Vegetation management
Activities needed to beat back the brush inhibiting seedling growth in clearcuts.
Vegetation type
A plant community with distinguishable characteristics.
Viable population
The number of individuals of a species sufficient to ensure the long-term existence of the species in natural, self-sustaining populations that are adequately distributed throughout their range.
Visual resource
A part of the landscape important for its scenic quality. Managing visual resources is a way to hide deforestation practices from the general public. For instance, when a clearcut is planned, balloons are raised above the trees to see if any part of the clearcut is visible to the general public on well used roads.
