The Devolution of Thought and Evolution of Species
As yesterday would have been the 201st birthday of Charles Darwin I found it overly ironic that all I saw on the news was a barrage of people declaring that global warming was a farce because it had snowed outside. I have to admit that I am starting to find the snows I have missed from my youth a bit annoying now. However it hasn’t effected me enough to start denying reality and the evidence of real science. I may be delirious from cabin fever and the total loss of routine from an ad-hoc school schedule, but it is not about to lead to the closing of this American mind.
Had it not been for the steady drumbeat of an old friend’s facebook status, Chuck-D Day might have slipped by me completely. This friend is someone I new well in my youth. For many years as children we spent every daylight hour walking up an down our town’s railroad tracks and creeks collecting turtles, snakes, frogs, salamanders and any other little critter we could get to ride home in our pockets. Of course we evolved over time, and got smart enough to carry buckets and boxes. At one point we even moved up to traps and converted a neighbor’s walk in aviary into an all out zoo. This particular friend is now a Herpetologist and was leading a read-a-thon in which they finished the Origin of Species in approximately 18 hours. (I can only assume this was faster than the last time.) As I watched the devolution of our politicians minds on TV his constant updates assured me that somewhere someone was actually evolving.
As for my own celebration, it was going on in my head all day. As I spent all day listening to the talking heads knowing full well they were incapable of thinking, I was thinking about how I became most aware of global warming through the spread of invasive species. Over the years I wasn’t always aware of either problem, it took a move to a different climate to make me see how differently things react under the slightest change. It became even more evident when I began working across the 3 distinct zones from North Georgia to Virgina that I could see how differently species adapt and react to different ecosystems. Hybrid Burning Bush and Barberry that for years no one would have imagined spreading are not only growing from seed, but they are adapting and moving into climates that normally would have been to cold for their seed to survive.
When I hear people talk of climate chance, I always hear about it’s effect on water, and people. How the oceans will flood the cities, rivers will run dry, and other factors that we see directly related to our needs as humans is all that seems to matter. The only time I hear plants discussed is in how trees can offset carbon so we can create more. Unfortunately I hear more talk about whether the change exists in the first place, than what we can to do prevent it. However, more than fighting of global warming plants can help us see and understand it.
In some respects plants are the antithesis of humans. Plants adapt and get stronger every year and can live several of our lifetimes, but they create a new generation and pass on those traits every year. When winters were consistent invasive species were easier to keep in check. The annual minimum temperatures used to keep the non-native seeds in check year after year. As winters have gradually warmed, those seeds have have adapted and become more cold tolerant as those few extra degrees have allowed them to survive. Now they can handle the extreme conditions that now occur once every five years instead of annually. We on the other hand have not adapted. Burning Bush that used to be contained to areas near it’s cousins in Georgia are now making their way up the coast to New York. Princess Trees, Barberry, Butterfly Bush, English Ivy, and many more are making that same journey. In less than a generation of our lifetime, these species have adapted to the climate change and produced dozens more generations while we are still arguing over whether it even exists.
As humans we are different from plants. We may live for decades but usually only reproduce during a short window of that time and in small numbers. While we do physically evolve generationally, we usually reproduce at a peak moment and then actually become weaker for the next two thirds of our life. Plants and trees that can live hundreds of years get stronger and reproduce every year until that last year of their life when they actually produce the most seed. Where we differ is in that we have minds that can evolve way beyond our physical bodies. However, unlike a tree whose wood gets harder with age and ease, we have to work and use our minds to keep them growing even as it gets harder. If we don’t do this, collectively as a society we can actually get weaker and devolve. The more we separate into individual pockets of though and deny the science that exists in nature around us the weaker we actually become as a species. Too often because of our self awareness we lose the awareness of the world around us and slow the evolution of our collective conscience.
In the United States we track plant hardiness and nativity with the USDA system for for classifying plant hardiness known as the USDA Zones. The system is based on a ranges of temperatures, recorded temperatures by areas, and the minimum temperatures those plants can supposedly take. The system isn’t based on where these plants should grow, but where they could grow. It also only covers minimum temperatures and not maximums. Even more odd, this “could” focus is based on how we can use plants to alter the environment through a commercial view not how to protect and preserve it. This is from the Department of AGRICULTURE though, not the Environmental Protection Agency. Throughout the world these systems vary, but an emerging and evolving trend throughout the world does not start with temperatures, it start with plants. Aerial photography is used to map where the species that form the canopy are, and the undergrowth can be determined by combining that and other data; yet another Copernican shift in the right direction. People are actually using plants to gain perspective rather than trying to fit them into their own perspectives and learning more about themselves and the world in the end.
Unlike trees, if our minds continue to grow after reproduction we cannot continue to pass it on year after year through our seed. Even what we do pass on isn’t the content of thought, only the ability. We can only continue our evolution as a species through education. The strongest ideas aren’t the ones that are said the most often, screamed the loudest or that have the most money to advertise them. They are the ones that come from listening, hearing, and collectively evolving with the world around us. Our evolution as a species is dependent the recognition of our role in the community of species, listening to each other within our species, and admitting that trying to be the strongest being isn’t necessarily in our nature as a species, and doesn’t make us the fittest species. As a species we can learn a lot from the trees around us, but the message we should learn isn’t to reproduce like the Duggars. It is that the world is changing, and for us to become the fittest species possible we have to continue to evolve mentally every year, even after our body ceases to evolve. The lesson is that our seeds are seeds of thought, and without them our minds cannot grow and neither can our species as a whole.
It is funny how we all develop. I probably could have guessed that my friend leading the read-a-thon would grow up to be a turtle hugger. As for me, while I was in horticulture at a young age, the technology I work in now was still in the form of a punch card and we couldn’t have seen this coming. There was a third member of or 9-10 year old research team, and I don’t think I wouldn’t have guessed the future for him either. He is writing his dissertation on the effects of invasive species on soil fertility in the upper Midwest. However, as kids nature planted seeds in our minds, and as we moved to different climates those seeds evolved with the world around us. I guess our evolution is proof that passion can evolve into thought and doesn’t have to lead to the death or denial of it. When I look at how we’ve grown, it is reassurance to me that for us to remain the “fittest” species we must continue to evolve our minds and realize that we are part of a community of species. Likewise, by denying evolution, including climate change, we deny our role in the community of species, weaken our collective mind and species as a whole, and jeopardize the species Earth as we know it. How this all came about isn’t what is important, but acknowledgement that it exists and our role in it is vital to our development as a species and to the survival of the world as we know it.


It’s an age old question that can apply to many things. Names are something we take for granted, but in reality they are the fundamental basis of all communications. When we think of names we think of what we call one another, our pets, our children and our places. In reality though ever word in every language is in essence a name. Even a verb is the name for an action that takes many words to explain, that is why they all have definitions. Imagine trying to give someone directions without a name for the action of “turn”. Most importantly though, we use names to explain relations. First names, last names, family trees, nationalities, and the names for the relations between these things are what derive and keep order in our world. Even further they are the signposts to how we navigate and determine our possible impact on and place in the world. Names of course vary among languages and regions. Different words (names) are used to describe the same thing in different languages and locations. In the end, regardless of differences in language, the objects and actions being described by their name can be recognized for what they are and the variations in language can be translated.









To wrap things up, lawns represent a vital part of our natural ecosystem. They serve functions that are vital to wildlife and nature as well as our nature as human beings. As long as we take nature’s cues on when to use them and don’t try to grow them where they don’t belong or want to be there is nothing unnatural about them at all. What is unnatural is what we have been doing to them.

Castanaea dentata (American Chestnut): This tree is one of the most known stories of eco-catastrophe in our countries history. The Chestnut was the most coveted of all lumbers in the early part of the 1900’s. As a result was the clear-cutting of almost all of the Southern Appalachians. The practices were horrid, and reminiscent of a scene from a slaughter house, but of trees. Lumber that wasn’t seen as fit to mill was left in place leaving entire mountains looking like salvage yards. Stumps were left in place, and all of the ground vegetation was smothered under the debris. Erosion was rampant, and as a result these wastelands became a breeding ground for what would become the Chestnut blight. Species such as the black bear were almost completely lost, deer populations dissipated, and without the nuts to forage or forest to find protection from hunters Elk eventually disappeared.
Ulmus americana (American Elm): In the first half of the 1900’s this tree was the most common street tree in the United States. It’s arching branches formed cathedral ceilings over almost every street in every city. It become an icon of American urbanism and the America Beautiful movement. It fell victim not to greed of harvesting, or destruction of its environment, because this tree grew anywhere. Rather it fell victim to careless breeding and commercialization that weakened the species. While Chinese and European varieties were being imported for breeding to create fancy bark or brighter fall color, no one realized that they were weakening the species and importing a deadly disease that would bring the native species to its knees.
Pinus palustris (Longleaf Pine / Southern Yellow Pine): The Longleaf pine was on of the signature trees of Southeast coastal regions. This tree is very unique in that for the first eight years of its life it grows like a fireproof grass with no trunk elongation. Then it shoots up and it sensitive to burns, but once it reaches about 10′ it becomes fire proof again and soars to heights of up to 100′. This burning process is crucial to its reproduction and the culling of healthy forests. The lush wild look this process creates was the image that was burned into the minds of explorers when the new world was being discovered. The unique habit created by the juvenile plants provide habitat to all sorts of foul and wildlife and as their habitat has become endangered so have some of them. Red-cockaded woodpeckers and indigo snakes are most at risk, but tourtouses are in line right behind them.
Quercus virginiana (Southern Live Oak): Yes, this tree is the one we have embedded in our heads from movies like Gone With the Wind, and every other great southern movie or novel. As we see them in all the urban settings and plantation gardens you would not think something this majestic could be in any sort of danger. The Spanish soss and fern growing on its branches make it look as thought this species is drooping from the weight or its virility. However, in its native habitat it is almost gone. The boggy soil and forests of the deltas where it thrived have mostly been drained for drilling, sugar cane, and development. These trees made up the buffers that used to protect New Orleans from the onslaught of hurricanes. There ability to be uprooted and fall apart but continue to grow in the loamy soil that was once its home was the constant stability that held the delta together. Now their native habitat is down to a few remaining national and state controlled forests. Of course other species have been impacted, but the most famous impact was the damage from Katrina that was exasperated without the natural buffers these trees created to protect it.
Tsuga hetrophylla (Western Hemlock) & Tsuga caroliniana (Carolina Hemlock): Both of these trees have suffered similar fates. Both are the victims of over logging. Unfortunately both were thought to be invincible as they grew like the Red Cedars of the Midwest on either coast. In the East the Carolina Hemlock was hardly ever used for lumber, They were usually casualties of careless Chestnut and Oak harvest and turned into pulp or used for fuel. By the time the species was decimated people had realized it was a beautiful lumber and turned to the bountiful west coast for the Western Hemlock in its place. Neither were able to come back as fast as they were being harvested and as a result the faster growing Tsuga canadensis (Canadian Hemlock) and various Pines have taken their respective places.
Picea sitchensis(Sitka Spruce): Another victim of logging, this species is also succumbing to the woolly adelgid. One of the more tragic consequences of this parable is that this tree is the home to the endangered Spotted Owl. When the fight over protecting the owl versus the right to harvest came to a head the harvest rate increased dramatically as it turned into a race to see how much people could harvest as while they still could. As timber containing adelgid infested lumber moves up and down the highways it just spreads it even more. In the end both the owl and the loggers are losing out as they are losing the tree they both covet so much.
Thuja plicata Western Red Cedar: This tree has been devastated in its native habitat due to logging for pulp. However, it is thriving and making a surge in cultivation. As the Hemlocks and Junipers used in landscapes have become more problematic and disease prone, this tree grows with relative ease. It struggles to outpace the pines that are moving into the native habitat because the Pines grow larger and shade them out. While in the landscape people are finding this to be a great native alternative to give the feel of a Canadian Hemlock without the adelgids or chemicals to keep the bugs at bay. However do to massive logging its natural disbursement patterns have been disrupted permanently and it may never be able to reestablish itself against the more aggressive species taking it’s place.
It’s that time of year again. I’ve cleaned out the tube bird feeders, hung a couple new suet feeders, and I have already had on ripped down by the bear. I always like to wait until winter is really coming to start feeding. Primarily because I like to let the birds “Free Range” on wild flower seeds and the summer fruits and berries in the garden. I like the thought of them helping with the natural cycle of scarifying and dispersing the seeds the way nature intended. I also like not having the bears visit everyday, especially with my daughter playing outside by herself all summer. This is a luxury we have living on a rural mountainside that we didn’t have on an urban street corner. Not that the bears are the threat that some of our neighbors were. They are more akin to urban raccoons that scavenge their way around on garbage day and pilfer your bird feeders.
Pinus (Pine): There are dozens of native pines that make great trees for birds. Pinus Strobus (Eastern White Pine) is the most commonly planted in the United States, but for smaller varieties in residential gardens some other native options include Pinus aristata (Bristlecone Pine), Pinus banksiana (Jack Pine), Pinus Bugeana (Lacebark Pine), Pinus Resinosa (Red Pine), and Pinus monophylla (Pinyon Pine). These pines are all more moderate in size than the White Pine, but still maintain a natural feel in a formal landscape. This makes them ideal for urban or residential situations.
Juniperus (Juniper): Juniperus communis (Common Juniper), Juniperus monosperma (Oneseed Juniper), Juniperus occidentalis (Western Juniper), Juniperus scopularum (Rocky Mountain Juniper) and Juniperus virginiana (Eastern Red Cedar) are the most common native varieties in the continental United States. Between these five you can find a native Juniper almost anywhere in North America. All of these varieties have been cultivated into varieties for landscape use that can be safely used without worrying about reseeding invasive offspring. If seed stock does emerge it will come out as one of the native varieties. There are some hybridized varieties that could revert to something else, so if trying to stay native stick to cultivated or native varieties only.
Viburnums: Viburnums are a favorite of landscape designers because they are extremely hardy They also produce nice flowers, foliage and berries and provide some great fall color. Some are even evergreen, and the flowers are often extremely fragrant. However, they are usually somewhat of an unknown to beginning gardeners or casual retail nursery shoppers. Native species include Viburnum dentatum (Chicago Luster Viburnum), Viburnum prunifolium (Blackhaw Viburnum), Viburnum rufidulum (Rusty Blackhaw Viburnum), and Viburnum trilobum (American Cranberry Viburnum), All of these plants have abundant flowers and berries and can be kept as large shrubs or small trees in any landscape. The birds love them for the berries and their height is achieved with fairly small horizontal branches that are great for perching but don’t hold the weight of predators making them a nice place for birds to hang out. There are also many cultivated and hybridized non-native varieties that are not invasive. If for some reason a native option doesn’t work for you, I would not hesitate to explore those options.
Cornus (Dogwood): Everyone thinks of Dogwoods as the spring flowering tree, however they also come in some naturalizing and shrub forms as well. Cornus florida (Flowering Dogwood) is a sentimental favorite for gardeners with the pink and white flowers at Easterand red berries in the fall. However Cornus racemosa (Gray Dogwood) makes a great naturalizing thicket of about 12-15 feet and produces a nice white flower in May and June and a waxy white berry birds love. Other varieties include Cornus alternifolia (Pagoda Dogwood), Cornus drummundii (Rough-leaved Dogwood), Cornus nuttallii (Pacific Dogwood), and Cornus sericea (Red Twig Dogwood). The Rough-leaved and Red Twig Dogwoods provide a shrub form and the red twigs provide great winter interest. All of these plants have wonderful landscape value, as well as make great naturalizers. They all have reliable berries for the birds, provide nesting habitat, and add aesthetic value to add to any garden.
Prunus (Cherry): The Prunus (Cherry) family covers more than the cherries we eat or the flowering trees we see in spring. There several shrub forms and not as showy trees that can add subtle accents to the landscape, as well as habitat and fodder for birds. Prunus virginiana (Chokecherry) comes in several forms and varieties and is a great alternative to some of the hybrid and grafted tree-form varieties. Prunus caroliniana (Carolina Cherrylaurel) and its Asian counterpart Prunus lauroceasus (Cherry Laurel) make great evergreen shrubs, providing both protection and berries as well as a nice evergreen foliage for the landscape. Prunuis subhirtella (Weeping cherry) is a nice pink flowering native that drops small berries mid summer. Prunus besseyi (Sand Cherry) is a great naturalizing shrub with small white flowers and black berries that are low enough to provide fodder for foraging birds like pheasant and turkey. Finally, Prunus americana (Wild Plum) is probably one of the most common fruit bearing trees and can be found in almost all states east of the Rockies. Of course there are other varieties as well, but as a family, Prunus may provide more food for the birds this continent than any other plant family.
