Part 1 – A Rapid Participatory Biodiversity Assessment - IUCN

Over-exploitation of
timber species by
Vietnamese timber
merchants
Improper forestry
practices leading to
damage of non-target
plant species; Lack of
regulation and
monitoring of timber
extraction operations;
Income opportunities
for selected influential
villagers and
administrators; lack of
village empowerment
Poaching High demand for wild
meat by Vietnamese
timber extraction
workers (ie., truck
drivers and labourers);
scarcity of domestic
animals due to disease
Spread of invasive
alien plants
Harmful fishing
practices (is., use of
small-mesh size nets)
related mortalities
Forest clearance for
swidden cultivation and
timber extraction
Decrease of forest
biodiversity and related
provisioning services;
Decrease of surface
and ground water
resources;
Heavy erosion of soil
leading to siltation of
streams and rivers
Decline of reptiles,
birds and mammals
Decline of native plant
biodiversity
Food scarcities Decline of freshwater
fish species
households during
rainy season; dry
season water scarcities
affecting households
and livestock;
Decrease of timber
species and other
forest products for
domestic use; Flash
floods affecting bank
cultivations and
households during
rainy season; dry
season water scarcities
affecting households
and livestock;
Loss of income
opportunities related to
ecotourism; Increase of
crop damage due to
proliferation of rodent
pests; Scarcity of wild
meat for domestic
consumption
Human health
implications (ie.,
increased respiratory
diseases due to
seasonal spread of
Siam weed pollen);
Decrease of NTFP’s
from native plants
3.8 Potential impacts on biodiversity related to the plantation project
Potential negative impacts of plantation projects on biodiversity include
Decline of fish for
domestic consumption
o Increased pressure on forest and wildlife resources
o Over-exploitation of wild animals and plants due to improved access through new road
networks
� Illegal poaching, felling of timber species and over-exploitation of NTFP’s
o Fragmentation of habitats and/or disruption of seasonal migratory routes of wild animals
o Accidental mortality of wild animals (related to clearing operations and road-kills)
o Spread of fire into wild habitats during the clearing phase
o Further conversion of primary forests into swidden cultivation by villagers (to continue the
shifting cultivation practice in new areas, due to loss of fallow lands for the forest
plantations)
o Potential degradation of aquatic habitats (and resultant impacts on aquatic organisms that prefer
pristine waters)
