ENTS, I found this article on the highest treeline in the Northern Hemisphere:
http://www.bioone.org/doi/pdf/10.1659/mrd.0792?cookieSet=1 It seems to be the highest treeline in the world as well. The highest altitude trees are Juniperus tibetica at 4900 m (=16,000 ft) in southeast Tibet. Here tree is defined to be at least 3 metres (10 ft) tall. The article mentions 6 metres (20 ft) tall Juniperus indica at 4650 m (15,300 ft) in Bhutan. A treeline almost as high occurs in Bolivia: http://www3.interscience.wiley.com/cgi-bin/fulltext/118697038/PDFSTART There, Polylepis tarapacana grows at least 3 metres tall up to 4810 m (15,800 ft). - Kouta -- Eastern Native Tree Society http://www.nativetreesociety.org Send email to [email protected] Visit this group at http://groups.google.com/group/entstrees?hl=en To unsubscribe send email to [email protected]
