The present study reveal some startling facts on the same line while making an intensive study about plant biodiversity of Gorkha hills also called Itchagarh hills during 2005-2009. This is the second highest hill of Jharkhand after the Parasnath, and its height is about 1310 m.(about 3900 ft.)
The average temperature of the hill top area was about 270 C TO 300 C in the month of June and July in the year 2007,2008 and 2009. How ever it was a bit cooler i.e. below 23o C in the same months in the year 2005 and 2006. It was observed that the distribution and richness of thermophobic medicinal plants has been adversely affected at the height of 2500 ft. and above due to increase in temperature. It was a great loss recorded in biodiversity of that area and ultimately the natural resources . The plants like Thalictrum foliolosum and Rubia manjith are thermophobic and can hardly tolerate the increase in temperature (18-220 C in the month of January) at the height of 2500 ft. and above. Their flowering period has now shifted from July – August to January and October to January respectively during 2007 -2009. Click for pictures and medicinal uses–
Timely eradication of newly introduced thermophilic plants and checking of deforestation may help the population of thermophobic plants for its survival.
