Three endangered wild-dog brothers trek 4,100 km across Africa
Their eight-month journey is the longest recorded single mammal trek in Africa and a real-world test of whether wildlife corridors still connect.
Three endangered African wild-dog brothers traveled more than 4,100 km (2,500 miles) across Zambia in about eight months, the longest recorded single journey by a mammal in Africa. Researchers tracked them from Kafue National Park to the Luangwa Valley as they crossed roads, farms and other human-dominated landscapes.
Why it matters
The dogs survived because pieces of habitat remain connected. Other tracked dogs died, probably in snares, showing how fragile those corridors are.
How much agreement is there?
Broad agreement. Researchers agree the journey demonstrates the value of landscape connectivity. Debate is mostly about the best mix of protected areas, corridors and community-based conservation.
Could someone help?
Support anti-snare programs, ranger teams and conservation groups that protect wildlife corridors rather than only fenced reserves.
