The lake is the site of a nature reserve, and since 1977 has been designated a UNESCO Biosphere Reserve and a Ramsar site, in view of its importance as a breeding ground for water birds such as grebe, rail, moorhen, grey heron, bearded tit, white-tailed eagle, osprey, rust-coloured kite, cormorant and black tern. The lake is known since many decades as the habitat of the mute swan (Latin: Cygnus olor) – nesting there every year from a dozen to tens of dozen of pairs, and in time of moult arriving in numbers reaching up to 2,000 birds.[2] The lake is part of the larger protected area known as Masurian Landscape Park.^{[citation needed]}

The bottom of the lake is 77% covered with brachiopods (Characeae), potworms (Potamogeton) and spearguns (Myriophyllum). At the banks, there is a strip of reed rush with a small admixture of narrow-leaved cattail and lake bulrush. On the southern and eastern shores, there is a strip of willow thickets and fragments of alders. This creates a favorable shelter for bird nesting and significantly enriches the biotope.[3]
