New orca baby doing well, closely linked
to 43-year-old female

The young killer whale born into J pod three weeks ago still appears to be doing well, according to Dave Ellifrit of the Center for Whale Research, who observed the calf when her pod came through the San Juan Islands on Monday.

In his written notes, Dave said the calf, designated J-50, was staying close to J-16, a 43-year-old female named “Slick.” Meanwhile, Slick’s daughter, 16-year-old J-36 or Alki, remained some distance away.

Uncertainty has surrounded the question of whether J-16 is the mother or the grandmother of the new calf. If she’s the mother, it will be the first time that an orca over 40 has been known to give birth, at least among the three pods that frequent Puget Sound.

As Dave noted in his observations:

“While all the J16’s traveled together, J36 was consistently the farthest of the group from J50, so whatever doubts remained about J16 being the mother are about gone.”

Ken Balcomb, who founded the Center for Whale Research, was not with Dave during the encounter. Ken agrees that current evidence points to J-16 being the mom, but he is still not totally convinced.

“I’m staying open,” he told me. “J-16 is certainly the primary caregiver.”

There remains a little matter of the “rake marks” on the back of the baby orca — most likely caused when an adult whale used its teeth to pull the newborn from the birth canal. A 16-year-old female might need some help during delivery, Ken explained, and the grandmother was the likely one to assist. Such help probably would not be needed for an older mom, he said.

I thought that the proof of motherhood would come when we knew who was nursing the baby. While nobody has directly observed any nursing behavior over the past three weeks, the baby is fattening up and staying near enough to J-16 to allow such things to happen.

But Ken says it is possible that J-16 could be lactating — even if she is the grandmother. It’s happened in older pilot whales, he noted.

“It is not beyond the realm of possibility that a grandmother could play the nurse-maid role,” he said.

There will be no certainty about the lineage, he said, until genetic testing is performed, and that could take years — assuming the calf survives. Such tests could come as the result of fecal sampling or a skin biopsy performed by approved researchers following the whales, he said.

Meanwhile, since the calf was born, J pod has been moving around the inland waterways and well up into the Strait of Georgia in Canada, as revealed by a satellite transmitter carried by J-27, a 24-year-old named Blackberry.

Jan. 17-21. To save battery power, the satellite transmitter began sending signals every other day. Still, it was clear that the J pod whales traveled south from Texada Island and passed through the San Juan Islands by Monday afternoon of this week. From there, they made a straight run to the ocean, then turned around on Tuesday and headed back into the Strait of Juan de Fuca by yesterday afternoon. This time, they were accompanied by K pod, according to observers. Map courtesy of NOAA

A couple times in the past two weeks, the whales went through the Strait of Juan de Fuca and into the Pacific Ocean. But each time they quickly turned around and came back,

Last night, Mark Malleson of Prince of Whales, a whale-watching company, observed J pod along with K pod spread out in the Strait of Juan de Fuca near Sheringham Point near the south tip of Vancouver Island, according to his report posted on Orca Network’s Facebook page.

So far today, I have not heard any more reports, and the next satellite data won’t be available until later.

Earth gets hot in 2014, breaks record for average temperature

UPDATE, Jan. 20, 2015
Some people apparently are skeptical about whether 2014 was actually the warmest on record. They cite probabilities provided by government researchers to support their skepticism. But at least some skeptics seem confused about the meaning of this statistical uncertainty.

Andrew Freedman of Mashable tackles the subject in a straightforward way. But the best point in his piece comes in the final paragraph:

At the end of the day, the discussion about a single calendar year obscures the more important long-term trend of warming air temperatures, warming and acidifying oceans along with melting ice sheets, all of which are hallmarks of manmade global warming. Including 2014, 13 of the top 15 warmest years have all occurred since 2000.

—–

Last year turns out to be the hottest year on record for the Earth’s surface, according to climate researchers who analyzed average temperatures across the globe.

The year 2014 adds yet another dramatic page to the record book, which now shows that the 10 warmest years since 1880 have occurred since the year 2000 — with the exception of the record year of 1998, which now stands as the fourth warmest on record.

The data were released this morning, with additional information provided in a telephone conference call with scientists from NOAA — the National Oceanic and Atmospheric Administration — and NASA — the National Aeronautics and Space Administration. The two agencies conducted independent analyses of their data, coming to the same conclusion about the record year of 2014.

Across the Earth, the average temperature in 2014 was 1.24 degrees Fahrenheit above the annual average of 57.0 degrees F, with records going back to 1880. That breaks the previous records of 2005 and 2010 by 0.07 degrees F. It’s also the 38th consecutive year that the annual global temperature was above average.

Since 1880, the Earth’s average surface temperature has warmed by about 1.4 degrees Fahrenheit, mostly driven by an increase in carbon dioxide and other greenhouse gases released into the atmosphere, the researchers said. Most of the warming has come since the 1980s.

Gavin Schmidt, director of NASA’s Goddard Institute of Space Studies, made this comment in a prepared statement:

“This is the latest in a series of warm years, in a series of warm decades. While the ranking of individual years can be affected by chaotic weather patterns, the long-term trends are attributable to drivers of climate change that right now are dominated by human emissions of greenhouse gases.”

Although some skeptics have raised questions about whether global warming has been occurring in recent years, Schmidt said any short-term pause does not change the overall trend. In fact, the temperature rise seen for the past year fits perfectly onto a graph of the decades-long trend line for temperature rise.

temp graph

Ocean conditions such as El Nino or La Nina can affect temperatures year-to-year, Schmidt said. Since these phenomena can cool or warm the tropical Pacific, they probably played a role in temporarily “flattening” the long-term warming trend over the past 15 years, he added, but last year’s record-breaking temperatures occurred during a “neutral” El Nino year.

This past year was the first time since 1990 that the global heat record was broken in the absence of El Nino conditions during the year. If El Nino conditions are present at the end of 2015, the researchers said the chances are high that the record will be broken again this year.

As I mentioned in yesterday’s post in Water Ways, strong regional differences were seen last year in the contiguous United States, with several western states experiencing record highs while the Midwest suffered through an abnormally cold winter. Other cold spots can be seen on the global map, but the hot spots more than balanced them out to break the heat record.

global temps

Much of the record warmth of the Earth can be attributed to record heat accumulated across the oceans. The average ocean temperature in 2014 was 1.03 degrees higher than the longterm average of 60.9 degrees, breaking previous records set in 1998 and 2003.

Record months for ocean temperatures were seen from May through November, with January through April each among the all-time top seven, while December was the third warmest December on record. The all-time monthly record was broken in June of last year, then broken again in August and again in September. Such sustained warmth in the ocean has not been seen since 1997-98 — during a strong El Nino.

On the land surface, the average temperature was 1.8 degrees higher than the long-term average of 47.3 degrees F, or the fourth highest average land temperature on record.

Europe is expected to report that 2014 was the warmest year in at least 500 years, according to information from the World Meteorological Organization. Last year surpasses the previous record set in 2007. Much of that warmth can be attributed to the second-warmest winter on record, followed by a record-warm spring.

According to the WMO report, 19 European countries have reported or are expected to report that last year was their hottest year on record. They Austria, Belgium, Croatia, the Czech Republic, Denmark, France, Germany, Hungary, Iceland, Italy, Luxembourg, The Netherlands, Norway, Poland, Serbia, Slovakia, Slovenia, Sweden, and the United Kingdom.

Around the world, precipitation was near average for 2014, the third year that near-average precipitation was measured for land-based stations.

1. 2014, 1.24 degrees above average

Overall, last year was very warm in Washington state

Last year, Washington state experienced its fifth-hottest year in 120 years of records maintained by the National Oceanic and Atmospheric Administration.

Meanwhile, records for average temperatures were broken in California, Arizona and Nevada, which lived through the highest averages in 120 years. Oregon had just one hotter year on record, while Idaho had three years with higher averages.

Temps

In Washington, the average temperature for the year was 48.4 degrees Fahrenheit, or 2.3 degrees above the long-term average. Hotter years were 1934 with 49.1 degrees; 1958, 49.0 degrees; 1992, 48.7 degrees; and 1998, 48.6 degrees. In 2004, the average temperature was 48.4, the same as this year.

California’s record high was based on an average temperature of 61.5 degrees, with Arizona at 62.3 and Nevada at 53.1. Oregon’s average of 49.5 degrees was exceeded only in 1934, when the annual average was 49.9 degrees.

For the nation as a whole, the average temperature in 2014 was tempered by some fairly extreme low temperatures in the Midwest, stretching into the Mississippi Valley. For the contiguous United States, the average temperature was 52.6 degrees — 0.5 degrees higher than the long-term average and tied with 1977 as the 34th warmest year on record, according to information from NOAA’s National Climatic Data Center.

Despite several months of record and near-record lows across the middle of the country, no state had an annual average that set a record for cold or even ranked among their five coolest years.

For the contiguous U.S. as a whole, last year was the 18th year in a row with an average temperature above the 120-year average. The last year with a below-average temperature was 1996. Since 1895, the temperature has risen an average of 0.13 degrees F per decade.

Precipitation across the contiguous U.S. was 30.76 inches last year, or 0.82 inch above the 120-year average. That makes it the 40th wettest year on record. On average, precipitation has increased by 0.14 inch per decade.

Precip

For Washington state, 2014 was the 16th wettest year on record. The average across the state was 48.73 inches, some 6.7 inches above the 120-year average.

Above-average precipitation occurred across the northern states last year, while the Southern Plains and Central Appalachians experienced below-average conditions.

Drought conditions continue in California, despite near-average annual precipitation. Exacerbating the problem is a three-year rainfall deficit combined with record-high temperatures this past year.

Meanwhile, drought conditions improved across the Midwest and Central Plains, though both improvements and declines were observed in various parts of the Southern Plains, Southwest and Southeast.

Washington state had its fourth-wettest spring on record, while Kansas had its third-driest spring. Other seasonal conditions can be found on the NCDC’s “National Overview” for 2014. The “Climate at a Glance” page can help you break down the data by state and time period.

Global data and analyses from NCDC are scheduled to be released tomorrow.

Agency lists critical habitat for endangered Puget Sound rockfish

National Marine Fisheries Service has designated more than 1,000 square miles of Puget Sound as “critical habitat” for rockfish — a colorful, long-lived fish decimated by over-fishing and environmental problems.

In Hood Canal, we know that thousands of rockfish have been killed by low-oxygen conditions, and their populations have been slow to recover because of low reproductive rates. Elsewhere, rockfish are coming back with mixed success, helped in some locations by marine protected areas.

The final designation of critical habitat was announced today in the Federal Register for yelloweye rockfish and canary rockfish, both listed as “threatened” under the Endangered Species Act, and bocaccio, listed as “endangered.”

The critical habitat listing includes 590 square miles of nearshore habitat for canary rockfish and bocaccio, and 414 square miles of deepwater habitat for all three species. Nearshore areas include kelp forests important for the growth and survival of juvenile rockfish. Deeper waters are used for shelter, food and reproduction by adults.

Potential critical habitat was reduced by 15 percent for canary rockfish and bocaccio and by 28 percent for yelloweye rockfish. Most of the excluded area was deemed already protected, either by tribes near their reservations or by the military near Navy and Army bases and their operational areas.

The designated habitat overlaps in large part with existing critical habitat for salmon, killer whales and bull trout. The only new areas added without overlap are some deep-water areas in Hood Canal.

Under the law, federal actions within designated habitat must undergo consultations with the National Marine Fisheries Service. Such actions — which include funding or issuing permits for private development — cannot be approved if they are found to be detrimental to the continuing survival of the species.

Catherine Kilduff of the Center for Biological Diversity offered this comment about the habitat designation in a news release:

“Saving rockfish from extinction requires protecting some of the most important places they live, and that’s exactly what’s happening now in the Puget Sound. These habitat protections will not only give rockfish a fighting chance at survival but will help all of the animals that live in these waters.”

The three species of rockfish were placed on the Endangered Species List in 2010, following a series of petitions by biologist Sam Wright. Last year, the Center for Biological Diversity notified the National Marine Fisheries Service of its intent to file a lawsuit over the agency’s delay in designating critical habitat.

Federal and state biologists are now working on a recovery plan. I have not heard whether they still hope to get the plan completed next year.

Rockfish are unusual among bony fishes in that fertilization and embryo development are internal. Female rockfish give birth to live young. After birth, the larval rockfish may drift in shallow waters for several months, feeding on plankton. Among the listed species:

  • Canary rockfish can reach up to 2.5 feet in length. Adults have bright yellow to orange mottling over gray, three orange stripes across the head and orange fins. They can live to be 75 years old.
  • Bocaccio can reach up to 3 feet in length. They have a distinctively long jaw extending to the eye socket. Adult colors range from olive to burnt orange or brown. Their age is difficult to determine, but they may live as long as 50 years.
  • Yelloweye rockfish can reach up to 3.5 feet in length and 39 pounds in weight. They are orange-red to orange-yellow in color and may have black on their fin tips. Their eyes are bright yellow. They are among the longest lived of rockfishes, living up to 118 years.

A 2011 plan for saving the rockfish was written by the Washington Department of Fish and Wildlife with assistance from a group of experts. The report, “Puget Sound Rockfish Conservation Plan” (PDF 706 kb), identifies the cause for the population declines:

“These declines have largely been caused by historical fishing practices, although several other stress factors play a part in their decline. Rockfish in urban areas are exposed to high levels of chemical contamination, which may be affecting their reproductive success. Poor water quality in Hood Canal has resulted in massive periodic kills of rockfish as well as other species. Lost or abandoned fishing nets trap and kill large numbers of rockfish.”

The plan identifies these objectives to restore the population:

  • Place the highest priority on protecting and restoring the natural production of indicator rockfishes to healthy levels,
  • Promote natural production through the appropriate use of hatcheries and artificial habitats,
  • Protect and restore all marine habitat types for all rockfish species,
  • Manage all Puget Sound fisheries to ensure the health and productivity of all rockfish stocks,
  • Protect and restore existing functions of rockfish in the complex ecosystem and food web in Puget Sound,
  • Conduct monitoring of indicator stocks to evaluate stock status and management actions,
  • Implement new research to understand the diversity, biology and productivity of indicator rockfish, and
  • Conduct a strategic outreach and education program to inform Washington citizens of the value of rockfish stocks and to promote ecotourism.

Unmanned aircraft provides unique views of killer whales

Unmanned aerial vehicles, commonly called drones, could play an increasing role in killer whale studies, according to Brad Hanson, a researcher with NOAA’s Northwest Fisheries Science Center who has been studying Puget Sound’s orcas for years.

Brad said a plan to use UAVs (he doesn’t like “drones”) has been on the drawing board for several years. Unmanned aircraft can fly over the whales far more cheaply than a full-size helicopter, which has been used in the past. The small aircraft also may be able to come in close for biological samples with less disturbance to the whales than when operating from a research boat.

“I’ve been looking at this for a long time,” Brad told me. “We have it in our (Endangered Species Act) permit to be able to use a UAS (unmanned aircraft system).

Remote-controlled aircraft have been used by researchers to study seals and penguins in the Arctic and to estimate their populations with less disturbance than approaching the animals on the ground. They’ve also been used to count birds in remote areas.

In August, NOAA and Vancouver Aquarium researchers teamed up to test the use of a remote-controlled hexacopter as they observed Northern Resident killer whales in British Columbia. Mounted with a high-resolution camera, the copter captured some amazing videos and still pictures, including those on this page. See also NOAA’s website.

One can learn a lot from a good aerial view of a killer whale, including general body condition, Brad told me. From a boat on the water, it is often difficult to tell if an orca is healthy, underweight or pregnant. From above, a whale’s girth is easier to assess.

Researchers involved the British Columbia study — including John Durban of NOAA’s Southwest Fisheries Science Center and Lance Barrett-Lennard of Vancouver Aquarium — identified several females who seemed to be pregnant.

They also spotted two whales that seemed emaciated. Those animals later went missing and are presumed dead, confirming that they were in poor health. What is not evident from photos, however, is the cause of the problem, Brad Hanson said. Were the whales suffering from disease, injury or another problem that caused them to lose weight, or was it simply a lack of food?

Aerial photos also can be used to measure the length of a whale and, over time, determine the growth rate at various periods in its life.

Brad said the ultimate goal is to develop health assessments for the Southern Residents, listed as “endangered” under the federal Endangered Species Act. A lot of technical details need to be worked out, he said, but the plan is to use unmanned aircraft to collect breath and fecal samples from the whales.

A breath sample is the next best thing to a blood sample, Brad told me, and fecal samples provide information about stress hormones, potential pathogens and other things.

“If you tied that in with imaging, we might be able to build individual health profiles and begin to understand when something is going wrong,” Hanson said.

Currently, breath samples are taken by driving a boat alongside the whales and holding out a pole with an apparatus on the end. Fecal samples are taken by following the whales and sifting feces from the water.

If a small helicopter flown from a boat some distance away can be used, the result would be less intrusive than a boat coming near the whales.

In the study in British Columbia, the general goal was to keep the UAV at least 100 feet above the whales. The study also included some closer movements to test the reaction of the whales. No obvious changes in behavior were noticed, Brad said.

One permit still is needed for Hanson to operate a UAV in Washington state. The Federal Aviation Administration must issue a certificate of authorization, or COA, which spells out limitations of the flight to avoid other aircraft operating in the area.

The Canadian experiment received similar permits from Fisheries and Oceans Canada and Transport Canada. The aircraft was an APH-22 marine hexacopter built for NOAA by Aerial Imaging Solutions.

Ironically, amateurs in the United States are allowed to operate unmanned aircraft in some areas without permits. But flying around wildlife could create unanticipated problems for the animals. And anyone operating around endangered whales could be in violation of other state and federal laws — such as the Endangered Species Act or Marine Mammal Protection Act — if they fly below 1,000 feet.

Amusing Monday: Students create environmental art

This week, I’d like to share some student artwork from two contests.

One is a local event in which 10 Kitsap County students are honored in the Kitsap Recycles Day contest, sponsored by Kitsap County Public Works. The other contest is for students anywhere in the country. Called the Keep the Sea Free of Debris contest, it is sponsored by the National Oceanic and Atmospheric Administration.

Li-Nelshin Co, a fifth grader at Esquire Hills Elementary School, created one of the winning posters for Kitsap Recycles Day.
Li-Nelshin Co, a fifth grader at Esquire Hills Elementary School, created one of the winning posters for Kitsap Recycles Day.

The first poster featured on this page is by Li-Nelshin Co, a fifth grader at Esquire Hills Elementary School, located in East Bremerton and part of the Central Kitsap School District.

Li-Neishin wrote this about the poster:

“Recycling is important because we are saving the world for future generations. My favorite thing to recycle is PAPER because this way we are not only recycling, we are also saving the trees that gives us fresh air, shade, preventing soil erosion.”

Other winning posters can be viewed on Kitsap Recycles Day webpage.

A couple years ago, the Kitsap Recycles Day poster contest was moved from November to February and expanded into a broader educational program. The delayed contest allowed teachers and/or parents to provide more information than could have been completed by America Recycles Day, celebrated in November. A new activity book, “Close the Loop” (PDF 16.7 mb), is part of Kitsap’s expanded program.

“It’s incredibly encouraging to see the influx of posters we see on Kitsap Recycles Day,” said Kitsap County Recycling Coordinator Christopher Piercy in a news release. “You can tell each student has a passion for recycling, reducing waste, and the environment. It is especially fascinating to see the grasp they all have on the value of ‘closing the loop’ — not just recycling, but buying recycled content products.”

The other winners are Libby Parker, kindergartener at Gateway Christian Schools, Poulsbo; Natalie Oathout, first grader at Emerald Heights Elementary School; Jeddison Miller, second grader at Crosspoint Academy; Kelsey Derr, third grader at Hilder Pearson Elementary School; Saige Herwig, third grader at South Colby Elementary School; Charlotte Halbert, fourth grader at Gateway Christian Schools, Poulsbo; Blake Warner, fifth grader at Crosspoint Academy; Drew Moar, sixth grader at Manchester Elementary School; and Gia Acosta, eighth grader at Our Lady Star of the Sea Catholic School.

The second poster on this page, a winner in the 2014 Keep the Sea Free of Debris contest, was drawn by Jessica D., a fourth grader in New York.

Jessica commented:

“Keep the sea free of debris. Debris is garbage, marine debris is garbage in the sea. Marine debris is very bad. Marine debris is mostly plastics, fishing gear and litter. Marine debris is very harmful and dangerous to undersea creatures. This pollution can ruin habitats. Marine wildlife can get hurt by marine debris. It also can cost a lot of money to fix. But you can help fix it by just cleaning beaches and not littering.”

The contest is sponsored by NOAA’s Marine Debris Program, which asked contest entrants to create their “vision” of marine debris. All 13 winners and their comments can be seen on a Gallery Page on the Marine Debris Blog.

NOAA opens its catalog of nautical charts

Chart

More than 1,000 U.S. Coast Guard nautical charts have been released for public use at no charge.

What started out as a three-month pilot program by the National Oceanic and Atmospheric Administration has become a permanent service. The free charts, which are offered in PDF format, are especially valued by recreational boaters.

During the trial period, nearly 2.3 million charts were downloaded, according to Rear Admiral Gerd Giang, director of NOAA’s Office of Coast Survey.

“To us, that represents more than two million opportunities to avoid an accident at sea,” Giang said. “Up-to-date charts help boaters avoid groundings and other dangers to navigation, so our aim is to get charts into the hands of as many boaters as we can.”

If you know the name of the waterway you wish to explore, the fastest way to get a chart is to search the list of available PDFs.

To help users zero in on the charts they need, NOAA has created a website called the Interactive Chart Locator. From there, one can view an image of the chart; download a PDF version of the entire map; or choose a blown-up version with numerous maps of the same area, known as a “booklet.”

NOAA also has begun offering its Raster Navigational Charts, a composite of all the charts formatted for zooming in on a specific location. That is especially useful for viewing on a computer screen or mobile device. Free software and viewers from third-party sources also are listed on the RNC webpage.

NOAA’s Office of Coast Survey is the nation’s nautical chartmaker, according to information provided by the agency. Created by President Thomas Jefferson in 1807, the office updates charts, surveys the coastal seafloor, responds to maritime emergencies and searches for underwater obstructions that pose a danger to navigation.

The Coast Survey’s Twitter handle is @NOAAcharts. A blog — noaacoastsurvey.wordpress.com — provides information about the agency’s ongoing activities.

Chinese TV discusses shellfish import ban

U.S. officials say they have not heard a word from Chinese health authorities since the Washington State Department of Health sent test results showing that geoducks from Puget Sound are safe to eat.

A ban on shellfish imports from the Northwest continues. By all accounts, it appears that U.S. shellfish exporters will miss a chance to provide geoducks, oysters and other shellfish to China during lucrative Chinese New Year celebrations next week.

The National Oceanic and Atmospheric Administration has sent the health department’s test results to China, NOAA spokeswoman Connie Barclay told me yesterday. “We will continue to work with folks to see if we can resolve this issue,” she said.

Meanwhile, Chinese Central Television (CCTV), a government-sponsored TV network in China, has produced a video describing the issue, including the economic effects on shellfish growers. It’s a pretty straightforward piece, but offers no hint about what further steps may be taken by the Chinese government.

For background, see my last entry in Water Ways on Jan. 9. which includes links to other sources. The same goes for an entry on Dec. 24 and the first one on Dec. 17.

The bottom line is that nothing has happened for weeks. Shellfish growers are waiting patiently, hoping this does issue does not grow into an extended trade dispute.

Researchers attach new tag to orca in L pod

A research team led by Brad Hanson of NOAA’s Northwest Fisheries Science Center has been tracking K and L pods off the coast of Oregon and California, most recently offshore of Washington’s Willapa Bay.

Map by Robin Baird with NOAA data

The team left Newport, Ore., on Friday aboard the 209-foot research vessel Bell M. Shimada. The crew caught up with K pod the following day with the help of a satellite transmitter attached to K-25, according to reports. Most if not all of L pod was seen swimming with the K pod whales near Cape Blanco, off the southern coast of Oregon.

The research team attached a new satellite tag to L-88, a 20-year-old male named Wave Walker. The new tag will provide another method of following the whales if the tag attached to K-25 should fall off, as expected sooner or later. It has already stayed attached for more than two months, about twice the average life of the satellite tags.

I have not yet connected with Brad Hanson, but I talked to Robin Baird of Cascadia Research, who has been getting reports from the crew. Robin told me that the researchers have been able to obtain multiple fecal and/or fish-scale samples on most of the days they have been at sea.

Those samples will aid in meeting the primary goal of the cruise, which is to figure out where the whales are going and what they are eating during the winter months while away from Puget Sound.

The satellite tags have allowed the research ship to stay with the whales even when the weather and their lack of vocalizations have made them hard to find, Robin said. As a result, this research cruise has been more efficient than past ones in terms of both time and fuel.

The research trip, which was scheduled for 21 days, will be cut in half because of the federal spending cuts related to the sequester, according to a statement issued by this afternoon by the Northwest Fisheries Science Center.

The travels of K-25 over the past two months are shown in an animation produced by staff at Northwest Fisheries Science Center. (In my browser, the north and sound portions of the map are cut off even in full-screen view, but the movements shown are still amazing.)

The latest report shows both tagged whales swimming offshore of Willapa Bay on the Washington Coast, having crossed the Columbia River mouth this morning. The full trip can be viewed on maps posted on the website called Southern Resident Killer Whale Satellite Tagging.

Steelhead listing brings protection to smaller streams

The little streams and tributaries on the Kitsap Peninsula and elsewhere in Puget Sound are destined for special attention under a proposal to designate critical habitat for Puget Sound steelhead. See my story in today’s Kitsap Sun.

When it comes to endangered and threatened species, most of the attention has been given to Puget Sound chinook, which migrate to the larger rivers and often spawn in mainstem waters and larger tributaries.

As a reporter, I’ve also paid attention through the years to Hood Canal summer chum, which come into the streams along Hood Canal in the late summer and early fall. They generally spawn in the lower part of the streams, because water has not yet arrived to fill upstream tributaries.

Steelhead are an entirely different kind of fish, coming into our local streams in the winter months and swimming upstream as far as they can go. Steelhead may not die after spawning, so they can repeatedly return to spawn again and again.

With adequate rains, there is almost no place on the Kitsap Peninsula where steelhead cannot go. In that respect, they are similar to coho salmon, a fall spawner that remains on the borderline for listing under the Endangered Species Act. Many biologists tell me that protections for steelhead will go a long way to protecting our depressed coho runs as well.

What is needed more than anything is more research on the ecological values of the smaller streams on the Kitsap Peninsula and South Sound region. Where have steelhead been found historically, and what can we do to improve the habitat for them?

On the positive side, it is often easier to fix the smaller streams. Culverts can be replaced, side channels created and streamside vegetation planted, all at less cost than on our major rivers.

On the other hand, given our tight state and federal budgets, we are not likely to see more money for salmon and steelhead restoration. We’ll probably have to spread the existing dollars further. In fact, I’ve been told that some people in chinook territory have tried to slow down the steelhead-recovery effort, because it will mean less money for chinook recovery. And they may have been successful.

Puget Sound steelhead were listed as “threatened” nearly five years ago. The Endangered Species Act calls for designating critical habitat within one year of the listing, but NOAA concluded that the designation was “not determinable” at that time. Now, more information is available, the agency says.

Elsewhere, five populations of West Coast steelhead were listed as “threatened” in August 1997, and four others were listed in March 1998. Critical habitat for all nine listed species of steelhead was proposed in February 1999 and completed a year later. (Their status was later reconsidered, which led to the official listing date actually coming after designation of critical habitat.) As a result of a lawsuit, the court scheduled the deadlines for those steelhead.

Biologists are now working on a recovery plan for Puget Sound steelhead in consultation with local governments throughout the region. The ESA does not provide a firm deadline for approving a recovery plan, although federal agencies attempt to get them done within a few years after listing.
