Calculation of ecological and economic damage in forest management from insect pests

Abstract

The work is devoted to the development of the methodology for assessing ecological and economic damage from insect pests in dark coniferous forests of Siberia. On the basis of field data and generalised methodology, the results of calculation of income losses from direct and indirect damage caused by the impact of Ussuri Polygraphus on the fir forests of Krasnoyarsk Krai are presented. The complex monetary assessment is made on the basis of losses of marketable qualities of wood, oleoresin, fir boughs and loss of ecological functions - carbon-depositing, oxygen-producing and water-protecting. The proposed variant of calculation is possible to adapt the assessment of damage caused by various secondary pests and as a result of mass impact of the Siberian silkworm.
