Hydrologic recovery is the process by which the hydrologic characteristics of a watershed that has been subject to harvesting are restored to near pre-harvest condition by forest regeneration.
Hydrology
The properties, distribution, and circulation of water and snow.
Hummocking
Formation of raised mounds of soil in wetlands from trampling by large animals.
Highgrading
A partial harvest removing only the most valuable tree species, or trees of desirable size and quality, without regard for the condition of the residual stand.
Higher Level Plan
A resource management plan that establishes the broader, strategic context for operational plans. The objectives determine the mix of forest resources to be managed in a given area.
Herbicide
A chemical that kills or regulates growth of plant species or groups of species.
Herbaceous
Non-woody vegetation, such as grasses, sedges, reeds and forbs.
Helicopter Harvesting
An aerial harvesting system whereby logs are removed vertically from the forest and flown to a roadside landing or drop zone.
Harvesting
The practice of felling and removing trees or the removal of dead or damaged trees from an area.
Harvest Schedule
A document listing the stands to be harvested per year or period, usually showing types and intensities of harvests for each stand, as well as a timetable for regenerating currently non-productive areas.
