Astravy Dulieby, Hydrological reserve in Bialyničy District, Belarus

Astravy Dulieby is a 26,600-hectare hydrological reserve in the Bialyničy and Kličaŭ Districts of Mahilioŭ Region, Belarus. Forests cover 76% of its area, including pine, birch and black alder, while raised and transitional bogs such as the Duliebskaje and Vialikaje bogs take up 11%. Two lakes lie within the reserve: Podozierishcha at 21.4 hectares and Druchanskaje at 1.9 hectares.

The reserve was created by a Council of Ministers resolution (No. 947 of 17 June 1998) to protect a bog massif and valuable forest that feed the sources of the Dolzhanka, Dulebka, Terebol, Rozhanka and Vodonoska rivers. On 21 November 2024 the republican hydrological reserve was reorganised into the republican reserve Astravy Dulieby.

Since 1998 the reserve has hosted the annual eco-art festival "Astravy Dulieby" in Kličaŭ, promoting sustainable development, rational use of natural resources and revival of local historical and cultural heritage. The reserve's marshes feed the rivers Dolžanka, Dulebka, Terebol, Rožanka and Vodonoska, a role reflected in local place names.

Several walking paths cross the reserve, allowing visitors to explore the landscape and observe birds and wildlife. Wear appropriate clothing for wet conditions and bring insect protection to make your visit more comfortable.

The reserve's marshes feed the headwaters of five rivers — the Dolzhanaka, Dulebka, Terebol, Rozhanka and Vodonoska — which is why it was protected as a hydrological zakaznik. Its two lakes are Podozerishche, 21.4 hectares, and Druchanskoye, 1.9 hectares. Since 21 November 2024 it has been a general republican zakaznik rather than a hydrological one.
