Forests are the precious natural resources which provide us wood, timber tree, human living essentials and it is the place where flora and fauna live. It helps in balancing the eco system.. But the greedy mankind destroys this natural resource legally and illegally there by eco system gets unbalanced. The prime of the way of exploiting these forest resources is cutting the trees. To conserve the illegal logging of forest wood we proposed a Wireless Sensor Network based remote forest monitoring and conservation of illegal logging of valuable trees. This system is suitable for large-scale forest monitoring from illegal logging. We have used a cluster of sensor nodes to monitor the cutting of trees. Periodically the sensed data will be transmitted to the monitoring centre, where it will be recorded.
