forest area, sometimes they will extinct. Therefore, we collected V. wightii along with road
side. Based on section 38 explaining the Biological Diversity Act 2002 central government

announcement, the V. wighii is rare and need to conserve it. We have not collected a healthy
orchid, but the orchid collected by us is dying due to termite over the bark of host and falling

off from the host. So we collected that and conserved them.

The collected orchid is conserved in two states, as the pictures (Figure. 1) shown, we
tied it to the host tree (Psidium guajava and Hibiscus rosa-sinesis) and some of them grown in

pots with help of growing supplements known of red bricks, charcoal and coco peat for

increase in moisture holding capacity. sometimes chance to dry up itself and also some high
much of watering can causes the decay by algal attack. Therefore, the orchids are carefully

maintained under the controlled environment (orchids grown under original climatic
conditions, or else we can say, based on studies of their native conditions) called ecological

parameters like temperature, humidity, light and nutritive conditions. Usually, the orchid
grown under the tree shades with filtered sunlight for photosynthesis purpose. Because Vanda

wightii has a thin leaf and if more sunlight, it can cause leaf by sunburn later it will die off.

CONCLUSION:
Orchid conservation is now a matter of global issue. Protection of valuable orchid species in

their natural habitats is an urgent need as orchids are very sensitive to the disturbances
occurring in nature like global warming, pollution, forest fire, habitat destruction, etc. Illegal

trading of wild orchids from nature from one place to another place is another impact.
Conservation of orchids can be done by collecting wild orchids which are going to be not

available in future due to road widening, pollution, etc. and should be conserved in

undisturbed habitat like farms, house gardens and colleges. Conservation programs should be
conducted in colleges about endangered orchids and how to conserve them. Their natural

habitat should be conserved. Giving idea of orchid culture for young generations to conserve

and divide them. We are conserving Vanda wightii Rchb.f. which are going to be threatened
due to pollution, road widening, etc. Government should establish more conservation center

for orchid as an ex-situ conservation.
