Kaziranga Tiger Reserve Population Assessment

The Kaziranga Tiger Reserve, located in Assam, India, has been recognized for having the third-highest density of tigers in the world. A recent large-scale assessment revealed that this reserve has an estimated density of 18.65 tigers per 100 square kilometers. The findings were made public in a report titled ‘Status of Tigers in the Kaziranga Tiger Reserve’ for the year 2024, which is based on a Phase IV tiger monitoring initiative mandated by the National Tiger Conservation Authority.

Key Findings:

• The recent survey documented a total of 148 tigers in the Kaziranga Reserve. This reflects a significant increase from previous counts: 104 tigers in 2022, 99 in 2018, and 96 in 2014.
• The report indicates that the increase in the tiger population is partly attributed to the inclusion of the Biswanath Wildlife Division in the sampling for the first time, which accounted for 27 of the newly recorded tigers.
• In the Eastern Assam Wildlife Division, the tiger population grew from 104 in 2022 to 115 in 2024. The Nagaon Wildlife Division remained stable, retaining its count of six tigers.

Survey Methodology:

• The assessment was conducted over 103 days using 293 paired camera traps across an area of 1,307.49 square kilometers. The cameras captured 4,011 images of tigers in 242 locations.
• Identification of the tigers was done through unique right-flank stripe patterns, leading to recognition of 148 adult tigers, comprising 83 females, 55 males, and 10 of undetermined gender.

Ecological and Conservation Insights:

• The diverse ecosystems in Kaziranga, which include Eastern wet alluvial grasslands, semi-evergreen forests, tropical moist mixed deciduous forests, and wetlands, provide suitable habitats for tigers and megaherbivores.
• Ongoing conservation efforts have included strict protection measures, anti-poaching initiatives, habitat restoration, and community-based conservation strategies.

Challenges:

• Despite the positive growth in tiger population, there are persistent challenges such as habitat fragmentation, human-wildlife conflict, and pressures from agricultural expansion and infrastructure development surrounding the tiger reserve.
• Climate change has also introduced complexities, necessitating adaptive management strategies to ensure the long-term viability of tiger populations.

Key Points:

• Kaziranga has the third-highest tiger density globally with 18.65 per 100 sq km.
• The current tiger count stands at 148, up from 104 in 2022.
• Inclusion of Biswanath Wildlife Division led to the discovery of 27 new tigers.
• Survey utilized 293 camera traps over 1,307.49 sq km, producing 4,011 images.
• Ecological diversity of Kaziranga supports tiger and megaherbivore habitats.
• Conservation measures include anti-poaching, habitat restoration, and community involvement.
• Challenges include habitat fragmentation, human-wildlife conflicts, agricultural pressures, and climate change.

These findings emphasize the importance of conservation efforts and the need for continued monitoring and adaptive strategies to address existing challenges in protecting tiger populations in the Kaziranga Tiger Reserve.
