settlement of the effect of marginal land use on plant diversity. The
location of this study was Sar Firouze Abad region with rainfall of over
350 mm and slope of over 12%. Five treatments in terms of land use (exclusion
area, grazed range, fallow, annual medic cultivation, wheat cultivation)
done with the repetition of five times. The factors, such as the number
of species and the number of plant bases in each species in each sampling
were measured. The method used here is based upon complete randomized
design applying Duncan test and Raunchier method for classification of
plant species and also Shannon-Wiener index of diversity and homogeny
utilized. The results show that there are 76 species belonging to 60 genus
and 19 families spreading in the region under study. The most dominant
families are Fabaceae with 15 species covering 20% and Poaceae with 13
species covering 17%, respectively. According to Raunchier method the
life form of the region species can be classified as Therophytes 66%,
Geophytes 3%, Hemicryptophytes 26% and Chamaephytes 5%. The results also
illustrate that the treatment of exclusion area has the most plant diversity
in comparison with treatments of fallow, annual medic cultivation, wheat
cultivation and range grazed.]]>Chamani, A.,19951995Cingolani, A.M., N.M. Imanuel and D. Sandra,200515757773Delitti, W., F. Anna, T. Louis and V.
