Subject: SCIENCE, NATURE, AND NEW FORESTRY ----------------------------------------------------------------------------- Comments: Steve Egeline, from the Fremont NF, offers his perspectives on topics ranging from "space and time" to "biological diversity and new forestry." There is much to ponder in the 8 pages that follow. Spend some time with this one and I think you'll find, as I did, many reasons to rethink our relationship with nature. We humans have some tough choices ahead. Steve helps us better understand them. Dve. Note: an earlier version of this paper has circulated widely in some DG circles. -------========X========------- ECO-WATCH 4/4/91 PERSPECTIVES IN NATURAL RESOURCE MANAGEMENT Steve Egeline We go about our daily lives understanding almost nothing of the world. We give little thought to the machinery that generates the sunlight that makes life possible, to the gravity that glues us to an Earth that would otherwise send us spinning off into space, or to the atoms of which we are made and on whose stability we fundamentally depend. In our society it is still customary for parents and teachers to answer most of these questions with a shrug, or with an appeal to vaguely recalled religious precepts. Some are uncomfortable with issues like these, because they so vividly expose the limitations of human understanding. Carl Sagan introducing Steven W. Hawking's A Brief History of Time. Natural resource management is really a problem in space and time, but in a perspective different from what we normally think of. We humans have spent considerable energy and thought for thousands of years in trying to understand the world around us. Beginning with the ancient Greeks right up through today's particle physics research, we humans have attempted to explain the workings of nature in terms that we can understand. Edward O. Wilson's Sociobiology, Michael E. Soule and Bruce Wilcox's edition of Conservation Biology, Stephen W. Hawking's A Brief History of Time, Desmond Morris' The Naked Ape, and The Human Zoo, and many others, have begun to scientifically explore an understanding of natural processes in ways new to us. On the other hand, philosophers such as Socrates, Plato and Aristotle, and works such as the Bible, the Koran and the Baghivadgita, have for centuries also explained nature and natural processes from differing perspectives. All of these perspectives are related, and all have their foundations in the same basic truths. However, the understanding of these truths require us to make a "paradigm shift" in our perceptions. Space and Time Let's begin by developing a concept of space and time by asking "what is nothing". Perhaps the best answer was made by a group of particle physists who were asked that question directly. Their definition of "nothing" is a state where time and space do not exist. Since time and space are relativistic concepts, that is, they are defined only in relation to other things and not to themselves, then if there were no other things, there could be no time or space, and therefore the state of "nothing" would exist. Obviously the question isn't as simple as it seems. Time/space is a measure of difference, or, differences enable time/space to exist. If things (states) change, they do so at a finite rate. Conversely, if things (states) either didn't change, or changed instantaneously in the absolute sense, it would be impossible to measure time. States of being must also be defined in relation to their locations. A fundamental rule of physics is that two things cannot occupy the same space at the same time. If two identical states exist at the same time, they must do so in different places. Likewise, if two identical states exist in the same place, they must do so at different times. In the first case, it would be possible to measure the space between the states, but not time. In the second instance, one could measure the time interval between the states, but not space. Time and space are simply different measures of the same thing, that is, difference. A state of being is defined within a few parameters. Particle physics holds that there are only four forces in the universe; the strong force holding subatomic particles together; the weak force holding atoms together; electromagnetic force measured by attraction or repulsion based on electron balance (ie. "charges"); and gravity. Some theories have been put forth to reconcile the interchangeability of the first three forces (the so-called Grand Unification Theories), and there is a major research area attempting to reconcile gravity in relation to the other three forces. General Relativity holds that matter and energy are simply different states of the same thing. That is, they are interchangeable, which is the basis of the famous formula: E = m*(c squared), where E is energy, m is mass and c is the speed of light. It also holds that rates of change are limited by the speed of light, and that nothing is instantaneous in the absolute sense. However, Newtonian theory holds that gravitational attraction is directly proportional to the masses of the two bodies attracting each other, and inversely proportional to the square of the space (distance) between them... but that the attraction is instantaneous (contrary to General Relativity and the subject of considerable research today). Another theory of physics has to do with energy, matter and order in the universe. When a given state is changed into a state of relatively greater order (regularity of organization in space or time), energy is required. The law of the conservation of energy holds that the net energy change in such a conversion is zero. However, some of the energy used in the change is degraded to a form which is no longer able to influence future state changes to the same degree. Therefore, while the change in the particular state being observed is from relative disorder to relative order, the net change in the universe is in the direction of increasing disorder. This net change toward disorder is termed entropy, and the net progression in the universe is toward a state of disorder, even though portions of the universe may become more ordered at some time (see the discussion on time/space). It could be said that there's only one state in the universe, and that is the least organized form of energy. Remember that energy and matter are interchangeable, as are time and space. The present universe is simply a particular organization of that state, observed at a particular time, which is changing in a particular manner, and its the description and predictability of those "particulars" that concerns much of science today. (It could also be said that chaos is simply a state of order that cannot presently be described, and is therefore unpredictable.) If you've followed along so far, you might be able to understand that there are two states: a relative state, and an absolute state, and that they may be the same, but most often are not. Nature and Life Our understanding of nature is based on our perspective, or relative understanding, of natural processes. For instance, consider the idea of "umweldt". This is a german word used in animal behavior, which loosely translated means "the world as perceived", which has to do with the idea that in order to understand why an organism does whatever it does, we have to understand how the organism sees (perceives) its "world" (the things and processes in its surroundings). As an illustration, let's consider one aspect of bees and flowers. It was discovered that bees can perceive (see) ultraviolet wavelengths of energy, which we cannot. It was also discovered, through the use of ultraviolet-sensitive film, that patterns exist on many flowers that aid the bee to find nectar and pollen and helps the plant reproduce. We didn't understand some aspects of why bees and flowers get along the way they do, until we understood a little more of the bee's umweldt. Its been said that perceptions are reality, but it should be obvious that it means much more than what we normally think of, since our perception of reality is based in our biological limitations on our ability to perceive. The next concept to consider is "what's the meaning of life". Now this isn't as complicated as you might think. If you have some idea of what DNA (desoxyribonucleic acid) is, then you have a good chance at understanding the meaning of life. Simply put, this is a molecule made up of a particular sequence of four acidic compounds that has the unique property of being able to replicate itself. The replicating process is accomplished through the use of highly ordered (organized) chemicals commonly known as organisms. From this perspective, the purpose of life is to replicate DNA. In other words, the organism is DNA's mechanism of making more DNA. The idea of evolutionary/genetic success is equally as simple. The particular combination of nucleic acids that produces an organism that is more successful at producing that particular DNA molecule is at an evolutionary advantage. This is true whether speaking of bacteria, redwoods, viruses, whales or humans. Because of the constant, and high level of competition in nature, which some might term chaos since many changes in nature are unpredictable by humans, species are continually evolving (changing) in order to gain whatever evolutionary advantage might exist at that point in time. (This is a particularly important concept to remember; it will be elaborated on shortly.) The rate of change in an species' environment dictates the needed evolutionary rate, but the actual rate of evolution depends on two interrlated things. The rate of evolution (adaptive change) of physical characters depends on the reproductive rate of the species. The rate of evolution of behavioral characters is dependant on the relationship of fixation of those characters in genetic material and the determination of those behaviors by learning processes. In other words, a species can change (evolve) learned behaviors more rapidly than genetically (biochemically determined) characteristics. (However, a species' capability to learn is genetically influenced, and therefore subject to evolutionary change. Sort of a circular argument.) Every species, and every individual, modifies its environment in some manner. This is done to obtain the things necessary to reproduce in the most advantageous manner in order to gain an evolutionary advantage. The products of this process also alter environments. These environmental modifications are constantly changing as the species changes, and the species changes in response to the changes in its environment (both biological and physical). The complexity of systems, involving biological and physical properties as well as dynamic cycles such as moisture, temperature, chemical, etc., is so great that it may exceed our human capability of measuring or understanding beyond a very gross scale. Let me present one last concept before specifically addressing natural resource management. Shifting to another "reality", philosophies and religions can be seen as another way of explaining states that are normally beyond our ability to understand. In this way, they can all be seen as simply different ways of addressing the same problem. However, they do it from basically two different perspectives on the continuity of life (the state of "being") and the role of man in the universe. "Western" religions usually consider man as apart from nature... usually superior, sometimes equal, but "apart", and that the soul goes "somewhere" after death.... hades, valhallah, heaven, but somewhere other than back to the earth. "Eastern" religions normally portray man as an integral part of nature... sometimes equal, sometimes inferior, but always a "part", and that the soul, upon death, comes back into that nature. The difference is in the perception of man's place in nature and of death as either absolute or transitory. Natural Resource Management Now, let's take some of these perspectives and bring them to the realities of natural resource management. As previously proposed, managing natural resources is basically a problem of time and space. Another way of looking at it is as a problem of scale in time and space, and our perceptions of scale. Biodiversity is the subject of a lot of research and concern in our management these days. However, diversity as generally conceived, is meaningless in the broadest sense. Let me explain in terms of perspectives. We assume that diversity, in terms of variety of species, plant communities, age classes and other measures of natural ecosystems, is a desirable goal to manage for. In the perception of most people, the more different things that occur in an area being considered, the more diverse that area is. We spend a lot of time and money in measuring "diversity" with the idea that if we can measure it, we can reproduce it by manipulating our environment. Lets look at diversity from the perspective of measuring it. Assume we have a finite area (space), with 50 objects present in the area. If all 50 are identical, diversity is "low" however measured. If, of the 50 objects, 49 are of one kind, and one is of another, then diversity is greater. If there are 25 of each of the two kinds, a higher state of diversity occurs, and if each object is different from each other object, a maximum state of diversity exists... until we look at spatial arrangement. Likewise, if all 50 objects occur in only one area of the space being looked at, this is a lower state of diversity than if the objects are evenly distributed across the space. And if each object is different, and the differences are greatest among those objects closest to each other, and all objects are equidistant from all the others within the space, then a state of maximum diversity exists. Now consider what the objects are and the space being considered. If we assume the objects are quarks (the most elemental particles so far know), there are six flavors, three colors and four spins known, resulting in 72 possible kinds of objects in the universe. If we try to measure diversity of quarks in the universe, the result is meaningless to the pragmatist since quarks are "too small", and the universe "too large" to be of concern. If you had the perspective of a quark, 72 different ones of you are your entire perspective, which compared to our human perspective isn't particularly diverse... after all, there are now over 5 billion of us, each one biochemically unique. Now, if you had the perspective of some astrophysists (and some might say, of God), there's only one universe, which isn't particularly diverse... only one of anything is as uniform as can be. While this example might be considered a "reducto ad absurdum" argument, I think you might be able to see the point. In general, we assume in natural ecosystems that greater diversity is better than less, but if the above concept applies, then maximum diversity is not a desirable state. For example, just looking at diversity of age classes of trees, if we wish maximum diversity of age classes, where each tree is surrounded by trees of a different age class, then the stand (area of consideration) of trees would probably not have the number (density in a given area) of large old trees we think is desirable for spotted owls or what we've termed "old growth". We need to understand that "diversity" and "variety" are not the same thing, and that before we can begin to manage for a given state of variety, we must understand and define the scale that we're managing. Let me illustrate with an argument that there is no biological difference between evenaged management and unevenaged management, only a perspective difference, defined by our biological limitations as the species Homo sapiens. Logically, if a single tree, of a single age, is cut, and a single tree of a single age grows to replace it, then evenaged management exists, just as it does if the entire forest is cut and a forest of a single age grows to replace it. Our human perspective is limited by the area being considered, which has some basis in our biology. If we cut all the trees in areas smaller than about 10 acres, we call it unevenaged management, and evenaged management if the area is larger than that. Our perspective of area, or space if you will, is based in our bilolgy as humans, our "umweldt". Likewise, our perspective of time is based on the human "umweldt". When people speak of "ancient forests", they are doing so from the human "umweldt". "Ancient" is a term of perspective. A mayfly (ephemeroptera) lives in the adult form for perhaps two days. To an Americium atom (having a half-life of fractions of a second), that's "ancient". A year-old infant is, in comparison (remember the idea of relativity?), "ancient" to Americium, but to a 40-year-old human, a 2,000 year old sequoia is "ancient", and to the sequoia, the earth is ancient, and to the earth, the universe is ancient, etc. The human "umweldt", despite our technological ability to perceive such things as subatomic particles and the "edges of the universe", is based on our lifespan and our biological ability to perceive. That's the reason we, as individuals or as a species, don't call individual tree selection evenaged management, and we talk of 500 year old trees as ancient; not because of the truth, but because of our perception of the truth, which forms our reality. Biology, Technology, and the Future Our reality is limited by our biology, just as it is for any other organism, and biology is determined by evolutionary history. It is only within our lives that we've begun to realize our intellectual perceptions, as amplified by technology, are at some odds with our biological perceptions, as determined by evolution. There is a real reason for this difference between biology and technology and their conflicting affect on perceptions, and I believe this is the root of conflict in natural resource management today. First, we have to accept that change, as defined as differences in things in the time/space continuum, is a normal (ie. expected) part of nature. That is, the processes of DNA reproduction, matter/energy interactions, increases in entropy, etc., manifest themselves as changed states, which differ in time and space. Next, we have to accept the idea that there is a limit on human understanding of these processes. When we get to the point where we no longer understand, we call it "chaos". Our ability to understand is manifested in our ability to predict the future. In other words, if we can predict a future state based on our knowledge of a present state, we say we understand that state. Finally, we have to accept that until relatively (!) recently, we humans have existed at what may be termed endemic populations as hunter-gatherers in extended (genetically related) families travelling about the landscape on foot at two to four miles per hour. Our particular advantage as a species, compared to other 100 to 200 pound land mammals, is our ability to adapt to change rapidly through modifying those behaviors which are not genetically determined. We can learn more rapidly than we can reproduce. Given these conditions, here is the reason for natural resource management conflict in our society. We do not have the ability to predict future states beyond the near future. We can't even predict the weather from day to day, let alone the condition of the earth 120+ years from now (about the "rotation age" of ponderosa pine in the west). As a result of technology... speed of mathematical computation primarily... we do, and publish, predictions on that time span. FORPLAN is nothing more than a tool to "predict the future". And yet we "know" that we don't know precisely enough about the parameters that affect the future to make any meaningful predictions. We evolved as a species to be concerned with changes in the near future, not the far future, which makes some sense because we can adapt behavior to near future conditions (the sun rising next morning, winter being cold), but not far future conditions (global warming, acid rain, being hit by a meteor, the recollapse of the universe into a singularity). If we cannot predict future conditions (states) with any degree of certainty, which we as a species have not been able to do in our evolutionary history, there is no evolutionary/biochemical advantage in changing our behaviors to address that time/space condition. But our technology is in fact giving us some glimpses of the "far future" that extend beyond our biological "near future". Our big evolutionary advantage, which is reflected in our perceptions and behavior, is based on the near future, and our management of natural resources is based on far future predictions. Our biology is in conflict with our technology, and the information necessary to address the "far future" isn't sufficient at this time, and may be beyond our ability to understand even if it was sufficient. If chaos, the inability to predict states, exists, then it is of no evolutionary advantage to adapt beyond that boundary between the "knowable" and "chaos". Therefore there is no overriding biological reason why we, as a species, can be concerned about future states beyond that time/space point. That is why the predictive arguments (FORPLAN, old growth conditions, "natural processes", regulated forests, etc.) are ineffective in addressing concerns about natural resources. We are managing based on "far future" predictions, but only perceive and react to "near future" conditions. A second part of our biology is that our "near future" perspective is based on our history. That is, our memories, both individually and as a society, are the result of past experience and are the only "known" knowledge on which we can base the prediction of the "near future". And even this past is a relatively recent past. Throughout the forests of the west, management has drastically altered the appearance of the landscape, and has in some cases caused serious resource problems.... and I'm not talking about cutting trees for lumber. The management activity has been fire suppression, and the change in the landscape has been just as dramatic as that caused by timber cutting, over a very much larger area. The difference is in the perspective of the human population. The change due to fire suppression has occurred gradually over more than one human generation, about 50 to 100 years. The perception, accelerated by our physical mobility, is that in fact it hasn't changed, since we haven't seen the change in the timeframes which we perceive. We can behaviorally accept history as fact much easier than accepting prediction as fact. Because of this, it will be much easier to discuss natural resource management on a historical basis than on a predictive basis, and the "past" timeframe is much longer than the "future" timeframe for reasons already discussed. Perhaps the first step in our understanding is to develop the perceptions that things (the landscape) have changed significantly as a result of our manipulation, though in some cases over an extended time. If we can understand that, we will be able to implement some of the landscape ecology ideas contained in the "New Perspectives" forestry. Our Future: The Role of Landscape Ecology in Natural Resource Management Where does this leave us? The key word in the ideas of the new forestry, is landscapes. What appears to be the thrust of the new forestry, or landscape ecology, is to change the time/space configuration of plants and animals as little as possible (or at a slow enough rate), preferably so it isn't obvious to our perceptions as a species, while at the same time providing the products we perceive as necessary. This being the case we accept three fairly obvious things: 1. Accept change at a higher rate (biologically very difficult as manifested in the protests against what we're doing now); 2. Reduce our demand for those products, and/or; 3. reduce our population. Of the last two, the question is "who goes first"? Whoever goes first, in terms of limiting use of resources or reproduction, loses in the near future (which is where we as a species operate), and the entire species loses in the far future if this isn't done. It could seem that much of the conflict we're seeing in resource management is an argument about "who goes first". There is a fourth solution of sorts, not without a very significant cost, but which may be worth pursuing. In order to maximize outputs, both material, biological and esthetic, from natural ecosystems, while minimizing the perception of change (particularly the rate of change), we need to radically alter the way we (both as a species and as an agency) understand nature and extract those products on which we depend. The ability to apply management (change) to as complex a system as nature requires a high degree of understanding. Understanding is different than the education which we now value. Understanding is the "umweldt" a person has as a result of education, experience, and knowledge of a particular part of the landscape. The ability to synthesize these into behaviors is often termed "skill", and if applied to non-mechanistic behavior, termed "wisdom". Basically put, we need to put our "wisest", most "skilled" people into the woods to do the work (the job of deciding what to "take" and what to "leave"), and to value the wise and skilled in our species. Training and education are a part of this valuing, but so is knowledge of the land, which can only be gained by staying in place, and only "looking" at a small enough piece of it to be able to understand. The cost of this change is real, and it is monetary. We need to have more managers since the land area with which any one can become familiar is small, and we need to provide career fulfillment in place so they have the time to develop that familiarity. We also need to find or develop people with the sense of what's been discussed in this paper to have the "agency umweldt" necessary. The idea of apprenticeship in the old world sense perhaps has some merit, and the idea of a "liberal" education can also be advantageous. Obviously, this sort of thing cannot happen simply because the Forest Service adopts a "New Forestry" perspective. It must happen because our employees collectively understand that it's necessary, and society must be willing to accept the consequences and costs of that understanding. The "New Forestry/New Perspectives" should represent a paradigm shift in our understanding of nature, including our human nature. The implementation of that understanding should be done aggressively, with full involvement of our employees and the interested publics, and in full view of Congress. In that way, we have the best chance of changing the way we do business, the way we're perceived by society, and the way we treat the landscape we live on. I hope this paper hasn't presented ideas that are totally unfamiliar, but only presented familiar ideas in new relationships.... the result should be new perspectives, which should have some influence on the behaviors which form other's perspectives of us as natural resource managers. "New perspectives" isn't a thing in the sense that individual tree or group selection harvest is a "thing"... New Perspectives is a paradigm shift in the way we think about the world around us. Steve Egeline is the Fire/Range/Wildlife/Fish/Soil/Water Staff Officer on the Fremont National Forest. This "perspective" was written about a year ago when he was District Ranger on the Heber District, Apache-Sitgraves NF
