A status survey of Blue was conducted between 25 May-12 June, 2007 in Sundaha, Seng, Dogadi, Phagune, Barse and Gustung blocks of DHR. Of the 665 sq. km. potential blue sheep habitat, about 60% of the area was surveyed.  A total of 852 blue sheep were counted in 73 different groups of which 81.92% were classified into different age and sex groups. The average group size of the observed blue sheep is found to be 11.7% individuals per group ranging from two to 79 animals. The average population density of blue sheep in the reserve is found to be 1.28 animals per km2. Of the 698 animals that were classified into age and sex, 263 were rams, 307 were Ewes, 59 were yearlings and 39 were lambs. Of the total, 126 (18.05%) were classified as trophy rams, 92 (13.18%) were medium rams and 45 (6.45%) were young rams (Table 3). The proportion of trophy rams compared to other rams is found to be higher than the earlier studies. The mean sex ratio is found to be equal to 86 males per 100 females and the yearling to 100 Ewes ratios is found to be 29.

Efforts were also made to survey Himalayan tahr as and when possible. One and half day time was spent by team in Sundaha block where 53 individuals were recorded with 30 males, 14 females, 8 yearlings, 1 lamb & rest unclassified. Due to only about 0.5 days time spent and found in different habitat, only 1-11 individuals were recorded in rest of the blocks. The sex ratio classified (53) Jharal in 30:14 (214 male: 100 female).

The existing quotas of blue sheep hunting, 6 in Dogadi and 4 each in rest of 5 blocks can be safely continued. In case of higher demands 2 more quotas can be added to Barse, Dogadi & Sundaha for next 5 years.

Himalayan tahrs can be hunted in all the blocks. Sundaha can sustain 4 and rest of blocks can sustain 2 Himalayan tahrs each year.

If the demands of Jharals increase a separate census along with the hunting operation can be conducted to certain the status & fixing the quotas.

If new companies are interested, Surtibang block could be allowed for Himalayan tahr hunting.

Regular census is backbone to the sustainable harvest, thus counting one block each year to complete all the 6 blocks in a period of 6 years could be practical and reasonable period for regular census.
