Lecture 2 Flashcards
advantages to fine filter?
- prevent loss of at risk species or vegetation communities 2. management goals are focused and measurabke
Hedging:
strategy that reduces the temporal variance in fitness at the expense of a lower mean fitness. Based on betting.
optimal control:
predictable sytem, easily manipulated with preditablle outcomes.
scenario planning:
strategic planning method to make flexible long-term plans.
what are disadvantages to coarse filter?
May miss some species, communities or ecosystems
what are the principles of vegetation management?
- Need clear, measurable objectives
- vegetation management plan
- work with plant community succession attemption to guide or nudge its direction
- prompt action to treat undesirable vegetation is critical to success
- integrate treatments for success
- monitor vegetation frequently
what are the approaches to resource management according to uncertainty and contrallability.
If an action does not acheive the expected results it is because: (4)
- Assumtion were wrong
- actions were poorly executed
- conditions at the project site have changed
- your monitoring was faulty
what is the adaptive management cycle?
- Assess problem
- Design
- implement
- monitor
- evaluate
- adjust
Disturbance is designed to alter successional processes by:
- Creating patches or sites for habitation 2. Controlling colonization of patches 3. Controlling species performance
how is basic research different to adpative management
fine filter in landscape management
used in specieal cases like in certain spcies or stages of succession
what are the advantages to coarse filter?
- need little information except for historic dustrbance regimes 2. based on landscapes 3. efficient
systematically implementing actions for a desired outcome involves:
- evaluating your project site
- developing assumptions abou what is occurring
- decide what actions are available to affect these events.
what are 4 things adaptive management is not?
- an excus to change your mind
- management by trial and error
- conflict resolution
- simply monitoring
what does project design involve?
Includes identification of project goals and objectives and site assessment for a project.
what is the most important aspect of adaptive management?
knowledge integration.
disadvantages to fine filter?
- May miss some species, communities or ecosystems 2. requires in depth understanding of species habitat or conditons required to maintain specific vegetation community 3. $$$$$
what does monitoring detmerine?
if the project was constructed properly and if it is functioning as required.
coarse filter approach to management:
Assumes maintaining landscape patterns and processes will ensure species, community, ecosystem and landscape persistence.
what is adaptive management:
incorporates research into conservation action. Specifisally it is the integration of desgin, management and monitoring to systematically test assumptions in order to adapt and learn.
