Jamnagar (Old name Nawanagar) is another
coastal city. Area wise, it is smallest
Mahanagar
Palika
in Gujarat with high density of human
population and very low density of tree cover.
The basic facts about the city are as follows.
Neem and Bakam Neem are most important
trees in the city. Also, Vad is present in good
number along roads and in garden.
Human population 5.29 lakh
Area of city
3,434 ha
Tree population
45,900
Tree density
12.9 trees/ha
Tree cover
163 ha (4.7%
of geographical area)
Trees per 100 person 8.7
Only about 74 species of trees were encountered
in the city and ten most important of them have
been given in Table-22.
The coastal line of the
Mahanagar Palika
is
saline and does not support trees. The inter-
tidal areas, beyond the boundary of the city,
have forest cover of mangroves. Saline areas in
periphery of the city is filled up by the bushes of
Prosopis chilensis
.
In Jamnagar, 315 trees are large having girth
above 250 cm. Number of
Ficus
species-Vad
is also good. These trees were raised before
Independence by the then king of Jamnagar.
Distribution of about 45,880 trees in different
girth classes has been presented in the above
graph. Young trees or trees having low girth are
relatively less. This indicates that there is a scope
of planting suitable species in the available
space within the municipal corporation area to
improve green cover.
Conclusion:
This city in Saurashtra has very poor
tree cover which needs to be improved by three
times. Some area of the city is saline. Thus a
target to increase tree cover to the level of 10 %
of the city area should be achieved by planting
tall seedlings of suitable species.
