The present study conducted in the Dallol Bosso fossil valley aims to know the local perception of the level of threat on the Neocarya macrophylla species in order to provide indicators of sustainable management of the natural stand. To do this, surveys were conducted in two agro-ecological zones.The collection of information was carried out through a simple questionnaire based on the woody stand, the sources of supply and the part of the plant taken from the woody food species, as well as the threats they suffer and their causes. It appears that the most dominant species is Neocarya macrophylla ; a multipurpose species among others, used for food, medicine and wood.The survey also reveals the presence of twenty four (24) ligneous foods species among which eighteen (18) are common to both zones. Analyses showed, the excessive cutting of the wood and the unfavorable climatic conditions as the main factors resulting on potential threat of these species. At the same time, threats on Neocarya macrophylla, a characteristic species of Dallol Bosso valley were identified on the field.

The research aimed at verifi cation of fungi species colonizing phyllosphere of pontic azalea <em>Azalea pontica </em>L. and at comparison of the fungi species composition: – in the natural stand in the Kołacznia nature reserve, – in arboretum collections at Bolestraszyce and Rogów. 600 fragments of healthy, infected and fallen leaves of pontic azalea were collected for mycological analyses. The species forming the largest number of colonies identified from the healthy leaves were: <em>A. alternata</em>, <em>Ph. cyclaminis</em>, <em>E. nigrum</em>, <em>Ph. medicaginis </em>and <em>B. cinerea, </em>from infected leaves<em>: A. alternata</em>, <em>E. nigrum, Ph. cyclaminis</em>, <em>S. fi micola</em>, <em>T. viride </em>and <em>A. phaeospermum, </em>whereas: <em>E. nigrum</em>, <em>A. alternata</em>, <em>S. fi micola</em>, <em>Ph. cyclaminis and B. cinerea </em>were isolated from the fallen leaves, which indicates that a majority of fungi persistently colonize the leaves during vegetation period and damage them, which leads to defoliation. Colonization of pontic azalea phyllosphere in arboreta by more numerous fungi colonies and species than under conditions of natural sites evidences their increased pressure in the arboreta environment.
