Disturbance
Hydrology: Water diversion (water
eventually returns to site); Other
hydrologic alteration observed--see
Disturbance notes
Soil alteration: Compaction; Displacement
of soil; Erosion (general); Excavation;
Ground disturbance (general); Pedestals or
hummocks (by people or animals); Pipes;
Trails (by people or animals);
Soils
Recreational effects: Tracks or trails by
vehicles (ATV, 4WD, etc);
Animal effects: Feral animals; Grazing or
browsing (by ungulates); Wild animals;
Trails by animals and people; Trampling (by
ungulates, native or nonnative);
The site was underlain by bedrock and
unconsolidated sediment, with no soil
development. Also, the area has been
extensively manipulated and covered
by a road. Therefore, no soil pits were
dug.
Miscellaneous effects: Fire;
Disturbance Notes
Site has been heavily excavated, with
piping. A road runs across the GDE, and it
Structures: Road (includes construction and has been heavily trampled by ungulates.
