The lynx was chosen to symbolize the wild and rich nature in the rural highlands of the municipality.

Bygland lies in the middle of the Setesdal valley which is also a traditional district in Aust-Agder county.

The valley includes the municipalities of Bykle, Valle, Bygland, Iveland, and Evje og Hornnes.

The Otra river flows from the glacially scoured Hardangervidda plateau in the north, through the Setesdal valley (and through Bygland), and into the sea near the city of Kristiansand.

The majority of the area of the municipality lies in the Setesdalsheiene mountains, at an elevation of over 700 metres (2,300 ft) above sea level.

The municipality stretches from the small town Byglandsfjord in the south to the farms at Langeid in the north.

The municipal council (Kommunestyre) of Bygland is made up of 15 representatives that are elected to four year terms.
