Abstract:

A study was conducted from 1997 to 2000 to determine the effect offelling top dying
affected sundari (Heritiera fames) trees on the regeneration status in those areas of the
Sundarban. The newly recruited seedlings ofsundari (H.fames), gewa (Excoecaria agallocha)
and kankra (Bruguiera sexangula) were significantly higher in the felled areas compared to
unfelled areas almost all the years. But seedlings of passur (Xylocarpus mekongensis) and
goran (Ceriops decandra) were found significantly higher only in 1997 and 2000 respectively
and amur (Amoora cucullata) in 1997 and 1998 in the felled areas. Moreover, seedlings
recruitment of all species together was significantly higher in the felled areas. Among the
recruited seedlings, H. fames and E. agallocha constituted the highest numbers both in the
felled and unfelled areas. Therefore, salvage felling of the top dying affected sundari trees is
recommended to avoid wastage of wood and to improve regeneration status.

Abstract:

A study was conducted from 1998 to 2001 in the Sundarban mangrove forests of
Bangladesh covering three salinity zones to determine the effect of deer (Axis axis) on the
newly recruited seedlings of sundari (Heritiera fames), gewa (Excoecaria agallocha), kankra
(Bruguiera sexangula), passur (Xylocarpus mekongensis), baen (Avicennia officinalis), goran
(Ceriops decandra) and amur(Amoora cucullata) in the fenced and unfenced plots. Tire browsing
effect of deer wasfound to vary from species to species because of differences in palatability.
A significant damage of deer was found in the regenerated seedlings of B. sexangula,
X. mekongensis, A. officinalis and H.fames. No significant effect was found for E. agallocha,
C. decandra and A. cucullata

Abstract:

Survival, establishment and early growth of six major and economically important
mangrove plant species, namely sundri (Heritiera fames), gewa (Excoecaria agallocha),
goran (Ceriops decandra), passur (Xylocarpus mekongensis), kankra (Bruguiera sp.) and
baen (Aviccnnia officinalis) were studied in two salinity zones (moderate and strong
saline) of the Sundarbans mangrove forests of Bangladesh at the age of five years after
planting. The objective of the study was to enrich the vacant and poorly regenerated
areas of the Sundarbans for its sustainable production and management.
The percentages of planted seedling’s survival and establishment by fencing at
moderate saline zone were 84.9, 74.3, 63.5, 60.6, 40.6 and 38.9 for gewa, goran, sundri,
kankra, passur and baen respectively. The average height growths of these species were
1.94 m, 1.04 m, 0.90 m, 1.18 m, 1.71 m and 2.90 m respectively. Except gewa and goran
all the seedlings of other four species died due to deer browsing when planted in
unfenced condition.
