Just Like Falling Dominoes
IT'S A SIMPLE EXAMPLE
With A Complex Result
see the ecological transformation of
flathead lake
-------
.. By now, it would seem, that interested and informed fly fishers are aware of the Lake Trout situation in Yellowstone Lake. They are probably aware of the rapidly vanishing native species in Yellowstone National Park, as well... Sadly many of our neighbors, (guides and feather merchants as well,) have poo-pooed the need to do anything about the conservation of native species. They say, sadly: "A trout is a trout, is a trout. I just want to catch them."

| Opossum Shrimp |
.. We read with great interest the recent article in NEW WEST. The story is about the complex interaction of species in Flathead Lake.
.. A recent paper published in the Proceedings of the National Academy of Sciences details how the introduction of a small non-native crustacean, (the Opossum Shrimp - Mysis diluviana,) has totally altered the ecology of a large lake.
.. It has changed algae production, nearly eliminated Kokanee Salmon, enabled Lake Trout population explosion, and endangered the native Bull Trout.
.. The paper details a classic example of a trophic cascade that has been well documented since it's inception in 1968.

| LAKE TROUT |
.. Their population explosion provided an abundant food source for the introduced Lake Trout and allowed the Lake Trout population to grow to the point where the Kokanee Salmon and the Bull Trout are now being eaten at a rapid clip by the Lakers.
.. Another by product of the trophic cascade is the increased growth of algae.
.. We note that "simple" is seldom a concept that can be applied to ecological change. Both Yellowstone National Park and Flathead Lake, (as well as many other areas around the country and the world,) have suffered the consequences of actions in the past.MONEY QUOTE:"After the mysis explosion kokanee disappeared, bull trout declined, and lake trout came to be the dominant top predator, according to the study. This led to an increase in algal production because the shrimp ate up larger zooplankton, decreasing their levels and allowing smaller types of zooplankton to proliferate, Stanford explains. He says this changed the way the zooplankton “mow the lawn,” or consume algae: smaller zooplankton are less efficient consumers and allow algae room to grow."
.. "While the future might hold unexpected outcomes, for now fisheries managers have their hands full dealing with the legacy of shrimp and a misinformed decision from the past."

Short Time Coming
KISS YOUR FELT GOODBYE
And Your Ass Too ?
will you sterilize your rubbers ?
-------
.. Briefly: Montana introduces legislation to ban felt soled waders. Check out the posts at The Trout Underground and comments at The Headhunter. Read carefully the comment by Earl James. We're not home free yet!.. The tons of soil and supposed included micro organisms moved around by wading fishers is documented in a masters thesis from MSU, (LINK.)
.. The proposed amended Montana Legislation is HERE. And, just like the U.S. Congress exempts itself from many of the laws it makes, Montana exempts it's employees and emergency personnel from the ban. Is there a message here?
.. We're sure that this is not a cure all; and, further believe that the wader manufacturers still need to go a long way into providing better gripping rubber, (or whatever,) soles.
.. We predict that sales of the wading staff will skyrocket in the near future.
.. We also predict that there will now be less cleaning of wading gear, (including the newly-sold wading staffs,) than prior to the legislation
.. How about some legislation mandating the cleaning of wading gear? See how far that boat floats!

Short Fuse, Comments Needed
20 YEAR EFFORT
Comment Now
no whiners
-------
.. The NATIVE FISH CONSERVATION PLAN is designed as a major effort to respond to the diminished stocks of native fish in Yellowstone National Park... The Environmental Assessment is now open for public comment.
.. Mark your calendars; only two public meetings are scheduled:
* Bozeman, Montana: January 5th from 6:00 to 8:00 p.m., at the Comfort Inn, 1 370 North 7th Avenue.. Written comments may be submitted through the project web site, in person, by mail, or at either of the scheduled public meetings. Comments will not be accepted by phone, fax, or e-mail. All public comments must be received or postmarked by midnight, January 31, 2011.
* Cody, Wyoming: January 6th from 6:00 to 8:00 p.m., at the Holiday Inn, 1701 Sheridan Avenue.
.. Here are the important Links:

.. The scoping meeting in West Yellowstone last April was poorly attended. No feather merchants were present, one local guide was present, and a handful of concerned fishers attended... Input by these few interested parties helped shape the current document that is now open for review.
.. The EA addresses Lake Trout in Yellowstone Lake, other invasive species throughout the rivers in the park, the effects of climate change on native species, and disease.
.. Conservation efforts addressed include: increased gill netting in Yellowstone Lake, establishing barriers and weirs, removing non native species, restoring native populations, and a host of other actions including poisoning fish populations.
.. The key concept is conservation. The actions taken to implement this can be extensive, varied, and vast.
.. It's important that input at this time be concise, reasoned and rational. It will help steer the project and will certainly affect the fishscape of the future.
.. Please understand that, at base, this addresses the question of "What Is The Purpose Of Yellowstone National Park." Several guides have remarked that it does no good to replace one trout with another. They are just concerned with catching any fish.
.. Many guides and fishers of the park will be voicing opinions that catching fish, (the more - the better,) is what the park should provide.
.. There are others that feel it's important to remove all invasive species such as Rainbow Trout, Brown Trout and Brook Trout to foster the recovery of native Cutthroat Trout & Grayling(?).
.. Many feather merchants feel that the role of Yellowstone National Park is to provide fishing opportunities for recreational fishing, (and an economic base for their enterprise.)
.. Some conservationists believe that the only way to enable preservation of native fish is to "restore" the park to "natural" conditions, including removal all planted stocks of fish, (which is a large segment of the current fishable populations.)
.. Definition of terms and concepts will be argued and explored at the public meetings and in the submitted comments. Many oxen could be gored by this project.
.. The subtext of comments will be interesting to observe, as will the rationale behind the proposed actions in those comments.
.. Some fishers of Yellowstone have opined that since Brown Trout have been in the rivers for over 100 years that they are "native."
.. Does that make Lake Trout native if they survive another 70 years?
.. In another 100 years what will the descendants of those fishers say about Rock Snot, New Zealand Mud Snails, and other yet unforeseen invasive species?
.. As the waters warm will we see Yellowstone become a trophy fishery for Carp and Chubs and Largemouth Bass?
.. What will happen if some fool decides to dump Northern Pike or Muskellunge or Lake Trout in Hebgen Reservoir, right at Yellowstone's door?
.. Your input is necessary for the decision making process. We're talking about the future and how history will view the legacy that we leave.
.. Make no mistake about it, this is a significant project. It will last for 20 years, (1/5 of the next 100 years.) It will significantly affect the definition of Yellowstone National Park and it's role in species conservation and recovery.
.. It will also determine who fishes where and for what in the park. It is an historic effort that demands you input and your concern for how Yellowstone is defined: a fun and profitable fishery for visitors seeking "non-native," invasive trout or a refuge for indigenous species - or both.
