Sacred groves are places where there are anywhere from a few trees to several acres of forest or natural vegetation dedicated to local folk deities or tree spirits. They are usually established or controlled by local communities or villages. There are three types of sacred groves formed by past communities: traditional sacred groves, temple groves, and groves around burial or cremation sites. Traditional sacred groves are built with religious meanings and functions. They are usually considered to be the places where the village deity lives and protects the community. And in another way, the community is responsible for taking control of its sacred groves and protecting its uses; for example, the program of sacrifices. Because of this relationship, traditional sacred groves had once spread widely across many regions of Africa. People established many sacred groves outside all settlements. The Osun-Osgogbo sacred grove in Nigeria is one of the best representatives of the sacred groves. It is the last remnant of primary forest left in southern Nigeria. And it is also one of the largest sacred groves that have survived to the present day. Due to its magnificent importance and traditional cultural value, Osun-Osgogbo was inscribed in the list of UNESCO World Heritage Sites in 2005. The Yoruba Goddess of Gertility is the deity believed in by the people of Osun. More than four centuries ago, they began to build the sacred grove and continued to maintain it. Not only is the place well preserved, but also the culture is passed on from generation to generation. Even now, the traditional residents of Osun-Osgogbo hold a grand celebration called Osun-Osgogbo festival every year in August. Attracting hundreds and thousands of Osun worshipers, the story… middle of the paper… taboos and constraints passed down through oral history. They have such great value in historical and religious studies, and people take great care to protect and maintain them. Local sacred groves are usually controlled locally by small, flexible companies. Management is simple and effective. At the same time, community members protect and care for the grove by virtue of their religious beliefs. Furthermore, the protection of sacred sites and natural resources are inseparable. Furthermore, community rules have preserved an intact forest. For example, in some sacred groves you may not touch dry foliage or fallen fruit, you may collect dead wood or dry leaves (but cutting live trees or branches is not permitted), and hunting and logging are generally strictly prohibited. Based on all these protections by individuals and societies, frightened woodlands should be protected greatly.
