Resilience: Definition
The capacity for renewal in a dynamic environment
- Gunderson 2000
Highly Vulnerable
Limited capacity to adapt
Disrupted function, low diversity
Highly Resilient
Large capacity to adapt
Sustain function and diversity
Resilient site: Has characteristics that maintain ecological functions and will likely
sustain a diversity of species even as the composition and ecological processes
change.
Vulnerable site: A place where processes are disrupted and fragmented, and
diversity is likely to decrease. The site may still perform many natural services
Central Concept
By mapping key geophysical features and
evaluating all occurrences of these
features for characteristics that buffer
against climate effects, we can identify
representative examples of geophysical
features that are most resilient to climate
change.
Premise # 1
Geophysical features underlie the spatial
distribution of biodiversity and a region’s
biological richness is due, in part, to this
geophysical diversity.
Diversity and Land Facets
The higher the number of land
facets the higher the number
of species

Land Facet Development
Three geophysical factors and breaks were used to create land facets.

along with a description of how they were defined)

Premise # 2
Geophysical features underlie the spatial
distribution of biodiversity and a region’s
biological richness is due, in part, to this
geophysical diversity.
Topoclimate diversity and local permeability
convey a level of resilience to a landscape
or site.
Topoclimate Diversity
Landforms control the distribution of moisture, nutrients and
climatic effects.
N
More Heterogeneity =
more options for
species to move and
rearrange at a given
site.

Use in Conservation Planning
•
Assess existing conservation sites for terrestrial
resilience.
Ecoregional Assessments
Portfolio sites intersected
and ranked by proportion
of Resilient Land Facets
Use in Conservation Planning
•
•
Assess conservation status of resilient land facets in
existing conservation portfolios.
Use Resilience to update ecoregional assessments
