Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

Our friend, Carnivore biologist John Laundre has written a "tomb" to our natural world that should be required reading in the halls of Congress, the Supreme Court and the White House...........Every Governor and state Representative, every state Wildlife Commissioner and every High School and College student, teacher and Professor should take John's "course" in how we are all a part of the circle of life including the big cats, bears and wolves that share our planet with us..................In fact, it is these large predators, (including us human animal predators) that help maintain the balance, health and positive ebb and flow of life on the one planet we all call home.................As another good friend, Cougar Rewilding's Chris Spatz recently told me, "JOHN LAUNDRE SHOULD RECEIVE A NOBEL PRIZE FOR HIS REVELATIONS, ANALYSIS AND SET OF COMMANDMENTS ON HOW WE SHOULD GO ABOUT REWILDING OUR WORLD"----Happy Sunday everyone and thanks John for your contributions!!!!!!!

Ghosts of the Appalachians 

or the Missing Actors? 

John Laundre;living alongsidewildlife.com

   











When we pass through 
the Appalachian Mountains 
along its vast 
extent from the humid
 southeast of Alabama and 
Georgia to the
 cold and barren of Nova
 Scotia and Newfoundland, 
we cannot help
 but marvel of its beauty
and extensiveness.  Unlike 
its western cousin,
 the Rocky Mountains, which 
is a mixture of
 forested ranges imbedded in
 a matrix of 
lowland shrub and grass
 ecosystems, the Appalachians
 are heavily
 forested mountains 
imbedded in what is likely one 
of the largest 
forest ecosystems in
 the world.  One can only
imagine the 
extensiveness of the original
 eastern forest, extending to
 the north
 as far as the tundra, to the
 south to the Gulf of Mexico
 and to the 
west until the beginning 
of the Great Plains.  It is this
 eastern "endless"
 forest that provided 
the opportunities and resources
 to the Earlier
 Americans who lived
 there for centuries.  It is also 
this bountiful 
forest that gave the 
European explorers who
 followed their toehold
 on the continent.
  Rich in plant and wildlife
 resources, the eastern
 forest likely had
 one of the highest densities
 of Earlier Americans
 in North America.  Even today,
 the eastern forest
 continues to support the highest
 density of Current
 Americans. 

    Much has been written about
 the destruction
 of the eastern forests by early
 European colonists
 and their descendants.  
However, today past
 abuses and 
cars of these earlier settlers
 have been covered
 over by an extensive
 mantel of young and thriving 
forest mixed in
 with verdant farmland.  In fact, 
the structure 
of the current forest ecosystem
 of the east is 
probably 
much like that before Europeans
 arrived, a
 mixture of open farmland and
 dense forest. 
Today, as in those earlier times, 
the open 
farmland provides areas 
of high productivity where many
 species 
of wildlife can find food 
while the forest provides shelter
 from the
 elements.  


    To the viewer's eye, it would
 seem that
 the eastern forests, 
especially the Appalachian
 Mountains, have
 returned to much 
of their former beauty and
 glory.  Even in
 the more populated 
areas of the East, the forest
 extends its fingers
 into the fringes
 of the cities.  It is only in the
 East that
 abandoned land quickly
 reverts to forest!  In these
 extensive forests
 all along the eastern 
seaboard, abundant wildlife,
 small song birds
 and mammals, larger 
turkeys, hawks, and even 
larger deer and bear,
 are again abundant
 in many parts of the 
Appalachian chain.  
Though much was lost in
 the past, the recuperation 
of the eastern 
forest ecosystem 
throughout the eastern 
seaboard makes it
 a true success story, 
a paradise gained!  All
 this in light of one
 of the highest human
 densities in North America!
            

    But has the Eastern Forest
 truly returned
 to its past glory as an 
ecosystem?  An ecosystem is 
not like a museum,
 not just a static
 collection of parts, plants
and animals.  It is a
 dynamic entity, one
 that constantly changes, 
grows, dies. All its
 parts have a function,
 a function vital to the health
 of the ecosystem.
  The plants of an 
ecosystem function as extensive
 solar traps, 
each day, month, year, 
capturing immense amounts 
of solar energy. 
 That energy is
 transferred along to other
 parts of the
 ecosystem in a cascading 
chain of actions reaching 
the smallest
 corners, maintaining the 
diversity of life found there.  
In each step,
 energy is transferred,
 energy is lost.  Eventually 
that energy
 passes out of the ecosystem, 
replaced by new waves of
 solar radiation.
  In a true sense, the 
function of an ecosystem is
 this transfer 
of solar energy from
 one component to the next. 
 It is this 
energy transfer that keeps 
the ecosystem "alive", 
maintaining its
 integrity and its diversity. 
            
    The role, then, of plants
 and animals
 in the ecosystem is in
 successfully performing 
this transfer. 
 This is no small task and
 like an elaborate play, is
 accomplished
 by a well choreographed
 cast of thousands, of millions, 
playing 
parts honed by millennia 
of co-evolution.  All this is 
carried out
 on the stage of the ecosystem,
 the physical, the biological
 props and
 scenery that we see.  For
 most of the players in this
 production
, theirs is a dual role, they 
capture that energy and pass
 it on to
 others.  They are both 
consumer and consumed, 
predator
 and prey.  Half of the 
ecologically important role
 of prey
 is to be eaten by their predators.
  In doing so, they pass their energy
 on to the next step, fulfilling
 their ecological mission. How this
 is all done is the intrigues, the 
sinuous plots of this elaborate play. 
 At each step, the predators,
 take the energy to the next level. 
Many of these predators, in turn,
 have their own predators, fulfilling 
their dual role.  That is how the
 system works. In each step, energy
 is transferred, energy escapes, 
leaving less energy for the next
 consumer, the next predator. 
         
    










What is that final passage 
of energy within the system? 
 Who are the ultimate or "top" 
consumers/predators?  It is the
 largest predators, the Wolves,
 the Cougars, the Lions, animals
 that normally don't have another
 predator trying to eat them. 
 The remaining energy that reaches 
them passes through their bodies,
 leaving the system.  These top 
predators, then become the critical,
 the climax actors in the final
 act of this ecological play.  It is 
through them this energy, initially
 captured by plants from the sun,
 flows, completing its run, its final
 curtain call. However, it is a never 
ending final call, a never ending
 play as new energy continues 
moving up, new prey, new predators,
 new actors, providing life, vitality,
 diversity to the stage of the
 ecosystem, the play of life. 
            
    








What happens if these top 
actors are missing?  Can the play 
go on?  Can a system fine tuned 
over evolutionary time whose function
 depends on each part being 
connected, continue to work in the 
absence of its climax actors?  
We have ample evidence that suggests
 not.  Predators in general
 and large ones in particular, have 
always bore the brunt of
 humans' dislike and scorn.  Viewed
 as villains rather than 
stars in the play of life, they have
 always been the first to be
 removed from the stage.  This has
 happened not only in the
 Eastern forests but in most ecosystems
 in the world.  What
 has happened in these ecological plays
 when the top actors
 have been removed?  Without predators, 
the energy flow 
become blocked and can no longer flow
 upward.  The blockage
 of this energy flow, as with the blockage
 of a river or of any 
flow-through system, the flow backs up, 
disrupting the system,
 the ecosystem.  It concentrates in the
 form of excess numbers
 of consumers, normally prey for higher
 levels, and it builds up.
  Like a volcano building up pressure 
and eventually exploding
 in a series of violent eruptions, 
destroying the mountain, increasing
 consumers destroy the ecosystem.  
In Yellowstone National Park, 
removal of the Wolf led to an over
 population of Elk, leading to
 losses of plant species Elk preferred,
 to losses of other species
 dependent on these plants,  to 
eventual losses of Elk who starved 
and died under their own population
 weight.  Yellowstone changed 
from a smooth flowing river of energy
 to one of fits and starts, of
 energy blockage, a system of violent
 cycles.  This pattern has 
repeated itself many times over, the 
Kaibab plateau after the 
removal of Cougars, the Moose on
 Isle Royale, introduced 
without their predator, the Wolf.
  To remove the top predators
 in these ecosystems was an ecological 
crime, committing these
 systems to a slow agonizing death.
           
  








 How about the Appalachian 
forests?  Is the cast of ecological 
players complete? Unfortunately,
 the East is also missing its star
 performers, Wolves and Cougars, 
having been long killed out by 
our well-meaning but misguided 
ancestors.  All that remains are
 the ghosts of these past performers,
 apparitions that seemingly appear
 periodically but are of little 
substance.  Regardless of all these
 ghostly sightings, real or
 otherwise, the cold fact remains,
 the Wolf and Cougar are
 ecologically extinct in the 
Appalachians.  In the absence of 
these actors, the stage is set for
 a different script.  Without 
Wolves and Cougars, their main
 prey, White-tailed Deer,
 have returned with a vengeance, 
in many eastern states 
numbering in hundreds of 
thousands to millions of animals.  
Each of these individuals ravenously 
eat around 1,500 pounds
 of plants per year.  As a result,
 the eastern ecosystems are 
time bombs waiting to explode.
  Some have already; after years 
of excessively high deer densities, 
forest flowers and animals 
dependent on them are disappearing
.  As importantly, 
tree seedlings, the forest 
of the future, are also vanishing
 under the constant chewing of 
millions of deer.  The ecological
 fabric of the Appalachian 
ecosystem is unweaving before our
 very eyes.  What we see in the
 verdant, seemingly vibrant forests 
is a façade hiding a rapidly decaying 
stage of life, burdened by too 
many prima donnas.  What we see is
 not an endless play of life but 
a short-lived tragedy doomed to failure.

   







The fact is clear, 
the Appalachian play is missing
 its star performers and an 
ecological disaster is unfolding on 
the stage.  Can the ending
 of this play be changed by bringing 
back the stars?  Can it be 
as simple as that? Scientifically, 
the answer is a resounding yes.
  However, before society agrees,
 many questions need to be 
answered.  The first of which is: 
can Wolves and Cougars still
 survive on the modern stage 
that is the Appalachians of today? 
 If so, what are some of the dangers, 
if any, of them coming back.
  After all, aren't they large and 
dangerous animals??? 
 If we agree that they should come
 back, how do we as a
 society help them back?  These
 and many more questions 
I hope to address in future posts
 to this blog.

I was born and raised in 
the Midwest (Wisconsin) and received
 my bachelors and
 masters degrees there.  I received my 
PhD from Idaho 
State University in 1979.  Since then,
 I have been working 
in large mammal predator-prey
 ecology for over 30 years
 and have studied predators and 
their prey in the western 
U.S. and northern Mexico.  My 
experience includes working
 with cougars, wolves, coyotes,
 bobcats, deer, elk, bison,
 and bighorn sheep.  I have
 conducted one of the longest
 (17 years) studies of cougar
 ecology and behavior to date
 and have published over 15 
scientific articles both on this
 work and work conducted in 
Mexico.  I am the originator 
of the concept of the landscape 
of fear that proposed that
 fear of prey for their predators
 drives many, if not all 
ecological processes.  The one 
important aspect of this
 concept is that predators
 become instrumental in 
maintaining the balance 
between prey species and 
their habitat, not so much 
by killing their prey but
 affecting how they use the
 landscape.  I am the author 
of the newly published book, 
Phantoms of the Prairie: The

Hemlock forests which are under siege from the asian Wooly Adelgid sucking insect are now faced with a new threat....................Our bloated Whitetail Deer population is overloading hemlock deeryards with an overload of nitrogen from their urine.............Hemlocks are historically slow growers and the "vitamin-laced" nitrogen from the Deer pee stimulates the growth of other tree and plant species(e.g Sugar Maples), resulting in baby hemlocks being outcompeted...................................Pumas and Wolves needed back in the landscape to place a check on deer.

Too much deer pee changing northern forests

By Becky Oskin

LiveScience.com; fosnews.com
  • White-tailed deer congregate under evergreens like northern white cedar for protection from winter weather, creating nitrogen hot spots that change the plant community. (Michigan Technological University)

The booming deer population in the northern United States is bad for the animal's beloved hemlocks, a new study finds.
During Michigan winters, white-tailed deer converge on stands of young hemlocks for protection from winter chill and predators. The same deer return every year to their favorite clumps of the bushy evergreens, called deeryards. The high concentration of deer in a small space saturates the soils with nitrogen from pee, according to a study published online in the journal Ecology.














While deer pee can be a valuable source of nitrogen, a rare and necessary nutrient for plants, some deeryards are now too rich for the hemlocks to grow.

"Herbivores like deer interact with the ecosystem in two ways. One is by eating plants and the other is by excreting nutrients, said Bryan Murray, an ecologist and doctoral student at Michigan Tech University.

Urine can be a really high nitrogen resource, and hemlock can be out-competed by other species in really high nitrogen environments."

Slow-growing hemlocks prefer low-nitrogen soil, and the prolific pee results in nitrogen-loving species like sugar maple outgrowing the hemlocks, the researchers found.

Hemlocks are already struggling to recover from logging and other ecosystem changes that reduced their numbers to 1 percent of pre-settlement populations in some parts of Michigan, Murray said. "At the moment, it's difficult to find hemlock stands where there are saplings in the understory that are going to replace the hemlocks in the overstory when they die," he told OurAmazingPlanet. The lack of regeneration could be due to a number of issues, but deer overpopulation is a factor, he added.

With the reduced hemlock cover available for deer, the booming white-tailed deer population means more deer crowd into the remaining forest. The researchers found more than 100 deer per square mile in popular deeryards. And young hemlocks have a tough time recovering from the deer nibbling and browsing.
In the eastern United States, an invasive sap-sucking bug called the adelgid is also killing off hemlocks.

"The Upper Midwest represents one of the last strongholds of hemlocks," Murray said.

Outdoor writer and naturalist George Wuerthner, PREDATOR DEFENSE "captain" Brooks Fahy, Biologist John Laundre and many other contributors to this blog often cite their opinions on why they(and I) do not feel there is any justification in the 21ast century for hunting and trapping carnivores..............................And as we have seen in Yellowstone and other locales where Wolves reside, diseases such as mange and parvovirus in combination with space and prey restrictions bring an ebb and flow to Wolf populations that keep them in a rough equilibrium with the land.....................As Oregon has begun to repopulate with Wolves, Pavovirus has sprung up and is beginning to make it's impact felt..............................

Field Reports: Oregon wolf dies from parvovirus

    spokesman.com

 The first case of parvovirus in Oregon wolves has been documented by the Oregon State University Veterinary Diagnostic Lab.
The wolf known as OR19, found dead by Oregon Department of Fish and Wildlife biologists on May 19, died of complications of canine parvovirus, according to the lab's preliminary report.
The disease is contagious in canids and usually fatal. Domestic dogs usually are protected by vaccinations, but parvo has been found in wolf populations throughout the West, causing short-term wolf declines, state officials said.









Once common in the Champlain Valley(northwestern Vermont), the Timber Rattlesnake hangs by a thread to survival in two isolated pockets in Rutland County(central Vermont)..............Researchers are now also facing the recently documented "fungal disease" that is killing rattlers across their range.................Like whitenose syndrome that has decimated bat populations east of the Mississippi, the snake disease most likely is caused by the accumulated environmental assault that we humans have relentless waged on the natural world,,,,,,,,,,,,,,,,,Global warming, chemicals of all sorts-------As Bill Maher often states on his late night HBO program,,,,,,,,,,,,,,,let us exhibit some humility and fess up to the havoc we are causing rather than hiding our heads in the sand and pretending that some "mysterious" force is responsible for these problems

VF&W works to recover Vermont's timber rattlesnakes

mountaintimes.com

RUTLAND COUNTY- The Vermont Fish & Wildlife Department has been working with researchers at The Nature Conservancy and the Orianne Society to conserve a piece of Vermont's unique natural heritage, the timber rattlesnake. They have captured rattlesnakes from the wild and implanted radio transmitters under their skin as part of a two-year study of timber rattlesnake habitat and movements in western Rutland County.

The researchers have also been working to determine the extent and severity of a condition referred to as 'snake fungal disease' that has recently begun afflicting Vermont's timber rattlesnakes. Snake fungal disease causes blisters or brown, crusty lesions on the face and neck of infected individuals.










Biologist Doug Blodgett leads the timber rattlesnake project for VF&W. "We first documented the lesions on timber rattlesnakes in 2012," said Blodgett. "Since then, the condition has been observed in several species of snakes throughout Vermont. It's difficult to assess the effects of this disease on individuals, but it does appear to be associated with population declines in neighboring states."

Timber rattlesnakes are one of 11 species of native snakes in Vermont. They once ranged throughout the Champlain Valley, but are now found only in two isolated populations in western Rutland County.

The fate of timber rattlesnakes in Vermont is uncertain. The loss of critical habitat, collection for the black market pet trade, and indiscriminate killing have depressed populations to state-endangered status, and snake fungal disease may exacerbate these problems.

 Together with other snake species, timber rattlesnakes help control rodent populations, which would cause crop damage and spread diseases such as Lyme without limits from predators.











"There's always been a strong cultural bias against rattlesnakes due to sensationalized Hollywood depictions of these animals as highly aggressive, stalking menaces of the forest," said Blodgett.  "Nothing could be further from the truth.  In my dozen years of experience working with rattlesnakes in Vermont, I've been most impressed with how docile, tolerant and secretive these animals are. They do just about anything to avoid confrontation with people."

Public perception of rattlesnakes is changing as people gain a better understanding of this species. Fear and hatred are giving way to interest and curiosity, as people begin to appreciate the important role that rattlesnakes play in the ecosystem.

While most rattlesnakes in Vermont remain in remote areas, they are occasionally found near people. VF&W urges Vermonters who find a rattlesnake in their yard to avoid handling the snake and to contact the Rattlesnake Removal Program at 802-241-3700 to have the snake safely relocated by a trained expert.

"These animals are the original native Vermonters. They've been here for thousands of years and are an integral part of our ecosystem and our wildlife heritage," said Blodgett. "I see them as a symbol of something still untamed and wild in a fairly tame landscape. They deserve our protection and stewardship."
