In this study, floristic and ecological characteristics of Orthotricho straminei-Pterigynandretum
filiformis wich was determined from two different regions of Turkey (Marmara
and Black Sea) were compared according to the regions in Turkey. Relevés were
taken from different tree species in different habitats in these regions.
The floristic composition of Orthotricho straminei-Pterigynandretum filiformis which
was determined using the Braun-Blanquet method and the ecological characteristics of
the taxa within the association such as humidity, light, acidity, tree preference and habitat
tendencies were compared.
As a result of the study, it was determined that the floristic composition of the association
varies depending on the region and habitats where it is distributed. And also, it
was determined that ecological requirements of the taxa belonging to the association
differed according to the characteristics of epiphytic habitat, especially humidity and
tree preference.
