We like to think what we're doing is new...
Despite packaging and appearances, nothing we're doing is really new. Some of it might be innovative, but the ideas predate us all. While modern restoration practice chases different fads, and practitioners stumble across techniques new to us, it is easy to convince ourselves we're doing something new and novel. It is important that we learn from history and those before us. We fully acknowledge and appreciate that many practitioners already adopt a cheap and cheerful philosophy in what they do and try to maximize the impact of their actions.
The important thing is that we attempt to learn from the experience of others and take the ideas we like, and incorporate them into our own experiences. We should always be careful to not assume we're the 'first'. Ideas evolve through time as they're past on and 'stolen' and adapted to become our own. As scientists, we have an obligation to make sure we appropriately cite past work. However, as practitioners, the most gratifying thing is to see ideas in others that spawned from seeds you planted, turn into someone else's idea. It is when the ideas grow beyond us to capture the imagination of broader communities that we might stand a chance of addressing the true scope of degradation of our riverscapes. |
The now famous parachuting beaver example...
As beaver restoration became really popular over the past decade, there was a sense in the restoration community that this was a new technique. As the video below highlights, biologists at Idaho Fish & Game in the 1940s had the same idea. The idea was to use beaver to make better trout habitat and reduce damages from floods, by sourcing nuisance beaver that were flooding vacation homes in McCall, Idaho. Sound familiar?

These former paratroopers, now employed as game wardens, had a great idea. How could they reintroduce beaver to areas of the Frank Church Wilderness they had been extirpated from, for cheaper than other relocation efforts of the era (i.e. packing beaver in on mules). They were taking an old idea (at the time) of beaver translocation, and thinking how to make it more efficient.

BDAs in BC In 1930s?If you really want to convince yourself we're not on to anything new when it comes to partnering with beaver as a restoration tool, read Eric Collier's Three Against the Wilderness. Although published in 1959, Eric describes his family's efforts in the 1920s and 1930s to mimic the work of beaver in British Columbia by repairing the abandon dams left behind from their extirpation in his watershed in the 1830s and 1840s. It is one of the earliest examples we know of, of what you might call beaver dam analogues (though he didn't give it a silly acronym). Eventually, he is able to stop doing the maintenance when a game warden brings him a few translocated, live beaver to introduce to the area.
