Ekološke i florističke karakteristike novog nalazišta maklena (Acer monspessulanum L.) na lokalitetu Glogovita kosa na Boranji

Abstract

U radu je opisano novo nalazište maklena (Acer monspessulanum L.) na planini Boranji, u GJ "Istočna Boranja", iznad Roguljskog potoka, na grebenu Glogovita kosa. Maklen se pojavljuje na nadmorskoj visini od 460 do 480 m, na jugozapadnoj i zapadnoj ekspoziciji, na vrletnom nagibu od 45° do 50°. Površina nalazišta je 874 m2 , a koordinate centra nalazišta su: l=19°13'49,0" i ph=44°25'21,33". Na navedenom nalazištu maklen se pojavljuje u zajednici crnog graba i crnog jasena, a s obzirom da je zabeležen u sva tri sprata, a u spratu žbunja i prizemne flore pojavljuje se obilno, izdvojena je subasocijacija sa maklenom (Ostryo carpinifoliae-Fraxinetum orni subass. aceretosum monspessulanii). Po florističkom sastavu većina biljnih vrsta pripadaju submediteranskom flornom elementu, stoga ova zajednica predstavlja enklavu submediteranske vegetacije u pojasu kontinentalnih šuma bukve. Zajednica je azonalnog karaktera, uslovljena je orografsko-edafski, pojavljuje se na toplim ekspozicijama, na plitkoj i skeletnoj rendzini na oolitskim krečnjacima.

A new motpellier maple (Acer monspessulanum L.) site was described in this paper, located on mountain Boranja, in forest management unit "Istočna Boranja", above Roguljski potok, on Glogovita kosa ridge. Montpellier maple occurs on elevations between 460 and 480 m a.s.l., on southwestern and western aspect, on very steep slopes with inclination 45° to 50°. The site area is 874 m2 , and coordinates of site centre are: l=19°13'49.0" and ph=44°25'21.33". In this site, Montpellier maple occurs in a plant community of hop-hornbeam and manna ash, and considering that Montpellier maple was recorded in all three layers, and that it occurs abundantly in shrub and ground layers, a subassotiation with montpellier maple was set apart (Ostryo carpinifoliae-Fraxinetum orni subass. aceretosum monspessulanii). According to floristic composition, most plant species belong to the submediterranean floral type, so this community represents an enclave of submediterranean vegetation in the belt of continental beech forests. The community is of azonal character, orographically-edaphically conditioned, and occurs in warmer aspects, on shallow and skeletal rendzina on oolithic limestones.
