  text: 'Since the early 2000s, forest owners in Central Europe have increasingly
    planted Nordmann fir (Abies nordmanniana (STEV.) SPACH) and Noble fir (Abies procera
    REHD.) for Christmas trees, intending to convert them into high forests. Climate-related
    damage, especially since 2018, has significantly reduced spruce populations, requirering
    a shift towards climate-adaptable tree species in future forests. Additionally,
    to reduce CO2 emissions from construction, there''s a push for expanding timber
    construction, requiring non-spruce species for load-bearing products and applications.
    Although Nordmann and Noble fir are potential alternatives to spruce, they are
    not yet integrated into European standardization for load-bearing construction.
    Therefore, an assessment of German-origin Nordmann and Noble fir for use in glued
    laminated building products (GLT and CLT) is underway. Kiln-dried lamellas are
    graded visually and by machine using longitudinal vibration, with selected lamellas
    tested for tensile strength. Various mechanical properties are determined using
    non-destructive and destructive methods to establish input parameters for Finite
    Element Analysis (FEA). '
