Restoration Ecology Quiz 1

What are the first 4 principles underpinning ecological restoration?

has stakeholders
has many types of knowledge
includes native reference ecosystems
supports recovery processes

What are the last 4 principles underpinning ecological restoration?

has clear goal and outcome
seeks highest level of recovery
gains cumulative value
is part of a continuum

What is traditional ecological knowledge?

passed down through generations by cultural transmission about relationships between living things in environment

What is 2 eyed seeing?

combining indigenous knowledge with western science to view environment as a whole

What are different ecological scales?

micro scales
landscape scale
continental scale

What is adaptive management?

being able to adapt processes during restoration

What is passive restoration?

removing harmful things and letting the site restore itself

What is active restoration?

being hands on with restoration site like planting seeds to help it

What is process-based restoration?

instead of building infrastructure to help site you fix the root of the problem and let nature do heavy lifting

Why are reference/historic systems so important?

to be able to compare a current state to past state and use it determine what you want current site to look like now

What is predicted trajectory in ecology?

the actual direction an ecosystem is changing to

What is desired trajectory?

the target path you want the ecosystem to take

What is intermediate trajectory?

the middle space when a site is not in a dire need but is still unstable

What is an alternative trajectory?

instead of following a desired path it diverges due to environmental factors

What is an undesirable trajectory?

where an ecosystem goes off to an unstable or degraded state

What are internal processes?

physical, biological and chemical components that exist within the ecosystem

What are external drivers?

human interaction
climate change
resources

What is the importance of the relationship between internal processes and external drivers?

can hlep dictate how an ecosystem function, adapts and respond to change

What is disturbance theory and an examaple?

how physical events can disturb the biological or physical state of ecosystem
ex is wild fires

What is succession theory?

explains how an environment develops over time and throughout different stages

What is community assembly theory?

explains how a mix of species comes together into a specific ecosystem

What are threshold dynamics?

a threshold where a change can push a ecosystem over a critical tipping point

What is the alternative stable state theory?

where an ecosystem gets pushed over threshold and shifts to a new stable condition

What are indicators of dynamics in an ecosystem and give an example?

things we can measure to see how a ecosystem might change/develop
ex is species interactions

Why are landscape context and spatial scale important?

indicators on recovery of ecological processes and patterns

What are a few persistent themes in linkage of theory to restoration?

history
environmental factors
landscape context

What are some indigenous approaches to restoration?

viewing humans as apart of the ecosystem and not a separate being
