Being the highest point on this open grassland means lots of wind!
We finally started work on Project Merbok a few months back. One of the most important things we started with was to create windbreaks. You might ask: what’s wrong with enjoying a breeze in our warm humid climate? While a gentle wind helps with air circulation, too much of it causes many problems.
- Soil erosion: Organic matter (dead leaves, dried twigs) are very light and will get blown away easily. That leaves the soil exposed and also takes away the nutrition from rotting matter that the soil needs.
- Dryness: Wind removes moisture from the soil and plants. It’s the same principle as sunning your clothes on a windy day. Without moisture in soil, micro-organisms and earthworms die. Without moisture in soil, roots can’t bring water up to leaves.
- Energy wastage: Plants would have to expend energy to resist wind to stay upright. They would be reaching for the sun but pushed sideways by the wind. The wasted energy could be better used for biomass growth or food production. Compared to trees, grasses deal with wind much effectively. That’s the reason you see so much lalang on this site!
- Mechanical damage: Malaysia is quite sheltered by surrounding islands and typically do not suffer from typhoons. However, there are still windstorms that can uproot big trees. Even if the plant is well-rooted, the leaves can be mechanically damaged by the wind itself or rubbing against other leaves.
