Increment Hammers
Increment hammers are forestry tools used for a quick examination of recent tree growth. They take a small sample from a standing tree, allowing the user to review growth information without removing a larger core or cutting the tree down.
This type of tool can be useful for foresters, arborists, land managers, estate teams and researchers carrying out repeat tree inspections. It supports practical field records where users need to compare recent growth between trees, sample areas or inspection periods.

Increment Hammers for Recent Tree Growth Assessment
An increment hammer is designed to help users check recent growth in a standing tree. The instrument is inserted into the trunk to take a narrow sample, which is then removed and read using the scale in the handle.
This gives the user a quick way to review recent annual growth without taking a longer core sample. It can be useful when assessing groups of trees, comparing growth across an area or building records for woodland management work.
An increment hammer is not intended to provide a complete assessment of tree condition. It is one tool for gathering growth information, which may be reviewed alongside diameter, bark, height, location and site observations.
What Is an Increment Hammer?
An increment hammer is a compact sampling tool for examining recent tree growth. It has a hollow bit that enters the tree trunk and removes a small sample. The sample is then ejected and read against the scale in the handle.
The tool is intended for quick field use where users need to assess recent growth rather than review a long sequence of growth rings. This can make it useful during repeat woodland inspections, estate checks and forestry surveys.
For more detailed tree core sampling and wider growth-ring review, browse our Increment Borers range. An increment borer removes a longer core from the tree, while an increment hammer is intended for a quicker check of recent growth.
Benefits of Checking Recent Tree Growth
Recent growth information can help users compare trees within the same woodland area or assess whether growth appears to have changed between inspection periods. This may support practical forestry records, woodland planning and routine monitoring.
For example, a forestry team may review recent growth across a sample area to compare trees growing under similar conditions. An estate manager may use repeat checks to build a clearer picture of how selected trees are developing over time.
The reading should be treated as part of a wider assessment process. Tree species, ground conditions, competition from surrounding vegetation, weather patterns and management activity can all affect growth. Clear records help users review results in context rather than relying on a single sample alone.
How an Increment Hammer Supports Forestry Records
An increment hammer can support a more organised field-recording process when the user notes the same information for each tree. This may include tree species, inspection date, sample location on the trunk, recent growth reading and general site observations.
Trunk diameter can also provide useful context during repeat inspections. For tools used to check the outside diameter of standing trees, logs and round timber, explore our Calipers range.
Bark thickness is another separate measurement that may be relevant in some forestry records. For equipment designed to measure the outer bark layer, browse our Bark Gauges range.
Direct field tapes can also support plot checks, trunk measurements and other site records. For related tools, visit our Measuring range.
Using Growth Information for Repeat Tree Inspections
Growth information is most useful when users can return to the same trees or sample areas later. Marking trees, plot boundaries or sample points can make repeat inspections easier and reduce the risk of recording information against the wrong tree.
For flagging tape, markers and related field-identification equipment, browse our Marking range.
Location records may also help where work is spread across larger woodland, estate or land-management sites. GPS-based equipment can support users who need to record positions, return to sampled trees and organise field information by location. For related tools, browse our GPS / GIS range.
By combining growth readings with diameter, bark, location and site records, teams can build a more useful history for each area under review.
Choosing an Increment Hammer for Forestry Work
When choosing an increment hammer, consider the type of tree assessment being carried out and whether recent-growth checks are needed as part of repeat forestry records. This tool is suited to users who need a quick sample for review in the field.
The hollow bit takes a narrow sample from the tree, while the replaceable ejector helps remove it for reading. Routine care and correct handling are important to help keep the equipment working properly between inspections.
Users should also consider whether a more detailed sampling method is required. An increment hammer is suitable for examining recent growth, while longer core sampling may require a different tool. Review the product details carefully before buying to confirm suitability for the intended field task.
