Just three wolves exist on Michigan’s Isle Royale , from a high of nine the final year, revealed Michigan Technological University scientists said on Friday.
It was found out during Michigan Tech’s annual winter survey at the almost virginal 206 mile island , a U.S. National Park in North Lake Superior.
It would be no surprise if no wolves would exist in the freezing winter says Michigan Tech ecologist John Vucetich , member of the wolves stay survey team.
“It really is like asking if a particular person on their deathbed is going to die tomorrow or the subsequent day,” he mentioned. “I don’t know, but the significant point is they are on their deathbed.”
About 40 years ago , wolves migrated to the island by crossing a frozen Lake Superior in winter. The wolf population was 50 and was down to an average of 25 decades ago before the population reduced because of physical and reproductive impacts in breeding.
In a 2013 video , from the Lansing State Journal , investigator Rolf Peterson who has been studying the wolves for 40 years , says the wolves face an unpredictable future and is a fronliner of the battle to preserve the wolve’s existence.
“What is definitely vital here is not the presence of wolves, per se,” Vucetich said. “But the wolves need to be in a position to carry out their ecological function — predation. Predation has been primarily nil for the past 4 years now.”
Subsequently , a 22% raise in the mooses population was noted every year of the past four years.
The wolf reduction was discovered to be of common organic causes, says Vucetich. One of the wolves that died was an eleven year old “alpha female” leaving behind a pack of 3 wolves . What was left were two adult wolves who were dependent on the wolf who died. The other wolves that were left were 1 and 2 years old . “When wolves are that age, if factors aren’t going properly for the pack, their survival can be affected,” Vucetich stated.
The last three surviving wolves are probably or mated pair and their offspring , he quipped.
In an attempt to preserve the wolf population in the island , Vucetich and a colleague Rolf Peterson , conducted a “genetic rescue” by bringing in wolves from other places to beef up the number of island wolves and for breeding purposes. It the said genetic rescue fails, which is approved by the Forest Service it could result in bringing in a completely new pack within the island.
Colorado resident Mary Hughson Brown , an Escanaba native sighted a wolf in the island and felt good about it knowing they still exist .
“You lose part of the spirit of the island, I think,” she stated.
