Issues affecting BNHS
Negative issues
Humanly ignited forest fire by tribes is bad for the health of the ecosystem.
Film city throws garbage in BNHS and the crows come and eat the garbage but also the worms which are the food of the other birds and the crows destroy the birds ecosystem.
The nonnative plant comes and harms the plants from growing, it is called Gilicidia plant and it is from America. It can survive without water, but it got the correct climate and soil here. It harms the plants from growing by sucking water from the ground and it has no value ,(it is like a pest.)
Land encroaching =Builders want to build buildings inThe BNHS land and cut down trees which increases global warming, building buildings in BNHS is building it on illegal land.
Positive issues
They are planting butterfly host plant and the butterflies lay there eggs there because when caterpillars hatch they only eat a specific plant.
When the rainy season goes the animals get very thirsty so they have started making water holes so when the rainy season comes back they flush the holes with water.
