چکیده مقاله:

Kah-Kuh forest, a preserved area within Hyrcanian relict forests, with an area of 900 ha is located in the north of Iran. This area, located in 10 kilometers southeastern of Lahidjan and between 300-1100 m.a.s.l. The floristicphysiognomic investigation which was performed by fieldwalk procedure (2017-2018) showed that flora of this region included 110 plant species which belong to 75 genera and 30 families. The largest plant families, in terms of number of species, were Poaceae, Rosaceae, and Asteraceae. The genera with the highest species richness are Carex (4 taxa), Geranium and Viola (every 3 taxa). Geophytes (46 taxa, 46.46 %), Phanerophyte (21 taxa, 21.21 %) and Hemicryptophytes (17 taxa, 17.17 %) were the most important structure groups of the local biological spectrum according to Raunkaiaer method. The high proportion of geophytes in the studied area primarily reflects the long period of wetness during the growing season and relatively high annual precipitation
