Austrian Norway spruce provenance test 1978 - Individual tree heights at age of 7 to 15

All measured tree heights (in cm) from the Austrian Norway spruce provenance trial 1978. For details on sites and provenances (i.e., populations) see the other two data files with climate data. The trial sites were measured in 1983 and 1988, at 5 and 10 years after their establishment. This provided height data for the trees at the age of 10 and 15 years. During the 1983 measurement, the shoot length for the preceding three years was also measured, which provided heights for the trees at the age of 7, 8, and 9 years. The trial was established at the Austrian Federal Research and Training Centre for Forests, Natural Hazards and Landscape (BFW) by Dr. K.Holzer. Measurements by former staff at the BFW.

本数据集收录1978年奥地利挪威云杉种源试验中测得的全部树高数据（单位：厘米）。关于试验地点与种源（即种群）的详细信息，请参阅另外两份包含气候数据的数据集文件。该试验林分别于定植后第5年（1983年）与第10年（1988年）完成两次测定，由此获取了试验树木10年生及15年生的树高数据。在1983年的测定工作中，研究人员同时测量了试验树木此前三年的新梢长度，据此推算得到树木7年生、8年生与9年生的树高数据。本试验由K·霍尔泽博士于奥地利森林、自然灾害与景观联邦研究培训中心（BFW）主持建立，相关测定工作由该中心前任工作人员完成。
