Among the causes of their unexpected deaths, roadkill ranks at the top. In Taiwan, the revealed statistics are rather shocking. According to a five-year survey by the Taiwan Roadkill Observation Network (TaiRoN), approximately five million animals become roadkill each year, involving 550 different species. Between 2012 and 2017, it was found that 54 leopard cats, 257 palm civets, and thousands of cats, dogs, and reptiles perished under the rolling wheels of the motor vehicles. TaiRON originated from a Facebook group created by concerned citizens in August, 2011. The group members come from a variety of locations and academic backgrounds rather than from any particular group or association. It is not an intentionally planned, research-oriented citizen science project. Rather, it is gradually established through discussions and consensus among members. There are four tenets guiding this organization: roadkill mitigation, citizen science, environmental education and life cherish. To encourage people’s participation in the program, TaiRON specifies four easy steps as follows: 1 Turn on GPS on your phone and take sharp photos when you encounter dead (wild) animals in the field. boll N ebonobo 、 20 Upload the photos and information (dates, latitude and longitude etc.) to the database and Facebook by APP. 100 robilo 3 Collect the complete carcass carefully with 2 layer zipper bag, label with information, and then put it into solid cardboard boxes or Styrofoam. 4 Use 7-ELEVEN “Frozen Shipping, Home-Delivery" and "C.O.D. (Cash on Delivery)" to send the package to Endemic Species Research Institute. One animal of TaiRON’s survey is the leopard cat. As Taiwan's only surviving wild cat, this feline species faces death threats from habitat loss, pesticides and car traffic, the last of which is the most serious one. Leopard cats are often found struck and dead on the roadside. By publishing roadkill statistics on leopard cats, TaiRON has championed the protection of this endangered species. Due to their unyielding efforts, there has been a significant drop in leopard cat deaths. toitained and odd or how Torloni 第四回 g 41
