On trainers and teaching, Part VI, what walls? (11/25/2015)

It is always interesting to see that when you start something it has unforeseen consequences, in particular when they are positive.  Call it serendipity or coincidence, but it is often not the intent.  In my case, it brought down a few walls, or boundaries.

So what am I talking about?  As I recently mentioned in a post I was developing a course on wetlands and how it relates to stormwater and erosion and sediment control.  We felt there was a tremendous need for a class like this, since we always talk about wetlands in our classes and the need to avoid impacting them.  We felt that I was the person to do this because I have worked as a wetland scientist throughout the U.S.A. since the early 1990-s.  Well, we have rolled out the class and given it at two locations.  The class has been well received and the evaluations are great.  Both the materials and the teacher (me) are well liked.  So there is something to say for being multifarious, a jack of all trades, it helps in thinking things through in developing a class and standing in front of a room and talking about a subject.  I discussed that in this post as well.

A tidal salt marsh in a creek that is a tributary to the York River.  Tidal marshes are really interesting, to the eye they may seem fairly uniform and only occupied by a single species.  But this is far from the truth.  During high tide they are teaming with small (young fish) and at low tide they have fiddler crabs and other critters.  The plant species in them have a very narrow tollerance range of water (tidal) depth.  It is a really neat system.

Why then the unforeseen consequences?  That for a big part may have to do with my personality.  While I love to teach and be in front of a class; I hate to practice, do dry runs of my classes, tell people how it goes, what I am doing, you know it.  I find it difficult to develop outlines of what I am doing or how the class will go (a waste of time almost, I rather be developing the class or think about it).  For me developing a class is an organic I start out with a few ideas and things go from there I put things before it and behind it, wherever it makes sense in my eyes; I brood.  This can be infuriating to my supervisor, although he has learned to live with it and understands it.  However, you can imagine that people who do not know my style and more vested in the subject matter can get concerned when they experience my style first hand.  I do not like to rehearse my classes, and when I do, I find it difficult to treat a group of my colleagues, who I assume know as much as I do of the subject, as the students I am supposed to teach and know very little.  It feels like I am talking down to them and that is something I cannot do.  I like to talk to people at their level, which is probably why people rate me so high as a teacher (am I too arrogant here? I really don't like talking down to people, unless I don't like them, then I talk down to them like the best of them!).  Moreover, I do not rehearse my classes.  As I tell my students in the first class: “You guys are the dress rehearsal and the main event all at the same time!” 

During the development of the class I’ve felt two or three times that the class would be cancelled because of the sensitive issues that wetlands raise in this country.  We understand more and more about their importance as an ecosystem and habitat that needs to be protected, and for that matter the push back that conservationists have had in the past from the development and home building community.  So it is logical that this class was under somewhat of a microscope to start with.  Moreover, people are protective of their own turf, so it is difficult to have an outsider like me teach a subject that another group in our department is responsible for; they are the experts and they had no idea what my level of expertise was or what my teaching style was.  On top of that was my style of course design and development (in other words don't do as I do when you do course design) and my marginal ability to articulate it.

However, I can report all is well and I have received compliments from the group that considered asking us to cancel the classes and we received an offer from them to co-teach the class with me, the greatest compliment I can get.  I consider it a breaking down of a virtual wall between groups that is there whether you want to admit there is a wall or not.

But one thing is for sure you never get to tear down walls or get these neat unforeseen consequences if you don't try!

And yes, I need to really try to be more transparent in my course design, I guess.

Yorktown (11/11/2015)

The leaves are falling!

The leaf of a sassafras tree/shrub; one of my favorite species.  I just love the trident shaped leaves and while I do not like the taste of root beer, I love the smell of the crushed leaves which smell like root beer.  Old folklore tells me that in the south people would crush the roots and make tea from the roots claiming that the tea would make them better able to deal with the heat and the humidity of the summers.

Fall is definitively here.  It always seems to hit hard in November (see my post from around this time last year).  It is around Thanksgiving that I rake, blow or mulch for the last time.  The roads in our neighborhood are beginning to be lined with clear bags with leaves that are going to be carted off to the county's composting facilities (I hope), and maybe next spring these same people will bring some of the leaves back in a different form to fertilize and mulch their yard; although I would not bet on it.

Many of these people mine their yards for nutrients.  In one of the classes that I teach I surprise my student with the little factoid that fall leaves contain a lot of phosphorus and by us carting leaves of to the dump or to the composting facility we are really mining phosphorus and depleting our soil.  This forces us to go buy fertilizer at our landscaping stores and put artificial fertilizer on our lawns and gardens which we basically cart off again next fall.  The fertilizer companies  (and the garden stores) love us, don't they?

Our neighborhood has them all, there is this one guy, I swear, he gets the blower out when he sees one leaf on his lawn or driveway (he's obviously OCD).  My wife and I call him "Jack the Blower".  He has the leaf blower going for at least two hours every Friday, Saturday and Sunday (we are not home the other days so we don't know if he blows those days as well); one wonders what else he does in life, or if he has a life.  I feel sorry for his neighbors; who have told me that they actually caught him blowing leaves into their yard.  When we lived in Cincinnati 20 years ago, we knew an equally OCD guy (an ex FBI agent) and when we walked by his property we made sure to bring a leaf and  place one leaf on his lawn, just to tease him.  Boy, we were mean in our younger years.

But leaves are important, as I mentioned, they recycle nutrients and organic matter, but they also are the home to a lot of insects and other critters.  It is a lot of fun to see towhees and brown thrashers going after bugs in the leaves in my yard.  They do it just like chickens scratching away in the leaves, throwing them all over.


I took this photo a couple of days ago behind our home and titled it: "Fall massacre in full swing

But there is more, all the mushrooms that are out there are fed by the decaying leaves and rotting plant materials, salamanders lizards, frogs and a lot of other critters need them.  The fallen leaves serve as natural litter that keep  the weeds from growing; although, in some cases to much litter may be a bad thing as I complained about in an earlier post.  There is too much litter in the woods behind our home, which in my eyes has suppressed the native weeds and forbs.  The only way to remedy that would be with a controlled burn and good luck in getting that approved.

But again, it is important to mulch the leaves back into the lawn and back into the flower beds.  The organic matter, nutrients, weed control, and habitat for our wildlife provided by those leaves is so valuable!

Stormwater (11/1/2015)

I have been doing some literature research on the history of stormwater management.  OK, call me a stormwater geek or a stormwater nerd, but I just realized that I have been actually fascinated about it for probably more more than forty years and I never noticed it until this weekend.

It all started in 1972 when I read an article somewhere about an agriculture and reforestation project in the arid mountains of Algeria.  This fascinated me and prompted me to do a literature search on the subject of desert revegetation at my college library in Holland where I found a reference to a new (scientific) book by Michael Evenari and co-authors called: The Negev, The Challenge of a Desert.  It was published in 1971 and I borrowed it through inter-library loan.  It came from the Dutch Library of Congress, it appeared that I was the first one to read it.  I devoured the book.

In this book Evenari and his colleagues describe how the old Bedouin tribes were able not only to survive in the desert but actually to thrive by practicing agriculture in the Negev Desert of what is now Israel.  They built extensive drainage canal systems on hillsides that captured runoff from the sparse winter rainstorms and brought the water down to the agriculture fields.  Very different from what we did with stormwater until the early 2000s; which is, getting rid of it.  At least now we are back to teaching people to conserve stormwater; to conserve it and infiltrate it.

Walking to work in Richmond this morning (11/3/2015), ready to go back out on the road and teach about stormwater management and conservation, and erosion and sediment control. 

I have always credited Evenari for steering me into the field of desert ecology; his book has a chapter on plant survival in the desert environment and it was my first encounter with that subject as well.  Ever since reading that chapter I have been fascinated with plant physiological ecology, in particular the adaptation of plants to stressful environments such as deserts, the subject I specialized in for my PhD.

Events in real life kept reminding me of Evenari's book.  In Yemen I saw some of the same water harvesting practices that he described seeing in the Negev Desert.  I also saw the same plant adaptations in Yemen and in New Mexico as he saw, and it always brought me back to his book.  So much so, that  Evenari's book was one of the first purchases I made on the fledgling Amazon.com years ago, it was a book that always stayed with me.  So yes, it was fun to open it again this weekend and to leaf through it again.

Now 40 year or more later I can credit Evenari for even more than just turning me into an physiological ecologist.  Truth be known, I am more a stormwater geek or nerd now; maybe also thanks to that book, a realization I all the sudden have all out of the blue.  It is fun to see how your life comes full circle, all the way back to stormwater management, the most important subject in the book.  It is amazing how one event, or one book can have such a (subconscious) influence even if you don't realize it then, but only now 40+ years later.  I am sure that many of you have events, books or even radio or television shows that are somehow pivotal to your career or even your life, that you do not realize until many years later.  Cherish those moments, I cherish mine right now.

On blogging, course design, photography and training (Fairfax, 10/20/2015)

I am having a comfortable landing (I hope) just good, there were a lot of loose ends are being tied down, like in the closing of the year.  I have therefore not written much these past two months; I am way to busy for that.  Yes, consider this a good thing.  I just have too darn much to do or to look forward to.  Here are some of the things:
  1. It is the end of the sailing season; if we are lucky we'll get a few more nice days in.  As a rule of thumb, we try to sail on black Friday (the Friday after Thanksgiving for you non-U.S.A. residents, when most of the people seem to go Christmas shopping) and that generally is my last one for the year, at least on our boat.
  2. I am done with my class designs for this years' classes and now I have one and a half month of heavy teaching (and travel) to look forward to (the photo below was taken at 8 pm in a Starbucks in Fairfax while I was writing this blog).
  3. I am starting to think about new classes: a photography class, a hydrology class and a class on soil amendments.  How is that for diversity?
  4. I have got some other irons in the fire that I cannot write about (yet).
  5. In addition the days are getting shorter (bring on Seasonal Affected Disorder or SAD, at least for some, but I think we all slow down when fall and winter rolls around)
  6. Finally, one of my co-workers is pregnant, which is great, but it will probably mean a more intensive travel schedule for us next year.  If I was a mother of a new born I would not want to go on overnight trips without the kiddo, especially if I was breast feeding.
On the road again.  My evening coffee at Starbucks, waiting for my computer to start up.
So yes this blog may suffer somewhat.  But I will really try to keep it up with a few interesting items, maybe not about my travels throughout the state, but more about my job and research.  I do not want to make this a "dear diary," so don't worry.

If you write a blog your self you know that there are many pages behind a blog.  I can check how many people read my posts, broken down by post, by day, by week, month or even year.  I know how readers got to my blog: by accident, via another website, what search engine they used, even what browser they used, you name it.  I even know what country they come from (surprise, most of my readers come from the U.S.A., but Russians are running second, followed by Germans and the French).

A lot of bloggers are in it to make money.  Yes, I could allow Google or Amazon to put advertisement on my blog and every time you would click on an add, I would get maybe 5 cents or something like it.  There are even blog posts about boosting traffic to your site like this one: <click here>.  This is how some bloggers are hoping to strike it rich and this is why they create these outrageous blogs.  Who knows, I may eventually break down and allow adds on my site, in the hope that you the readers will make me rich!  We'll see.

As I mentioned before, I started this blog for myself; I wanted to get back to photography and get into writing.  My wife and I had so much experience working all over the world, we felt that those experiences needed to be documented, if not only for our daughter, for future generations.  Moreover, I feel I have so much more to give.

So yes! I am going to teach a photography course again.  The last one I taught was in 1977 while serving in the Dutch Army as the Installation's photographer.  It is fun doing research on photography, or at least slowly trying to get slides together on items such as ISO setting and photographic noise (yes there is such a thing; we used to call it grain when we worked in film).

I took a photograph with my cell phone of a book case in my office from a distance of 12 feet at three different ISO settings (Auto, 100 and 800).  As you can see the ISO 100 setting produced the least noise, the problem is the shutter speed (your lens has to stay open longer), and at low light the camera set at ISO 100 might be subject to movement/shaking of the camera/phone.
I know most of it, but now try to put it in a three hour class that is useful for stormwater inspectors.  Who knows, I may need to make it a six hour class.  We could do so much, even a practicum and have them go out and take pictures; although then I would need to limit the class size (we usually limit our class size to 40 but as a solo teacher I could not manage 40 in the field).  There are really so many photo tips and tricks I could teach them (and you on my blog; if you want to learn more, let me know and leave me a comment).

As I mentioned, I will also be teaching a class on hydrology and in a future post I will be writing a little bit about that.  I found some really neat stuff on some of the history of stormwater management, some of which has fascinated me since I was 18 and enjoyed observing in Yemen when I worked there in the mid 1980s.  Yet another subject dear to my heart.  Stay tuned!

Richmond (10/5/2015)

It's been an interesting weekend, and we in Virginia had it easy compared to the Carolina's.  Let me explain:

When I took the first picture on Wednesday September 30, the clouds were building and the weather outlook was for a lot of rain and a possible hurricane over the weekend.  Predictions were at the time that hurricane Joaquin was going to come right up (what we call) the main stem of the Chesapeake Bay as a category 1 or maybe even a 2 storm, and for us who lived through hurricane Isabel, we feared the worst.  I took this photo, in anticipation that it would look very different a week later.

A picture of the James River in Downtown Richmond from Brown's Island Park taken on 9/30/2015.
There was this European model out there that was sowing doubt in our mind.  In the past the European hurricane model had been the most reliable, so were were all somewhat skeptical about the initial dire predictions of the other models, and we did not really make many hurricane preparations.  From the look of it some people did, because when the I visited our local Lowe's on Friday after we were sure that the storm was going to pass us by, the return line with people returning unused generators (still in the box) was very long!

The next photograph I took on the 5th of October after the mountain region of Virginia received a lot of rain and you can see that the water is much muddier and that it has risen a lot.  There was a sandbar in front of one of the bridge pilings and that is now underwater; moreover the first section of the piling is almost completely submerged.  What a little rain in the watershed will do!  Actually the week before September 30, the mountainous region of Virginia received close to 8 inches of rain in 2 days (for my non-American readers that is 200 mm) and during the "hurricane weekend" or the weekend before the 5th we got another 2 to 3 inches (50 to 75 mm).  After a little lag time as they call it in hydrology (it takes a few days for all that water to flow down hill), we saw the water levels rise.

The James River on October 5, 2015.
As of the writing of this blog (10/8/2015) the water level in the river is back to the level of the first picture.  Again, this is nothing compared to what the people in South Carolina are going through.  My hearth goes out to them.  The climatological extremes seem to be getting more frequent, fires out west, floods in the east.  As predicted, global warming is slowly expressing itself isn't it?
