POPULATION DYNAMICS OF LIPARIS LOESELII (L.) L. C. RICH. IN THE NATURE RESERVE ‘MIELNO’ – SOME RESULTS FROM A 8 YEAR STUDY

Leszek Bednorz

 

ABSTRACT



This paper presents some results of a 8 year (1995-2002) observation of Liparis loeselii population in the nature reserve ‘Mielno’. The total population numbers as well as generative and vegetative ones differ from year to year. The population grew from 73 in 1995 to 106 in 1997, falling to 29 in 2002. At the same time unfavourable changes in population environment (progressive drainage of the area and expansion of woody plants) have been observed.

Key words: Liparis loeselii, population dynamics, microhabitat, nature reserve ‘Mielno’..
