Aiming at the existing problems of forest information monitoring

such as complex environment

limited monitoring range and low precision

a novel method using wireless sensor networks（WSNs） to monitor temperature humidity and illumination intensity information of forest environment is presented

and forest information monitoring system is developed. WSNs uses improved collection tree protocol（CTP） routing protocol for selforganization

and collects information timely and sends it to back-end for data processing and analysis.In order to comprehensively monitor distribution of forest information

the Kriging interpolation algorithm is used for interpolation prediction on blind area without sensor nodes in forest. Forest information distribution is displayed through visualization system interface intuitively. The experimental results show that the accuracy of the proposed forest information monitoring method is higher.
