Abstract:Ruševec se na Pohorju (severno-vzhodna Slovenija) pojavlja na grebenskih legahv zahodnem delu pogorja. V rastitvenih sezonah 2000 in 2001 smo napravilipopis aktivnosti sub-populacij na šestih znanih rastiščih in tako izločili ploskve potencialnega habitata. Na njih smo raziskovali odločilne vegetacijske strukture. V primerjavo sta vključeni tudi dve opuščeni rastišči.Vse popisne ploskve (400x400m) so bile razdeljene na 256 osnovnih ploskvic. Ugotavljamo, da so štiri aktivna rastišča. med seboj relativno homogena, od njih pa se jasno ločita obe opuščeni rastišči. Razlike med srednjimi vrednostmi ocenjevanih značilnosti vegetacijskih tipov (pokrovnost borovnice, brusnice, jesenske vrese, zeliščne plasti, delež travišč in traviščv zaraščanju, grmovne plasti, sklep krošenj smreke in jerebike v drevesni plasti ter mravljišč) so statistično značilne. Trend upadanja abundance ocenjevanih značilnosti habitata je opazen od zahoda do opuščenih rastišč na vzhodu, od zaledja stabilne alpske populacije proti robu ob subpanonskem fitogeografskem območju. Pokrovnost borovnice na aktivnih rastiščih je 19%, na opuščenih 5%, pokrovnost zeliščne plasti ocenjevanih vrstje 38%, na opuščenih 11%, število mravljišč je 13,7/ha, na opuščenih rastiščih 8/ha. Primerjava med vegetacijskimi tipi je pokazala, da so najprimernejši habitati na mestih, kjer se prepletajo barjanski ekosistemi (12%), travišča (15%), zaraščajoča travišča (41 %), gozd (31 %) in vodne površine (1 %), vendar ob pogoju, da območje ni v nadaljnjem zaraščanju in ni preveč obljudeno.

Title:Vegetation requirements of the black grouse habitat (Tetrao Tetrix L.) in Pohorje MTS.
Abstract:The Black Grouse inhabits mountain ridges in the western part of the Pohorje Mts (1543 m a.s.l., NE Slovenia). In the mating periods (2000, 2001), we carried out a survey of six known pairing areas and thus separated plots of potential habitat. In comparison, two abandoned display grounds were also incorporated. The base sampling areas (400 x 400 m) were divided into 256 square planes. It was discovered that the four active display grounds were relatively homogenous, while the two abandoned grounds clearly differed from them. The differences of the observed vegetation type characteristics (cover of blueberry, cranberry, autumn heather, herb layer, share of pastures including those now being overgrown, the abundance of bush layer, crown density of Norway spruce, mountain ash and anthills) are statistically significant. This declining tendency was noticeable from the display grounds in the west to the abandoned display grounds in the east, from the hinterland of a stable Alpine population towards the edge of the sub-Pannonian phytogeographic region. Cover value of blueberry on active display grounds is 19%, abandoned display grounds 5 %, herb layer 38% (11%), the number of anthills is 13.7/ha (8/ha). A comparison between vegetation types and richness of herbal and shrub layer has shown that the most suitable habitats for the Black Grouse are places with interchanging swampland ecosystems (12%),pastures (15%), partially overgrown pastures (41%), forest (31%) and water areas (1%), although on preliminary condition that the area is not beingfurther overgrown and overpopulated, by human.
