Ukwehla kwengxenye yemvelo yomhlaba kunomthelela omubi esimweni sezimbali nezilwane. Namuhla, isimo esingesihle sendawo yokuhlala emanzini nokukhula kwezinhlobo ezahlukahlukene kunomthelela ekuqothulweni kwempilo yasemanzini. Izinhlobo ezingavamile zisongelwa ngokuqothulwa futhi zidinga ukuvikelwa.
IRed Book ngumbhalo okhuluma ngezinhlobo zezilwane ezidinga usizo nokuvikelwa. Ukubamba nokucekela phansi lezi zinhlobo kujeziswa ngumthetho. Lokhu kuvame ukuba yinhlawulo enkulu yemali. Kepha kungenzeka ukuthwala icala lobugebengu ngokuboshwa.
Wonke ama-taxa asengozini, kufaka phakathi inhlanzi, angamalungu wesigaba esisodwa kwezihlanu. Ukuba ngezigaba kunquma izinga losongo enhlotsheni ethile. Izinga lokuvikelwa nezindlela zokubuyiselwa kwemithombo yemvelo, okufanele kuthinte ukukhula kwenani labantu bezinhlobo ezingavamile, kuya ngomklomelo wesigaba.
Isigaba sokuqala sifaka izinhlobo zezinhlanzi ezisengozini yokuqothulwa. Lezi yizimo ezinengozi ebucayi. Isigaba esilandelayo sifaka izinhlobo zezilwane ezinyamalala ngokushesha. Isigaba sesithathu izinhlobo ezingavamile ezingaba sengozini. Owesine uhlanganisa izinhlobo ezingafundwanga kahle. Lesi sakamuva siphakamisa ukuthi i-taxa ibuyisiwe kepha isavikelwe.

Isiphetho
Amazwe ayengaphansi kwe-USSR anomthombo omkhulu wemvelo nemibandela yokuthuthukiswa kwezilwane zasendle. Inani le-taxa liyashintsha, ngakho-ke amaRed Data Books ahlala ekhishwa kabusha ngemuva kokungezwa nokuvuselelwa. Yonke idatha ihlolwe ngokucophelela futhi ihlolisiswe ngochwepheshe ngaphambi kokungena emakhasini eRed Book.
Ukuvikelwa kwempilo yasemanzini kubaluleke kakhulu njengokuvikelwa kwama-amphibians, izitshalo, izilwane ezincelisayo. Ngokuphazamisa imvelo yasemanzini, siphazamisa uhlelo lwemvelo lulonke. Ukuba khona kweRed Book kusisiza ukuthi silawule izinhlobo zezilwane ezisengozini futhi kubuyise inani labantu.
Ukunakekela iplanethi kungumsebenzi obaluleke kakhulu esintwini. Isimo semvelo yamanzi nezindawo eziseduzane namanzi siya ngokuya siba sibi ngenxa yokugxambukela okungapheli endaweni abahlala kuyo abantu. Asikwazi ukukuvimba lokhu, kepha singasiza izinhlobo ezisengozini yokuphela zisinde.
Ukuvela kweRed Data Book kuvunyelwe ukuthi kubhekwe i-taxa edinga ukuvikelwa futhi ibenze bavikeleke. Izindawo zamazwe ethu zicebile ezindaweni eziyingqayizivele lapho izinhlobo eziningi zenziwe zaziwa khona. Umthelela omubi kulezi zindawo unciphisa inani labamele umhlaba wasemanzini, futhi uma kungenziwanga lutho, amaningi awo azonyamalala kungabonakali.
