Nomadic life will continue (8/21/2023)

It has been a few weeks since I checked in here on my blog, but so be it. I can notice that my readership has declined somewhat during these past two months, but maybe I can atribute that to the vacation that many are having, my retirement, and all the things going on in my life. For one we had some major structural work done in our home. This cost gobs of money, but we justified it by the fact that we are healthy, plan to live here for at least another 10 to 15 years, and it would increase the value of our home. It may in the long run even save us money.

But this is not what I want to write about. I am writing to forewarn you, my dear readers, that the nomad will be resuming his nomadic lifestyle during the month of September. We are planning a trip across the country to attend to family festivities in California. Yes, we will be doing this with our camper van, the Ford Transit, that we recently purchased from friends. I already wrote about some dress rehearsal camping trips here and here.

The trip is estimated to take two weeks to travel from the east to the west coast. After the festivities we will need to return home and we have no idea yet how long we will be taking to accomplish that or the route. Naturally, I will try to write about our trip (both going and returning); maybe not a daily report, but I hope to write a regular dispatch from the road. I really hope to give you all an idea of what we are experiencing and how I am feeling. It will include reviews of the places (camping areas) we stay; places we visit; walks and hikes we do; restaurants we eat at; maybe some microbreweries or wineries; or even some knitting shops.

Are we preparing? Yes, we are! On our way out west we are planning to roughly follow the Lewis and Clark trail, at least to the Montana-Idaho border, or the source of the Missouri river before turning south towards the Los Angeles area. I have been reading various books including the book by Stephen E. Ambrose entitled “Undaunted Courage, Meriwether Lewis, Thomas Jefferson and the Opening of the American West,” Julie Fanselow’s “Traveling the Lewis and Clark Trail,” and Alain de Botton’s “The Art of Travel.” As you can see, I always have a number of books open, but that’s me. I have been booking camp sites and figuring out the best routes to drive. We’ll try to stay away from the interstate highways once we reach St. Louis, the “official” start of the trail.

We have given ourselves 14 days to get across; however, there are a lot of unknowns. Of course there is hurricane season. We really wondered why the festivities were planned at the height of this time of year. Twenty years ago, our area was hit by hurricane Isabel on September 18, and our party is on September 16 in LA. Our area sustained major damage as a result of Isabel’s passing; we lost electricity for 13 days. Hurricanes have been in the back of our mind ever since during the month of September and leaving home that month is somewhat scary. In addition, leaving my bonsai trees for more than a few days worries me somewhat, although I have an automated watering system and my neighbor Bob promised he would keep an eye on them.

A final item is of course not knowing what to expect in the northern states. This includes the weather and animals like bears. Will it be cold in Montana, will we be bugged by grizzlies? Yes, I already loaded a space heater, which will only work when we have shore power, and I bought bear spray. Reading accounts about van-life in Reddit, I learn that van floors are notoriously cold and poor Radar (our dog) who sleeps on the floor was already shivering when the outside temperatures dipped below 60 degrees Fahrenheit. But then today it is 102 degrees in North and South Dakota.

All this thinking and anticipation reminds me a little of what I read in The Art of Travel about that subject. Botton writes about de Esseintes, a character in J.K. Huysman’s 1884 novel A Rebours who was a great armchair traveler full of anticipation but was bitterly disappointed when reaching his destination and almost immediately returned home without completing his planned visits. In other words, we will see how this will all pan out. I am sure that there will be days when we will be disappointed, and days when we will be ecstatic; tired days and days that we want to keep going. After our 6 days of camping in July we felt great and were ready for more. So hopefully this will be fine too. Stay tuned.

The rear of the van has been decorated.  If you are a reader on the trail we are following and you see these decals, come and say hello.

Bonsai lessons (8/7/2023)

I had the pleasure the other day to have a grandmother and her grandson over to look at my bonsai trees. The grandmother is a friend from the yacht club, and she had heard that I grow bonsai. Her teenage grandson had tried to grow a bonsai from seed; however, it never germinated. We had already made two appointments, but they never panned out, and this time they were 30 minutes early.

It was fun to be back somewhat in the teaching mode. We started out looking at my 35-year-old Siberian elm, this is one of my favorite trees and it is in quarantine. The quarantine is not because of disease or something like that, but somehow when it is on the tables where I keep my trees, the Japanese beetles find it and it seems that only hit my three Siberian elms. I have a stand of canna lilies nearby and they are a favorite of these ferocious insects in my yard. But somehow when I move them away from my tables and the lilies, these elms are more or less safe from these bugs.

Walking around the tables and showing them my little trees was a lot of fun. The kid was very inquisitive, and grandma could not get him away from the place. He seemed particularly impressed by the tree (cherry) which I had to go at with a saw-saw or hacksaw. The root was simply too big. Grandma was impressed with my American hollies; she hates those prickly leaves. Fun was talking about my citrus trees that I grew from seed. As I told them anything is possible, with a little knowledge.

We talked about styles; how to miniaturize the leaves; root pruning; best time of year to work on them; pots; and of course, soils and fertilizer. I have written about this before, but it seems that everybody wants to buy a bonsai tree or has bought one once in their life. I think at least 95% of them invariably die within the first few months.

Most of this is soil related, the trees at the big box stores usually come in crappy soil in pots that don’t drain very well. The result is root rot when the temperatures rise in the pots, and they do not drain. Plants die or at least get weak. What to do? Repot? If you do that, you kill the poor guy. No, we just need to make sure we do not over or under water too much and we might want to protect the container from overheating. Additional issues seen is the lack of light. Folks put their first bonsai inside on the coffee table. However, it was an outdoors tree that likes full sunlight. Death is imminent. Finally, folks may start pruning or shaping to quickly and weaken the tree.

We talked for over an hour and a half. It was fun talking about my trees and what I do with them, my plans and more. It was just plain fun interacting with someone who was interested in my hobby and sharing these things with him. It made me feel good for the rest of the day.

The lower trunk of my Siberian elm.  It is approximately 35 years old and was developed from seed.  In the soils post that I have link to above, there is another picture of it.  This tree has gone all over the country with me and has been ignored for a while.  It is finally on a decent trajectory.

This is the cherry that I got earlier this year.  It was a thick stick in a pot with a horrible root.  I used the hack saw to cut 2/3rds of it and planted in an Anderson flat.  It seems to be doing well.  I have no idea what styling decisions I will make in the near future but will probably have to cut it shorter.

One of my hollies.  Maybe not really visible.  It has been in a pot ffor at least 7 years, I dug it up in my yard.

The citrus plants grown from seed.  This is their second summer, and they are enjoying themselves.  I have a few oranges and lemons, all grown from seeds.

Are we part of a holobiont? (7/29/2023)

If you haven’t been living in a hole in the ground, you must have heard about the word or concept called microbiome. Microbiome is defined as the community of microorganisms that exists in a particular environment. These can include fungi, bacteria, other singular cellular organisms and even viruses. When we look at us humans these are our gut bacteria and everything else that is down or better in there. Moreover, it seems that even our hands, our body and every other part of our body have a unique microbiome. The microbiome on our left hand might even differ from that on our right hand. Being a baker, I listened to a podcast on sourdough breads and it seems that every sourdough baker has a microbiome on their hands that is unique to the sourdough starter they use.

The microbiome seems to be responsible for a lot of things in our life including gut health; our resistance to diseases; dementia at older age; and even our mental health. It appears we have more (micro)organisms in our gut microbiome than cells in our body. We are what is considered by some scientists a holobiont.

A holobiont is defined as an assemblage of a host and the many other species living in or around it, which together form a discrete ecological unit. In other words, we as individual humans and our microbiome together are holobionts. There is still some controversy about this concept of holobiont and even my spell checker does not know the word yet.

What medical science is slowly telling us is that if our microbiome is off, we get in all kinds of trouble. The simple issue maybe diarrhea or other stomach upset. It may include weight loss or conversely in folks who suffer from obesity. As I mentioned above, it seems that Alzheimer can even be linked to our microbiome being out of balance, or at least it can excel the mental decline or onset of dementia in some. We can change our microbiome with the food we eat, and this is where the concept of not “not every calorie is the same” comes from. We are hopefully also all learning about probiotics (fermented foods rule), prebiotics, and now even post-biotics. All parts of a healthy nutrition that is good for gut health. Folks with CDIF (or Clostridium difficilus), a very virulent bacterial infection may even require a fecal or poop transplant to get a healthy microbiome from someone else implanted in their gut. Which might be the only way to shake this disease.

Anyway, I want to stop here, and write more about the concept of holobiont. This idea, an assemblage of a host and other species living together in some form of harmony is interesting to me and to a lot of scientists. I think this is what makes it so darn controversial. One of the reasons is that if we look at it on a large scale, we can look at an island or even the Earth as a holobiont as well, and that everything living on this earth are part of that assemblage. Ah, we are quickly entering the world of Gaia and I think this is where the whole concept of holobiont runs into trouble. Gaia is more metaphysical; it seems to be more the believe in the divine personification of the Earth and the matriarch of all things in existence. Modern pagans believe Gaia is the Earth and she is the spiritual embodiment of the Earth. In other words, scientist that consider the Earth a holobiont are skating on thin ice and can be accused of being pagans or some other form of religious heretics.

However, the concept is an interesting one. Like our gut with diarrhea, the earth can also get or be out of balance when the assemblage of species gets out of balance. An interesting concept isn’t it? It is somewhat Malthusian, but I am beginning to believe that we are exceeding the carrying capacity of the earth; the carrying capacity is the number of individual humans the earth can safely handle before things go awry. In my eyes, we humans could be considered the E. coli of even CDIF of the Earth. There are just too many of us, and the Earth is sick! That is what I think we are seeing, global warming, the weather is going bonkers; everything seems out of balance. Even today there was a report that the gulf stream that keeps western Europe warm may be diminishing and put Europe in an eventual deep freeze. Strange days indeed! Have we reached the point of no return? I don’t know, only time will tell.

During our hike last week we encountered communities like this.  Although not a holobiont, the lichen on the rock are a perfect union of algae and fungi living together in perfect harmony.  In addition I just loved the community of plants.  This was in Grayson Highland State Park

Zombies (7/27/2023)

“It must be the zombie apocalypse” was our reaction, while sitting in the parking lot of the Burger King in Hillsville, Virginia. A sirens was going off, an ambulance was coming by, various fire engines, and not to count the large number of police cars. We were on our first real camping trip in our van; post retirement. Somewhat of a dress rehearsal for our coming trip across country, and also just our first real vacation. (By the way, I am borrowing the zombie apocalypse metaphor from Nigel Saunders from the Bonsai Zone who always uses that phrase when he hears a siren.)

We left home on Monday morning for the Rocky Knob Camp Ground on the Blue Ridge Parkway, just outside Floyd. We planned to stay there two nights, knowing well that there would be no electric hookups; water was available at the restrooms. In other words, camping was relatively primitive. It proved to be delightfully true when we got there. It was a larger campground than expected, and the camping spots were fine. It took a bit of adjusting to get a somewhat level site, but by the second night we were fine. We had taken the van out to go to a magnificent hiking spot (more about this a little later), followed by lunch at a winery and a visit to Floyd which was downhill from the campground. So, when we returned, we had learned our lesson and parked the van at a more level position.

After two nights, we packed up and drove to Grayson Highland State Park. Their campground is much more developed; it has running water and electricity. Spots are tighter together, and here again, partially because of my choice and because of the vehicle, getting a perfectly level (sleeping) site was difficult. However, the second night was a charm. We stayed in the park, did some magnificent hiking and after two nights, we moved to Highland County to visit friends where we camped in their driveway but ate and showered in their home. My wife even managed to break their toilet seat cover. The following day we drove home.

What amazed me the most about both camp grounds was that they had volunteer hosts. These were older couples in their 70s and 80s who stay at the place for free and help with hospitality and in the camp store (if there is one). Something to consider.

The hiking:

In the Rocky Knob Recreation Area, we did the Rock Castle Gorge Trail the first day. We only did the lower part, approximately 2.8 miles each way, although our FitBits told us it was closer to 3 miles (so 6 miles total). It is an absolutely gorgeous trail. A fairly moderate hike (on the easy side of moderate in our eyes), with some nice up hills and vistas along a wild creek. It was extremely enjoyable. We topped it off with that visit to the Chateau Morrisette Winery for a glass of cold white wine and a cheese plate for lunch. The winery is very dog friendly; I highly recommend a visit to this winery. The location, vistas, layout and the wine a super.

On our way out, on the second day we walked the 3-mile Black Ridge Trail. This trail was also very nice, somewhat slightly more challenging, but very pleasant with some nice vistas. This trail has much more variability in the landscape; however, both trails in this area were great.

In Grayson Highland we only walked one trail. The 3.7-mile Stamper’s Branch Trail kicked our butt; however, it was great! With the 3.7 miles I mean that the trail is actually only about 1.9 miles each way and it leads from the camp ground to the visitor’s center. The trail has an elevation gain of close to 900 feet and let me tell you, these 70-year-old knees felt it. Moreover, coming from sea level, I noticed that we peaked at an elevation of almost 5000 feet. Grayson Highland is near Mount Rogers, Virginia’s highest mountain. I enjoyed the types of vegetation we hiked through and we even saw a bear in the far distance.

So how did my bonsais fare while we were gone? I had received a LinkTap Wi-Fi watering timer what is called a “tap linker”. This is a Wi-Fi water timer that opens a valve to a hose on which I had two sprinklers mounted. I had the sprinklers go on every morning for 20 minutes. Let me tell you, from the looks of it my plants loved it. They look lush and in much better shape compared to when I water them by hand. Thank goodness, my neighbor Bob was also looking out for them, and all was good.

In all, we had a successful trip. We now feel much more comfortable and want to do again. Living the retired life! Not like zombies.

Stormwater, the early years (7/10/2023)

In a previous post I mentioned that I once had the ambition to write a book on stormwater and erosion and sediment control (and I may still do it). This idea was a natural outflow of the job I did pre-retirement. The following post is part of an introductory section that I wrote for the book. Ince I lifted from a chapter, I have changed it a little to make it a narrative for you all to follow and understand. I left the literature citations out, feel free to contact me, if you are interested in them. So here I go:

Very early, North American settlement history may have followed similar patterns as were encountered in Europe of the Middle Ages. The settling population in North America initially concentrated in towns and villages for mutual protection from outlaws and native Indian population. This is evident by some of the older larger urban centers on the east coast. In addition, large tracts of land were deforested very early on in settlement history for the use of timber (building materials) and the growth of cash crops, in particular tobacco. A 17th century document in the historic town of Williamsburg describes that climbers of the church spire in town (or what is now Colonial Williamsburg) were able to see the York River to the north and the James River to the south, a feat that is impossible nowadays because of the regrowth of the forest in the area. The peninsula appeared to have completely deforested, mostly for the growing of tobacco at that time.

The cartographer Lewis Evans observed the same thing when he reported in 1750 about the deforestation and conversion to agriculture land that had already greatly altered the hydrology and clarity of streams and creeks in the Piedmont of Northern Virginia:

"When the country was cover'd with Woods, and the Swamps with brush, the rain that fell was detained by these interruptions, and so had time to insinuate into the Earth, and contribute to the springs and runs. But now the country is clear'd, the rain as fast as it falls is hurried into the rivers, and washes away the earth and soil of our Naked Fields."

 

The reports by Evans were only the beginning. Human caused accelerated erosion increased steadily as is shown in a recent study by Kemp et al (2020) who conclude that European settlement of North America during the past century has resulted in the movement in as much sediment that natural processes can move in 700 to 3000 years. They estimated that geologic sediment production which had been relatively stable for the past 40,000 years increased 10-fold as a result of European settlement and the rapid expansion of agriculture and river modification seen throughout the continent.

So, what are currently the main sources of sediment the waterways in more developed nations? It was reported that while agriculture practices generate considerable amounts of sediment by way of erosion; we now estimate that areas cleared for construction are able to generate the equivalent of many decades of sediment in one year compared to agricultural uses (let me know if you are interested in the source). Research determined that construction can yield 140,000 tons of sediment per square mile per year, compared to 1000 tons from agriculture land and up to 500 tons from forested land in the Piedmont area of Maryland. In other words, construction is a major contributor producing 140 times more sediment than agriculture land per unit area (for example per acre or hectare). However, , there is so much more land being used for agriculture than actively being disturbed by construction activities.

On an interesting note, while sediment production increased at least 10-fold over historical times in North America during the last century, it was also observed that during the same period it seemed that less sediment reached the ocean. This was caused by the retention of the sediment by reservoirs that were constructed by human. Reservoirs served for the storage of drinking water and water for energy generation and irrigation. It has been estimated that a total of 1.4 ± 0.3 metric tons of sediment per year is retained by reservoirs world-wide. Siltation of these reservoirs will eventually greatly reduce the capacity, function, and usefulness of these structures. It appears that Indonesian rivers were a rare exception and that they deliver more sediment to the coastal areas than other rivers that they surveyed.

Here I’ll step away from my book chapter. I saw similar issues in Nepal where the land or better fertile soil was being carried away by runoff. The main reason was deforestation for agriculture. We often joked that a new island was being formed off the coast of Bangladesh. This island was formed from the sediment being carried by the rivers coming out of Nepal. The results in Nepal were the drying out of springs and dropping groundwater table, a phenomenon seen throughout areas that are being deforested.

I’ll end here, there are many posts where I discuss some of these items as well. Just look in the keywords for the words like stormwater, erosion, sediment, erosion and sediment control, runoff reduction and alike. If you like or enjoy what I wrote here, let me know and I’ll pull some additional material out of my writing.

Our daughter was in New Delhi, India these past few weeks and sent me this newspaper shot.  They had 6" (126 mm) of rain in the afternoon and it flooded the town.  Can you imagine all the impervious area in such a large city, it created havoc.
