The article systematizes the experience of solving the task of transport modeling for the ground access to the forest fires and forest resources, presented by scientific and engineering works. General characteristics of transport modeling based on the Russian and foreign experience are given; the analysis of data services and Open Source developments are the topical subjects in the development of transport projects. The main attention is paid to the review of issues of transport modeling issues in the use, protection, and reproduction of forests, taking into account the current Russian regulatory documents of the forestry. We have described the geodata sources, as well as using remote sensing data of different types and spatial resolution for the transport modeling in the forestry. The works of scientific and educational institutions represent Russian research on the forest transport modeling and forest infrastructure. They have a common understanding of forest transport accessibility as a complex issue. It is noted that the interest of researchers traditionally lies in solving environmental and economic problems of modeling. It is necessary to continue the work on the modeling for the location of fire stations, cutting areas and forest warehouses for the model territories in different regions and of different forest infrastructure’s characteristics. The development of methods and technologies to balance the infrastructural load and natural stability of forest ecosystems is described as a direction for further research. Undertaken review shows some patterns of forest transport modeling as a part of forestry using modern applied geoinformatics.

Comprehensive data on natural hazards and their consequences are crucial for effective for risk assessment, adaptation planning, and emergency response. However, many countries face challenges with fragmented, inconsistent, and inaccessible data, particularly regarding local-scale events. To address this data gap in Russia, we developed an end-to-end processing pipeline that scrapes news from various online sources, ...

Cloud shadows lead to alternating light and dark periods at the surface, with
the most abrupt changes occurring in the presence of low-level forced cumulus clouds.
We examine multiyear irradiance time series observed at a research tower in a midlatitude
mixed deciduous forest (Harvard Forest, Massachusetts, USA: 42.53◦N, 72.17◦W) and one
made at a similar tower in a tropical ...

We examine the physical and biological responses of forest canopies to step changes in light
caused by passing low cumulus clouds that intermittently block the direct solar beam. Using
data obtained at a tropical rainforest and at a midlatitude deciduous forest, we estimate the
course of sensible heat flux, net ecosystem exchange, evapotranspiration, and water-use efficiency in response ...

We examined the net-ecosystem-exchange (NEE)-based annual carbon-balance estimates
obtained from eddy-covariance (EC) measurements at an unmanaged sedge-grass marsh
ecosystem (Tˇreboˇn, Czech Republic, 49°1′ N, 14°46′ E), seeking methods to improve the EC
measurements in inhomogeneous environment. The data filtering procedure was developed
using three thresholds: (a) a stationarity test; (b) a stability u∗-threshold; and (c) a high relative
humidity RH-threshold. ...

Soil respiration (SR) is a main component of the carbon cycle in terrestrial ecosystems,
and being strongly affected by changes in the environment, it is a good indicator of the ecosystem’s
ability to cope with climate change. This research aims to find better empirical SR models using
25-year-long SR monitoring in two forest ecosystems formed on sandy Entic ...

Оценка дыхания почвы - одного из основных источников углекислого газа в атмосферу – необходима для корректного определения углеродного баланса в наземных экосистемах. Сравнение пульсационного и камерного методов измерения дыхания почвы, проведенные в березняке постагрогенном в регионе южного Подмосковья, показывает хорошую сопоставимость этих методов с коэффициентом детерминации R2=0.75 (p-value=7.546e-12).

On certain kinds of cloudy days, many forested ecosystems exhibit enhanced carbon uptake and water-use efficiency-the cloudy-day forest flux anomaly. Using ensemble methods to analyze eddy-covariance fluxes, we have
diagnosed net ecosystem exchange (NEE) and water-use efficiency (WUE) of a temperate broadleaf forest and a
tropical evergreen forest as they responded to natural fluctuating-light regimes. Here we ...

Carbon dioxide (CO₂) efflux from soil (or soil respiration, SR) is one of the most important yet variable characteristics of soil. When evaluating large areas, CO₂ efflux modeling serves as a viable alternative to direct measurements. This research aims to identify site-specific differences and their effects on empirical CO₂ efflux modeling. The experimental data from ...

Natural regeneration of forest soils affected by agricultural practices is a common phenomenon in many regions worldwide, particularly in boreal ecosystems. Affecting soil quality, the partitioning of extractable fractions of heavy metals and metalloids (HMMs) is not studied during natural regeneration. The following stages of natural regeneration after plowing have been identified in the Smolenskoye ...

Late Pleistocene transformation of European glacial landscapes is often narrowed down to the impact of
postglacial linear erosion. Yet in the marginal zone of MIS 6 glaciation extensive watersheds were protractedly
affected by the postglacial flattening in periglacial and interglacial conditions. Local sediment sinks such
as kettle holes and dry valleys infilled throughout the postglacial stage can serve ...

We present a methodology for calibrating doubly constrained gravity models. Three types of deterrence functions are examined: exponential, power, and combined. The latter includes two calibration parameters, whereas the others contain only one. The parameters are identified so that the model reproduces the observed trip length distribution with high accuracy. We test four optimization methods: ...
