Spatial and temporal variability in forest growth in the Olympic Mountains, Washington: Sensitivity to climatic variability
Holman, M.L., and D.L. Peterson. 2006. Spatial and temporal variability in forest growth in the Olympic Mountains, Washington: Sensitivity to climatic variability. Canadian Journal of Forest Resources 36:92-104.
We compared annual basal area increment (BAI) at different spatial scales among all size classes and species at diverse locations in the wet western and dry northeastern Olympic Mountains. Weak growth correlations at small spatial scales (average R = 0.084-0.406) suggest that trees are responding to local growth conditions. However, significant positive
growth correlations between geographically adjacent forest types (R = 0.440-0.852) and between watersheds (R = 0.430) indicate that there is a common overarching growth-limiting factor (e.g., climate) that affects tree growth over large areas.
