ABSTRACT
The present survey entitled “Regeneration status of Anogeissus latifolia Wall ex Bedd. in
Kunihar Forest Division, H.P.” was carried out during the year 2018-2020 with the aim to study the
floristic composition, phytosociology, regeneration and soil physico-chemical properties at different
elevations and aspects in Kunihar Forest Division (Solan), H.P. The study area was divided into three
elevation zones, lower (E1) = 600-800 m, middle (E2) = 800-1000 m and upper elevations (E3) =
1000-1200 m in northern and southern aspects. Structural and functional parameters of trees, shrubs
and herbaceous vegetation in each elevation and aspect were studies by laying down four sample plots
0.1 ha for trees, one sub plot of 5 x 5 m2 and a quadrate of 1 x 1 m2 were marked to study shrubs and
herbs characteristics in each sample plot respectively. Composition, density (indi. ha-1), basal area (m2
ha-1) of different vegetation layer of tree, shrub and herbs layers were analyzed. The data were
analyzed by using factorial randomized block design. The study area constituted of 112 plant species.
Maximum total density and basal area of trees were present at lower elevation on southern aspect
which showed a decreasing pattern with elevation. Shrubs and herbaceous vegetation had highest total
density and basal area on southern and northern aspects, respectively and showed an increasing trend
with elevation. In the study area, Anogeissus latifolia was the most dominating tree species on all
elevations and aspects except on northern aspect at upper elevation where Pinus roxburghii was
dominant. The regeneration study was conducted to know the regeneration status of Anogeissus
latifolia, indicating maximum regeneration success (43.75%) at lower elevation on southern aspect
and showed a decreasing trend with increase in elevation. Soil organic carbon, available nitrogen and
available phosphorus were higher on northern aspect and showed an increasing pattern with elevation.
Available potassium and electrical conductivity were higher on northern aspect while bulk density and
pH were higher on southern aspect and showed a decreasing trend with elevation.
