Forestland management units Land Management unit Description
Forest district (region) • Regional forest surface with own management for the purposes of silvicultural operations and harvest operations
Example High Atlas (Morroco)
Forestland management units
Land Management unit
Surface and scale
Forest district (region) • Surface: > 104 ha • Topographic Scale:
• < 1/100.000
Example High Atlas (Morroco)
Forest Tagargoust
Forest Toufliht
Land Management unit
Description
Forest • A plant association, predominantly of trees or other woody vegetation, defined by property and/or topographic features such as uplands, plateaus, valleys
• A Forest may contain 100 or more stands
Forest Tagargoust
Forest Toufliht
Land Management unit
Surface and scale
Forest • Surface: [100 - 104 ha] • Scale : [+/- 1:10.000]
Land Management unit
Description
Stand • An aggregation of trees or other growth occupying a specific area and sufficiently uniform in species composition, size, age, arrangement, and condition as to be distinguished from the forest or other growth on adjoining areas.

Land Management unit
Description
Stand • The composition, structure and ecological functions within a stand are similar enough that a forest use prescription can be applied uniformly within the stand

• Normally a stand will be studied or managed as a single unit.
Stand typing: Description and delimitation of forest areas that have similar conditions with respect to tree size, species mix, structure and age.

• Improve forest health • Protect against wildfires • Provide and improve wildlife habitat • Develop ponds or other water sources • Learn about or study nature • Establish new tree plantings • Enhance tree growth and quality in your forest • Hunting or fishing • Generate income from harvesting timber • Generate income from non-timber products • Generate income from recreational access and use • etc

• To promote and maintain desired landscape conditions • To maintain and develop naturally reproducing forest communities • To provide economic and social benefits through a sustained yield of
forest products • To determine appropriate, sustainable timber harvest levels. • To demonstrate and promote silvicultural practices that sustain ecological
and economic forest values http://www.apps.dcnr.state.pa.us/forestry/sfrmp/silviculture.htm#guidelines
