Geography comments: "one of the peat swamp forest strips dividing the sago plantation of the PT. National Sago Prima (PT NSP)... The plantation is located at Selat Panjang, the Tebing Tinggi District, Kepulauan Meranti Regency, Riau Province... The first quadrat was established at the coordinate of 00°48'53.5" N and 102° 53'44.3" E with the mean altitude of 16 m, with the altitude of 0-50 m asl"
Climate and habitat
Habitat: tropical/subtropical wetland
Substrate: ground surface
Disturbance: selective logging
MAT: 27.6
MAP: 1966.0
Habitat comments: "peat swamp forest that forms a corridor of 300 m wide extending for 40 km from south-east to north-west along the northern border of PT NSP... selectively logged during the periods of 1974-1994 and 1995-􏲹2003... It was further converted into the Industrial Timber Estate and then into the sago industrial forest plantation. The area was also illegally logged by local community in 2000-2005" but the site itself is clearly not a plantation
