PROTECTION OF THE NATURAL ENVIRONEMENT
For many destinations, the natural environment is one of the primary attractions for leisure visitors. A wide range of recreational, activity based, educational, cultural activities and experiences, can be accessed by visitors in natural and protected areas. The development of natural and/or protected areas for tourism requires a careful balance between providing adequate visitor experiences and services, protecting the ecological and cultural values of the area and ensuring the long-term sustainability of the site.

Cave Formations
Cave formations are created when acid reacts with limestone or a rock containing 80% or more calcium carbonate. These formations are found on the walls, ceilings and floors of caves. Cave formations are called speleothems, from the Greek word "spelaion",cave and "thema" meaning deposit (Robertson, 2004). A number of conditions need to be present for speleothems to form within a karst enviornment. First the types of rocks within and surrounding the cave need to have an 80% content of calcium carbonate which is usually limestone, dolomite or a similar type of rock. The bedrock also needs to be highly fractured or jointed so the water can flow through or follow these joints or fractures. The bedrock also needs to be relatively close or at the surface. The fourth requirement for Karst and spelethem formation is a relatively moderate annual rainfall (>500 mm). The final requirement to form the speleothems is vegetation cover. Vegetation enhances the Karst process by producing more available acids. A few variable factors including humidity, temperature and air flow through the cave also play an important role inspeleothem formation.

Just one drop of water on the ceiling of a cave is all that is needed for a stalactite to start forming. Each drop contains a small amount of dissolved limestone that has been acquired from flowing through the cracks and joints of the bedrock. Once this drop is hanging suspended from the ceiling some of the contained carbon dioxide escapes the droplet. Due to this carbon dioxide escaping, the droplet can’t hold as much limestone so a thin external ring is formed. After the drop falls, a small layer is left as a residual. After multiple drops have fallen the drip stone forms a hollow stalactite. These stalactites are called soda straws. As growth continues the soda straw regularly becomes plugged by the deposition. The limestone rich droplets are now forced outside of the soda straw creating the droplets to leave a small “paper trail” of limestone. This results in the cone shaped drip stone. Average growth rates for drip stones (stalactites) are about ½ inch for every 100 years (Figure 2a and 2b). When multiple soda straws or drip stones join together a bacon strip is formed. These features usually form along a joint where multiple drip stones and stalactites can form.
