Exploiting the nature

Men exploit nature, but at the same time he renews it and regulates that exploitation. In that manner planned afforestation is carried out and new forest plantations arise.

In certain times of the year its prohibited to hunt and fish certain animal species. Creating new arable land (deforestation,drainage of wetlands, etc.) has led to creation of new biocenosis, which we can split into three types:

• Agrarian biocenosis
  Agrarian biocenosis occur by cultivating natural areas. Some of them are arable land, pastures, gardens, orchards and vegetable gardens. On arable lands, for example,only one species of plants is being cultivated ( monoculture ).
  
  That type of biocenosis must constantly be processed which requires a lot of material resources. It is necessary to constantly combat pests and diseases that cause a lot of damage to agricultural production. Maintenance of agrarian biocenosis is only possible under human control.

• Horticultural plant communities
  We find these communities in cities. They are communities of cultivated and ornamental plants in gardens and parks. They heavily depend on human care.
  

• Ruderal biocenosis
  Ruderal biocenosis occur if agrarian biocenosis aren't taken care of. They are communities incurred on abandoned and untreated soil, close to settlements, roads, railways and dumpsites.
