Water: What’s in yours? Gov’t Agencies Address the Issue

Government agencies have a huge stake in the NYC Water Supply.  There are many government agencies impacted by the Surface Water Treatment Rule (SWTR) including the Environmental Protection Agency (EPA), New York City Department of Environmental Protection (NYC DEP) and the New York State Department of Environmental Conservation (NYS DEC).  The EPA is unique because it does not have one set procedure for protection of New York’s water supply.  In 1993, the EPA accepted a waiver from NYC from filtration of the water coming down from the Catskills.  The reason behind NYC’s request was because of cost.  The EPA also added over 150 conditions, in a compromise.  The conditions were mostly watershed protection and reservoir monitoring matters.

The NYC DEP issued a harder approach for farmers, homeowners, and businesses in response to this action by the EPA.  Residents of the towns where the reservoirs were located felt alienated by the act and felt that urban NYC was going to stunt their slowly growing economy by placing additional restrictions on local upstate residents.  In 1994, a coalition representing 34 towns provided so much support that NYC was unable to put their agreement with the EPA in effect.

In 1997, the Watershed Memorandum of Agreement came into play.  This Memo attempted to please all parties and has placed restrictions on NYC with use of eminent domain.  It also says the city will spend greater than 1.2 billion on infrastructure improvements.

Since the Safe Drinking Water Act of 1974, the EPA has regulated water so that it is safe to consume.  After the Surface Water Treatment Rule, the NYC DEP has made sure that water is filtered, and if it is not there must be several safety measures taken to make sure it is also safe for consumption.

Taking these rules into consideration the government has an obligation to protect the people from hazardous chemicals that may be found in the waters.  With New York City, one of the world’s most important cities, at risk, this matter is serious.  The question of who is to blame and who must pay for all this regulation is what the hoopla is about.  Should the city fit the bill or is it the Federal Government’s responsibility?  Both governments have large roles; the city has the more important one, however.  In many studies done, most people would say the water is safe to drink in NYC.  Because of the Watershed Memo Agreement, many stakeholders had to compromise.  Ultimately, the health of New York City residents must have to come before any profits or development is to be made on these lands.

Let’s Start Gardening… Rambunctiously

How can we address the problems with our environment?  What strategies are best for all parties involved?  Emma Marris tries to provide the reader of Rambunctious Garden with answers.  The simple answer is that in order to have well serving ecosystems all parties (owners, managers, and government) need to come up with common goals.  Marris goes on to list seven goals we must keep in mind as we go forward.

Goal one is to protect the rights of other species by realizing what Nauss calls “deep ecology” and connecting that to the intrinsic value of nature.  The main view is that humans must reduce their intensive impact on the Earth.  This view can be seen in two ways: 1. Letting a species live and survive on its own, 2. Buying ammunition so that a certain species will not eliminate other loved species.

The second goal Marris points out is protecting charismatic megafauna.  These are the beautiful wild animals that we have come to love by viewing the Discovery Channel and going to zoos.  The World Wildlife Federation has held responsibility in this field.  Animals we are aiming to protect include whales, dolphins, gorillas, tigers, and pandas.  One large population that is under the threat of poaching is the African Elephant.  In fact, the only place where the elephant is not threatened is in South Africa.  Ironically the population is getting so large that the organization has resumed culling the largest land mammals.

Goals 3, 4, and 5, deal with slowing the rate of extinction, protecting genetic identity, and creating biodiversity.  One of the greatest pieces of environmental legislation is the Endangered Species Act of 1996.  This piece of law has protected numerous species by placing them on that list and this leads to certain problems.  Specific species are incorrectly classified under genus, therefore are never even considered an endangered species, even though they might be.  Scientists can share the blame because they have failed to identify certain species.

Maximizing ecologic services and protecting the spiritual and aesthetic experiences is what sums up the goals for Marris.  She brings up the Sandhill crane on the Platte River in Nebraska.  Every March these cranes land in the river and spend some time before heading up north to Canada.  Due to industry, however, the river has been altered in many ways and humans have had to use heavy machinery to clear space for these marvelous birds.  Through human intervention the cranes have made a positive impact on the ecosystem.

All these goals may seem unrealistic to any person who does not care about the environment.  Many Americans go through their day without thinking about these things.  Marris realizes that and says that the only way for change to come about is if parties involved make complex compromises.  One key aspect is keeping green, open land undeveloped.  A great example to follow is the Hawaiian Ahupua’a.  We need certain wedges in our environment to be restored to the peak of human use and even restored to the era of early European contact.  We need a rambuncious garden.

 

Designing a New Conservationism

Emma Marris uses the concepts of ‘Designer Ecosystems’ and ‘Conservation Everywhere’ to illustrate her perspective of what humans should do about nature.  Her book, Rambunctious Garden, says it very clearly.  Human beings should not reserve nature for a closed off section in the wild, but rather incorporate the wild into their everyday lives.  Marris uses perspective from well-respected scientists such as Hobbs to strengthen her argument for Designer Ecosystems.  Marris then goes on to praise the work of Ilkka Hanski, a researcher from Finland who has quite a unique garden.

Designer Ecosystems, what are they?  In many ways they sound like what they are.  They are habitats, wildlife, flora that are designed through effort.  Hobbs says that many ecologists will like a certain species if it is native to the land.  “Depending on whether you say it was native or not native they like it or don’t like it,”

(Location 2452).  To him it was a game.  Too many ecologists rely on baselines for “pristine wilderness.”  The idea behind designer ecosystems can be described in these lines when Hobbs says, “You are not going to get the previous ecosystem back, but you can still aim for something that is valuable,”

(Location 2480).  Hobbs is talking about an area where the soil was so salted that the eucalyptus tree was no longer able to survive.  The possibilities of what to do with this soil now seem endless.  Hobbs flirted with the idea of turning the land into a prairie that could feed the native birds and also serve as biofuel.  Such transformations, though not 100% pristine could serve a great compromise to natural and human needs.  These efforts of designer ecosystems are one way conservation is happening everywhere.

Chapter 9 in Rambunctious Garden talks about what conservationists and ecologists are working on globally.  In Seattle, the Duwamish River has become part of the ‘industrial waterway.’  Surprisingly enough, there are signs of life in these toxic waters, although there appear warning signs to not eat any fish caught in the river. Activists are trying to improve rules and regulations to get more conservation value.  One way is with private landowners.  If a landowner chooses to not develop his land, he will be the beneficiary of a large tax break.

Other strategies for conservation are prevalent throughout Europe.  One such is agri-environment.  This strategy involves reworking farms so they are suited for greater species.  Europeans are protecting farmland birds by rolling back on monoculture and herbicides.  They are using the land more efficiently.  Marris goes on to say that this rural ecology shift is great but as of 2009, more than half of the Earth’s population lives in cities.  That is why we are now moving into a period of Urban Ecology.  Now, wastelands will be used for plants and it all starts at the top.  Big companies will have to be innovators, starting with green roofs and utilizing unused space for planting more diverse, thriving species.  We need to see nature as the background of our own lives.

 

Chap 6 & 7, A Novel Invasive Species Dominated Ecosystem

What are ecologists supposed to do about invasive species?  In Chapter 6 of Rambunctious Garden, Emma Marris discusses the possibilities.  In Chapter 7, the concept of a Novel Ecosystem is discussed and there have been some arguments as to what that is.  We will see the problems and potential solutions of both invasive species and novel ecosystems.

Invasive species are just what they sound like, an unwanted plant or animal that is accidentally introduced to an ecosystem, and thrives.  The species overtakes the native population and many times destroys a beloved species.  An example of this would be feral cats in New Zealand.  Marris points out that the cats wiped out the native wren.  Another example would be the brown tree snake in Guam.  The snakes also killed birds.  These birds were pollinators that distributed fruit tree seeds.  What solutions do scientists have in mind?

One solution is physically removing invasive species by using strike teams.  Unfortunately, strike teams are very ineffective.  Within a few years the “exterminated” species becomes invasive again.  Top ecologists like Shahid Naeem of Columbia University,  “would love to get rid of every invasive species on the planet and put all native species back in their place.”  This agrees with the idea of a novel ecosystem.  An ecologist like Naeem would think that a novel ecosystem is one dominated by native species.

Ecologist Mascaro holds an alternative view of novel ecosystems.  He believes that an ecosystem shared in dominance by native and exotic species is what makes it thrive.  He looks at the services being provided by the exotics such as filtering water, controlling erosion, and building soil.  A native ecosystem does not necessarily have these things.  Mascaro describes his favorite ecosystem, the mango forest.  The forest is filled with life in every crevice.  There is strawberry guava (considered invasive), rose apples, the Queensland maple, and candlenut.  All of these invasive species are living together in harmony.  Many traditional ecologists will disregard this area because it is filled with invasive species.  They are living in a quite healthy ecosystem, though.

It is things like this that make me question an ecologist’s agenda.  In politics, there are liberals and conservatives.  I did not know that was the case in ecology.  There are a new class of liberals, like Mascaro, who are trying to stick up for these invasive species by saying that ultimately they are good for the ecosystem.  Other ecologists like Naeem are saying that the old baseline method that ecologists have relied on for decades is the way to go.  It is just a political debate within science in my opinion.

What is an invasive species? Is it merely something that was not there when the Europeans arrived?  But what if that species is actually good for the environment, like the strawberry guava for the Hawaiians.  Marris states that invasive species are only really overpopulated for the initial few years, the environment controls them eventually, like the zebra mussel, which became food for the ducks on Lake Erie.  Maybe a novel ecosystem could have invasive species, but it remains to be seen if ecologists can live with that.

The High Line: A Natural Experience in NYC

One of the most visited nature sites in New York City is the High Line.   The attraction spans from 14th Street to 34th Street along 10th Avenue.  It was my second visit to the Highline and the first time that I actually saw the plants and paid attention to pollinators.  People of all different races, genders, and styles visit the High Line to appreciate the natural elements, plants, and spectacular views of Chelsea.   

Upon climbing the stairs of the 23rd Street entrance of the High Line I was surrounded by a diverse people.  There were young men and women holding hands, young children begging for ice cream, old ladies telling them to be quiet.  Business people looking for a break in the day, a saxophone player accompanied by a vocalist, jamming out; these were the people of the High Line.  What united them?  Was it nature?  Was it the sounds of the birds?  What was it?

Personally, I think people go to the High Line to relax.  It is very peaceful up there.  Especially considering that 20 feet below you sits the heart of Chelsea (on 23rd Street).  Nature, on the West Side of Manhattan, seems out of place up there, but highly appreciated.   What types of plants were there?  I am no botanist, so my best summary is: a rainbow of all the colors you could see, but one color on one plant; some had thorns; some were dying; some were thriving; some had birds all over them; some had insects and bees pollinating like wildfire; it was different.

Pollination.  Many overlook the process.  It truly is an art form, and those who are good at it are relentless.  The bees will stop at nothing, not even 40 mph winds.  The birds only seemed to be around one plant, the fruitful looking purple one.  The small orange insects that I have never seen are nested along a brown leafed plant.  The day was windy, overcast, and overcrowded with New Yorkers, but these animals were in their own domain.  Shielded by a fine green line, they were in their own habitat, created by humans, untouched by humans since.  You get the feeling that some plants are more loved than others: some appear more vivacious.  That could be a result of something that Slater points out.

He says due to shallow soil profile, soil depth ranges from 1 centimeter to 70 centimeters (over 2 feet).  Perhaps this is a reason why some plants appear brown on the last day of summer and others are thriving with beautiful colors.  Slater brings up an interesting point saying that the High Line has the highest species per area with respect to 4 other major coastal sites including Ellis Island and Liberty Island.  It is easy to see why this may be the case.  The High Line is only 20 blocks long, and just over 20 feet wide.  The total number of species on the High Line is 163, which is third following Ellis Island and Bayswater Park.

Is the High Line a Rambunctious Garden?  It would appear so.  The High Line is a natural space strategically created by Kelco.  It is built to serve nature and humans.  There are practical and artful uses for this great space.  Ultimately, this is now nature, that is created, should be enjoyed by the masses.

Manhattan: Too Drunk to Drive

Overall, the graph presented above shows that a majority of New Yorkers walk and ride their bikes as transportation throughout the boroughs.  The borough with the highest concentration, as expected, is Manhattan, with over ¾ of the population walking or biking.

This graph, overall, depicts a decline in walking and biking in New York City in general.  I separated the years, and used a common variable of poverty level, which seems to have no major effect on walking and biking in the city.  Roughly, the percent of any individual who either walks or bikes is 60-70%.  Numbers have decreased though, from 2007 to 2010.

 This scatterplot states the obvious.  The lower percentage of adults who are overweight or obese, the higher percentage of people who walk or ride their bikes is.  There is a moderately negative correlation between obesity in adults and the percentage of people who ride their bikes or walk.

This graph shows the percentage of adults and youths (high school) who engage in smoking.  In adults, smoking has seen a gradual decrease from 20% to 15% from 2003 to 2010.  From 2003 to 2007 high school students have seen a decline from 15% to 8% and since then it has plateaued.

This useful tool lets us see the heavy drinkers in NY.  Interestingly enough, if you are located near the shore, you are more likely to be wasted.  Manhattan is the borough with the highest density of heavy drinkers.  Queens or Staten Island is the most sober borough.

Lending a Helping Hand to Trees in Need

Climate change is a real threat to current plant and animal species worldwide. Emma Marris emphasizes this in her book, Rambunctious Garden. An increase in global temperature worldwide forces animals to move closer to the poles to seek cooler temperatures.  Plants, on the other hand, have a much tougher task migrating to more desirable regions.  This is why the practice of “assisted migration” came about.  Essentially, conservationists transport these plants safely to newer climates in hopes that the population will survive.  The primary reason for these efforts is to save species.  However, scientists warn that moving these species to new ecosystems could disrupt their balance of nutrients, which would do more harm than good.  By the same token, a species could take so well to the environment that it could reproduce exponentially and become an invasive species.

Many scientists feel that assisted migration has the potential to be very useful for saving species.  Big name scientists such as Camille Parmesan and Hugh Possingham have cited various benefits.  If a specific population is highly endangered and easily able to transport then it should be done.  This, however, seems obvious.  The real question that many scientists have is, “How would assisted migration affect the current ecosystem in place?”  This is the million-dollar question that cannot simply be answered with proxies.  In order to really see the effects there has to be a series of trials.  One such trial was in North Carolina where the torreya, a tree native to Florida, was migrated.  Thirty-one seedlings were planted and the funding came from two private citizens.  The plant is not expected to be invasive.  Other scientists like Hellman worry about the safety of these transported species.  She says maybe the other species that made it thrive, like beetles or microbes, would be absent from the new location therefore harming the survival rate of the migrated species.  No one will ever transport those tiny critters.

Personally I do think assisted migration is a useful tool, especially if humans want to save plants that are beneficial in commercial and environmental ways.  The torreya was often chopped down as a Christmas tree.  Many other plants are used for ecological development of areas.  Americans today are more exposed to threats of global warming.  One way to help out species that are dying is to manually place them in more suitable regions.

The Puth and Burns study shows how ecological transformations in the NY Metropolitan area are impacting species richness and diversity.  The study focuses heavily on urban areas because by the year 2030, 60% of earth’s population will be residing in cities.  In 17 of 26 studies produced, the species richness was decreasing from 1984-2000.  The highest rate of decrease has been in mixed ecosystems.  This is a concern that the local governments will have to make.  How will they divide the land so that humans, plants and animals can live together?

Overall, assisted migration presents an answer to both arguments.  I think scientists should focus more on saving species, but this comes with many caveats.

Rewilding in the Modern Era

What will they think of next?  “Rewilding,” as discussed in Emma Marris’ Rambunctious Garden describes the strategy of reintroducing large animals to a geographic area, which they once dominated.  This practice is designed to restore nature to how it was even before the arrival of the Europeans.  There are various challenges that this project faces; many have doubted its effectiveness and have called the project unethical.

What prompts scientists to reintroduce wolves to Yellowstone? Or, better yet, cheetahs and other exotics into the US?  This “rewilding,” coined by Dave Foreman of Earth First!, has been in practice since the mid 1990s and brings back “top of the food chain” predators to their native environment.  The logic behind it is simple, because these large predators are not around, medium predators like raccoons and snakes eliminate smaller animals such as songbirds.  The end result is fewer species all together.  The problem with many ecologists who wanted to return America to pre-Columbian times was that many species are now extinct.  They thought a proxy, or replacement with similar characteristics, would suffice.  In 2004, 13 well respected scientists and conservationists discussed the idea of reintroducing these proxies of extinct megafauna to the US.  A problem with these proxies is that in many cases they are not the native species and can play a different role in the ecology of the area.

The ethical dilemma with this practice begs the question of should humans effectively alter these environments?  Oostvaardersplassen in the Netherlands is a perfect example of humans altering the environment to a natural state where there is no human involvement at all, other than killing weak animals who have wandered away from their counterparts.  The cattle “mows” the grasslands and therefore the forests that once inhabited the entire continent will be contained.  Vera’s project has seen great success because he has lured predators such as vultures and eagles back to their natural environment.  Vera, has let animals do the work instead of paying humans.  His project includes wild Konik ponies, red deer, and foxes.  Much of Oostvaardersplassen is quite the opposite of the preserved Białowieża.  Białowieża was always in royal control and served as a hunting ground for the elite.  It is heavily forested and in many ways considered as the pristine wilderness.

If Vera would have his way, humans would not interact with “natural” environments.  But this is scientifically impossible because humans have always interacted in their environments since their existence.  There is not one square mile on the inhabited earth that has not been touched by human hands.  It is impossible to go back to the days where humans never existed and when large predators roamed wild.  In Texas, there is a ranch where dozens of wild species are thriving.  There is much controversy behind this establishment because people can pay $10,000 to hunt an exotic breed there, but that is what conservationists, like Vera, are trying to avoid.  They want animals to exist because they should.

From AUS to USA, The Hunt for Pristine Wilderness Continues

Rambunctious Garden, written by Emma Marris, opens up with tales of conservation methods in Australia.  In Chapter 2, Marris goes on to describe the Yellowstone Model.  Marris is quick to assert her point that using baselines for conservation may not be the best, or even damaging, to the ecosystem.  The author defines a baseline as a point in time at which conservationists aim to restore the land to “pristine wilderness.”  It is most often pre-European.  Instead, she says that ecosystems are constantly changing, and human efforts to preserve these lands should reflect that, instead of restoring them to an anachronistic time.

In Australia, conservationists have attempted to restore lands to pre-European times.  The Australian Wildlife Conservancy, in 2009, tried to restore a 250 square mile piece of land, Scotia Sanctuary, to pre-European times. This project was arduous and expensive.  The Australian plan faired well because it required killing feral animals like goats, foxes, cats, and rabbits.  The hunters shot the goats, trapped the foxes and cats, and poisoned carrots to rid the rabbits.  That is quite an extreme example (that PETA would dislike), but it worked in the sense that the “little furries” were now under no threat.  Native species thrived.    Therefore, Scotia Sanctuary proved that achieving a historical baseline was possible, under intense management.  But what does “management” entail?  Is this land no longer wild if it is “managed?” Maybe.  Is this land no longer “pristine wilderness” because of human intervention?  Not quite.  Let’s look at America’s answer to the quest for pristine wilderness.

The Yellowstone Model serves as a guide to the world of what conservation is today: setting aside wilderness areas and banning human use apart from tourism.  Never before had a society voluntarily restrained itself using natural resources in deference to higher uses of nature such as pure enjoyment (Marris).  Now 13% of the Earth’s lands are protected areas.  Is this necessarily right though?  In 1877, Native Americans were forcibly removed from their lands. This is very ironic because it was the care of the Native Americans that first interested the conservationists in the land.  Needless to say, the ecosystem suffered without its caretakers.  I think Marris will use Yellowstone of what the face of conservation used to be.  Sure, having this great area of “untouched” space is great but is it really productive?  Does it really suit to the needs of the land and the people?  She compares it a bit to the European model of aiding human use and avoiding extinction.  Americans perfected this model of nothingness, leaving the land as it is, and exported that to the world.  Both ideas are being debated here.

Emma Marris presents excellent cases so far.  Australia’s model of returning to the baseline proved successful.  Wyoming’s Yellowstone has also seen success.  Both attempt to move their respected lands into “prestine wilderness,” Yellowstone with no activity whatsoever, and Scotia Sanctuary with human intervention.  I am inclined to think that Marris believes in the latter.

 

The Anthropocene and Urban Ecology

When looking at the Anthropocene there are many factors to consider.  Are we humans ultimately responsible for conserving our planet for the next era of rulers?  That question is essentially what Vitousek and Kareiva try to answer.  Vitousek approaches the problem with vigor and is quick to point out all of the flaws of human intervention in the ecosystems of the world.  Kareiva, in turn, addresses the problems conservationists have in dealing with the harms that come with human technological advancement.

 

According to Vitousek, approximately 1/3 to ½ of the earth has been transformed by humans.  What have been the results of this involvement? Vitsousek cites examples of deforestation, hunting and fishing.  These are dangerous activities humans do that directly effect their respective ecosystems.  Vitousek goes on to state that many of these activities cause “irreversible losses of biological diversity.”  The examples of humans burning through forests for precious trees for a variety of needs from housing to paper paints the picture that we are effectively destroying the ecosystem.  We humans, are responsible for the close to 20% increase of CO2 emissions caused by land transformation.  A consequence of this has been a global climate change.  An astounding statistic mentioned by Vitousek, Marine Fisheries discard 27 million tons of nontarget animals, essentially altering that habitat and ecosystem.  By taking these sea creatures out of the environment, both animals that are prey and predator will have population surges and declines, respectively.  The effect on humans is not recorded.

 

Overall Vitousek acknowledges that humans have touched every ecosystem and have transformed or destroyed as many as half of them.  Fossil fuel combustion adds about 5.5 billion metric tons of CO2 emissions to the environment annually.  Synthetic organic chemicals such as Polychlorinated biphenyls have decimated many large bird populations like the Eagle and Falcon.  Vitousek cites many of the problems and fallacies with human intervention and is rarely vocal about any conservation efforts.  Kareiva is much more moderate in his approach.

 

On a much different note, Kareiva, starts his article about how 13% of the world is actually protected.  What is surprising is that most of these lands are uninhabited by humans.  Conservationists have worked to create parks  and “protect” wilderness but now the question facing them is how to address landscapes and urban ecosystems.  What is an urban ecosystem?  Well, it takes all the work that conservationists have been doing away from humans and puts it in the direct path of  the mass population.  Urban ecology helps to address how government and organizations deal with pollution of air and water.  This is a much more practical solution to solving the problem at hand.

Kareiva concludes with how resilient nature is.  There is a new vision for conservation and organizations should team up with corporations to try to address this issue together.  The end all goal should be to enhance ecosystems so they benefit the widest array of people and serve them effectively.
