- Throughout Sri Lanka, municipal waste is frequently discarded in open rubbish dumps, a lot of that are situated close to protected areas and different wildlife habitat, drawing elephants there looking for meals.
- The deaths of a number of such foraging elephants has garnered international consideration, because of a current AP information report tweeted out by Leonardo DiCaprio, however native conservationists say they’ve been warning about the issue for a very long time.
- A former head of the Division of Wildlife Conservation says choices on the place to determine new dump websites typically ignore wildlife issues, pushed by “short-sighted, politically motivated” planning.
- However simply retaining the elephants out of the dumps isn’t an answer; many of those animals are accustomed to raiding native farms for crops — a behavior that they in a short time return to when dump websites are shut down, resulting in yet one more downside of human-elephant battle.
COLOMBO — It took a tweet from Hollywood famous person Leonardo DiCaprio to convey the difficulty of trash-foraging elephants in Sri Lanka to international consideration. However native conservationists have lengthy been flagging the issue, one they are saying is rooted in “short-sighted, politically motivated” planning that continues to take its toll on each elephants and other people.
On Jan. 26, Oscar winner and environmentalist DiCaprio tweeted to his practically 20 million Twitter followers a report by the Related Press on the rising downside of untamed Asian elephants (Elephas maximus) dying after feeding in open rubbish dumps. Elephants are revered in Sri Lanka, and sometimes characteristic in cultural and spiritual occasions. But most of the animals feed alongside stray canines and crows at these rubbish dumps, a lot of that are situated close to conservation websites and different protected areas which can be dwelling to wildlife.
“We performed a survey round Sri Lanka and listed 54 rubbish open rubbish dumps visited by elephants,” Chandana Sooriyabandara, director-general of Sri Lanka’s Division of Wildlife Conservation (DWC), instructed Mongabay. “The division has nothing to do with the establishing of those rubbish dumps, however we’ve to finally cope with them as elephants frequent the dumps. We try to reduce the influence, however it’s an uphill job as 70% of Sri Lankan elephants may also be discovered outdoors protected areas.”
Whereas the AP reported that elephants had been dying after consuming plastic trash on the websites, it’s not the plastic itself, primarily polythene, says veterinary surgeon Tharaka Prasad, the present director of well being on the DWC.
“A variety of elephants die every year on these rubbish websites, however the purpose of their dying will not be the polythene indigestion, however meals poisoning,” Prasad instructed Mongabay. “A number of meals waste is carelessly discarded. This waste is usually tightly sealed inside polythene baggage. When the meals goes unhealthy contained in the oxygenless atmosphere, the micro organism can create poisonous substances and we regularly discovered this the precise purpose behind the deaths of garbage-eating elephants.”
Ruminants like cows have a number of chambers of their digestive system that can lead to the buildup of polythene of their intestine, which may in the end be deadly. However an elephant’s digestive system is way easier, and the polythene passes by when the animal defecates. However the plastic isn’t with out its dangers, as it could typically lead to constipation, Prasad stated.
‘Brief-sighted determination’
In Sri Lanka, municipal waste is usually disposed of in open rubbish dumps by native authorities authorities. As a result of these websites are unhygienic and foul-smelling, native planners attempt to find them in areas away from human settlements. This leads to dump websites being established in areas frequented by wildlife, together with elephants.
“If we maintain the rubbish we generate within the city and semi-urban areas the place rubbish is generated in giant portions, the query of elephants consuming rubbish or elephants visiting rubbish dumps for fodder might not come up,” Sumith Pilapitiya, former director-general of the DWC, instructed Mongabay. “Rubbish must be disposed of within the areas the place it’s generated and never close to nature reserves or areas acknowledged as habitats for wild animals.”
Pilapitiya stated that in his time on the DWC, the division typically objected to new dump websites being arrange in and close to conservation areas, however was typically ignored. He recalled the choice over the place to dump waste from Dambulla, a city in Central province, the place municipal planners had narrowed down two potential websites: one in a forest reserve in Digampathana, and the opposite on the Dambulla-Matale highway, a vacant website however dotted with human settlements. Regardless of the DWC’s objections, the planners determined to arrange the dump at Digampathana. Right now, about 30 elephants frequently forage among the many trash there.
The choice additionally created extra bills for native authorities, who’ve needed to arrange an electrical fence across the website to maintain the elephants out and shield staff and tools.
“A really short-sighted, politically motivated determination resulted in making a contemporary downside with elephants in Digampathana with extra bills having to be borne to assist that unhealthy determination for electrical fences,” Pilapitiya instructed Mongabay. “The very best and the most affordable resolution is to keep away from creating new issues in atmosphere administration.”
Eat trash or raid crops
It’s extraordinarily uncommon for elephants to die whereas feeding at a rubbish dump, says elephant biologist Prithiviraj Fernando of the Centre for Conservation and Analysis (CCRSL).
Fernando, a worldwide authority on the species, who serves on the IUCN’s Asian Elephant Specialist Group, stated elephants feed very selectively at rubbish dumps. “In case you examine the well being standing (physique situation) of elephants on the rubbish dumps with those discovered within the parks in the identical space, those on the rubbish dumps are in a lot better situation,” he instructed Mongabay. Wanting finding these websites away from elephant habitat, the most effective factor to do is to kind the rubbish, so the elephants can feed on the natural waste individually, he stated.
Fernando and colleagues have studied elephant conduct at a number of dumps in southern Sri Lanka. They discovered the Uddakandara rubbish dump, situated close to Yala Nationwide Park, is frequented by 26 elephants, and the one in Wellawaya in has round 24 elephants. The workforce additionally monitored the now-defunct dump in Kataragama, the place greater than 45 elephants used to feed. They calculated that with a median of 20 elephants feeding at 54 dump websites all through Sri Lanka, that provides a inhabitants of about 1,000 garbage-eating elephants.
The research additionally discovered that the majority the elephants visiting rubbish dumps are bull elephants. Most of them have gunshot wounds, the tell-tale signal of a crop-raiding animal that has been shot at by farmers. This complicates the query of easy methods to preserve elephants out of dump websites with out driving them again into farmers’ fields.
“In case you shut these dumps, then these elephants will spend the time they’re spending on the dump on crop raiding, so it’ll dramatically enhance human-elephant battle leading to extra deaths — of individuals and elephants,” Fernando stated.
He cited the Uddakandara and Kataragama websites as textbook examples of what can occur in such instances. The federal government shut down the Uddakandara dump to cease the elephants from foraging within the trash. The elephants duly returned to raiding crops, prompting protests by villagers. Confronted with this strain, authorities reopened the dump website and the elephants returned to consuming rubbish. It was the identical story in Kataragama, Fernando stated, besides the location stays shut.
“The Kataragama dump was closed, and after that, the human-elephant battle within the space dramatically elevated, along with a rise in crop raiding,” he stated. “Folks have to speculate extra in placing up electrical fences to safeguard their crops and homes, and each elephants and individuals are getting killed.”
Fernando added that, “In a approach, these dumps really scale back direct human-elephant battle. However these dumps should be higher managed.”
