Springfield Botanical Gardens – April 2023

/

The uptick in vegetation is in full swing at the Springfield Botanical Gardens this month. We went on a morning cool/breezy enough to require a jacket with a hood and gloves. The early blooming trees and bushes (cherry, magnolia, quince), spring bulbs, and some violets made it worth the walk. The magnolias appeared to have been hard hit by the cold weather of the past weeks – with wads of ruined flowers; but some buds were evidently not impacted, and the few flowers were a taste of how grand the tree would have been without the cold weather.

As usual, I couldn’t resist some macro shots. In years past, I have often contented with very active bees, but the breezy cold must have kept them away. I didn’t see a single insect on the trees. The picture of the ‘open’ redbuds (last picture) was one of my favorites.

But – my favorite of the morning was the tulips. Not all the tulips were blooming quite yet…but these very bright flowers stood out in their brown mulch bed. I liked their color and spikey shape!

I am looking forward to seeing how the gardens change by May!

Coppell Nature Park

/

Coppell Nature Park is about 15-minutes from my parents’ home in Carrollton, TX. I enjoyed my first outing there last month. It is a 66-acre park surrounded by ball fields and playgrounds of Wagon Wheel Park. There is a Biodiversity Education Center there is well (although I didn’t go in). The trails are mulch covered…the vegetation leafing out for spring. I took some macro pictures of ‘new leaves.’

I took some macro pictures of ‘new leaves.’

There is good signage on trees which would make it easy to teach yourself tree recognition….even in the winter! Persimmons are one of my favorites with their blocky bark.

The only wildflower I saw during my short walk was common dewberries….prickles.

The forest views are good but the sound of airplanes overhead is a frequent distraction. I’ll have to go back next month explore more fully (I’ll print the trail map) and see how spring is progressing.

Bluebonnets and Dandelions

/

I looked for bluebonnets on my March road trip to Texas, but only saw them in two ‘cultivated’ places: at the Texas Welcome Center on US 7 (just after the bridge over the Red River from Oklahoma) and at the Coppell Nature Park. Maybe it was a little early to see them along the roadsides (or maybe there are not as many growing ‘wild’ anymore). Even the places I did find them were not dense stands that I remember. I’ll be looking for them again during my April road trip. They are the state flower of Texas!

Dandelions were everywhere during my road trip (and also at home). They are deep rooted plants growing in a variety of places that have photogenic flowers and seed puffs….and are an example of a garden plant cultivated by early European settlers that escaped into the wilds of North America. I enjoyed dandelion greens from my CSA in Maryland, but it’s too challenging to get the soil grit cleared from the shorter ‘wild’ leaves (I.e. so I haven’t eaten any recently). Most people attempt to keep their yards free of dandelions; I did that for years and have now decided it is futile. I’ll mow them…but that’s it. I tell myself that their deeper roots reduce soil erosion. And they support pollinators!

Carrollton Yard – March 2023 (2)

/

Continuing the report on my parents’ yard….

It’s not just flowers that were blooming. The crane flies emerged while I was there. They seemed to be everywhere. One got in the house and stayed put near the door…posing for portraits. Later I saw one on a plant. These short-lived adults are eaten by birds (as are the larvae in the soil)!

Of course – there are still flowering bulbs, sage, wisteria, and daisies blooming around the yard too.

The pecan tree had tuffs of leaves and blooms. It’s a young tree…maybe this year I will make pecans.

The sweet gum was also leafing out. It is fruitless variety (i.e. no spikey seeds). The tips of its branches are still very complex.

My favorite picture of the yard this month was some red yucca seed pods from last year….still holding the black seeds….the old stalk bent almost to ground level so that the leaves of the plant form the background.

I am looking forward to seeing the changes that April brings…

Carrollton Yard – March 2023 (1)

/

The next few months, until the heat of summer becomes oppressive, should be the prettiest months of year in Carrollton, TX yards… including my parents’ yard. There were so many things to see when I was there in late March, that I am writing about them in two posts (today and tomorrow).

Seeds from a neighbor’s tree were all shades of green to brown….blowing over the back yard (will any of them sprout?).

The usual early spring flowers were up. My mother cut some of them to bring indoors; the garden still held plenty more.

The fiddleheads in the front flowerbed were healthy looking. They survived the prolonged period of 100 degree + days last summer better than the blue rug juniper ground cover (more than half of it died). Being in the shade most of the time must have helped although some of last year’s fronds looked burnt in August.

I was surprised to see several clumps of mushrooms around the base of one of the old mulberry trees. The tree itself was leafing out…so it’s unclear why that grassy area was so hospitable for mushrooms. I took the opportunity to do some macro photography….of course.

I enjoyed two servings of edamame pods and composted the empty pods afterward in one of the flowerbeds. It is surprising how much happened to them in 2-3 days! I’ll check them again in late April!

Gleanings of the Week Ending April 8, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Avi Kwa Ame, Sacred Land in Nevada, to Be Preserved as a National Monument – Good! Another place to see when we make a trip in the west.

Volvo Delivers Its 1st Electric Heavy-Duty Truck in Africa – The truck is being used for collecting waste in Rabat, Morocco. Morocco is also home to the world’s biggest concentrated solar power facility.

A 90-year-old tortoise named Mr. Pickles just became a father of 3. It's a big 'dill' – Radiated tortoise native to Madagascar and critically endangered…at the Houston Zoo.

One of Europe’s last free-flowing rivers declared a National Park – Albania’s Vjosa River. Europe is also removing dams along other river just as we are in the US…but rivers that have been controlled by barriers will never be the way they were before the dam.

Clinics on wheels bring doctors and dentists to health care deserts – It’s a step forward and might work well for preventative or chronic care…but what happens in cases where the need is more urgent…like broken bones, having a baby, the aftermath of a car accident?

Technology over the long run: zoom out to see how dramatically the world can change within a lifetime – A graphic from ‘Our World in Data’ – worth the look. See the big developments they selected occuring during your lifetime….and when technologies we take for granted came along.

Take a Virtual Tour of the ‘Doomsday’ Seed Vault – Its doors are only opened a few times each year for new seed entries. The seeds come from countries from all over the world and are kept at -18 degrees Celsius. The most recent withdrawal was to re-establish a seedbank that had been destroyed in Aleppo during the Syrian Civil War.

Urban Trees Could Cut Summer Heat Deaths by a Third – Increasing tree cover to 30% could reduce premature deaths from urban heat islands by 40%. Sounds like a good idea of heath…and makes the cities more appealing too. Other actions can help too: green roofs/walls, light colored roofs/walls/landscape pavers, and replacing impervious surfaces with plants and soils.

Fresh produce contaminated with toxic BPA-like chemicals found in food labels – A Canadian study found that the chemicals migrate from labels in packaging materials into the food!

Common sweetener suppresses mouse immune system — in high doses – An artificial sweetener (sucralose) that might become a drug to reduce or replace immunosuppressive drugs that often have a lot of unpleasant side effects (if humans react to it the same as mice).

Josey Ranch – March 2023

/

I went to Josey Ranch (Carrollton, TX) in the early morning. The male grackles were posturing. The females seemed to be mostly ignoring them.

There were two Great Egrets in breeding plumage staying together as they looked for breakfast.

There seemed to be more cormorants than usual. They are probably moving northward since their breeding grounds are in the norther part of the US and into Canada.

There were a few scaups and ruddy ducks left. They too are moving northward. I don’t expect to see them in April.

I walked to the garden area between the water and the two buildings. The trees are beginning to leaf out and roses are blooming. The area was impacted by the harsher (hotter and drier) summer and it will be interesting to observe how many of the plants will regain their vigor in the upcoming months.

March is a transition month. It will be interesting to see if more of the summer birds show up when I visit in April. I always check the pond (or is it a lake?); it’s an short, easy outing and their always seems to be something new to observe.

Hagerman National Wildlife Refuge in March 2023 – Pelicans

/

The American White Pelicans migrate through Hagerman and the birds were there during my two visits in late March. The first day was sunny and breezy. Breeding adults have a plate that protrudes from the upper bill; all the birds I photographed were adults…heading to breeding grounds further north.

The birds were mostly in the water although a group were standing on a snag in the water…along with a Double-crested Cormorant (note the size difference).

I did a short video of a group feeding together. They manage to synchronize their movement…herding fish toward the shallows! It’s a pelican ballet.

The second visit was cloudy and colder…and there were not as many pelicans. The wind made the feathers stand up on the top of ther heads.

Gleanings of the Week Ending April 1, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Climate change threatens spring wildflowers by speeding up the time when trees leaf out above them – Evidently the trees and wildflowers in eastern North America are the ones getting the most out of sync.

The mystery of Alice in Wonderland syndrome (AIWS) – AIWS (or Todd’s syndrome) affects the way people perceive the world around them and can distort the way they experience their own bodies and the space it occupies. There are 40 types of visual distortions that characteristic of the syndrome. It was formally described as a distinct syndrome in 1955. Up to 30% of adolescents reported mild or transient experiences. Cough medicines and illicit hallucinogenic substances are also known to trigger it.  Sometimes medical conditions like strokes or brain tumors can cause the syndrome as can infections.

Chinook salmon fishing season canceled off coasts of Oregon, California – Dwindling numbers of Chinook salmon in the states’ largest rivers following years of drought.

In Florida, an invasive snail is helping save an endangered bird – We heard about this during a birding trip to central Florida pre-pandemic. It probably is one of the few examples when an invasive species has produced a positive outcome.

Garbage to Guts: The Slow-Churn of Plastic Waste – Lots of microplastics in the world…and they are in our food chain. Ongoing exposure decreases beneficial gut bacteria and increases pathogenic species. A lot more research needs to be done since, right now, we don’t know very much about impacts of microplastics – not just to the overall environment but to our own bodies.

 With Heat from Heat Pumps, US Energy Requirements Could Plummet By 60% - Thinking about heat….and the ‘rejected energy’ (mostly heat) in our current energy consumption. The idea is to use heat pumps to dramatically reduce ‘rejected energy’ in future energy consumption.

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms – Evidently the December 2021 - January 2022 breeding season for south polar skua, Antarctic petrel, and snow petrel was so disrupted that there were almost no young produced.

Why don’t humans have fur – Interesting…but we really don’t know. The genetic research associated with the question could have practical application for people that need to stimulate hair growth (like after chemotherapy or balding).

2021 Was A Very Good Year for Nesting Wading Birds In The Everglades – Hurray! Some good happening in the Everglades. There are so many stories about the impact of invasive species (like Burmese pythons) that this is welcome news.

Meet the sargassum belt, a 5,000-mile-long snake of seaweed circling Florida - In the open sea, sargassum can soak up carbon dioxide and serve as a critical habitat for fish, crabs, shrimp, turtles, and birds…all positive. But when sargassum gets close to shore it can smother coral reefs, alter the water’s pH…and then onshore it begins to rot within 24 hours releasing irritants like hydrogen sulfide which smells like rotten eggs or manure and can cause respiratory problems. And it often contains significant amounts of arsenic so not a great addition to a compost pile. The mass of sargassum has been increasing since 2011 --- probably in response to elevated nutrients (runoff from fertilizer, burning biomass, increasing wastewater from cities, etc.) we have released into the ocean. Sargassum has come ashore in Yucatan and Key West recently.

Nazca Pottery of Ancient Peru

/

Max Uhle’s The Nazca Pottery of Ancient Peru is included in the Proceedings of the Davenport Academy of Sciences from February 1914. The same volume includes plates with Edward K. Putnam’s The Davenport Collection of Nazca and other Peruvian Pottery; I selected two of the Nazca plates as sample images. Nazca is most famous for the lines in the plain northwest of the city of Nazca in southern Peru; seeing the pottery adds another perspective on the culture that created the drawings etched into the Earth’s surface.

Nazca Pottery of Ancient Peru

 Max Uhle was a German archaeologist who worked in Peru, Chile, Ecuador, and Bolivia in the early decades of the 20th century. Over the course of a very long career, he did field work and initiated archeological museums in South America. Most of the funding for field work came from the United States. Based on a biography by John Howland Rowe published in 1954, he spent most of his professional life in South America only returning to Germany in 1942 when Peru expelled Germans. He died in 1944.

Plant of the month - Daffodils

/

At the beginning of March – the daffodils were already blooming in Carrollton, Texas.

I was full of anticipation for daffodils at my home in Nixa, Missouri since I had planted bulbs last fall…it took another 3 week for my daffodils to open! There was a lot of cold weather all during those weeks. I did photographs over almost a week of a bud outside my office window (there is a screen on the window which make the photos ‘soft’ focus…but I find it appealing). I was worried that the flower was going to open overnight…but it was so cold that at one point (temperature in the teens) the stem bent and the bud was in the grass. Fortunately, the stem recovered and the bud opened.

I walk around on the house on a day that it was a little warmer (temperature in the 40s) and was pleasantly surprised by some daffodils in a bed that isn’t visible from any of our windows. The bulbs were planted by the previous owner. They were on the west side of the house and must have been warmed by the sun shining on the brick wall during the cold days. They were all past prime….fading frills.

And now I am hoping the other spring blooming bulbs are going to bloom too…following the daffodils.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Arctic river channels changing due to climate change – The prediction was that Arctic rivers would be destabilized by atmospheric warming…that thawing permafrost would weaken riverbanks causing faster channel changes. Using 50 years of satellite data for areas of Alaska, the Yukon and Northwest Territories (which is experiencing the sharpest atmospheric warming due to climate change), researchers have discovered that greening of the area due to warmer temperatures has caused the riverbanks to be more stable…decreasing the sideways migration of river channels by 20% in the Western Arctic!

US Energy Storage Made Record Gains Last Year – A good new story! Something I didn’t know too: “they US remains the largest demand market for energy storage in the world.”

A pool at Yellowstone is a thumping thermometer – The water vibrates…the ground shakes. The intervals between reflects the amount of energy heating the pool at the bottom and how much heat is being lost from the surface.

Awe-Inspiring Videos Show Powerful Ospreys Diving in Pursuit of Prey – Photographer Mark Smith’s Osprey pictures/videos. I saw this post and the photographer was mentioned in the composition class I was views on the same day!

Crocodiles are uniquely protected against fungal infections. This might one day help human medicine too – Crocodiles have unique defensins (components of white blood cells and mucous membranes) that are inactive at neutral pH (as in the blood) but are active in sites of infection where the pH is lower (i.e. acidic). There is a lot more research and trials between this finding and application to humans.

'All work, no independent play' cause of children's declining mental health – The reduction has happened over decades. I was surprised by the quantification: “Between 1950 and 2010, the average length of the school year in the U.S. increased by five weeks. Homework, which was once rare or nonexistent in elementary school, is now common even in kindergarten. Moreover, by 2014, the average time spent in recess (including any recess associated with the lunch period) for elementary schools was just 26.9 minutes a day, and some schools had no recess at all.”

Mesa Verde National Park has plan to save Spruce Tree House – The area has been closed since 2015 because of concerns that layers of sandstone could peel away from the arch at any time. There is a lot of work involved and the plan is current open for public comment. When we visited Mesa Verde back in 1980, it was still open to visitors. Mesa Verde is still a National Park I would like to revisit.

Toxic red tide is back in Florida – Another deterrent to making a road trip to Florida….although it appears that right now there are no red tides in the panhandle…which would be the closest destination for us…I’m thinking maybe Pensacola.

Here Are the Incredible Winners of the 2022 World Nature Photography Awards – A little eye-candy for this week. ‘Fungus Horizon’ is my favorite.

Heat pumps for every home – A good introduction to heat pumps. I want a variable speed heat pump that uses the existing ducts in my house!

Amid the High Hills

/

Sir Hugh Fraser published Amid the High Hills in 1923…100 years ago. He explains in the preface that the book is a collection of articles – some of which had been published before – and illustrated by friends. All the other books that he published (and that are available on Internet Archive) were career related (he was a British barrister and judge).  The Wikipedia biography cites no sources - is brief and unsatisfying since it doesn’t mention anything about the book except the title; I found myself reading between the lines of the book’s preface to fill in….that Sir Hugh Fraser enjoyed his vacations and friendships beyond the confines of his career that he evidently continued until his death in 1927.  The illustrations that his friends provided (pictures, sketches, photographs) are worth browsing the book; they capture the natural areas as they were in the early 1900s.

Amid the High Hills

Our Missouri Neighborhood – March 2023

/

The temperature has fluctuated wildly – from the teens to 70s this month. I took walks on two of the sunny days. We’ve had enough rain that the drainage into the ponds had running water on both days, and I stopped on the bridge to take pictures of leaves from last season in the rippling water. Oaks, maples, river birch, and red buds are represented.

There is almost always a pair of mallards about….and lots of robins.

Some branches from a magnolia in a nearby yard are upright in the pond. I wonder how long they will last…..or maybe someone is trying to root them (i.e. start new trees)?

The turtles are more active on warm days. They all appear to be red-eared sliders. Their snouts are usually all that is visible unless they are closer to shore or sunning on some high ground in the pond.

One day I started out in sunshine but there were more clouds than I anticipated. I took some landscape shots….experimenting with backlight and the curving walkway through the trees around our pond.

Some geese were on the walkway (and this time of year I give them space since they might be aggressive) so I went up to the street to complete the loop to my house. I noticed that the stormwater drain is labeled ‘no dumping – drains to river’ with a metal shield; in Maryland the labeling was painted onto the concrete.

The red maples are some of the earliest trees to bloom. The trees along the path don’t have low branches so my pictures of the flowers rely on my camera’s zoom.

Sometimes I photograph something because I didn’t anticipate it…the oak leaf stuck in the chain link of the tennis court is an example.

Another is the mats of algae on lower spillway between the two ponds. They had washed from the upper pond but are doomed to dry out on the spillway if another rain does not come soon. Still – they were ‘emerald isles’ at a time of year where there is still a lot brown in the natural world.

Fox Squirrel

/

Last time I was in Carrollton, TX, I paid more attention to the squirrels in my parents’ yard. They are a little larger than the squirrels I see in my Missouri yard and have a brownish orange underside. I realized that they are fox squirrels. I enjoyed photographing one munching on some food we had put out for the birds. The squirrel was down on the ground…up on a perch in the tree where a large limb had been removed…giving me opportunity to see it from almost every angle. I wondered if the squirrel was pregnant because it looked very rounded! Late February is a likely time the young would be born.

Gleanings of the Week Ending March 11, 2023

/

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

800-year-old hoard unearthed in northern Germany – The picture of the earrings made me wonder how they were worn…and what stones once were held in the empty enclosures.

Firewood theft: The forests where trees are going missing – Evidently it is happening around the world…maybe caused by increasing heating costs and/or other fuels not available after a disaster or during a war.

Bald Eagles aren’t fledging as many chicks due to avian influenza – Oh no! I had gotten used to seeing bald eagles frequently near where I lived in Maryland. I had assumed that I didn’t see as many in Missouri because I didn’t know where to look – but it could have been that there are fewer birds to see anywhere.

New thought on Chaco Canyon Construction – A demonstration of how the timbers for building the complex structures at Chaco Canyon could have been carried the 60 miles from where the trees grew.

Sustainable process to produce vanillin from lignin makes further progress – Making the popular flavoring agent from lignin (a waste product from the wood pulping industry) rather a chemical process using petroleum.

Quilts from the Second World War tell the stories of the Canadian women who sewed them – A little Canadian history…the spirit of giving during a stressful time…sending artful warmth. Quilts have always appealed to me because they are functional art. My great-grandmother (in the US) made wedding quilts with/for her 5 daughters in the 1930s and 1940s…and now one of my sisters is talking about quilting being something she plans to do when she retires.

More Than Half Of New US Electricity Generating Capacity In 2023 Will Be Solar – Good! Evidently California and Texas are the states adding the most solar capacity.

Archaeologists Find Elite Residences at Mexico’s Chichén Itzá – Prior to this discovery, experts didn’t know any residential structures! What they found was a complex…two houses and a palace.

Air pollution speeds bone loss from osteoporosis – A study of a diverse cohort of over 160,000 postmenopausal women. The study found that nitrogen oxides are a major contributor to bone damage and that the lumbar spine is one of the most susceptible sites to this damage. This is another reason to improve air quality!

Photography In the National Parks: Capturing Atmospheric Phenomena – Being in the right place…noticing atmospheric phenomenon…and capturing the image. It reminded me of a trip we made back in 2007 to Cumberland State Park in Kentucky where we saw a moonbow; maybe we should go again!

Elenore Plaisted Abbott Illustrations

/

I picked four books illustrated by Elenore Plaisted Abbott as the ‘books of the week.’ They are all available to browse on Internet Archive. Enjoy!

The Wild Swans, and other stories - Andersen, Hans Christian (1922)

An Old Fashioned Girl - Alcott, Louisa M. - (1911)

Alice's Adventures in Wonderland and Through the Looking Glass - Carroll, Lewis (1916)

The flower maiden and other stories - Andersen, Hans Christian (1922)

As I read the Wikipedia entry for the artist, I realized that she spent most of her professional life not far from where I traveled the last years of my career – outside Philadelphia – in Rose Valley. The area where she lived is still far less developed than where I went for work!

Cheshire Cat Moon

/

Last month when I was in Carrollton, my daughter texted that the moon, Venus, and Jupiter were visible in the west. I went out…it was a clear night…and the horizon was clear enough to see all three. I opted to take a picture of the moon since my camera could focus on it well enough to see some craters. It also reminded me of the Alice in Wonderland Cheshire Cat – where the cat’s body has disappeared and all that is left is its iconic grin.

Elm Fork Nature Preserve – February 2023

/

I arrived at the Elm Fork Nature Preserve at the same time as a Texas Master Naturalist (I could tell by his hat!) which turned out to make the walk through the circuit into a guided hike. I didn’t take as many pictures as usual. The day was brisk and sunny…pleasant in a zipped-up jacket.

Toward the back of the loop are several areas of wetlands/open water. At least one of them was an oxbow of the Elm Fork of the Trinity River – now disconnected. There were ducks, grebes, and coots…and a cormorant in a tree. They were far enough away to be almost out of range of my camera, and I didn’t take the time to get better images stabilized with my monopod.

The area was owned by the same family from 1861 until it became the preserve and was always used for household wood (shelter, cooking, eating) until it became the preserve. It is a rare parcel in this part of Texas that has always been timbered. The trees are all different sizes and I found myself taking pictures of ones that were snags or pieces of trees. When the trees leaf out it will be a good place for canopy pictures --- looking up through the trees.

A tree that had fallen across the path and been cut was particularly interesting. It had wavy markings…like meandering rivers taken from above.

There is a structure, but it doesn’t appear to have been used recently; it is beginning to deteriorate. The place does not appear to get a lot of visitors (and the Master Naturalist told me that he’d been there a few times when he thought some of the people there were not nature lovers or fishing). So – I’d like to go again but it might not be a place to go on my own.

Carrollton Yard – February 2023

/

The temperatures were getting warm enough in Carrollton TX for some of the hardy spring flowers to make an appearance.

The naked lady lilies are just leaves now…building up for their bloom during the summer. The daffodils and hyacinths are blooming.

I noticed the fallen rooster and rusting toy surrounded by brown debris from last season and the greening new growth of spring. The rooster’s fall, twisted feather and the rust on the base/foot is new this season. I didn’t attempt to right it.

The small landscapes appealed to me as well – the small rock that looks like a big cliff next to the green vegetation, the single pink flower at the base of a big mulberry tree, a red leaf surrounded by crinkled brown leaves and delicate new green growth, and a dandelion already in bloom (also at the base of a mulberry tree).

My favorite image from the February walk around the yard was a backlit dandelion seed puff.  Yes – the background is messy…but I always attempt to capture the situation as it was in nature, not something contrived.
