Forest Nurseries and Gathering of Forest Products (NAICS 11321): An Investor's Primer

1. Overview

NAICS 11321 is a NAICS industry (a five-digit code in the North American Industry Classification System, the government's business-category scheme) inside the Agriculture, Forestry, Fishing and Hunting sector. It covers two very different activities under one federal code: forest nurseries that grow tree seedlings — mostly pine — for replanting logged, burned, or storm-damaged land; and the gathering of forest products, meaning goods harvested from standing forests without cutting the timber (pine straw, wild ginseng root, moss, bark, cones, sap, and the like) [1].

Because this level contains only one child industry, everything below is a compact roll-up. For the full treatment — company-by-company detail, pricing, regulation, and the investment case — read the 113210 primer. This page states what the level is, gives its own federal figures, and points you to the child for depth.

2. What's inside — and why this level equals its one child

NAICS is a nested hierarchy: each five-digit NAICS industry breaks into one or more six-digit national industries. NAICS 11321 is a rare case where the split does nothing — it contains a single national industry:

  • 113210 — Forest Nurseries and Gathering of Forest Products.

The five-digit and six-digit codes have identical scope, identical definitions, and identical statistics [1]. So "11321" and "113210" describe the same set of businesses; the child is simply the same industry written to full six-digit precision. That is why this page is short and hands off to the child primer rather than repeating it.

3. Size

Our ground-truth federal figures (U.S. Census Bureau, County Business Patterns 2023) [2]:

  • Employer establishments: 185
  • Paid employees: 932
  • Annual payroll: $57.4 million (First-quarter payroll: $13.5 million)
  • Derived average: about 5 employees per establishment (932 ÷ 185)
  • U.S. Small Business Administration (SBA) small-business size standard: $20.5 million in average annual receipts [5]

Because the level equals its one child, these are also the child's figures. Our data contain no industry revenue, profit, seedling-production value, or nonemployer receipts — payroll is not sales, and we do not estimate the missing values here.

Undercount caveat — read this. County Business Patterns (CBP) counts only private employer firms with paid employees in this exact code. Three large pieces of the industry sit outside that count: government nurseries (the 38 state and territorial nurseries alone grew about 123 million seedlings in 2022, plus federal and tribal nurseries) [4]; captive nurseries run by big timber companies for their own replanting (their staff roll up under the parent's forestry code); and individual gatherers — ginseng diggers and pine-straw rakers, who are mostly seasonal non-employer sole proprietors tracked separately in Nonemployer Statistics [13]. The physical scale tells the truer story: U.S. forest nurseries produced more than 1.27 billion tree seedlings for the 2023 planting season, about 82% of it planted in the South [3]. A headline of 932 employees sits underneath an operation that plants well over a billion trees a year.

4. Investable universe

All value concentrates in this level's one child, and it splits the same way. There is no U.S.-listed pure-play forest-nursery stock whose financials isolate the industry; public exposure is indirect:

  • Timberland real estate investment trusts (REITs) — Weyerhaeuser (NYSE: WY) and Rayonier (NYSE: RYN, merged with PotlatchDeltic Jan 30, 2026) — own forest land and run captive nurseries as an internal support function, not a disclosed profit line [7][8].
  • ArborGen Holdings (NZX: ARB, New Zealand Exchange) is the closest listed pure play — the largest commercial ("merchant") seedling supplier in the U.S. South, roughly 27% of that market — but a foreign-listed, illiquid micro-cap [6].

Most real activity is private or public-sector: family timber companies, institutional timberland investment management organizations (TIMOs), 38 state and territorial nurseries plus U.S. Forest Service and tribal nurseries [4], and — on the gathering side — thousands of individual harvesters. See the 113210 primer for the full company table and TIMO list.

5. How the money works

Two economic models, both inherited whole from the child:

  • Nurseries are a volume business with thin per-unit margins and long-lived assets. Seedlings sell by the thousand; owners earn the spread between price and the cost to grow (land, seed, labor, fertilizer, irrigation, freight) across enormous volume. The crown-jewel asset is the multi-year seed orchard behind improved genetics — a real barrier to entry. Demand is downstream-linked: you replant what gets harvested, so it tracks timber, lumber, and housing.
  • Gathering is low-capital, seasonal cash income. Pine straw earns a landowner roughly $50–$125 per acre per year for raking rights — a way to earn income from a pine stand between harvests — and is about a $200-million-a-year mulch business in the Southeast [11]. Wild ginseng root is a supply-constrained, export-driven niche [12].

6. Demand drivers

  • Timber harvest and the housing cycle — replanting volume follows how much forest is cut, making nurseries cyclical.
  • The federal reforestation backlog — the U.S. Forest Service has flagged more than 4 million acres (~2.3 billion trees) potentially needing replanting; the 2021 REPLANT Act freed up roughly $123 million a year for national-forest replanting [9].
  • Disaster restoration and climate adaptation — wildfire, hurricane, and pest damage generate year-round replanting.
  • Carbon and afforestation — corporate net-zero commitments fund net-new planting, subject to credit prices and verification.
  • A widely cited 2021 study concluded the U.S. would need to roughly double nursery output to over 3 billion seedlings a year by 2040 to meet reforestation potential — the structural bull case [10]. Judgment: that is a projection, not booked orders; real demand stays uneven because funding, seed, labor, and harvest decisions do not move together.

7. Regulation

Regulation is the child's, unchanged: wild ginseng is listed under CITES (the Convention on International Trade in Endangered Species) Appendix II, with state seasons and U.S. Fish and Wildlife Service export certification [12]; nursery shipments face plant-health inspection and quarantine under the USDA's Animal and Plant Health Inspection Service (APHIS); pesticide and seasonal-worker safety fall under the Environmental Protection Agency's (EPA) Worker Protection Standard; the Lacey Act governs import traceability; and commercial gathering on National Forest land requires permits [1][12]. State seed-source, water, and forest-practice rules vary widely. See 113210 for detail.

8. Consolidation

The industry is split competitively. Seedling production is regional and moderately concentrated — seedlings must match local climate, genetics, and planting windows, and decades-long seed orchards protect incumbents (ArborGen is the dominant merchant supplier in the South) [6]. Gathering is highly fragmented — thousands of individual rakers and diggers, no meaningful consolidation. Most visible consolidation is in the adjacent timberland-ownership layer (the January 2026 Rayonier–PotlatchDeltic merger) [8], which matters because large integrated landowners internalize their own seedling supply. No reliable current concentration ratio exists for this code, and our federal data do not support calling the operating niche either highly consolidated or unconsolidated.

9. Risks

Same risk set as the child, in brief: cyclicality (demand tethered to timber and housing); biology and weather (drought, freeze, disease, or poor seed viability can write off a perishable, seasonal crop); policy dependence (REPLANT funding is a budget decision) [9]; labor and input costs (reliance on seasonal H-2A guest-worker labor); scale limits (multi-year seed-orchard lead times); import competition (Canadian container seedlings); gathering-specific ginseng overharvest and CITES tightening [12]; and disclosure/liquidity — public companies bundle nursery activity into timberlands, and private nurseries and land carry long holding periods.

10. How to invest & outlook

Because the level equals its one child, the how-to-invest menu is identical. Public-market routes: timberland REITs (WY, RYN) for diversified forest-land exposure with the nursery as an internal support function [7][8], or the speculative, hard-to-access ArborGen micro-cap (NZX: ARB) as the only near-pure play [6]. Private-market routes (often the better fit): own or operate a nursery, lease pine-straw raking rights, forest-farm ginseng, or invest in timberland through TIMOs and natural-capital/carbon funds that internalize replanting.

Judgment (outlook). The structural case is a large, partly funded reforestation backlog plus carbon demand set against a nursery system credible studies say must roughly double by 2040 [9][10] — a genuine multi-year tailwind. The near-term reality is lumpier: replanting still swings with the housing and lumber cycle, the policy upside depends on federal budgets holding, and capacity can't scale quickly. For most investors this remains a theme played indirectly through timberland; private investors can capture more of the operating economics but must accept greater illiquidity.
