POPULASI ANGGREK ENDEMIK Tainia elongata J.J.Sm DI KAWASAN TAMAN WISATA ALAM SITU GUNUNG, SUKABUMI

Abstrak

Tainia elongata is one of several endemic orchids found in Java. This terrestrial orchid grows in the mountainous forests of Java up to 1,400 meters above sea level. Its wild population is still largely unknown. The Situ Gunung Nature Tourism Park area is a natural tropical rainforest mountain ecosystem with a diversity of protected flora and fauna. Data collection on the Tainia elongata J.J.Sm orchid population and supporting data was carried out using the line transect method and sample plots by dividing it into 3 locations, namely location A at an altitude of 1024 - 1027 m asl, location B at an altitude of 1031 - 1036 m asl, and location C at an altitude of 1042 - 1166 m asl. From the 3 sampling locations, 23 individuals of Tainia elongata, J.J.Sm. orchids were found. At location A, with a population value of 0.002/m2, 75% humidity, air temperature of 220C, soil pH of 6.9, the few individuals found were influenced by the dominance of ferns. Location B had 73% humidity, an air temperature of 220C, soil pH of 7, and no orchids were found due to high human activity. The third data collection location is location C with a population of Tainia elongata orchids, J.J.Sm 0.024/m2 with an air temperature of 210 C, humidity of 80%, and soil pH of 6.9. The high humidity at location C resulted in the large number of individuals found, and the orchid habitat at this location is still maintained.
