A New German Benchmark for Tree Crown Support

摘要

Anew version of the German technical best practices for Tree Care Operations (ZTV Baumpflege) was released in January 2006 by the Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau e.V. (FLL, in English The Landscape Research, Development &Construction Society). This organization is similar to TCIA, PLANET and/or the ISA in the U.S., developing best practices in the "green" industry, including the arboricultural profession.
