Implications of salep collection for the conservation of the Elder-flowered orchid ( Dactylorhiza sambucina ) in Epirus, Greece

Table 3 Population distribution features observed by us and their implications for salep production

Site code	Extent, L² (ha)	Dimension D (est.)	Population N (est.)	Potential salep yield (kg)
ANTH	1.76	1.38	188	0.072
ANIL	17.58	1.30	119	0.045
TYMF	1.79	1.26	82	0.031
LAKM	1849.00	1.30	25,751	9.829

The estimate of the extent of Lakmos site was approximate, obtained by finding the extremes of the local population. The fractal dimension, D, was calculated using Eq. (2) and the population, N, using Eq. (3)
