             East:- Thence along the right bank of the Nalapara nadi for about 155 chains the boundary pillar No.1 at northeast corner of Block 11 of the Bhadlapara Tea Estate thence along the northern boundary of this Block  for about 52 chains to boundary  pillar No.2 at its northwest corner, thence along the western boundaries of Block 11,8 and 7A of the said Tea Estate for about 154 chains through boundary pillars 3,4,5,6,7,8 and 9 to boundary pillasr 10.

             South:- Thence a demarcated line at a bearing of 240◦ for about 28 chains to boundary pillar 11, on the track to Dharamjuli, thence at 270◦ for 77 chains to boundary pillar 12, thence at 292◦ for about 40 chains to boundary pillar 13, thence along the northern boundary of grant 300 of the Atharikhat Tea Estate for about 39 chains to boundary pillar 14, thence at 286◦ for 41 chains to boundary pillar 15, thence along the northern boundary of grant No. 119 N.R. of the same Estate for about  60 chains to boundary pillar 17, thence along the western boundary of grant NO.3/4N.R.

 The Range is divided into five Blocks measuring a little over 5 sq. km. on an average. The area of each block is given below:- 

Block  Number Block  Area (ha)
1   3.75
2 5.2
3 4.8
4 6.5
5   5.97

1.7. Statement of Significance:-

             The sanctuary is an important habitat of Pigmy hog (Porcula salvania) and Hispid hare (Caprolagus hispidus). Sightings of these two animals were reported from the area till the mid-nineteenth century. However their sudden reappearance in the area in the year 1971 led to the recognition of the area as of immense importance for the survival of these two animals. The two animals occur over a very narrow geographical range. Similarly, Bengal Florican (Houbaropsis bengalensis) is a critically endangered bird that has a resident population within the fringe of Manas National park.
