of young trees
Rabbits, hares, deer, kangaroos and wallabies
are common browsers of young trees. Domestic stock can also
be a serious problem if poorly controlled. Where permissible
and appropriate, options for browsing control might include:
shooting and poisoning
The option chosen will depend on the type(s) of browser, the
area, risks and the landowners resources.
Insect damage to young trees can be extensive, especially during
dry periods or droughts, or when insect pest populations are
high. Landowners should be aware of the risks and watch for
signs of excessive defoliation. Small trees can tolerate quite
high levels of defoliation providing the apical bud is not damaged.
But treatment might be needed if trees are attacked repeatedly.
In areas where the risk of insect damage is known to be high,
a one-off application of systemic insecticide may be necessary
when seedlings are planted. As with weed protection, newly planted
seedlings that receive adequate weed protection, and grow to
a height of one metre, will be strong enough to survive after
their first full growing season.
Frosts, hot winds, sand blasting and hail can destroy young
trees. Guards are often used to reduce these risks although
effective frost control is difficult. Landowners need to assess
the risks and decide whether control is necessary or cost-effective.
