Qualitative Habitat Evaluation Index

RIPARIAN ZONE AND BANK EROSION METRIC:

Refers to the quality of the land which buffers the stream from human development. The riparian zone runs from the edge of the water to some artificial structure (roads, fences, housing, etc.), and the quality of the riparian zone includes the nature of the floodplain vegetation.


FLOODPLAIN QUALITY (Past 100 Foot Riparian)

The most predominant land cover or use(s) in the area outside of the riparian zone or in the zone more than 100 feet from stream.






FOREST/ SWAMP/ WOODS [3]

Natural or managed forest, woodland, or swamp.

Floodplain Quality



SHRUB OR OLD FIELD [2]

Shrubs include small trees and shrubs. Most shrublands are managed. Old fields are agricultural fields or pastureland which have been abandoned and which have begun to revert to their natural state.

Floodplain Quality



RESIDENTIAL / PARK OR NEW FIELD [1]

Residential areas include suburban developments characterized by lawns and landscape planting. Parks include city or town parks or similar areas (e.g. golf courses, cemeteries, etc.). New fields are agricultural fields which have been abandoned but which have not yet begun to revert to their natural state.

Floodplain Quality



CONSERVATION TILLAGE / FENCED PASTURE [1]

Conservation tillage is a form of active agriculture in which fields are not plowed, but are rather treated with herbicides to kill previous years' growth and replanted with minimal disruption of the soil. Fenced Pasture includes pastureland in which the animals are kept from the river by a fence.

Floodplain Quality



URBAN OR INDUSTRIAL [0]

This category includes urban and industrial development without lawns or landscape planting, where all materials which are deposited on the ground can be expected to end up in the stream.

Floodplain Quality



OPEN PASTURE/ ROW CROPS[0]

Open pasture includes those pastures in which animals are not restrained by a fence, so that they can come right up to the stream. Row crops represent agriculture in which the field is plowed and conventional agricultural technology is used.

Floodplain Quality



MINING/ CONSTRUCTION [0]

This category includes mines, construction sites, and other locations in which the surface has been disrupted greatly and left in a form in which significant erosion is very likely.
