Beaver trappers moved the beavers in a more conventional manner in that case, but it's clear that—by land or by air—the beavers could help Idaho just as much as Idaho could help the beavers.The cost of building a dam wasn't the only money involved in the beaver-moving project. Popular Mechanics ran a 1949 feature on the parachuting Idaho beavers, which also mentions that the trappers working with the effort were able to keep some of the animals for themselves, to sell their fur coats. At a time when the beaver population was estimated at 90,000 in Idaho, beaver trappers were allowed to only skin a few for their own profit, and then took care of the rest of the beaver population in designated areas.”</span> </a>由 <a href="https://www.behance.net/pj4"><span style="font-size: 12px;color:black;">Paul Engel</span></a> 授权许可 <span><a href="https://creativecommons.org/licenses/by-nc-nd/4.0/deed.zh" target="_blank" style="font-size: 12px;color:black;">Attribution-NoDerivs-NonCommercial 4.0 International<img src="" style="display: inline-block;height: 16px;width: auto;"></a></span></p>
