When I actually get around to updating this blog I have going here, I typically spend my time talking about specific biological phenomena, or species, that go relatively underappreciated by the non-biologist public. After all, the name of this project is Shit You Didn’t Know About Biology, is it not? However, as someone with a background in evolutionary biology, as well as ecology, I can attest to the significance of communities of organisms and large scale patterning over landscapes. Our planet can be broken up into distinct ‘bioregions’ or ‘ecoregions’, which contain geographically distinct groups of communities of species, and these regions tend to be unique to other defined regions. Think of them as neighborhoods of sorts, each one defined by a specific combination of factors from local geology, geography, climate, and recent biogeography (or, the local distribution of organisms in that region; for example, you aren’t going to find tigers in the grasslands of Brazil, or sloths in the jungles of Central Africa, since a combination of evolutionary history, lineage migration, and plate tectonics has influenced the biogeography of these critters). The one I’ve chosen to talk about sits in an isolated and generally unfamiliar corner of the United States. This bioregion is very dear to me, because I spent more than three years of my life living there in high school, and although I was not there long, I was continually impressed by how special of a location it is. It is known as the Klamath Mountains ecoregion, as those mountains are a dominant feature in the region; the region, more generally, is also referred to as the Klamath Uplift, the Klamath Knot, and the Klamath-Siskiyou area. From a historical and political perspective, the region is effectively the coastal two-thirds of the proposed U.S. state of ‘Jefferson’, which straddles the current border between Oregon and California.
The map above shows some formal boundaries of designated ecoregions in the Pacific Northwest, and 78 is generally accepted as the Klamath Mountains zone. I’ve circled a slightly differently oriented area in red as to show the areas with which I’m most familiar, and additionally, because the presence of the Klamath Uplift itself influences the climate and resulting biodiversity of coastal zones (zone 1 on the map), so that the coasts of far southern Oregon and far northern California are very different from rest of the coastlines from their respective states. In blue, where the Klamath ecoregion, and its associated uplands, come closest to the Pacific, is where I went to high school; Brookings, OR. The 150 sq miles surrounding this small town, down the coast and inland, are unique even within this special ecoregion due to this close juxtaposition of these ecological entities. I feel as though this region needs some devoted attention not only because of its one-of-a-kind attributes, but because it is an almost undiscovered place. This is true of both outsiders to the Northwest (or as I like to call them, the Those That are Seriously Missing Out), as well as people that have lived in the Northwest, even within Oregon, their entire lives. Part of the reason for this is because this area is sparsely populated; the nearest large cities, like Portland and San Francisco, are hundreds of miles north and south, along narrow, ill-maintained, rain-beaten coastal roads. Simply getting there is an arduous endeavor that involves transversing harsh, forested terrain, cutting through largely uninhabited river canyons, and putt-putting down Hwy 101 on the coast, trying not to drive off a cliff in the face of Biblical-style rainstorms with violent winds. It is largely because of this lack of habitation that this area has remained so pristine and the unique biodiversity has kept intact. The coastline does attract a modest seasonal tourist population every year, because the area has a more amiable climate than areas north and south of there, and the natural beauty of the place is unparalleled and untainted by the suffocation of human influence. It is this natural beauty and ever-present access to undistilled wilderness that many that I knew that grew up there to say ‘yeah, I guess it’s pretty special.’ But this doesn’t go far enough. The Klamath ecoregion is more than special for being pretty to live, work, and recreate in. This region of the world has among one of the highest levels of species endemism on the Pacific Coast; species endemism refers to species that are found in only one, distinct geographic area and that area only, often evolved to conditions in that special little micro-range. By this definition, it is exceptionally unique, ecologically, and this distinction, I believe, is more impactful than aesthetics.
Due to its warmer climate, which has more in common with California than Oregon and the rest of the Pacific Northwest, it has been described as a ‘chunk’ of California brought up north and transplanted across the border. But this isn’t an accurate description either. The climate and geology-fueled Klamath ecoregion is wholly unlike anything found in Oregon, in California, or technically anywhere else in the world.
This region is a rugged paradise wilderness existing within the larger relative wilds of the Pacific Northwest, if that can be imagined. A land of lush forests, pristine waters, bright, hot sunshine, and the overwhelming silence of isolation from humans and their business, the Klamath bioregion is an unrecognized gem in the U.S.’s crown. The region is possibly the most enigmatic and enchantingly beautiful natural space I have ever known. And to it, the following entry will serve as my love song…
