• Luot Mountain are relatively homogeneous with low hills, with little division, consisting of two successive hills running about 2 km in the east to west direction. • A peak with an absolute height of 133m. The other peak has an absolute height of 76m, the average slope is 150, where the steepest is 270. • Direction main in the northeast, northwest and southeast. The topography is favorable for afforestation. Some indigenous species have been planted here: Erythrophleum fordii (Lim xanh), Dalbergia tonkinensis Prain (Sua bac bo), Fernandoa (Dinh thoi). In places where big sloping is prone to erosion, it is important to plant broadleaved and staggered species
