Protection of forests from fires is necessary for preservation and development of forest-industrial regions of Russia. Despite years of research, the problem of detection, prevention and extinguishing of forest fires has worsened in many countries of the world. Using the methodology, patentable solutions have been developed to prevent and extinguish forest fires by cutting wood-shrub vegetation while continuously moving basic forest machines.

The analysis of patents of the Russian Federation in the field of removal of undesirable trees and bushes at continuous movement of the forest tractor is given for formation of knowledge base.

На основе анализа патентов Российской Федерации в области удаления нежелательных деревьев и кустов при непрерывном движении лесного трактора предложены и запатентованы новые технические решения.

With the functional-structural-technological analysis, the knowledge and form of their representation in relation to the improved object of knowledge technology and the form of their presentation are systematized according to the example of brush-cutting and mulching techniques for cutting undesirable trees and bushes.

The article describes a noctuid moth Cosmia affinis as a pest of deciduous trees. The main purpose of the work is to determine the percentage of damaged deciduous trees of different types, which were damaged by the pest noctuid moth and the influence of climatic factors on their numbers. The main work results are the following: calculated percentage of the trees leaf blades damage, the researcher has indicated the percentage of deciduous trees, damaged by noctuid moth, presented a phenocalendar of a noctuid moth Cosmia affinis development and the occurrence of pests’ frequency in number.

The article describes a chinch bug Arocatus melanocephalus as a pest of deciduous trees. The main purpose of the work is to determine the percentage of damaged deciduous trees of different types, which were damaged by the pest bug and the influence of climatic factors on their numbers. The main work results are the following: calculated percentage of the trees leaf blades damage, the researcher has indicated the percentage of deciduous trees, damaged by bugs, presented a phenocalendar of a chinch bug development and the occurrence of pests’ frequency in number.

The complex of objects of intellectual property in the field of protection of linear objects and prevention of forest fires is shown by cutting trees and bushes with continuous movement of the machine.

A brief review of the research aimed at improving technologies and equipment for the removal of trees and bushes on felling and line facilities is carried out. Particular attention is paid to the machines for performing these operations with the continuous movement of the machine.

The experience of improving the process of skidding with tractors with manipulators is given. The developed technical solutions are described.

The opinion was expressed and the need to accelerate the development work to solve the problem of cutting trees and bushes with the continuous movement of the forest machine.

The modern tendencies of creation of technics for clearing of cuttings down and linear objects are considered. Technical solutions for grinding trees, bushes and stumps using mulchers have been proposed.

New patents of intellectual property patented by Petrozavodsk University on the construction of equipment for protecting linear objects and preventing forest fires by cutting trees and bushes with continuous movement of the machine are given.

Considered a range of technical requirements for the creation of machines for cutting of trees and bushes in a continuous motion machine in the protection of linear objects and creating firebreaks.

The article describes a chinch bug Kleidocerys resedae (Panzer, 1797) as a pest of deciduous trees. The main purpose of the work is to determine the percentage of damaged deciduous trees of different types, which were damaged by the pest bug and the influence of climatic factors on their numbers. The main work results are the following: calculated percentage of the trees leaf blades damage, the researcher has indicated the percentage of deciduous trees, damaged by bugs, presented a phenocalendar of a chinch bug development and the occurrence of pests’ frequency in number. The author concluded that the main limiting factor, affecting the increase in the number of bugs is a high moisture level in Almaty.

It shows that the development of technology for continuous cutting of trees and shrubs is going towards the creation of multi-functional machines fit into the flexible technology of timber production.

An assessment of devices for clearing of trees and shrubs runs power lines, care for ordinary forest plantations on cuttings, removal of woody undergrowth on oil and gas pipelines, clearing zakustarennyh areas in agriculture.

Considered a range of studies carried out in Petrozavodsk university, is provided in the beginning of the study brush cutter, and then devices for continuous cutting of trees and bushes on the linear objects.

An overview of the work aimed at evaluating research in the study of technology removal of trees and bushes in the continuous cutting of them.

Proposed cleaning machines for linear objects from trees and shrubs, as well as creating firebreaks.

The necessity of creating a specialized forest machines for cleaning of linear objects from trees and shrubs, including to improve their fire safety.
