“The sphagnums are the keystone species in peatland ecosystems, which hold one third of the earth’s organic carbon.”

On July 25, 2025, CER partnered with Anne Arundel County and Underwood & Associates to celebrate International Bog Day! The event took place at Arden Park, located in the Severn River Watershed. An interpretive sign for the Arden/Gumbottom Bog was unveiled at the event. The County preserves its unique bog habitats from disturbance with a model protective overlay zone that protects the bogs’ entire drainage area.
