Silver-Backed Chevrotain
Silver-backed chevrotain was rediscovered in Vietnam after nearly 30 years without confirmed sightings. This tiny, elusive mammal was captured on camera traps in the Greater Annamites ecoregion, signalling a vital breakthrough in efforts to protect endangered species. The finding marks the importance of combining modern technology with local knowledge to safeguard biodiversity.
Rediscovery Context
The silver-backed chevrotain, also known as the two-tone mouse deer, was presumed lost to science for three decades. Its unexpected photographic evidence came from camera traps set in a southern Vietnamese lowland forest. This rediscovery renews hope for many species thought extinct and puts stress on the value of persistent conservation.
Appearance and Habitat
The chevrotain is a small hoofed mammal, about the size of a rabbit. It has a russet head and front legs, silver-grey body and hind legs, and a white grizzled rear. It inhabits dense forests in the Greater Annamites, a biodiversity hotspot spanning Vietnam and Laos. Its secretive nature and remote habitat contributed to its long absence from scientific records.
Threats to Survival
The main threats to the chevrotain include predation by wild animals like leopards and wild dogs. However, the greatest danger is human hunting, especially through snares. These traps indiscriminately capture many forest species, causing severe declines. Conservation efforts now focus on reducing snaring to protect the chevrotain and other vulnerable animals.
Survey Methods and Findings
Researchers gathered local ecological knowledge from villagers and forest rangers to identify likely chevrotain habitats. They deployed camera traps over several months, capturing hundreds of photos and multiple independent sightings. This method confirmed the species’ presence and provided data to guide further protection measures.
Role of Local Communities
Engaging local communities was crucial for the survey’s success. Their knowledge helped locate the animal and informed conservation strategies. This collaborative approach is vital for future efforts to find and protect lost or endangered species worldwide.
Broader Conservation Implications
The rediscovery emphasises that species thought extinct may survive in unexplored or inaccessible habitats. It marks the need for urgent conservation actions, habitat protection, and anti-poaching measures. Protecting one species often benefits entire ecosystems, preserving biodiversity at large.
