As one area of their pit or quarry is being extracted, rehabilitation must be completed in the areas where the aggregate reserves have been exhausted. Progressive rehabilitation is beneficial in many ways as it:Rehabilitating Stone Quarries & Aggregate Sites | A.L. Blair,The rehabilitation practices for stone quarries and other aggregate sites has come a long way as the standards for rehabilitation continuously increase and focus more on site-specific ecologies. Rehabilitiation. The main aspect of rehabilitation often involves grading slopes, laying subsoil and topsoil, and planting vegetation. More so than ever, vegetation is being planted that is native to theQuarry rehabilitation : cliffs, landforms and ecology,,Many stone quarries are located in scenic areas of natural beauty and this necessitates the best possible rehabilitation. After the stone has been extracted efforts are made to simulate natural landforms to blend the quarry faces into the surrounding landscape. The resulting naturalized cliffs and the quarry floors offer scenic value and also provide excellent habitats for a variety of,Ecological and Landscape Rehabilitation of a Quarry Site,,The revegetation of steep rock slopes of quarries is a very challenging activity.

In this study, the aim is to investigate the areas with potential risk for jointed karstic limestones in a rock quarry.

Quarry rehabilitation : cliffs, landforms and ecology,

In Ontario, Canada legislation has required rehabilitation of stone faces to be sloped at 2:1 and completely revegetated. In the early 1990's Ontario quarry operators began looking at creating a landform that blends with the landscape and recognizes the ecological value of cliffs. The most critical factors in quarry rehabilitation are planning ahead so the most suitable landform and ecosystems are completedEnvironmental Management Plan Operation of Quarries to,,of steep slopes or close to Leave soil slopes steeper than 10° completely bare and unprotected.

Progressive rehabilitation helps to minimise the visual impact of a quarry and control dust, erosion, and the invasion of weeds. It also assists in fostering good community relations.
