Efforts to restore wildlife populations are bearing fruit, with photographs taken from trail cameras confirming the presence of Formosan sambar deer at lower altitudes at Taroko National Park in eastern Taiwan.
National Park Service officials provided the photographs following the completion of a two-year ecological monitoring program led by Weng Guo-jing (翁國精), head of National Pingtung University of Science and Technology’s Institute of Wildlife Conservation.
One of the photographs shows a Formosan sambar deer foraging for food on a mountain slope 661m above sea level, a report by Weng’s research team said.

It was the first time in 15 years that a Formosan sambar deer was sighted at such a medium-to-low altitude, it said.
Researchers visited the site and verified, through an analysis of animal droppings, that the deer had been in the area.
A native species of Taiwan, the Formosan sambar deer is protected by conservation laws. The animals used to be found in mountain forests at altitudes of 300m to 3,500m. However, due to habitat destruction and poaching, their population declined sharply and their range of activity became limited.
In the past decade or so, they have only been seen at altitudes of more than 2,000m, park officials said.
Even at that height, few people have encountered the deer, and most of those who have seen them are veteran hikers who gave the animal a new name — Taiwan’s “mountain’s deity beast,” they said.
The photographs indicate that the native deer species have expanded their range of activity to the eastern section of Taroko National Park, although their main habitat remains in high-altitude forests, the report said.
The ecological monitoring program covered 22km2 area — two abandoned mining sites Dacingshuei (大清水) and Hueide (匯德), at altitudes of 500m to 1,500m. The team set up six voice recorders and 30 trail cameras that do not interfere with wildlife activities and start recording or taking photographs when they detect animal movement.
The report also recorded the presence of other protected native wildlife, including Berdmore’s ground squirrel, red and white giant flying squirrel and Formosan giant flying squirrel.
At a wildlife protection reserve at Mount Cingshuei, there had been sightings of Pallas’ squirrels, Berdmore’s ground squirrels, and the two types of giant flying squirrels, as well as audio recordings of Formosan samba deer, it said.
Most wildlife in the park have become more active and chances of seeing them are higher from March to May and September to November, officials said.
Results from the monitoring program are to be used as a reference for the conservation and management of these animals, while the public can read the report online on Taroko National Park’s Web site, they said.
LOUD AND PROUD Taiwan might have taken a drubbing against Australia and Japan, but you might not know it from the enthusiasm and numbers of the fans Taiwan might not be expected to win the World Baseball Classic (WBC) but their fans are making their presence felt in Tokyo, with tens of thousands decked out in the team’s blue, blowing horns and singing songs. Taiwanese fans have packed out the Tokyo Dome for all three of their games so far and even threatened to drown out home team supporters when their team played Japan on Friday. They blew trumpets, chanted for their favorite players and had their own cheerleading squad who dance on a stage during the game. The team struggled to match that exuberance on the field, with
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
