I'll give it more thought. In the meantime, I'll refrain from engaging in biodiversity policies and regulatory conversations referring to such things. Consider my contribution to that subject matter as superficial and cursory. However and notwithstanding that, I also suggest you take great care when infringing on the freedoms and liberties of others, even despite their ignorance.
As long as I have your ear, here's an interesting dynamic interplay of nature that is interesting. Please take a moment to digest this, as I think you will find it interesting, given the fact that I do believe you are intelligent. The first paragraph is some history, and the second is about some science.
First, in the interest of business (ranching and land development), the following megafauna exterminations (among others) occurred in the nineteenth and twentieth centuries in the US: Between 1850 and 1900, two million wolves were poisoned, shot or trapped. In 1880, the Gray Wolf was gone from the Great Plains. By 1920, the Texas Gray Wolf and Mexican Gray Wolf were exterminated. in 1926, the Great Plains Lobo Wolf, in 1940 the Southern Rocky Mountains Wolf, and in 1950 the Cascade Mountains Brown Wolf.
Now, onto the concept of trophic cascades. Ripple and Beschta (paper cited below) have shown that wolves increase and/or preserve biodiversity. How? Riparian environments are the areas on both sides of a creek or stream. Herbivore populations (i.e elk, etc.), in the absence of predation, will browse everywhere. But when wolves are present, they will not browse in areas where their escape routes are hindered, such as near cliffs or creeks. By not browsing in such areas, various and diverse vegetation is allowed to flourish, which in turn provides an environment for further organisms. This in turn has an effect on downstream water quality, which furthers the cascading effect.

Wolves, elk, willows, and trophic cascades in the upper Gallatin Range of Southwestern Montana, USAThe point here, is the way nature self regulates, and the necessity of enforcing policy to allow it to do so. This requires knowledge, which cannot be counted upon to be possessed by every self interested land or business owner.
