distinguished based on those requirements (Beukema and Van Noordwijk 2004). Epiphytes on the other hand are mostly related to old secondary forest and primary forest, as they depend on the development of tree trunks and branches for their habitat.…”

Plant and bird diversity in the Indonesian jungle rubber agroforestry system was compared to that in primary forest and rubber plantations by integrating new and existing data from a lowland rain forest area in Sumatra. Jungle rubber gardens are low-input rubber (Hevea brasiliensis) agroforests that structurally resemble secondary forest and in which wild species are tolerated by the farmer. As primary forests have almost completely disappeared from the lowlands of the Sumatra peneplain, our aim was to assess the contribution of jungle rubber as a land use type to the conservation of plant and bird species, especially those that are associated with the forest interior of primary and old secondary forest. Speciesaccumulation curves were compiled for terrestrial and epiphytic pteridophytes, trees and birds, and for subsets of 'forest species' of terrestrial pteridophytes and birds. Comparing jungle rubber and primary forest, groups differed in relative species richness patterns. Species richness in jungle rubber was slightly higher (terrestrial pteridophytes), similar (birds) or lower (epiphytic pteridophytes, trees, vascular plants as a whole) than in primary forest. For subsets of 'forest species' of terrestrial pteridophytes and birds, species richness in jungle rubber was lower than in primary forest. For all groups, species richness in jungle rubber was generally higher than in rubber plantations. Although species conservation in jungle rubber is limited by management practices and by a slash-and-burn cycle for replanting of about 40 years, this forest-like land use does support species diversity in an impoverished landscape increasingly dominated by monoculture plantations.

Cibotium barometz (L.) J.Sm. (Cibotiaceae) is an important export commodity for both traditional and modern medicine. Populations of this species in several countries have decreased rapidly due to the uncontrolled collection of the rhizome parts for medicinal purposes. Since 1976, this species has been included in Appendix II of the Convention on International Trade in Endangered Species (CITES). This means that no export is allowed without a prior permit issued by the CITES committee. In order to utilize an endangered species sustainably, the global NDF (Non-Detriments Finding) system is applied for determining annual quotas. Therefore, monitoring and updating the inventory of C. barometz in its natural habitat should be carried out annually. A population study of C. barometz carried out in 2011 in Riau Province, Sumatra, is reported here. The aims of the study were: 1) to inventory C. barometz and determine its variation in Riau Province, Sumatra, 2) to study the distribution and ecology of C. barometz, and 3) to assess the population size of this species by using random search methodology incorporating belt line transects. Two variants of C. barometz are recognized; they are the golden yellow and golden brown variants. C. barometz is distributed in eight locations of Kampar District of Riau Province, in the secondary forest and rubber agroforest between 80 m and 600 m above sea level (asl). This species grows well in open to partially opened areas of secondary forest and rubber plantation in hills with a range of slope between 30° and 90°, with a relatively high humidity, 60 -90%, in acid to nearly neutral soil, with a range of soil fertility from very poor to very humus rich soil. The average population density determined in our study was 20 plants per 100 square meter. The highest population size was in the secondary forest of Bukit Kuda Beban at 590 -600 m asl., viz. 9405 plants with a population density of 47 plants per 100 square meter.
