Himalayan blue pine (Pinus wallichiana. A. B. Jacks. Syn. P. griffithii) is one of the important indigenous pines of Pakistan with a very large range of natural distribution. Collection of seed from authentic seed sources of blue pine throughout its natural range in Pakistan and Azad Kashmir was started in 1972 with the financial assistance of PL-480 Project of U.S. Department of Agriculture, for establishment of provenance studies of this species (Siddiqui, 1978). At the commencement of the project, information was lacking on the exact location, accessibility, flowering and fruiting time of blue pine stands in different parts of the country. Further, due to large extent of distribution, rugged terrain of blue pine forests and limited staff availability, it was not always possible to visit all localities in one year and collect cones at the time of their ripening. Attempts were therefore made to visit as many sites as possible for seed collection each year. A list of seed collecting localities in different forest divisions having blue pine forests in Pakistan and Azad Kashmir is given. The table shows that 41 seed collection areas were visited a number of times during the past 7 years at the time of seed ripening.
