Transplanting<br />

• Transplanting of mature trees, shrubs, sub-shrubs <strong>and</strong> ground-covers<br />

is possible for specific sites or amenity planting.<br />

• Advantages include immediate effect <strong>and</strong> introduction of species not<br />

amenable to other means of propagation.<br />

• Disadvantage is high risk of costly failures.<br />

• Transplanting is generally best carried out in cool, wet conditions.<br />

• Where individual mature trees are required for the rehabilitation<br />

program, transplanting should be completed while suitable<br />

earthmoving <strong>and</strong> lifting equipment is on site.<br />

Aftercare<br />

• Success rate of all methods of planting will be reduced unless<br />

adequate aftercare is provided.<br />

• Staking <strong>and</strong> protection of individual trees is desirable but seldom<br />

practical on a broad scale.<br />

• Perimeter fencing will provide protection from browsing stock,<br />

vehicle <strong>and</strong> pedestrian trafficking. Temporary fences are unlikely to<br />

provide adequate protection for the required period.<br />

• Perimeter fencing which incorporates wind break materials will<br />

increase success of revegetation programs in most circumstances.<br />

• Avoid irrigating seeded areas unless irrigation can be maintained<br />

until reliable rains occur.<br />

• Irrigation of seedlings should be progressively <strong>and</strong> slowly reduced to<br />

prevent over dependence on surface roots.<br />

• Follow-up application of fertilisers, additional seeding or planting may<br />

be required.<br />

• Damage <strong>and</strong> loss by insects <strong>and</strong> vermin are common, particularly<br />

where revegetation programs provide herbage in otherwise sparse<br />

environments.<br />

• Seeding <strong>and</strong> planting should provide for some losses, as application<br />

of insecticides <strong>and</strong> vermin control programs quickly become costly.<br />
