Tree Line, Sakha Republic, Russia - russ199 Additional Information Andy Bunn, Andrea Lloyd, and Logan Berner Purpose of Collection: The purpose of this collection was to characterize stand-level tree growth patterns for comparison with satellite-derived vegetation indices. Cores and cross-sections are stored at: Western Washington University, Bellingham, Washington, USA. Reference: Berner, L.B. 2010. Evaluation of high-latitude forest growth using satellite-derived vegetation indices. M.S. Thesis, Western Washington University. Available from WWU Masters Thesis Collection: http://content.wwu.edu/u?/theses,343. Notes: Samples were collected at approximately tree line near the mouth of the Kolyma River. Locally, this species is referred to as Larix cajanderi Mayr. The ITRDB uses the synonym Larix gmelinii (Rupr.) Kuzen.
