Development of technology for standardization of parameters of winter route registration of game animals

Abstract

The need to develop a new technology for planning survey routes is caused not only by the difficulty of implementing the recommendations of the current methodology for winter route accounting (ZMU) for the “equidistant placement” of survey routes with “observance of a proportional survey of land categories forest, field, swamp”, but also by the inability of the method of grouping the sample into categories of land to reduce the heterogeneity of the examined material. To standardize the placement of accounting routes, the technology of stratification of the territory is put, in which the virtual boundaries of the stratum serve to determine the extrapolation area and the location of the survey route. For the total area of the hunting farm, a tabular, or calculated (for farms with a different area), value of the route length standard, km/thousand ha, is established. The free navigation program SAS Planet determines the length and width of the territory within the boundaries of the hunting area and the principle layout of the registration routes in the strata. According to the algorithms, the following parameters are calculated: the total length of the routes, the average values of the length and width of the territory, the number of strata, the distance between the registration routes, the length of the route in the stratum, the area of the strata, which are necessary for designing the stratification of the territory. On the example of a specific farm with unknown values of parameters, except for the area of the territory, the suitability of algorithms for calculating parameters is shown; a map of the boundaries of the strata and the location of the accounting traces was created; the area of the strata and the design length of the registration route in each stratum were determined; digitized files of traces necessary for work on their reference to the terrain have been created; the technology of binding is given. The results of the study confirmed the manufacturability and simplicity of the method for localizing routes and extrapolation sites, as well as the compatibility of their ordered placement in compliance with a standardized sample size for territories with any area and boundary configuration.
