Agashashok White Spruce Branch Growth 2005-2008

Project:

ARCSS

Summary

This dataset includes retrospective measurements of white spruce branch extension growth (mm) made at breast height (4 measurements from each tree) during late August of 2008. Annual growth increments were identified using bud scars and measurements were made using digital calipers. The study includes 36 trees and 4 experimental treatments established in June of 2006 (i.e., n=9): control, fertilized, watered and fertilized x watered. Fertilized trees received 5 g N m-2 yr-1 applied as granular NH4NO3, 2 g P m-2 yr-1 applied as granular P2O5 and 4 g K m-2 yr-1 applied as granular K2O. The watering experiment was carried out using a passive throughfall displacement system that increased the size of each precipitation event (~2x). The study site is on a riverside terrace next to the Agashashok River, Noatak National Preserve, AK (67.477, -162.216). Coverage is from 2005-2008.
