I was chairman of the "They Otter be in Iowa" program back in the 1980's and we sold T-shirts and sweatshirts that said "they otter be in Iowa" to raise money. We were successful in releasing many otters in conjunction with the DNR. I forget the numbers, but I think there were just under 100 released at about a dozen sites. We traded turkeys to Louisiana for the otters, which were trapped on the bayous and transported to Iowa.
I was a director of the Iowa Trapper's Assn at the time and we never dreamed they would do as well as they have, but we wanted to do it for the positive publicity it would give trappers at a time when we were battling antis on every front. It was hugely successful. I was able to stand at a podium at several release sites with hundreds of people watching including busload after busload of school kids and TV cameras rolling, and tell them how trappers and hunters care about wildlife and all that. It definitely was a shining moment for outdoorsmen and a real coup over the antis in Iowa. At the time, we were battling ridiculous snaring regulations and anti-trapping regulations in the legislature, and the positive PR we got was huge in defeating the anti legislation. Plus I spent a lot of hours lobbying in Des Moines. We got a tremendous amount of positive PR over the otter reintroductions in newspapers, TV and radios. Even the Des Moines register treated us kindly (what a shock), although they never did get over calling it "ironic" that otters were being stocked by trappers when we would likely never be able to trap them.
That was 15 years ago. Now they are doing very well and it's entirely possible that we may actually see a limited trapping season on them in the future. They are a fascinating animal and I'm proud to have been a leader in the reintroduction efforts.
