Unsup­port­ed claims in obscure essays from 1942, 1944, and 1960 have hurt a lot of peo­ple in south Thurston Coun­ty, Wash­ing­ton.  Oppres­sive laws are based on them—including the 2014 Endan­gered Species Act micro-list­ing of four Maza­ma pock­et gopher sub­species.  Some fam­i­lies have lost every­thing.

johnson-benson-snip-1-title-page-top-150x150A brief 1960 essay enti­tled  “Rela­tion­ship of the Pock­et Gophers of the Tho­momys Maza­ma-Talpoides Com­plex in the Pacif­ic North­west” (The Mur­relet, Vol. 41, No. 2, pages 17–22) is what fed­er­al, state, and local offi­cials still rely on to iden­ti­fy Thurston Coun­ty gophers as the Maza­ma species.   The top of this essay’s first page is shown at right.

This 1960 essay claims that the pock­et gophers liv­ing on the prairies around Thurston Coun­ty are not the same species as the sur­round­ing North­ern (talpoides) pock­et gophers—for an intrigu­ing rea­son.

Maza­ma Pock­et Gopher.  Zoo­log­i­cal Series, Vol.6

The essay states that, because of the alleged large size of these south Thurston gophers’ penis­es, they are actu­al­ly mem­bers of the well-endowed Maza­ma species.  That species was first dis­cov­ered in 1897 in the moun­tains and forests around Crater Lake, OR and north­ern Cal­i­for­nia, as shown at right.

Crater Lake was formed by the mas­sive erup­tion of Mount Maza­ma—hence the gopher’s name.

The only evi­dence of this 1960 claim are the com­par­a­tive gopher penis draw­ings in the fea­ture image shown above, and at low­er right.

There is no avail­able expla­na­tion as to how or why a small band of well-endowed for­est rodents would bur­row 350 miles across moun­tains, val­leys, and rivers, includ­ing the wide Colum­bia, to set­tle on Thurston Coun­ty prairies, which is a dra­mat­i­cal­ly dif­fer­ent habi­tat from their native moun­tain home.

Yet offi­cials at every lev­el of gov­ern­ment fierce­ly pro­tect the “Maza­ma” pock­et gopher “sub­species” of Thurston Coun­ty, based on their con­fi­dence in this 54-year-old sketch of gopher penis­es, shown at right.

Nei­ther Maza­ma or talpoides need a prairie habi­tat

Fed­er­al, state, and local offi­cials also rely on the 1944 essay, “Dis­tri­b­u­tion and Vari­a­tion in Pock­et Gophers, Tho­momys talpoides, in the State of Wash­ing­ton” (Amer­i­can Nat­u­ral­ist, Vol. 77, No.777, pages 308–333), for their sci­en­tif­ic cri­te­ria about pock­et gopher habi­tat.  They enforce strin­gent laws based on their asser­tion that pock­et gophers can’t live in forests.

1944 essay states that encroaching forests will cause extinction of gophers. “American Naturalist” Vol. 77, No. 777, pg. 314

1944 essay states that encroach­ing forests will cause extinc­tion of gophers. “Amer­i­can Nat­u­ral­ist” Vol. 77, No. 777, pg. 314

This 1944 essay states that Thurston County’s gophers can’t live in forests.  The essay went on to claim that these gophers were even doomed to extinc­tion because of forests encroach­ing on their prairie habi­tat, as shown at right.

This dire pre­dic­tion from 1944 is the basis of these gophers’ cur­rent “endan­gered” sta­tus.

Mul­ti­ple sci­en­tif­ic stud­ies have doc­u­ment­ed that both the Maza­ma and the “North­ern” (talpoides) pock­et gophers live and breed pro­lif­i­cal­ly in forests.  The North­ern pock­et gophers were one of the few old growth for­est ani­mals to sur­vive the erup­tion of Mount St. Helens.

So, whichev­er species Thurston County’s pock­et gophers turn out to be–either North­ern or Mazama–they sure don’t need prairie habi­tat to sur­vive.

WDFW chal­lenges ‘sub­species’ cri­te­ria

From first page of 1942 essay identifying three new “talpoides” gopher subspecies.

From first page of 1942 essay iden­ti­fy­ing three new “talpoides” gopher sub­species.

Fed­er­al, state, and local laws pro­tect­ing Thurston County’s “Maza­ma” pock­et gophers are based on the asser­tion that dis­tinct sub­species were dis­cov­ered by a young muse­um employ­ee named Wal­ter Dalquest in 1942.

Here is the com­plete two and a half page essay from 1942, claim­ing to iden­ti­fy three new North­ern (talpoides) pock­et gopher sub­species in Thurston Coun­ty.  The essay is fol­lowed by a one page chart of gopher mea­sure­ments:

1942 Essay – Three New Pock­et Gophers (Genus Tho­momys) from West­ern Wash­ing­ton

This 1942 essay states that phys­i­cal appearance–varying col­ors, sizes, and shapes–would iden­ti­fy a dis­tinct gopher sub­species.

From pg. 5 of 2013 Draft WDFW Mazama Pocket Gopher Status Update.

From pg. 5 of 2013 Draft WDFW Maza­ma Pock­et Gopher Sta­tus Update.

This asser­tion has been refut­ed by sci­en­tists, who have stat­ed that phys­i­cal appear­ance is deter­mined more by a gopher’s envi­ron­ment, rather than genet­ics.

This claim has even been refut­ed by Wash­ing­ton Depart­ment of Fish and Wildlife (WDFW) on page 5 their 2013 Draft Maza­ma Pock­et Gopher Sta­tus Update, at right.

(Note: On this same page, how­ev­er, WDFW still appar­ent­ly relies on the 1960 penis draw­ings to iden­ti­fy Thurston County’s gophers as being from the “Maza­ma” species.)

Even though WDFW rejects this 1942 essay’s under­ly­ing the­o­ry of what makes a sub­species, the agency still fights, inex­plic­a­bly, to pro­tect “sub­species” that were iden­ti­fied by using this same anti­quat­ed method that they clear­ly dis­cred­it.

1997 DNA tests show no sub­species iden­ti­fied in Thurston Coun­ty

In 1997, two Uni­ver­si­ty of Wash­ing­ton Zool­o­gists, Eleanor Stein­berg and Dana Heller, pub­lished Using DNA and Rocks to Inter­pret the Tax­on­o­my and Patchy Dis­tri­b­u­tion of Pock­et Gophers in West­ern Wash­ing­ton Prairies.  In this report, they chal­lenged the 1942 the­o­ry of mul­ti­ple gopher sub­species in the Thurston Coun­ty area, for two rea­sons.

On page 44, they dis­put­ed the 1942 asser­tion that phys­i­cal appear­ance deter­mined a subspecies—just as WDFW did, in 2013.

On pages 45–47, Stein­berg and Heller pre­sent­ed the results of DNA tests per­formed on some of Thurston County’s dif­fer­ent “subspecies”—and found no genet­ic dif­fer­ences.

As a result, Stein­berg and Heller assert­ed that, based on these DNA tests, there was no known evi­dence of pock­et gopher sub­species in the area.

This report has not stopped state, local, and fed­er­al pro­tec­tion of these unproven “sub­species,” with oppres­sive reg­u­la­tions and threats of crim­i­nal and civ­il charges.

Where’s the proof?

Larry Weaver

Lar­ry Weaver

All of these details may explain why WDFW won’t give Rochester real­tor Lar­ry Weaver his gopher blood back, after they sup­pos­ed­ly col­lect­ed it from his prop­er­ty for genet­ic research.

And these details may explain why Lar­ry Weaver’s son Chris was arrest­ed in 2010 by five armed WDFW offi­cers for admit­ting to trap­ping two gophers on his own prop­er­ty.

The five armed WDFW offi­cers took his bar­ren mole traps and his buckets–even though he may not have trapped a pro­tect­ed gopher.

Chris Weaver now has a crim­i­nal record for admit­ting to trap­ping two gophers that may or may not have been pro­tect­ed, with no evi­dence of his crime–thirteen years after the 1997 DNA tests results that showed no sci­en­tif­ic evi­dence of pock­et gopher sub­species in Thurston Coun­ty.

What was supposed to be a yard for a new home in Rochester, WA–until gopher laws took over.

What was sup­posed to be a yard for a new home in Rochester, WA–until gopher laws took over.

These details may also explain why south Thurston Coun­ty cit­i­zens face heavy civ­il and crim­i­nal charges if they trap their own gophers, to have them DNA test­ed.

The Weavers’ gophers may or may not have been a pro­tect­ed “sub­species.”

Their gophers may not have been from the ESA-list­ed Maza­ma species, from 350 miles away.

Yet the fed­er­al gov­ern­ment states that it doesn’t need DNA proof for an ESA list­ing as long as they ref­er­ence an author­i­ty with lit­tle cred­i­bil­i­ty, and Wash­ing­ton state can cre­ate sus­pi­cious doc­u­ments to hurt south Thurston Coun­ty cit­i­zens in the future.

The 1960 gopher penis draw­ings appear to be the only “proof” that the gov­ern­ment has of the Thurston Coun­ty gophers being mem­bers of the Maza­ma clan. The 1942 essay appears to be the government’s only “proof” of the exis­tence of sub­species, which was clear­ly chal­lenged 17 years ago, by the Stein­berg-Heller DNA tests.

DNA tests are the only way to val­i­date the results of the 1997 Stein­berg-Heller report about no gopher sub­species exist­ing in Thurston Coun­ty.

DNA tests are also the only way to prove whether Thurston County’s pock­et gophers are even mem­bers of the far away Maza­ma species, rather than the sur­round­ing “North­ern” talpoides species.

Unless some­one can find a real­ly good artist this time around.
