The Turtles Provide Lessons for the Future

Filed under: Life — Cynthia Ann Whelan @ 9:39 pm

I became a true believer in conservation when my son told me “Mom, let’s give the turtles some space.”

Back In 1977, when I was fresh out of high school and discovering the world, I realized I really enjoyed traveling. At that time, I was a poor college student and the easiest and most economical way to travel was to sign up for fieldtrip classes. What could be better than college credit to travel and study the biology and geology of the Hawaiian Islands?

On that trip, I had a stimulating time in Hawaii identifying native plants, visiting archaeological sites, and seeing aa and pahoe pahoe lava. I and my classmates went scuba and skin diving daily and studied parrot fish, angle fish, Moorish idols, moray eels and turtles. The nature guide books said that were turtles in the Hawaiian Islands and the instructors insisted that there were turtles somewhere among the islands, but they were rare. This was true, because during our four week study of the islands, no one in our group saw a turtle.

Exactly one year after my visit to Hawaii, on July 28, 1978, the green sea turtle was listed as a threatened species under the Threatened and Endangered Species Act.

Twenty five years later, I was very excited because I was returning to Maui, and this time I had the opportunity share my knowledge of the biology and geology of the Hawaiian Islands with my two children.

We stood on the beach and before us rolled the big blue Pacific Ocean and I was anxious. It made me uneasy to trust my offspring to the wild of the open sea. My family and I donned our fins and snorkels for my children’s first skin diving experience. With my son close at hand we paddled and swam around. It was amazing to small children that “there’s fish just swimming around in the ocean” and there was nothing to keep those fish from swimming wherever they pleased! Since this was our first excursion, we didn’t want to get too far out or too tired. We’re on our way to shore, feeling very accomplished, when my son suddenly stops me. There ahead is a turtle. It was as big as he and only a few feet away. I found myself experiencing that same childlike surprise and wonder; “there’s a turtle just swimming around in the ocean with no barriers and he can swim wherever he wants!” I knew then that seeing a turtle in the wild would be a highlight of our trip, but it didn’t end there. We went snorkeling at another beach, and there were turtles, and at a third location we saw more turtles; big, beautiful, slow moving, nonchalant, turtles. During our ten day trip we saw over a dozen green sea turtles just swimming around wherever they wanted.

On one occasion, in my excitement I was encouraging my son to see just how close we could get. “Come on, let’s get closer.” I urged him on. He didn’t follow but instead, he stopped me with caution, “Mom, let’s give the turtles some space.” He was right. We backed off, and watched it overtake us in its slow hulking swim. It was then I realized that over the last twenty-five years, green sea turtles were given some space to live and carry-on and flourish. They were beautiful, and I was able to share that awe and wonder of discovery with my children.

Conservation works, we just need to give it some time and space.

What You do Today, Will Cast a Shadow on the Future

Filed under: General — Cynthia Ann Whelan @ 11:35 am

This week I attended “Strategic Project Level Assessment for Hydroelectric Projects”.
The objective of the class was to discuss the strengths and pitfalls of applying simulation models to make administrative decisions about the future environmental conditions of aquatic habitats associated with hydroelectric projects.

Models are a very linear subject. But instead of taking linear class notes, I took a more circular, rounded approach. The following are my philosophical reflections on the use of environmental models:

The Future
* Sometimes we forget that our perceptions of the future affect our daily choices, and out daily choices affect the future. Chicken or egg?
* How appropriate is it to use a projection of the future to make decisions today? Some models are more appropriate than others.
* Future decisions and decisions about the future depend on what you choose to acknowledge and what you choose to ignore.
* Science, technology, data, and priorities are changeable. ‘Facts’ today may be very wrong tomorrow.
* Decisions about the future need to have a bridge for retreat. For you to retreat, and for others. Try to keep a way to maintain face, respect and efficacy.

Timing
* Decisions move around from raw to ripe to rotten.
* Expect change and prepare to have the endurance to act when the decision is ripe.
* The 800 lb. gorilla can shift over time. Different emphasis can occur at different times. Carefully choose when you use your weight. Tomorrow, you may be a 50 lb. weakling. Be humble.
* Decisions can be immediate or time integrated and adaptive – standard setting with one result, or incremental results that may change over time. If change occurs over time or volume what is the marginal cost to benefit? How much is adequate?
* Don’t start with your end, and always know when to end.

The Unusual Circumstance
* Infrequent events can get masked out and are sometimes disregarded.
* Unusual events in models may not be real or even possible.
* The extremes are suspect and should be looked at outside of the established conventions.
* Decisions based on extremes or the unusual are suspect.
* Worse case may need to be addressed and/or eliminated.
* Extremes are not an indicator of success
* Extremes or the unusual may be beyond any management controls.
* Understand where you have accuracy and where you have precision.

How Much is Enough?
* Overly general decision criteria can lead to decisions that can justify just about action now or any desired result in the future.
* Methods that incrementally evaluate factors are complex, and there is more opportunity for mistakes and manipulation. Sources of error can compound the errors or results.
* It is hard to define limits, decision points and desired results when sliding scales are used. First, you must define a process on how you will agree on the results or final outcomes, and then evaluate the scales.
* Always compare what comes out of the model to real data.
* How many samples do we need to take? Until we feel good.
* It is hard to mess with Newtonian science, but rivers are not Newtonian science.
* Choose a baseline because there is no absolute reference, there is only intrinsic/relative meaning.
* Invest in skill and quality.
* Are you evaluating an index of occurrence or index of severity? You can pick indices that suit your situation or criteria.

People
* Human interpretation is everything! The good, the bad, and the ugly all depend on who is making the call. “Did I get what I want?” is the yardstick.
* If at first you don’t succeed, try, try, again. Diligence pays.
* Faith, perceptions and personal values count and will affect the end decision.
* People make mistakes. Always work with a copy. If you screw up, you can go back to the original and start over. Back up your work, and if you make a mistake, go back.
* Go to the field. Nothing beats standing on the ground and making a reality check. The art of land management is not dead. Your guts are good.
* If they can’t tell you who, what, where, when, and how they collected the data, the data is garbage. They are either incompetent, or they are lying.
* Models are just as good as the operator(s). They integrate in ways that help, but you need to understand how to represent the processes you want to imitate and you need to understand how to adjust the knobs.
* Simulation models are not honest. People are, or are not honest.
* It is all about control – competitive and positional.
* The devil is in the details, and the details can be hidden or they can be enlightening.
* Be nice, but firm.

“You can’t always get what you want, but if you try sometimes,
you get what you need.”
