Landcover=wood (or the presently OSM popular 'natural=wood')applies to
trees of all types, ages, planting densities and heights.
So there are some sub tags that can be used under that land cover.
Harvesting operations are a function of land use (forestry or farm) and
could be a sub tag under these land uses.
There are some who say that the source tag should not be used, they want
to rely on the changeset comments, these do carry a date.
Personally I prefer using the source tag.

Clifford,
You are correct, landuse is different from landcover.
I assume you are tagging farmland as landuse, not landcover.
The problem with landcover is that the currency and consistency of the
source information is critical and is very difficult in OSM.
The OSM tagging for landcover should have two additional *required*
tags: "source=" and "source:date=" .

This is an interesting discussion. As a tree farmer and
professional forester I am offended by the suggestion that a
harvested area is different landuse from areas that are in
other stages of forest growth.
I understand the need to avoid current logging operations, but
I would say that crowd sourced mapping is not the place to get
that information. There are so many basic features missing
from OSM, spending effort to collect vegetative landcover
seems like a lower need, especially considering the fact that
in a relatively short period of time the vegetative signature
will be different.
Palolo,
Thank you for your input. If I understand you, landuse=forest is
what the land is being used for while landcover is what's there.
To get a Warin's point, if you want to know if the area was
clearcut recently, we should be using landcover.
We do have a lot of features that need added to OSM. But I always
encourage new mappers to map what they like. Currently I have been
adding farmland to my county. It helps tell the counties story.
Farmland is just part of the story, a big part of the county is
also logging. Right now I'm reluctant to just start adding
forested areas until I learn more. Any suggestions on how we
should be mapping forested areas would be appreciated.
Best,
Clifford
