Abstract
Hippophae
salicifolia
D. Don or Sea
buckthorn is one species that has great potential for
improving ecological and economic developments in the mountain
areas of North Sikkim. The plant is found naturally at
altitudes ranging from 2,377 to 3,093 m. in riverine
(riverside or torrential side) and non-riverine (non river or
non torrential side) areas where geo-physico-chemical
parameters like aerial temperature, aerial moisture, soil pH,
soil temperature, and soil moisture varied significantly. We
analyzed ecological parameters and species association using
standard quadrates. Actinorhizal plants invade nitrogen-poor
soils because of their ability to form root nodule symbioses
with N2-fixing actinomycetes known as
Frankia.
Variation in nodulation with respect to plant height was also
observed. This was higher in riverine areas compared to non
riverine sites at higher
altitudes.
