Thousands of years old ‘near fossilized’ animal remains found in Yala

October 7, 2016

Bone fragments believed to be animals that died thousands of years ago were discovered from a rock pool in Yala this week.

They are parts of skeletons of elephants, tortoises, wild buffaloes, spotted deer, wild boar and other animals, say students of the Kelaniya University Postgraduate Institute of Archaeology who are studying the fossils.

The level of fossilisation indicates the animal bones are 1,000 to 5,000 years old, palaeobiodiversity expert Kelum Manamendra-arachchie said.

“Some of these bones could be older,” he added. With time, the organic materials inside bones are replaced by mineral substances and experts can estimate their age by observing the extent of this fossilisation process.

Fossilisation only happens in rare cases. Animal carcasses are usually eaten or bacteria can rots them away before fossilisation can occur.

Fossils are found when animals die in location where their carcasses – or parts of it – are protected from scavengers and the elements, such as when they are found on the seabed or a river bed and become buried in sand, soil or mud. Rock pools with beds of clayey mud are ideal, Mr. Manamendra-arachchie pointed out.

The bones were found during efforts to find water sources for thirsty animals. Due to the drought, many of the Yala National Park’s waterholes have run dry. The Department of Wildlife Conservation (DWC) sent a crew with a backhoe to deepen a rock pool known as Wel-mal-kema in Yala Block I.

These rockpools are the lifeline of wild animals during droughts as many of them have water when other water sources run dry. It is believed animals became trapped in the mud of this rock pool when they came there for drinking water thousands of years ago.

Through analysis of the bones, Mr. Manamendra-arachchie is able to surmise that wild buffaloes were plentiful thousands of years ago in Yala. The national park has a population of wild buffaloes but these are mixed with domesticated buffaloes. Mr. Manamendra-arachchie says the base of the hobes are thicker in wild buffaloes and there were many such skulls among the excavated bones.

This Wel-mal-kema is 30 feet long and believed to be 30 ft deep. Only half of it has been excavated and it is possible that there could be much older fossils.

Yala has a number of such rock pools, so there could be many mysteries waiting to be unearthed. The Director-General of the DWC and the Minister for Wildlife has requested the Institute of Archaeology to continue with this study in Yala.

Mr. Manamendra-arachchie said he analysed a similar, but smaller rock pool in 2005 in Thanamalwila from which he collected four truckloads of bones that, he believes clearly accounted for more than 100 elephants, 150 wild buffaloes, 200 spotted deer, 150 wild boar and 50 sambhur deer. Most of them had almost become fossilised.

Gemunu & the Soldier: Images of Yala Shooting incident

August 20, 2013

The real story behind the shooting incident in Yala is now fully revealed. The images of the incident has been posted on “Sri Lankan Wildlife” group by biologist Manory Gunawardane. She stresses  that the incident should be taken to rethink on issues Yala National Park faces due to over-visitation. I’m re-posting this series of images on my blog for future references..

President Orders the camp sites to be out of National Parks

October 21, 2012

Private campsites at national parks are to be dismantled and removed, on an order from President Mahinda Rajapaksa. The order came at a special Hambanthota District Development Committee meeting held last week, at which a report was tabled that claimed these campsites had become permanent and were polluting the environment.

Environment lawyer Jagath Gunasekara said he welcomed the news, as the private campsites were illegal. Under the Fauna and Flora Ordinance, only the Department of Wildlife Conservation may provide facilities inside a park. The lawyer said private parties had no right to clear vegetation, build roads or put up structures inside a national park.

These private campsites have been maintained for years inside national parks with permission from Department of Wildlife Conservation. It was only when a dispute arose between campsite operators and Yala Jeep drivers that the illegality of these structures has come to the spotlight. In August, a gang of Jeep drivers assaulted employees of campsite operators, saying they were taking away their business. Campsite operators denied the allegation, saying their services were pre-booked several months ahead, while Jeep drivers conducted safaris on a daily basis. Reports also say that over 100 jeep drivers gathered at Palatupana near Yala entrance with aim of beating the leaving campsite operators and there is lack of Police Protection. However, jeep drivers too break law and discipline inside the park driving vehicles on high speed. 

[Full text: It is reported that the President Mahinda Rajapakse has ordered private campsites to be removed from the National Parks. As state mediate reported, he made this directive addressing a special Hambanthota District Development Committee meeting last week. According to the report, President Rajapaksa said these camp sites have now become permanent camp sites and the environment of the National Park has been polluted in alarming proportions according to information he gathered.

Environmentalists commend the move of the Rajapaksa also pointing out that the private camp sites are also a violation of law. The Environmental Lawyer Jagath Gunasekara says that he welcomes this move as the private campsites are clear violation of law. He points out that according to the Fauna and Flora Ordinance (FFPO) only Department of Wildlife Conservation (DWC) can provide facilities inside the park. Furthermore no person can engage in having business in National Parks. The veteran lawyer point out it is also illegal to clear any vegetation, construct roads or erect any structures inside a National Park by private parties.

However, these campsites are been operated for many years and only a raw between the campsite operators and Yala Jeep Drivers had taken this issue to the arena. In august, several employees of camp site operators have been beaten savagely by the Jeep drivers saying that they are grabbing the jeep drivers business in unfair manner. But the campsite operators denied these allegations saying that their services were pre-booked several months ahead while Jeep Drivers are getting their safaris on daily basis.

This raw has been later settled down, but followed a DWC team to inspect the sites. They had given green light for 2 of the camp sites, but the one operated by the EcoTeam was temporary closed down as the conditions were found unsatisfactory. The head of the Leopard Safar; Noel Rodrigo said their operation is clean and done on Environmental Friendly manner with limited environmental footprint.

However, organizing a press conference on the issue; Sajeewa Chamikara of Environmental Conservation Trust alleged that 4 more private companies are given campsites in Yala. It is also revealed that those private campsites are going to be allowed in other National Parks too which could be a dangerous precedence.

Rukshan Jayawardane who is another activist who follows the Yala issue also welcome the president’s decision. However he pointed out that there should be a thorough investigation on how these private campsites have got permission through DWC and allowed to be running for many years ignoring the FFPO. Rukshan also point out that the visitor misbehavior and Tissa Jeep Drivers activities too should be regulated and monitored properly in Yala National park. The Jeep Drivers are speeding in the national park and on busy long weekends the Yala National park is getting lots of vehicles that all in search of leopards which ends up speeding.]
