Z\u00e1sadn\u00fd je pritom pr\u00edstup k dostato\u010dn\u00e9mu mno\u017estvu a kvalite z\u00e1vlahovej vody.

Ak by neboli tieto rozvojov\u00e9 opatrenia zav\u010dasu vykonan\u00e9, ur\u010dite by sme aj po ekonomickej str\u00e1nke poc\u00edtili z\u00e1\u0165a\u017e spojen\u00fa so spotrebou komer\u010dne z\u00edskavanej \u00fa\u017eitkovej vody,\u201c pribl\u00ed\u017eil Gregorek.<\/p>\n

Z rastl\u00edn, ktor\u00e9 najviac tr\u00e1pi aktu\u00e1lne po\u010dasie, spomenul vresoviskov\u00e9 druhy, ako napr\u00edklad azalky, rododendrony, ale aj zn\u00e1me \u010du\u010doriedky. \u201ePre ne s\u00fa vysok\u00e9 teploty, spojen\u00e9 s premenlivou vlhkos\u0165ou, siln\u00e9 odparovanie a zaso\u013eovanie substr\u00e1tu ve\u013emi neprirodzen\u00e9.

Pr\u00edli\u0161 vysok\u00e9 teploty nesved\u010dia dokonca ani teplomiln\u00fdm rastlin\u00e1m, tak\u017ee aj pri intenz\u00edvnom zalievan\u00ed nemus\u00ed by\u0165 v\u00fdkonnos\u0165 veget\u00e1cie na najvy\u0161\u0161ej \u00farovni. \u201eNemal\u00e1 \u010das\u0165 z\u00e1vlahovej vody sa spotrebuje na ochladzovanie. Intenz\u00edvne odparovanie hor\u00fa\u010davu aspo\u0148 \u010diasto\u010dne zni\u017euje,\u201c dodal Gregorek.<\/p>\n

Jedn\u00fdm z najv\u00e1\u017enej\u0161\u00edch d\u00f4sledkov neobvyklej kl\u00edmy je pod\u013ea neho aj zhor\u0161uj\u00faci sa stav drev\u00edn. V\u0161ade, kde nie je mo\u017en\u00e9 zabezpe\u010di\u0165 prilep\u0161enie v\u00fddatnou z\u00e1vlahou, zn\u00e1\u0161aj\u00fa stromy siln\u00fa z\u00e1\u0165a\u017e. Dreviny s\u00fa v d\u00f4sledku extr\u00e9mnych tepl\u00f4t a nedostatku p\u00f4dnej aj ovzdu\u0161nej vlahy ove\u013ea viac druhotne atakovan\u00e9 \u0161kodcami, r\u00f4znymi patog\u00e9nmi a tr\u00e1pen\u00e9 aj fyziologick\u00fdmi poruchami.<\/p>\n

\u201eNedostatok vlahy v p\u00f4de neumo\u017e\u0148uje rastlin\u00e1m v potrebnej miere nahr\u00e1dza\u0165 straty tekut\u00edn sp\u00f4soben\u00e9 odparovan\u00edm, ale popritom netreba zab\u00fada\u0165, \u017ee zo zahusten\u00e9ho p\u00f4dneho roztoku nedok\u00e1\u017ee veget\u00e1cia z\u00edskava\u0165 potrebn\u00e9 \u017eiviny,\u201c upozornil Gregorek.<\/p>\n

Od toho, ako sa podar\u00ed uchr\u00e1ni\u0165 krajinu pred \u010fal\u0161\u00edm vysu\u0161ovan\u00edm, bude pod\u013ea neho z\u00e1visie\u0165 aj v\u00fdsledok boja s klimatickou zmenou. D\u00f4sledn\u00e1 ochrana a zabezpe\u010dovanie zdrojov vody je existen\u010dne d\u00f4le\u017eit\u00e1. \u201eM\u00e1me presved\u010div\u00fa sk\u00fasenos\u0165 s t\u00fdm, ako v\u00fdrazne sa aj v podmienkach botanickej z\u00e1hrady v poslednom \u010dase spotreba z\u00e1vlahovej vody zvy\u0161uje. Ve\u013ekorys\u00e9 zavla\u017eovanie je z\u00e1kladnou podmienkou na udr\u017eanie cel\u00e9ho ekosyst\u00e9mu v dobrej kond\u00edcii,\u201c dodal.<\/p>\n
