Research

Harriet Allen is a member of the Geography Department's Environmental Systems and Processes research group.

Harriet is a physical geographer with a range of research interests which focus on

  • Modelling the vegetation structure of Mediterranean ecosystems
  • The response of ecosystems to environmental change
  • Palaeoecological evidence for Holocene and contemporary environmental change

These areas of interest are firmly located within Mediterranean environments.

Current projects include:

  • Mediterrranean wood pastures for biodiversity - making the lynx
  • Modelling the landscape ecology of Mediterranean shrubland ecosystems.
  • Use of airborne LiDAR to characterise vegetation communities.
  • Use of multisensor ariborne data to model Mediterranean sclerophyllous vegetation communities (Crete and Portugal).
  • Holocene and contemporary vegetation dynamics of Mediterranean ecosystems.
