Rattlesnakes in New England By Ellen Heck
ThespeakerforJunewasKevinMcCurley,speak-ing about rattlesnakes in New England and the threat they are currently encountering. He has also written several books on ball pythons as well as breeding them,aswellasre-ticulated pythons and albino water monitors.
New England has pop-ulations of several ven-omoussnakes,includ-ing timber rattlers and copperheads. They face the same threats as most wildlife from the encroachment of people – loss of habitat and being killed out of hand because most people view them as athreat.However,Kevinshowedseveralshotsofhimfree-handlingrattlesnakes(notsomethinghe does a lot and NOT something that is recom-mended)todemonstratethataslongasyoudon’t“push their buttons” they will not overreact by biting. Kevin feels he can read the signs of an animal’sbehaviorandgaugeitsmood,althoughhe points out the Steve Irwin could as well and it worksuntilitdoesn’t.However,hesaysthattheytend to be as interested in him as he is in them.
Ironically,oneoftheproblemsfacingthesnakesisthehumanrace’sabilitytocontrolforestfires.Normally,thesewillburnthroughanarea,clear-
ing out brush and smaller trees. This is impor-tant,aslikemostsnakes,theyneedplacestobask. Kevin spends time clearing trees around primedensites,toprovidebaskingareas.Theburned areas also tend to have more rodent
activity,whichinturnattractssnakes.

Unfortunately,thesehavefallen victim to what appears to be a fungus infecting the snakes.Thisfungus,achryso-sporium,hasbeenseeninpygmy rattlesnakes in Florida as well as eastern massasauga insouthernIllinois.Itisfirstnoticeable in their faces and eyes as necrotic tissue.

lem if the snake in question is a gravid female. Itpreventstheeggsfromdevelopingcorrectly,resultinginslugs.Notjustrattlesnakesareaffect-ed;thefungushasalsobeenfoundinrat,waterand milk snakes as well.
It appears to affect the snakes while they are hibernat-ing. Kevin has observed snakes entering dens in the fall in perfect health and emerg-ing in the spring covered with sores. The im-mune system of a hibernating snake isnon-existent,which may be a factor. The fun-gus may die off at about 37 °F but since most dens remaininthe40’s,it is attacking the snakes the whole time. Kevin is currently tracking 2females,bothinfected with the fungus,whocan-not be allowed to hibernate.Iftheystart,theyareindangerofdy-ing. They were released in the spring with radio tracking devices. They will be collected in the fall,topreventtheirhibernating.
Some of the snakes appear to be infected with beauveriabassiana,anaturallyoccurringfungusthathasbeenmodifiedtobeusedasaninsec-ticide.Unfortunatelypartofitsmodificationmakes it resistant to UV radiation and tolerant of a wider temperature range.
Unfortunately,acceptanceoftheproblemandits possible causes has been slow. Although the snakesarebeingstudied,thereisatendencytoobserve,ratherthantopreserve,theanimals.
Their condition has been dismissed as rodent or birdbites,frostbiteorotherinjury.Withcasesbeing reported in more and more states however agencies are slowly rec-ognizingtheproblem.
Since it seems to be spread by sites rather than fromsnaketosnake,onestep would be to fumi-gate the dens after the snakes have emerged. This would allow the sites to be treated and aired before the snakes return in the fall to hibernate. This can also be done to densthatarenowempty,in the hope that with cap-tivebreeding,snakescanbe reintroduced to the sites. Providing den sites and re-establishing their habitat needs to be done as well.
