SUBJECT: Alsea Valley Alliance v. Evans -- listing distinct population segments of salmon and steelhead under the Endangered Species Act [revised version of 9/18 memo]

The decision

By now you have all seen or at least heard about a recent court decision out of the federal district court here in Oregon (Judge Michael Hogan) concluding that NMFS’ 1998 decision to list Oregon coast coho as threatened under the Endangered Species Act was arbitrary and capricious and inconsistent with the ESA. Alsea Valley Alliance v. Evans. The court declared the listing "unlawful," remanded the matter to NMFS "for further consideration consistent with [the court’s] opinion," and directed the agency "to consider the best available scientific information, including the most recent data, in any further listing decision concerning the Oregon cost coho salmon." A copy of the decision is attached.

At the Spokane meeting John Ogan and I will brief the Council on what the decision says and what might be some implications for the listings in the Columbia. Here is a brief summary of the decision:

The Endangered Species Act assigns NMFS the responsibility for determining if anadromous fish species are endangered or threatened. The ESA defines "species" to include "any distinct population segment of any species of vertebrate fish or wildlife which interbreeds when mature." The ESA does not define "distinct population segment," nor provide further guidance or limits on what such a segment might be.

NMFS established the "ESU" (or "Evolutionary Significant Unit") policy as a way to interpret and apply the concept of a "distinct population segment" to Pacific salmon. That is, a specific stock or group of chinook or coho or steelhead can be recognized as a separate ESU, and thus as a "distinct population segment" for purposes of consideration for listing, if the stock is "substantially reproductively isolated from other conspecific population units" and "represents an important component in the evolutionary legacy of the species." It is on this basis that while we may have just a handful of species of Pacific salmon (e.g., chinook, coho, sockeye, chum, pink, steelhead), we have dozens of ESUs and thus dozens of distinct population segments considered for listing or listed. Also, NMFS adopted a second policy that recognized that hatchery populations may be considered part of an ESU when there is genetic, geographic and life-history interaction with wild stocks. But the policy also specifies that hatchery populations, even if within the ESU, should be excluded from listing unless they are "essential for recovery" -- indicating that the role of the hatchery populations in an ESU in a listing determination was not whether those hatchery fish counted (my term) in determining the listing status of the ESU, but only whether the hatchery fish might have a role in the recovery of the populations in the wild.

With regard to Oregon coast coho, NMFS defined the ESU to include not only the naturally spawning coho in these coastal streams but also the coho from nine hatcheries in these streams. NMFS included these hatchery stocks in the ESU largely because of the origin of these fish in the natural runs in the area and because of the life-history and reproductive interaction of these hatchery spawners with the natural spawners. But then when NMFS listed the Oregon coast coho as threatened, it limited the listing to only the naturally spawning coho. In other words, NMFS listed as threatened only one part of the ESU -- the naturally spawning coho -- and excluded the other part of the same ESU -- the hatchery coho population. NMFS decided not to include the hatchery stocks in the listing decision because NMFS did not consider the hatchery fish essential to the recovery of the ESU.

Judge Hogan concluded that the ESA did not allow NMFS to make this additional distinction, that the ESA requires NMFS to consider the ESU as a whole (that is, the "distinct population segment" as a whole) when deciding whether that ESU is threatened or endangered. In other words, once NMFS determined what fish were part of the ESU or distinct population segment, that unit as a whole was what the ESA called upon NMFS to consider for listing and either list or not list in its entirety. If the hatchery coho are part of the ESU, the hatchery coho have to be included with the natural spawners when deciding whether to list the ESU.

What the court decision did not hold: (1) The court did not tell NMFS that it cannot list the Oregon coast coho as threatened, only that NMFS wrongfully failed to consider the ESU as a whole when making its listing determination. (2) The court did not hold that there is no difference between a hatchery produced fish and a naturally spawning fish, only that when NMFS made the distinctions between the two when listing at a level or division below the ESU level, this took the listing decision to a level not allowed by the ESA. (3) And, the court did not hold that NMFS was correct or incorrect to establish an ESU policy that linked hatchery spawners and natural spawners in the same ESU, or that NMFS was correct or incorrect to include the hatchery stocks in this specific ESU -- the determination as to what went into the Oregon coast coho ESU was taken as a given, and the issue decided was whether NMFS properly considered that ESU as a whole in making the listing decision.

I do not know whether the United States will appeal this decision to the Ninth Circuit. We have new administration personnel at NMFS and elsewhere who may or may not be inclined to pursue this particular approach to considering ESUs for listings. As far as I can tell, no group or individual intervened the case on the side of NMFS (Oregon Trout filed an amicus brief). If so, if the U.S. does not appeal, the decision will not go up for review. I do think the basic legal analysis by Judge Hogan is sound and even rather mechanical, if he is correct about how NMFS did not consider the hatchery fish in determining whether the ESU should be listed. It may be the United States has a viable argument that the hatchery fish were part of the listing decision in some way, but I don’t know of it.

Questions relevant to assessing the implications for the Columbia ESU listings

There are 12 ESUs of Pacific salmon listed in the Columbia River system. In assessing the effect of this decision on those listings (assuming this decision is not appealed, or not reversed if appealed), you have to consider two threshold questions:

(1) Similar factual circumstances? The first and most obvious question is whether any of the Columbia listing decisions fit the same fact pattern as the Oregon coast coho listing -- that is, where NMFS designated hatchery stocks as part of the ESU but then did not include the hatchery stocks when deciding to list the ESU.

I have looked at the Federal Register notices for the listing decisions for the 12 Columbia ESUs, and I can give you some preliminary information as to which ESUs included hatchery stocks and whether those hatchery stocks were part of the listing determination or not. This will indicate which ESUs are within the category of listings called into question by the new decision. But I cannot tell you for sure, without study of the record of the listing decisions, whether in fact these hatchery stocks were in some way considered in the listing decisions in a way that might take that listing out of the fact category of the Oregon coast coho.

The Columbia ESUs that appear to fit within the category of listing decisions with facts similar to the Oregon coast coho listing include Snake River steelhead, middle Columbia steelhead, lower Columbia chinook, lower Columbia steelhead, upper Willamette chinook, upper Willamette steelhead, and Columbia chum. The list in full:

Snake River spring/summer chinook (listed 4/92) -- no hatchery stocks designated as part of the ESU; left as an open question for the future

Snake River fall chinook (4/92) -- no hatchery stocks designated as part of the ESU; left as an open question for the future

Snake River sockeye (11/91) -- no hatchery stocks designated as part of the ESU

Snake River steelhead (8/97) -- NMFS defined the ESU to include the Dworshak, Imnaha and Oxbow hatchery stocks, but not the Lyons Ferry, Pahsimeroi, East Fork Salmon or Wallowa hatchery fish. The hatchery stocks that are part of the ESU were not included in the listing of the Snake River steelhead ESU as threatened. So this ESU appears to fall into the category that Judge Hogan found of concern in the Oregon coast coho case -- an ESU that was further subdivided in the listing decision.

Upper Columbia spring chinook (3/99) -- NMFS defined six different hatchery stocks as part of the ESU, while four hatchery stocks in that area were deemed not part of the ESU. But NMFS then declared the hatchery stocks within the ESU to be "essential for recovery" of the ESU, and thus NMFS included these hatchery stocks in the listing determination for the ESU as endangered. This is quite different from the Oregon coast coho listing, in which the hatchery populations in the ESU were not listed -- here, NMFS listed the ESU as a whole (an issue that will surely arise is how NMFS considered the hatchery populations in coming to its listing decision). NMFS defines the upper Columbia spring chinook ESU as the spring-run chinook "in all river reaches accessible to chinook salmon in Columbia River tributaries upstream of the Rock Island Dam and downstream of Chief Joseph Dam in Washington, excluding the Okanogan River."

Upper Columbia steelhead (8/97) -- NMFS defined the Wells hatchery stock as part of the ESU, and declined to include the Skamania stock in the ESU. As with the upper Columbia chinook, NMFS then included the Wells hatchery stock in the listing determination for the ESU as endangered. Thus this listing is also different from the Oregon coast coho listing faulted by Judge Hogan. NMFS defines the upper Columbia steelhead ESU as those steelhead in the Columbia system above the Yakima River.

Middle Columbia steelhead (3/99) -- NMFS defined the ESU to include the Deschutes and Umatilla hatchery stocks. But the hatchery stocks that are part of the ESU were not included in the listing of the Middle Columbia steelhead ESU as threatened, so this ESU fits the facts that Judge Hogan found of concern in the Oregon coast coho case. NMFS defines the middle Columbia steelhead ESU as the steelhead in the Columbia system above the Wind and Hood rivers up to and including the Yakima River.

Lower Columbia chinook (3/99) -- NMFS defined this ESU to include 14 hatchery stocks, and not to include another nine hatchery stocks in the area. NMFS did not include the hatchery fish within the ESU in the designation of the ESU as threatened, so this is another listing that fits the challenged fact pattern.

Lower Columbia steelhead (3/98) -- another ESU that fits the challenged fact pattern, NMFS defined this ESU to include hatchery stocks from the Cowlitz and Clackamas; did not include five other hatchery stocks in the ESU; and then did not include the hatchery stocks that are within the ESU in the determination of the ESU as threatened.

Upper Willamette chinook (3/99) -- NMFS defined the ESU to include five hatchery stocks (North Fork Santiam, North Fork Willamette, McKenzie, South Fork Santiam and Clackamas), but did not include these hatchery fish in the designation of the ESU as threatened -- another listing that fits the challenged fact pattern.

Upper Willamette steelhead (3/99) -- another ESU that fits the challenged fact pattern, NMFS defined this ESU to include one hatchery stock from the North Fork Santiam; did not include two other hatchery stocks in the ESU; and then did not include the hatchery stock that is within the ESU in the determination of the ESU as threatened.

Columbia River chum (3/99) -- the final ESU that fits the challenged fact pattern, NMFS defined this ESU to include Grays and Cowlitz hatchery stocks, but did not include the hatchery stocks that are within the ESU in the determination of the ESU as threatened.

One phenomenon you are certain to see in the next few weeks will be assertions or arguments that the listing decision for any particular ESU matches or does not match the facts in the case before Judge Hogan. Those who favor a particular listing decision are likely to reach to finds grounds for distinguishing their listing of interest from the Oregon coastal coho listing decision. Vice versa, those interested in undoing a particular listing will undoubtedly find reasons why that listing decision raises the same concerns as the Oregon coast coho listing.

(2) What is the legal status of the Columbia listings? Could someone challenge the listings that appear vulnerable under the facts and holding in the Alsea Valley case, and if so, how? Judge Hogan’s ruling applies only to the Oregon coast coho listing. No listing in the Columbia (or Puget Sound or California) is automatically undermined or vacated by this decision, even if the fact pattern of the listing is the same as the Oregon coast coho listing. And as far as I know and can find out, there are no pending lawsuits challenging the legality of the Columbia ESU listings.

However, the time period for launching a direct challenge to most of the ESU listing determinations in the Columbia may still be open. As described in Judge Hogan’s opinion, the general statute of limitations that applies to civil actions against the federal government applies to ESA cases. The period is six years. Nine of the 12 ESU listings in the Columbia occurred in 1997 or later, less than six years ago. So it seems possible for people to file direct challenges to these listings. On the other hand, it does not appear legally possible to collaterally challenge the validity of a listing when a federal agency takes an action to address the needs of a listed population, such as in a Section 7 consultation or biological opinion, or an application of the "4d" rules, or in a take situation, although people will assuredly try.

I can imagine that NMFS will be under significant pressure to review on its own motion all of its Pacific salmon ESU listings. And I suspect private citizens and groups will also prod NMFS in this direction by filing petitions for delisting ESUs on these grounds. As part of any review of current listings, it seems to me that NMFS will probably need to rethink its overall ESU policy, especially how to understand the relationship between hatchery fish and naturally spawning fish in deciding what is an appropriate "distinct population segment" of Pacific salmon under the ESA. So, it is possible the ESUs will remain as they are, but NMFS takes another look at whether to list or not, or it is possible NMFS may have to reconstruct the Pacific salmon ESUs.

On the other hand, NMFS cannot simply pull back from or vacate the existing listing decisions. NMFS adopted these listing decisions as final rules under the notice-and-comment rulemaking procedure specified in the Administrative Procedures Act. NMFS would have to follow the same procedures to review and change any Columbia ESU listing, and that takes time.

(3) Question concerning ESU listings that did include the hatchery populations in the listing itself.

I am already beginning to hear arguments for how the Alsea Valley decision might call into question ESU listings even in those cases in which NMFS included the hatchery stocks not just in the ESU but also in the listing, such as occurred with the upper Columbia chinook and steelhead ESUs. The argument is this -- NMFS’ hatchery/ESU policies led NMFS to consider the hatchery populations in the ESU only to the extent to which those populations might be useful to the recovery of the naturally spawning fish. The listing decisions were still based only on the strength or health of the naturally-spawning fish, not on the basis of the entire ESU. In other words, the hatchery fish did not "count" (again, my term) on their own terms in deciding whether the ESU as a whole should be listed. And so, the argument goes, these listings may also be invalid for not really taking into consideration the entire ESU in deciding whether to list the ESU.

This kind of argument or challenge may or may not have merit on its own terms, but I am not persuaded of the relevance of the Alsea Valley decision in making the case. Judge Hogan’s opinion, as I noted above, seems to be quite mechanical: The statute calls on NMFS to either list or not list the ESU (or distinct population segment) as a whole, without further dividing the population. NMFS split the ESU in listing Oregon coast coho. This is not permissible under the ESA -- try again. In the upper Columbia chinook and steelhead ESUs, the ESUs as a whole are listed, so there is not the obvious and mechanical inconsistency with the statute.
