Among the PNA where biotechnical events are held are :  "Zarafshan" National Nature Park, "Aktag-Tamdi" State Reserve, "Sudochye-Akpetki" State Reserve, Zaamin State Reserve, Surkhan State Reserve, Lower-Amudarya State Biosphere Reserve, Barsakelmes State Reserve, "Yukori Tupalang" National Nature Park, and others. 

In hard-to-reach places of these territories, employees of PNA lay out food products such as salt, coarse hay, and bran for animals.

For information: biotechnical events are held annually in winter at all wholesale enterprises of the country. The food left by the staff helps the animals survive during severe cold weather and simplifies their search for food.
