Tang's team came to the encounter of three chechiguo leprechaun: Tiger force sin, deer and sheep force force Daisen Daisen.

The monk in mock them a pass after subduing them one by one. Today the story again in China on begun. Photography lovers in pulling out the "week of the Tiger" and get out "Liu antelope": an award-winning photo of Tibetan antelope was identified counterfeiting marks.

In this photo is wait until the night of 8 days 8 to "shoot" in the picture, the prospect is just across the railway bridge of Tibetan antelope, the background is flashed by train.

However, this scenario is party synthesis with two photographs.

Roads are the habits of the "nomadic"

In wildlife, especially a shoe repair, Habitat has been a worldwide problem.

A hoof animals is a kind of animal. In accordance with each leg, the number of hoof-and-mouth animals mainly belong to two categories — perissodactyla and Artiodactyla, including horses, donkeys, rhino, which contains all kinds of cows, deer and antelope. A hoof animals mostly eat grass running workhorse. Due to food in nutrition is very scarce, so have hoof animals require significant Habitat, diet determines they are living a Rove and living the life of "nomadic". When the Habitat being road and rail cut off, they are not "prohibited through" warning signs seriously.

Of course, if you have hoof animals can care issues too big.

However, hoof animals mostly troublemaker. Odd hoof animals are very stubborn, chase the cars is their hobbies, neck and neck down or up, sometimes to a and lane. Last year, few horse Equus in animals through Xinjiang in the nature reserve of 216 Highway Yunming.

Artiodactyla animal guts are generally smaller, but their team generally larger.

A case study in Tibetan antelope, large flocks will exceed 600 only, so a mighty army across the road or rail, is really a big trouble. People see a large group of Tibetan antelope gathered at the roadside, often stopping to watch or whistle, which prevents Tibetan antelope. More troublesome is that most Artiodactyla animal evolution a special eye structures. Their retina has a layer behind a special reflective layer, allowing them to capture the faint light, this is their eyes shining light shining down. When the night the lights shining brightly shining them strong light will let them temporary blindness, in this case, these guys will stop instinctive choice — this usually means that a traffic accident.

Tibetan antelope also "green channel"

Most popular this is plagued by the United States, developed road network, a large number of motor vehicles and relatively good wildlife conservation status and let the United States, particularly those living in the Midwest region of human suffering.

United States Highway Safety Insurance Institute 2004 report noted that today all-year around 150 car accident occurred hit deer, killed hundreds of deer, resulting in more than 200 vehicle occupants were killed.

Construction of the separation barrier is the solution to this problem in the most direct way.

However the most direct and often are not optimal, the cost of the construction of a fence, railing $ 1 km in ten thousand dollars or so, and the isolation barriers hinder these wild animals foraging through the highway or looking for a spouse.

United States company developed a lamp reflector, every 15 meters a reflector to Highway lamp light turned 90 degrees, according to the road on both sides.

When a car passes through, roadside deer will be fixed in advance, "according to the lights." Install the mirror than cheaper construction fence, every 4000-$ 6000 km of cost can also be called. But when the winter snow cover, the mirror will fail.

For the moment, the best solution is to build wildlife corridor.

On the road or railway specific local settings specifically for wildlife passage of culverts or flyover, let wildlife and vehicle prevails. There is no need to worry about these wild animals will not use these channels, Yangzhou University animal behavioral scientists discovered, 2003 also only know through the railway embankment of Tibetan antelope, the next year will generally learned to use the "green channel". "Liu antelope" photos of five North Bridge is the Tibetan antelope are favorite one. Scientists in the month of August 2004 for a month is 125 group of Tibetan antelope from under the bridge. Of course, the premise is that the bridge has not train too!
