Josey Ranch Pocket Prairie

April 22, 2019/ Gwen Morrison

2019 04 a IMG_5743.jpg — Last week I discovered the Josey Ranch Pocket Prairie near the Carrollton (Texas) Public Library. At first it looked mostly like a sea of plants blowing in the breeze…then I began noticing the flowers.

I walked around the path slowly using the zoom on my camera to see the flowers better (and photograph them). There were a lot to see. Some I recognized – the bluebonnets, Indian blanket, Indian paint brush, and pink evening primrose. Others I didn’t. I’ll have to go back and get more detailed pictures to identify them. Spring is a great time to see wildflowers!

I’ll have to remember to take a turn around this pocket prairie when I come to Carrollton in the summer and fall…see it in difference seasons. There seems to be a group of volunteers maintaining the area. There were piles of some invasive plants that had been pulled out and were ready for pickup. The rain garden area seemed almost new. If it rains while I am here – I’ll go over in my rain gear to see how it works!

A Carrollton Garden – Part II

April 21, 2019/ Gwen Morrison

It’s been more than 8 years since my grandmother died – but there are still many plants in the garden at my parents’ house that she started. The pink preference sage all came from a plant from her sister’s garden.

The oxalis was something she saw first in her sister’s garden then ordered some from a catalog (we think). It is growing so profusely these days that some of the plants are being potted to be part of the floral decorations for my niece’s wedding.

The bees like the flowers too.

The evening primrose is self-propagating around a rose bush my grandmother got as a birthday present (the rose bush must be over 20 years old now) and she planted the primrose seeds at its base.

I’m not sure where the daisy-like flowers came from, but they’ve been in the garden for a long time. These days they bloom in enlarging clumps in the front yard garden under the big mulberry and beside the red yucca.

The continuity of plants – passed between family members and through generations. Remembering her…in her garden.

A Carrollton Garden – Part I

April 19, 2019/ Gwen Morrison

I am visiting my parents this week in Carrollton TX and their garden is responding to the warmer weather. Mounds of oxalis line the large patio – carpeting the partial shade area under the mulberry trees.

Various kinds of iris are in bloom. The Dutch iris blooms seem to last longer than the other kinds.

The mulberry trees are a fruitless variety. The trunks of the largest trees have a lot of color when they are wet. Most of the trees have small branches emerging along the big branches. The larger branches have been thinned to allow more sunlight to reach the ground so all the little branches that are within reach of the pole clippers are snipped from the trees keep the canopy open.

The pecan tree is finally old enough to bloom and may produce some pecans this year. Hopefully the nuts will be the paper-shell variety.

The red yuccas are not blooming yet but the seed pods from last fall are still on the stalks. Some of them look almost black (like they were burned). I like the shapes of the empty pods.

More pictures from the garden tomorrow.

Up Close Irises

April 16, 2019/ Gwen Morrison

There was a large vase of irises from the garden to welcome us to my parents’ house last week. Over the course of the evening, I took several opportunities to photograph them at close range – with and without the macro lens. I like the curves of all parts of the flower - from bud to full flower to spent flower. Today - savor the color and shapes of irises!

Belmont – April 2019

April 15, 2019/ Gwen Morrison

The Howard County Conservancy spring field trips at Belmont and Mt. Pleasant are into prime time. The two I volunteered for last week had beautiful weather for hiking – almost perfect temperature and dry. I always arrive more than 30 minutes before the students. It’s a short walk from parking to the Carriage House….long enough to get some pictures. Birds that are around: chipping sparrows, robins, and red winging blackbirds. There is at least one resident mockingbird which I heard but didn’t get a picture.

The warmer weather is also causing things to bloom and new spring green leaves to unfurl.

As I wait for the bus, I take pictures toward the manor house, down the entrance road, and down toward the pond. It’s the calm….before the students arrive.

2019 04 IMG_3992.jpg — The students, teachers, and chaperones come on buses and there is a flurry of activity to get the groups sorted into hiking groups and activity groups.

The hikes are about an hour. There are forest and meadows…lot of opportunity for good observations. One of my hiking groups was making BioBlitz observations…documenting a common blue violet blooming in the middle of the mowed path!

Glimpses of Providence

April 12, 2019/ Gwen Morrison

My class was on the 17th floor of the hotel. The classroom and break room had windows in all directions from the hotel offering views of the state capital and Brown university…a park with a skating rink and wind turbines. I even took a picture of part of the hotel façade! Most of the pictures I took were in the morning. One morning the bare trees in a little park were highlighted – maybe my favorite cityscape of this group.

On the last day, I walked by the park (near the skating rink) and realized it was more unique than I has realized from the high window. The playground had nets and cables…not the usual playground equipment. What a fun place in the city – but there was no one there as I walked by on a cold morning. It would be busy in the afternoon probably. I’d seen people there from the window earlier in the week.

Overall – Providence has a welcoming city center. It is clean and walkable. I liked it and will have to go back when I have more time to wonder around.

A Student Again

April 11, 2019/ Gwen Morrison

The paper coasters and pencils in my room at the Biltmore Providence had the slogan ‘we are all students’ and it fit the week for me. I loved being a student. The middle two days (of the 4 day class) were intense and I was very ready to sleep by the end of the day. I woke up at my usual early time each day and saw the sunrise from the hotel room.

Over the course of the class, we created 24 Zentangle® tiles which eventually were attached inside our student journal.

My favorite tile creation of the week was a voice guided Zentangle meditation – not just the tile itself (I like all the tiles I create) but the way it was done. There was none of the usual visual demonstration of the pattern. It requires a lot more descriptive language from the instructor…and good listening skills from the students. I’m not confident that all patterns could be learned in this kind of session – but it was very easy to slip into meditation with this presentation of the Zentangle Method. The mosaic we made afterward (a tile from each student created during the voice guided session) had even more variety than other tiles from the class.

Here is the one I created. I photographed it after I retrieved it from the mosaic and put it into my journal.

The Zentangle® Method is an easy-to-learn, relaxing, and fun way to create beautiful images by drawing structured patterns. It was created by Rick Roberts and Maria Thomas. "Zentangle" is a registered trademark of Zentangle, Inc. Learn more at zentangle.com.

Biltmore Providence

April 10, 2019/ Gwen Morrison

I started seeing patterns in lots of places in the hotel. In the room, it was the wallpaper on the upper part of the bathroom walls (shells with sparkle), the bathroom floor tiles, and the carpet.

On the floor where the class was held (ballroom and snack area) there were fixtures and fabrics…some the original vintage of the hotel and some very recent. I felt I was immersed in a pattern rich place – but there are many places that turn out to be pattern rich when we look closely.

On the Train to Providence…and Home Again

April 09, 2019/ Gwen Morrison

Last week, I went to the Certified Zentangle® Trainer (CZT) class in Providence RI. I decided to take the train since the hotel in Providence was within walking distance of the train station…and I had never taken more than a day trip on the train. The class started in late afternoon and the train from the Baltimore Washington International Airport train station was about 7 hours. I left in the early morning. It was a little daunting when my husband dropped me off in the dark at a station under construction (or renovation…not sure…most of it was not open). I was glad it was not a cold morning. There were no Amtrak personnel around that I noticed but there were enough experienced train riders to reassure me that I was in the right place. I also learned about the quiet car…what luxury. The sunrise (blur) happened not long after the trek began.

The gentle rocking of the train and the quiet was very calming…so different than an airport. The seats were larger than an airplane seat – and therefore more comfortable. Overall everything was roomier than an airplane. There was never a wait for a bathroom. A lot of people got off at New York and I moved to a window seat – still in the quiet car. I tried taking some pictures from the train window. Many of the views were of cities (construction, debris and trash, industrial areas) and forests.

As I got off the train in Providence, my seatmate – a native of Providence - pointed me in the right direction for the hotel and Google maps on my phone picked up the directions shortly after I started walking. It was gently downhill! I realized that several days later it would have to maneuver up the hill.

That is what happened on the morning I left. I got some ‘active minutes’ on the walk to the train station and took more pictures as I got tired – crossing the Providence River

And the landscaping in front of the train station. The landscaping seemed new and I wondered how long it had been since the station has been renovated. Hopefully the one at BWI will be improved by the construction that is happening now.

The station in Providence was closer to what I expected – a large indoor area where there were wooden benches (like pews) for sitting around an open area…some places to get food. My train did not leave until almost 9. There were marques that were like ones in airports that directed people to the right track a little before the train arrived. I took the elevator down rather than the stairs since I had luggage that was OK rolling…but not carrying.

And then I was on the train for 7 hours – enjoying a good book and journaling the events of the week. Overall the train was a good experience and I found myself wishing that it was possible to take trains to more places I travel.

More posts about my Providence experience in the next few days…

US National Arboretum in Early Spring

April 07, 2019/ Gwen Morrison

Last weekend we went to the US National Arboretum to see cherry blossoms. We entered the New York Avenue Gate and parked in the big lot just inside….with cherry trees in sight. We walked over to the trees. I got side tracked by some golden moss with spore capsules…had to take pictures from overhead and then from ground level. It was growing under the cherry trees.

2019 03 IMG_5483.jpg — The days before we went had been windy and I found some blooms on the ground – little jewels in the dried leaves and moss.

I zoomed to get some close-up pictures of flowers on the trees – all shades of pink to white.

As I took some pictures of the high branches of one tree, I noticed a lot of bees. I was photographing hand held so had to be content with just knowing the dots in the pictures were insects!

We got back in the car and continued further into the arboretum. There were a lot of cars parking along the side of the road and we could see trees that were blooming ahead. We thought maybe it was more cherry trees. But no – it was deciduous magnolias! They were probably at their peak and gorgeous. People where photographing young children under the trees and held up next to the flowers. There were several different kinds of deciduous magnolias in bloom. My favorites were the deepest pink ones that I saw at the very beginning.

I zoomed in on two buds. Note that the outer covering is very fuzzy. Then there is a covering that looks like brown paper….and then the petals.

Evergreen (southern) magnolias are in the grove as well. They will be beautiful this summer. Right now, the empty pods from last summer are dried (on the tree or the ground under it) – and a study of complexity. I didn’t see a single red seed that had survived the winter in a pod!

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.

BBC - Future - What happens when we run out of food? – Even in the US, nearly 12% of households re classed as being food insecure; more than 6.5 million children go without adequate food. And the whole food system can be disrupted very easily by war and very bad government all around the world.

Refugee women have healthier pregnancies than US women -- why? An unhealthy US culture: For African refugee women, acculturation may negatively impact health -- ScienceDaily – I was surprised that the researchers did not explore the idea that maybe the value of early pre-natal care is overrated for people that are generally healthy when they get pregnant since the refugee women tended to not start pre-natal care until their 2nd trimester.

Top 25 Wild Bird Photographs of the Week: Migration – National Geographic Society - Birds are migrating through our area…we’re seeing more robins…and the juncos will leave soon to go further north. These pictures feature birds from around the world…that are migrating.

Hospital disinfectants should be regulated like antibiotics new study suggests – It’s not just antibiotics that drive antimicrobial resistance…it’s disinfectants (particularly in hospitals) too.

BBC - Future - The unexpected magic of mushrooms – New items made from fungus...replacing some kinds of plastics. It’s good that fungi are so plentiful on the planet – exceeding the biomass of all animals.

An Island Apart – Acadia National Park’s Isle ad Haut. A very different experience from Mount Desert Island

Beautiful cherry blossoms photos – Our cherry tree is in bloom right now. I guess cherry trees are enjoyed around the world very year about this time. There is a picture of the cherry trees around the tidal basin in Washington DC included in the pictures.

Green tea cuts obesity, health risks in mice: Follow-up study in people underway -- ScienceDaily – More research needed…. but I am enjoying green tea already (my favorite is a blend with mint).

Make A Home for Wildlife – Cool Green Science – Some ideas for creating an oasis for wildlife --- it doesn’t take much to help pollinators or birds!

Why did Flamingos flock to Mumbai in record numbers this winter? – 120,000 flamingoes…that’s a lot of birds!

Patuxent Research Refuge

April 05, 2019/ Gwen Morrison

I attended the Patuxent River Conference last week. The conference was informative – lots of up-to-date information about the river. One of the branches of the river (the Middle Patuxent) is through the forest – downhill – from my house. The conference venue was the Patuxent Research Refuge and there was opportunity to look around the visitor center and onto a nearby trail. It has been awhile since I had visited the place and the visitor center was in better condition that I remembered.

The displays in the visitor center had been updated. The one I found most poignant was the whopping crane display. The Patuxent Research Refuge tried for years to raise whooping cranes to establish a new migratory flock but this year the effort was stopped. The whopping crane we saw down in Florida during the Space Coast Birding and Wildlife Festival (see my post here) began its life at this refuge.

During the morning break – a mockingbird sat in a nearby tree. It had quite a repertoire of songs.

I remember the timber wolf sculpture in front of the visitor center but the colorful screening on the front windows of the visitor center was new to me.

The refuge biologist let a hike during the last session of the day. A prescribed burn had been done on some of the areas around the visitor center to clear out biomass…keep the area grassland habitat rather than forest.

We hiked over the causeway and into the forest. The Refuge is doing an inventory of the forest trees and taking core samples to determine the age. One of the corers got stuck in an oak and they are still trying to get it out!

The trees are not leafed out…but some are easy to identify. Beech trees are easy any time of year.

A lot of the pines at the refuge were planted about the same time and are dying off together too. There are quite a few that have fallen over. But there are still a lot of trees that fill in the canopy. This will be a very shady area when the trees leaf out.

It was a good day for a conference and a visit to the refuge!

100 Desert Wildflowers in Natural Color

April 04, 2019/ Gwen Morrison

Dodge, Natt N. 100 Desert Wildflowers in Natural Color. Southwest Monuments Association. 1963. Available from the Project Gutenberg here.

Natt Noyes Dodge (1900-1982) was the regional naturalist for the Southwest Region of the National Park Service from 1935 to 1963. He was also an author and photographer – both of which are shown in this book along with his knowledge of the region. The version available from Project Gutenberg is from the third printing in 1967 which was a revision from the original in 1963.

I’m glad that the copyright holder has allowed this book to be available online....easy to enjoy the photos of desert wildflowers.

I had bought several of Dodge’s books is national parks when traveling to New Mexico, Arizona and Colorado from our home in Dallas in the 1970s, but I didn’t have this one.

Texas Wildflowers in Natural Colors

April 03, 2019/ Gwen Morrison

Whitehouse, Eula. Texas Wildflowers in Natural Colors. 1936. Available from Project Gutenberg here.

This was my favorite botanical book for March….and maybe beyond that too. Eula Whitehouse lived from 1892-1974 and spent the latter part of her career in Dallas – working at Southern Methodist University from 1946 until her retirement; her books and collections are the core of what became BRIT (Botanical Research Institute of Texas). She assisted in organizing the Dallas County Audubon Society in 1954.

The book was self-published first in 1936 and remains a favorite among many Texas botanists. It was published privately and distributed through the Texas Book Store in Austin and then, in 1948, through Cokesbury Bookstore in Dallas. The version available online at Project Gutenberg shows both dates. I’ve included a few sample images below.

I grew up in Texas and found myself wondering why the nature day camps I attended during my elementary and middle school summers didn’t use her book as a reference as we tried to learn about the wildflowers we saw around us.

Eula Whitehouse published a study on the evolution, or succession, of plant communities at Enchanted Rock (in Texas) as part of her doctoral research at the University of Texas in the 1930s. In the late 1970s, Lady Bird Johnson urged The Nature Conservancy to purchase Enchanted Rock to be set aside for posterity. I like that there is a linkage via Enchanted Rock between Eula Whitehouse and Lady Bird Johnson – two women that were deeply involved in preserving wildflowers of Texas.

For more information about Eula Whitehouse, see pages at BRIT and Texas State Historical Association.

Conowingo – March 2019

March 31, 2019/ Gwen Morrison

My husband and I made the trek up to Conowingo Dam last weekend. The water was high and laden with silt (although not quite as high as the last time we were there).

The trip was a success as soon as we got there: a bald eagle was preening in a tree next to the parking lot. I took some traditional portraits.

Then I zoomed in on the talons.

At one point the eagle did a little dance on the branch (watch the feet)!

One of the other photographers told me about the nest up in the right tower across the river from the wharf where we were. It is on the narrow platform below the top of the tower. I zoomed in and saw sticks that are probably one side of the nest but no birds coming or going.

There were cormorants fishing in the rapidly moving water although I didn’t see any successful catches.

I did manage a sequence of a cormorant flying low over the water.

Overall it was a good spring outing – warm enough that we didn’t need out coats!

What oil leaves behind in 2.5 billion gallons of water every day in US -- ScienceDaily – Wouldn’t it be nice to not have oil polluted water injected underground…and sometimes into aquafers? Water is already in short supply in some areas of the country (mostly in the west). We need technologies to never contaminate water in a way that it cannot be consumed by plants and animals…and ourselves.

In Germany, Consumers Embrace a Shift to Home Batteries - Yale E360 – Half of the orders for rooftop solar panels are sold with a battery storage system too in Germany. I wonder when the US will catch up.

Butterfly numbers down by two thirds: High-intensity agriculture reduces number of butterfly species in adjacent areas -- ScienceDaily – It’s not just butterfly numbers that are down either. Agriculture research needs to hone practices that are productive in the short term…and the long term. In other words – all agriculture needs to become sustainable for humanity and the rest of the organisms that inhabit the Earth.

Nitrogen pollution's path to streams weaves through more forests (and faster) than suspected -- ScienceDaily – Nitrate is one of the abiotic tests we do for water quality assessment with high school students. This is a new finding to think about and incorporate in to the analysis of readings after heavy rains. The nitrogen might be moving so fast that the forest can’t absorb it!

Missouri Making Hyperloop Plans - News | Planetizen – A hyperloop between Kansas City and St. Louis! What a boon to the two cities and probably easier to build since there is not the heavy population between the two cities like the route that was originally talked about in California.

China Isn't Recycling Tons of U.S. Plastic Trash Anymore: Goats and Soda: NPR – We’re going to have to show some innovation in dealing with plastics – mostly single use – that we dutifully put in our recycle bins and assumed they would be recycled. Now a lot of them are going to landfills or polluting our waterways. With a little thought, my family has reduced some….but the next step is tough. Some products we need are only available packaged in plastic.

Mt. Pleasant – March 2019

March 25, 2019/ Gwen Morrison

I was at Howard County Conservancy’s Mt. Pleasant on a sunny cold morning last week – and took a few pictures. There were two things that have always been there and almost always on my walk from parking to the nature center that I don’t think I have photographed before: 1) The old tractor that has been in the same place for so long that it is sinking into the soil under it (or silt is running down the slope to the wagon shed and accumulating around the tires).

2) The hook closure on the blacksmith’s shed….probably made by the blacksmith!

The flowerpot people were dressed for spring…but looked a little bedraggled. The March winds have probably made some adjustments.

I took a picture of a pine on the way to a stop in the Honors Garden. The pines are still the main greenery around.

In the Honors Garden, the sun was highlighting last season’s cone flower seedpods.

But the reason I was in the Honors Garden was to check out the little pond. As I walked up a frog swam rapidly through the water to a new hiding place. It was too cold for a lot more activity.

This little pond is a favorite of the local Wood Frogs and they have been busy. There were egg masses in the water….soon to be tadpoles if they are not too far out of the water and freeze before they can develop. I posted about the frogs here back in March 2016….but it was a warmer day and I noticed the frogs more than the eggs.

I continued to the Nature Center for the training session scheduled for the day.

Salt Could Play a Role in Allergies | The Scientist Magazine® - Atopic dermatitis has increased more than 2-fold since the 1970s….and researchers do not attribute the increase to greater awareness or diagnosis. Now comes the observation that people with lesioned skin from atopic dermatitis (but not psoriasis) had a 30-fold higher salt level in their lesions than in their unlesioned skin or skin from healthy controls. The connection to diet is speculative at this point…but we do have higher salt in our diet now that most people had in the 1970s.

In Siberia, Toxic Black Snow Reveals the Toll of Coal Mining | Smart News | Smithsonian – Yuck! Pollutions from open-air coal pits…in the extreme. Another reason, I’m glad we’re moving away from coal powered electricity generation. I wondered if the people living in the area of black snow develop terrible lung problems.

Piling Up: How China’s Ban on Importing Waste Has Stalled Global Recycling - Yale E360 – China’s plastic imports have plummeted by 99%, mixed paper has dropped by a 33%. Recycled aluminum and glass are less affected by the ban. So now we are sending plastics to landfills, incinerators or littering the environment. Communities across the US have curtailed or halted their recycling programs. That hasn’t happened (yet) where I live in Maryland. We must learn to produce less recycle (waste) and process it more locally…not ship is someplace else in the world.

Prehistoric Microbes Inhabit an Oasis in the Northern Mexican Desert | The Scientist Magazine® - Fish, diatoms, and bacteria in lagoons in the Chihuahua Desert and cannot be found anywhere else on Earth. More than 5,000 species of bacteria and archaea have been documented.

Owls against owls in a challenge for survival: Researchers forecast interactions between two owl species and the quality of their habitat in the Pacific Northwest -- ScienceDaily – I learned at the Festival of the Cranes (New Mexico) last fall about Barred Owls moving into Northern Spotted Owl (NSO) territory….and winning the competition. That further reduces the NSO populations which is already endangered because of over-logging of the old growth forests.
