Give yourself plenty of daylight to find a campsite and get setup. Use existing campsites where ever possible. Campsites should be 100m from water sources like creeks and on a durable surface.
Pre planning is the key to many of the minimal impact techniques. Please consider the following points when planning, packing for and speaking to people about your trip.
Ensure each person in your group is understands and is committed to these behaviours
It is possible to measure the impact of a campsite a year after it was used (Even when used for just one night). It is best to use an existing campsite to keep the damage localised to a small area, rather than generating many camping scars.
100m from water
There are several reason for camping away from water. Firstly it minimise the chances of contaminating the water with disease or nutrients. It also allows a wildlife corridor making sure that animals can get to their water source without becoming to comfortable with humans. Finally it makes it easier to collect water without creating a new track.
Minimise activity around the campsite
Activity such as walking, running and playing games, compacts soil and can kill plants. So pick the most durable and already disturbed surface for any activity and keep to a minimum.
Soft Shoes.
Hard boots cause more damage to the ground you walk on when compared to softer shoes for several reasons – see keep on track rational for more info.
