A system assists during execution of a sequence of cuttings in a tree, wherein, during a cutting sequence, a first cut in the tree is followed by a second cut in the tree At least a part of an ideal course of the second cut depends on at least a part of a course of the first cut. An identification device identifies at least the part of the course of the first cut in the tree. A precalculation device precalculates at least the part of the ideal course of the second cut in the tree based on the identified part of the course of the first cut. An output device outputs cutting information for executing the second cut based on the precalculated part of the ideal course of the second cut.

A system assists during felling of a tree. A provision device provides a property of the tree and/or a property of an environment of the tree, identifies at least part of a course of a cut in the tree for felling the tree and/or identifies a position and/or an orientation of a cutting apparatus executing the cut. A determination device obtains felling information related to an ideal felling direction of the tree, compares the identified part of the course to an obtained part of an ideal course of a cut to be executed in the tree for felling the tree in the ideal felling direction, compares the identified position and/or the identified orientation of the cutting apparatus to an obtained ideal position and/or an obtained ideal orientation of the cutting apparatus, and obtains cutting information based on the comparison. An output device outputs the obtained felling information and cutting information.

A method assists during felling of a tree. The method includes the steps of: providing a property of the tree and/or a property of an environment of the tree; obtaining felling information related to an ideal felling direction of the tree based on the provided property; and outputting the obtained felling information.

A timber marking system includes a portable back pack mounted user, the pack carrying a paint storage tank and a pressurized gas tank. The storage tank is pressurized and coupled with a manually operated trigger to allow filed operated timber marking. A method to mark timber includes preparing the tank system with pressurized gas, selectively marking a preidentified tree at the trunk and stump.

Embodiments described herein are directed to an apparatus for determining a direction in which a tree will fall and a method for using the apparatus. The apparatus may comprise a plate including a substantially straight edge suitable for alignment with a vertex formed by a top cut and a bottom cut of a notch cut into a tree and a substantially level bottom surface suitable for stable placement upon the bottom cut of the notch. In some embodiments, the plate may define an internal cavity sized to accommodate a laser light generator. In other embodiments, a rotatable housing including a cavity sized to accommodate a laser light generator may be adjoined to the plate. Embodiments may permit a laser light generator contained within the cavity or the housing to emanate a beam of laser light in a direction that is substantially perpendicular to the substantially straight edge of the plate.
