“…Measures that reduce emissions from deforestation and degradation therefore go hand in hand with other objectives for stabilizing (Gerelbaatar et al 2019a). By reducing canopy cover, intensive logging and fire can trigger the melting of insular permafrost and the release of soil carbon (Juřička et al 2018). Improved control of certain largescale disturbances (e.g.…”

“…On the other hand, forest cover itself plays an important role for the regional hydrology -even more so because the headwater zones of all major river systems are located in forested mountain areas. Forest losses in these regions are therefore likely to have profound impacts on ground and surface water availability (Krasnoshhekov 2001; Kopp et al 2017;Juřička et al 2018). These linkages mean that forest and water management should be considered and implemented in an integrated way.…”

“…Underlying drivers include climate change, which affects the frequency and severity of droughts (Davi et al 2013) and factors related to socioeconomic and political transformation processes in Mongolia (Saladyga et al 2013), which encompass demographic factors, institutional organization, and the political and legal framework (Government of Mongolia 2018). On local scale permafrost degradation can also trigger forest degradation (Juřička et al 2018). All of these aspects need to be understood in order to develop a sustainable forest management framework that can safeguard healthy ecosystem functions and resources, as well as halt or even reverse deforestation and degradation.…”

The natural conditions, climate change and socio-economic challenges related to the transformation from a socialistic society towards a market-driven system make the implementation of sustainable land management practices in Mongolia especially complicated. Forests play an important role in land management. In addition to providing resources and ecosystem functions, Mongolian forests protect against land degradation.GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY 03 (12) 2019

“…Unfortunately, Mongolian forests have been subjected to strong negative impact of illegal timber logging, forest fires and overgrazing for a long time (Tsogtbaatar et al 2004). The combination of anthropogenic disturbance and climate change (Sato et al 2007;Marin 2010;Oyuntuya et al 2015) causes serious change in moisture conditions of the ecosystems leading to deterioration of the forests health (Juřička et al 2018). Weakened Mongolian forests are then exposed extensively to pests (Hauck et al 2008;Dulamsuren et al 2010a).…”

This paper provides information on long-term suppression of natural forest regeneration due to the livestock grazing in the vicinity of one of the world largest open-pit ore mine close the city of Erdenet in Mongolia. The area is characterized by high concentration of herder’s households where the 52% were found only up to 1 km distance from the forest edge. Forest grazing causes extensive damage to seedlings and significant reduction of their growth. Within the 30–99 cm height category, up to 61% Larix sibirica, 90% Betula platyphylla and 68% Populus tremula individuals are grazingdamaged. L. sibirica and P. tremula seedlings with heights over 99 cm were absent, and no individuals of any species were found within 136–200 cm height category. In addition to the seedlings, only 7 or more meters high L. sibirica individuals are found in the forest structure, which means the absence of successfully growing forest regeneration for at least 40 years. In 2017, the defoliation of L. sibirica, reaching locally up to 100%, occurred in the stands east of the mine. Total defoliation represents a high risk of mortality of affected individuals. The stands cannot be successfully regenerated under the conditions of current intensive grazing. Mine metal stocks are calculated to provide for at least another 25 years of mining. Over that time, neither significant population decline nor decreasing grazing pressure on forests can be expected. If effective protection measures are not implemented, there is a risk of transforming threatened forest into steppe.

Measuring climate change impacts on forest ecosystems can be challenging, as many of these changes are imperceptible within the typical time scale of short-term (e.g., 3–4 years) funding of research projects. Boreal trees are notoriously imperturbable, given their tolerance to harsh conditions and their adaptability. However, the buildup of decades of warming should now translate into measurable alterations of boreal ecosystem processes. The boreal forest is host to numerous northern animals; therefore, any change in boreal forest dynamics should affect wildlife. In this chapter, we aim to provide a nonexhaustive synthesis of documented impacts of climate change on selected key processes driving boreal forest ecosystem dynamics. We focus on the themes of plant and wildlife range shifts and stand growth and death, as they are keystone parameters of boreal forest ecosystem health that are symptomatic of climate change impacts on the boreal biota. For each theme, we introduce the general concepts and processes, convey some of the limitations of current assessments, and suggest future pressing challenges.
