Fire as a natural disaster plays a major role in deforestation; is a major source of trace gases, aerosols and carbon fluxes. Approximately 7 percent of Iran area is covered by forests/and wooded lands. According to the ECE/FAO database on forest/other wooded land fires in Iran (1982-1995), the number of fires per year is 130 and the average area burnt per year is 5400 ha, but fires are not lar...

-gporocarps of hypogeous mycorrhizal fungi (truffles) are the major food of northern flying squirrels (Gluucomys satinus). The two subspecies of northern flying squirrels that occur in the southern Appalachians, G. s. colmatus and G. s. fuscus, are endangered species which are primarily found in the ecotone between high-elevation spruce-fir and northern hardwood forests. Our objective was to de...

the aim of study was to evaluate qualitative and quantitative characteristics of old trees in pattom and namkhaneh districts in the nowshahr, northern iran. the trees quantitative characteristics of dbh, total height, slenderness coefficient, trunk height, crown length, buttress height, and canopy cover area and qualitative characteristics of crown and trunk, i.e., health, vitality, and concurr...

Estimation and mapping of forest resources are preconditions for management, planning and research. In this study, we applied kriging interpolation of geostatistics for estimation and mapping of forest stock at-tributes in a natural, uneven-aged, unmanaged forest in the Caspian region of northern Iran. The site of the study has an area of 516 ha and an elevation that ranges from 1100 to 1450 m ...

[1] Accurate land cover reconstructions are essential to understanding the past and present biogeochemical and biogeophysical interactions between the land surface and atmosphere and the impacts of these interactions on climate. Here we quantitatively reconstruct late Quaternary shifts in woody cover across the Northern Hemisphere forest‐tundra ecotone, based on a synthesis of Northern Hemisphe...

BACKGROUND Human fasciolosis is deemed as an emerging/re-emerging infection, hence making it an important human parasitic disease. In contrast to northern parts of Iran, human cases of fasciolosis in southern Iran are rare and sporadic. We report a sporadic case of fasciolosis in southern Iran (Fars Province) who presented with prolonged fever. Our report could suggest that there might be new f...

For maintaining of Zagros forests role in wild life, water and soil conservation, the suitable solutions and methods for assessing the existing conditions and planning for management of this forests should be given. To detection of suitable sampling method to study tree density in the northern Zagros forest, Blake forest, in Baneeh region, Kurdistan province, and west of Iran was selected. 40 s...
