Flora and Founa
The flora in Ratanakiri is very divers. The tropical dry forests main categories are the mixed forest, secondary and primary forest. Within these forests many varieties of vegetation occur like natural bushy savanna and grass savanna.

During our tour researches we catalog the most common trees. We have listed the trees with a picture of the trunk and the canopy for easy identification. Next to the Latin and English names, we briefly list the purpose of some of them.

Dipterocarpus is a genus of flowering plants and the type genus of family Dipterocarpaceae. The genus has about 70 species, occurring in Southeast Asia. It is an important component of dipterocarp forests. Its generic name comes from Greek and means "two-winged fruits". The genus is of considerable importance as timber trees, sold under the trade name Keruing, although not as important as Shorea.

Tree green to  evergreen. Fruit in the form of resins. Local purpose; As shown on the inlay picture of the trunk, local people fire up the notching in order to make the trees fluid flow. Once the fluid is collected it is  used to seal up wooden boats. 

These trees are a source of a damar resin used in varnishes. The wood is finely grained, very durable, and used for making boats , bridges , and furniture

While various species and cultivars are able to fill a wide variety of landscape needs, crape-myrtles are chiefly famous for their colorful and long-lasting flowers. Most species of Lagerstroemia have sinewy, fluted stems and branches with a mottled appearance that arises from having bark that sheds throughout the year. The leaves are opposite, simple, with entire margins, and vary from 5-20 cm (2-8 in). While all species are woody in nature, they can range in height from over 100 feet to under one foot; most, however are small to medium multiple-trunked trees and shrubs. The leaves of temperate species provide autumn colour.

Flowers are borne in summer and autumn in panicles of crinkled flowers with a crepe-like texture. Colours vary from deep purple to red to white, with almost every shade in between. Although no blue-flowered varieties exist, it is toward the blue end of the spectrum that the flowers trend, with no sight of orange or yellow except in stamens and pistils. The fruit is a capsule, green and succulent at first, then ripening to dark brown or black dryness. It splits along six or seven lines, producing teeth much like those of the calyx, and releases numerous small winged seeds.

The timber of some species has been used to manufacture bridges, furniture and railway sleepers.
