Forestry practices, best to worst

Anyone who reads a building or a roll of paper labelled “FSC certified” and shrugs has earned the right; we are about to defend that label, with caveats. Anyone who has ever stood on the edge of a 100-hectare clearcut in the rain has also earned the right to be angry about forestry; we are about to defend the rage. Both reactions are reasonable, and neither is the full picture.

Globally, humans use about 4 billion cubic metres of wood a year. About half of that goes to fuel and the other half to industrial uses — lumber, panels, paper, packaging^[1]. The forest area that produces this is large, but it is not infinite, and the methods used to produce it differ by orders of magnitude in their ecological impact. The intent of this primer is to walk those methods from best to worst, name the trade-offs honestly, and name the institutions doing the work to keep practice honest.

1. Indigenous-led forest management

Forest land managed by Indigenous communities, under recognised tenure, with traditional governance, consistently outperforms most other tenure types on every metric researchers measure: lower deforestation rate, lower fire incidence, higher carbon stocks, more biodiversity, and often, surprisingly, higher direct economic return per hectare on a multi-decade horizon^[2]. The pattern shows up in Brazilian Amazonia, Mesoamerican mosaic forest, the Canadian boreal, and the BC coastal rainforest.

Two structural features explain most of the outperformance. First, the planning horizon is longer than any commercial rotation cycle — most Indigenous tenure systems treat the forest as a multigenerational shared inheritance, which makes “cut now and let the next generation regrow it” structurally unappealing. Second, the harvest practices, where harvest happens, are typically selective, light-touch, low-machine-impact, and embedded in a broader land-use framework that includes hunting, fishing, food gathering, and ceremony. Damage to the soil and to non-target species is far below industrial-forestry baselines.

The Coastal First Nations of British Columbia and the Tla-o-qui-aht Tribal Parks Guardians on the west coast of Vancouver Island are well-documented working examples^[2][8]. The federal Indigenous Guardians programme in Canada is funded specifically to scale this kind of stewardship^[3]. Where governments have been willing to recognise tenure, the outcomes are unusually good. Where they have not been, the same forests usually deteriorate.

2. Continuous-cover, selective harvest in mixed natural forest

Selective harvest — sometimes called continuous-cover forestry, single-tree selection, or group selection — takes individual trees out of a stand on a long cycle, leaving most of the stand intact at any given time. It is the dominant approach in much of central Europe (Germany, Slovenia, parts of Switzerland), in some of Atlantic Canada, and in any operation that has prioritised the structural and biodiversity values of mixed-age forest over short-rotation yield.

Done with care — low-impact equipment, narrow extraction corridors, retention of standing dead and downed wood, no whole-tree removal — selective harvest can preserve most of the structural indicators of mature forest, including a substantial fraction of the mycorrhizal community^[4]. It does not produce the same volume per hectare per year as a short-rotation plantation. It does produce wood the rest of human civilisation continues to need, on land that remains a real forest the day after harvest.

The honest caveat: this is harder, slower, and more expensive than industrial methods, and it is not appropriate to every site or species. It works best on long-lived shade-tolerant species (beech, fir, hemlock, sugar maple) and worst on shade-intolerant pioneers (Douglas-fir at certain elevations, several pines). Anyone selling “all forestry should be selective” as a universal slogan is over-claiming.

3. FSC-certified mixed forestry on naturally regenerated forest

The Forest Stewardship Council’s Principles & Criteria are a third-party international standard for responsible forest management^[5]. They cover legal compliance, worker rights, indigenous and community rights, environmental impact, monitoring, and high-conservation-value forest. The Programme for the Endorsement of Forest Certification (PEFC) is a parallel system that endorses national standards meeting comparable criteria^[6].

An FSC-certified operation on naturally regenerated forest, with retained habitat trees, intact riparian buffers, no chemicals, and recognised indigenous consultation, is a genuinely good thing. It is not the same as old growth. It is not the same as zero impact. But it is meaningfully better than uncertified industrial harvest, and the difference is independently audited.

The honest caveats are well known to anyone in the field. Certification does not always catch “laundering” of timber from non-certified or illegally cleared land into certified supply chains. The standards have evolved unevenly across regions. Some certified operations are still far from optimal, and some non-certified operations are quite good. The label is a strong signal, not a guarantee, and it is best read as “significantly less likely to be doing harm” rather than “harmless.”

4. Plantations on previously cleared agricultural or degraded land

A plantation — even-aged, sometimes single-species, often non-native — on land that was already cleared for agriculture and has now been converted back to growing trees is a complicated category. It can be a real win: the alternative was annual cropping or pasture, and the plantation produces wood (substituting for harvest from native forest) plus modest carbon storage plus some habitat.

Where this category goes wrong is when it is allowed to count as “reforestation” in a way that displaces or distracts from protecting actual primary forest. The Forest Stewardship Council’s standards distinguish between plantation and natural-forest harvest for exactly this reason^[5]. The IPCC mitigation chapter is explicit that monoculture plantations are not a substitute for protecting old-growth carbon stocks — the carbon density and the ecosystem function are simply not the same^[7].

Read claims about “trees planted” with this in mind. A plantation on an existing pasture, well-managed, is fine. A plantation on land that was, until recently, primary forest, is the opposite of fine.

5. Industrial monoculture plantation, short-rotation

Single-species, even-aged stands harvested on rotations of 20–30 years (or shorter) are the workhorse of global pulp and paper production. Eucalyptus in Brazil and Iberia, southern yellow pine in the U.S. southeast, radiata pine in New Zealand and Chile, oil palm encroaching into former forest in Southeast Asia.

Honestly assessed, this category is a mixed bag. The pulp and paper most readers use comes mostly from this category. The carbon stored on a 25-year-rotation pulpwood plantation is a fraction of what the same land would store under mature mixed forest. Soil fertility erodes over multiple rotations unless heavily fertilised. Biodiversity is low at every rotation point. Water-use can be high enough to draw down regional groundwater.

The plantation itself is rarely the central scandal. The central scandal, when there is one, is usually where the plantation was established. Eucalyptus on long-degraded farmland in northern Portugal: defensible. Eucalyptus on cleared Atlantic Forest in Brazil: not defensible. Oil palm on cleared peatland forest in Indonesia: actively destructive.

6. Industrial clear-cutting of natural forest

Whole-stand clear-cutting of natural — especially mature or primary — forest, with stumps removed, slash burned, and replant rows running over the remaining soil, is the practice that most directly destroys the structural and biological value of forest. It is the practice where the gap between “wood produced” and “forest still functioning as forest” opens up to its widest. It is also still legal in many jurisdictions, including parts of Canada, the United States, Russia, and Brazil.

Most of the “cancel forestry entirely” rage that lay readers feel comes from images of this practice in mature forest. That rage is reasonable. The corrective is not to abolish forestry; it is to retire this method on natural forest and require the harvest categories above instead. The European Union’s Deforestation Regulation (EUDR), passed in 2023, is a partial step in that direction at the import-supply-chain level — it requires due-diligence statements that products imported into the EU were not produced on land deforested after 2020^[7]. It is not perfect, and its implementation has been bumpy, but it is the most concrete example of policy moving against the bottom of this list.

7. Illegal logging

The bottom of the list is unregulated, undocumented harvest in defiance of national or local law. Illegal logging accounts for an estimated 15–30% of global wood production and a far higher share in the most-affected tropical countries^[1]. It typically involves no consideration for soil, watershed, or species; ignores indigenous tenure entirely; supports trafficking and corruption; and is the proximate cause of much of the worst tropical deforestation.

This is a hard category for an individual reader to act against directly. It is fought primarily through enforcement, customs interception, supply-chain transparency, and the satellite-based monitoring that organisations like Global Forest Watch produce daily^[8]. Refusing to buy products from supply chains with no traceability is a small but real contribution.

What an honest reader should take away

Three things, mostly:

Forestry done well, on the right site, with the right oversight, is part of how we should keep using wood. The world will continue to need lumber, paper, and biomass; pretending otherwise is wishful. The question is whether we get it from #1, #2, or #3 above — or from #5, #6, or #7. The answer is mostly a function of certification, regulation, and tenure, all of which are political-economic levers more than technical ones.

Old growth is not in this list because old growth is not in the harvest economy. Mature primary forest should be subtracted from the working-land conversation entirely. Every tonne of carbon, every species niche, and every century of fungal community in old growth is more valuable left standing than it is as boards.

Foresters are not villains. Most foresters working on natural forest land want to do this well; the constraints they operate under are usually set above their pay grade by regulation and by the markets buying their wood. Respecting the profession is part of how we move the practice up the list, not down.
