Progeny tests with fir species in Northwest Germany
Mainly since the end of the eighties of the last century, 60 provenance trials with 11 fir species have been established by Lower Saxony and Hesse as a result of the dieback of silver fir. 38 of the trials are still under observation. Based on assessments between age of 13 and 27 years depending on trial, the foreign species are grouped and ranked according to their value for cultivation. Grand fir can be recommended at first.
