Kinabalu National Park, Sabah, Malaysia

“No, I’m not climbing to the peak” I tell our excellent guide

While in Kinabalu National Park,  (Sabah, Malaysian Borneo) I’m not sure if our guide said “look up there” or I just noticed and photographed the pretty canopy outline then later heard about ‘canopy shyness’. I just know the narrow yet clear gaps between the tree crowns is attractive.

Canopy, or crown, shyness is, I now know after research, is a phenomenon in which some tree species make sure they do not touch each other: forming canopies with channel-like gaps. It’s most common among the same species.

This growth has been discussed in scientific literature since the 1920s and many hypotheses have been put forward as to crown shyness being an adaptive behaviour. Research suggests that it maybe stops the spread of leaf-eating insect larvae, and, or, also possible physical explanations such as light shading sensing by adjacent plants.

A Malaysian scholar, Francis S.P. Ng, studied (1977) the Malay camphor tree and suggested that the growing tips were sensitive to light levels so stopped growing when near other foliage due to the induced shade.

However, apparently, the most likely theory is that the trees simply do not want to hurt themselves in windy areas!

I wonder – I just know the gaps between the trees provided me with a couple of  striking photos.

Is this a Malay Camphor?
