The application of population modelling techniques to the development of Non-detriment Findings for Galanthus elwesii in Turkey.

Matthew J. Smith

Abstract

The minimum criteria a population model should meet in order to aid

in the making of non detriment findings (NDFs) should be a demonstrable

ability to predict changes to the population size following

actual harvesting regimes to a desired level of accuracy. This case study

outlines how population models could be developed and used to aid

in making NDFs for G. elwesii, the Turkish Giant Snowdrop. This taxon

is particularly suited to developing such a quantitative framework

because the populations are visited annually (facilitating data collection),

they appear to have relatively stable abundances (suggesting

relatively low stochasticity), and annual collections of relatively large

quantities for international trade is likely to continue to for the foreseeable

future. Furthermore, the establishment of such a quantitative

framework will be a valuable example for those wishing to develop a

similar system for other CITES taxa.
