Abstract:

A century and a half ago, in the European part of Russia (Moscow), forest scientists established the first long-term observations of forests, many of which are under observation to the present day. In the twentieth century, climate changes and, due to industrial development, forest areas were under air pollution. Based on observations from 157 sites, this study shows that the growth and density of Scots pine (Pinus sylvestris L.) have decreased by the end of the twentieth century. The environment has changed, and the growth and development of plantations has slowed. Pine yields (− 34% stand volume) and their life expectancy (on average 50 years) have decreased. These changes are critical for forestry and for the management of forests in urban centers. Due to the decline in growth, ecosystem functions by urban forests has decreased. In order to increase the sustainability of urban forests and the provision of ecosystem services, it is preferable to create multi-species stands with a complex structure.
