Background
Sri Lanka Has been Famous as a tourist location since ancient time. Named the “Pearl of the Indian Ocean”. It has been visited written about and acclaimed in many ancient chronicles. Being close to the equator, it has a year – round sunny weather and with its topography it harbors a host of rich biodiversity promoting ecotourism. With a costal belt right round the island it has attract many visitors to its beaches. The ancient history and monuments have called in tourist to its cultural sites.
Currently, after the advent of the terrorist conflict, new vistas have opened up in the tourism trade. These are popularly known as a ‘Eco Tourism’, ‘Nature Tourism’ , ‘Adventure tourism’, ‘ Ayurvedic tourism’, ‘Religious  tourism’, ‘Agriculture tourism’, ‘Cave tourism’, Culture tourism’,ect
Palaeo biodiversity is the biodiversity of ancient times. It addresses ancient man and his interaction with his palaeo environment. It Speak of the geological eras, the prehistoric people. Therefore, this subject has another aspect of interest to the visitor. With the prehistory that dates far back as  125000 BP and its locations situated amidst forests and streams it mainly attracts the ecotourism.
Since this subject has been introduced newly it is not possible to market this product alone. Therefore it is much more convenient to market it along with other product such as ecotourism, nature tourism, adventure tourism and cave tourism.
Batadombalena rock shelter is one such location which can be developed as a polio tourism site. It is situated 2.5 hours from Colombo near Ekneligoda.

Previous excavations
Batabombalena first excavation by P.E.P.Deraniyagala in 1938.The finds included fragmentary human remains and stone artifacts. The excavation was of 4 feet and deraniyagala assigned the assemblage of stone artifacts, in particular the association of microliths and human remains, to the Balangoda phase.
A preliminary examination was made by Dr.S.U.Deraniyagala in 1979 which revealed a rich occupational deposit.Thereafter,an excavation of 2.6 m was conducted.
The stratigraphic sequence of seven main occupational layers and 3 underlying strata directly above bed rock has been described by Daraniyagala in 1982.
Layers 1 – 3 from top downwards were considered to have been described in resent time by the extraction of guano fertilizer for village paddy fields, and leaving of the floor by monks who used to live in the rock shelter. The occupational deposited in layer 4 was described as a massive homogenous stratum with brownish sand and silt containing stone artifacts and faunal remains. Layers 5 and 6 were considered to be the site’s major occupational layer 7 contains many stone artifacts including geometric microliths which were radiocarbon dated to approx 30 000 years BP

Informal Activites of Tunnal(Dona)’Gem Pit,Tend To Decsend Natural lands of Sabaragamuwa Basin Within Next Twenty Year

Informal Activites of Tunnal(Dona)’Gem Pit,Tend To Decsend Natural lands of Sabaragamuwa Basin Within Next  Twenty Year

                                               Mr.Aravinda Ravibhanu Sumanarathna


Sabaragamuwa is a unique province which consisted special special geological background. Pleistocene fossil deposit & gem trade are most plansible factors for exhibit traits of sabaragamuwa.Rathnapura is the center operation station of Gem trade.Eheliyagoda,Kuruwita,Rathnapura,Pelmadulla are the majority cities which consisted huge gem pits.Business society of Sabaragamu area is getting high currency and economy from Mine Industry,but because of its disorganized activities it’s becoming a threat to the Natural land and Bio diversity. In Sabaragamu basin (0m-6m) high land has become corrosion .Many mines and disorganized Dona mines can be identify
Fig 01:Gem Pit(Dona) In Sabaragamu Basin
Many mine industry courses 100m of diameterand 60m deep major pits have sap and examine the lode . Therefore soil profile made as a vertex and inconstancy land has got created. Though these pits filled with soil back ,during the rainy days it will turn in to marshy land.For a year Sabaragamu area gets  highest precipitation, therefore eventually  land will get destroyed.Because of disorganize activated dona mines main cities of sabaragamu districtthreat to be sink.most of the dona pits are 10m-150m deep and 150 dona’s are there in palmadulla city. 40% of dona mines 40m-100m depth goes through the city. Therefor in different levels of donas goesdown  through the space enclosed soil will sunk down.In 20 years 80% of palmadulla city ,10 % of rathnapura city and 40 % of around the city ,60% of kuruwita city , 10% of Ehaliyagoda city  and 30% of around the city will be in danger  to sink. We would like to discuss the data’s that based  on  land scape in this area have found its sinking  briskly and cusses including natural and activities that has been taken  during 2005 -2015.
