Imagery data of more than 600 endangered species along the Yarlung Zangbo Grand Canyon in the Tibet autonomous region has been recorded, according to a team conducting a biodiversity image survey in Tibet.

Since 2010, the team has collected data during three such surveys along the canyon.

The team said on Wednesday that the achievement has important reference value for biological scientific surveys and research along the Yarlung Zangbo Grand Canyon.

"These imagery data of endangered species are not only simple specimen photos, but reach the level of imagery of photographic art and biological use," said Luo Hao, head of the team.

"These imagery data display the all-directional survival situation, the morphological characteristics, the geographical distributions and the protection messages of fauna and flora along the canyon."

According to the team, the hundreds of endangered species, including birds, amphibians, insects and plants, they recorded on the last three surveys only accounts for a tiny fraction of the species in the canyon.

The survey team will continue to do observations and make records along the canyon.
