3% is Eurosiberian and the rest of it is covered<br />
by the elements of which the origin is<br />
unknown (Saya & Ertekin 1998).<br />
Karacadağ is one of the important plant and<br />
nature areas on which wild relatives of many<br />
Poaceae and Fabaceae plants grow (Özhatay<br />
et al. 2003; Anonymous 2004; Biricik et al.<br />
2006). Findings of many researches published<br />
in recent years highlight that wheat farming<br />
in the world has first time started in Karacadağ<br />
and its district included in “fertile crescent”<br />
(Nevo et al. 1986; Nevo 1992; Diamond<br />
1997; Heun et al. 1997; Jones et al. 1998; Nesbit<br />
& Samuel 1998; Lev-Yadun et al. 2000).<br />
Unfortunately, the activities which increase<br />
day by day by depending on population<br />
growth lead to unbearable pressure on the<br />
plant diversity. Forest vegetations have been<br />
destroyed because the trees (especially oaks)<br />
have been cut for making them fuel and thus<br />
replaced by steppe vegetations in which Astragalus<br />
L. is a dominant especially.<br />
Material and Methods<br />
Flora of Turkey (Davis 1965-1985; Davis et al.<br />
1988; Güner et al. 2000) has been used in<br />
identifying taxa as a basic resource. Other<br />
basic floras (Rechinger 1965-1977; Bor 1968)<br />
and the studies of Malyer (1983), Kaynak &<br />
Ketenoğlu (1986), Kaynak (1989), Ertekin<br />
(1994; 2002) and Kaya et al. (2009) were used.<br />
Braun-Blanquet (1965) approach was used in<br />
order to analyze the vegetation. e size of the<br />
relevés was estimated by means of minimal<br />
area and was determined 50 m 2 for steppe<br />
vegetation. Evaluations of the syntaxa were<br />
made by the study of Quézel (1973). Sørensen<br />
(1948) similarity index was used to compare<br />
defined syntaxa with the similar syntaxa identified<br />
in different regions in terms of their<br />
floristic compositions. <strong>International</strong> Code of<br />
Phytosociological Nomenclature principles<br />
were followed for denomination of the new<br />
syntaxa (Weber et al. 2000). Soil samples from<br />
the study area were analyzed according to<br />
Tüzüner (1990).<br />
