I keep meaning to post an updated design for the coat of arms, but always find something else getting in the way of it. So for now I have added the official coat of arms from the Reher Community page at http://www.amt-schenefeld.de/.
Official Description: Gold and red divided in a 2:3 ratio. The top displays three side-by-side green, black rooted juniper bushes (which look like romaine lettuce), the bottom a golden border horse.
History of the design: The design of the coat displays features which are characteristic and meaningful to the community of Reher. The three junipers shown in the upper third of the emblem are in reference to the Reher Kratt nature reserve, where there are woody plants such as juniper. The appearance of the border horse symbolizes the significance and importance of many years of trotter horse breeding in the Reher community.
