Chris,
First, I must say, my comment about airline security was in reference to commercial airlines that us poor saps who aren’t in the Air Force and who don’t have the ability to be “doing mock five, with your hair on fire!” But then, you knew that 
You’re right, we are basically on the same page, but as I have said before, “the devil is in the details!” Habitat destruction is, in most but not all cases, the biggest problem species face. Unfortunately, there are many desirable species whose habitat is still present, but over collection has placed serous doubts on the long-term survival of the species. This problem is particularly onerous in the tropics where species have relatively small ranges (i.e. a single valley or mountain top), and can be easily collected to extinction. The bigger concern I have is for species whose habitat has already been reduced to a small park or preserve to protect the few remaining populations of a species, and poachers go into those areas to collect the rare animals that thus command a high price amongst unscrupulous collectors, and like it or not, unscrupulous collectors are rampant amongst our ranks. This is why I have been advocating for the majority of herpers, who would never buy one of the last few hundred flat-backed spider tortoises stolen out of the in-habitat breeding preserve a couple of years ago, to stand up and say this kind of behavior is no longer acceptable!
Let me put this another way, if you cut the available habitat of a species in half, what do you have? The answer is half the number of animals. Animals in nature, occupy the habitat to the fullest extent that habitat, which includes the food and other resources needed by wildlife to live, can support. If you decrease the habitat by bulldozing it, the displaced snakes, for example, do not move into the remaining habitat, and go on like before with an increase in the number of individuals in the remaining habitat. The habitat can still only support X number of individuals, and in many cases in North America the remaining habitat is also compromised by pollution, LOGGING (which produces a monoculture forest with little value as habitat for most forest species) etc. thereby reducing the number of animals it can support, so the displaced animals often die or displace animals already present in the remaining habitat that also die. The result, half the habitat…half the animals, but this assumes that the remaining habitat can support/contain the biology of the animal (e.g. The home range of an Indigo snake is huge for a reptile, which is one of the main reasons why they aren’t doing to good. This is also why large predators are often the first to go in a disrupted ecosystem). Then, if we add, as you suggest, a road through the remaining habitat, we introduce a random mortality factor that can have severe long term effects on population numbers and demographics (i.e. the new individuals from the destroyed habitat move in once to help replace the road losses, but the road is there for good, and roads more often than not get bigger and more busy resulting in greater mortality over time). Now, on top of all that, you want to continue the collecting of animals from that habitat? Let’s face it, in the last twenty years the amount of natural habitat available for wildlife has been cut by a third to a half depending on which part of the country you live in, and in that same amount of time the number of herpers has increased by some 500% or more! Can you see the problem here? Yes, habitat destruction is the biggest problem most species face, but the coup de grâce for many herp species could very well be over collection and poaching of the remaining individuals in limited habitat!
Species go through population cycles, but we humans, in our infinite wisdom, have decided that nature always produces more individuals in a population than can survive, so we can harvest those “surplus” individuals with out harming the actual population. Well there are three problems with this, and I don’t even want to call it a hypothesis because it does not even have enough science behind it to call this idea a hypothesis, assumption. First, natural populations fluctuate as environmental conditions change, and more often than not, we humans seem to be unable or unwilling to detect these changes, and we are only just beginning to be able to predict how small changes in the environment will affect population size. The result, we take the same number of surplus individuals from the population regardless of how conditions change. Yes, this may be fine for a while, but it is like playing Russian roulette with half the chambers full! Look at the sardine industry collapse for the classic example, or if you like some more recent examples, look at the newspaper stories on the hake, tuna, shrimp and many other fisheries or look at deer populations and hunting regulations over the last five years. Second, populations produce surplus individuals for a reason. That reason is “survival of the fittest.” Put in simple terms, ‘cause I could write a book on this, surplus individuals need to be produced in a population to provide the raw materials for selection to occur. Some individuals are born with less adaptive genes and they, and their genes, are selected against thereby leaving the “better adapted” genes in the remaining population. The result is the local population is “better adapted” to the local conditions over time, or put another way, the “weak individuals” are removed from the population leaving the “stronger individuals” to produce the next generation. Unfortunately, we humans harvest the individuals we find, which are not necessarily the “weakest”, and in fact we often hunt for the healthiest looking individuals when we collect, so we are a random force that actually helps to decrease the adaptation of the population to the local environment, and thus, we reduce the populations long-term viability or survival probability. Third, the number of “surplus” individuals in a population is an entirely subjective guess for a particular population and has no relevance to other populations, and this assumes that there was even an effort to determine the number of “surplus” individuals in the first place, which in the case of herps, there generally was not. As I said, continuing to collect individuals from the wild is like playing Russian roulette with half the chambers full, and trying to justify continued collection because habitat destruction is a bigger problem, simply does not hold water. In this case, like many others, “if you are not part of the solution, you are part of the problem,” and continuing to collect animals from wild populations is contributing, in a small but significant way, to their demise.
Now back to the topic, wildlife laws are intended to stop, or in reality decrease, the illegal harvesting of wildlife for commercial purposes, be it for food, pet or pelt. Game Wardens need to be able to enforce those laws within the Justice System we have in place here in the US, and our system is set up to make it difficult to put innocent people behind bars, which unfortunately means it also makes it difficult to put the guilty behind bars. The deck is stacked against the Game Warden and in favor of the criminals. If we open up commercial production of all native species it is going to be difficult to impossible to enforce anti-poaching laws because the Game Wardens will not be able to “prove beyond a reasonable doubt” that a poacher is removing animals from the wild, so the poachers will be given free rein to take all the animals they want from the wild without any fear of being caught. Placing “loopholes” in the law will only make it more difficult to impossible to put poachers behind bars. No, that’s not fair to you and others who have the best intentions with breeding native species, and who want to do things legally, but again, look at the big picture. Do you really want to protect species in natural habitat, or do you want to be able breed anything you want in your basement (garage, den or where ever)? What is your real ultimate goal?
As you said, education is the key, and people need to be educated about how our legal system operates. Laws are by definition punitive in nature. They are not designed to keep honest people from doing what ever they want, that is an unfortunate side effect. Laws in the US must be designed to keep dishonest people from doing what ever they want, and to be able to realistically enforce those laws we must draw a line somewhere or the lawyers will make everything gray. Trust me when I say our system is far from perfect, but it is a whole lot better than the legal system in most other countries. In Zimbabwe, for example, if you are caught more than half a Km from the road with a gun of any kind, a snare or a machete in a wildlife park, you are shot on sight. There is no trial, there is no explanation of your intent, there is no giving up to the police, you’re dead. Our system is a whole lot better than that, but with our kind of freedom comes responsibility, and we all must take responsibility for our actions and the effect of our actions have on the people and world around us, as they say “no man is an island.” If people want to say that their intention is to conserve species, fine, but put your mouth, actions and your money in the same place! You cannot say your trying to conserve species and continue to buy wild collected animals.
Further, education is necessary, because most people are unaware of how their actions translate to the bigger picture. Let’s return to the forestry example where I talked about how unfair it is that our tax dollars are being used to support the logging of our National Forests for the benefit of a few wealthy people, and you said, “Because we, the taxpayers, both allow it and condone it (through our continued use of wood products).” I don’t honestly think that most people actually realize how much of their tax dollars are being spent supporting various programs, and even fewer people realize that there are alternatives to wood frame houses that have many benefits over wood besides the ecological ones. However, people are creatures of habit, so until they see the real need for change they keep plugging along in the same old way looking for the wood frame houses they are use to, and in so doing support the continuation of logging and the resultant environmental degradation. If people were truly aware of how much logging is costing them in terms of taxes and ecological stability, I think people would make better choices.
The common excuse people give for not making ecologically responsible choices is, “there were no cost effective alternatives that were environmentally friendly,” which is where legislation and education can be beneficial. Look at the auto smog laws in California where you live. California had a real bad smog problem, but the auto manufactures were not adding pollution control devices to their cars because it would increase the cost of their cars and the competition would take away their sales. California’s Air Resources Board passed a law setting emission standards for all new cars in incremental steps of ever more stringent standards. The auto manufacturers complained bitterly that it would drive them to bankruptcy and consumer groups complained that the cars would be too expensive. However, the law equalized the stage for everyone and let the free enterprise system dictate how the manufacturers met those goals while still remaining competitive. Because all manufacturers were required to meet the same goals the cost deterrent was reversed. If a manufacturer wanted to compete in California, they had to develop the technology, but because it was required on all cars, the manufacturers could quickly recoup their costs, and car prices stayed down. Now the technology developed in California is being sold across the US because it is cheaper to manufacture one car for the entire country than it is to manufacture one car for California and another for every where else (I know this is not true in all cases, but without CA’s restrictions, the rest of us would probably still not have smog devices on any of our cars. Now if CA would only tighten up the pollution standards of SUV’s we could see another quantum leap in improved air quality). Now CA is requiring that a certain percentage of cars sold in CA by a particular manufacturer be low emission, so the price of hybrid and electric cars went from the $50,000-$60,000 range down to the $25,000-$30,000 range where some of us can actually afford to buy them. With out the incentive of law, hybrid cars would probably never have been developed, and if they were, they would be too expensive for anyone to own. These alternatives are now available, but people have to buy and use them, which is where understanding the “big picture” and an environmental education come in.
Wildlife laws are the first step in protecting the species we love, understanding why those laws are in place, obeying them and ultimately actually protecting species requires people to get educated and make ecologically responsible choices. If you keep your eye on the “big picture” it will make the sacrifices we all must make to conserve species a little easer to make.
Finally, I have one bone to pick. You state, “I have a general disagreement with the philosophy of people who petition for laws, or who author/sponsor laws, the subject matter of which they have little to no first-hand experience with. It's one thing to do a summer of field research on a species, but an entirely different matter to live with that species on one's own property for several generations, but have your personal observations dismissed as "anecdotal" while the academians push legislation on how you are allowed to use your land.” First, anecdotal data, as defined by law (under NEPA), is any data that is included in an environmental impact report that has not been published in a peer-reviewed journal. It does not matter if it is a scientist who supplies the information or a landowner; if the data is not published it is considered anecdotal. Second, most land owners who complain about environmental laws are generally people who decide they want to do something entirely different with their land than what it has been used for in the past, such as turning a pasture into condominiums, so their anecdotal data is immaterial to the new land use, and in most cases the land owner did not even know what species of salamander or frog were on their land in the first place. Third, most professional herpetologists I know working in the environmental protection field grew up collecting herps just like the rest of us, and most keep at least a few herps as pets. These are people who are smart enough to have figured out a way to get paid to do what they love. Further, they have spent years studying at the university to complete degrees in their field, and many of them have dedicated their entire careers to studying a particular species or group of species, so saying their information is based on a summer of field research is not only unfair, it is not true. I hear these kinds of comments all the time, and they are simply based in nothing more than jealousy. Academics are down in the trenches fighting to save species every day in an up hill battle with little hope of real success against big business and politics. They deserve our support and our respect, not unfounded cheep shots.
