Preview of the 2019 Wetlands Job Report

Finding a Job is the most stressful part of graduating from college. The Dr. Suess book entitled “Oh, The Places You’ll Go” is given as a gift at many graduations. The problem is that, collectively, colleges do not prepare graduates with marketable training for a job AFTER college.

You expect to find a job in your major because that is WHY the money is spent, and soon you realize that the training is not there. Especially if you have a degree in environmental sciences.

You’d like to do something rewarding that is done outdoors os you don’t sit at a desk all day. However, you have no experience or training in a marketable skill.

The most common degree awarded to students studying Environmental Science is a bachelor’s degree. A roadmap designed to lead graduates with bachelor’s degrees in environmental sciences, ecology, geology, biology, etc., into an environmental career would reduce the stress of finding a job. Wetlands provide many careers for science degree candiates.

This white paper is written for graduates in the environmental sciences to show them how ot get the experience they need in the classroom and in the field and to be eligible to land a job working with saving the wetlands. Education/training in specific wetland duties should be part of a graduate’s resume on graduation.

A listing of job titles is included in this whitepaper as well as a listing of the most requested experience or exprtise for a job in the wetlands. It also includes a list of current legislation and polices driving wetland jobs.

The Swamp Stomp

Volume 19, Issue 13

Often thought of as vermin, beavers have been trapped and shot, while their dams have been destroyed by dynamite and bulldozers. However, the dry climates that have caused droughts throughout the West have brought beavers back to the forefront of landscape preservation.

By creating their dams, beavers raise the water table along rivers, which supports the tree and plant growth that stabilizes banks and prevents erosion. The dams also contribute to improved fish and wildlife habitats and encourage richer soil to develop. However, in the dryer parts of the country that have been suffering from severe droughts, the most beneficial contribution of beavers is the water their dams collect.

Before beavers were considered pests, the tens of millions of semi-aquatic rodents that dwelled in North America formed an integral part of the hydrological system. Jeff Burrell, a scientist for the Wildlife Conservation Society in Bozeman, Montana, described how important the beaver once was for environmental stability. He said, “The valleys were filled with dams, as many as one every hundred yards. They were pretty much continuous wetlands.”

However, by 1930 the beaver population dropped to less than 100,000—most of which dwelled in Canada—because of fur trapping. Since then the number of beavers has bounced back to an estimated 6 million, and an appreciation for beaver dams has begun to grow.

Lately, hydroelectric and reservoir dams have been heavily criticized because of the extensive changes they cause to the natural environment. The benefits of beaver dams, both natural and artificial, have, subsequently, become an attractive alternative. In fact, the demand for natural damming has risen so much over recent years that government agencies sponsor workshops on the West Coast to train wetland workers on how to attract beavers.

Burrell claimed that as long as beavers are able to help, we should take advantage of the resource. He said, “We can spend a lot of money doing this work, or we can use beavers for almost nothing.”

Beavers are the ecosystem’s natural engineers. Each time a family of beavers moves to a new territory, it begins a new dam in order to create a pond and shelter. As the water trapped behind the dam increases because of the buildup of twigs, mud, and stones, the entrance to the beaver’s shelter becomes submerged underwater and thus is protected from predators.

The new pond nourishes nearby willows, aspens, and other trees, as well as providing a safe place for fish that require slow-moving water. Land creatures such as deer, elk, and songbirds benefit from the grasses and shrubs that grow as a result of the pond.

The greatest benefit of the pond, however, is the increased levels of underground water. The boosted water supplies would considerably lower the groundwater costs for farming. Cheaper water preservation will be crucial going forward, especially in areas suffering from drought. Burrell claimed, “People realize that if we don’t have a way to store water that’s not so expensive, we’re going to be up a creek, a dry creek. We’ve lost a lot with beavers, not on the landscape.”

The danger of allowing beavers to dam streams freely is that their damming may cause floods in residential and urban areas; if unchecked beavers can be destructive to ecosystems that are not already short of water. Therefore, it is important to only encourage beaver activity in areas that need help managing and retaining water.

Beaver activity has been increased in arid climates such as those found in Arizona. However, the consequences of doing so are largely unknown. Julian D. Olden, an ecologist at the University of Washington, discovered that beaver ponds made in Arizona proved to be ideal habitats for invasive fish, such as carp, catfish, and bass, which will eventually overrun the native species. He concluded, “There’s a lot of unknowns before we can say what the return of beavers means for these arid ecosystems. The assumption is it’s going to be good in all situations, but the jury is still out, and it’s going to take a couple of decades.”

It appears clear that beaver activity is not recommended in all situations, but the positives of allowing beavers to dam water supplies in low-water-areas seem to outweigh the negatives. As mentioned by Olden, the overall consequences will only be able to be gauged after a large amount of time has passed. Until then, all we can do is hope that the positives continue to outweigh the negatives.

Pangolins are quite lovable and exotic creatures. They are solitary, shy, and nocturnal. Their size ranges from 12 to 60 inches and they are covered in remarkable scales. Not only do they have unique diets consisting of just a few specific types of ants and termites, but they also constitute their own taxonomic order. Their powerful tongues attach all the way to their sternum, making them even more intriguing.

What makes them even distinctive though unfortunately, is that among mammals, they are the most heavily trafficked non-human mammals. Between the years 2000-2013, an estimated one million pangolins were trafficked, with 67 countries and territories involved. There are many traits about pangolins that make them so coveted by humans. For starters, they make great bush meat and their meat is considered a delicacy in Vietnam and China. However, their most coveted trait is their scales. Their scales are used in traditional medical practices in China and some African countries, including Ghana, Nigeria, and South Africa. The keratin in their scales is what is sought after, and has been known to be of benefit for health problems such as lactation issues, arthritis, and rheumatism.

Although some African countries practice traditional medicine that uses pangolin scales, it is China where most shipments are sent. In China alone, there are approvals of 29 tons of scales yearly in the pharmaceutical business. In this business, there are about 200 pharmaceutical companies and 60 medicines that are produced using the scales.

This measure of trafficking hasn’t gone unnoticed by conservationists. In 2017, CITES (Convention on International Trade in Endangered Species) issued a worldwide ban on commercial pangolin trade. Before this, in 2000, trade of four of the eight species was prohibited. Despite these efforts, pangolin trade is still highly prevalent in the black market. Although officials cannot estimate how many are traded yearly, National Geographic estimates that hundreds of thousands of pangolins are killed each year for trade purposes.

The biggest issue in spreading the word about pangolin conservation is the pharmaceutical business’ “need” for pangolin scales. In the mid-1990s, China hunted pangolins into their seeming disappearance. There were stockpiles of scales that Chinese pharmaceutical companies gathered their needs from, but conservationists doubt that those stockpiles would still be meeting their needs two decades later. Still, even though the scales are coveted greatly in traditional medicine, there is no scientific proof that the scales even have positive effects when used medicinally.

Chinese companies, licensed by the Chinese government to do so, have tried to breed pangolins in captivity for commercial purposes and to keep them out of the trade. However, pangolins are arduous animals to keep in captivity simply because they stress easily, so efforts have not been successful. On top of the difficulties of pangolin captivity, several Chinese companies that try to breed pangolins were raided since authorities were suspicious of their motives. Even though they are trying to do good by keeping pangolins out of the trade and in their own hands, they should instead try and eliminate the use of pangolin scales altogether.

Education is the biggest help to pangolin conservation. There is no scientific proof that pangolin scales have any effect when used medicinally, and there are many known alternatives to the scales. Since breeding them commercially would be a nearly impossible effort to pursue, educating about alternatives in the world of pharmaceuticals could make the biggest impact.

There have also been some groups that have been quite successful rescuing pangolins found in the trade and nursing them back to health to be released. The Tikki Hywood Foundation is a renowned wildlife rescue center that was founded by Lisa Hywood in 1994. They are based in Zimbabwe and have rescued nearly 180 pangolins from illegal trade since 2012. Save Vietnam’s Wildlife is another renowned organization. They are a non-profit rehabilitation group that also takes a big part in pangolin conservation. In 2017, they rescued 407 pangolins. Because of these groups, and several others, many pangolins have had a second chance at life in the wild, free from capture and the dangers of trade. Aside from rehabilitation programs around the world, many organizations (like Save Pangolins and Pangolin Conservation) have helped to raise money to help educate people about why there is a need for pangolin conservation and rehabilitation. With further education about this cause, pangolin trade can hopefully disappear completely from around the world.

The Swamp Stomp

Volume 19, Issue 9

The use of a survey grade level is critical for obtaining accurate measurements of various biological features, biological benchmarks, etc.  This information is used for many purposes including stream restoration, coastal restoration, wetland restoration, and other design purposes.

There are two types of levels used for construction and design. The older of the two is known as the Dumpy level. This level is like a spotting scope with crosshairs. It is highly accurate (despite its name) and also has an added advantage of being able to measure distance. However, it does require much more work to operate and is limited to a range of about 30 feet.  It also requires two people to operate.

Laser levels are the other commonly used measuring tool and are a great improvement over the Dumby levels. The major benefit is that the distance away from the level is pretty much as far as you can see.  This reduces the number of station moves and speeds the process along.  You also only need to have one person to operate the level.

There is a third option which is to use a surveyor total station. This, however, is a very complicated process and usually beyond the level of detail needed for most biological assessments.  A corollary to this is the use of GPS.  GPS is great for x and y coordinates, but it is often meters off on the elevation (z).

Laser Levels

You do not need to spend a lot of money to purchase a quality laser level. You can often find these for sale in big box home improvements stores and hardware stores.  They are around a couple of hundred dollars.  You can also rent one from a survey supply shop for about $20-$30 per day.  They will also be happy to sell you one if you need to use it more than just a few times.  Survey grade levels are usually in the $500 to $1000 range.  This is worth the investment if this type of work is a regular thing for you.  Also, do not cheap out on the box.  The level will get bounced around so you will need a quality instrument case.  This is sometimes a problem with the home center levels.

The laser receiver is usually included with the laser level.  This is a little box that attaches to the survey rod with thumb screws.  It takes batteries and makes a tone when the laser beam from the level hits it.

You also need legs. The level should be placed upon a quality tripod. This is not the same type as you use for a camera. Survey grade tripods are usually made of wood or aluminum and have steel spikes to set it into the ground.  The legs are adjustable so that you can level your level. The level should be about chest high when mounted so the tripod needs to be 4-5 feet high when set up.

Next on your shopping list is a survey rod. You want to get the smallest rod that will serve the purposes of the site work you are doing. A 12-foot rod is much better than a 25-foot rod if you only need to go up a few feet. The bigger the rod the more sway you have and the measurements will be less accurate. However, if you have a steep slope on your site a bigger rod may be necessary.

You will also need a measuring tape or carpenter’s rule.  It is better to get one that is calibrated to 1/10’s of a foot rather than inches.  The survey rod is almost always in 1/10’s of a foot, however, make sure you are not using some sort of metric rod.  That really clean rod in the back of the tool closet that nobody uses might be there for a reason.

Set Up

The first thing that you want to do is take a walk around the area that you need to survey. You want to find the best place to set up the level so that you do not need to move it more than necessary. Keep an eye on slope, trees and other obstructions.  The level needs a clear line of sight. You can clear some of the vegetation away, but it is usually easier to find a spot that would require the least amount of work to get your shots. The tripod should be set up above the highest point you are going to survey. You need to include the height of the level receiver on the rod when you are making this estimate. This translates to about 5 feet above your highest point. The level needs to be able to “see” the receiver.  If the level is set is too low it will shoot below the receiver mounted on the rod.  You can move the receiver down, but that would require that you recalculate for those shots.

Keep the level in the box until you are ready to place it on the tripod.  Do not attach it to the tripod and then walk around with it.  It should be boxed when moving it around the site.

Set the legs up on as level a surface as you can. Adjust the legs so that the level mounting plate is fairly level. You can use a hand level to do this or the bubble level on the laser level itself.

The laser level attaches to the tripod by way of a large screw below the mounting plate. Do not tighten this too much until you have leveled the level. There are three or four leveling screws on the level. There is also a glass bubble level on the mounting plate. Adjust the leveling screws so that the level is dead on the level in all directions. This will require that you spin the level around and make adjustments. If you have attempted to level the tripod before you mounted the level, this will go fairly quickly.  It is critical that the level is mounted level. Otherwise, your data is junk.

Instrument Height

There is usually a marking on the level where you should measure downwards to the ground. We are also going to determine the height of the instrument using the back site, but you should always measure the distance from the instrument to the ground. We don’t really use this data, but it seems that it is always done. It is sort of a cross check.

Backsight

You should place a project benchmark somewhere near the level set up. This serves as your project control and can be surveyed for real later if you need to derive actual elevation points from your level runs. This control should be set using a pin, rod, pipe or other relatively permanent makers. Wooden stakes do not work as they can be easily removed or damaged.

The backsight elevation is any number that makes sense. The convention is to set it at 100.  You may come back later in drag control onto the site to determine the actual elevation, but that is not necessary for this type of work.

The laser level indicator should be attached to the rod, usually at the tip. Note the location of the indicator. For example, it is on the rod at 4.5 feet.  Most telescopic rods have a height indicator on the back of the rod.  As you raise the rod the height indicator numbers will change.  Be careful to raise the rod in the proper order.  This varies with some rod types so be sure to check with the manufacturer on the use of the rod.

A Direct Elevation Rod or a “ Lenker Rod ” is the most common type and has numbers in reverse order on a graduated strip that revolves around the rod on rollers. Figures run down the rod and can be brought to the desired reading—for example, the elevation of a point or benchmark. Rod readings are preset for the backsight, and then, due to the reverse order of numbers, foresight readings give elevations directly without calculating backsights and foresights.

Turn the laser on and position the rod on the benchmark and raise the rod until you hear a steady tone. You will usually hear a slow chip when you are just below the laser beam and a fast chirp when you go past it.  Note the rod reading. That is your backsight reading. Add the elevation from the benchmark rod reading and you have your height of instrument (HI).

For example, your benchmark is elevation 100.  Your rod reading on that benchmark is 4.06.  Therefore, your Height of Instrument (HI) is 104.06’.  Your benchmark elevation should be lower than the instrument ground location.  If not, you need to adjust the detector and do some more math. It can be done, but it takes more time.

Now you are ready to go to work on the foresight.

Position the rod directly on the ground at each feature shot. The rod should be straight up and down. There are plumb levels you can attach to the rod to help you.  Some laser detectors will also beep at you if you are too far out of plumb.

Raise the rod until you hear that steady tone. Note the rod reading. Make sure that you raised the rod in the right order and that the numbers are being read correctly.  Usually, this is a matter of checking reality.  If your rod reading suddenly jumps by 5 feet from the last point you may have raised the rod sections in the wrong order.

Record each feature and provide some notes.  A level book works great for this.  This is an example of a level book set up.

Set  Up  1

Station	BS	HI	FS	Elev	Notes
(feet)	(+)		(-)
	4.06	104.06		100	Benchmark
			6.63
0+25				97.43	MT
			5.35
0+50				98.71	MHW

At each feature subtract the foresight (FS) from the Height of Instrument (HI) to derive the elevation.

In this example, we have a 1.28’ difference from mid tide (MT) to Mean High Water (MHW).  We can, therefore, assume that our total tidal exchange would be 2.56’ from Mean Low Water (MLW) to MHW.

We would need to check many other points. Usually, for a biological benchmark survey, we would to stationing along a cross-section.  Each feature would be relative to the feature type and its location on the cross-section.  In our example above, the distance from the MT to MHW is 25’.  This is measured by setting a fixed starting point at 0+00 and measuring along that line.

If you need to move the level you will need to calculate a new HI.  Make sure to reference the setup with the data.  Start a new table for a new set up.

Finally, if you need to determine the real elevations of your features survey the benchmark. This will require a surveyor to locate nearby elevation control and drag that onto the site using traverse lines. You can also use high-end GPS for this.  In our example above the real elevation for the benchmark is 456’ NAVD 88.  Our new HI is 460.06.  We need to make sure we cite the vertical data source. In this case, it is North American Vertical Datum of 1988 (NAVD 88). Therefore our MT is 453.43’ NAVD 88 and the MHW is 454.71’ NAVD 88. You can do this for all of the data associated with the benchmark.

One final note of caution

If you are doing level runs for design purposes, you may or may not need a licensed land surveyor to sign off on them.  However, if you are doing any floodplain calculation work you will most likely need the help of a licensed surveyor. Some jurisdictions allow licensed professional engineers to do this as well. This is a matter of state and federal law so be careful and ask questions.
