Characteristic values determined from wood samples with a moisture content of 12%.
The indigenous Black Alder (Alnus glutinosa) is the predominant species of tree found alongside streams and in riverside woodlands.
Due to its preference for dark, moist locations, folklore attributes something mystical to alder.
The beautiful, reddish-white colour of the wood, its evenness and the ease of working with it, make alder a very popular wood amongst furniture builders.
