A slow to medium streams originating in the rainforest of Sekadau, West Kalimantan (Borneo), where Bucephalandra is most common.
- Underwater landscape
The source of the stream is a small waterfall in the hills of Sekadau Hulu. The bottom gravel is brownish. Bucephalandra prefers to grow on land or semi-submersed, although it is also commonly found in water. If water is too hard, the leaves tend to have holes. The water course of the small stream is also filled with fallen leaves, dark stones, driftwood.
- Threats to ecology
Large-scale exploration of Bucephalandra for aquascaping decorations in the country or for export abroad. This plant is endemic only to the island of Kalimantan, so the prices become expensive.
On the other hand this plant requires a very long time to propagate in Nature: it needs a long dry season; according to some reliable sources it even requires El Nino and La Nina storms for some species to propagate.
Besides that, what usually happens is land clearing for oil palm cultivation. There is no law protecting the areas with Bucephalandra in Indonesia.
