How Do You Read a Code for Forestry in Rev. 5?

In ISIC Rev. 5, published by the UN Statistics Division, a forestry code is read hierarchically from the general to the specific. Section A places the activity in primary production from land and water. Within Section A, the forestry area separates tree growing and forest management from farming and fishing. Detailed headings then separate silviculture, logging, gathering of wild forest products, and support services.

What does the section letter tell you first?

Section A is the broad home, and a forestry code starts there, in primary production from land and water. That single letter already rules out large parts of the classification. The work is not manufacturing, even when it ends with timber products, and it is not trade, even when timber is sold. It is primary work: growing, harvesting, or gathering from forests. Everything after the letter refines that starting point, stage by stage, and a reader who keeps the starting point in mind is less likely to drift into a sawmill heading when the work in question is still in the woods.

How do you separate forestry from farming and fishing?

Within Section A, the forestry area narrows the activity to trees and forests. That sounds obvious, but it does real work. A holding that grows crops and manages woodland does two kinds of primary production, and the forestry area isolates the tree side of that holding for separate attention. Similarly, a business that fishes and also owns forest must not let the fishing side colour the forestry reading. Area first, detail second: that order keeps unlike work apart.

Once inside the forestry area, the next separation is between stages. Silviculture and logging differ because growing a forest and felling it are different stages of production, separated by decades. Gathering wild products and providing forestry support are further distinct activities within the same area, each with its own daily pattern. A reader who lumps all four together as “forestry” has not yet finished reading the code. The detailed headings exist precisely to pull them apart.

Logging or silviculture: a worked contrast

A code for logging describes felling and primary roundwood production: trees brought down, cut into lengths, and moved to a first collection point. A code for silviculture describes growing and tending the forest that will later be logged: planting, thinning, and managing the stand through its long rotation. The two codes describe opposite ends of the same forest’s life, and confusing them would mix investment years with harvest years in the statistics.

Picture a single stand over time. In its early years, crews plant and thin, and the work is silviculture. Decades later, a different crew fells the mature trees, and the work is logging. The forest did not change its identity. The stage changed, and the heading changes with the stage. A business that does both, across different stands at different ages, needs its main work identified before a headline heading can be chosen, and the fuller record can still show the other stage.

Where do gathering and support sit in the reading?

Gathering comes next in the reader’s mental checklist. Does the business take wild forest products, such as mushrooms or resins collected in forests, as its main work? If so, its heading sits with gathering, not with growing or felling, even though the work happens in the same woods. Support comes after that: is the business paid on a fee basis to help a forest owner or logger, planting, thinning, or harvesting for someone else? If so, its work is a service to forestry, and its heading reflects that service relationship rather than ownership of the timber.

How large is the structure you are reading within?

For reading a code for forestry, Rev. 5 published by the UN Statistics Division contains 22 sections from A to V, 87 divisions, 258 groups, and 463 classes in total, and it was endorsed by the UN Statistical Commission in March 2023. Those totals explain why a single section guide can only give the shape of an area. The detail sits in the UNSD structure itself, where each class description adds limits and inclusions that a short guide must leave out. Readers who need an exact heading should work through that structure step by step, rather than stopping at the section summary given here.

To check a heading, start with the UNSD classification detail and the Rev. 5 publication listed in the frontmatter of this guide, then look for the heading whose description matches the work described here. If the work is part of a formal record, take the next step to the national statistical institute or business register that holds that record, because national guidance may add local examples and notes. Keep the revision noted for reading a code for forestry, since Rev. 5 and Rev. 4 headings can differ even where an activity name looks familiar.

This guide explains the reading order only, and it assigns no code to any forest business. It is statistical information only, and it does not determine any reader’s code, principal activity, or registration; confirmation for a real case rests with the national statistical institute or business register that holds the record.
