A thought experiment in the Highlands

Much ink has been spilled over the merits and flaws of rewilding. It is a concept which I have come out in support of multiple times before, though I take issue with many of the claims and arguments made by some so-called "rewilders". One of the main points of disagreement between advocates and opponents of rewilding has been as to what impacts simply letting nature reassert itself would have. Some people say that it would be negative, that human activities are necessary for the preservation of our ecosystems, while others say that it is unquestionably a positive, that can only serve to better our wildlife. Both of these positions are of course extremes, and most people lie somewhere in between, but they give a  general idea of what the sides are. To actually answer the question is a difficult if not impossible task, as it would depend on a wide variety of factors. Whether reintroductions are considered a necessary part of rewilding, for instance, completely changes what results said process would have. In this post, I will indulge in a thought experiment of sorts, centered on the British highlands: What if all farming along with most other human activity everywhere in the uplands was stopped, and deer numbers were heavily culled and kept at bay. No reintroductions, no direct action aside from the culling, just a complete ceasing of all activities in the highlands. I do not actually advocate this scenario, nor do I find it remotely plausible, but it offers some idea of what the outcome of one extreme form of rewilding would be. As we will eventually see, it also shows why reintroductions are in fact necessary for rewilding and habitat restoration in the long term, and that "grazing bad, trees good" is not always true.

For All To See: Overgrazing apologists and regressive conservation

I have talked about the British highlands before, discussing its depleted state, and how it came to be this way. In that article I also devoted a substantial quantity of words to how conservationists have, for a long time, been helping preserve this depleted landscape. None of this has radically changed in the few months since I wrote that post, nor is the subject of today any more relevant now than it was then. It is also not any less relevant however. What I will be talking about here is the issue of those conservationists who have not moved on, who still cling to the old and outdated notions of what is and is not good for nature. They are unfortunately still large in number, and often fill some of the most powerful positions in conservation, controlling the majority of nature reserves. Change is coming, but as with all upheavals, there will be resistance, and much of it at that. Still, there is something uncannily disturbing about a conservationist, supposedly bolstered and driven by science, trumpeting blatantly and demonstrably false statements, so heavily contradicted by evidence, much of which they must be aware of, to border on outright lying. This post is both a rebuttal to the arguments made by these people, and also a reflection on just why they are acting the way they are, and how we may perhaps be able to change it in time.

The world that we forgot

Humans are an inherently short sighted species. We do not think too far into the future, and rarely gaze much further back than our youth. At most, the average person thinks a few decades forward, and a century back, anything beyond that is largely forgotten, or ignored. For conservationists protecting nature, this cone of vision is slightly less narrow, often looking an entire century forward, and sometimes upwards of 500 years back. This allows them to view the general trends these last few centuries have experienced. But it is still a narrow view, and still does not offer one crucial thing; Perspective. Most conservation efforts focus either on preserving areas as they are today, or turning them back at most a few hundred years. Often the time just before the industrial revolution is used as a target, an ideal. In this post I will discuss why to properly conserve nature, one must look much further back, and how this lack of perspective and vision is choking nature today.
