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.
