Zvisikwa(Avian):Greater White-fronted Goose (Anser albifrons), Tundra Bean Goose (Anser serrirostris)
Abstract:
Kumabvazuva kweAsia shiri dzemvura dzinotama dzakadzikira zvakanyanya kubva kuma1950, kunyanya huwandu hwevanhu vanogara muchando muChina. Kuchengetedza kunokanganiswa zvakanyanya nekushaikwa kweruzivo rwekutanga nezvemafambiro ekufambisa uye nzvimbo dzekumira. Chidzidzo ichi chinoshandisa matekiniki ekuronda setiraiti uye ongororo yenzvimbo yepamusoro yekuongorora mafambiro echirimo yehanzi hombe rine chena-kumberi (Anser albifrons) uye tundra bean goose (Anser serrirostris) munguva yechando pedyo nerwizi rweYangtze Floodplain. Zvichienderana nemateki makumi maviri nemana akawanikwa kubva kuvanhu makumi maviri nemumwe muchirimo cha2015 na2016, takaona kuti Northeast China Plain ndiyo iri kure-kure nzvimbo yekumisikidza inonyanya kushandiswa panguva yekutama, uye gezi dzinogara kweinodarika mwedzi mumwe. Iyi dunhu zvakare yakagadziridzwa zvakanyanya zvekurima, zvichipa chikonzero chechikonzero chekudzikira kwechando chekuEast Asia shiri dzemvura muChina. Kudzivirirwa kwemvura inoshandiswa senzvimbo yekugara, kunyanya iyo yakakomberedzwa nevhu rekudya zvakanyanya, kwakakosha kuti shiri dzemumvura dzirarame. Pamusoro pe90% yenzvimbo yakakosha inoshandiswa panguva yekutama kwechirimo haina kuchengetedzwa. Tinokurudzira kuti ongororo dzepasi dzinofanirwa kunanga nzvimbo idzi kuratidza kukosha kwadzo kune shiri dzemvura dzinotama pahuwandu hwevanhu, uye nzvimbo yekugara munzvimbo dzakakosha dzematsutso dzinofanira kubatanidzwa mumambure enzvimbo dzakachengetedzwa munzira inobhururuka. Pamusoro pazvo, shiri-kunetsana kwevanhu munharaunda yepakati kunoda kuongororwa. Chidzidzo chedu chinoratidza kuti kuronda satellite pamwe chete nekuongorora kwenzvimbo kunogona sei kupa ruzivo rwakakosha kuvandudza kuchengetedzwa kwezvipenyu zvinodzikira.
