Ecological RestorationEcological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged or destroyed. SER (2002)
“The role of the practitioner is to i iti t t d l t ”reinitiate ecosystem development.”
Clewell & Aronson (2007)Restoration is not a singular event
Ecological RestorationEcological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged or destroyed. SER (2002)
“An ecosystem has a developmental trajectory… This trajectory can be predicted into the futureThis trajectory can be predicted into the future… The accuracy of that prediction depends upon: the environment & random events” Clewell & Aronson
(2007)

Time“An ecosystem has a developmental trajectory… This trajectory can be predicted into the future… The accuracy of that prediction depends upon: the environment & random events”
Clewell & Aronson (2007)
Trajectory Endpoints: What is “recovery”?In a restoration there is maximum recovery of ecosystem
structure and functions
Bradshaw (1987)
Trajectory Endpoints:
How do we determine the desired endpoint ?

Ecological RestorationEcological restoration is the process of assisting the recovery of an ecosystem that has been degraded, damaged or destroyed.
Society for Ecological Restoration (2002)
“Once an ecosystem has undergone ecological
restoration, it should be self-organizing, self-, g g,
sustaining, and capable of maintaining itself …”Clewell & Aronson (2007)
Restoration ≠ landscaping project

• Restoration initiates and directs this process
• Often not completely deterministic, though certain “assembly rules” frequently applyassembly rules frequently apply
• Design should consider autogenic & allogenic factors that may influence trajectory & endpoint of restoration
Diversity
Structural Diversity• Horizontal
• Vertical
Biological (species) Diversity• Richness
• Equitability
Topography
Environmental diversity
Consider key factors that underlay biodiversity
