At least 11 donkeys have been found all in in Death Valley National Park . While the region has been bake by scorching hot temperature in itshottest summer on criminal record , utmost heat is not believed to be the culprit ( at least not directly ) .
The National Park Service ( NPS ) is currently investigating the donkey deaths , but they strongly suspect that atoxic alga bloomat the Owls Hole Spring is to fault .
“ I detest to see any animal suffer . The National Park Service is working to take away feral burros from Death Valley , for their own refuge and to reduce impact to aboriginal wildlife , ” Superintendent Mike Reynolds said in astatement .

The Owls Hole Spring is a stagnant body of water in Death Valley that supply the perfect experimental condition for algae and cyanobacteria to thrive , especially after a hot summer . In abundance , these micro-organism can release toxins that are harmful toanimal wellness .
The NPS has localize a foretoken at the Owls Hole Spring , discourage rambler that the water should be considered unsafe for humans or pets to drink or touch . They also caution that people and pets should not touch any of the gone donkeys .
The donkeys , akaburros , are not aboriginal to the national park and are the distant descents of African wild tail end ( Equua asinus ) from North Africa and the Arabian Peninsula . The 4,000 or so soul in the Death Valley National Park are all descendants of animals unloosen by miners during the Gold Rush .
Although the donkeys fall from removed lands , the declamatory herbivores fill an ecologic disruption shape at the end of the Ice long time when many of North America ’s megafauna were drive into extinction .
As an incursive species , the feral burros can stupefy problems for the local ecosystem . They eat A LOT of vegetation , which is sparse in the desert environs , and limit the amount of food available to aboriginal brute , such as Bighorn Sheep , desert tortoises , and germ - eating birds . They can also be very territorial and strong-growing , preventing other animals from access scarce water sources .
While there have been movement to wrangle the invasive burro , with child roundup have not been conduct out since 2005 due to a lack of fund . The Bureau of Land Management worked with the NPS to take away 43 burro in recent age and the non-profit-making Peaceful Valley Donkey Rescue has captured 256 burros from the Mungo Park since 2018 . Nevertheless , the universe stay on relatively unattackable .
The donkey do have born enemies , though . It was long assumed that the introduced equine had no natural predators , but a2022 studyhighlights how burros in the Southwestern US are preyed upon by cougars . The research worker reason that donkeys and big cats have make a strong ecological kinship that fills the nothingness left by the extinction of large prey andsabertoothed catsat the end of the Ice Age around 13,000 years ago .
“ Our results paint a picture , ” the survey concludes , “ that the conservation community should prioritize the protection of apex predators and the world ’s remaining megafauna , regardless of their nativeness . ”
