The entrance to Poring Station in the Kinabalu National Park is on the left. In the middle ground is an introduced flowering  African Tulip tree Spathodea campanulata. On the horizon is the Langganan Ridge, a stiff 2.5  hours walk uphill from Poring HQ.

Despite the stiff walk it is well worth the effort , because enroute to the Langganan waterfall you pass through the lowland/montane forest ecotone. There are very significant differences between the birds, mammals and plants (including figs)  found above and below  the lowland/montane ecotone on Borneo’s mountains. The altitude of this transition varies from mountain to mountain dependent on size and location but it starts at around 900m on exposed ridges  eg  the Langanan ridge but may be as high as 1,500m eg the Liwagu river valley at Kinabalu Park HQ. For the explanation see the  illustration at the end of this article. The Hump or mid-elevation effect on tropical mountains”

Ficus fulva Poring 04.JPG
Ficus fulva growing on the roadside just outside Poring Station in the Kinabalu National Park, mixed in with a variety of other plants including a Poikilospermum and a Cyathea Tree Fern. Poring is very rich in fig species  both inside the national park and in the adjacent secondary forest. Ficus fulva is a lowland species of fig replaced  in the Borneo mountains by Ficus endospermifolia and Ficus eumorpha.
