Enviva Wood Supply Map

Choose a supply area to explore harvests Enviva sourced from during the time period spanning October 2016 through March 2017. Hover over points to view harvest details.

Percent Volume to Enviva is marked as “N/A- Thinning” for tracts that underwent a thinning, as this type of harvest is a mid-lifecycle forest management practice in which a small proportion of trees are removed from the forest in order to provide space for the remaining trees to grow into larger, high-quality timber. All wood produced during this type of harvest are low-grade roundwood and/ or other chipped harvest residues.

In order to maintain the privacy of Enviva’s suppliers and landowners, the points are placed in the vicinity of the harvest, but not the precise location of the forest. Due to agreements with a subset of suppliers prohibiting mapped display of harvest information, a small subset of forest tracts (comprising < 2% of total fiber supply) are not displayed on this map. Volume data from these harvests are still included in summary statistics.

Feedstock Origin — Enviva Aggregate1


38% Mixed Pine & Hardwood Forests

Mixed pine and hardwood forests contain both hardwood and pine trees that are primarily grown to produce pine sawtimber. These forests are either manually planted to pine or naturally seeded. Hardwood growth happens naturally through root and seed propagation.

At maturity, the forest contains mostly straight, large-diameter pine trees with smaller, crooked hardwood trees growing underneath. When the forest is harvested, the stems of sawtimber trees are sold to sawmills that make higher-grade solid wood products like lumber. The tops and branches of sawtimber trees and the crooked hardwood trees from below cannot be made into solid wood products, but need to be removed from the forest so the next rotation of pine sawtimber can begin growing. These harvest byproducts are sold to consumers of lower-grade wood like Enviva.

29% Southern Yellow Pine Forests

Southern yellow pine forests contain mostly pine trees that are grown to produce pine sawtimber. These forests are usually planted and managed for increased productivity and to prevent the growth of non-pine species.

These forests are generally ‘thinned’ about halfway through their growth cycle, meaning that some trees are removed to create more room for remaining trees to grow to sawtimber size and quality. These thinned trees are sold to consumers of lower-grade wood like Enviva. When the forest reaches maturity and is harvested, the stems of sawtimber trees are sold to sawmills that make higher-grade solid wood products like lumber. The tops and branches of sawtimber trees and any poor-quality trees that cannot be made into solid wood products are sent to consumers of lower-grade wood like Enviva.

23% Mill & Industry Residues

Mill and industry residues are comprised of sawdust, wood shavings, and other material produced as a waste product during sawmilling and other wood processing.

5% Upland Hardwood Forests

Upland hardwood forests are forests in upland areas containing mostly hardwood trees that are grown to produce hardwood sawtimber.

At maturity, these forests contain mostly large-diameter oak, poplar, and hickory hardwood sawtimber trees with smaller, crooked hardwood trees growing underneath. When the forest is harvested, the stems of sawtimber trees are sold to sawmills that make higher-grade solid wood products like furniture. The tops and branches of sawtimber trees and the crooked hardwood trees from below cannot be made into solid wood products, but need to be removed from the site so the next generation of the forest can begin growing. These harvest byproducts are sold to consumers of lower-grade wood like Enviva.

4% Bottomland Hardwood Forests

Bottomland hardwood forests in lowland areas and floodplains containing mostly large-diameter oak, gum, and cypress sawtimber trees with smaller, crooked hardwood trees growing underneath.

When the forest is harvested, the stems of sawtimber trees are sold to sawmills that make higher-grade solid wood products like furniture. The tops and branches of sawtimber trees and the crooked hardwood trees from below cannot be made into solid wood products, but need to be removed from the site so the next generation of the forest can begin growing. These harvest byproducts are sold to consumer of lower-grade wood like Enviva.

The majority of bottomland hardwood forests are working lands that require active management in order to maintain forest health, but some are sensitive habitats of High Conservation Value (HCV) that should be conserved. Enviva is committed to not taking wood from HCV bottomlands. To learn about how Enviva makes bottomland hardwood forests sourcing decisions, visit our Responsible Wood Supply Program page.

<1% Landscaping and Arboricultural Residues

Landscaping and arboricultural residues include wood derived from landscaping and urban tree maintenance.

1 Enviva idled the Wiggins plant in early 2017. Therefore, the facility’s wood sourcing data are not included in this summary. Including Wiggins’s data does not affect the enterprise-wide feedstock origin summary.
