Probable impact of global warming on plant biodiversity in the Itcha garh hill area of Jharkhand.


“Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner,” said Terry L. Root, a senior fellow with Stanford’s Institute for International Studies (IIS) and lead author of the Jan. 2 Nature study.
“Clearly, if such ecological changes are now being detected when the globe has warmed by an estimated average of only 1 degree F (0.6 C) over the past 100 years, then many more far-reaching effects on species and ecosystems will probably occur by 2100, when temperatures could increase as much as 11 F (6 C),” Root concluded.

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–

Conclusion :

Timely eradication of newly introduced thermophilic plants and checking of deforestation may help the population of thermophobic plants for its survival.
