Conservation and resource stewardship in northern systems requires a…
Conservation and resource stewardship in northern systems requires a shift away from typical landscape ecology patch-corridor-matrix models, with their focus on connectivity and intactness as a surrogate for ecological integrity, toward models and methods more fitting for understanding the ecological status and trends of expansive, relatively pristine, and protected natural areas that are undergoing rapid (adjective-ecological?) change.

What are the limits of ‘Resilience’ as a goal?
The theory of resilience behind much of Conservation Biology and Landscape Ecology assumes much slower and lower magnitude rates of change than we are facing w/ climate impacts in northern systems (shifting to non-analogue climate systems and large-scale revision of driving landscape process dynamics). If the rate of change is fast enough and of such magnitude that once you land in one cup you are already set to bounce toward next one, then seems you are past the limits were resilience remains a relevant, hence feasible, goal or endpoint.
transition of state, not just magnitude
rapid, large-scale changes in landform processes, and their subsequent impacts on habitats and human communities
Increasing frequency to episodic events (storm surges, etc.)
Increasing exposure to episodic events (lack of ice cover, permafrost thaw, reduced snow season, etc.)
Non-point source pollution (broadscale pollution fallout; mercury release from permafrost?, etc.)
-
Internal
Socio-economic
Large potential for development-driven change - infrastructure development, land conversion; (map of lease sales and development permitting)
increasing frequency of episodic human-mediated disturbances of traditional activities (aircraft noise, etc., etc.)
Institutional
Institutional issues stemming from assumption of ‘intactness’ - poor job actually tracking and mapping where things have or are happening on ground, less effective record keeping that may prevent use of common landscape ecology models.
Effective identification, estimation, and consideration of cumulative effects
-
Intellectual
Existing impacts not accounted for in standard metrics of intactness - e.g., impacts of indigenous communities, loss of spp already occurred, etc.
Need consistent land management strategy for Intact systems (unlike more developed areas, which have been the focus of such efforts).

Fundamental contrast in dominant stressors in northern system versus those that have been the focus of most landscape ecology. #
