Nature-deficit disorder (Yorktown, 11/25 and 11/27/2015)

A real term or not?  I strongly believe it is.   Just like attention deficit disorder (ADD) is, there is something to being too long away from the natural world.   While people with ADD can not focus on one thing for an extended period , I believe if you have nature-deficit disorder you need a regular nature fix or you can no longer fully focus on life or the task ahead or other things like depression set in.

I did not invent the term, or the concept.  I was introduced to it by Richard Louv in his books "Last Child in the Woods ..." and "The Nature Principle."  While maybe no literary masterpieces  (says this non-native English speaker and amateur blogger), the books introduced me to some great concepts and ideas that I intuitively knew, but never articulated.  They really are great books.  Being in nature recharges me and brings me inner peace.  Mr. Louv even has examples of bringing peace to inner city gang members by bringing them to nature. (See also this webpage on the movement he started).

Readers know I am a biologist, a naturalist and an educator who loves the outside, both the blue and the green.  I suffer terribly from nature-deficit disorder, I need to get out there after a few days (just to recharge and get my sanity back).  If you are a regular reader you should know, and just look at the labels, there are at least 21 posts where I used the term.  So on my first day off on the long Thanksgiving weekend I took off for a walk in the woods with the dogs.  It was just above freezing and sunny; perfect.

To me walks like this are like meditation, the mind goes where it wants to and you observe it.  If it goes too far you call it gently call it back.  You don't speed walk, but just observe.  But still, I actively look around, observe and take photos.  Here are a few photos I took during my walk:

Teaching my wetland class, I always walk around with my teacher hat on and had to take this photograph of three multi-stemmed red maples in a row.  A clear sign that this site may be wet, or at least as I say in my class, "a red flag."

I was somewhat surprised to find this turtle on my path.  It was a cold morning and I was expecting that they were in hibernation by now.  The dogs sniffed it and you could hear it clicking in the shell making sure it stayed closed. 

Right after seeing the turtle I was struck by the way the sun was shining through the trees and striking the ground, the trees, and my face.  I just had to take this picture.   At home I converted it to black and white.   

I found it so encouraging that the outdoors store REI started the #OptOutside movement for Black Friday.  They did not open their stores on Black Friday  and encouraged their employees to enjoy the great outdoors.   We did the same, we took the sail boat out and enjoyed blue nature. It all fits in with fighting Nature-deficit disorders.

Enjoying Blue Nature on Black Friday.

Being out there is so important to me.  Try it, it is good for the soul, the mind and for those creative juices.

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.
