“…These management practices—favoring organic layer decay—are performed with different considerations for the impact they generate on both atmospheric and aquatic CO 2 and CH 4 fluxes. The most extensive studies have been conducted in Finland 14 , 47 , 48 , while in Canada the C sequestration function of peat soils and carbon accounting are still rarely taken into account in forested peatland management 49 , 50 . Yet, the value of organic horizons for C sequestration highlighted in the present study suggests that the loss of carbon from peat layer disturbance or removal cannot be offset within a short-term period (e.g., 200 years) by enhanced tree growth.…”

Peatlands are significant carbon (C) stores, playing a key role in nature-based climate change mitigation. While the effectiveness of non-forested peatlands as C reservoirs is increasingly recognized, the C sequestration function of forested peatlands remains poorly documented, despite their widespread distribution. Here, we evaluate the C sequestration potential of pristine boreal forested peatlands over both recent and millennial timescales. C stock estimates reveal that most of the carbon stored in these ecosystems is found in organic horizons (22.6–66.0 kg m−2), whereas tree C mass (2.8–5.7 kg m−2) decreases with thickening peat. For the first time, we compare the boreal C storage capacities of peat layers and tree biomass on the same timescale, showing that organic horizons (11.0–12.6 kg m−2) can store more carbon than tree aboveground and belowground biomass (2.8–5.7 kg m−2) even over a short time period (last 200 years). We also show that forested peatlands have similar recent rates of C accumulation to boreal non-forested peatlands but lower long-term rates, suggesting higher decay and more important peat layer combustion during fire events. Our findings highlight the significance of forested peatlands for C sequestration and suggest that greater consideration should be given to peat C stores in national greenhouse gas inventories and conservation policies.

“…As known, steppe ecological conditions (dry climate and lack of moisture), as well as technogenesis environmental conditions (anthropogenic activities, pollution of air and soil) negatively effect on the trees life. However, the dendrometric parameters of forest park stands (stem density, stem height, stem diameter, stand volume, stand basal area) in Background ecological areas were similar to the natural forest (Lafleur et al, 2018;Kuuluvainen and Gauthier, 2018). This phenomenon can only be explained by the location of some parks.…”

The present study examines the relationships between structure (floristic composition, dendrometric parameters), diversity (diversity and evenness indexes) of urban forest park stands and the ecological (soil fertility, soil moisture), environmental factors (air pollution). The study is based on the forest park stands inventory data, performed from 2012 to 2017 in Kryvyi Rih City, Central Ukraine. The floristic compositions of the urban forest park stands are poor. There are only 23 species that belong to 14 families and 12 genera. More families were represented by at least more than 2% of taxon diversity. While Ulmaceae (2 genera, 4 species-17,39 %), Fabaceae (3 genera, 2 species-17,39 %), Aсеrасеае (1 genera, 4 species-17,39 %) were the most representative families. It was established that at forest park the values of stand density varied from 490 to 660 trees*ha-1 , stem heights were from 26 to 31 m, stem diameters were from 13 to 17 cm, stand basal area were from 32 to 49 m 2 *ha-1 , stand volume were from 200 to 415 m 3 *ha-1. the values of relative stem heights were from 0,63 to 0,82 m*year-1 , relative stem diameters were from 0,31 to 0,43 cm*year-1 , relative stand basal area were from 0,80 to 1,19 m 2 *ha-1 *year-1 , relative stand volume were from 5,45 to 10,28 m 3 *ha-1 *year-1. The varied values of the forest park stands index (Shannon-Wiener diversity index from 0,75 to 1,61, Pielou"s evenness index from 0,53 to 0,86, Simpson"s diversity from 0,24 to 0,60, Margalef"s diversity index from 0,87 to 6,97) indicate the ecological instability of these woody plant communities. Current state of the urban forest park stands determined by the combined influence of ecological (soil fertility, soil moisture) and environmental factors (air pollution).

“…Such forest management of the highly paludified areas would not require any practices that lead to soil disturbing (i.e., field preparation), and therefore could enhance soil organic carbon storage. Indeed, from a climate change perspective, one of the advantages of the use of management solutions with no or little soil disturbance (i.e., partial and selection cuts) is that they would have a positive effect on the amount of carbon stored in the soil OL (i.e., soil carbon stocks) in paludified forest soil [35]. From management implications perspective, the results of this study are important for landscape management for several reasons: (i) we have demonstrated the potential of LiDAR data to provide spatially detailed topographic information that can be used as sources of data in managing, planning and optimization of forest management activities in paludified boreal forests;…”

The accumulation of organic material on top of the mineral soil over time (a process called paludification) is common in Northern Boreal coniferous forests. This natural process leads to a marked decrease in forest productivity overtime. Topography both at the surface of the forest floor (i.e., above ground) and the subsurface (i.e., top of mineral soil which is underground) is known to play a critical role in the paludification process. Until recently, the availability of more accurate topographic information regarding the surface and subsurface was a limiting factor for land management and modeling of spatial organic layer thickness (OLT) variability, a proxy for paludification. However so far, no research has assessed which of these two topographic variables has the greatest influence on paludification. This study aims to assess which topographic variable (surface or subsurface) better explains paludification, using high-resolution remote sensing technology (i.e., Light Detection and Ranging: LiDAR and Ground Penetrating Radar: GPR). To this end, field soil measurements were made in over 1614 sites distributed throughout the reference Valrennes Experimental site in Canadian northern coniferous forests. Then, a machine learning model (i.e., Random Forest, RF) was implemented to rank a set of selected predictor topographic variables (i.e., slope, aspect, mean curvature, plan curvature, profile curvature, and topographic wetness index) using the Mean Decrease Gini (MDG) index as an indicator of importance. Results showed that overall 83% of the overall variance was explained by the RF selected model, while the derived subsurface topography predictors had the lowest MDGs for predicting paludification. On the other hand, the surface slope predictor had the highest MDGs and better explained paludification. This finding would be particularly useful for implanting sustainable management strategies based on the surface variables of paludified northern boreal forests. This study has also highlighted the potential of LiDAR data to provide surface topographic spatial detail information for planning and optimizing forest management activities in paludified boreal forests. This is even of great importance when we know that LiDAR variables are easier to obtain compared to GPR derived variables (subsurface topographic variables).
