Biological diversity in Madagascar the island known , 90% are endemic species , of which this piece of green area of 1550 square kilometers of national parks and protected areas itself like a solitary Island , or some kind of eco- fortress . It is rugged terrain , inaccessible , a huge limestone peaks – local call ” green barbarians “- throughout the entire territory , making the area almost no one can pass through . In Malagasy , the ” young barbarians , ” the term means ” the place can not go barefoot , “but we found that , in order to walk in here , even wear sturdy shoes is not enough .
This peculiar structure is a karst limestone a , dissolved by the water erosion forming . Rock carving out such a complex and rare appearance of the process , in Madagascar, with very few outside the region were similar . Researchers believe that the huge limestone groundwater infiltration beds, fractures and faults occur along the dissolution of erosion , forming caves and tunnels. Hole cavity increases, eventually leading to crack the top along the previous collapse to form a straight valley , called ” Rock Valley ” , depth up to 120 meters , stands on both sides of spire -like Yanfeng . Some hard rock groove narrow to humans walking through the streets while others are so wide .
Observation of young pilots from the air when the barbarians , often associated with deep urban canyons of Manhattan , the sky line inserted into the irregular streets , buildings and parks grid, further down is one from the pipes, drains and underground tunnels Composition of the circulatory system . The biological than Yudui Qing Yi in the same application , because the structure looks much like the rock -lined high-rise apartment , each layer provides for a range of different species inhabit the community. In the highest places , the soil is very thin , there is no sunlight can avoid the shade , sun exposure temperature to rise to 32 degrees Celsius under , only drought-tolerant plants and can come and go freely between the pinnacle and the canyon ‘s Animals can survive in this .
Even if other parts of Madagascar, the ecosystem is already falling apart , this city within the walls has been sheltered lives . Scientists call it the “ideal haven . ” Biology of the “sanctuary “concept refers to a similar safety zone camps , habitat reduction , the bio will be relegated to one . Once shelter animals and plants living in seclusion , the difference between their relatives will become more and more . Madagascar is itself a microcosm of this process , the island ‘s many species of very strange , and they are located far from the relatives of the African continent .
Tsing Yi as remote and difficult to cross , its limited impact on human development , but is more likely regional climate change threat . Lower humidity , less rainfall , rainwater acidity increased , these changes in any one of a forest or even Yanfeng itself may cause harm . “I want to know how long left the forest survive , ” Brian – Fisher said , “may soon disappear . This is a barrier , but extremely fragile . and in fact we know very little of the It has only just begun to understand . ”
