Catholic Church in Greenland first churches in the western hemisphere, and after much effort the people of Greenland received a bishop. The church thrived with the Norse colony which saw its peak in the 14th century, and had an active relationship with Scandinavia and the European continent; the church also participated in the European exploration of the Americas. The abandonment of the colony around 1450 ended any church presence in Greenland and the Protestant Reformation in Denmark effectively shut Greenland from any Catholic presence until the 20th century, when freedom of religion was declared and a small permanent Catholic presence reestablished. Catholicism was introduced

The most common tree native to Greenland is the European white birch ("Betula pubescens") along with gray-leaf willow ("Salix glauca"), rowans ("Sorbus aucuparia"), common junipers ("Juniperus communis") and other smaller trees, mainly willows. Greenland's flora comprises about 500 species of higher plants, i.e. flowering plants, ferns, horsetails and lycopodiophyta.
