Top-soil erosion has been critical in the country and great efforts are being made to undo the harm caused by humans and the proliferation of human settlements in the hilly regions.

One should not create his/her own trails through previous un-trailed parts, especially down slopes, when trekking. This might lead to the formation of a watercourse during heavy rains and lead to erosion and landslide eventually. 

Avoid walking around mud patches, as this would increase their size every time it is done. Walk through it instead. 

Take care not to uproot any foilage, especially regenerating ones. Do not pluck out any of it, in the hills. 

Camp fires are not forbidden, but as in the western world, the same do's and don’ts apply here. Put off camp fires before proceeding further on the trek / trail. Never leave the site with an ember burning. That, during a dry season could lead to catastrophic forest fires. 

By cutting wood one will be contributing to deforestation. It is recommended that one carries his/her own supply of fuel (kerosene or disposable gas cylinders) for all cooking needs, etc. Appropriate clothing should be utilised to keep oneself warm. Avoid a situation, where lighting a fire is necessary in order to keep warm.
