and other organisms usually lacking
developed soil
-
-
-
describes how brand new
surfaces will develop fully
fledged plant communities
with associated ecosystems
Weathering +
Succession
-
-
dominant species at each level
enriches soil making conditions
more suitable for taller, more light +
nutrient competitive vegetation
to be dominant @ next seral stage
Definitions
-
pioneer community -
first hardy, resistant species
to colonise extreme or hostile
conditions
-
seral stages -
distinctive stages in sequence changing plant communities until the climatic climax is reached
-
-
Plagio-climax
Vegetation
-
-
clearance,
burning + grazing
examples:
- heather moorlands in upland areas Britain
- Savanna grasslands
- temperate grassland (N.America Prairies)
