The fundamental influence of landscape structure on boreal forest dynamics, northern Sweden

Presented by Ms. Sarah SCOTT on 15 May 2013 from 18:00 to 21:00
Type: Poster Presentation
Board #: 19

Content

We examined the influence of landscape structure on disturbance, succession, and the duration of legacies initiated by fire across a naturally fragmented boreal forest in northern Sweden. We inventoried 2,038 trees, of which 1,249 were cored and dated, and collected 128 soil samples on 16 distinct forested islands. Several stand characteristics were significantly correlated with island size, including density (r = -0.77), basal area increment (r = 0.7), the importance of Betula (r = -0.63), and the importance of Picea (r = 0.69). Soil charcoal was found in 76 of 128 samples and on all but one island. Charcoal mass showed no consistent relationship with island area, isolation, or any stand variables. Carbon dates are forthcoming. Our findings indicate landscape structure as a fundamentally important driver of forest structure in this landscape and provide a frame for understanding the length of fire’s ecological legacy in boreal forests.
