An Investigation of Spatial Pattern in WychElm (Ulmus glabra)
in-Hyrcanian Forest, Case Study: Kheyroudkenar Forest,
Noshahr.
Abstract
The current research on wych elm was performed in Kheyroudkenar Forest, Noshahr. To detect the
spatial pattern, Mean Square method was employed. Initially the locations of Wych elm individuals
were recorded through GPS equipment, then transferred into Computer.For the design of grids with
different sizes as weir as Markingpoints on them.Arcview, Arcinfo and Idrisi softwares were applied.
Theresults indicated that Wych elm exhibits a pattern intermediate between random and clumped.
This is the existing.pattern of Ulmus glabra, because probably its real.pattern has been changed due to
Dutch elm disease as well as due to illegal cuttings.
