Landscape

An area of interacting and interconnected patterns of habitats (ecosystems) that are repeated because of the geology, landform, soil, climate, biota, and human influences throughout the area. A landscape is composed of watersheds and smaller ecosystems.

Landscape characteristics

The distribution and representation of ecoregions and elevational classes; the size of relatively large and intact habitat areas, and their adjacency to protected habitats; the effects of lands with protected or conservation status on landscape fragmentation; and the relationship between landscape and disturbance patterns.

Late Forest Succession

The stage of forest succession in which most of the trees are mature or overmature.

Leasable Minerals

Minerals such as coal, oil shale, oil and gas, phosphate, potash, sodium, geothermal resources, and all other minerals that may be acquired under the Mineral Leasing Act of 1920, as amended.

Life Zone

Areas or "belts" of land that have distinct plant and animal characteristics determined by elevation, latitude and climate. When ascending a high mountain you will pass through these life zones. Examples of life zones include the Upper Sonoran, where Cedar City is located and gramma grasses, sagebrush, and scattered pinyon juniper predominate, and the Transition zone, where Ponderosa pine is predominant.

Litter (forest litter)

The freshly fallen or only slightly decomposed plant material on the forest floor. This layer includes foliage, bark fragments, twigs, flowers, and fruit.

Local roads

Classified roads that connect terminal activities (e.g., trail head, log landing, camping site) to collector and arterial roads. They are constructed to meet the access requirements of a specific resource activity rather than for travel efficiency. When not in use for the activity for which they were constructed, local roads may be used for other purposes. They are often closed to restrict motor use. The construction standards for these roads are determined by the requirements necessary for the specific resource activity.

Locatable Minerals

A mineral subject to location under the 1872 mining laws. Examples of such minerals would be gold, silver, copper, and lead as compared to oil and natural gas which are leasable minerals.

Logging Residue (Slash)

The residue left on the ground after timber cutting. It includes un-utilized logs, uprooted stumps, broken branches, bark, and leaves. Certain amounts of slash provide important ecosystem roles, such as soil protection, nutrient cycling, and wildlife habitat.
