V\u011bdci z Cambridgesk\u00e9 univerzity u\u010dinili mimo\u0159\u00e1dn\u00fd objev p\u0159i skenov\u00e1n\u00ed les\u016f Sabahu v Malajsii pomoc\u00ed LiDAR skeneru. Skener detekoval obrovsk\u00fd strom, kter\u00fd se ty\u010dil nad okoln\u00ed vegetac\u00ed. P\u0159i bli\u017e\u0161\u00edm zkoum\u00e1n\u00ed potvrdili, \u017ee se jedn\u00e1 o 89,5 metru vysok\u00fd ohro\u017een\u00fd \u017elut\u00fd meranti (Shorea faguetiana). Tento objev vytvo\u0159il nov\u00fd sv\u011btov\u00fd rekord pro nejvy\u0161\u0161\u00ed tropick\u00fd strom a p\u0159ekonal tak p\u0159edchoz\u00edho dr\u017eitele rekordu, 88,3 metru vysok\u00fd \u017elut\u00fd meranti v nedalek\u00e9m n\u00e1rodn\u00edm parku Tawau Hills.<\/p>\n\n
Aby p\u0159esn\u011b zm\u011b\u0159il v\u00fd\u0161ku stromu, vystoupal na jeho vrchol m\u00edstn\u00ed expert na lezen\u00ed po stromech Unding Jami s p\u00e1smem. B\u011bhem sv\u00e9ho v\u00fdstupu v\u0161ak narazil na ne\u010dekan\u00e9 v\u00fdzvy. “Nem\u011bl jsem \u010das fotit dobr\u00fdm fo\u0165\u00e1kem, proto\u017ee v okol\u00ed krou\u017eil orel, kter\u00fd m\u011b neust\u00e1le napadal, a tak\u00e9 l\u00e9talo spousta v\u010del,” uvedl Jami. P\u0159es tyto p\u0159ek\u00e1\u017eky se mu poda\u0159ilo ur\u010dit v\u00fd\u0161ku stromu.<\/p>\n\n
Objev tohoto ob\u0159\u00edho stromu je z\u00e1bleskem nad\u011bje pro ochranu tropick\u00fdch les\u016f. Ukazuje, \u017ee tyto lesy, p\u0159esto\u017ee \u010del\u00ed \u010detn\u00fdm hrozb\u00e1m, st\u00e1le skr\u00fdvaj\u00ed potenci\u00e1l pro pozoruhodn\u00e9 objevy. Nav\u00edc impozantn\u00ed v\u00fd\u0161ka stromu zpochyb\u0148uje dlouho tradovanou v\u00edru, \u017ee tropick\u00e9 stromy nemohou dos\u00e1hnout stejn\u00fdch v\u00fd\u0161ek jako stromy m\u00edrn\u00e9ho p\u00e1sma.<\/p>\n\n
Zat\u00edmco stromy m\u00edrn\u00e9ho p\u00e1sma, jako jsou ob\u0159\u00ed sekvoje, mohou r\u016fst a\u017e o 30 metr\u016f v\u00fd\u0161e ne\u017e tropick\u00e9 stromy, v\u011bdci jsou touto rozd\u00edlnost\u00ed st\u00e1le zmateni. Hlavn\u00ed v\u00fdzkumn\u00edk David Coomes vysv\u011btluje: “Nikdo nev\u00ed, pro\u010d by tomu tak m\u011blo b\u00fdt.” Je t\u0159eba prov\u00e9st dal\u0161\u00ed v\u00fdzkum, abychom odhalili environment\u00e1ln\u00ed faktory, kter\u00e9 omezuj\u00ed v\u00fd\u0161ku tropick\u00fdch strom\u016f.<\/p>\n\n
Ob\u0159\u00ed stromy nejsou jen \u00fachvatn\u00fdmi p\u0159\u00edrodn\u00edmi divy, ale hraj\u00ed tak\u00e9 z\u00e1sadn\u00ed roli ve zdrav\u00ed a ekologii les\u016f. Poskytuj\u00ed \u00fato\u010di\u0161t\u011b \u010detn\u00fdm druh\u016fm, p\u0159isp\u00edvaj\u00ed k ob\u011bhu \u017eivin a pom\u00e1haj\u00ed regulovat klima. Coomes zd\u016fraz\u0148uje: “Ochrana t\u011bchto obr\u016f je opravdu d\u016fle\u017eit\u00e1. N\u011bkter\u00e9, jako jsou kalifornsk\u00e9 sekvoje, pat\u0159\u00ed k nejv\u011bt\u0161\u00edm a nejd\u00e9le \u017eij\u00edc\u00edm organism\u016fm na Zemi.”<\/p>\n\n
Sn\u00edmkov\u00e1n\u00ed LiDAR se uk\u00e1zalo b\u00fdt neoceniteln\u00fdm n\u00e1strojem pro identifikaci a posuzov\u00e1n\u00ed zdegradovan\u00fdch les\u016f po cel\u00e9m sv\u011bt\u011b. Analyzov\u00e1n\u00edm dat shrom\u00e1\u017ed\u011bn\u00fdch LiDAR skenery mohou v\u011bdci lokalizovat a m\u011b\u0159it velk\u00e9 stromy, sledovat zdrav\u00ed les\u016f a identifikovat oblasti pro potenci\u00e1ln\u00ed obnovu. Coomes zd\u016fraz\u0148uje: “LiDAR n\u00e1m m\u016f\u017ee pomoci identifikovat a posoudit 2,5 miliardy akr\u016f zdegradovan\u00fdch les\u016f po cel\u00e9m sv\u011bt\u011b, kter\u00e9 by se potenci\u00e1ln\u011b daly obnovit.”<\/p>\n\n
Na rozd\u00edl od les\u016f m\u00edrn\u00e9ho p\u00e1sma, kter\u00e9 pot\u0159ebuj\u00ed stalet\u00ed, aby dos\u00e1hly stavu star\u00e9ho porostu, se tropick\u00e9 lesy mohou \u010dasto vzpamatovat z nadm\u011brn\u00e9 t\u011b\u017eby a st\u00e1t se zral\u00fdmi ekosyst\u00e9my b\u011bhem 50 a\u017e 100 let. Tato odolnost d\u00e1v\u00e1 nad\u011bji na obnovu zdegradovan\u00fdch les\u016f. Coomes v\u0161ak varuje: “To ned\u00e1v\u00e1 t\u011b\u017ea\u0159\u016fm carte blanche k tomu, aby k\u00e1cely velk\u00e9, zral\u00e9 stromy, jejich\u017e regenerace trv\u00e1 d\u00e9le.”<\/p>\n\n
