Last month in a post entitled Making the Case for Saving Species, I reviewed an article written by Emma Marris about doing all we can to prevent species from going extinct, even when the approach is not a popular one – like introducing rust resistant genes into native whitebark pine populations. Intrigued by Marris’ words, I decided to finally read her book, Rambunctious Garden: Saving Nature in a Post-Wild Word, which had been sitting on my bookshelf for several months and had been on my list of books to read for at least a couple of years before that. At only 171 pages, Marris’ book is a quick read and comes across as an introduction to some sort of revolution. Its brevity demands future volumes, which are hopefully on their way.
The general topic that Marris addresses is how to do conservation work in a world that is riddled with human fingerprints, especially coming from a perspective that human influence is and has been largely negative. What should our goals be? The traditional approach has been to restore natural areas to a historical baseline. In North America, that baseline is usually pre-European colonization. So, we remove introduced species and we use whatever records we have and data we can gather to make natural areas look and function as they did several hundred years ago.
But there are some concerns with this approach. Rewinding time requires massive amounts of money, labor, and time, and if that historical baseline is ever achieved, it will require great effort to keep it there. Also, a number of species have gone extinct and there is no way of replacing them (unless we introduce similar species as proxies), and some species require large areas to roam that even our most spacious parks cannot accommodate. And then there is the challenge of continual change. Anthropogenic climate change aside (which complicates conservation and restoration efforts in serious ways), the earth’s ecosystems are in a constant state of flux, so holding a site to a pre-determined baseline makes little sense when viewed from a geological timescale.
There is another issue – which is in part a semantic one – and that is, we seem to have a distorted view of nature. We like to think of it as being apart from us, away from us, somewhere wild and pristine. Marris writes: “We imagine a place, somewhere distant, wild and free, a place with no people and no roads and no fences and no power lines, untouched by humanity’s great grubby hands, unchanging except for the season’s turn. This dream of pristine wilderness haunts us. It blinds us.”
We are blinded because “pristine” is a myth. Every inch of the globe has been altered in some way by humans – some areas more than others – and disconnecting ourselves from nature in a way that makes it unattainable deters us from the perception that nature can be all around us. Nature is not found only in national parks, nature preserves, and other protected areas, but in our backyards, on our rooftops, along roadsides, in the cracks of concrete, and in farm fields. Nature is everywhere. And if nature is everywhere, then conservation can happen everywhere.
After a brief overview of how we (Americans specifically) arrived at our current approach to conservation and restoration, Marris dives into some new approaches, visiting sites around the world and talking with biologists and ecologists about their work. She explores rewilding (Pleistocene rewilding even), assisted migration, embracing exotic species, novel ecosystems, and designer ecosystems. The subject matter of each chapter in Marris’ book is worthy of a post or two of its own, but I’ll spare you that and suggest that you read the book. The controversy that surrounds these novel approaches is also worth noting. A few searches and clicks on the internet will lead you to some fairly heated debates about the ideas that Marris puts forth in her book, as well as some criticisms of Marris herself.

My view as an outsider – that is, one without a high level degree in ecology and lacking years of experience working in the field – is that the tools and methods outlined in Marris’ book are worth exploring further. Certainly, each natural area must be approached differently depending on the conditions of the site and the goals of the managers. [Marris offers a great overview of some goals to consider in her last chapter.] Ultimately it is up to people much smarter and more experienced than I to sort it all out. But I heartily encourage thinking outside of the box…for whatever it’s worth.
And that brings me to what I loved most about the book. Controversy aside, Marris’ clarion call for a paradigm shift is a welcome one. Nature is all around us, and regardless of what land managers and the powers that be decide to do with large tracts of land “out there,” every individual can find purpose and beauty in the nature that surrounds them, whether it be the street trees that line our neighborhoods or the vacant lot growing wild with weeds down the street. We can decide to let our yards go a little feral, to plant some native plants, to encourage wildlife in urban areas, and to even do a little assisted migration of our own by planting things from nearby regions just to see how they will do in our changing climate. In short, we can garden a bit more rambunctiously. And we should.
This is how Marris puts it:
If we fight to preserve only things that look like pristine wilderness, such as those places currently enclosed in national parks and similar refuges, our best efforts can only retard their destruction and delay the day we lose. If we fight to preserve and enhance nature as we have newly defined it, as the living background to human lives, we may be able to win. We may be able to grow nature larger than it currently is. This will not only require a change in our values but a change in our very aesthetics, as we learn to accept both nature that looks a little more lived-in than we are used to and working spaces that look a little more wild than we are used to.
