13 - Forest and Succession Flashcards
changing conditions let one set of species gradual replacement others
Ecological Succession
each stage of a successional process
Seral
Biotic community develops where none currently present, raw area
primary succession
Redevelopment of biotic community after partial destruction
secondary succession
last succession stage, relatively stable, long-lasting, complex, interrelated
“climax community” (not called that anymore)
plant and animal species over time replaced by similar species
mature community
progression through several seral stages, e.g., fire, returning to earlier stage
Cyclic Succession
natural or human-induced event/process interrupting ecological succession
disturbance
soil location where plant seeds accumulate, typically fire-succession community
Seed Bank
fire adaptation, retain non-dormant seeds in a cone or woody fruit until a fire (a species that has adapted to fire)
Serotiny
mature/climax community where vegetation is largely influenced by climate
climatic climax
field of study, and practice, help repair environmental damage challenging and costly, so better to avoid degradation
ecological restoration
diversity is high, if the forest ecosystem experiences moderate disturbance
intermediate disturbance hypothesis
human initiated/controlled ecological fire to restore natural fire regime forest management sanctioned burning of a select portion of forest
prescribed burning
