The habitat is restricted only to rocky type and
some of the disturbance due to tourism and boating
might be attributing to the low diversity of the lake.
Akheraj Pond
The pond is situated (26° 17′ 51 N and 72° 58′ 54
E) about 7 km west of Jodhpur besides Kaylana
Lake and is filled with the excess water of
Kaylana Lake which is a small water body sized
0.15 km
2
surrounded by croplands and commercial buildings (Table 17.3). This small water
body is a very good bird watching site as due to
its small size with shallow banks with vegetation
of Typha latifolia (Typha) and Prosopis juliflora
which support several resident birds like purple
moorhen (Porphyrio porphyrio), white-breasted
waterhen (Amaurornis phoenicurus), Indian
moorhen (Gallinula chloropus), and many other
reed loving birds. The floating vegetation is
mainly water hyacinth (Eichhornia sp.) and submerged vegetation is mainly Vallisneria spiralis.
About an average of 1,457 individuals of 106
species of 57 families were recorded from observations from 2008 to 2012. Alpha diversity was
found second highest (α = 3.79). Out of 106, only
44 species were wetland species (Table 17.3 and
Fig. 17.2).
The water body is small and shallow, its maximum potential of diversity (H max ) was found to be
4.66, and the evenness of this water body was
ranked 2nd (E = 0.81) which suggest that even after
disturbance, the wetland holds good distribution
of all occurring species. The pond is disturbed in
the recent past, and the crop fields surrounding
the pond are increasing the organic contents and
increasing eutrophication. Waste disposal near
the pond is another threat. Akheraj pond is one of
the most diversified ponds in the Jodhpur.
Umed Sagar
The pond is located at the latitude and longitude
coordinates of 26.15′58 N and 72.56,32 E near
Jodhpur (Table 17.3). Umed Sagar is an artificially constructed dam by Maharaja Umed Singh
in 1933 for the supply of drinking water. This
pond spreads over an area of 27 km
2
. It is located
near Kaylana Lake.
It is an open wetland surrounded by crop fields
from three sides with a dam on the other side. The
banks are muddy and bounded by thatched biofencing of dead branches of P. juliflora. About an
