Underfoot: SHINGLE OAK

By, Susan Sprout

Question: When does an oak leaf not look like an oak leaf?

Answer: When it is a Shingle Oak Leaf!

We’ve been taught there are two groups of oaks: white oaks whose leaves have rounded lobes on them and red oaks with sharp pointed and toothed leaves. Shingle Oak, or Quercus imbricaria, is a type of native red oak that has no points or teeth on its leaves – just nice smooth edges. Occasionally they may be found growing on moist hillsides or in bottom lands. I spied one walking on Canfield Island last week. I did not know what it was. The tree caught my eye because of its shiny, dark green leaves that looked sort of like rhododendron leaves only smaller and not leathery. I found a small bunch of leaves that had fallen, or been chewed off the tree, lying beneath it. They were smooth-edged, ranging in size from four to six inches long and were lightly furred underneath by very short, tannish hairs. I had to use my magnifier to determine that. Of course, it was all of the acorns growing on and lying beneath it that really clued me in…IT’S A SPECIES OF OAK! 

This Shingle Oak could grow to 100 feet in height.

Shingle Oaks are more frequently found west of here in the Ohio and Mississippi River Valley regions. They are commonly used as ornamentals, and this one may well have been planted here. What a treat to find and identify it!

Shingle Oaks flower in May when their leaves are about half-grown. Their acorns will then be ripe about eighteen months later. The species name imbricaria is Latin for “like a shingle” which could indicate its use as a source of hand-split shingles or shakes. Or, maybe, because of the caps on the small brown acorns that have wedge-shaped, pointed scales overlapping to resemble a shingled roof.

Acorns are about 1/2 inch in length 

How many native animals and insects need native oak trees for food or habitat? Of 435 species of oaks worldwide, 91 are found in the United States AND support more caterpillar species than any other genus of plants in all of North America – not to mention all the animals that eat acorns. Read more about them in Doug Tallamy’s book, “The Nature of Oaks: The Rich Ecology of Our Most Essential Native Trees.”

Underfoot – A GATHERING OF TRUE BUGS (Eastern Boxelder Bugs)

By, Susan Sprout

I was surprised recently by a large amount of insects sitting on the leaves of some Great Lobelia plants.  Maybe “amazed” would be a better word for it. There were a lot of them. I needed to identify them and learn why they were gathering there. Here’s what I learned – they are our native Eastern Boxelder Bugs. Considered “true” bugs because adults have piercing, sucking mouth parts and a characteristic triangle shape between the tops of their leather-like wings. The younger bugs with them are nymphs with bright red bodies, black antennae and legs. You can find them easily in the photo because they are the ones with small slate gray or black patches on their backs. These are their wing buds. When the nymphs emerged from eggs, they were only 1.3 mm in length. (There are 25.4 mm in an inch.) So tiny! Because they are invertebrates, or animals without backbones, they are held together, supported, protected by an exoskeleton made of chitin. It is stiff and hard. When the nymphs begin to grow, they must shed and replace that rigid exoskeleton with a new larger one in order to get bigger and attain adulthood with sexual organs and wings. They need to molt five different times, becoming darker red as they mature. The red V on the back of an adult is created by its folded wing edges. The other, larger red marks on their bodies may serve as a warning to predators that they are distasteful because they contain a pungent, bad-tasting compound. Preying mantis and spiders eat them anyway. Few birds will eat them. They sun together in large groups on warm surfaces. All of that red in one place probably serves to keep hungry predators from munching on them. 

Masses of Boxelder Bugs

Boxelder Bugs feed almost entirely on the developing seeds of boxelder, maple, and ash trees. They will suck juices from the leaves, but prefer the seeds. They do not sting or transmit diseases and are not classified as a pest. They can be found east of the Rockies in woods and gardens. There is a similar species that lives west of the Rockies. In autumn, swarms of females can be seen looking for thick piles of plant debris in which to overwinter. They emerge in spring to lay eggs which are hidden in bark crevices, under leaves in safe areas. 

Look for the nymphs with small wing buds mixed in with adults

Sometimes Boxelder Bugs are confused with the Eastern Milkweed Bugs that are reddish-orange and black in color. They are true bugs, too. Get yourself a bug book and check them out!

Tracking the Wild Mammals of Pennsylvania

A white tail deer track (outlined in yellow) nestled amongst the leaves of native trees and stellaria media. The common name for this wild edible is chickweed. Chickweed is a great source of food for white tails throughout the winter as it can grow all winter long and survive underneath the snow.

Ever wonder who lives among us in the Pennsylvania Woods? We found this nifty project called “The Mammal Atlas” that will take place over a 10 year period, and is a  project that seeks to answer that very question.It is a living document that tracks  and records the wild mammals of our region as well as throughout the entire state.

The project is done in partnership with the PA Game Commission, Department of Conservation and Natural Resources (DCNR), the US Fish and Wildlife Service and many others. Additionally, some of the work and data collection is done by volunteers. 

On the home page there is a map that allows you to click on your county of interest and see what has been found to date.
There is even a check list which tells you if the animal is native, endangered and its ranking within the state. http://pamammalatlas.com/

They have this to say about using volunteers for their data collection,
“our best resource for collecting widespread data is you, the citizen scientists, submitting photographs and locations of the mammals you observe.”

Here is a cool info-graphic to get you started with identifying the mammals and birds of our region. Whether you volunteer with the Mammal Atlas or not, identifying wild animal tacks can be a great way to familiarize yourself with your local wildlife  and find out who is keeping you company on the trails or in your fields.

**As the snow begins to fall this is the perfect time to track and find who is out and about in the forests and fields of our regions. But be careful out there, if there are tracks near by, there could also be a critter nearby too. Always use caution when encountering wild animals and never provoke them or approach them.

Every Project Begins With a Story: The Kelley/New Garden Acquisition

 

Every project at NPC begins with a story. The story of family and community, and their connection to the land and waters of the region. But the story doesn’t begin and end there. With each project there is an arc. You know, the kind of arc your fourth grade English teacher taught you about, the arc of a narrative story…it kinda looks like a roller coasteror a mountain range… 

 

…kinda like a Pennsylvania mountain range 

But I digress…

A Classic Narrative

The story of how NPC conserves land is like a classic narrative in that it has a beginning, middle and an end. It’s never linear, and often it starts in the dark of night, on a Sunday afternoon, or in the middle of a rain storm.

There are many peaks and valleys, yes literally, but also figuratively. In the case of Kelley/New Garden, many players needed to play their part for the success of the acquisition. John Steinbeck couldn’t have made this stuff up!

A Cast of Characters

This story contains interesting characters whose paths cross and link through the acquisition of the land. County Commissioners, biologists, State Senators and Representatives, judges, lawyers and even a priest worked together to create communications and opportunities for the acquisition to move forward. Then there were the Kelley Estate heirs who had to agree to sell their portions of the estate in support of the partnership and conservation of the land, as well as the members of the West Keating Township community who used the land for generations to hunt, fish and at one time make their living. And last, but certainly not least, NPC’s director, Renee’ Carey and the Rocky Mountain Elk Foundation’s, Thom Woodruff, would work to partner with all of them to ensure the successful outcome of the project and the acquisition of the land. If I told you everyone who took part in the success of this acquisition, including NPC donors,  the list alone would be something like the opening of a JRR Tolkein saga!

The Climax

An aspect of the climax came when the Clinton County Courts deeded the property to NPC. The next step at year two in the acquisition project, was to transfer ownership of the property to the Bureau of Forestry and the PA Game Commission. The two state agencies would then work to decide how the property would be divided. Once these decision could be made the Conservancy and the Elk Foundation would begin to move forward with the sale. This would take another 2 years. Who knew where this story would end?!

A Happy Ending

For one week, in 1999, NPC was the proud owner of 4,200 acres of Clinton County Forest. A week later, the land was turned over to The Rocky Mountain Elk Foundation to help offset the insurance costs. Then in the summer of 2001, 3,100 acres were dedicated as State Game Lands 321, and 1,100 acres became part of the Sproul State Forest. A happy ending for a four year project.

Today the property is comprised of fields, woods, food plots, meandering runs, steep wooded side hills and 3 1/2 miles of river frontage along the West Branch of the Susquehanna.

There’s Always More to the Story

We hope you enjoyed this post, it is part of a series of pieces highlighting the stories of NPC’s work in the region. Until next time…

Leave the Deadwood

Interestingly many firewood gatherers focus on taking dead trees out of the forest. Research has repeatedly found that many of Pennsylvania’s privately-held forests could benefit from leaving more dead wood in place. Standing dead trees contribute important habitat for many wildlife species. Standing dead trees (snags) and dead parts of live trees offer both room and board for many kinds of wildlife. Tree cavities in live or dead trees are used by 35 species of birds and 20 species of mammals in Pennsylvania. Rotting and decaying wood on the forest floor provides cover and protection to many salamanders. At least 19 kinds of salamanders and 26 species of reptiles make some use of logs, stumps, bark, and slash piles in Pennsylvania’s forests. Ecologists believe dead wood is one of the greatest resources for animal species in the forest. (For more information on Dead Wood and Wildlife, visit https://extension.psu.edu/dead-wood-for-wildlife.

Cutting Live Trees

If deadwood is so important to wildlife, what makes good firewood? If you are thinking ahead and preparing firewood for next year, cutting live trees is really the way to go. By cutting live trees there is the opportunity to improve growing conditions for trees that remain. Individual trees in a forest compete for growing space to expand their leaf area. When tree crowns are “tight” up against each other and they move in the wind, they collide and, in the process, physically define their space – some trees gain more space and others lose. Understanding this, a firewood cutter can choose to provide space to a tree they want to improve by cutting a competing live tree.

Making decisions about which trees to leave involves many considerations. Note the point is which tree to leave, not which to cut. The tree left will continue to grow by increasing its crown area. A firewood cutter can “take the worst first;” leaving the best to grow. The tree cut might be selected by: crown condition, stem quality, defects, and species. Species is purposely last. A quick web search will find plenty of listings showing heat value per cord by tree species. Interestingly, all hardwood tree species have about the same number of BTUs per pound of wood – about 8,600. The important variable is pounds of wood per cubic foot, which can vary a lot. For comparison, a cubic foot of dry sugar maple weighs 44 pounds and basswood is 26 pounds. A pound of sugar maple has as much heat as a pound of basswood – you will need a larger volume of basswood.

Yes, we know this article is mostly handy for next year, and won’t help you get your wood pile in shape this year, but there are actually things you can start doing this winter that will make next winter warm and toasty!

Written by Jim Finley, Professor Emeritus, Forest Resources Management, Center for Private Forests at Penn State

University Park, PA – November 20, 2018 – After a long, hot, and, in some places, a wetter than normal summer, it seems autumn has finally arrived. Perhaps your thoughts are turning toward evenings warming in front of the fireplace or cozying up to the woodstove. The US Energy Information Administration estimates that about three percent of all Pennsylvania households depend on wood as a primary heat resource. Updated census data in 2017 found that there are nearly six million households in the state, meaning that about 170,000 homes use wood for heating; however, very likely many more use some wood to supplement their heating demands.

Preparing Firewood

Those folks who burn wood for heat know the mantra that it should be cut to length, split, stacked off the ground, and covered for at least nine months to be dry and ready to burn. Preparing firewood well in advance ensures that its moisture content will approach 20 percent. At this level of dryness, there are fewer issues with creosote formation in the flue, and this certainly reduces risks of chimney fires. As well, the heat gained by burning dry wood over uncured wood is significant. Clearly, there are advantages to thinking a year out if you gather your own firewood.

An important part of firewood preparation involves cutting to length and splitting. Doing this exposes more surface area, which enhances water loss from wood cells. Stacking is also important, as it promotes air movement across the exposed surfaces. Finally, covering, so air is free to move through the stack, keeps precipitation (think rain and snow) from continually wetting the wood.

The Risks of Gathering

Undoubtedly, many Pennsylvanians gather their own firewood on privately held forests or on state forests with appropriate permits. This is arduous work; but at the same time can be enjoyable. However, firewood gathering involves risks. A research paper published in Advances in Emergency Medicine analyzed nearly 116,000 chainsaw injures requiring emergency room visits between 2009 and 2013 in the United States[1]. They found that, “Most injury visits occurred among males (95%) and persons aged 30–59 years and during the months of September through November. The main body sites injured were the hand/fingers and knee.” If you are going to cut and move firewood, please make sure you understand how to use the necessary tools, always wear appropriate and approved safety equipment, and understand your personal limits and skills.

Biochar, A New Take on an Old Friend in Conservation

“If you could continually turn a lot of organic material into biochar, you could, over time, reverse the history of the last two hundred years.”   Bill McKibben, Professor, Middlebury College

 

What is biochar?

The short answer is charcoal. However, it is the creation of charcoal through a process called pyrolisis,  the slow burning of matter, such as hard wood waste, coconut hulls, or rice hulls under high heat. This charcoal applied to depleted soils increases topsoil nutrients for plant growth. This biochar becomes especially helpful in regions where soils have become depleted or toxic due to run off.   

Creating char is an ancient process found in large deposits in the Amazon Basin dating back at least 2,500 years. In its modern use, biochar not only has the advantage of cleaning soil and water, but also limiting, and perhaps reversing soil or water damage.   

According to the International Biochar Initiative, “biochar can convert agricultural waste into a powerful soil enhancer making soil, especially in at-risk regions, more fertile and thereby boosting food security, discouraging deforestation and preserving crop diversity.  Biochar is a very stable form of carbon and can last 100-1000 years in the soil. For each pound of biochar in the soil, 3 pounds of carbon dioxide are filtered out of the air.”  

Biochar’s Potential

Biochar might not sound like a very exciting term, but for Gary Gilmore, Woodland Stewardship Coordinator of the PA Department of Conservation and Natural Resources Bureau of Forestry, it is something to get excited about, as biochar has the potential to:  

  • Capture toxins and excess nitrogen protecting our waterways and groundwater quality  
  • Create an alternative energy source for generating heat and power, and valuable by-products of synthetic and bio-fuels  
  • Reduce the need for (and use of) fossil-fuels and fossil-fuel based fertilizers  
  •  Turn bio-waste into value-added products while creating jobs  
  •  Isolate CO2 safely for thousands of years  

Not a fertilizer

However, biochar is not a fertilizer, but a “soil amendment,” meaning that added to soil it allows nutrients to remain in the soil over longer periods. The porous nature of the biochar can hold up to 6 times its weight in water and beneficial soil bacteria. Application of biochar to soil creates more sustainable soil management and decreases nutrient loss.   

In addition to the way biochar builds up soil, it also has the capability of binding soil nutrients like nitrogen, phosphorus and potassium. This binding prevents nutrients from becoming run off into our waterways. According to the USBI, United States Biochar Initiative, “Biochar also holds gasses; recent research has proven biochar-enriched soils reduce carbon dioxide (CO2) and nitrous oxide (NO2) emissions by 50-80%.”   

As an ancient soil amendment, biochar is gaining traction in the study of soil maintenance around the world. Recently, the impact of this soil amendment has gained a foothold here at home as a part of Penn State’s short courses offered this fall.  As the study of biochar grows, we discover new knowledge about ancient wisdom that can address multiple environmental impacts on a local and global scale.

The Foundation will then “stretch” your donation using funds from the Alexander Family of Dealerships and others.

To make a donation during the event visit our online giving page at “Raise the Region.”  Please note, the link won’t work until 6:00pm on March 8, 2017 and will stop working at 11:59pm on March 9, 2017.

Ephemeral Forest Pools a.k.a. Vernal Pools

Vernal ponds are temporary wetlands that fill with water each Spring. They are seasonal breeding and feeding grounds for many amphibians, reptiles, insects, birds, and mammals. Some of these animals need the pools for breeding while others rely on them for food.

The word “vernal” comes from the Latin word for spring, vernalis.

Vernal ponds are formed each year in the late winter or early spring. A shallow ground depression fills with spring snowmelt, precipitation, and the rising water table. They are generally less than 40 yards in diameter and no more than 4 feet deep.

Feeding Birds Month is Wrapping Up

Feeding birds month is wrapping up. The last thing to think about is when to stop feeding birds. Dr. Brittingham notes that feeding into spring may allow you to see some migratory birds on their fly through, and the birds that are normal “PA residents” in the spring and summer, but leave for the winter.

She suggests you keep an eye on the area you’re using and if you start to see mold or mildew, to stop feeding, or change your feeding area. Typically in the spring there’s more moisture from melting snow and spring rain. Things might get moldy, and you’ll want to prevent it from becoming a problem.

She also states that if a bear visits your feeders, you need to stop feeding. Bears coming out of their winter hibernation are really hungry and your bird feeder is an easy source of yummy calories.

Penn State Extension and the Pennsylvania Game Commission both have resources to review about bears in general, with some information about bears and bird feeders.
