A study conducted in the Kangra district of Himachal Pradesh between 2020 and 2024 identified 617 active nests across 553 trees. [^1]

Researchers affiliated with the Indian Institute of Wildlife Research in Dehradun found that endangered white-rumped vultures in Himachal Pradesh preferentially nest in old and thick cedar trees. [^2]

The study concludes that conserving old and thick cedar trees is essential for protecting the white-rumped vulture population. [^3]

A study by researchers at the University of Eastern Finland analyzed more than 70,000 wind-damaged areas in boreal forests to assess long-term vulnerability. [^4]

The study found that forests affected by wind damage remain vulnerable to subsequent bark beetle or snow damage for years, depending on forest structure, climate, topography, and species composition. [^5]

Approximately 80 percent of the 617 active nests were located at elevations between 600 and 800 meters. [^6]

Doctoral researcher Qianqian Tian stated that forest disturbances often change the conditions under which subsequent disturbances occur. [^7]

Professor Blas Mola-Yudego noted that structurally heterogeneous forests in southern Finland may require different management attention than pine-dominated stands in North Karelia. [^8]
