Estimate the standing timber value on your woodlot by species, diameter class, stand density, and intended use. Get board foot volume, stumpage value range, firewood cord equivalent, and annual sustainable harvest figures. These are rough planning estimates only — always hire a registered forester before selling timber.
Estimating what your woodlot is worth starts with a timber cruise — a systematic inventory of tree species, diameter, height, and defect across sample plots in your stand. From that data, a forester calculates the total volume in board feet (for saw logs), cords (for pulpwood and firewood), or tons (for biomass). Volume times the current stumpage price equals your estimated timber value.
Board feet are the standard volume measurement for saw logs. One board foot is a piece of lumber 1 inch thick, 12 inches wide, and 12 inches long. Sawmill buyers and loggers quote standing timber prices in MBF — thousands of board feet. Common volume tables like the Doyle or Scribner rule are used to convert tree diameter and merchantable height into estimated board foot yield.
Cords measure stacked round wood volume for pulpwood and firewood. One standard cord is a 4×4×8 foot stack (128 cubic feet). As a rough rule, 1 cord of hardwood equals about 500 board feet of saw log volume, though the conversion varies by species and tree form. Tons are used in biomass and chip markets, where payment is based on green weight at the landing.
Stumpage value is what you receive as the timber owner — the price per MBF or per cord that a logging contractor pays you for the right to harvest the trees standing in the woods. It is well below the retail lumber price because the logger must cover harvesting costs, transportation, and profit. Saw log stumpage reflects only merchantable logs that meet minimum diameter and length standards for lumber production. Standing timber value (the gross total) and stumpage value differ because appraised value may include timber not yet ready to sell or species not currently in demand.
Grade logs vs. pulpwood: Not all trees in a stand are worth saw log money. Straight, defect-free trees with good form are grade logs; bent, forked, rotten, or small-diameter trees are pulpwood or biomass at a fraction of the price. In a typical mixed hardwood stand, 30–60% of volume may qualify as saw logs, with the rest going to lower-value products.
Sustainable harvest rates: A healthy woodlot typically grows 3–5% of its standing volume per year in net annual increment. Harvesting 5–10% of standing volume on a staggered schedule provides sustained yield — you remove no more than the stand grows over a rotation, keeping your timber asset intact for future harvests. Clearcutting or high-grading (removing only the best trees) destroys the long-term value of the stand and is widely discouraged by professional foresters.
Why you need a professional timber cruise: Stumpage prices shift with lumber markets, mill capacity, and regional demand. A registered forester (RF) or consulting forester knows your local buyers, can negotiate sale contracts, and will mark trees to protect residual stand quality. Their fee — typically $10–$30 per acre for a cruise — is almost always recovered through better pricing and avoided mistakes in a timber sale.
Board foot yield per acre varies enormously with tree size. Small-diameter trees (8–12" DBH) typically yield 200–500 BF per acre in a normally stocked stand. Medium trees (12–16" DBH) produce 500–1,500 BF per acre. Large trees (16–20" DBH) and prime veneer-size timber (20"+ DBH) can yield 1,500–5,000+ BF per acre depending on species, height, and stand density. These estimates assume merchantable height of 1–2 logs (16–32 feet); tall, clear-boled timber yields significantly more.
Stumpage is the price a timber buyer pays you for trees standing in the woods, before any harvesting takes place. The buyer assumes all logging costs and risk. Stumpage is quoted per MBF (thousand board feet) for saw logs or per cord for pulpwood. To estimate your total stumpage value, multiply your cruise volume (in MBF) by the current stumpage price for your species and log grade. Walnut stumpage currently ranges from $300–$1,000+ per MBF in most of the Midwest; white and red oak runs $100–$400 per MBF; pine softwood fetches $50–$150 per MBF; and yellow poplar and mixed hardwoods typically bring $60–$200 per MBF. These are rough national averages — local prices can be dramatically higher or lower. Your state forestry agency or a consulting forester can give you current regional stumpage reports.
Timber readiness depends on species maturity, diameter, and your management goals. A commonly used rule of thumb for hardwoods is 16–18 inches DBH for saw log maturity, though walnut is often harvested at 14" and white oak at 18"+ for best grade. From a financial standpoint, timber is ready when its annual value growth rate falls below what you could earn by selling and reinvesting the proceeds — a calculation a consulting forester can model for you. From a stand management standpoint, a timber sale is often triggered by crowding, mortality risk (storm, disease, insects), or the need to release younger age classes. Single-tree selection harvests every 10–20 years keep a stand in continuous production without clearcutting.
A timber cruise is a systematic field inventory where a forester walks a grid of sample plots — typically every chain (66 feet) to every few chains, depending on cruise intensity — and records species, DBH, merchantable height, and defect for each tree above a minimum diameter. The data is then expanded statistically to estimate total volume across the stand. A 100% cruise (every tree counted) is the most accurate but expensive; a 10–20% sample cruise is standard for most timber sales. Consulting forester fees range from $10–$30 per acre for a cruise and sale administration, with many foresters working on a percentage of the sale value. For a 40-acre woodlot, expect to pay $400–$1,200 for a professional cruise — money well spent before signing any logging contract.
Technically yes, but it is strongly discouraged unless you have forestry training. Landowners who sell timber without professional guidance consistently receive 20–40% less than market value because they cannot accurately estimate volumes, do not know current mill prices, and cannot evaluate competing bids. More damaging is high-grading — where loggers take only the best trees and leave slash and damaged residuals — which can reduce your stand's future value by 50% or more. A consulting forester marks crop trees for protection, writes enforceable sale contracts, supervises harvest operations, and ensures logging roads and stream crossings are properly built to protect your property. Their involvement pays for itself on essentially every sale above 10 acres.
