Enhanced
Biodiversity
It is generally acknowledged that an increase in biodiversity occurs following
planting and natural regeneration of pasture. More particularly, our indigenous
biodiversity, especially birds, are enhanced by the revegetation of pasture
with woody species and the planting of trees, both exotic and indigenous.
Soil Stabilisation
It is well known that the risk of soil erosion, both sheet and mass wasting,
is reduced as a result of tree establishment. The greater soil-holding
capability of trees, particularly indigenous trees, is a simple function
of the greater root strength and greater rooting depth compared to grassland
species.
These soil stabilising benefits are likely to become increasingly important for the New Zealand landscape, the New Zealand economy and the primary sector as the effects of climate change lead to the increased intensity and frequency of extreme weather events.
Improved
Water Quality
Associated with soil stability is the additional benefit of improved water
quality. It is widely recognised that water quality is improved and maintained
by the establishment and careful management of forested catchments.
Aesthetics and Landscape
It is almost without question that humans respond most positively to diversity
in their landscape. New Zealanders and tourists alike expect and need
this diversity in the rural and natural environment and happily, nature
itself seems to have the same preference.
