The one Lao record is from a marshy valley on the Mekong floodplain. This area is used for dry season rice but floods too deeply to be used in the rainy season, at which time the paddies are rapidly re-occupied by sedges. Much of the marsh was probably once wooded but only scattered trees now remain, as well as degraded forest and bamboo scrub on the surrounding higher ground. Calamus godefroyi was reportedly once very abundant at the site, the local name of which translates as 'rattan lake', but it is now reduced to scattered clumps along banks and ditches in the marsh, with more plants in the surrounding scrub. In 2000 seedlings were common but few adult plants were found. One local man was so concerned by this decline that he has transplanted several clumps to his small-holding; these are thriving and were the source of the recently collected material. (J.

Conservation: Near Threatened (ICUN Redlist 2011) The species has been recorded from three areas on the Mekong River floodplain and associated water bodies; the Vientiane Plain in Lao PDR, and northeastern Thailand and in southern and western Cambodia. However, most of the records are from a relatively small area in Cambodia and it is dependent upon a habitat that is seasonally flooded forest. It is likely to be secure if strong populations occur around the Great Lake in Cambodia, however populations have declined at some known locations and the species is assessed as Near Threatened on the basis of population declines.

Conservation: Near Threatened. (ICUN Redlist 2011) The one Lao record is from a marshy valley on the Mekong floodplain. This area is used for dry season rice but floods too deeply to be used in the rainy season, at which time the paddies are rapidly re-occupied by sedges. Much of the marsh was probably once wooded but only scattered trees now remain, as well as degraded forest and bamboo scrub on the surrounding higher ground. Calamus godefroyi was reportedly once very abundant at the site, the local name of which translates as 'rattan lake', but it is now reduced to scattered clumps along banks and ditches in the marsh, with more plants in the surrounding scrub. In 2000 seedlings were common but few adult plants were found. One local man was so concerned by this decline that he has transplanted several clumps to his small-holding; these are thriving and were the source of the recently collected material. (J.
