Riverine forests: Patches of riverine forests occur along streams and rivers, and include plant
communities such as gallery forests dominated by tall trees, short scrubland/bushland and bamboo
thickets. The riverine gallery forests are dominated by tall tree species such as Terminalia spp. The
riverine scrubland/bushland includes species such as Homonoia riparia, and others such as
Telectadium, Phyllanthus and Crateva spp. These bushland are inundated by floodwater, during the
rainy season.
Forest plantations: The scattered patches of forest plantations in the two provinces include Kapok
(Bombax ceiba), Cashew (Anacardium occidentale), Blackwood (Aquilaria crassna), Rubber (Hevea
brasiliensis), Acacia (Acacia auriculiformis and A. mangium) and Coffee (Coffea arabica).
3.3 Species richness of flora in the survey areas
Plants used by local communities: Based on field observations made during current survey and
information gathered from local communities, the plant species used by local communities in the five
districts ranged from 40 species (Nong District) to 90 species (Vilabouri District) (see Table 3.5, and
Annex 3.1 – 3.5). The plant products and life-forms used by local communities included timber species
(trees), fuel wood (trees and woody scrub), fruits (in trees and woody scrub), yams and tubers (from
herbaceous plants), medicinal plants (woody and herbaceous plants), edible shoots (bamboo and
rattan), animal fodder (grasses and other woody/herbaceous plant leaves) , tannins/resins and plant
material for household uses, including weaving of mats and baskets (ie., bamboo, rattan, reeds etc.)
(see Annex 3.1-3.5 for details).

Composition of plants in the survey area: Based on current observations and information compiled
from secondary sources, more than 500 species of plants have been recorded from the Salavan and
Savannakhet provinces (see Annex 4.5 for consolidated plant list). Among the total plants recorded
from the survey area, 14 woody plant species are globally threatened (Table 3.6). A majority of the
globally threatened plants are dipterocarps.
