Haunted Hills (HH)

A study of the land in the Catchment of Gippsland Lakes - Vol 2 - land system Haunted Hills- geoArea: 29 sq. km (0.2%)

This land system occurs on Tertiary deposits uplifted with the South Victorian Uplands and the Yallourn Monocline movements. It is deeply dissected and elevation and relief are higher than in many other areas of Tertiary materials. The terrain consists of very high hills or low mountains, typically with a ridge-and-ravine topography and sometimes with very steep slopes, such as in the Yallourn North and Kornalla areas. Some broad ridge crests and less-steep slopes do occur.

The soil parent materials, which range from gravelly deposits to clays, have been variably modified by weathering processes. All the soils observed have deep clayey subsoils and leached acidic profiles. The upper horizons are commonly loamy or sandy. In places the subsoils and underlying layers are highly dispersive and tend to become fluid when wet. They are susceptible to gullying and slumping.

The vegetation is mainly open forest II with open forest III in drainage gullies and ravines.

Variable; depending on local parent material— commonly gradational and duplex profiles, mainly with yellowish brown, less frequently with reddish brown, clay subsoil; moderately to strongly acid. May contain gravel

Incidence with components
    Alteration of vegetation:

    — reduction in leaf area, rooting depth and/or perenniality
    Reduced transpiration,
    resulting in:

    a) increased deep

    b) increased regolith

    Uncommon: but common in specific areas of component 3

    Removal of trees

    Usually after the removal of trees from steeper land

    Increased movement of water to groundwater; increased base-flow of streams

    Increased sediment load
