\u201eKlimatick\u00e1 zmena v\u00fdrazne men\u00ed podmienky v slovensk\u00fdch lesoch. Jednou z najohrozenej\u0161\u00edch drev\u00edn je smrek oby\u010dajn\u00fd, ktor\u00fd v minulosti tvoril rozsiahle monokult\u00fary najm\u00e4 v ni\u017e\u0161\u00edch poloh\u00e1ch,\u201c vysvetlila SAV.<\/p>\n

V\u00fdskum sa pod\u013ea vedcov opiera o tzv. provenien\u010dn\u00e9 pokusy, \u010di\u017ee experimenty, v ktor\u00fdch vedci porovn\u00e1vaj\u00fa r\u00f4zne popul\u00e1cie tej istej dreviny poch\u00e1dzaj\u00face z r\u00f4znych geografick\u00fdch oblast\u00ed. Cie\u013eom je zisti\u0165, ktor\u00e9 z nich s\u00fa najodolnej\u0161ie vo\u010di meniacim sa klimatick\u00fdm podmienkam. \u201eNeznamen\u00e1 to, \u017ee by sme mali smrek z na\u0161ich lesov \u00faplne odstr\u00e1ni\u0165. Sk\u00f4r h\u013ead\u00e1me popul\u00e1cie, ktor\u00e9 maj\u00fa prirodzen\u00fa schopnos\u0165 lep\u0161ie sa prisp\u00f4sobi\u0165 teplu a suchu, a mus\u00ed sa, samozrejme, zmeni\u0165 aj druhov\u00e1 a vekov\u00e1 kompoz\u00edcia t\u00fdchto porastov,\u201c uviedla Gabriela Jamnick\u00e1 z \u00dastavu ekol\u00f3gie lesa SAV.<\/p>\n

Smrek sa v minulosti vys\u00e1dzal aj do oblast\u00ed, kde pre\u0148 neboli ide\u00e1lne podmienky. V ni\u017e\u0161\u00edch nadmorsk\u00fdch v\u00fd\u0161kach dnes \u010del\u00ed kombin\u00e1cii stresov\u00fdch faktorov, a to dlhodob\u00e9mu suchu, vysok\u00fdm teplot\u00e1m a premno\u017eeniu lyko\u017er\u00fata, tvrdia odborn\u00edci. Pr\u00edkladom s\u00fa kalamity v oblastiach stredn\u00e9ho Slovenska, napr\u00edklad v okol\u00ed \u010cierneho Balogu. Vedci preto sk\u00famaj\u00fa, ako jednotliv\u00e9 popul\u00e1cie smreka reaguj\u00fa na stresov\u00e9 podmienky.
