Winters Coming!?

Field Observations

This week for the response question I was asked to think about the strategies for winter survival for my species in Wysong loop.  So as I was walking out there early on the first morning of August I was trying to imagine winter in the Wysong.  As I was just sitting still trying to take notes of some new plants and sweating surrounded by horse flies and mosquitos I couldn’t help but dream of winter.  Also this week our friendly farmer neighbor decided to start emptying his cattle lagoon onto the field which in the early morning fog sends over wonderful aromas which helps get me moving! 

The beautiful old field early Monday morning, just as the sun was hitting the field.
So once I got over dreaming about winter and snow, even though I’m sure when it’s here I will be wishing for summer, I actually began making observations.  It is amazing in how just one short week things can really change.  This week as you can see in the photos I had just splashes of new colors everywhere, from small white flowers to the tall ironweed which continues to grow and expand its brilliant purple flowers.  Also new this week was some of the goldenrod beginning to open up and emerge, so I am hoping that over the next few weeks, before this blog is over, that I can show you the field covered in yellow!  I have found that when I come out to do observations every day I can’t see any differences thus I have been “avoiding” the area and visiting at no more than every three days so I can better observe the changes.

Some new goldenrod growth, fall is coming!
I also checked on my large milkweed bug nymphs and they seem to be growing more and more each time I see them and looking more like their adult forms.  Each time I visit there is new animal life, some of which is exciting to see, like birds flying over.  On Monday morning for example I had a great blue heron fly over my old field, probably leaving from one wetland to travel elsewhere, but I was so captivated by the beautiful creature that I forgot to take a photo.  It always amazes me that such a large bird can be such a graceful and quiet flyer!  Also I have been trying my best to start documenting more birds in my old field after our bird banding experience, but unlike trees who always stand nice, tall, and unmoving the birds are constantly on the move in the mornings darting from one area to the other.  Perhaps over the next couple of weeks I can just practice some more!

Species Identification

Big Bluestem (Andropogon gerardii)
Big Bluestem is a native perennial warm season grass that is prevalent around Merry Lea property and throughout most of the United States.  It is a tufted grass that forms sod and has short and scaly rhizomes, it can be distinguished from other warm season grasses by the blueish coloration at the base.  The heights are quite noticeable across Wysong as it can reach upwards of 6-8 feet tall in areas, as this area is mostly protected from grazing (Big Bluestem, 2004).  Another noticeable characteristic is the 3 part flower or spikelets that appear like a characteristic “turkey foot” which can be seen in the photos below.

Big Bluestem is a very important grass species in prairie ecosystems and it can also be used for mine reclamation, logging road restoration and other projects that have sandier or dry soil conditions.   Also it is used as an erosion control due to the extensive rooting depths common with prairie plants and is used for rain water erosion as well as wind erosion due to the tall heights.  It is best adapted to moist, sandy, or loam based soils but can also occur in drier soils.  It is well adapted to prairie conditions, which is partly why it is found so prevalent in this area (Big Bluestem, 2004).  Also less than a ¼ mile away is a larger prairie which could be where the seed source came from originally and since then has just spread naturally across the field starting on the northern side moving out from there.

Historically Indians and early settlers used the roots as diuretics and to help alleviate stomach pains, as well as the leaf extracts were used for fever washes and analgesic.  The leaves were used to help fasten support poles of structures and to cover fruit during ripening and drying to protect from pests.  Now Big Bluestem is a well sought after plant for restorations projects, as well as in landscaping, and foraging, as it provides a high quality crude protein for cattle (Big Bluestem, 2004).

Wild Bergamot (Monarda fistulosa)
Wild Bergamot is also knows as bee balm, is an aromatic herbaceous perennial.  It forms a dense cluster of lavender to purplish/lilac pink tubular flowers sitting on a square stem.  The leaves are about 2.5 inches long and are grayish triangular shaped, and are joined opposite on the stem.  They can reach heights up to four feet and flower from June to September (Newcomb, 1977 & Thieret et al. 2001).  
Wild Bergamot (Monarda fistulosa) typically found around the edge of the old field.  (K. Bradley July 31, 2016)
Here in the old field there was an early flush of flowers and now is a second flush just starting to flower, providing a great splash of color and aroma.  Wild Bergamot prefers dry fields, thickets, prairies, and borders and is found throughout the United States.  Here it is common across Wysong along the edges with not much occurring in the center of the field.  This could be due to less competition along the edges of the fields compared to the middle.

Historically bee balm was used in a wide variety of purposes such as boiling the leaves down for mint tea, as well as used the oil to treat respiratory ailments (Wild Bergamot, 2000).  Now it is commonly used to attract pollinators such as bees, butterflies, and humming birds due to the bright and showy flowers, and nutritious nectar.  Here in the Wysong old field and across Merry Lea bees are constantly found around this plant.  The showy aromatic flowers are also great for floral arrangements!

Japanese Beetle (Popilla japonica)
The Japanese beetle is native to northern Japan and was first found in the United States in New Jersey in 1916 believed to have come over on iris roots, and since then they have spread across the country.  What is unique about this beetle is that the adults can eat over 300 different species of plants!  The main feeding usually occurs between June through August, and the beetle eats between the leaf veins giving the leaves a skeletonized look.  Since the accidental introduction measures have been taken to reduce populations by using parasitic flies and wasps that prey on the beetle larvae (Japanese Beetle, 2016).

The beetle itself is 3/8 to ½ inch oval and a sturdy body.  The body is bright metallic green and the elytra are mostly brownish as you can see in the photos below.  They have grayish black hair on the underside and characteristic 5 patches of white hair along each side of abdomen with two white tufts at the tips.  The adults deposit 1-4 yellowish white eggs onto the soil at a time and the larvae overwinter in the soil and then pupate in the spring.  So each year one generation of adults emerge in the summer as the blackberries ripen and in the north it can take two years for this cycle to occur (Milne and Milne, 1980). 
Japanese Beetle (Popilla japonica) (K. Bradley July 31, 2016)
Due to the large variety of plants they can eat they are able to easily establish themselves and can disperse by flying, and commonly form large groups around specific plants (Milne and Milne, 1980).  It is also important to note that healthy plants generally can recover after a Japanese beetle feeding but plants that are stressed due to other reasons (drought, etc.) may not be able to recover.  So here in the old field I am not surprised to see them as I have recently been seeing them around other areas, particularly around the farmstead in the gardens.  They have more than sufficient food sources in Wysong and have many friends around to keep them company.

Downy Woodpecker (Picoides pubescens)
The downy woodpecker is a common and familiar sight through most of North America.  They are commonly found on backyard feeders, in parks, and patches of trees, and are one of the smallest woodpeckers with a very short bill.  They are only about 6 inches tall as an adult and are very acrobatic in their foraging behaviors when compared to other woodpeckers.  The adult males have a red crown, small bills, white patch on their back, and dark bars on their lower feathers.  The female does not have the red crown but rather conspicuous tufts of nasal bristles (hairs out towards the beak), a clean white chest, and extensive white spots on the wings, both of these you can see clearly in the photos below (Downy Woodpecker, 2015 & Sibley, 2003).

The call is a short and gentle flat pik, and they drum short and slowly and repeat frequently, usually ten or more times per minute.  Here in Wysong just about every time that I am out to visit they are usually found on the staghorn sumac moving up and down the dead limbs and trunk or on a nearby tree.  Woodpeckers like a Downy normally eat insects and bugs and the larvae which is why old trees and branches provide the perfect microhabitat to find food.  So here both in and surrounding Wysong there is plenty of food source as well as forest cover.

Response Question
This week as mentioned before the focus is on strategies for winter survival for the plants in my ecosystem.  The two main problems for any plants going into winter is trying to reduce water loss (as well as have water available) and the cold temperatures.  So I am going to first talk about adaptations of trees as they prepare and survive the cold winter.  Many trees like Eastern Cottonwood is a deciduous which means that each fall it loses its leaves, other trees like the Eastern Red Cedar, also found in my ecosystem, have a bit of an advantage as they keep their needles during the winter so on sunny winter days they are still able to photosynthesize. 

The best adaptations trees have to preparing for the cold is the gradual temperature changes, so for example not going from 80 degrees one day to 5 degrees the next.  Trees are able to make both chemical and structural adaptations.  When the trees have this gradual temperature decline they can build up their cold tolerance.  The cells in the trees can increase their lipid concentrations with less complex lipids, help break apart long protein chains, and then the water can migrate out of the cell.  So the water outside the trees cell wall will freeze first, and as normal as water changes from a liquid to a solid a very small amount of heat is released which helps prevent the cellular water from freezing (Cook, 2013).  Then as the spring comes this all happens in reverse and hopefully without any late unexpected frosts or large ice storms the trees will live to see another spring!

For many of the old field plants the most important adaptation for survival is a large extensive root system.  Just like with the trees ideally the winter will slowly come on giving the plants time to adapt. In the late summer/ early fall for example the soils in general become drier and the vegetation takes up nitrogen from the soil providing essential food for the long winter.  For many healthy plants they are able to store the energy that the leaves manufacture over the summer, and with a healthy root system acting as a storage tank holding the precious sugars and nutrients.  These sugars and nutrients will be very important to the plants again in the spring to get them started photosynthesizing again (All About Snow, 2016).   


Some plants just go completely dormant and the biomass on top of the ground dies off, leaving only root structures alive which are advantageous to surviving the winter. Other plants produce large amount of seeds which are able to overwinter in the snow pack and will begin growing when ground temperatures become warm enough.  Depending on the year with snow pack once snow has settled it can provide a “mini shelter” and protect the plant from the freezing temperatures and wind.  Here in Noble county according to the state of Indiana the frost line is at 50-60’’ (Depth of Frost Line, 2016).  Also many plants are adapted with thick and waxy coatings that can help protect them against the cold winds.  So overall there are many adaptations that plants and trees have made to overwinter, it’s not as simple as putting on a good warm pair of boots and snow suit!

Creative Contribution
This week I decided to complete more of an art project that could be used to demonstrate insects at the fair, as well as insects commonly found in my ecosystem. Although the totem pole may have been forgotten at the fair it can still be used for future educational purposes.  So below you will see two of my creations using recycled materials (old ½ gallon milk jug and cool whip container).  The reason for making these was to help demonstrate the various characteristics that insects share such as 2 pairs of wings and 2 antennae.  The first is a honey bee taking a photo next to one of its favorite nectar sources, Wild Bergamot.  The second is a ladybug beetle next to Queen Anne’s lace (which if you look closely also has a ladybug beetle sitting on it).  So it was just a more fun change of pace and an opportunity to help educate others about insects and interact with my ecosystem through the eyes of a child, creating a story in my head!
