Lecture 12 Flashcards
what are goals for natural systems?
- maintain ecological integrity 2. maintain biodviersity 3. protect species at risk
fine filter:
used in specal cases like certain species or stage of succession
project based management plan
remediation:;
the action of remedying something, in particular of reversing or stopping environmental damage. Focused on fixing the process rather than the end-point
what is step 2?
design an explicit model of your system
stp 5?
implement management and monitoring plans
Using The Natural Variability Concept To Set Landscape Management Goals recognizes what?
that variability is a vital attribute of natural systems
step 6?
analyze date and communicate results
step 4?
develop a monitoring plan to test your assumptions
what are fsctors influencing succession ?
- soil
- landforms
- disturbance
- organisms
- environment
- time
what is step 1 to the adaptive management plan?
clarify groups mission
what are management goals for degraded systems?
- re-establish ecological processes 2. rehabilitate the system 3. eliminate invasive species 4. increase or maintain native species
mitigation-
the action of reducing the severity, seriousness or painfulness of something. Can be an outcome of restoration
rehbailitation:
the disturbed site will be returned to a form and productivity in conformity with a prior use plan.
define restoration:
the act of restoring to an original state that is perfect and healthy
In the case study of fire in the blue mountains, if the stake holders do not like fire, how will they shift the SRV curve?
shift it to the left
define coarse filter:
assumes maintaining landscape patterns and processes will ensure species, community, ecosystems, adnd landscape persistence,
site regional management plans
native component in a landscape or ecosystem include:
- abiotic components 2. biodiversity in both landscape and species 3. ecosystem proccesses like fire, flooding and predtion
social range of variation:
the range of ecological condition that society finds acceptable at any given time.
what are 4 values affecting success of ecological resotration?
- values- if they are narrow and anthropocentric 2. ecological circumstances- poor with irreversible damage 3. social commitment- low 4. data and knowledge- judgements
step 3?
develop a management plan that maximizes results and learning
when does an ecosystem have integrity?
when they have their native components intact
replacement-
provide or procure a substitute or equivalent in the place of.
Using The Natural Variability Concept To Set Landscape Management Goals Recognies that disturbances are 2 things
- cause spatial and temporal variation in the structure, functioning and composition of landscapes 2. sustain ecological systems and species
revegetation-
is the establishment of vegetative cover on a previously disturbed site
