As part of a $ 63,000 enquiry project to devise young and in force ways of cut back the skyrocketing common iguana population in south Florida , wildlife officials in the state have started to smash in the head of iguanas , say it ’s a quick and “ humane ” form of euthanasia . Sounds dreadful — and it is — but the situation in Florida is more complicated than it appear .
Florida has an iguana problem . Over the past decade , the population of this incursive lounge lizard has absolutely exploded . aboriginal to Mexico and Central America , these herbivorous lizards were introduced to the commonwealth as PET , but they ’ve take the Sunshine State by tempest , munch on plants and prime in gardens , and damaging sidewalk and seawalls with their burrows . Many Florida resident now consider them as cuss , on par with rats and squirrel .
As Susannah Bryanreportsin the Sun Sentinel newspaper , conservationists from the University of Florida have embarked on a task to search new ways of reducing Iguana iguana population , while finding new tricks to aid homeowners keep the pests away . As Bryan drop a line :
A 15 - member team from the University of Florida is using a tool called a captive bolt grease-gun that transport a bolt into the brainiac , similar to what is used in the livestock diligence . They ’re also smash the creatures ’ heads against solid objects , including a truck and gravy boat they ’re using to track them down .
“ Most of what we ’re doing is outspoken force-out trauma , ” say Jenny Ketterlin , a wildlife biologist and inquiry coordinator with UF . “ hit their head very severely against a strong physical object . ”
destroy their brains apace is the most humanist way to belt down them , she enjoin . decollate the brute without anaesthesia would vote down them but not be considered humane .
Over a three month distich , the team has vote out about 250 iguanas along a canal in Davie , a town in Broward County near Fort Lauderdale where the researchers are based . Ketterlin says the head - bashing technique falls within the bounds of Florida ’s animal cruelty law .
Other extermination technique have been rejected because they ’ve been deemed insecure , inefficient , unproven , or even crueler than nous bashing . For lesson , deadly chemicals , such as Halothane , Isoflurane , and Sevoflurane , have to dispense by a veterinarian ( so it ’s very time consume ) , they take up of 20 minutes to kick in ( unlike in mammal , who feel the issue within a minute ) , and the safety visibility of these drugs has yet to be find out . immobilise Iguana iguana used to be considered okay , but research suggests it create painful sparkler crystals in the lizard ’ brains . Decapitation has likewise been rejected , as cognisance can hang in for upwards of a full minute after an iguana ’s head has been chop off .
“ Appalling , ” Lori Marino , the founder and executive managing director of The Kimmela Center for Animal Advocacy , tell Gizmodo . “ This is not conservation in any measure . It ’s extermination . There is nothing humane about ending the lives of healthy creature . The University of Florida researcher should be ashamed of themselves . ”
Joe Wasilewski , an iguana expert and wildlife biologist based in Princeton , Florida , say there ’s no perfectly humane mode to kill any live being , but until something better come along , this method acting is among the better options .
“ search , we drink down millions upon millions of strikebreaker and cockroaches each year , ” he tell Gizmodo , enounce aggregated liquidation of pests are usual . “ The last thing I need to do is injury one . I ’ve spent my whole career trying to ameliorate their island habitats , but the sheer number of iguanas is explode — it ’s a situation that ’s not get better any fourth dimension soon . ”
Wasilewski said he ’s not surprised the media is track down with this story , admitting he also cringed when he try that conservationist were blast in iguana head . “ But in less than a second these lizards go from being aware to completely utter , ” he said . “ Is that cruel ? ”
That say , Wasilewski is hoping other kill methods will eventually be entertained . The claim that freeze do unspeakable internal-combustion engine crystalsmay have been debunk in 2015by researchers from the University of Sydney , he pointed out . Also , his team is currently enquire chemical methods , but monish the proficiency is “ not perfect yet . ”
For homeowners who desire to keep iguana away , Wasilewski recommends trim back botany , and plant flowers and plants that do n’t attract the voracious lounge lizard . Other measures include removing rocks or other shelter smudge which iguanas use for protection .
As to why the iguana population is suddenly skyrocket in Florida , Wasilewski says scientists still do n’t know . He enounce it could be climate change related , and/or something to do with shifts in botany . He ’s not trusted , but what he does know is that Florida ’s iguanas search incredibly healthy . So level-headed , in fact , that females — who lay upwards of 50 to 60 eggs per nest — are able to lay a second batch during a individual breeding season .
“ This means their growth is practically exponential , ” say Wasilewski .
