Epiphytic bryophytes and vegetation of the east Spruce in the Orumcek forest.

Abstract

The Picea orientalis in the Orumcek forests are the tallest with the largest-diameter found in Turkey, Europe, and Caucasica. In this study, the vegetation and the epiphytic bryophytes of the Spruce in the Orumcek forests were investigated. Bryophyte specimens collecting from the Spruce tree trunks were evaluated and 26 bryophtes taxa (6 liverworts, 20 mosses) belonging to 17 families and 19 genera were identified. As a result of the evaluation of the releves taken from the Spruce trunks with the Braun-Blanquet method, the Dicrano scoparii - Hypnetum cupressiformis association and -sanionietosum uncinatae subassociation belonging to the Dicrano scoparii - Hypnion cupressiformis alliance was determined as being new to Turkey. The life forms and life strategies of the syntaxa were examined and analyzed in terms of the ecological and floristic values. Mat (Ma) and Cushion (Cu) are dominant in the association, Weft (We) is dominant in the subassociation of the life forms while, perennial styers with a high sexual reproductive effort (Ag) was determined as being dominant in both the association and subassociation. The most taxa of the floristic list were are also determimed as mesophytic, sciophyt, and subneutrophyt as a character.
