III.  RESULTS  AND  DISCUSSIONS A.  Climate  conditions The  climate  trend  between  2009-2011  and  2014-April  2016  was  shown  in  Fig.1.  During  these  periods  two  El  Niño  events  were  observed.  NOAA  8  reported  that  the  El  Niño  occurred  since  July  2009  to  May  2010  and  February  2015-the  present  (April  2016),  consistent  with  the  observed  drought  at  the  study  forest  site.  The  maximum  temperatures  during  the  study  period  were  39.6,  40.6  and  41.7oC  in  2010,  2015  and  2016  in  April  and  these  were  37.0  and  36.3oC  in  2009,  2011  in  March. During  the  dry  season  (November  to  April  of  the  following  year),  long  drought  was  found  due  to  less  rainfall  (<5  mm)  for  whole  season  during  2009-2010  and  2015-2016.  The  sums  of  rainfall  were  59.10+9.83  and  71.40 +9.22  mm,  respectively.  These  ere  240.70  55.51  and  279.40+37.32  mm  during  2010- 2011  and  2014-2015,  respectively  (rainfall  in  normal  year  was  significant  higher  than  El  Niño  year,  p<0.02).  Fig.1  Climate  conditions  a)  monthly  air  temperature  consisted  of  maximum  air  temperature  (Tmax),  mean  temperature  (Tmean),  minimum  temperature  (Tmin)  and  monthly  rainfall  b)  monthly  soil  moisture  and  soil  temperature 306 Proceedings  of  the  International  Conference  on  Climate  Change,  Biodiversity  and  Ecosystem  Services  for  the Sustainable  Development  Goals  (SDGs):  Policy  and  Practice  27-29  June  2016,  Cha-am,  Phetchaburi,  Thailand
