CLIMATE RESPONSE FUNCTION ANALYSIS OF ABIES PINDROW (ROYLE) SPACH. PRELIMINARY RESULTS
MOINUDDIN AHMED, NASRULLAH KHAN AND MUHAMMAD WAHAB
Abstract: Abies pindrow was used for Dendroclimatic investigation from Ayubia, moist temperate and from Astore, dry temperate area of Himalayan region of Pakistan. Trees of this species not only cross-matched in a particular site but despite belonging to two different climatic zones good cross-dating was achieved between two sites. Dated chronologics from 1500-2000AD and 1680-2000AD was presented from Astore and Ayubia respectively. Response function analysis was used to investigate climate and growth response of trees from both sites. It is shown that overall analysis was highly significant and variance due to climate was 15% to 25%. It is suggested that long term climatic variation or trend could be detected by this species, however more investigation should be carried out, increasing sample size.
