Cambridge \u00dcniversitesi’nden ara\u015ft\u0131rmac\u0131lar, Malezya’n\u0131n Sabah ormanlar\u0131n\u0131 bir LiDAR taray\u0131c\u0131s\u0131 kullanarak tararken ola\u011fan\u00fcst\u00fc bir ke\u015fifte bulundular. Taray\u0131c\u0131, \u00e7evresindeki bitki \u00f6rt\u00fcs\u00fcn\u00fcn \u00fczerinde y\u00fckselen devasa bir a\u011fa\u00e7 tespit etti. Daha detayl\u0131 bir inceleme sonras\u0131nda, bunun nesli t\u00fckenmekte olan, 293,6 fit y\u00fcksekli\u011finde sar\u0131 meranti a\u011fac\u0131 (Shorea faguetiana) oldu\u011funu do\u011frulad\u0131lar. Bu ke\u015fif, 88,3 metrelik yak\u0131nlardaki Tawau Hills Ulusal Park\u0131’ndaki sar\u0131 merantiyi geride b\u0131rakarak, d\u00fcnyan\u0131n en uzun tropik a\u011fac\u0131 i\u00e7in yeni bir d\u00fcnya rekoru k\u0131rd\u0131.<\/p>\n\n
A\u011fac\u0131n y\u00fcksekli\u011fini do\u011fru bir \u015fekilde \u00f6l\u00e7mek i\u00e7in, yerel a\u011fa\u00e7 t\u0131rmanma uzman\u0131 Unding Jami, bir mezura ile a\u011fac\u0131n tepesine t\u0131rmand\u0131. Ancak t\u0131rman\u0131\u015f\u0131 s\u0131ras\u0131nda beklenmedik zorluklarla kar\u015f\u0131la\u015ft\u0131. Jami, “\u0130yi bir foto\u011fraf makinesi kullanarak foto\u011fraf \u00e7ekecek vaktim yok \u00e7\u00fcnk\u00fc etrafta s\u00fcrekli bana sald\u0131rmaya \u00e7al\u0131\u015fan bir kartal var ve ayr\u0131ca etrafta \u00e7ok say\u0131da ar\u0131 u\u00e7uyor,” diye bildirdi. Bu engellere ra\u011fmen, a\u011fac\u0131n y\u00fcksekli\u011fini ba\u015far\u0131yla belirledi.<\/p>\n\n
Bu dev a\u011fac\u0131n ke\u015ffi, tropik ormanlar\u0131n korunmas\u0131 i\u00e7in bir umut \u0131\u015f\u0131\u011f\u0131d\u0131r. Bu ke\u015fif, bu ormanlar\u0131n, say\u0131s\u0131z tehdit alt\u0131nda olmalar\u0131na ra\u011fmen, hala kayda de\u011fer ke\u015fifler yapma potansiyeline sahip oldu\u011funu g\u00f6stermektedir. Dahas\u0131, a\u011fac\u0131n etkileyici y\u00fcksekli\u011fi, tropik a\u011fa\u00e7lar\u0131n \u0131l\u0131man a\u011fa\u00e7lar kadar y\u00fcksek olamayaca\u011f\u0131 y\u00f6n\u00fcndeki uzun s\u00fcredir devam eden inanca meydan okumaktad\u0131r.<\/p>\n\n
Dev sekoyalar gibi \u0131l\u0131man a\u011fa\u00e7lar, tropik a\u011fa\u00e7lardan 30 metreye kadar daha uzun boylu olabilseler de, bilim insanlar\u0131 bu farkl\u0131l\u0131k kar\u015f\u0131s\u0131nda hala \u015fa\u015fk\u0131nl\u0131k i\u00e7indedir. Ba\u015f ara\u015ft\u0131rmac\u0131 David Coomes, “Bunun neden b\u00f6yle olmas\u0131 gerekti\u011fini kimse bilmiyor,” diye a\u00e7\u0131kl\u0131yor. Tropik a\u011fa\u00e7lar\u0131n y\u00fcksekli\u011fini s\u0131n\u0131rlayan \u00e7evresel fakt\u00f6rleri ortaya \u00e7\u0131karmak i\u00e7in daha fazla ara\u015ft\u0131rmaya ihtiya\u00e7 vard\u0131r.<\/p>\n\n
Dev a\u011fa\u00e7lar yaln\u0131zca ilham verici do\u011fal harikalar de\u011fil, ayn\u0131 zamanda ormanlar\u0131n sa\u011fl\u0131\u011f\u0131 ve ekolojisinde de hayati bir rol oynamaktad\u0131r. \u00c7ok say\u0131da t\u00fcre ya\u015fam alan\u0131 sa\u011flarlar, besin d\u00f6ng\u00fcs\u00fcne katk\u0131da bulunurlar ve iklimi d\u00fczenlemeye yard\u0131mc\u0131 olurlar. Coomes, “Bu devleri korumak ger\u00e7ekten \u00f6nemli. Baz\u0131lar\u0131, Kaliforniya’daki sekoyalar gibi, d\u00fcnyadaki en b\u00fcy\u00fck ve en uzun \u00f6m\u00fcrl\u00fc organizmalar aras\u0131ndad\u0131r,” diye vurguluyor.<\/p>\n\n

LiDAR taray\u0131c\u0131lar\u0131 taraf\u0131ndan toplanan verileri analiz ederek ara\u015ft\u0131rmac\u0131lar b\u00fcy\u00fck a\u011fa\u00e7lar\u0131 bulabilir ve \u00f6l\u00e7ebilir, orman sa\u011fl\u0131\u011f\u0131n\u0131 izleyebilir ve potansiyel restorasyon alanlar\u0131n\u0131 belirleyebilirler. Coomes, “LiDAR, potansiyel olarak restore edilebilecek, d\u00fcnya \u00e7ap\u0131ndaki 2,5 milyar d\u00f6n\u00fcml\u00fck bozulmu\u015f orman\u0131 belirlememize ve de\u011ferlendirmemize yard\u0131mc\u0131 olabilir,” diye vurguluyor.<\/p>\n\n
Il\u0131man ormanlar\u0131n eski orman stat\u00fcs\u00fcne ula\u015fmas\u0131 y\u00fczy\u0131llar al\u0131rken, tropik ormanlar genellikle a\u015f\u0131r\u0131 kerestecilikten kurtulabilir ve 50 ila 100 y\u0131l i\u00e7inde olgun ekosistemler haline gelebilirler. Bu dayan\u0131kl\u0131l\u0131k, bozulmu\u015f ormanlar\u0131n restorasyonu i\u00e7in umut vermektedir. Ancak Coomes uyar\u0131yor, “Bu, kerestecilere yenilenmesi daha uzun s\u00fcren b\u00fcy\u00fck, olgun a\u011fa\u00e7lar\u0131 kesmeleri i\u00e7in izin vermiyor.”<\/p>\n\n
