The sign in the photo is probably too small in this reproduction to read, but it says that more than 600 beaver would be dropped that year and that 50 had already been dropped in the Chamberlain Basin, northeast of McCall and in the Lochsa-Selway area.
The crates, each containing one 80-100 pound beaver, were dropped in pairs, one male, one female, so that courtship could begin soon after the wooden containers opened on impact. Using cargo chutes, which would later be retrieved by employees hiking into the back country, the beaver boxes were dropped from about 600 feet.
This might seem a silly effort, but it was successful in getting more beavers into areas where they were needed. Yes, needed. Tens of thousands of beavers were taken for their fur in the 19th century, and trapping continues today on a smaller scale. The rodents can change the character of an area faster than anything, save fire. They create terrific habitat for dozens of species.
Beavers rarely fly, the previous example being the exception. They are the largest rodent in North America and the second largest in the world, edged out by South America’s capybara.
"Hata hivyo, ""kiashiria"" katika picha hii ni ndogo sana katika reproduction kusoma, lakini inasema kwamba zaidi ya 600 beavers itakuwa imeshuka mwaka huo na kwamba 50 tayari alikuwa imeshuka katika Chamberlain Basin, kaskazini mashariki ya McCall na katika Lochsa-Selway eneo." Kila sanduku lilikuwa na chombo cha kupigia kura, na kila sanduku lilikuwa na chombo cha kupigia kura, na kila sanduku lilikuwa na chombo cha kupigia kura. Kwa kutumia chutes za mizigo, ambazo baadaye zingechukuliwa na wafanyakazi waliopanda kwenda nyuma ya nchi, masanduku ya beaver yaliangushwa kutoka karibu futi 200. Huenda hilo likaonekana kuwa jambo la kipumbavu, lakini lilifanikiwa kuingiza beavers wengi zaidi katika maeneo ambako walihitajiwa. Ndiyo, ilihitajiwa. Katika karne ya 19, maelfu ya nyangumi waliuawa kwa sababu ya manyoya yao, na leo hii kuna watu wengi wanauawa kwa sababu ya manyoya yao. Wadudu wanaweza kubadilisha tabia ya eneo kwa kasi zaidi kuliko kitu kingine chochote, isipokuwa moto. Wao hufanyiza makao mazuri sana kwa ajili ya spishi nyingi. Nyangumi hawawezi kuruka sana, mfano uliotangulia ni wa kipekee. Wao ndio wanyama wakubwa zaidi wa kuogelea katika Amerika Kaskazini na wa pili kwa ukubwa ulimwenguni, wakishindwa na capybara wa Amerika Kusini.
