By comparison the Picture you see below is from the chocolate hills of Bohol. The hills are made of limestone and very poor quality soil. But as you can see they are lush with grass.

In the summer months the grass turn brown hence the name chocolate hills. The point we are trying to make here is that the government can start a few of the native Cogon grass in the Bald mountain of Pulag. Cogon grows very fast. Its roots grow deep. You can burn it down and the next rainy season it is back up again. Where Cogon grows, bamboo will grow. They are symbiotic. Cogon helps keep the rain water in the soil where the bamboo needs it.
Cogon also grows very well with the Tamarind tree (Sampaloc). The sampaloc tree grows very deep deep roots and can withstand 6 to 8 months of drought. The sampaloc is excellent for lumber (red hardwood). The sampaloc can have a symbiotic relationship with the cogon grass.
