1
Pollen Analysis Correlate Quaternary stratigraphic units
Reconstruct vegetation history To investigate the impact of human activities on late Quaternary vegetation and landscape in many parts of the world
2
Pollen Analysis Pollen Characteristics Resistant to decay
Morphological characteristics specific to plant groups Produced in vast quantities Reflect the natural vegetation of a location Small ( u)
3
Pollen Analysis Pollen production
All plants that have sexual reproduction Productivity depends on dispersal mechanism Autogamous (self fertilised) = very small amounts of pollen Entomophilous/zoophilous (insect & animal) = small amounts of pollen Anemophilous (wind) = large amounts of pollen
4
Pollen Analysis Pollen dispersal
Most pollen not carried far from site (1 km) Some can travel very long distances Dispersal as a function of: grain size wind (direction speed) precipitation Plant habit and dispersal low vegetation trees
