About
The 14th Assam Rhino estimation
- The rhino census in Manas Park was conducted in all three ranges: Bansbari, Bhuyanpara, and Panbari, with 71 estimated blocks.
- The park's current rhino population is believed to be 40.
- The park's rhinos have a male-female sex ratio of 1:1.
- The total number of calves born in the wilderness represents the availability of welfare aspects to care for rhinos in Manas National Park.
- Methodology: Total count or Direct count method
- A complete count is often used when a single species has to be reported in a well-defined, specified region.
- This approach assumes a detection probability of one, implying that every animal has a 100% chance of being detected during the counting.
Limitations of this method
- The disadvantages of this technique include undercounting since the presumption of a detecting probability of one is impractical, particularly if population closure cannot be demonstrated properly within a limited area of 10-20 square kilometers.
- Total count necessitates considerable visibility in order to view the creatures from a distance, which is impossible with "shy, cryptic animals".
- The level of accuracy cannot be estimated in total counts.
