Na konci 18. a na po\u010d\u00e1tku 19. stolet\u00ed p\u0159ivezli lovci ko\u017ee\u0161in na Aleutsk\u00e9 ostrovy li\u0161ky. Tyto li\u0161ky se \u017eivily vejci a ml\u00e1\u010faty husy aleutsk\u00e9, co\u017e vedlo k prudk\u00e9mu poklesu jejich populace. V roce 1940 byl tento druh prohl\u00e1\u0161en za vyhynul\u00fd.<\/p>\n\n
V roce 1962 se Bob “Mo\u0159sk\u00e1 vydra” Jones vydal na odv\u00e1\u017enou v\u00fdpravu na ostrov Buldir, odlehlou z\u00e1kladnu na Aleut\u00e1ch. P\u0159es zr\u00e1dn\u00e9 podm\u00ednky Jones hledal jak\u00e9koli zn\u00e1mky ztracen\u00fdch hus. Jeho vytrvalost se vyplatila, kdy\u017e spat\u0159il hejno hus aleutsk\u00fdch let\u00edc\u00edch na z\u00e1pad.<\/p>\n\n
Jones\u016fv objev vzbudil nad\u011bji, kterou v\u0161ak tlumily pochybnosti. Husi mohly pat\u0159it k jin\u00e9mu druhu. Nezdoln\u00fd Jones soust\u0159edil sv\u00e9 p\u00e1tr\u00e1n\u00ed na ostrov Buldir, proto\u017ee v\u011b\u0159il, \u017ee by mohl b\u00fdt \u00fato\u010di\u0161t\u011bm hus.<\/p>\n\n
Kdy\u017e se Jones p\u0159ibl\u00ed\u017eil k ostrovu Buldir, p\u0159iv\u00edtal ho prosperuj\u00edc\u00ed ekosyst\u00e9m pln\u00fd \u017eivota, v\u010detn\u011b mo\u0159sk\u00fdch vyder, papuchalk\u016f, alkoun\u016f a lachtan\u016f. Narazil na zemi nedot\u010denou lovci ani li\u0161kami.<\/p>\n\n
Na vysok\u00fdch mo\u0159sk\u00fdch \u00fatesech Jones kone\u010dn\u011b spat\u0159il svou odm\u011bnu: 56 hus aleutsk\u00fdch. Zvuk jejich vrzav\u00e9ho kejh\u00e1n\u00ed, kter\u00fd lid\u00e9 nesly\u0161eli po cel\u00e1 desetilet\u00ed, naplnil vzduch. Jones\u016fv objev vydl\u00e1\u017edil cestu k zotaven\u00ed tohoto druhu.<\/p>\n\n
Husa aleutsk\u00e1 se stala jedn\u00edm z prvn\u00edch \u017eivo\u010dich\u016f prohl\u00e1\u0161en\u00fdch za ohro\u017een\u00fd druh. Jones shrom\u00e1\u017edil husata k rozmno\u017eov\u00e1n\u00ed v zajet\u00ed a pokra\u010doval v odstra\u0148ov\u00e1n\u00ed li\u0161ek z dal\u0161\u00edch ostrov\u016f. D\u00edky jeho \u00fasil\u00ed byly li\u0161ky vyhubeny z ostrova Amchitka a vytvo\u0159ily tak pro husy bezpe\u010dn\u00e9 \u00fato\u010di\u0161t\u011b.<\/p>\n\n
Biologov\u00e9 vy\u0161kolen\u00ed Jonesem znovu vysadili husy na Amchitku a dal\u0161\u00edch z\u00e1padn\u00edch ostrovech. Zpo\u010d\u00e1tku husy bojovaly, ale jejich po\u010det se postupn\u011b zvy\u0161oval. Z n\u011bkolika stovek vzrostl na tis\u00edce a stal se d\u016fkazem s\u00edly ochrany.<\/p>\n\n
Dnes prosperuj\u00ed na ostrovech bez li\u0161ek desetitis\u00edce hus aleutsk\u00fdch. Tento druh byl v roce 2001 vy\u0161krtnut ze seznamu ohro\u017een\u00fdch druh\u016f, co\u017e znamenalo v\u00fdznamn\u00e9 v\u00edt\u011bzstv\u00ed ochrany.<\/p>\n\n

Tak\u00e9 podtrhuje potenci\u00e1l \u00fasp\u011bchu ochrany, kdy\u017e se tyto prvky spoj\u00ed.<\/p>\n\n
