Ginkgo Grace

I like ginkgo trees  – the way the trees grow…the shape of the leaves and the way they move in the breeze (I’ve heard that their fruit is stinky but have never been around a tree that had fruit). There is a tree in the picnic area of Howard County Conservancy’s Mt. Pleasant Farm that I’ve photographed several times over the past few weeks; I’m sharing my two favorite images – perhaps of the same branch.

The first day was very cloudy. The leaves are in silhouette against  gray sky…but there are water droplets which make it not quite a simply silhouette.

The second one was on a brighter day. I like the color of the sky behind the silhouetted leaves. The leaves had another week or so to mature making the characteristic ginkgo shape more obvious.

I think I like the one with water droplets best.

Gleanings of the Week Ending May 20, 2017

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.

Million-Dollar Prize Hints at How Machine Learning May Someday Spot Cancer – Hopefully this type of technology will reduce the number of false positives that have been so common as we’ve used advanced imaging to find cancer (too many times when biopsies have been done and it has not been cancer). Note that the winning team was from a Chinese university. No country – even the US – can rest on past innovation for their future.

How farmers put apples into suspended animation – 9 in 10 apples bought in the US are grown in the US. This article talks about how apples are stored so that we have them throughout the year rather than just in the fall.

Frosty Monarchs – This was a post from earlier in May…but it has great picture of the milkweed egg. We had some cooler temperatures here in Maryland after the milkweed came up; there was frost on the rooftops but the it must not have gotten to freezing at ground level since the milkweed was unscathed.

Antarctica’s Blood Falls Helps Unravel the Inner Workings of Glaciers – Briny water flows (i.e. in liquid form) flows under the ice of the glacier!

Golden years are longer and healthier for those in good health in middle age – When I read the headline, my first question was - what did they define as “middle age”? The answer was ages 40-59. It was a 40 year study with 18,714 participants. It makes the point that living healthy in mid-life is important to health later in life.

It’s Raining Blood and Feathers: Catching the Spring Raptor Show – There is so much going on in the spring…and it not just flowers and song birds.

Dragons on the Hunt – Komodo dragons bring down a water buffalo. (5-minute video)

Cost of Zika outbreak in the United States could be high – There is a lot of complexity….but even assuming a lower incidence rate that has been observed in other parts of the world and that only the southern tier of the US would be impacted…still results in high costs. Prevention costs money and treatment even more. The range from the models is $183 million to $1.2 billion. Another article on the broader topic of mosquito-borne illnesses: Researchers analyze what a warming planet means for mosquito-borne illnesses.

The Art of Botanical Illustration, Scientific Botany – Some of these botanists/artists I have found before…I’m going to check what Internet Archive and Hathi Trust have in their scanned collections for each of them.

Serene Photos Highlight the Tranquil Beauty of 100 Japanese Gardens – Eye candy…even better if you have a garden near you to visit.

Brookside Gardens after a Rain

Before and after our session with the butterflies in the conservatory last week, I took short walks around a very wet Brookside Gardens. The stream near the entrance was flowing over boulders that have been added in past few years to control erosion. I took a picture up and down stream from the bridge. The vegetation has increased dramatically over the past month.

A squirrel enjoyed a nut on a low pine branch.

The old water garden has matured into a rain garden. I like the low growing plants spilling over the rocks.

The winds had blown a small branch of leaves out of a tulip poplar tree and into the parking lot.

There were wildflowers blooming along the boardwalk between the conservatory and the nature center.

My favorites were the Jack-in-the-Pulpit

And the columbine.

There were some very wet mushrooms growing on an injured tree trunk…covered with slugs.

Many of the ferns were already unfurled but there was a fiddlehead and unfurling frond that I couldn’t resist photographing.

There were some very wet irises in one of the formal gardens

But I liked the red poppies more.

Monarch Caterpillars Saga I

Last weekend, my husband commented that we had milkweed coming up in our front flowerbed (milkweed plants circled in white in the picture below) and I needed to cut it down. Once milkweed is established it comes up year after year from the roots.

I decided to check for Monarch caterpillars on the plants first. Sure enough – I found caterpillars. The first one I found was tiny. I almost didn’t see it. It was less than a quarter of an inch long!

The other two were a little further along. The yellow, black and white stripes typical of Monarch caterpillars were more evident.

I decided I would try raising the caterpillars in an old fish tank that was previously gathering dust in our basement. I’ve cleaned it up and purchased the netting to cover the top. My next post will be about my adventure cutting the milkweed with the caterpillars on it and setting up my Monarch caterpillar nursery. I have plenty of milkweed to nourish the caterpillars until they make their chrysalis. When they hatch – I’ll release the butterflies near a good patch of milkweed so they can lay more eggs and continue their northward journey.

Mayapples

The mayapples were blooming at the Howard County Conservancy’s Mt. Pleasant Farm last week. The stand I photographed is down near the beach area of the Davis Branch. It was one of those instances where it was good to have my cell phone along so that I could take pictures while I waited for the middle schoolers to show up for their stream assessment work. From above – the flowers are not visible at all. Walking down the slope and then looking back help make the flowers more visible. The leaves are an umbrella over the flowers!

I took some closeups of the flowers by walking back up the hill and bending over to get the camera under the leaves and close to the flowers.

They are one of the larger wildflowers but one must know to look under the leaves! They bloom in May and the ‘apple’ forms during the summer. They are not edible.

Glowing Tulip Poplar Flowers

The tulip poplars in the forest behind our house are blooming.

On a sunny day last week, I walk our closer to the trees at mid-day and took zoomed pictures looking up in the tree. Because the sun was almost directly overhead the flowers seemed to catch the light and glowed among the greenery of the tree’s leaves.

The shape of the flowers is very tulip-like but the coloring is quite different. The inside of the flower is different too.

I think these are my favorite pictures to date of this tree in the springtime.

Conowingo – May 2017

We had more success at Conowingo in May than we did back in April although we first got there – all I saw were cormorants in the water.

There were no vultures on the high reaches of the dam or birds sitting on the big towers.  It was very windy and I eventually started looking lower on the rocks across the river from our vantage point. It’s a little far away for pictures…but that’s where the birds were. The first group I saw included a Great Blue Heron and some pigeons (the pigeons are usually all over the dam but seemed to prefer the rocks on the windy day).

I started taking pictures of all the rocks. How many eagles do you see in this pictures (remember the immature eagles don’t have white heads and tail feather yet)?

I count 7 Bald Eagles…and a Great Blue Heron and a Cormorant.

Eventually I saw an eagle on one of the towers

And then thought to zoom in to the platform of the tower after remembering someone commenting last month that there was a nest on one of the towers. Sure enough – it looks like there is. Hopefully no one will have to go up there until the eagles are done with the nest for the season.

I took a few none bird pictures as well. This spider web was somewhat damaged by the wind but I was pleased my camera would focus on it. The spider jumped from the web to me while it got the picture! Fortunately, I noticed and managed to get the critter to the ground somewhat close to the web.

I photographed the flowers of the Princess Tree that is growing on the cliff that is across the parking lot from the bird viewing area. These invasive trees are easy to spot this time of year because of the color of the flowers. They grow very fast….and the seeds are dispersed so I seem to see more of them every year.

Ten Little Celebrations – April 2017

It’s spring…and there is a lot to celebrate.

Second graders coming to Mt. Pleasant for the Science of Soil field trip. I’ve done two file trips for them so far and both have been a lot of fun – using the soil auger in several places while we hike, talking about rocks looking at the old rock wall dividing the fields, seeing how the stream restoration work done during the winter is greening up and full of puddles after a rain.

Azaleas. There are some in our neighborhood but making the trek to the Brighton Dam Azalea Garden is the day we celebrate the profusion of blooms and colors.

Pre-schoolers on a Nature Tales field trip. I’ve done three of the pre-school field trips at Belmont in April: two that were rainy days and one that we made it to the forest. I’m learning how to keep the younger children listening and participating for the whole 20-30 minutes I have them. There are so many little celebrations in every session because the children are so enthralled with the new things they are seeing and doing….I can’t help be celebrate with them.

Delmarva birding. My husband and I spend a day at the Delmarva Birding Weekend late last week. It was our first time to attend and we enjoyed it. I celebrated that there were so many birds to see (and photograph) not that far from where we live. I’ll be posting more about our experience in the coming days.

Faromir. One of our cats died in April. We celebrated his life…and that he was will us for 13.5 years. He was my husband’s little buddy.

Favorite lipstick available again. I’ve always liked Cover Girl Bronze Glow lipstick and was very disappointed when I couldn’t find it anywhere…but now it is back. I celebrated that Cover Girl has started making it again.

Fitting into smaller jeans. I discovered that I can fit into some jeans that I thought were too small. That’s always something I’ll celebrate. I also celebrated that I hadn’t put them in the giveaway pile last fall.

New blade for old paper cutter. I was thrilled to find a new blade for my 20-year-old rotary paper cutter. When I couldn’t find the replacements in a local store and the new cutters did not look at all like mine, I thought I was going to have to buy a new one….but Amazon had the size I needed.

Roman Art and Archaeology course from University of Arizona. I’m not taking as many course from Coursera as I’ve gotten busy with other things…the few I’ve taken recently have been fabulous. I celebrate the availability of the course as the perfect time (the lull before the ramp up of spring field trips) and the well done videos and other references.

Boxes of old documents shredded. We’ve cleaned out some old boxes full of paper (spring cleaning!) and took 2 to be shredded at a local shredding event. I celebrated getting all that old paper with account numbers and social security numbers securely recycled.

Photographs through my Office Window – April 2017

There has been a lot of activity through my office window this month. The squirrels are feasting on the tender samaras in the maple – early in the month

And then a couple of weeks later when the leaves are unfurling.

The squirrels have a pathway around our yard via trees and fence…rarely on the ground.

The robins are around but don’t seem as numerous as previous years.

We now have two kinds of sparrows: chipping sparrows and

White throated sparrows (with the dash of yellow above their eye).

The blue jays are still frequent visitors to the bird bath.

I haven’t seen a lot of grackles but there was one that visited our yard long enough for a picture.

We have a pair of cardinals again this year – probably nesting nearby.

Mourning doves like the birdbath and the roof line of our covered deck. This one seemed to want its picture taken!

Zooming – April 2017

What a difference between March and April! The collection of zoomed images this month is dominated by flowers: Tulips with sunshine through their petals and patterned centers,

Wild flowers on the forest floor,

And trees with flowers like Dogwoods,

Tulip poplars, and

Carnation tree (a type of cherry) petals carpeting the sidewalk after a rain (when it dried out, a little boy on a walk with his mom had great fun scooping up the petals and throwing them in the air like confetti!).

Of course, there were a few other scenes where the zoom on my camera was appreciated: Canadian geese on an island in Centennial Lake (Do you see the one asleep on the nest keeping the eggs warm?),

The occasional early insect,

And the quivering of the water in the overflowing bird bath during a light rain (taken from my open front door so that I wasn’t out in the rain).

Dogwoods and Jack-in-the-Pulpits at Brighton Dam Azalea Garden

Azaleas are not the only plants I look for at Brighton Dam Azalea Garden. The dogwoods and jack-in-the-pulpits are blooms at the same time. The dogwoods are understory trees. The older ones that are the understory to the big oaks and tulip poplars are native dogwoods – white with notches on the outer edged of the ‘petals’.

Newer hybrid dogwoods are planted in the same area as the new hybrid azaleas in an area to the left of the garden entrance. There are white ones – without a notch…and pink ones. They are easier to photograph because the trees are smaller and more flowers are at eye level.

Jack-in-the-Pulpits are harder to notice because the flowers are almost the same color as the leaves. See if you can see the flowers before scrolling down to see more enlarged views. One of the enlarged views has a lot of aphids (yellow).

Young Oaks at Brighton Dam Azalea Garden

There lots of big oak and tulip poplar trees at Brighton Dam Azalea Garden that provide the dappled environment that azaleas need. The surprise for me this time was the large number of smaller oak trees. There must have been a large crop of acorns in the past few years that the squirrels planted and forgot and the result were a group of foot high oaks with tehri leaves unfurling. The leaves of one were still wrinkled and red.

Another was a little further along and the leaves are looking more like oak leaves (red oak probably).

I wish there was a stand of young oaks like this to show the pre-schoolers when they come for a Nature Tales field trip and we talk about the life cycle trees.

The is such a great time of year to see how trees come bare from the bare branches of winter – and the small trees are much easier to observe than the giant trees with their branches so far above eye level.

There is an art like quality to the unfurling of leaves as well…I could resist these very young leaves emerging from the bud.

Azaleas!

We visited Brighton Dam Azalea Garden yesterday morning. it was the perfect day to go: cool (not cold) and dry (the day before was rainy and the forecast for the day following was for more rain). We were early enough that it was not crowded. The garden is near the dam that creates the Triadelphia Reservoir between Howard and Montgomery Counties in Maryland. I read an article from back in March that said the lake was at 49% of capacity because of a drought over the past 6 months for our part of Maryland.  Looking past this grouping of azaleas, it’s obvious that the lake is low.

The azaleas are underneath large trees – with a few understory dogwoods. I experimented with the ‘fisheye’ setting on my camera for this shot.

The most prevalent colors of azaleas are pink, white and red/magenta…with a few light purple mixed in.

The pink ones seemed to draw my attention the most. Many of them had water droplets on them.

The magenta color almost gets too intense!

There are some newer plantings that are recent hybrids that are orange-yellow. The flowers are clumped and even the buds are worth a closer look.

But my favorite picture of the azaleas was of white flowers. What’s not to like about white flowers with water droplets and a black background!

Tomorrow I’ll share some images of oak seedlings that were coming up in the garden.

Earth Day in Howard County, Maryland

We had a very cloudy and wet Earth Day yesterday. It was a little cool too. But the azaleas are beginning to bloom and

The day lily foliage is very green around the birdbath beside by front porch. We’re behind on rain this year so getting some is a good thing.

I headed out to the local GreenFest after lunch – noticing a dogwood in bloom on my walk to the building.

The part of the event to be held outside was impacted by the rain (for example, no solar telescopes) but there were plenty of vendors inside the Galleria building of the local community college and an orderly crown moving around the exhibits. I volunteered at the Howard Country Conservancy’s table for a couple of hours. I sauntered around the other exhibits before my ‘shift.’ One group was giving away burr oak saplings….but my yard is not big enough for that tree (with a red oak already holding a big part of the front yard and the back a forest with tulip poplars, red maple, and black walnut! I refrained from picking up any more reusable bags too since I already have more than I can use. I did pick up a sunflower seed in a tiny watering can. I’ll plant it in my front flower bed!

There were competing events for the day – tree planting and March for Science. 2017 was a crowded Earth Day (for a crowded planet).

Gone to Seed

The first dandelion flowers have already gone to seed. I notice many along the sides of the narrow county roads…and in the plants I photographed earlier on my deck. The plants move from flower to seeds in about a week.

And then the seeds are ready to float away and sprout in any bit of soil that is deep enough for their roots.

These plants that we fight as weeds in our lawns were brought to North America as a desirable garden plant by early colonialists! The leaves and flowers are edible…there is dandelion wine. I try to remember that as I photograph them.

Preserving Spring

When I used twigs to show pre-schoolers about how the tree buds and seeds looked during the spring…it occurred to me that it would be good to have those items to show for more than just the early spring. I decided to enclose some of them in clear contact paper. Maybe the plastic would seal off enough air to keep the plant material from deteriorating…and it would not require the heat of a laminator. The red maple samaras were my first experiment. The seed part of the wings bulge a bit, causing a little bubble. As I looked more closely after I’d finished encasing them front and back with the contact paper, I realize there are still remnants of the flower (red) where the seed is connected to the small stem.

My next attempt was with sycamore leaves that had unfurled from the branch I put in water after I cut it when it has enlarged buds.  I got several sizes of leaves from the buds that split open and have leaves unfurling now (see my previous post about from a few days ago).  The smallest ones are the size of a finger nail. The clear contact paper on both sides makes it possible to view both sides of the little leaves and to notice that one is still curled – not quite unfurled from how it was packaged in the bud.

I had some sycamore leaves from last summer that I had pressed in a book. I used the contact paper with them too. They are very dry and fragile at this point but the contact paper may stabilize them. The leaves are the size of my hand or larger. One of the them had lots of holes in it….so would be good to reinforce that trees are food and home for other creatures.

Next time I am a volunteer naturalist talking about trees….I’ll see if they survive!

Invasives on the Deck

I left some pots on the uncovered part of our deck from last summer…intending to plant flowers for pollinators in them for the upcoming season…but I have invasives pull the first! One pot has a very health garlic mustard plant (there is more of it at the edge of our forest. I’m pulling all of it that is on our property. I supposed some people might like it in salads….but it is too aggressive in places I want jack-in-the-pulpits and woodland wildflowers for me to like it at all.

The other invasive is dandelions. They don’t seem as bad to me but maybe that is just because they’ve been around my whole life. They too can be eaten and I have gotten leaves from my CSA and grocery store on occasion. There flowers and seed pods are interesting topics for photography. I’ve heard one soil conservation person comment that dandelions might be a good thing for slopes since they have longer tap roots and can hold soil more effectively that shallow rooted plants. So – they do have some redeeming qualities….but they are still weeds and I’ll pull them from my deck pots before I plant the flower seeds in the next week or so.

Sycamore Buds

I cut some small sycamore branches from tree at home to show the pre-K field trip groups. When it cut the branches, they only had buds – no leaves - and that’s what the children saw. I decided to put them in water when I got home to see what would happen. The buds split and tiny leaves began to emerge about a week after the field trips!

Once they started, progress was rapid. The pictures below were taken 2 days after the earlier ones. The leaves are curled at first but quickly flatten out and begin to look like sycamore leaves.

The branches have been indoors and are not ahead of the rest of the tree. We’ve some cool nights here in Maryland and the buds on the tree are just now popping open --- at least 5 days behind my branches inside.

I also put the maple branches that I cut in water and the samaras have continued to develop but the leaf buds are still very tight.

My next project is going to be encasing some of these small leaves and seeds in clear contact paper. Hopefully it will preserve them enough that we can use them with field trips later this month and into May.
