Field Trips in the Rain

/

Last week, I volunteered for two elementary school hiking field trips at Howard County Conservancy’s Mt Pleasant Farm….and it rained both days! On Monday it was kindergarteners and the ‘hike’ was shorted from 40 minutes to 20 minutes and accomplished in mostly the nature center. We started out on the terrace above the nature center looking out over the Honor Garden…talking about trees with leaves (and looked at leaves on the ground). Then we walked quickly around the front of the building to get to the nature center…and were wet enough already. Inside the nature center there were animal skulls and pelts…seeds and leaves…preserved insects…

And tree cookies.

When I talk to kindergarteners about tree cookies, I take time to explain what they are…and that they are not to eat! We count the main rings on the Royal Paulownia and then note that the other trees grow more slowly. My favorite is the dogwood because the rings are not as regular the other samples. The children are always enjoy learning about sugar maples…and maple syrup.

The rest of the time that would have normally been hiking was spent observing and hearing about Ranger, the barred owl.

On Friday, it only sprinkled a little on the first hike with second graders while we were out and about in the meadow. It was a very cloudy day.

During the second hike, it started raining. The children were dressed for the weather and more than half of them had umbrellas. We were in the meadow collecting and analyzing soil samples when it started raining. We decided we’d done enough samples and went to learn about the rocks by looking at an old stone wall. We started making our way back to the nature center by way of the goat and chicken enclosures…noting what the animals were doing (both enclosures have shelters and that’s where the animals were…out of the rain). We stopped briefly at the old stump in front of the farm house and discovered a snake skin fragment. Then we headed in to the nature center to see the living black rat snake (Onyx), a snake we see frequently at Mt Pleasant. They were ready for lunch too!

These were my last elementary field trips for the fall season. Even with the challenge of rain, they were good experiences…for me and for the students.

Sunrise and Sunset

/

One day last week I had serendipity photo ops first thing in the morning and just as the day was ending. In the morning I looked out the front of the house and saw three deer munching on the day lily leaves around our oak. By the time I got my camera, there were only two left. I trimmed the leaves more than a month ago as they began to look ragged and was surprised that they grew back. They are probably some of the most tender green leaves around right now. The day was cloudy and wet so even though the sun had been ‘up’ for about an hour, it was still relatively dark.

Near sunset I noticed the color reflected on the clouds. They were moving rapidly so the shapes were changing. Our sycamore was already in silhouette with the vibrant color in the background.

2018 11 IMG_3115.jpg

A few minutes later the clouds still looked very orange. I zoomed to some distant tulip poplars that still had a few leaves.

2018 11 IMG_3115c.jpg

Back to our sycamore in silhouette – the cloud has the shape of some creature with two big eyes and a toothless mouth…maybe a little like Jabba the Hutt.

2018 11 IMG_3115d.jpg

Then the color was down in the trees. We don’t have a clear few of the sunset since there is a forest to our west. It was a nice end-view for the day.

A few minutes observing…witch hazel

/
20181105_090900.jpg

On a very wet morning earlier this week – I arrived at Howard County Conservancy’s Mt Pleasant Farm before a field trip with 1st graders and spent a few minutes observing witch hazel. There is one that I knew was blooming close to the Gudelsky Center entrance. It’s a low growing tree; in a forest it would be in the understory. This time of year, the leaves are yellow.

The flowers have petals that look like curly streamers coming out of the center part of the flower. On this plant they were pale yellow.

I kept by cell phone pointed downward to keep any rain from getting on the lens of the camera. It was raining enough that I needed to dry off the front of the cell phone as I walked inside.

Hiking with 4th Graders at Belmont

/

Last week I spent a morning hiking with 4th graders at Howard County Conservancy’s Belmont location. The theme for the hike was how the land has changed from it was all a forest 300+ years ago…to the way it is today with emphasis on the impact of our development of farms and factories…streets and homes.

I arrived early to help with set up. I carried a bag with materials for the terrain model to the table mid-way along the hike and then carried the other bag into the forest for the students to compare aerial photos of the Belmont area.  I took some pictures since I knew once the students arrived I wouldn’t have time for more – I am totally focused on the students while we hike. Some areas in the forest have deep leaf litter and would soak up a lot of water before the water would run off…and right now there are some leaves that are still colorful too.

Coming out of the forest I took a picture of the Belmont cemetery and the row of white pines. I took my hiking groups to the side of the cemetery and talked about the ground penetrating radar that was used a few years ago finding graves under the ground within the cemetery even where there are no markers and also where we were standing outside the fence (lot’s of fun to point out on a Halloween hike) but the conversation also included the idea of shifting of sediment and deterioration of grave markers that might have been made of wood. The pine needles that have accumulated over the years under the pines make the ground feel spongy; that surprised some of the students….and that area would soak up a lot of water just as the leaf litter does – like a sponge.

There was a terrain model that we poured blue liquid over to represent the normal river level…then more blue liquid to be a minor flood (houses nearest the river wet)…up to the level representing the 1868 flood which washed away Elkridge Landing and parts of Ellicott City. The mills never recovered, and towns ceased to exist. The students were surprised to learn that the flood experienced by Ellicott City in 2018 was not that much below 1868 and it was higher than the flood caused by Hurricane Agnes (1972) in Ellicott City.

20181031_095446.jpg

Overall – it was a great day for a fall hike with 4th graders!

BioBlitz with 7th Graders

/

I spent two mornings at Howard County Conservancy’s Mt. Pleasant with 7th graders for a BioBlitz.

Both days were cool and a little breezy. I arrived early enough the first day to take a few pictures of the fall gardens (in the calm before almost chaos)

And to look at the Green Infrastructure Network map again….enough to locate the approximate location of their school and think through how to talk about hubs/corridors in the county.

2018 10 IMG_3037.jpg
2018 10 biobli2.jpg

I had 11 students and a chaperone for about 2 hours and we found quite a lot. The most exciting – for me and the students on the first day – was a spotted salamander when we rolled over a log.

The brightly colored shelf-fungus and a wolf spider were good finds too.

On both days – one of the students borrowed my macro lens and became a specialist at getting macro pictures. Overall – the students handled being a little cold very well and stayed focused the BioBlitz for most of the two hours.

Milkweed Seeds

/

I cut the milkweed stalks in my yard down before they could produce seeds; my stand is big enough and my neighbors might not appreciate milkweed coming up in their yard. I was hiking recently in the Middle Patuxent Environmental Area (hiking back from the river after a stream assessment with high schoolers) and spotted some seed pods with fluffy seeds emerging. We’d had some dry days and the white fiber parachutes were carrying seeds away with every breeze – unless they were still matted inside the split pod.

Milkweed pods are one of my favorite subjects for photography in the fall. The bright white fibers draw the eye in the browning meadows.

Hopefully all these seeds flew away before the rains later that afternoon. Rain tends to destroy the parachute so the seeds are stuck either in the pod or in a soggy mass on the ground.

Milkweed also comes up from the roots so even if these seeds don’t find a way to grow, the stand will be denser next year with plants coming up from all along the roots already there. I noticed some young plants near the stand and wondered if some of the warm days we had in October prompted the plants to send up spring-like shoots.

It was a cold morning last week when I headed out at dawn to help set up for another Middle Patuxent stream assessment – this time at the Middle Patuxent Environmental Area which is upstream from the other Middle Patuxent field trips I had done this fall. It was a field trip that had been canceled previously because of high water (see the post about hike I made that day).

The day was cloudy but dry. I enjoyed the hike down to the river.

The water was low enough that we could walk across near one of the riffles without jumping from rock to rock. I was wearing two pairs of socks to fill out my boots and keep my feet warm. My table got macroinvertebrate identification (after we captured them) was set up on a gravel island in the middle of the river. The other two were on the bank further downstream.

20181026_104804.jpg

Mayfly larvae were the more numerous critters we found – all sizes. There were numerous good photos taken with the macro lens by the students.

But the highlights of the day were two larger critters. The crayfish was large enough that it had to be in the plastic bin while the hellgrammite fit into the ice cube tray. Photos of these did not require the macro lens!

The group of 60 students managed reasonably well in the cold; it might have been a little warmer at the river level when we were dry. I realized as I walked back up the path afterwards that I was cold but for the two hours I was in the river – I was warm enough and overwhelmingly focused on the experience with the students.

Saturday Hike – Part II

/

We started down from the Howard County Conservancy’s Belmont Carriage House shortly after 10 AM with 21 hikers. I wanted to make good time for the downhill part of the hike to the Patapsco River in the Avalon area of the state park. I didn’t stop for any pictures. Until we got down to the river.

The water was cloudy with silt and the gravel bars that used to be in the center (where tiger swallowtail butterflies liked to puddle in the summer) were gone. The high volume of rainfall has swept them way. The shallows don’t look so shallow any more.

2018 10 IMG_2988.jpg

I noticed a stand of young sycamores as we started back. I wondered if they were planted or had just come up from seeds. There are not many truly large trees along the river because of the violence of the floods.

2018 10 IMG_2991.jpg

The paths were muddy and sometimes slippery with wet leaves. The rain from the night before was still running off. There were two downed trees across the trail at one point…the leaves on one still looked fresh – like it might have fallen the night before. It was easy enough to go under them rather than over.

We’d had enough dry days that there were some noticeable shelf fungi but none of the brightly colored ‘new’ ones that appear after several days of rain.

2018 10 IMG_2992.jpg

There was a light coating of leaves on the forest floor but a lot of green too.

2018 10 IMG_2993.jpg
2018 10 IMG_2995.jpg

We knew were past the half way point going back when we came to the Morning Choice Trail.

There were more signs of trees that had fallen recently. I zoomed in on part of this one when I saw a funnel spider web that looked a lot like an owl!

We came out through the stand of big leaf magnolias and into the trail beside a hay field and thne were within sight of the carriage house shortly after noon. I had my 12,000 steps for the day!

Saturday Hike – Part I

/
2018 10 IMG_2984.jpg

Last Saturday, I lead a hike from Howard County Conservancy’s Belmont Carriage House down to the Patapsco River. It was a cool gray morning – a good day for a fall hike.

The starlings and male brown-headed cowbirds were busy around the carriage house when I arrived.

2018 10 IMG_2979.jpg
2018 10 IMG_2982.jpg

I appreciated the leaf color of the sugar maple near the carriage house since most of the other leaves in our area seem to be staying green on the trees or falling off before they change color

I noticed that the pods on the butterfly weed had opened but the seeds were still tightly packed inside. Perhaps the rain has come frequently enough this year that the white fibers haven’t dried out enough to become the parachutes for the seeds.

That was the calm before the hike. The list of people that had signed up was long – over 50 people. But only 21 showed up. That was large enough and I was glad that another volunteer was available to bring up the rear on the way down and be at the front for the uphill trek.

More about the hike itself in tomorrow’s post.

Cold Hike with 1st Graders

/

Last week, I hiked with groups of 1st graders at the Howard County Conservancy’s Mt. Pleasant Farm. It was the coldest field trip of the fall season so far – with the temperature in the 40s. On the plus side – it was a sunny day so it looked warmer that it felt.  

20181018_090539.jpg

I arrived early to take some pictures before the buses and put on several layers before I left my car. The leaves are still mostly green.

It like the sunshine on the ferns and seed pods.

20181018_092049.jpg

There were still a few flowers late season flowers for the pollinators still around or coming through. Apparently, there are still a few hummingbirds although they are usually mostly further south by this time.

There were several other field trip groups at the Mt. Pleasant on the same day: high schoolers down at the stream and a group of babies/toddlers/pre-K children with parents. All three groups arrived in about 30 minutes: the high school bus then the young group in cars that seemed to fill up half the parking lot (a larger informal group that usual) and then the 2 bus loads of 1st graders, their teachers, and their chaperones.

The students were dressed for the weather and enjoyed hiking. We talked about what lives in trees and saw squirrels and their nests….some birds. We saw the domestic chickens and goats…talked about how they stayed warm and what they ate.

20181018_114513.jpg

The children found a snake skin on a stump…and the second group saw a very small rat snake sunning itself on an old stump.

Good hikes and activities…then hand washing and a picnic! What a great 1st grade morning!

Common Buckeye Butterfly

/
2018 10 IMG_2968.jpg

Last Saturday, I was at Robinson Nature Center about noon enjoying the native plant garden near the front of the nature center. When I noticed a Common Bucky Butterfly enjoying some of the fall flowers.

I took pictures from several perspectives. The colors and markings are very distinctive. It has knobs on the end of the antennae and whitish palpi between its eyes. It’s reported to like flowers with yellow centers…and that it what this individual was enjoying.

The entrance of the nature center has a nice display of fall pumpkins and squash.

I had come to the nature center earlier to participate look at macroinvertebrates in this part of the Middle Patuxent – upstream from the location for the two assessment with high schoolers earlier this week. Two differences: 1) no clams at Robinson….lots of them further down the river and 2) we found a snail…didn’t find any downstream. We found more of everything but that could have been the difference between and adult group and high schoolers….and we had more time to do the project.

In the Middle Patuxent – Day 2

/

Last Wednesday was the second day of the week that I volunteered through the Howard County Conservancy to help with a high school Stream Assessment in the Middle Patuxent River off the Kings Contrivance Loop trail; same location, different high school. The day still started out in near darkness…but then it was sunny!

We set up for the macroinvertebrate identification and quality assessment: collection bins and buckets and nets at the river level then tables with identification and analysis materials to the side of the trail.

20181017_091512.jpg

I took a river level picture…much better without the rain – although the temperature was in the 50s rather than the 60s like Monday.

20181017_101142.jpg

This time the white board worked very well to summarize the macroinvertebrates the students found and identified.

The students took pictures of the critters during the field trip. I let them borrow my clip-on macro lens. One girl had a very steady hand and took video of one showing gill movement. I took my pictures after the students headed back to school. Here are some my favorites.

20181017_091326.jpg

Two entwined netspinning caddisfly larvae and a dragonfly larvae

A lot of dragonfly larvae…different instars and species

20181017_100344.jpg

Another dragonfly larvae – one that seems to like this particular stretch of the Middle Patuxent. We’ll see if we find any upstream in day 3.

20181017_100356.jpg

Several different pictures of the same damselfly larvae. We use ice cube trays to separate the critters while we are identifying them…they are ‘macro’ but not very big!

Two different kinds of mayfly larvae.

20181017_102329.jpg

As I walked back up the hill to my car, I savored the sunny day and the near solitude of the walk.

20181017_102518.jpg

The feeder streams still had trickles of water. One neighborhood woman that came by before the students arrived told me that the river had gotten bigger in the 30 years she has lived in the area and walked the trail. The river has dug down through sediment enough that it becomes a roaring torrent when it rains hard and rarely connects to its floodplain.

20181017_102847.jpg

I couldn’t resist a fall leaf. Most of the forest is still green. We’re still waiting for fall color!

In the Middle Patuxent River – Day 1

/

Last Monday, I volunteered through the Howard County Conservancy to help with a high school Stream Assessment in the Middle Patuxent River off the Kings Contrivance Loop trail. It was raining when I left the house before sunrise and continued through the assessment.

20181015_075250.jpg

It was starting to get lighter when I arrived at the site and helped to set up for the macroinvertebrate collection and identification.

We discovered very quickly that the white boards would not work in the rain – even if we wiped them off immediately before we tried to write.

Fortunately, the rain was gentle and water still relatively clear. This part of the river is silty…not a lot of cobbles.

20181015_082352.jpg

We found quite a few critters. There were at least 3 different kinds of dragonfly larvae; I had never seen the kind with a more rounded abdomen. All the other critters were the more typical ones.

Paper was quickly damaged in the rain. The students took pictures and (hopefully) enough data sheets will survive to make a good composite data set for the class. I took a picture of one of the sheets. The macroinvertebrate analysis done on site showed the river to be in the moderate range.

20181015_095430.jpg

The students finished and headed to their buses. As I made my way up the hill to my car, I stopped to look at some of the feeder rivulets along the way (there were bridges although I could have easily walked across these with my boots). There were some signs of erosion along the banks….it wasn’t as bad as I thought it might be after our recent downpours.

There were also some colorful fungi. Orange is seen frequently.

There was an area with a lot of shelf fungi on logs. It was so damp that some seemed to have something green growing on them.

20181015_101407.jpg

My favorite was nearby – bright red and orange with yellow on the edge.

Spider Webs at Centennial Lake

/

Spider webs stand out when they have water droplets on the silk – either from dew or fog (or water sprayed by a photographer keen to photograph them). Last week at Centennial Park the water droplets were from fog. I was surprised at how many spider webs I saw along the path…. realizing that there are a lot more spiders around than we usually notice.

Some of the webs had probably caught something since they had gaping holes.

Others were more intact or maybe partially repaired.

As I was getting ready to leave the park I notice a large funnel web near the trunk of a pine. It too was more visible because of the fog. I didn’t see the spider, but it was probably there somewhere. I was so focused on the webs in the trees that I wasn’t looking for the funnels on the ground!

Mushrooms at Centennial Park

/

On the foggy morning I spent at Centennial Park last week, I found some tiny mushrooms in the raised bed across the pathway from the boat rentals. They were growing in the mulch and were ‘fruiting’ because of the very wet conditions we’ve had recently. Some were very hard to spot because their color’s were not that different form the mulch – and they were small. I stood far enough back so that I could use the zoom to photograph them without climbing into the mulch.

There were some birds nest fungi that were mostly empty nests although a  few of the ‘eggs’ were still nearby.

My favorites were brightly colored like these very small red mushrooms (note there is a centipede just to the left of the mushrooms).

My favorites were some tiny orange mushrooms with yellow stalks and edges. They seemed to be glowing – standing out in their drab surroundings.

I walked over to some pine trees near the parking lot while I waited for my husband to finish his brisk walk around the lake. There were some larger mushrooms coming up through the pine needles.
