The best trees at an age of 300 years may have a diameter of 100 cm and more (Jamnicky, 1964). A diameter of 60 cm at breast height is common in 200 to 250 years old P. sibirica (Hempel and Jung, 1968). Two-hundred- year-old P. cembra trees may reach 40 cm and more (Figala, 1927; Gregori 1887), and selected trees of Swiss stone pine in Austria reach the same dimensions as P. sibirica trees (Holzer, 1969). Similar dimensions may be found in P. peuce too (Nedjalkov, 1963). The crown form of these species in general is narrow with small branches except that in open stands--above timberline especially—very often we find individuals with heavy branches, multi-forked trunks, and sometimes with candelabrum branches or a spherical crown.
