Electrocution, rail hits, habitat loss: Man-made hazards behind 25% elephant decline in 8 years | Dehradun News - The Times of India Dehradun: Electrocution, railway collisions, poaching, and widespread habitat loss have emerged as the leading causes of elephant deaths across India,.

According to India's first elephant census since 2017, the Asian elephant population has declined by 25% in 8 years, with electrocution, railway collisions, poaching and habitat loss as the leading causes of elephant deaths.

How is the effectiveness of terrestrial protected areas to conserve biodiversity measured? This systematic map aims to collate and synthesize global evidence on the methods and metrics used to assess the effectiveness of terrestrial PAs in biodiversity conservation.

πŸ›‘οΈ Protected areas (PAs) are a cornerstone of biodiversity conservation. But how do we know whether they truly work? We reviewed 275 articles & 280 studies to map how terrestrial PA effectiveness is measured. Here's what we found:

Unprecedented continental drying, shrinking freshwater availability, and increasing land contributions to sea level rise Drying continents, extreme drought, and groundwater depletion are shrinking water availability and increasing sea level rise.

After a long absence from Twitter, I'm now on Bluesky. Looking forward to sharing thoughts, research, and rants about the lack of attention paid to water. Let's kick this off with a new paper alert. Please share widely. Title says it all. Please help me grow followers www.science.org/doi/10.1126/...

Drawing on data from over 400 forest plantations in Himachal Pradesh, India, we show that improved forest outcomes (increasing forest cover, improved forest-based livelihoods) are strongly associated with long-term participation by local people in decision-making. iopscience.iop.org/article/10.1...

Here, we reconstructed #tropicaldrywoodland change since the 19th century, identified #archetypes of change, and explored their relationship with current megafauna distributions.

Findings:

1. Massive Historical Loss: India has lost over 22 million hectares of dry woodland since the 19th century.

Overlay of the values within the last quartile (higher values) from each climate risk metric for scenario SSP3-7.0. Areas in the map are color-coded based on their overlap with hotspots of exposure identified based on different climate metrics (Local, local velocity; Analog, analog velocity; Magnitude). Areas with no analogues within the 1500 km search radius (NA values on land) are shown as blank spots (i.e. central Greenland). Map lines delineate study areas and do not necessarily depict accepted national boundaries.

Unpacking three decades of restoration in the Western Himalayas A review of restoration efforts in the Western Himalayas found that government-run afforestation initiatives led the way in Himachal Pradesh.

Excellent article covering a new systematic review of restoration in the Western Himalayas. Concerning findings, similar to my work, are that restoration has tended to focus on (not very successful) tree plantations on govt. land, with overuse of exotic species: india.mongabay.com/2025/05/unpa...

Ecological restoration, socioeconomic policies, and political stability have facilitated the recovery of tigers within their historical range, despite high human densities.
