Seminar at UW: The River Wolf and The Blue Pearl

I attended a seminar on December 2, 2010, put on by Olaf Jensen about the conservation of salmonids in Mongolia. The speaker, Olaf Jensen, graduated from the University of Wisconsin with a degree in Fisheries Sciences. A project was started while he was a graduate student at the University of Wisconsin that was set up to protect a species of fish, the taimen, in Mongolia. The project was and is funded by The World Bank, and it is set in the Eg-Uur Watershed in Mongolia. It is a non-governmental organization set up to develop recreational fishing in Mongolia as ecotourism, to fund aquatic ecology and fisheries research, to research conservation in the area, and to fund conservation law enforcement. Dr. Jensen studied whether recreational fishing is compatible with conservation and also evaluated taimen movements with respect to the river ecosystem. He found that catch and relsease fishing would have barely any impact upon the taimen population but that commercial fishing would have a high negative impact upon the taimen population.

His studies have implications for indigenous Mongolians because it shows that commercial fishing levels would decimate the population of taimen in the area and bring few economic benefits to the people actually living in the region. His studies will be used to protect the people native to that region of Mongolia, and the taimen will be protected so the people of Mongolia can continue to fish in a sustainable fashion.

An Amazing and Inspiring Collaborative Fishery on the Columbia River between First Nations, a Public Utility, and Bonneville Power Administration

Recently, an amazing display of partnership between First Nations, the Washington State government, and private industry has resulted in an amazing accomplishment for the furthering of salmon populations. Since 1955, the Chief Joseph Dam on the upper Columbia River has completely blocked salmon migration. The many harmful effects of dams including reducing dissolved oxygen gases, reducing sediment flow, and blocking salmon transport have greatly affected the way salmon travel this part of the Columbia River for many years- resulting in negative impacts on the salmon population. Fortunately, the First Nation called “The Confederated Tribes of the Colville Reservation,” Grant County Public Utilities District, and Bonneville Power Administration, are working together to establish a salmon hatchery on the upper Columbia.

Salmon have always been an integral part of the First Nations’ for reasons of tradition, culture, and sustenance. It is important to practice sustainable salmon management so that First Nations’ can enjoy the salmon fishing rights they were granted through treaties with European settlers in the late 1700’s to 1800’s. Salmon protection is also important to numerous stakeholders, including the U.S. government, fisherman, non-governmental organizations, utility companies, artists, recreationists, and many more. For this reason, a new salmon hatchery on the Columbia will benefit many people for many years.

Grant Public Utilities District will fund approximately 1/5 of the $40 million hatchery, with the Bonneville Power Administration financing most of the rest of the project. The “Confederated Tribes of the Colville Reservation” will manage and operate the hatchery. This hatchery will be a wonderful project, raising 1.9 million summer Chinook and 900,000 spring Chinook every year. I think it is wonderful that 3 organizations with different interests on many topics could come together and establish a very worthwhile project for the region, the fishing industry, and the First Nations of the Northwest.

Surprising Research on Utility Companies that are Implementing Programs to Protect Fish (Salmon) on the Columbia River

Until now, I thought that all utility companies supported power generation regardless of its effect on salmon. However, in my research I have found a utility that is concerned about salmon and is currently implementing many programs to preserve and protect salmon so they can thrive in the same location humans do. The Grant County Public Utility District (PUD), located in Ephrata (Eastern) Washington, is making great strides to dissolve the nature-culture dichotomy by showing that humans have a responsibility to not only remain involved in the environment; they have a responsibility to protect it. This public utility is doing this by creating programs to protect salmon on the Columbia River.

In my research, I have been able to divide Grant County PUD projects into four main categories and several subcategories:

1. Projects that physically improve the structure and quality of streams and dams
• Funds habitat projects that benefit fish stocks on the Columbia
• Remodels stream culverts which are inefficient and harm fish
• Operates two fish ladders at each dam, to create a safe way for fish to travel upstream to spawn.
• Operates sluiceways (also known as spillways). Sluiceways allow for runoff of excess water, as well as another way for steelhead and Chinook salmon to pass through. Two sluiceways it maintains are at the Priest Rapids and Wanapum Dams.
• Runs four stations in the Priest Rapids Project Area to continually test the water quality and ensure it remains optimal for fish survival.

2. Projects that seek to maintain and increase the number of fish that live in the river
• Removes fish barriers as much as possible
• Conducts extensive research into fisheries to make sure correct and sustainable methods are being used
• Initiates a myriad of programs to protect and preserve fish, especially at their most delicate stages of life
• Currently co-funding a hatchery

3. Projects that monitor and record changes in fish populations for future reference
• Creates and assembles useful images of the upper Columbia
• Uses Passive Integrator Transponder (PIT)-tag detection equipment at fish ladders, specifically at Priest Rapids Dam, to make sure the fish ladders are operating correctly and survival rates of migrating fish are not decreasing.
• Counts the number of fish migrating through the fish ladders at the Priest Rapids and Wanapum dams. This critically important research helps Grant County PUD, Washington State, and other interest groups by providing knowledge about Columbia River salmon populations and how to better manage the river in the future.

4. Other projects
• Purchases land so it can be set aside for conservation
• Serves on the The Priest Rapids Coordinating Committee. This Committee has established objectives to increase fish populations back to sustainable harvest levels in the middle Columbia. It also brainstorms and initiates projects to combat fish mortality from pollution, overharvesting, and other causes.

My research both surprised and pleased me, because I previously thought utility companies were too invested in power generation to care about maintaining sustainable river environments for fish. But I was very wrong- Grant County Public Utility District has done just the opposite and made salmon conservation a priority. Despite all the environmental destruction going on, this one fact gives me hope that some citizens who do care about making a profit also care about preserving the environment.

Glacial Melt - Social Impact and Adaptations

In our blog's last post, Rebecca looked at some of the physical and environmental actions and consequences of the worldwide trend of melting glacial pack. Her piece intrigued me, and it reminded me of some of Dr. Pena's lectures regarding the influence of the glacier at his acequia farming institute. He tells of how the glacier near San Luis (which has an aviary-themed name I am presently forgetting) is a device for the famers to judge their potential growing seasons, and is also the source of their irrigation systems. I was curious about other impacts of glaciers on the livelihoods of people across the world.

I looked up these two articles:
http://insciences.org/article.php?article_id=9698
http://www.reuters.com/article/idUS105071633920101116

Glaciers have huge implications! They provide water to the some of the most important rivers in the world - the Ganges, the Indus, The Yellow, not only do millions rely on these rivers today, but they have arguably the most historic significance of any rivers - literally the cradles of civilization.

The effect of climate change on glaciers will directly and negatively influence the lives of the people that have depended on them for centuries. People will could see (and have seen) their drinking water flood up and destroy their livelihoods, know as Glacial Lake Outburst Floods. Tragically, this is noted in some of the most impoverished and vulnerable places in the world. One of the tenants of Environmental Justice is to rectify the unfair disproportion of degradation on the underrepresented people of the world. The ethically correct choice is for nations to investigate climate change as a real and dangerous force. The climate change argument is highly politicized, but is the responsibility of the empowered to take on the challenge of climate change immediately.

Melting Ice - Sea Level Rise

I read an article in the New York Times recently that really caught my eye. I think initially I was interested because it had to do with glaciers and I have spent a lot of time studying glaciology, but it also really made me think about what the future has to hold.
It seems as though the ice of the world is melting at an alarmingly rapid rate. Originally scientists believed over the next century the Greenland and Antarctic ice sheet melting would raise the sea level about seven inches, but this is no longer the case. It appears that with current rates of melting, the sea level could rise by as much as 3 feet by 2100. This would have a detrimental effect to coastal areas. Some extremely influential cities that would be affected include: London, Bangkok, Venice, Cairo, and Shanghai.
Although climate scientists understand there is a strong chance they could be wrong about the changes over the next century, they are still urging government to take action on heat-trapping gasses. When the Greenland Ice Sheet is fully melted, it will raise the sea level 7.5 meters (which is equal to almost 300 inches), and that is something to worry about! Although this seems almost impossible to comprehend, the Antarctic Ice Sheet is almost 10 times bigger.
What many people don’t understand is how small changes in sea level can create huge problems on land. With only an inch or two change, the sea can cause massive amounts of land erosion which can affect many homes. The question isn’t whether or not climate change is going to negatively affect human life, but how fast can humans adapt to the changes?
The most recent estimates by climate scientists predict the sea level to rise about 3 feet by 2100.
Since the industrial revolution, the amounts of greenhouse gasses that have entered the atmosphere have been off the charts. Even though people have lived for at least thousands of years without these threats of warming, the threat is now moving at an exponentially rapid pace. People absolutely must see the urgency in the threats of climate change including the way in which it will directly effect them in the coming decades.

Mercury Contamination in Amazon Region

A study was done in Santarém, Pará, Brazil about mercury contamination in fish. In this region of the Amazon lots of mercury is released into the atmosphere. It is generally accepted that the mercury comes from the goldmining activity in the area. The amount of mercury in the region is predicted to be as much as 70 to 130 tons per year based on the gold production from this area. Organic methyl mercury is the most toxic and is accumulated mostly by the large predator fish. This town this study was done in, is not that close to mining activity. However there is other commercialization there. The main questions that were trying to be answered were: What is the difference in contamination in the different species of fish? And what is the correlation between weight of fish and mercury concentration?
Santarém is located in Pará State, which as a whole has the most goldmining sits in the Amazon region. Furthermore, there are six rivers surrounding Santarém. Fishing is one of the most important economic activities in this area so whether or not the fish are safe for human consumption is very important. The fish that were used came from the local markets. The locality of the fish was possible to be determined by asking the specific farmers where they came from. There were 109 fish in total, both carnivorous and non carnivorous.
After the fish were tested, it was discovered that carnivorous species of fish have about five times more mercury in them than both herbivores and omnivores. One species in particular, Tucunaré, tested 2% above the legal limit for safe eating. The highest level in this species was 700 ng.g-1 of methyl mercury. In total, about 1% of fish had mercury levels above 500 ng.g-1 .
What the people in this region need to realize is consuming these fish on a daily basis may have a detrimental effect to their health. Particularly considering that about 90% of the mercury in these fish is toxic methyl mercury. Now that the high levels of mercury have been discovered, there will be more attention paid to the bioaccumulation process of mercury in the fish. It is not easy to avoid just the species of fish with high mercury levels because the area has so much biodiversity. Also, due to the amount that fish effect the Amazonian culture, from food to economy, limiting how much fish they consume is hardly an option. The best way to deal with this problem is by involving environmental politics. (de Souza et. al)

This just shows another way that anthropogenic effects are harming the environment. This is a particularly bad case since there are very few practical uses for gold in comparison to how much it is used solely for jewelry. The gold miners must be held accountable for what they are doing to the surrounding people. I would imagine that these miners are also eating the fish with mercury in them since they probably live somewhat close to where they work, and that makes even less sense.

The Columbia Riverkeeper and Salmon



Columbia Riverkeeper is a non-governmental organization dedicated to “…restore and protect the water quality of the Columbia River and all life connected to it, from the headwaters to the Pacific Ocean”.  They deal with issues pertaining to the health of the Columbia River system.  They use methods such as grassroots community organizing, the law, and community outreach to help reach goals.  These goals are diverse, but all of them relate to the health of the river and the communities that surround and utilize the river system.
                  Columbia Riverkeeper has multiple programs to accomplish their goals.  They test the water in the Columbia River in key salmon habitats to make sure the water is healthy for the fish; they do this by sending out volunteers, proving that communities around the river care a lot about the health of the river and the wildlife in it.  They also train volunteers to rehabilitate sections of the Columbia River via the Adopt-A-River program.  Besides the volunteer work Columbia Riverkeeper's members do, they use laws to ensure the river is kept safe from illegal developments, and they also lobby the government to strengthen existing water laws to keep our river safe in the future.
                  One key project Columbia Riverkeeper is working on currently is the prevention of shipping sites being built in the Columbia River estuary.  There are four sites that have already been proposed.  The main purpose of these sites is to ship coal from the United States to China, which is extremely problematic for the entire river ecosystem because of the increased traffic, pollution, and construction on the sensitive estuary.  Shipping sites will harm salmon because pollution and boat traffic will increase in the area where the river meets the ocean, which is a critical point in the reproduction cycle of salmon.
