The study of some wild and cultivate Plants in Hammedan City

The Cities are one of the important nich for many Plants and Animals. The diversity of spieces in the cities is more than the outside of the Cities. So the Biotops of the Cities have research value. Relating to introduce some Biotops such as cultivates Plants, rudural plants and also wild plants in Hamedan, some of the Biotops and ecosystems of Hamedan have been studied. Up to now about 50 families, 202 genus and 285 spieces from wildherba elements and also 14 woody plants (Trees and Shrubs) 20 genus and 23 spieces that are cultivated plants are collected and determined from Hamedan. The distribution of many cultivated plants within the areas of industrial, fallow, subnatural and near the river in Hamedan are have been studied. Results showed that the Asteraceae with 47, Poaceae with 31 and Fabaceae with 22 spieces are the most aboundance families in studied areas. The families of Brassicaceae with 17 and Lamiaceae with 12 spieces have the second place and are very important. Appendix table No. 2 represented a list of all families, genus and spieces, wich are know in Hamedan untill today. Many Biotops in Hamedan, like other Iranian Cities are in danger. The result of this problem is the reduction and return of spieces diversity and perhaps extinction of many spieces in the City.
