{DS-ET SYSTEM} We propose a systematic tailored natural channel system suitable for eco-

In order to solve the problem that the road kill reduction effect is extremely low or rather the road kill increases even in the various ecological passway technologies conventionally proposed, the present invention is applied to the ecological passage The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a system for constructing a wild-type animal moving route of an eco-bridge type, a passage-

And a wood inducing fence connected from the road and the railway to the wild animal moving path to induce entry into the wild animal moving path while blocking entrance of wild animals and roads,

In order to provide an ecological aisle system considering the migration route and the habitat environment of wild animals, it is necessary to provide a wild-animal hiding place, a W-Shelter, a S-Shelter ) And a multi-species feeding platform for feeding herbivorous animals, bird feeder, mammals and algae to provide an eco-pathway goal that can significantly improve the prevention of road kill in wild animals And relates to an on-site customized natural passage system suitable for species.

The isolation and fragmentation of ecosystems by human activities such as roads and railroad development activities have caused isolation of habitat habitat, migration between populations, and genetic exchange interception, resulting in the degradation of environmental adaptability of wild animals have.

The disconnection and fragmentation of such ecosystems has frequently resulted in wild animals moving from isolated habitats to feeding and habitat expansion, and road kill on roads frequently occurs on such roads .

Particularly, such road kills often lead to secondary damage caused by the life threat of the driver and the damage of the vehicle and surrounding facilities in addition to the primary problem such as a decrease in the number of wild animals.

To solve these problems, various ecological passage technologies have been proposed in order to induce the movement among the disconnected habitats. Most of the techniques disclosed in the prior art have been field-built without regard to wildlife, which has become obsolete due to poor accessibility or avoidance of access to wildlife.

In addition, this shows that the degree of road keel reduction is insignificant compared to before the installation of the ecological passage, or it causes a serious problem which is rather increased compared to before installation.
