13. VegClass , Public domain, user-friendly software for data entry and meta-analysis; integrated with field proforma to support rapid vegetation survey
14. Sample page from VegClass showing PFT and species listings UNDESA, EFD Mtg Gothenburg Univ. 16-17 April 2009
15. Plant Functional Type ( me-pe-do-ct-ph ) Plant Functional Elements Adaptive PFTs are constructed from 36 generic PFEs according to a specific rule set. This system can be applied to all terrestrial vegetation Example of PFE combination me = me sophyll leaf size class pe = pe ndulous leaf inclination do = do rsiventral leaf ct = green c or t ex (photosynthetic stem) ph = ph anerophyte (perennial woody plant > 2m tall) Combining functional traits to describe a single plant individual (VegClass grammar)) UNDESA, EFD Mtg Gothenburg Univ. 16-17 April 2009
