I-Australia ilwela ukusindisa izinhlobo zopholi ezisengozini yokushabalala

I-golden-bellied upholi (Neophema chrysogaster) isengozini enkulu. Inani labantu endle lifinyelele emashumini amane! Ekuthunjweni, kukhona abangaba ngu-300 babo, abanye babo basezindaweni ezikhethekile zokuzalanisa izinyoni, ebezisebenza kusukela ngo-1986 ngaphansi kohlelo lwe-Orange-Bellied Parrot Recovery Team.

Izizathu zokuncipha okuqinile kwenani labantu balolu hlobo alukho nje kuphela ekucekeleni phansi kwendawo ezihlala kuzo, kodwa futhi ekwandeni kwezinhlobo ezahlukene zezinyoni nezilwane ezidla inyama, ngokungeniswa kwazo ngabantu kuleli zwekazi. “Izakhamuzi ezintsha” zase-Australia zaba yizimbangi eziqine kakhulu zopholi abane-golden-bellied.

Izazi zezinyoni ziyazi ukuthi isikhathi sokuzalanisa kwalezi zinyoni kusehlobo engxenyeni eseningizimu-ntshonalanga yeTasmania. Ngenxa yalokhu, izinyoni zifuduka minyaka yonke zisuka emazweni aseningizimu-mpumalanga: eNew South Wales naseVictoria.

Ukuhlola okwenziwa ososayensi e-Australian National University kwakuhlanganisa ukubeka amatshwele achanyuselwe ekukhanyeni phakathi kopholi ezidlekeni zopholi basendle bezinsikazi ezinesisu esibomvu phakathi nenkathi yokuzalanisa izinyoni.

Kwakugcizelelwa iminyaka yamatshwele: kusukela ezinsukwini ezi-1 kuye kweziyi-5 ngemva kokuchanyuselwa. UDokotela uDejan Stojanovic (Dejan Stojanovic) wabeka amatshwele amahlanu esidlekeni sensikazi yasendle, ezinsukwini ezimbalwa amane awo ashona, kodwa elesihlanu lasinda futhi laqala ukukhuluphala. Ngokusho kososayensi, owesifazane unakekela kahle "isisekelo". UStojanovic unethemba futhi ubona lo mphumela muhle kakhulu.

Iqembu kwadingeka lithathe isinyathelo esinjalo ngemva kwemizamo eminingana engaphumelelanga yokucwilisa opholi abafuywe abavalelwe endaweni yabo yemvelo. Izinga lokusinda laliphansi kakhulu, izinyoni zazingenwa izifo ezihlukahlukene kakhulu.

Futhi, abacwaningi bazama ukushintsha amaqanda angavundisiwe esidlekeni sopholi basendle abanesisu segolide bafake avundisiwe avela lapho azalela khona.

Ngeshwa, kusukela ekuqaleni kukaJanuwari, ukutheleleka kwamagciwane esikhungweni saseHobart kuqede izinyoni eziyi-136. Ngenxa yalokho okwenzekile, esikhathini esizayo, kuzothathwa izinyathelo zokusabalalisa izinyoni ezikhungweni ezine ezihlukene, ezizoqinisekisa ngokumelene nenhlekelele enjalo esikhathini esizayo.

Ukuqubuka kokutheleleka ngebhaktheriya esikhungweni sokuzalela kuphoqe ukumiswa kokuhlolwa ngesikhathi ukuhlukaniswa kanye nokuphela kokwelashwa kwazo zonke izinyoni ezihlala lapho okwamanje.

Naphezu kwale nhlekelele, ithimba lososayensi likholelwa ukuthi lolu cwaningo lwaba yimpumelelo naphezu kweqiniso lokuthi kwasetshenziswa isidleke esisodwa kuphela kwezintathu ezikhethiwe. Izazi zezinyoni zilindele ukuhlangana nengane yokutholwa ngesizini ezayo, umphumela omuhle uzovumela indlela yokufisa kakhulu yokuhlola.
