- Forest patch
- • Definition: For the purpose of INFORMA project, a FOREST PATCH (FP)
refers to a forest area that is a candidate for inclusion, or that has been
included, in the INFORMA Forest Management Platform. A forest patch,
preferably larger than 50 ha, can consist of several forest stands of
different age classes, and thus of different forest developmental stages,
but under the same forest management regime. Furthermore, it is
homogeneous in terms of species composition and site conditions.

smallest silvicultural or management entity. Forest stands are the
measurement unit for modelling in INFORMA context and will
preferably have an extent of more than 1 ha, if possible, but in any case,
more than 0,25 ha

- Managed forest
- • Definition: In INFORMA, a forest area is considered as MANAGED FOREST (MF) when a certain silvicultural regime is applied to the area, including some recurrent management interventions such as planting, thinning or harvesting. Also, extensively managed systems with thinning frequencies of less than once per decade in older stands are considered managed. Alternative management activities, like grazing/pasturage or NTFP harvesting, should also be considered.

- Unmanaged forest
- • Definition: In INFORMA a forest area is considered as an UNMANAGED
FOREST (UF) when preferably at least 50 (but depending on the region
20) years of zero-management has been applied. Unmanaged forests
may include primary forests, unmanaged forest reserves, unmanaged
forests after conversion or transition from other land uses (e.g.
agriculture), or abandonment (i.e. non-management) of forest after a
large disturbance event such as wildfires or windstorms or other
socioeconomical drivers.
• Categorization: In INFORMA, unmanaged forests are subdivided into
four categories:
a) Primary forest: a naturally regenerated forest of native species that has
been left unmanaged for long periods of time (at least 100 years), and
that shows no indications of human-induced disturbance or
management (wood harvesting, including firewood, grazing/pasturage
and non-timber forest products (NTFP) harvesting or collecting) and the
ecological processes are not significantly disturbed.
b) Unmanaged reserve: This category includes previously managed forests,
often old-growth forests, where management was discontinued by any
active decision or socioeconomic reasons.
c) Unmanaged after disturbance: a forest that regenerated after a large
disturbance event and where no management interventions have been
performed since the disturbance.
d) Abandoned non-forest land: this category includes spontaneous forest
development after another land use was phased out, such as agriculture
or grazing.
In fact, categories a and b represent together late-successional unmanaged forests,
while the categories c and d form together early-successional unmanaged forests
