Picea morrisonicola Hayata 1908

The largest wood disc collection in the museum belongs to endemic Picea morrisonicola and it originated from the Tataka around 2600 m above sea level. It was more than 430 years old at the time of its collection. The detailed texture of the tree rings indicating the growth rhythm affected by environmental changes is a record of Taiwan’s natural history between the 16th and 20th centuries. The width and morphology of tree rings implies the variation of precipitation. It precisely recorded the environmental changes as an important evidence for the study of ancient climate.
