-  maintaining  the  composition  of  air  in  the 
atmosphere (oxygen production, absorption of 
excess CO
2
); 
-  climate-forming function;  
-  water  protection  and  water-regulating 
functions (water regulation of lakes, rivers and 
other water bodies, ensuring protection of river 
banks,  hydrologic  behavior  of  watersheds, 
etc.); 
-  protection  of  soils  from  water,  wind  erosion 
and other types of degradation;  
-  recreational functions;  
-  sanitary and hygienic functions;  
-  aesthetic functions;  
-  preservation  of  unique  natural  complexes 
(Kiryushin, 2021).  
Some of these functions can be used as ecosystem 
services,  provided  an  adequate  market  is  created. 
According  to  this  condition,  the  following  4 
categories  of  ecosystem  services  are  defined  as  the 
most promising:  
-  regulation  of  water  resources,  air  quality, 
climate, erosion prevention; 
-  biodiversity  conservation  services 
(preservation of unique ecosystems, plant and 
animal species, genetic diversity); 
-  preservation  and  use  of  the  values  of  the 
aesthetic and cultural view of landscapes; 
-  carbon sequestration.  
The  latest  ecosystem  service  has  a  solid  global 
market.  
The functions of natural forests are more or less 
inherent  in  forest plantations, especially large tracts 
of  restored  and  planted  forests, although to  a  lesser 
extent  this  concerns  biodiversity.  In  cities,  towns, 
recreation areas, the influence of forest plantations on 
reducing the level of air pollution with dust and gases, 
reducing  noise  levels,  wind  speed  is  particularly 
increasing,  the  sanitary  role  of  phytocenoses  is 
actively  manifested  here.  The  problem  of 
afforestation  is  becoming  more  widespread, 
especially  in  Western  Europe,  while  in  Africa  the 
problem of reducing tropical forests does not lose its 
relevance.  
The report of the UN Conference on Environment 
and  Development  in  1992  focused  on  the  need  to 
expand the area of forest cover through reforestation 
and  artificial  planting  of  trees  and  forests  on 
unproductive  lands  affected  by  degradation  and 
deforestation.  In  recent  years,  this  task  has  been 
motivated  by  the  need  to  reduce  CO
2
  in  the 
atmosphere and curb global warming. To this end, it 
is  planned  to  double  the  forest  area  of  Ukraine, 
Poland,  the  Czech  Republic,  Germany  and  France 
through forest plantations on treeless lands.  
In  this regard,  the  danger of afforestation of the 
preserved  virgin  areas of  the steppe  gives  cause  for 
concern.  Many  environmentalists  rightly  insist  on 
excluding them from afforestation plans. As for mass 
afforestation in the steppe zone, especially in the dry 
steppe, its possibilities are limited by forest-growing 
conditions  characterized  by  additional  surface  or 
ground  moisture.  These  are  sections  of  the 
hydrological  network,  ravine-beam  complex,  etc 
(Kiryushin, 2021).  On upland lands, the creation of 
forests  is  an  extremely  complex  and  difficult  task 
associated  with  the  contradictions  of  the  aborigine 
and  the  newcomer.  The  fall  of  sod  grasses  forms 
steppe mat, which contributes to the wet deposition, 
which is used by them more effectively than by wood 
ones.  As  a  result,  woody  vegetation  on  watershed 
areas covered with steppe turf falls out quickly. This 
is  the  difference  between  steppe  ecosystems  and 
ravine and floodplain forests, confined to moistened 
and  shaded  relief  depressions  and  river  valleys. 
Steppe cereals cannot exist for a long time under the 
closed  canopy  of  a  deciduous  forest.  In  the  forest 
plantations  of  the  steppe  zone,  trees  are  in  sharply 
unfavorable  environmental  conditions,  so  they  are 
almost  always  weakened  and  are  characterized  by 
increased vulnerability to pests and diseases. Because 
of these reasons, the canopy does not form or quickly 
falls apart.  There  is  a gradual return of  sod  cereals, 
followed  by  rapid  degradation  of  forest  plantations 
and,  eventually,  the  restoration  of  the  steppe 
ecosystem (Vasilyuk, 2002).  
Forest  management  and  its  sustainability  today 
represent  a  rather  acute  and  controversial  problem. 
The  definition  of  the  sustainability  of  forest 
management  was  given  in  1995  in  the  draft 
declaration  of  the  Ministerial  Conference  on  the 
Protection  of  Forests  held  in  Helsinki,  which  is  the 
management of forests and their areas, as well as their 
use,  contributing  to  their  biological  diversity, 
productivity, the ability to renew, as well as the ability 
in  the  present  and  in  the  future  to  perform  various 
functions of social, environmental, economic nature 
without  negative  impact  on  other  ecosystems  at 
different levels (local, national and global).  
In  the  Russian  Federation,  according  to  various 
estimates, the forest  cover  of the  land  reaches  from 
about 48% to 51%, which is significantly higher than 
the  global  average of 27%,  which  was  70%  in  pre-
agricultural time. Today, the use  of  the  potential  of 
Russian forests is characterized by low efficiency. In 
Russia, with its approximately 1/4 of all world forest 
resources,  world  forest  products  account  for  only 
about  3%,  less  than  25%  in  general,  the  size
