The present invention relates to an eco-friendly ecology block for providing a refuge and a pathway of aquatic animals and terrestrial animals from predators, and, more specifically, to an eco-friendly ecology block which is installed in the water of a river, lake, reservoir, dam, sea or the like for protecting native fish from introduced fish species such as bass and bluegill, increasing the number of native fish, and for preserving and recovering the river ecosystem, and which is installed on land such as the shore of a river, reservoir, dam, an inclined plane of a seawall, a roadside or the like for protecting amphibians, reptiles, rodents, and small mammals living in a waterside from predators, in particular humans, increasing the number of the animals, and recovering the natural ecosystem. The eco-friendly ecology block of the present invention comprises: a first main frame with a first hiding place formed by a space formed as the bottom surface is inserted into the inside for an animal to enter the first hiding place through a hole placed on the outer circumferential surface and primarily escape from a predator; a second main frame combined with the first main frame to alternate with each other in all directions with a second hiding place with a separate space blocked from the outside formed as the bottom surface is inserted into the inside; and an entrance for connecting the first hiding place and the second hiding place for enabling the animal which has primarily taken refuge in the first hiding place to secondarily take refuge in the second hiding place nearby escaping from the predator which has entered the first hiding place.;COPYRIGHT KIPO 2015
