Gregg’s Pine
Scientific name: Pinus greggii
Overview
Gregg’s Pine is a medium-sized evergreen conifer native to Mexico, where it occurs naturally in scattered populations within the eastern and central mountain ranges. A member of the Pinaceae family, it is adapted to mountainous environments with seasonal rainfall and can tolerate relatively dry conditions. Its naturally fragmented distribution makes it one of the more geographically distinctive Mexican pine species.
The wood is moderately lightweight to medium-weight, resinous, and generally straight-grained, with pale sapwood surrounding yellowish to reddish-brown heartwood. Although Gregg’s Pine is less prominent internationally than many major commercial pines, it is useful for construction, carpentry, furniture components, packaging, pulp, and general woodworking. The species has also attracted considerable interest for plantation forestry because of its growth rate and adaptability.
Quick Facts
- Common Name: Gregg’s Pine
- Scientific Name: Pinus greggii
- Region: Central American Softwoods
- Tree Size: 35–80 ft (10–25 m) tall, 1–2.5 ft (0.3–0.75 m) trunk diameter
- Average Dried Weight: Approximately 34 lbs/ft³ (545 kg/m³)
- Janka Hardness: Reliable species-specific value not widely documented
- Grain: Generally straight
- Texture: Medium to coarse
Identification Characteristics
Gregg’s Pine typically produces pale cream to yellowish sapwood surrounding yellowish-brown to light reddish-brown heartwood. Growth rings are generally visible, producing contrast between lighter earlywood and darker latewood.
The grain is usually straight, although knots and localized irregularities may occur. Its texture is medium to coarse, and natural resin is present throughout the wood, giving it characteristics typical of many Mexican pine species.
Key identification traits include:
- Yellowish-brown to light reddish-brown heartwood
- Pale cream to yellowish sapwood
- Generally straight grain
- Medium to coarse texture
- Visible growth rings
- Noticeable earlywood and latewood contrast
- Moderately resinous character
Working Properties
Gregg’s Pine generally machines easily with both hand and power tools. Straight-grained material cuts, planes, and shapes readily, while knots may require additional care. Resin can accumulate on cutting edges and machinery during extended machining.
The wood sands well and accepts paints, stains, and clear finishes. Resinous surfaces may require additional preparation before gluing or finishing.
- Machines easily with sharp tools
- Cuts and planes readily
- Sands to a smooth surface
- Glues well with proper preparation
- Accepts paints, stains, and clear finishes
- Good fastener holding characteristics
- Resin may accumulate on cutting tools
Safety Note
Pine wood dust and natural resins may cause skin, eye, or respiratory irritation in sensitive individuals. Appropriate dust collection, eye protection, and respiratory protection are recommended during machining and sanding.
Common Uses
Its useful strength-to-weight ratio, workability, and suitability for plantation production make Gregg’s Pine suitable for numerous woodworking applications, including:
- Construction lumber
- Carpentry
- Furniture components
- Interior joinery
- Panel products
- Packaging
- Crates
- Pulp and paper
- Utility woodworking
- General woodworking
Sustainability & Notes
Gregg’s Pine has a naturally fragmented distribution within Mexico, with populations occurring in separated mountain regions. This geographic separation has contributed to variation among natural populations and makes conservation of native genetic diversity particularly important.
The species has also received attention for plantation forestry both within Mexico and internationally. Its relatively rapid growth and ability to perform under a range of environmental conditions can make it useful for timber and pulp production.
Responsible plantation establishment and management should consider water resources, soil conditions, biodiversity, wildfire risk, and the conservation of naturally occurring populations.

Collector Notes
Gregg’s Pine is an excellent collector species because it represents one of Mexico’s lesser-known native pines and has a naturally fragmented geographic distribution. Authenticated wood specimens are considerably less familiar than samples of major commercial pine species. Displaying Gregg’s Pine alongside Patula Pine, Montezuma Pine, Smooth-Bark Mexican Pine, and Ocote Pine provides an excellent representation of Mexico’s exceptional Pinus diversity and makes the species particularly worthwhile in a comprehensive conifer collection.
