Increment borers should be properly maintained to keep them in good working condition.

Effective use of an increment borer requires specialized training.

Extracting a core from an increment borer, a standard tool used by dendrochronologists.

Age is calculated from an instrument called an increment borer or from planting or harvest records.

Increment borers come in different lengths and diameters and have different types of threads.

An increment borer is a specialized tool used to extract a section of wood tissue from a living tree with relatively minor injury to the tree.

To ease field implementation of phytoscreening, standard methods have been developed to extract a section of the tree trunk for later laboratory analysis, often by using an increment borer.

Increment borer - a device used to retrieve a cylindrical sample of wood material orthogonally from the stem while doing as little damage as possible to the remaining tissues.

Using the increment borer, the US Forest Service located some ancient bristlecone pines at the treeline of the White Mountains of east-central California.

During use the borer should be well lubricated; this makes the auger bit easier to use and helps to prevent the increment borer from becoming stuck in the tree.

The test's hands-on portion includes various tasks such as tree and leaf/needle identification, collecting tree core samples using an Increment borer to determine tree age and historical influences, and Tree planting using proper techniques.

Not many redwoods, or sequoias, exceeded 3000 years but they were generally considered the oldest living matter until the development of the Swedish increment borer enabled dendrologists (people who study the natural history of trees) to age a tree without felling it.

A specimen of this species, nicknamed "Methuselah", located in the Ancient Bristlecone Pine Forest of the White Mountains near Bishop, California, is 4,843 years old (as of 2012), as measured by annual ring count on a small core taken with an increment borer.
