Area No. II. ( See 'portion marked B on map.) 
The Kala Nadi Catchment Area in the Karwar and Supa Ranges 
of the West and North Kanara Forest Divisions. 
(1) Name and Situation. 
The area is situated on the West Coast of the Bombay Presidency 
in the North Kanara Collect orate and consists of the catchment area 
of a river known as the Kala Nadi, which taps the upper slopes of the 
Western Ghats and finds its way to the sea at Karwar, the head¬ 
quarters of the District and a small port, situated in a very fine bay. 
The valley, formed by this river, is fairly broad and open as far as Kadra, 
some 20 miles from the sea, and in this area, which is under cultivation, 
there are relatively few bamboos, except along the banks. Above Kadra 
the valley gradually narrows in, until above Bobrigadda it forms a 
ravine, through which the river passes in a deep channel some 100 
yards broad. The hills, on each side of the river above Kadra, rise to over 
2,000 feet and are clothed throughout with fine high forest. The village 
of Bobrigadda is about 40 miles from the sea. Above this village, the 
river, which is still a fine one, passes through the Gund slopes to the 
foot of the Ghats. The slopes on either side are covered with heavy teak 
and bamboo forests. The extreme limits, from which it would probably 
be practicable to exploit bamboos, is 40 miles above Kadra, or a distance 
of 60 miles from the sea. i 
(2) Description of the forests. 
In the lower reaches, especially near the liver and up its tributaries, 
there occur moist deciduous forests, while the greater portion of the 
lower and middle slopes are covered with dry deciduous forest, contain¬ 
ing, above Birkol village, a fair quantity of teak and bamboo forest. The 
higher slopes are generally covered with evergreen forest, in which no 
bamboos are found. The prevailing species of bamboo is Bambusa 
arundinacea, known locally as the “ Daugi ” bamboo. It grows to a 
large size in the lower areas and is still of fair size on the dry slopes, 
while, on the Gund plateau above, an area also included in this scheme, 
it is found growing to a great size. The other bamboos found in these 
forests are Dendrocalamus strictus and Oxytenanthera monostigma , of 
which the former species in particular is not common.
