This paper presents the First report of an ongoing to study the effects of trees on radio signals at microwave frequencies. The effects of vegetation media on the planning and design of radio links at microwave and Microwave frequencies are considerable and must be accounted for by radio system operators and users. Measurements have been made to determine the extent of attenuation when propagated through vegetation and also have been carried to be conducted on selected vegetation with various degree of foliation to determine the dependence of losses on vegetation. Also, path geometry and tree geometry are among other parameters under consideration. The results from these experiments compared with standard ITUR-P empirical models and to reflect the dependence of vegetation attenuation on the input parameters under observation.
