2018 Soil Auger Buyer’s Guide

The Swamp Stomp

Volume 18, Issue 33

Wetland Soil Augers

One of the most frequently asked questions by our wetland delineation students is, “what type of soil auger should I buy?”

A quick browse through any of the forestry supply companies catalogs and you are quickly overwhelmed. Who would have thought that there we so many different types of soil augers? Some of them are quite expensive. Many are modular and you end up buying part of an auger and have to order more parts. You do not want to drop a grand on an auger only to find out it is not what you needed or expected.

To help you get a handle on this I have put together brief pros and cons of the most common soil augers used for wetland delineation. This list is based upon my personal field experience with these augers. Each has its place so be prepared to buy a few. I do have a favorite all around auger which I will also cover, but I own a bunch.

Tube Sampler

This is a favorite for the beginning wetland delineator. One of its biggest assets is it is the cheapest. However, it has limitations. The basic construction is a simple tube that is cut open at the bottom. There is usually about a 16 inch half pipe slice that is used to examine the soil profile in-situ. The very end is a ring that everyone gets their fingers stuck in. A good one is about 24 inches in length with an opening extending about 16-18 inches. There is a short t-handle on the top. Sometimes this is detachable with a screw fitting. Others have the handle welded on. The former is a bit more expensive.

One of the biggest advantages of this type of auger is the small footprint it makes. In glacial regions, it is sometimes the only auger that can get in between the rocks. It is also very handy for quick assessments.

The biggest disadvantage is the relatively small amount of soil sample this auger extracts. Oftentimes, it just is not enough sample to make a wetland determination. Small rocks are also a problem as they will plug up the tube end. The issue of cleaning it the sampler end out is also a challenge. Don’t stick your finger in the end. It is sharp and just the right size to get your finger stuck. Use a stick to clean it out.

Screw Sampler

This auger looks like a giant corkscrew. The screw is about a foot long and is about 2-3 feet in total length. The screw is usually attached by extension bars that can be added to achieve a comfortable length. It has a slightly larger footprint than the tube sampler and is similarly useful in glaciated regions.

The biggest challenge with using this auger is the ability to measure the thickness of a hydric soil feature. The screw blades are about .5 inches thick. This results in a stretching of the soil sample. It is hard to estimate how thick a feature may be using this auger. It also provides a very small about of soil sample.

Bucket Auger

 

This is probably the most common type of auger used by soil scientists. Not necessary wetland delineators, however. The basic design looks like a coffee can with one end open and the other end has two blades welded onto it. An extension bar connects in between the bucket and a t-handle on the top. All of these items can be customized to fit the user’s needs.

If you are just starting out delineating, you will probably be handed one of these bucket augers. There always seems to be one hiding in a closet in the office. Someone bought it, used it once and there it sits.

I do not have a lot of pros to offer with this type of auger. The biggest problem is that it grinds up the soil profile making it very hard to distinguish the hydric features if the soil. It also requires that once you auger down and grab a sample you then have to tip the bucket upside down and bang out the sample. This also obscures the features.

Soil scientists like these augers because they are trying to obtain a discrete sample at a specific depth. This is usually why the extension bars are so long. I have seen some augers used in the field that were over 6 feet long. This is very hard to use if you are 5’6” tall.

Dutch Auger (My Favorite)

This auger was made for wetland delineations. It is a double blade at the end of an extension bar and t-handle. It cuts a very nice sample without disturbing the profile integrity. You can usually auger down several feet fairly easily and lay out the samples in more or less the same way they would be found in the pit. You also get a decent amount of sample to play with.

There are a number of brands and styles of this type of auger. The biggest difference between the individual styles is a represented by the size and pitch of the blades. The original use of the Dutch auger was for muddy soils. However, there have been many modifications to the design and there is such a thing as a combination auger that works well in loamy soils as well as mud.

Sharp-Shooter

 

This is also known as a tree planting spade. It is simply a shovel that is 4 inches wide and 16 inches long. It digs a small hole and cuts a nice sample. In a pinch, this shovel will work in almost any circumstance.

The biggest advantage of this sampler is the cost. You can pick one of these up in your local home improvement center for about $25. Most of the other augers mentioned are well north of $200.

The biggest downside to this device is the work associated with it. Digging a hole is a lot of work. You get a nice amount of sample and you can even cut a nice sidewall to see the profile. However, this took a lot of work.

Quick Connect or Not

 

One last note on the issue of quick connects. To be frank, I have yet to see one of these work once they were put into field use. The fittings get gummed up with dirt and the quick connects jamb. I would suggest going with an all welded design. You are not going to take these apart anyway so why spend the extra money. If you need to travel by airplane, TSA is not going to let you carry these on so there is no need to break them down. Just check them or better yet, buy a shovel for $25 when you get to the job site.

Project Puffin

Swamp Stomp

Volume 18 Issue 32

Forty-five years ago, Stephen Kress had a goal: restore Atlantic puffins to the Gulf of Maine. While many believed that nature should be left to “take its course,” Kress devoted his life to making this goal a reality. Through the creation of the National Audubon Society’s Project Puffin, Kress was able to restore more than 1000 nesting pairs to three Maine islands and earn the title, “The Puffin Man.”

Island stewards, also called “Puffineers,” are the backbone of Project Puffin. These interns live on Eastern Egg Rock, one of the Maine islands where puffins have been restored. During the breeding season, they record details on the puffins and their behaviors. The island stewards live minimally during the 10 weeks from June to August in tents, with food and water brought to the island every two weeks. Their work has been critical to not only re-establishing Atlantic puffins to their former nesting places but also in providing data on climate change. The warming Gulf of Maine, which has warmed faster than any place on Earth except for an area northeast of Japan, has caused a change in the diets of puffins. For instance, haddock was never part of puffins’ diets prior to 2010. But in 2017, haddock made up 14% of puffin chicks’ diets on Seal Rock and 6% of their diets on Eastern Egg Rock. The warmer water has caused fish like haddock to move from their more southern environments to northern environments like the Gulf of Maine. Not only does this affect the diets of puffins, but it affects the prior and current ecosystems of the haddock. More haddock in the Gulf of Maine means more competition for the fish that already live there, which could be a serious problem for these fish populations. Moreover, the data that has been amassed over four decades on this by these island stewards is instrumental in understanding the effects of climate change.

Project Puffin is so much more than data, however, to the interns that work on Eastern Egg Rock. Project Puffin has not only given Atlantic puffin populations a second chance, but it has also opened up opportunities that have shaped the lives of the interns involved. Kevin Bell helped bring puffins from Newfoundland to Eastern Egg Rock in 1975, and today he is the CEO of Chicago’s Lincoln Park Zoo. Nicole Faber, who has been working on Eastern Egg Rock for three summers says, “It’s incredible to live at the pace of another species. We’re following the birds and what they do. It’s not something you normally do in life. There are so many things we are shut off from, but we have to respond to the birds. It’s a good thing. You have to be OK sitting with yourself in your own brain.”

In more ways than one, Project Puffin is a story of success. Stephen Kress reinvented the future of the Atlantic puffin whilst furthering the passion so many have for protecting our planet.

First there was Fracking, then came Re-fracking

Swamp Stomp

WM

Volume 18 Issue 31

Many people in the United States believe that hydraulic fracturing, better known as “fracking” is a relatively new technique used to help extract oil and gas trapped in layers far below the Earth’s surface. For the most part, they are correct. Modern fracking used in combination with horizontal drilling was only introduced in the 1990’s and with great success. But the history of fracking has a much longer and richer history that can trace its roots back to the 1860’s and the Civil War.

Back in 1862, Lt. Col. Edward A. L. Roberts, a Lieutenant Colonel of the 28th New Jersey Volunteers, had the idea of opening underground oil-bearing cracks and crevices by the introduction of explosives. He eventually received one of many patents on a device he called the “exploding torpedo”. In his process, a long, thin, iron tube packed with black powder was lowered into a borehole. It was then back-filled with water to concentrate the explosive force downwards and detonated. Production in some wells improved by more than 1200%!

Through the years this technique continued to be successfully used and improved upon with further increases in production. Then in 1947, the first use of hydraulic fracturing, the introduction of pressurized fluids, was demonstrated in an oil field in Kansas, where 1000 gallons of napalm were injected into a limestone formation. There was little increase in production at the time, but this modest beginning led to further work with different materials and techniques and within a decade, 30% increases in oil production and 90% increases in natural gas production were common.

Then, in the 1980’s, companies began experimenting with combining the fracturing process with horizontal drilling techniques and by the 90’s modern fracking began to thrive. Previously unproductive wells were now producing and new formations, up until now, mostly inaccessible, began to produce in abundance. Some of the more notable formations are the great Bakken oil shale fields of the northern US and Canada and the Marcellus and Utica formations in the East. The USGS estimated the recoverable oil in the Bakken to be 3 to 4 billion barrels and possibly up to 7.4 billion barrels of yet to be discovered oil and more than 6.7 trillion cubic feet of natural gas. In the east, a new report by the Colorado School of Mines’ Potential Gas Committee (PGC) finds the Atlantic region — which includes the Marcellus and Utica shales — has the most promising natural gas potential in the country at more than 1,047 trillion cubic feet!

So, why do we need “Re-fracking”? Re-fracking is the practice of returning to older shale oil and gas wells that had been fracked in the recent past to capitalize on newer, more effective extraction technology. Re-fracking can be effective on especially tight deposits – where the shale produces low yields – to expand their productivity and extend their life. Wells sunk as little as three years ago and fracked until yields fell too low to be worthwhile are now being re-fracked. With wells costing many millions of dollars to drill and complete, it makes sense to return to see if new technology can extend their life. Most re-fracking success has been with vertical wells but an increasing number of horizontal wells show great promise. According to an analysis by the Los Alamos National Laboratory, on average just 13% of the gas from any given US shale is recovered. The potential for re-stimulating existing wells is therefore huge.

It is believed that over 90% of existing wells have undergone some form of fracking. Though there are health and safety concerns involving fracking, it is hard to argue with the results. Because of fracking, the United States has moved from a net oil-importing country, back to a net oil-exporting country. A recent concern, at least for natural gas, is that overproduction has lowered the price of natural gas to historical lows. While good for the consumer, it is not necessarily good for the producers who have had to cap off existing new wells due to oversupply (along with the inadequate infrastructure to get the gas where it is needed most.) The fact that fracking is now such an efficient process has allowed companies to continue to make money despite the abundance of natural gas in the marketplace.

There is no doubt that fracking and re-fracking are tremendous tools that will continue to benefit our country and the companies that produce our oil and gas. At least for the present, we can’t do without them. Let us hope that in our effort to become energy independent that we are mindful of the negative effects of this technology as well, and not sacrifice the health and safety of our nation’s people or our beautiful country from which we harvest these products. Do you think the pros of fracking out way the cons? Please comment below.

Peter Grande – Part of Nature’s Greatest Show on Earth

Swamp Stomp

Volume 18 Issue 30

If you’ve ever driven our country’s major highways, you have most likely come across a few of the world’s more interesting phenomena. Billboards the size of an Imax screen exclaim, “Come and see the world’s largest ball of yarn, the world’s tallest Tepee, (or one of my favorites), world’s largest cherry pie!” Well, not to be outdone, Mother Nature has put in a bid for a “worlds largest” recognition but you won’t see it on any billboard because it only occurs every 3-10 years on average, and even then, it’s only visible for about 24-48 hours. It’s hard to plan to advertise when you don’t know the exact arrival date, about as hard as predicting the birth of a baby.

So without further ado, Mother Nature proudly presents, “The World’s Largest Flowering Structure (inflorescence) on Earth, the Amorphophallus titanum!” AKA “The Corpse Flower” because of the smell it produces, and the less descriptive name, Titan arum. This unique plant is native to the rainforests of western Sumatra, Indonesia, on steep hillsides that are 120–365m above sea level, but it has also been successfully propagated over 570 times around the world since 1889.

The Titan Arum grows from the world’s largest known corm, sometimes weighing up to 220 lbs. (100kg). During the non-flowering years, a single leaf, the size of a small tree, shoots up from the corm. This leaf branches out into three sections with each of these sprouting more leaflets. Each year, this shooting leaf dies and a new one grows in its place. After many years, the plant finally gathers enough energy to bloom. But when it does, it goes all out, producing the largest unbranched inflorescence in the plant kingdom, ranging from 1-4m tall.

This past July the author was part of a large crowd of onlookers who were able to witness the rare bloom of “Peter Grande” at the Plant Delights Nursery, Raleigh, NC. One way of keeping track of Amorphophallus clones is to name them, hence, “Peter Grande”. Other names of specific plants include The Amazing Stinko, Carrion my Wayward Son, and Pewtunia! Who knew Botanists had such imagination?

Once the “flower” appears, a not completely understood process that includes powerful waves of olfactory-battering scents reminiscent of decaying flesh begins the process of pollination. According to the Chicago Botanic Garden’s blog, an analysis of the stench found that it consists of dimethyl trisulfide (also emitted by cooked onions and Limburger cheese), dimethyl disulfide (which has an odor like garlic), trimethylamine (found in rotting fish or ammonia), isovaleric acid (which also causes sweaty socks to stink), benzyl alcohol (a sweet floral scent found in jasmine and hyacinth), phenol (sweet and medicinal, as in Chloraseptic throat spray), and indole (like mothballs). This potpourri of chemicals is assumed to attract pollinators to the plant that they make their way down to the bottom of the inflorescence, deposit pollen on the stigmas, and then remain with the plant for about 24 hours before departing. If successfully pollinated, numerous red fruit, often called berries, are produced. Since the plant draws large amounts of energy from its corm as the seeds develop, eventually the plant dies. Should pollination not occur, the plant survives and begins the process all over again.

Mother Nature has produced a truly amazing plant, but one that is known to be vulnerable to extinction. The rainforests of Sumatra are under massive threat of deforestation, as vast areas are logged for timber and to make way for oil palm plantations. It is estimated that Indonesia has now lost around 72% of its original rainforest cover, and the scale of deforestation is continuing at an alarming rate.

We are fortunate botanists have been able to cultivate this rare species in greenhouses around the world and we owe our thanks to nurseries like Plant Delights, for helping assure that people in future generations are able to witness this wonder of nature.

The Pros and Cons of Seattle’s Plastic Straw Ban

Swamp Stomp

Volume 18 Issue 29

The banning of plastic straws has been a topic discussed frequently in environmental circles. As of July 1st, this became not just a topic for discussion, but a reality for Seattle, Washington, which is now the largest city in the United States that has banned the use of plastic straws. This may seem like a simple act, but it has had major effects on companies and people around the country, for better and for worse.

The ban on plastic straws may be a major win for the environment. Zoos around the country have been encouraging visitors to say no to straws, and some have even had bans on straws for years. This comes from the realization that plastic straws are a major contributor to the enormous amount of waste that finds its way our oceans. One study found that 8.3 billions of plastic straws have made their way to beaches around the world. Another study found that plastic straws make up 7 percent of America’s total plastic waste. By eliminating plastic straws from the trash we create, we really are doing the environment a great favor. However, this ban is not as simple as it sounds.

Restaurant chains such as Starbucks and McDonalds have promised their customers that plastic straws will no longer exist in their stores in the coming years. While this is great news for the environment, as these stores serve billions of customers, this is terrible news for people with disabilities. Many people have disabilities such that their jaws are not strong enough to drink without a straw, perhaps they cannot lift their heads the right way to drink without a straw, or they have are unable to use their hands to hold a cup in any way. Taking away straws takes away their ability to drink anything at all. Some supporters of banning plastic straws have considered this and suggested that these people may be able to use metal or paper straws instead of plastic straws. While this is a solution for some, others need the flexibility of a plastic straw. Dianne Laurine, a Seattle resident who has cerebral palsy, admits that plastic straws were truly life-changing. Her caretaker, Bill Reeves, states that before plastic straws there were rubber straws and these, “ended up being disgusting, and hard to clean.”

So, what is the solution? Should we ban plastic straws to save the oceans from tons of waste at the expense of a portion of our population? Or should we just ignore this topic altogether in order to reduce the burden on people with disabilities? The key to the solution may be to at least limit their use whenever possible. Banning plastic straws completely may not be the solution, but encouraging those who can, to skip using straws may help. Plastic straws are an easy piece of trash to remove if you are able to drink without one, which is why this movement has become so popular. However, there are many other plastic items that could also be removed from the trash we accumulate. Plastic bottle caps, for instance, account for 17% of America’s plastic trash, 10% more than plastic straws. By skipping drinks that come in plastic bottles, an even greater amount of trash can be reduced. Darby Hoover, a senior resource specialist for the Natural Resources Defense Council, states, “The key is breaking habits. Is something a habit because you truly need it or because you got used to doing it that way?” For some, plastic straws may simply a wasteful habit that can be changed and benefit our environment at the same time.

Climate Change

Swamp Stomp

Volume 18 Issue 28

The average global temperature has been rising at an alarming rate for about two centuries now. Of course, this is not the hottest the Earth has ever been; during the time of the dinosaurs, the levels of CO2 in the atmosphere were much higher. One does have to consider though, how hot our planet can become while remaining habitable for humans.

The Industrial Revolution, beginning in the early to mid-1800s, started at a faster rate of climate change also known as Global Warming. As our global society has grown more technologically advanced, our reliance on fossil fuels has raised the level of CO2 in the atmosphere. The pre-industrial revolution CO2 level was about 280 parts per million. During the Industrial Revolution, coal began to be used as a fuel for machinery. The introduction of oil and gas later on also contributed a large number of emissions, especially in the 20th century.

Global temperature has risen a good amount within the past century especially, but global warming as a term may be misleading to some. Bringing a snowball to the Senate does not prove global warming false. Global warming leads to more extreme weather, such as an increase in the number and severity of hurricanes, and even winter storms. It also has a more gradual effect. Glaciers and ice caps are melting in warmer times of the year and at a faster rate than normal, and the colder times of year are not enough to make up for the damage. The average temperature of our oceans, which absorb much of the increased heat, have risen by about .3 degrees. Considering the fact that oceans cover over 70% of the earth’s surface, that represents an enormous amount of energy being absorbed.

In recent years, many governments have put measures into place to reduce their carbon footprints. This has helped lead to a slow-down in the rate of global warming, enough so that many people have called it a “pause”. This is incorrect because the global temperature is still increasing, albeit at a slower rate.

Around 2036, the level of CO2 in the atmosphere will reach 560 parts per million, double the Pre-Industrial Revolution level. This will cause the world to cross a climate threshold, leading to even greater environmental issues. The slow-down may give us a few more years to correct our behaviors, but only a few.

The slowdown in the rate of global warming shows us that although we may not be able to totally reverse the damage we have caused; our efforts thus far have not been in vain. Now is the time for radical changes in policy. As individuals, we can do our best at reducing our own emissions and make more environmentally sound decisions, but it can only go so far. It’s time we held governments and corporations to the same standard we hold our citizens. We need to move toward clean energy as a society, and quickly. At this point, the possibility of making Earth uninhabitable for humans is not a matter of if, but when.

Parrots in Peril

Swamp Stomp

Volume 18 Issue 26

“Endangered species” probably brings to mind an animal or plant that is not often seen. Perhaps the giant panda comes to mind or the whooping crane or something else that lives far away. However, some endangered species are closer than you might think. Many species of parrots, for instance, are seen often in pet stores. Yet, they have become increasingly endangered in recent decades. The illegal parrot trade has brought about the near extinction of many of the 350 species of parrots and will continue to do so if not somehow stopped.

In the United States, around 99 percent of parrots in pet stores are captive bred. Because parrots are now considered an endangered species, this is desirable in order to reduce the number of parrots that are removed from the wild. However, Donald Brightsmith, a zoologist at Texas A&M University, says, “if you’re in Peru, Costa Rica, or Mexico, the chances of it being wild caught are 99 percent,” when buying a parrot. Moreover, in order to prevent further population destruction of these parrots, a way needs to be determined to distinguish captive-bred parrots from wild bred parrots.

Now, captive bred parrot chicks are given a metal band that rests around one of their legs for their entire life. However, illegal parrot traders have been able to make their own metal bands for wild-caught parrots in order for them to appear captive bred. In South Africa, geneticists have come up with a possible solution to this problem. At the University of KwaZulu, a gene profiling method is being developed that will allow breeders, pet buyers, or airport inspectors to determine if the parrot is captive bred by using distinct genetic profiles. Additionally, a method using chemical isotopes is being developed to determine the parrot’s diet, which points to where the parrot originated.

Although the rampant illegal parrot trade may make parrots’ futures seem grim, there have been recent improvements. For instance, Saudi Arabia and the United Arab Emirates have publicly stated that they will no longer import wild-caught African gray parrots, a species of parrot that has faced increasing danger. Additionally, the Puerto Rican parrot population, which consisted of 13 parrots in the 1970s, now consists of several hundred due to the efforts of biologists. Hopefully, as long as these efforts continue, the parrot populations may be able to avoid reaching extinction.
