Camera traps are not the intricate and elaborate devices you might imagine. These innovative conservation tools are in fact nothing more than everyday cameras, armed with infrared sensors that take a picture whenever they sense movement in the forest.
A July 2012 camera trap study in Nepal identified 37 individual tigers—a marked increase from 18 tigers counted in 2009. The tigers were monitored over a three-month period inside Bardia National Park in Nepal and the Khata wildlife corridor in the Terai Arc Landscape.
Wildlife migrations depend on natural wildlife corridors—passages that allow regular travel, seasonal migration or population dispersal of different species. Any barriers to this basic need are a threat to healthy wildlife populations. WWF works with businesses, government leaders, public and private land managers, hunters, anglers, farmers and ranchers to ensure wildlife connectivity is a part of all land and wildlife management decisions.
Climate change is causing many Eastern Himalayan glaciers to melt faster than ever observed and in the process they leave behind pools of water that form glacial lakes. Weak walls of earth and rock contain the water but can burst suddenly, resulting in massive flooding downstream that is catastrophic for local communities.
