Method for crosscutting of stacked trees
SUBSTANCE: invention relates to timber industry and can be used to separate a pack stacked trees during mass forest harvesting using skidder-processor machines. Method of crosscutting stacked trees implemented by a forest machine equipped with a manipulator with a harvesting head includes guiding jaws of the harvester head to a tree located in the pile, grabbing the tree, pulling the tree through the working members of the harvester head while bucking boughs and block cutting. Prior to grabbing a tree from the pile the tree is moved relative to other trees by a disconnector. Disconnector is installed on the handle of the manipulator in such a manner that there is free space between trees that are next to each other in the pile; said space is sufficient for free passage of the jaws of the harvester head that are able to grab a selected tree.
EFFECT: method increases efficiency of crosscutting of stacked trees using a harvester head.

SUBSTANCE: invention relates to technologies of forestry and logging industry. The method comprises measuring the length and diameters of the trunks in the bark along the length of the trunks and in butt sections. 100 trees non-doted in shape are taken, in which the length of the trunks is measured, as well as the diameters in the bark in the butt, the trunk diameters in the bark starting from the butt sections to the tops of the trees, and the trunk diameters at half the length of the trunk.

SUBSTANCE: invention relates to environmental monitoring of areas with grass cover. The method comprises allocation on the small river or its tributary visually on the map or in-situ of the site of floodplain meadow with grass cover. The marking on the allocated site along the flow of the small river or its tributary is carried out in characteristic places of at least three cross-sections in the transverse direction. The marking along each cross-section is carried out of at least three test sites on each side of the small river or its tributary. On each test site a frame is placed with the inner sides of least 0.50×0.50 m. Then, flush with the surface of the soil the aerial parts of certain plants or their portions are cut in the form of several plants of the same species present at the test site. Then, the cut portions of the plants are laid in separate piles on the species of grass. After cutting all the blades of grass from all the test site the piles of grass are immediately weighed on a portable scale. After weighing the piles of grass are thrown away. Weighting procedure with throwing the weighted plants is repeated at each test site on the allocated area. Then the total weight of freshly cut grass is calculated by species of grass. At each separate test site the weight of the sample of the freshly cut grass is calculated as the sum of the weights of separate piles by species of grass. The total weight of the plant species is calculated as the sum of all the piles of cut grass on species from all test sites. Then, on the certain species of plants for all test sites the rank scale of the grass species is made on the freshly cut mass. The ranks are arranged with increase in the total weight on the site. Assessment of the species composition of the grass cover is carried out by statistical modelling by identifying the mathematical models of mass change of cut grass on the site and on a separate test site depending on the rank of species of grass and herbaceous plants.
EFFECT: technology enables to increase the accuracy of accounting of the presence of species of grass and herbaceous plants, with simultaneous simplifying the evaluation process of species composition.

Further, according to the results of the measurements obtained, the statistical modelling is carried out with the definition of the correlation coefficient of the obtained statistical models on the measured parameters. According to the correlation coefficient the ecological assessment of the status of the territory is carried out.
