Abstract. A mathematical model of the interaction of electromagnetic radiation of the VHF range with forest vegetation is described. The forest medium is represented in the form of two-dimensional collections of randomly arranged cylindrical elements with random values of geometric parameters and permittivity. The calculation is carried out by the method of self-consistent equations. The main features of wave propagation in the forest environment in this range at small distances between antennas are discussed: the dependence of attenuation mainly on the density of the forest, a decrease in attenuation with increasing frequency, the possibility of resonant interaction of radiation with vegetation elements. A comparison of the results of computational and field experiments is carried out.

Key words: forest media, specific attenuation, scattering, transmission spectrum, numerical experiment.
