The paper presents results of 4 protected areas investigation within the river Vyatka flood plain. We have conducted a floristic research in accordance with a hierarchy system of floristic complexes by a type-class-group principle, and classified vegetation. 3 types of floristic complexes (forest, meadow, and water), 2 classes (hilltop-flood plain, ridge and natural) and 8 groups of floristic complexes were defined. Small-leaved forest floristic complexes is presented by the following forest types: mixed-herbs-Aegopodium aspen forest, mixed-herbs aspen forest, herbaceous boggy birch forest, cowberry birch forest, aspen-linden birch forest, bilberry-herbaceous birch forest, and mixed-herbs-Filipendula alder forest. Dark coniferous floristic complexes are presented by bilberry spruce and herbaceous spruce forests. Light coniferous forest floristic complexes are: cowberry-herbaceous pine, green-moss-cowberry pine, and stone-bramble-herbaceous pine forests. Broad-leaved forest floristic complexes are presented by flood-plain oak and aspen-linden herbaceous forests. Oak ( Quercus robur L.) is also marked as an undergrowth component of deciduous and coniferous phytocoenoses. Flood-plain meadow floristic complex is formed by gramineous-mixed-herbs and Filipendula-Calamagrostis-mixed-herbs associations. Former river-bed floristic complex is marked within all studied objects. Communities with high level of biodiversity are restricted to water and hilltop-flood-plain ecotopes. Species richness of studied communities varies within 15 to 43 species. Less diverse ecotypes are ridge types. Investigated floristic complexes are habitats of rare and relict species of Kirov Region flora. The study of partial flora composition is a base for vegetation monitoring.

Abstract Taking the litter layer of three typical plant communities (broad-leaved forest, coniferous forest, and shrubs) as the research object, this study analyzed the hydrological function characteristics of the litter layers of different typical plant communities using the indoor immersion method in order to reveal the effects of the traits of the litter layer on the hydrological functions of typical plant communities in the core area. The results showed that: (1) the litter reserve change trend decreased in order as follows: broad-leaved forest (13.31 ± 1.54 t/hm2) > shrubs (12.62 ± 2.34 t/hm2) > coniferous forest (11.36 ± 1.43 t/hm2). The coniferous forest and shrub litter reserves increased significantly with the increase of decomposition degree (F = 19.36, P < 0.01; and F = 9.19, P < 0.01, respectively), while the broad-leaved forest litter reserves decreased first and then increased significantly with the increase of decomposition degree (F = 25.70, P < 0.01); (2) the litter natural moisture content change trends were as follows: shrubs (34.09 ± 4.31 t/hm2) > broad-leaved forest (31.32 ± 1.76 t/hm2) > coniferous forest (29.48 ± 7.02 t/hm2). The change trends of the maximum water-holding capacity, maximum interception amount, maximum interception rate, effective interception amount, and effective interception rate were in descending order as follows: broad-leaved forest > shrubs > coniferous forest. The maximum water-holding capacity, maximum interception amount, and effective interception amount of litter rose with the increase of decomposition degree. The broad-leaved forest community litter layer had the strongest rainfall interception function and the best hydrological service functions. The interception function was stronger with the increase of the decomposition degree of the litter layer; (3) the water-holding and water-releasing capacity variation of the litter layers manifested as reversed “J” features for the three typical plant communities. The water-holding capacity of different plant community litter layers (Qct) was significantly positively correlated with time (t) (P < 0.01), and the equation was Qct = b + alnt, whereas the water-releasing capacity of different plant community litter layers (Qst) was significantly positively correlated with time (t) (P < 0.01), and the equation was Qst = a t b; and (4) the water absorption and release rates of the litter layers had four periods. The water absorption rate (v) was significantly negatively correlated with time (t) (P < 0.01), and the equation was v = a t− b, while the water release rate was the same. The water absorption and release rates differed by one order of magnitude in the first 5 min, exhibiting the greatest regulation and storage function, while the rate differed by only 2.1–4.5 times during the last three periods. This shows that the litter layer has the strongest rainfall regulation and storage function for only a short period of time before declining.

Boreal forest is a sensitive indicator of the influence of climate change. It can quantify the level and spatial divergence of forest change for forest resources and carbon cycle research. This study selected a typical boreal forest affected by few human activities as a research area, in Siberia, with a latitude span of 51°N–69°N. A total of 150 Landsat images of this area acquired in 1985 and 2015 were collected. A hierarchical classification approach was first established to retrieve the information of forest cover and species. The forested and nonforested lands were discriminated by the decision tree method and, furthermore, the forested land was classified to broad-leaved and coniferous forests by a random forest algorithm. The overall accuracy was 90.37%, which indicates the validity of the approach. Finally, the quantitative information of the forest cover and species changes in each latitude zone of every 2° was analyzed. The results show that the overall boreal forest cover increased by 5.11% over the past three decades, with broad-leaved forest increasing by 3.54% and coniferous forest increasing by 1.57%. In addition, boreal forest increased in every latitude zone, and the spatial divergence of the changes of the boreal forest cover and species in different latitude zones were significant. Finally, broad-leaved forest increased more rapidly than coniferous forest, and the greatest increase, of up to 5.77%, occurred in the zone of 55°N–57°N.

Land-Use Cover Changes (LUCCs) are one of the main problems for the preservation of landscapes and natural biodiversity. Protected Areas (PAs) do not escape this threat. Poland is among the European leaders in terms of the variety of landscapes and the share of an area designated as a protected area. However, as many as 78% of the habitats have poor or bad conservation status based on EEA reports. This article analyzes the LUCCs between 2000 and 2018 in various types of the Polish legal forms of nature protection areas and the European Natura 2000 network within the country. The research material was: the data of Corine Land Cover (CLC), the Central Register of Nature Protection Forms, and high-resolution layers, such as HRL and orthophotos. The results were compiled according to the CLC class and forms of protection. The matrix of transformations showed that the most frequently transformed CLC class was 312 (coniferous forest). It was transformed into class 324 (transitional woodland shrubs). The changes in PAs were usually smaller than in the surrounding buffer zones, which may indicate their effectiveness. The exception was the areas of the European Natura 2000 network. The scale of land-cover flows (LCFs) changed within particular forms of protected areas, though afforestation and deforestation predominating in all area types. National reserves and parks were the most stable in terms of land cover structures. However, human settlements increased around the protected areas, potentially increasing threats to their ecological integrity.

Land ecological security research has gradually become concerned field on global. Using on the Haba Snow Mountain as an example try to discuss the evaluation of ecological security based on change of the landscape ecological pattern in the paper. In GIS, RS and GPS support and accordance with the principles of landscape ecology and using new grid map method has been 1993 and 2006 Haba Snow Mountain ecological safety evaluation and space differentiation. There are temperate coniferous forest, grassland, sclerophyll broad-leaved forest, warm coniferous forest, water area, residential land, semi-humid evergreen broad-leaved forest, ice and snow land nine landscape types, and temperate coniferous forest and grassland are dominant landscape in the study area, both area has accounted about 67% of the total area. The results show that from 1993 to 2006 the whole landscape pattern has changed less in the area. Land ecological security level space differentiation is very obvious. Ecological security level high altitude area is superior to low altitude area, the core area is superior to the edge area, north area is superior to the southern area. Land ecological security in the study area whole is in good level. From 1993 to 2006 years land ecological security level has declined in the area. Research on ecological safety planning to provide basis for ecological safety planning and for similar high mountain canyon area also has reference value.

The spatiotemporal distribution pattern of the aerosol optical depth (AOD) is influenced by many environmental factors, such as meteorological condition changes, atmospheric pollution, and topographic changes. Understanding the relationship between the vegetation land cover and the AOD would favor the improvement of forest ecosystem services. This quantitative research integrated remote sensing and ground survey data and used spatial statistical methods to explore the drivers that influence the AOD of the exurban national forest park and analyze the differences between various forest types. The driver analysis was carried out in the hot (Z ≥ 1.64) and cold (Z ≤ −1.64) spots of AOD in 2010 and 2017. Our results showed that (1) the forest type was proved to be the main factor contributing to the AOD pattern and (2) from 2010 to 2017, the average growth rate of broad-leaved forest, coniferous forest, bamboo, and shrub in hot spots was significantly higher than that in cold spots, while there was no significant difference in the mixed forest. The average growth rate of biomass densities of bamboo, coniferous forest, and mixed forest were higher than that of the shrub and broad-leaved forest. These findings provided the guidance for the rational allocation of tree species to increase the biomass and improve the ecosystem service values of forest parks.

Saturated hydraulic conductivity (Ks) can be used to indicate changes in soil hydrology resulting from vegetation succession. A constant-head permeameter was used to investigate differences in Ks at five soil depths (10, 20, 40, 60, and 80 cm) along a successional sequence of 155 years in evergreen broad-leaved forest at Tiantong National Forest Park, eastern China. The following six forest successional classes were studied: climax evergreen broad-leaved forest (CE), sub-climax evergreen broad-leaved forest (SE), evergreen broad-leaved mixed coniferous forest (MF), coniferous forest (CF), secondary shrub (SS), and abandoned land (AL). Surface Ks (the geometric mean of Ks at 10 and 20 cm soil depths) significantly increased from AL to CE but declined in CF. The surface Ks value under CE was higher than under other successional stages (CE 271 mm h–1, AL 58 mm h–1, SS 124 mm h–1, CF 90 mm h–1, MF 170 mm h–1, SE 231 mm h–1), and was 4.7 times greater than under AL, 2.2 times greater than under SS, and 3.0 times greater than under CF, but showed no significant difference from SE (P > 0.05). Vertical difference of Ks was detected up to a soil depth of 40 cm along forest successional series. Macroporosity was the main determining factor and played an important role in the process of Ks recovery. The likelihood of overland flow generation was inferred by comparing Ks at soil depths of 10, 20, 40, and 60 cm under the various successional stages at prevailing storm intensities. Overland flow was most likely to occur in the early successional stages. This study suggests that Ks could be restored to climax forest levels along forest successional series, but the recovery time could be as long as 95 years.

The seasonal abundance of hard ticks that transmit severe fever with thrombocytopenia syndrome virus was monitored with a collection trap method every April to November during 2015-2018 and with a flagging method every July and August during 2015-2018 in Ganghwa-do (island) of Incheon Metropolitan City, Republic of Korea. This monitoring was performed in a copse, a short grass field, coniferous forest and broad-leaved forest. A total of 17,457 ticks (8,277 larvae, 4,137 nymphs, 3,389 females, and 1,654 males) of the ixodid ticks comprising 3 species (<i>Haemaphysalis</i> <i>longicornis</i>, <i>H</i>. <i>flava</i>, and <i>Ixodes</i> <i>nipponensis</i>) were collected with collection traps. Of the identified ticks, <i>H</i>. <i>longicornis</i> was the most frequently collected ticks (except larval ticks) (94.26%, 8,653/9,180 ticks (nymphs and adults)), followed by <i>H</i>. <i>flava</i> (5.71%, 524/9,180) and <i>Ix</i>. <i>nipponensis</i> (less than 0.04%, 3/9,180). The ticks collected with collecting traps were pooled and assayed for the presence of SFTS virus with negative results. In addition, for monitoring the prevalence of hard ticks, a total of 7,461 ticks (5,529 larvae, 1,272 nymphs, 469 females, and 191 males) of the ixodid ticks comprising 3 species (<i>H</i>. <i>longicornis</i>, <i>H</i>. <i>flava</i>, and <i>Ix</i>. <i>nipponensis</i>) were collected with flagging method. <i>H</i>. <i>longicornis</i> was the highest collected ticks (except larval ticks) (99.53%, 1,908/1,917 ticks (nymphs and adults)), followed by <i>H</i>. <i>flava</i> (1.15%, 22/1,917).

Abstract Dung beetles (coleoptera: geotrupidae) are an extremely important element of many ecosystems. their activity allows the incorporation of mineral compounds trapped in faeces into the nutrient cycle. seasonality and habitat preferences are the most important factors shaping the beetle communities inhabiting dung. the present study compares beetle communities inhabiting moose dung Alces alces L. in various forest ecosystems quantitatively and qualitatively. Due to the beetle seasonality, field work was performed from the beginning of March until the end of october 2017 in three habitats: coniferous forest, oak-hornbeam forest and alder forest. the dung beetles were collected using three Barber traps on each site baited with moose dung (80 g ± 10 g) and the traps were emptied as well as rebaited every 15 days. altogether, 2330 specimen of dung beetles representing three species were collected: Anoplotrupes stercorosus (2088), Trypocopris vernalis (154) and Geotrupes stercorarius (88). these three species were found in all of the studied habitats. the largest total number of individuals was captured in the alder forest (1132 individuals), followed by the broadleaved forest (712) and the smallest number was captured in the coniferous forest (486). in terms of individuals caught, each species was statistically significantly different between the habitats. The largest number of A. stercorosus was captured in the alder forest, followed by the broadleaved forest and the smallest number was caught in the coniferous forest. however, the reverse was observed in the case of T. vernalis and G. stercorarius, where the most individuals were caught in the coniferous forest, and fewer in the broadleaved and alder forests. this is most likely due to the various habitat preferences of each individual species. Furthermore, the seasonal dynamics of this beetle family showed some differences between habitats. these differences most probably resulted from different microclimatic and humidity conditions.
