Introduction 1. 1 Eco-tourism Tourism based on the natural ecological features of the area as opposed to manufactured attractions or features like old forts and structures is referred to as ecotourism. This nature tourism promotes conservation and supports sustainable development. Environmentally responsible travel and visitation to relatively undisturbed natural areas, in order to enjoy, study and appreciate nature and any accompanying cultural features that promote conservation, have a negative visitation impact and provide for substantial beneficial active socioeconomic involvement of local populations. Under the right circumstances, ecotourism has proven to be one of the most effective means to finance biodiversity conservation. In most rich biodiversity areas, actual revenue flows for ecotourism are better than non-timber forest products and biopharmacy, and comparable only to agroforestry. Because the dominating land use in protected areas and buffer zones is agriculture and forestry, ecotourism is an opportunity for the creation of additional income to farmers / foresters and to generate financial means for the management of protected areas, especially where governmental park management agencies have little resources. 1. 2 Agrotourism and Agro-ecotourism : The symbiotic relationship between tourism and agriculture that can be found in agrotourism (i. e. holidays on farmland) is a key element of an environmentally and socially responsible tourism in rural areas. Rural hospitality offers new employment and income generating opportunities for rural populations, including agrotourism as expression and cultural exchange of agricultural practices, artistic heritage and craftsmanship and culinary traditions. Agrotourism may take several forms: holiday farms, farmhouse bed-and-breakfast, farm camping, mountain resorts, equestrian centres and other forms of rural accommodations. Such facilities are an innovative payment system for environmental services generated on and around agricultural lands While ecotourism is nature-based and agrotourism is farm-based, agro-ecotourism is a combination of both. The rural landscape, usually a combination of wild and agro-ecosystems, is the most important resource for tourism development. It is obvious that a diversified agricultural landscape, with semi-natural habitats, has a greater aesthetic and recreational potential over uniform, degraded and/or polluted agricultural areas. In Europe, agri-environmental policies often promoted organic agricultural activities as a most effective means for landscape conservation: for example, the European Union Life Environment project run by the French Federation of Parks and Reserves adopted extensive animal husbandry to prevent the negative impacts of unmanaged forests on some botanical meadow species and to promote a landscape quality attractive to tourists. Examples from the Alpine Region showed that agriculture (e. g. in Carinthia, Austria) maintained an ecological value much more attractive to tourists than areas where agriculture activities were extremely reduced. Tropical countries that harbour extraordinary biodiversity have an untapped potential for generating tourism business around biodiversity-rich farms. For example, shade cacao and coffee farms have a higher biodiversity than forest habitats: families could receive money for visitors access to their land for bird-watching or could be actively involved in the agro-ecotour. Agro-ecotourism in certain locations provides a strong economic incentive to small farmers to commit to biodiversity-friendly agriculture management. 2.

Methodology: A survey was conducted in the proposed land between 28th December 2006 and 15th January 2007 in order to evaluate the potential of the proposed land for ecotourism. A team of specialists in the fields of forestry, flora, fauna and geology participated in the survey. 4. Findings of the study 4. 1 Location and access: The proposed land can be accessed from Balangoda via Kaltota, Meddabedda and from Beragala junction via Tiriwanagama. The proposed land is located in the Badulla districts. 4. 2 Climate and soil: The proposed land falls in the mid country intermediate zone of Sri Lanka, more specifically its within the IM2b agro-ecological region. The 75% annual rainfall expectancy of the area is over 1600 mm (Agro-ecological map of Sri Lanka, 2003). The elevation is approximately 200-300m above mean sea level. The rainfall distribution of the area is such that mid January to February and June to Mid September is dry, while other months of the year are wet. The study area has a very steep, hilly and rolling terrain. Table 1. Dry / wet months Dadayampola. MonthMAMJJASONDJF Wet / dry monthsWWW DDDD/WWWWW/DD Cropping season**********ââ¬â The soils of the study area is consists of Reddish Brown Latosolic, Immature Brown Loam, Red Yellow Podzolics and Low Humic Gley in the low lying areas. The physical characteristics of these soils are moderate to deep, well drained and relatively less susceptible for soil erosion. 4. 3 Land Use: Land use in the proposed land is shown in the Table 1. This shows that most of the land is covered with natural vegetation. This natural vegetation, uneven topography and natural streams that flowing through and bordering the land have given rise to diverse range of habitats and eco-units. These landscape characters have made this proposed land having so much of biodiversity and visual amenity. If developed properly this land could be made into a paradise for eco-tourists. The wealth of biodiversity recorded in different land use is discussed in a different section. Table 1. Land use in the proposed land in the Dadayampola.

The site area is accessible from Balangoda via Kaltota, Medabedda and from Beragala junction via Thiriwanagama (Map 1-Location Map). Geological background of the site Geologically, this area belongs to Highland Complex and most high grade metamorphic rocks can be identified in and around the proposed project area. The rock types commonly found belongs to highland complex are, Garnet Sillimanite Gneiss, Quartzite, Marble, Calc gneiss, Charnockite etc. (Figure 2-Geology map). Apart from those highland complex rocks, there are some rocks which are belongs to Wanni complex, such as Pink granitoid gneiss, Pegmatitic granitoid gneiss and Hornblende Biotite gneiss. The area around proposed land is rich with very complex geological structures, among those, local thrusts, Synforms, antiforms, shear zones and lineaments are remarkable. As this area lies to the 2nd Peniplan (Witanage,1972) Northern direction to the study area, high cliffs and escarpments can be observed, which exists between 3rd and 2nd peniplan. Displacement of rock strata along faults, highly crushed (Mylonite) newly formed week rock layers, fault gouge and mobilized marble beds represent neo-tectonic movements of the area. As a result of this complex geological situation, gems and other precise mineral deposits can be expected in the surrounding area. But still those are not well identified and there are some deposits already known, i. e. Corundum, Tufa, Calcite, Feldspar (Fig. 2) Figure 1: Complex geological structures represent neo-tectonic activities of the area, foreign (dark) fragment embedded in local host rock Figure 2: Abandoned gem pit. That represent near by villages have discovered the availability of precise minerals in the area This complex geological setting is represented by the extremely complex rock strata orientations in the area. Dipping and strike of rock beds greatly vary in the vicinity. Within the proposed site area, impure and pure quartzites, Marble, Charnockitic gneiss, and Pink Granitoid gneiss rock beds are identifiable. Those rocks in the site are trending N70? W with the dipping vertically. One prominent joint system was observed as N10? E with vertical dipping. Stream network of the area is purely controlled by the geological structures. Figure 3: Highly jointed, vertical dipping Mable rock in the Kalkan Oya bed. Figure 4: Stream network of the area is completely controlled by the geological structures. Figure 5: The area is rich with geological structures and geomorphological features. The Ubmagala rock, from the proposed site Apart from geology, geomorphology is important for the effect of natural hazards in the area. Although the area is situated under the 3rd peniplane, there was no observations of previous occurrence of landslide activities. The area is covered with residual soil derived from parent rocks except closer to the stream. A strip of river bank (not always) is alluvial deposit, which was transported from the river. Therefore availability of precise gem minerals is high in this area. But this was not studied well yet. Distribution of slope is presented in the Map 3 (Slope map), and that clearly shows majority of slopes in proposed project area is less than 30 degree. This is very favorable for hazard free environment. Discussion / conclusion In the point of geological view, this area is a paradise for earth scientists. Undiscovered geological, mineralogical and structural geological features may give an advantage for a echo-tourism project with hazard free environment. Observed features related to neo-tectonic movements may need further study by earth scientists. According to the literature, concept of well un-proved symotogenic up-warping (Vithanage,1972) and availability of high precise gem minerals in the area can be explored with this proposed project. M.
