WHAT IS REVEGETATION AND WHY IS IT IMPORTANT?

• Revegetation is the planting of trees and shrubs to increase the ecology of an area.

• There are many different species of native plants that can be planted depending on the area to be revegetated.

• Deep rooted plants hold the soil together and lower the water tables.

• By planting banks and rows of hardy native trees and shrubs, stock and native wildlife can benefit greatly.

BENEFITS OF REVEGETATION

Page 4: Revegetation - Keeping farmland productive for future generations by Ayla Webster

NATURE CONSERVATION AND ENVIRONMENTAL BENEFITS

• Nature conservation benefits include habitat for native wildlife, a diversity of native plants, wildlife corridors, conservation of endangered wildlife and stability for natural ecosystems.

• Growing plants absorb carbon dioxide and give out oxygen.

• Grass grows better in shaded areas as there is better ecology in the soil.

ECONOMIC BENEFITS

• Economical benefits include: shelter for stock and crops, honey, timber, fence posts, cut flowers, fodder, habitat for pest controlling wildlife and erosion and salinity control.

• Some trees may be used as extra feed in a drought.

• Other benefits include aesthetics and preservation of the uniqueness of rural areas.

BENEFITS FOR STOCK

Page 7: Revegetation - Keeping farmland productive for future generations by Ayla Webster

SHADE AND SHELTER

• Shade reduces dehydration and deaths from stress after shearing and transporting or mustering on a hot day.

• Trees and shrubby bushes provide a rain and windbreak to protect stock during storms.

• Shelter can provide protection from hypothermia after shearing

BENEFITS FOR EROSION

HOLDS SOIL TOGETHER

• Roots and humus provide a network to hold soil together. They also provide small channels for water to soak into the soil.

• Dead leaves, flowers and bark decompose to form humus.

• Humus is taken into the soil by worms and is natures’ water crystals, helping to increase water retention in the soil.

SALINITY

Page 11: Revegetation - Keeping farmland productive for future generations by Ayla Webster

INCREASES SOIL PROFILE

• Planting deep rooted trees will reduce salinity by increasing soil levels with roots and humus.

• Decomposing plant matter helps water retention and topsoil profile.

• By increasing soil levels you will lower water table levels, eliminating the evaporation of ground water therefore reducing salt left in the soil.

BENEFITS FOR CROPS

NATURAL PEST CONTROL

• Some revegetative plants attract beneficial insects and native animals that control pest species on crops.

• By increasing native animals and insects that eat pests, pesticide use can be cut down considerably.

• By doing this, you will also save money on chemicals and labour.

BENEFITS FOR NATIVE WILDLIFE

Page 15: Revegetation - Keeping farmland productive for future generations by Ayla Webster

PROVIDES HABITATS

• Many beneficial native wildlife species are becoming endangered due to habitat loss

• Revegetation provides habitats for many different native wildlife species.

• It also provides safe corridors for the movement of wildlife around the farm and between national parks, keeping it off roads.

TYPES OF VEGETATIVE PLANTS

Page 17: Revegetation - Keeping farmland productive for future generations by Ayla Webster

TYPES OF PLANTS TO PLANT

• Plant hardy native species that don’t need much water or any maintenance.

• Indigenous species that are naturally occurring in your specified area are best as they are well adapted to local soils and climatic conditions.

• Strategically place banks and corridors for shade and shelter of stock and crops

HOW CAN YOU REVEGETATE?

GRANTS AND WHERE TO BUY PLANTS

• Many plant nurseries grow plants for revegetation.

• The Catchment Management Authority (CMA) and Landcare offers grants for the revegetation of some farmland.

• Many local councils provide grants for revegetation.
