Our New Neighborhood – January 2023

/

It was warmer than I expected when I walked around our neighborhood pond…a pleasant surprise. I photographed the Lambs ear in our flower bed on the way out…both the mother plant and ‘children’ seem to be weathering the winter.

The dying back of vegetation makes it easier to see nests in the trees and the reeds/grasses at the side of the pond. Was this one built by a red-winged blackbird last spring?

There are many leaves decaying in the pond…and bright green algae. I wondered if there might be some interesting macroinvertebrates in the water. We did see a lot of dragonflies in the summer so their larvae might be in the water. Maybe I will get a small net to see what is hiding in the decaying leaves.

I always stop to look at the weeping willow at the edge of the pond that has grown around a metal stake. The leaves are gone now…but the lichen on the trunk is colorful! I took pictures at various magnifications with my phone (Samsung Galaxy S10e). I’ll continue to check the lichen on my walks around the neighborhood pond…see how much it changes when the weather is warmer.

In the Middle Patuxent River – 1

/
20211005_084940.jpg

Another morning in a local river last week – the Middle Patuxent near King’s Contrivance. There are pathways from the neighborhood streets nearby to connect to the Kings Contrivance Loop that are lined with the big trees of the easement along the river.

A part of the Loop trail parallels the river for a short distance and there is a root supported path down to the river in one spot. The river was more silt than cobbles…more big trees had fallen in from the bank since the last time I was there (pre-pandemic). Still – being in the river is a wonderful outdoor experience every time. There are gentle sounds of the water moving…trees ruffled by little breezes. It was a cloudy day but enough light filtered through the canopy to make patterns on the surface of the water.

I took some pictures of leaves that had fallen recently and were plastered to the sandy beach near the water. Soon there will be a lot more.

And then the students arrived and it was a flurry of activity while we collected and identified macroinvertebrates…decided that, based on our sample, the water quality was poor but not dead. There were macroinvertebrates in good numbers…but skewed toward species that are tolerant to pollution. Some of the students were surprised at how easy it was to step in water just over the height of their boots! They good naturedly made their way to shore, took boots off one at a time to pour out the water.

And then the time was up - the students headed back to their buses and the river was quiet again. I climbed back up the bank on root ‘steps’….glad that the abundant green on both sides of steep bank was NOT poison ivy!

Near the Little Patuxent River

/

On a recent morning – I headed out to the stream that flows under Broken Land Parkway from Lake Elkhorn just before it joins the Little Patuxent River for a volunteer gig – guiding a stream survey done by high school students. Near the bridge that crosses the stream on the Patuxent Branch Trail, there was muddy trail (poison ivy on each side…glad I had on long pants and high boots) to allow access down to stream. We set up our gear around three tables. There was not much dry area to set them up but the water was shallow. A partner and I guided 10 students to collect and ID macroinvertebrates from one of the tables while other volunteers did the same at two others. We had about 45 minutes….and then we got another group of 10 to do it again.

I took some pictures before and after the students arrived. The steam has a lot of vegetation on the banks but the stream has been eroded  - with some trees toppling over from being undercut by rapidly moving water. It is in an area where there is a lot of impervious surface. When it rains – the water rushes down to the stream where it carries away anything in the eroded channel; there is no connection to a flood plain that to slow down the water. It doesn’t take long for it to run off further downstream because we are in the Pediment rather than the Coastal Plain (i.e. there is always an incline for the water to follow).

The water quality was ‘very poor’ based on the types of macroinvertebrates that we found…however – we found quite a few of the types we found. The stream is not dead. Life holds on tight in this suburban stream.

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.

Nine things you should know about sea horses – The males give birth! Like many creatures right now – they are in trouble from climate change (and overfishing in some parts of the world). Not long ago – I learned that there is a species of seahorse native to the Chesapeake Bay. They live in sea grasses and estuaries…habitats that are in trouble.

Electric cars and batteries: how will the world produce enough? – One of the important steps that needs to ramp up as batteries (and solar cells) reach end of life – is recycling. We need to think about closed loops for the resources required to manufacture future renewables!

New analysis of landmark scurvy study leads to update on vitamin C needs – An example of the research behind how those ‘daily requirements’ of vitamins and minerals were developed. I wonder if more of the values need to go through a validation…how many would change just as the vitamin C requirement did.

Top 10 Grassland Species Across the Globe – The ones we have in the US are Long-billed Curlew, Black-footed Ferret, Pronghorn, Swift Fox, and American Bison.

The multi-billion dollar giants that are melting away – Glaciers. When they are gone…many parts of the world will be drier places. This article is primarily about central Asia…but the situation in South America is similar.

Loss of biodiversity in streams threatens vital biological process – Fungi and bacteria can’t do the decomposition job alone…the aquatic insects (often larvae) and crustaceans are needed too. And the populations and diversity of those organisms in our streams is declining.

Top 25 birds of the week: plumage! – Bird photographs…always colorful and interesting.

Gender revolutions in who holds the purse strings – The study was done in Britain…I wonder if similar (or different) changes are happening elsewhere in the world.

‘Polluter pays’ policy could speed up emission reductions and removal of atmospheric CO2 – A change that could speed up the transition we need to make…if we can somehow overcome the lobbying for the status quo trajectory.

Photography In The National Parks: Fun Fact Photography – This is a kind of photography you can do in lots of places. A little curiosity and a camera…some web searches…a neat cycle of learning/art that can turn again and again.

Chasing Little Frost Trees in a Prairie Wetland | The Prairie Ecologist – We haven’t have many days for me to look for frost trees here in Maryland this year. This is always a matter of taking advantage of a frosty sunny day when it’s fun to look for interesting frost formations on exposed surfaces – grass – windshields, etc.

Stoneflies and mayflies, canaries of our streams – It’s great to see an article about the adult forms of the insects we collect as macroinvertebrates (larval form) when we do water quality monitoring either quarterly or with high school students on a field trip to a river.

Earthquakes in and around Yellowstone: How Often Do They Occur? – There are lots of them! About 5 that are strong enough to be felt have happened each year over the past decade.

Top strategies for successful weight loss maintenance-- ScienceDaily - Choosing healthy food, tracking what you eat and using positive self-talk….seems like common sense, but it is not ‘easy’ and so we struggle on. It comes down to making changes for the long term rather than just for a little while. New habits are always tough but, once truly habitual, become just the way be live our lives.  

Eero Järnefelt, painter of Finnish nature | Europeana Blog – Images of the natural world in the late 1800s. Koli National Park in eastern Finland was visited by the painter frequently.

Sustainable Farming Comes to America's Heartland | CleanTechnica – Iowa farmers…leading with their actions…responding to climate and environmental changes to farm better.

Can we heat buildings without burning fossil fuels? - BBC Future – Capturing heat from nearby places…using it for heating. It’s geothermal in the cities!

Bloom in McMurdo Sound – Green swirls in the water off Antarctica (some of the green color might be on the ice as well.

Camera Trap Chronicles: Cool Critters of New Hampshire – Maybe sometime  we’ll put our camera, currently pointed at the birdfeeder, in another location….see what comes into our backyard. I know we have deer but there could be other things as well. Our camera already picked up what looked like a racoon on our deck.

Top 25 birds of the week: groups of birds – Beautiful birds…a good ‘last addition’ to the gleanings list this week.

Ten Little Celebrations – January 2020

/

2020 has started out with more activity than I anticipated….more volunteering, more classes, more events…and some travel at the end of the month.

2020 01 IMG_7039.jpg

Bluebird passing through: We don’t see bluebirds around that much….so it’s a special day when we do see one.

47th wedding anniversary: It doesn’t seem like such a long time…compared to my parents celebrating 67 years. I’m going to think of something special for our 50th coming up in 3 years!

20191229_142625.jpg

Children enjoying the Touch Tank: There are moments in every hour that I spend volunteering at Robinson Nature Center’s saltwater touch tank that are little celebrations for me and for the children. Whether it is awe from something an animal does…or how they feel…or just understanding something new.

Conowingo Eagles: Even on a morning I don’t get any particularly good pictures – I enjoy every trip we make to the Conowingo…and that the eagle population is back from the brink!

Hot tea with cream: Or maybe with just milk. It’s my favorite winter beverage.

20200115_095546.jpg

Middle Patuxent Water Monitoring: I always enjoy getting in the river and then doing the gleaning of the macroinvertebrates to identify. Since it was winter, I was braced to get very cold…but we had a wonderful sunny (not too cold) day!

Honing skills for volunteer gig: None of the classes were very long but were informative and applicable to me becoming a better volunteer. The topics ranged from autism, Howard Country Green Infrastructure Network, sensitivity training (impact of microaggression), outdoor wear fashion and function, and the spotted lantern fly. Wow – quiet a range of topics and all the presentations were excellent.

2020 01 IMG_7080.jpg

Snow in the afternoon: So beautiful. I celebrate every snow these days because I don’t have to drive in it!

Zentangle® with Howard County Conservancy volunteers: I love guiding group Zentangle sessions. This particular group seemed to enjoy the session…and had some ideas about ‘next steps’ in a practice. And like the campers last summer…got a little Zen as well.

20200116_120801(0).jpg

Cooper’s Hawk on a Snowy morning: Often a ‘little celebration’ is a surprise that just happens. Seeing the Cooper’s Hawk fly into our sycamore was that kind of celebration – although I am glad the hawk is not around my backyard more frequently (since I enjoy the other birds).

In the Middle Patuxent River – January 2020

/

Last week I was in the Middle Patuxent River at Robinson Nature Center for the quarterly (winter) water monitoring. The temperature was in the 50s and sunny – an easier sampling than most years. I always like to take some pictures from right at or in the river. It’s a different perspective that being on a forest or meadow trail.

20200115_095557.jpg

I was the only one of the sampling crew with just boots….everyone else had waders. But the river level was not too high. I didn’t get water in my boots…and no one fell in either.

20200117_151004.jpg
20200115_095734.jpg

We caught a madtom (catfish) in one of the collection nets (collecting macroinvertebrates). We took pictures and let it go before we headed up the hill to the Nature Center.

In the lab, we divided the buckets of samples into plastic bins and we all started collecting macros from our bins and randomly putting them into the two partitioned trays.

20200115_120727.jpg

Then random numbers were drawn to determine the compartments we would id and count until we got to 100….and then we looked at what was left for anything unique. Almost everyone took a few pictures of macros. The most unique thing we found was a white worm!

This was the first time I participated in a winter monitoring and it might have spoiled me – being as warm as it was.

In the Middle Patuxent – Again

/

Last week, I was in the Middle Patuxent River again for a couple of mornings – a little downstream from the MPEA location that I posted about yesterday. The biggest difference was more water! It was wide enough to make using a seine possible although the D-nets worked well for collecting macro invertebrates as well. I celebrated that my last group found a hellgrammite!

Another plus for the site – no scrambling over rocks to set up field tables and supplies for identifying the critters we caught. The access was down a steep bank with roots making reasonable stairs; no one had a problem getting down even in clunky river boots. And once the students were in the river…magic happened. Everyone participated!

2019 10 IMG_5785.jpg

The site was close enough to one of the schools that the students walked down. The path was a paved tail through forest along the river…with housing developments sometimes visible on both sides.

The little streams that feed into the river are showing the erosion caused by the impervious surface that reduces the area’s ability to soak up water before it gets to the river.

But the trees are tall, and the days were sunny and just cool enough to realize it was fall. Excellent weather to be in the river.

Smartphone Nature Photography – part 1

/
20180721_083226.jpg

We almost always have our smartphones with us….ready for those natural events that just happen and for planned photoshoots. I pulled together a presentation of a Maryland Master Naturalist retreat on the topic and am using it as a basis for the blog posts for today and tomorrow.

Gear

Learn about the camera in your phone. Two critical aspects: 1) Usually the autofocus is reasonably good but tapping on the screen where you want the focus to be can sometimes improve results. Do some experiments to see how close you can be and maintain the focus on your subject. 2) Realize that the zoom is digital – not optical. You are better off getting close to your subject rather than zooming. This is difficult if your subject is an animal that will move if you get close. Birds are notoriously difficult to photograph with a phone.

Consider a lanyard. I like to carry my phone on a lanyard (one that is structured to not obstruct the camera) so that I can be ‘hands free’ while I am hiking or rolling over logs…just doing regular naturalist things.  I want my phone to be easy to access – easier than getting it out of a pocket or pack.

20190115_084222.jpg

I enjoy using macro lenses. I have 3 different kinds (8x, 15x, and 60x) and tend to use the 15x clip the most. Sometimes I just have it on my phone so that I can move it over the camera as needed. The depth of field is very shallow with the magnification and the phone must be close to the subject. Practice the best stance to steady your hands. I find that tucking my elbows into my body helps….and using one had to hold the phone and the other to take the picture.

Examples of Smartphone nature photography

BioBlitz. Almost all the BioBlitz pictures are taken with smartphones or tablets. Sometimes we use hands for scale – and sometimes the macro lens gives a new perspective! These are pictures taken during BiobBlitz: spotted salamander, wooly bear caterpillar, milkweed.

Landscapes.  The joy of being outdoors! Try to get something of high interest in the landscape: the trail as a leading line, clouds over the trees, an early winter scene with bare trees/large rock/pines.

20171201_095022.jpg

Macro. The macro lens offers to many opportunities to observe more closely than you can observe with just your eye: clams filter feeding, the center of sunflower.

A chicory flower, a newly hatched Monarch butterfly caterpillar turning to eat its egg covering, and damselfly larvae.

A few minutes observing. I play a game with myself looking closely at one thing and taking photos as fast as I can over a short period of time. In this case it was a sweet bay magnolia. There were seed pods at several stages of development and some eggs under a leaf (maybe a leaf footed bug…if I was patient enough I could see what hatched but that was outside my time box).

(To be continued tomorrow…)

Drug pollution concentrates in stream bugs, passes to predators in water and on land: Animals that eat insects in or near streams at risk of being dosed with pharmaceuticals -- ScienceDaily – Wow – the existence of macroinvertebrates in our local rivers is an indicator of water quality (the focus of the field trips with high schooler’s I’ve been doing in recent years) but those same macroinvertebrates are probably getting a healthy dose of pharmaceuticals from the water…the fish that eat them act as concentrators….and some of those fish are eaten by people.  I hope reserarchers in the US are doing similar studies to the one described in this article. It would also be good if pharmaceutical companies would develop drugs that were not excreted in a still active form.

In the Middle Patuxent at MPEA

/
20181026_071438.jpg

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.

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.

Hollow trees host massive moth slumber parties -- ScienceDaily –black idia moths in Florida are found in roosting in hollow trees during the day (they are active at night like most moths). The post didn’t identify the species but there are black idia moths in Maryland. I am going to start looking more carefully in hollow trees when I’m hiking although it’s already close to the end of the season.

Last Spring Field Trips at Mt. Pleasant

/
2018 05 IMG_0944.jpg

The last of the Howard County Conservancy school field trips at Mt. Pleasant. The last three were between the heavy rains in our area the past couple of weeks. The first one was for 7th graders; my station was down at the Davis Branch helping them capture and identify macroinvertebrates to assess the water quality in the stream.

They put on boots and waded into the stream (and we didn’t have anyone step into a deep pool…fill their boots with water).

2018 05 IMG_0943.jpg

The water was surprising clear before they arrived. The upstream portion that was restored has slowed the flow enough to help the sediment carried by the recent rains.

The forest near the stream and the meadow was thick with late spring vegetation (some invasive plants too – like the multiflora rose).

20180601_090333.jpg

I stopped at the old foundation (now a retaining wall) on the next field trips…fascinated by the moss that was propagating, the different kinds of lichen, and what looked like a mold growing on the damp rock.

On the last field trip I checked the milkweed near the nature center for caterpillars; no luck. There was a fly that sat long enough for a picture and the buds of flowers that will open in the next few weeks.

20180604_092228.jpg

The butterfly weed was about ready to bloom as well.

The ferns were unfurling…and providing some different color to the shady scene on the way to the nature center.

20180604_092312.jpg

It was calm before the 3 buses arrived with about 120 kindergarteners! A good time was had by all…a good finale to the spring field trips at Mt. Pleasant.

Ten Little Celebrations – April 2018

/

April has gone by very quickly…full of company and travel and the beginning of the spring volunteering blitz.

Six of the 10 little celebrations were experiences outdoors – typical celebrations of springtime everywhere:

  • Blue birds and tree swallows were making their nests I the boxes at Mt. Pleasant in Maryland.
  • There were ducklings at Josey Ranch Lake in Carrollton, Texas.
  • An eared grebe at Hagerman National Wildlife Refuge near Sherman, Texas.
  • Macroinvertebrates in the Middle Patuxent close to home.
  • Spicebush in the forest behind my house and at Belmont Manor and Historic Park (both in Maryland).
  • Deciduous Magnolias blooming at Brookside Gardens. Maryland got a freeze at the wrong time in 2017 and most of the blooms turned brown from the cold just as they were opening. It was a treat to see them again this year.

I celebrated the end of two long driving days between Maryland and Texas. Both were blustery and more traffic than expected. It felt good to be done!

My new iPad is something I celebrate every time I create another Zentangle with it! I a pleasantly surprised with how easy I made the transition from pen and paper tiles to digital.

I thoroughly enjoyed a meal at a Brazilian steakhouse – this time managing to savor the flavors and not overeating. I even topped off the meal with dessert!

Finally – the Watershed Summit where the high schools of the county presented their report cards to the county government for their steams and school yards – based on data they collected last fall. Each of the 13 high schools had 2 presenters. They all were so poised and organized. It was a double celebration: the environmental findings trending positive in most cases and the quality of the students in attendance. Both bode well for the future.

Last weekend I participated in the quarterly water quality monitoring of the Middle Patuxent River at Robinson Nature Center. The temperature was in the mid-40s it felt warmer with the sun shining and the river level less breezy that the top of the nearby hills. We hiked down taking a short cut through the forest and crossed the river.

The crossing was a little tricky for those of is with boots (Me and several others) rather than waders but we made it across with only one person getting water in one of her boots. There is a whale-shaped rock that is a landmark for where the quarterly surveys take place.

We used D-nets and tubs to collect macroinvertebrates from leaf wads and riffles. The leaf wad my partner and I worked on had lots of little critters, a very large crane fly larvae and a frog. Everything went into the tub except the frog which we put back into the river (not a macroinvertebrate….and not easily contained anyway). After collecting for over an hour we headed back across the river to the lab with buckets to search through of macroinvertebrates to identify.

Back in the lab we emptied the buckets into smaller plastic bins and started separating the macroinvertebrates into ice cube trays for identification. We were after diversity and numbers of macroinvertebrates, so we were sifting through everything very carefully. I used a macro lens attached to my cell phone camera to get a few pictures.

There were a few things that were not macroinvertebrates but they were in the sample which were generally bigger than the macroinvertebrates and moved around a lot – a little distracting while we were searching. Several of us had salamanders (me included) and one person has some small fish!

Our team lead completed the form to submit for the monitoring session; the river scored about the same as the last sampling in January which is better than 85% of other Maryland water sources. Hurray for the river!

Stream Assessment – October 2017

I had planned to volunteer at two stream assessments by 9th graders in October.  Both assessments were scheduled to be at the Middle Patuxent Environmental Area but one was cancelled after a heavy rain caused a dangerous situation at the stream – so I only have pictures from one stream assessment. The stream was smaller than the two other locations along the Middle Patuxent that were assessed in September. We crossed it on some rocks (the path came to the river  near where the big log is lying on top of the rocks).

All the gear for the abiotic and biotic assessments was set up on the side of the stream across from the path. It was very calm and shady as we set up.

Then the students arrived…60 in the first group…a little break…and then another 60. I took a few pictures of critters during the break.

One last picture before the second group…what a great place to escape into nature. I’m not sure that the students experience the psychological rejuvenation I often feel in places like this when they come with the larger group (and they are teenagers) - although it was obvious that most of them enjoyed being outdoors and in the stream. When we finished the assessment, the students helped carry all the gear – including the boots – on the 15 minute hike back to the road where they got on their buses and we packed up everything into cars….another stream assessment day complete.

Macro Lens on a Smartphone

I bought a clip-on macro lens for my smart phone – something to use when I want to photograph macroinvertebrates in the field (or river). The lens (a 15x macro and 0.63 wide angle combo) is attached to a clip that is easy to position on my phone…and then take off again when I don’t want it.

I experimented a little this weekend – with an earring and a peacock feather. I discovered that it is easier to get the focus right without the case on the phone.

I am looking forward to trying it during the break between sessions in the river with students…hope they find a lot of macroinvertebrates that I can photograph!
