Q&A: What native Philippine tree to plant when starting up a RAINFORESTATION PROJECT? .... KUPANG (Parkia Timoriana) is what I would suggest.

In my opinion, I would suggest "KUPANG" with scientific name Parkia Timoriana (also known as P. Javanica) as ONE OF THE BEST PHILIPPINE NATIVE SPECIES TO PLANT WHEN STARTING A RAINFORESTATION PROJECT. This is due to the following reasons:

Fast growing. This pioneer tree will be able to give ample sun and shade to other shade loving premium forest trees growing under it.

Leguminous tree. It is able to fix its own nitrogen requirements with the help from a soil bacteria called rhizobium that live within the roots of leguminous plants and trees, thus it can grow with even the poorest type of soil. The roots together with its fallen leaves will provide nitrogen that will be beneficial for other trees within its proximity, bringing back soil fertility that was lost from continued harvesting of crops.

Sun loving and shade tolerant. It is able to grow under full sunlight and is also able to adjust under shaded areas, therefore this tree will still thrive under opposite conditions.

Easy Access. Seedlings are readily available at the Manila Seedling Bank. Since the tree is able to produce numerous seeds within seedpods, there will always be a steady supply of seedlings to grow. A fairly common tree especially in Metro Manila, Laguna and other parts of the country.

High germination rate and good viability of seeds upon long storage. Some seeds that I have stored for two years now are still germinating upto today when sowed.

Unreceptive to pests and diseases and will easily outgrow grass and vines. I think that this is a common characteristic that leguminous tree species share and possess. They are very hardy especially when established in full sun.

Branches are flexible and strong enough from wind breakage. Branches and trunk seem to sway whenever there are strong winds. It can hold its stance and never have I seen it topple down or break its limb. However, I must admit that I haven't seen a mature Kupang tree under the mercy of a strong typhoon. (will follow-up on this issue upon confirmation)

Medicinal. I have read that the bark and leaves of this tree is made into a poultice and applied to skin infections and sores. The bark is also used to treat diarrhea and dysentery. Seeds are said to treat persistent abdominal pain.

Edible. According to some literature, the pods and seeds are edible. Although I haven't tried it, I will certainly welcome the idea of tasting this delicacy. Roasted seeds are used in Africa similar to coffee called Soudan coffee.

Source of lumber. The lumber from this tree is often used for light construction.
