Sheil, DouglasKartawinata, K.Samsoedin, I.Priyadi, H.Afriastini, J.J.[The lowland forest tree community in Malinau, Kalimantan (Indonesian Borneo): results from a one-hectare plot]The lowland forest tree community in Malinau, Kalimantan (Indonesian Borneo): results from a one-hectare plot

Twenty four permanents sample plots (PSPs), of one ha each have been randomly set up to be a long term monitoring in the hill mixed dipterocarps forest in the Bulungan Research Forest, East Kalimantan. All trees (DBH=20cm) were measured and indentified. In this study area, reduced-impact logging ...


Priyadi, H.Kartawinata, K.Sheil, DouglasSist, P.[Monitoring permanent sample plots (PSPs) after conventional and reduced-impact logging in the Bulungan research forest, East Kalimantan, Indonesia]Monitoring permanent sample plots (PSPs) after conventional and reduced-impact logging in the Bulungan research forest, East Kalimantan, Indonesia

Tree stems contract and expand as stem water is depleted and replaced. Band dendrometer studies suggest that such daily changes are small (<0.2 mm diameter), and they are ignored in most growth measurements. However, several studies using other approaches note larger changes (even >1 cm diameter)...


Sheil, Douglas[Growth assessment in tropical trees: large daily diameter fluctuations and their concealment by dendrometer bands]Growth assessment in tropical trees: large daily diameter fluctuations and their concealment by dendrometer bands

Selective logging applied in tropical forests is based on one universal criterion: a minimum diameter cutting limit for all commercial timber species. Minimum diameter cutting limits in mixed dipterocarp forests of the Malesia region lead to high felling intensities (10–20+ trees per hectare). Su...

Permanent sample plots (PSP) are an important tool in monitoring forest dynamics and change. In Malinau Research Forest, East Kalimantan, 24 PSPs of 1 ha each were established and all trees with dbh = 20 cm were identified and their diameters were measured in 1998 prior to logging operations and ...


Priyadi, H.Sheil, DouglasKartawinata, K.Sist, P.Gunarso, P.Kanninen, M.[Tree growth and forest regeneration under different logging treatments in permanent sample plots of a hill mixed dipterocarps forest, Malinau Research Forest, Malinau, East Kalimantan, Indonesia]Tree growth and forest regeneration under different logging treatments in permanent sample plots of a hill mixed dipterocarps forest, Malinau Research Forest, Malinau, East Kalimantan, Indonesia

Reduced-impact logging (RIL) and conventional techniques (CNV) were compared in a mixed dipterocarp hill forest in East Kalimantan in three blocks of about 100 ha each. Damage was evaluated using pre- and post-harvesting assessments in 24 one-hectare sample plots. RIL techniques nearly halved the...


Sist, P.Sheil, DouglasKartawinata, K.Priyadi, H.[Reduced-impact logging in Indonesian Borneo: some results confirming the need for new silvicultural prescriptions]Reduced-impact logging in Indonesian Borneo: some results confirming the need for new silvicultural prescriptions

Results of a 2-year study on post-fire vegetation dynamics in the unlogged dipterocarp rainforest of Sungai Wain near Balikpapan East Kalimantan, Indonesia are discussed. Results showed that the maintenance of a productive permanent forest estate is likely to be served best by avoiding logging ac...

Meijaard, E.Sheil, DouglasMarshall, A.J.Nasi, Robert[Phylogenetic age is positively correlated with sensitivity to timber harvest in Bornean mammals]Phylogenetic age is positively correlated with sensitivity to timber harvest in Bornean mammals

Reduced-impact logging (RIL) and conventional techniques (CNV) were compared in a mixed dipterocarp hill forest in Malinau, East Kalimantan. Damage was evaluated using pre- and post-harvesting assessments in 24 one-hectare sample plots. RIL techniques nearly halved the number of trees destroyed (...
