Mechanische Werkstatt 1 article published in JoVE Environment Advanced Workflow for Taking High-Quality Increment Cores - New Techniques and Devices Holger Gärtner1, Loïc Schneider1, Sandro Lucchinetti2, Paolo Cherubini1 1Forest Dynamics/Dendrosciences, Swiss Federal Research Institute WSL, 2Mechanische Werkstatt, Schenkung Dapples Here, we present a protocol on how to avoid micro cracks in increment cores by applying a cordless drill with a torque multiplier to minimize problems when coring trees, as well as its effect on preparing long micro sections. This protocol also includes a procedure to sharpen corers in the field.
