Excess Nutrients increase Ocean Acidification

Nutrient loading and its effects on the health of the Salish Sea was a topic covered from a variety of perspectives at the recent Salish Sea Ecosystem Conference in Vancouver, BC.  The most common threat from elevated nutrients is hypoxia, or dangerously low levels of dissolved oxygen as is found at times in Hood Canal.  But another threat is emerging and was discussed at the conference.  Excess nitrogen can add to the decrease in Salish Sea pH we are experiencing from climate change and which is threatening the shellfish industry.

Excess nitrogen in the marine environment fuels algae growth.  When the algae dies and is decomposed by microbial action, CO2 is produced–the more algae, the more CO2.  This CO2 from microbial respiration has the same effect as atmospheric CO2–it lowers pH.  Thus CO2 in marine waters has two sources–the atmosphere and microbial respiration.   And, as anthropogenic sources of nutrients increase algae growth, acidification and all its damaging consequences are accelerating.

What is most alarming is that the combination of the two sources of CO2  (atmosphere and respiration) seems to have more than an additive effect–there is some sort of synergy that lowers pH beyond what would be expected from the sum of the predictions for each of the two sources when modeled alone.  In the context of the relatively limited water circulation found in the Salish Sea and especially in South Sound where nutrients tend to linger for long periods of time, this emerging science increases the urgency to control or treat all sources of excess nutrients to help compensate for the effects of climate change.

2011 Salish Sea Ecosystem Conference

Last week I had the pleasure of attending the 2011 Salish Sea Ecosystem Conference  in beautiful Vancouver, BC with four of my fellow Squaxin NR colleagues.

Throughout the three days I sat in on a number of breakout sessions and reviewed scientific posters that ranged in topics covering Estuary Science, Marine Survival of Salmon, Marine Mammals, and Traditional Foods of the Salish Sea to name a few.  The conference was what I would call a “Salish Sea Scientist Convention,”  a group of scientist striving for a common goal….a healthy and plentiful Salish Sea.

As I reflect back on the sessions I attended at the conference,  most were very interesting, but one in particular about Snow Geese and Bullrush was one of my favorites.

The presentation, “Why are estuarine marshes in the Salish Sea disappearing and what must be done to fix the problem?” from Sean Boyd of the Science & Technology Branch, Environment Canada.  Mr. Boyd shared his studies of how Snow Geese have contributed to the disappearing marshes in Canada. Recent years Snow Geese populations in the Fraser Delta have significantly increased do to favorable breeding grounds and the decline of harvest.    The recent increased population of Snow Geese is decreasing Bullrush density .  Snow Geese eat Bullrush rhizomes and apparently consuming them at the same rate as they are being produced.  With the decline in Bullrush, Mr Boyd explained that these areas were reverting to mudflats of which could have serious impacts on food web.

Mr. Boyd’s recommendations to resolve the decline of Bullrush and increased populations of Snow geese are two fold:  Reduce the  Snow Geese to a manageable population through harvest and apply nitrogen  fertilizer to Bullrush marshes to increase rhizome density.

The 2011 Salish Sea Ecosystem Conference was very informative and I am thankful to attend.

Squaxin Island Tribe, Capitol Land Trust, LOTT work together to protect habitat

The Squaxin Island Tribe and the Capitol Land Trust are hoping to purchase and protect an important piece of forestland between Henderson and Budd inlets as part of a joint effort to restore and protect habitat between the two south Sound inlets.

“In total, we would protect almost 60 acres,” said John Konovsky, resource protection manager for the Squaxin Island Tribe. “Most importantly, the property contains more than 10 acres of a vital 70 acre wetland.”

The purchase will largely be funded by a grant the tribe received from the U.S. Environmental Protection Agency. The balance of the funding would come the LOTT Clean Water Alliance, the local wastewater utility.

Protecting the forestland and shoreline between Budd and Henderson inlets is a high priority for both the tribe and the land trust because the area is relatively undeveloped. “Since this area is so close to an expanding urban center, it’s important to protect as much as possible before it is destroyed by development,” Konovsky said.

In addition to land purchases, the partnership could also lead to habitat restoration projects, such as culvert removals.

The unique partnership between the tribe and the land trust is key. “The tribe has expertise with research and directly managing natural resources, while the land trust has worked with hundreds of landowners to protect important areas” Konvosky said. “The tribe and the trust have a long-time working relationship.”

The Squaxin Island Tribe has been studying deep South Sound for decades and recently completed a habitat assessment of Budd Inlet, where the tribe has been monitoring juvenile salmon populations.

“Protecting and restoring habitat is the single most important thing we can do to restore salmon and to bring Puget Sound back to health,” said Andy Whitener, natural resources director for the tribe. “Restoring salmon and repairing Puget Sound is a massive undertaking. It’s great that we have been able to find partners in the community to help us out.”

“Protecting our treaty-reserved right to harvest depends on a healthy ecosystem, we appreciate the support we get from our neighbors,” Whitener said.

Come support the tribe’s fight to protect fish!

Update:  Judge Paula Casey ruled in favor of the Squaxin Island Tribe to protect Johns Creek!

Fish runs in Johns Creek, near Shelton, have been shrinking for years.  Wells are stealing water that should flow into Johns Creek.  Ecology has refused to stop new wells until it knows where wells can be safely drilled.

So, the Tribe sued Ecology and Mason County.  In March 2011, Judge Paula Casey issued a great opinion!   She said that Ecology made a big mistake in denying the Tribe’s request.

Come again and watch round 2.   This time, the battle is over what Ecology must do when the case is returned to it for corrective action.  Ecology wants a free pass, but the Tribe wants more — real benefits for fish.  On Friday morning, September 2, the Tribe’s Legal Department will argue the Tribe’s case to Judge Paula Casey in Olympia.

When:  Friday, September 2, 2011, at 9:00 a.m.  It may happen later in the morning, but we will not know until the day before…

Where: Thurston County Superior Court, 2000 Lakeridge Dr. SW, Olympia, WA 98502.  Go to Building #2, Room # 257.

Conservation Futures funds should be used for conservation, not urban parks

We have learned that the Thurston County Commission intends to support using Thurston Conservation Futures money to support “preserving” land for an urban park in downtown Olympia. This appears to fail the test of the intended use for this funding source and does nothing for conservation. If this is how money will be doled out, then the Tribe has been duped into supporting this funding program.

The Conservation Futures Program is established by State law to acquire interests or rights in real property for the preservation of open spaces. Funds are acquired through a property tax levy, in Thurston County 3.85 cents per thousand dollars of assessed valuation, and are used to purchase the land or the rights to future development of the land.

Conservation Futures is a land preservation program that protects, preserves, maintains, improves, restores, and limits the future use of threatened areas of open space, timberlands, wetlands, habitat areas, culturally significant sites, and agricultural farmlands. It was foreseen as a tool to help offset the impacts of urban sprawl by acquiring properties outside the urban area and in recognition of the Growth Management Act principles for increasing density within the urban growth boundaries.

The Legislature found that Conservation Futures are a useful tool for counties to preserve land of public interest for future generations and are encouraged to use some conservation futures as one tool for salmon preservation purposes.  It is one source of funding that many partnerships have looked to help fund acquisition of land for habitat purposes. Clearly, if money is used to acquire already developed urban land for conversion to parks, there is less money available for acquiring land and habitat and easing the tension from landowners who feel their land is being taken by regulatory fiat without compensation. Projects like protection of the valuable pocket estuary at Gull Harbor or the acquisition of Woodland Creek riparian corridor will fall by the way side as funding is redirected to questionable projects.

But don’t take my word for it. Check out the funding criteria developed for the newly implemented project selection process. Does the project preserve unique or critical habitat? Does the project preserve unique natural features and or natural resources? Does it preserve critical or sensitive lands like wetlands? How did an urban park ever acquire enough ranking points to be considered a priority?

Conservation Futures is a valuable tool for conserving fish habitat and protecting open space in a county under extreme pressures from population growth. It would be a serious waste of resources and a kick in the gut of open space advocates to misuse this funding source to appease the advocates for expanding the State Capitol Campus.

The myth of a watershed solution to cleaning up Capitol Lake

Proponents of keeping Capitol Lake say that if we only cleaned up the entire Deschutes River watershed, water quality problems in the dammed estuary would go away.

From the Save Capitol Lake website:

Broaden focus to watershed for improved water quality: The CLIPA findings support more effective management of the upper Deschutes Watershed to address water quality issues including: dissolved oxygen, temperature, nutrient loading, sediment control, and removal of point discharges of other contaminants.

Actually, water quality problems such as dissolved oxygen, temperature, nutrients and sediment are inherent to the lake itself and aren’t caused by an up-river problem.

John Konovsky, environmental program manager for the Squaxin Island Tribe recently gave a presentation on how little watershed actions can do for the health of Capitol Lake:

We totally agree with CLIPA that a watershed approach is essential the maximum water quality benefit to the whole system. Where we kind of disagree is that a watershed approach is not sufficient to clean up the lake. The lake has some inherent problems.

Konovsky’s main points:

  • Capitol Lake is too shallow and stagnant to control temperature.
  • 75 percent of the fine sediment coming down to the lake is natural.
  • The lake would need to be 300 feet deep to control algae blooms.

DNR partners with Department of Ecology, Squaxin Tribe and South Sound Salmon Enhancement group to restore Puget Sound

From the DNR blog Ear to the Ground: http://washingtondnr.wordpress.com/

DNR and its partners have removed 3,150 square feet of overwater docking structure — the last remaining overwater structure on Squaxin Island. Removed were 48 creosote treated wood pilings and 84.6 tons of creosote treated wood.

The dock, which provided tribal members access to an old long house on the island, is the second phase of creosote removal for this project. A 400-foot rock bulkhead along the Squaxin Island shoreline, adjacent to the dock, was also removed by the South Sound Salmon Enhancement Group.

Squaxin Island has documented surf smelt spawning habitat in that area. Removal of the treated wood and over water structures will improve the habitat for the smelt, as well as other species, such as migrating salmon.

Large structures that are built in the nearshore environment have been known to cast large shadows in the shallow waters that are used for migrating fish. These shadows are seen as a threat causing the fish to swim around them into deeper water where predators can eat them.

By keeping the nearshore clear of overwater structures that block sunlight and don’t contain toxic chemicals, we can help improve migratory corridors for our fish that we depend on.

South Sound Salmon Forecast and Squaxin Annual Regulations

It’s time to get your boats ready and gear mended because fishing season is just around the corner.  We are expecting to see some good returns of Fall Chinook  with approximately 19,500 expected to come back to Tumwater Falls Hatchery this year.   The coho season was a real downer last year with record low returns but the forecast looks promising with expected net pen coho returns to be around 51,000.

Fall chum numbers look to be lower this year from last with 264,000  coming back to our region.  Being an odd year, escapement goals for Totten Inlet (Kennedy) will be 11,500 chum and Eld Inlet (McLane & Perry) will be 14,500 chum.

2011 Deep South Sound Salmon Forecast

You should  see some Pink salmon dipping down in our waters.  South Sound Pink returns for Puyallup and Nisqually are expected to be around the million mark.

Squaxin Island Tribe fishing regulations are available on the web! Currently we have no fisheries open, but when we do open for fishing all emergency regulations will be posted on our website.

Arcadia Boat Launch Closure

The long-awaited reconstruction of the Arcadia Boat Ramp will begin in early July.  Fishermen and clam diggers please be aware that the ramp will be closed to all traffic during the construction period and use of the parking lot will be limited.
The 2011 Tribal Canoe Journey Launching and the First Salmon Ceremony will be held on the recently acquired Collier property, located on the point just north of the construction site.
The badly damaged existing ramp will be replaced with a new two-lane ramp long enough to allow access at lower tides.
For information, contact: Dan Neelands, Construction Manager @ 360-432-3975, dneelands@squaxin.us
