The present paper describes the current situation of yews in the Cisowy Jar Reserve: number, their state of health, height and diameter structure, and the sex ratio. In the result only 25 yews were found. Their state of health was relatively good, but many yews that grew on very heavily shaded stands were characterized by little height accretion and greater leaf reduction than those growing on more sunny positions. There is no continuity of population. No specimens in the height range between 51-100 cm were found. Sparse seedlings die in first years after appearing. Active human help is necessary to protect and to reconstruct the yew population in the reserve.
