Abstract-Wildlife prevention has become an important practice due to negative effects of human activities such as cutting of trees on large scale and unregulated hunting which causes major threat to wildlife. So we are going to introduce the project on prevention of trees and wildlife in forest. This article presents the design of a system for detection of vibration for prevention of cutting of trees, detection of temperature for prevention of forest fires also detection of pulses of animal for prevention wildlife using wireless sensor networks to prevent a disaster (forest) that could lead to loss of a significant number of natural resources. In this project, The sensing device can sense the vibration, pulse, and temperature, and then sent them over zig-bee networks to forest office. To save the transmission cost, we also sent the GPS location information simultaneously. Here we use Wireless Sensor Networks (WSNs).In this network numerous sensors are usually deployed on remote places, the deployment and maintenance must be easy and scalable. Wireless sensor network is the network which consists of large number of small nodes. Sensor nodes are great for deployment in hostile environments or over large geographical areas.
