Fundamental Influence of Landscape Pattern on Boreal Forest Dynamics
The structure and composition of forests around the world are changing in rapid and unprecedented ways. Human activities, such as logging and expansion of the urban-wildland interface, have resulted in highly fragmented landscapes in areas that were once covered with relatively continuous tracts of forest. The close links between landscape structure, disturbance regimes, and successional processes suggest that modern fragmented landscapes are likely operating outside of their historical ranges of variability, yet the long time scales on which the dynamics of forest communities operate make this difficult to assess. Additionally, landscape structure, legacy effects, and seed source availability and proximity also represent important determinants of vegetation change. Understanding how forest communities will change in the future is key information needed in the development of long-term management plans for these ecologically and economically critical systems. This project is using the naturally fragmented landscape of Granlandet Reserve in northern Sweden as an analog to explore the long-term and unintended consequences of changing landscape structure.
