has been a highly controversial form of logging in Australian forests, in part because of its impacts on values such as biodiversity conservation.
One consequence of clearfelling
in the river catchment areas is the alternation of floods and droughts, both caused by the soil's inability to retain water once the forests are gone: water from the monsoon rains rushes into the river valleys with great force, causing devatating floods, but after the passage of the monsoon the rivers dry up because the catchment soil has not conserved water to release gradually.
One primary reason for the loss of large old trees is that large areas of old growth have been converted into young regrowth because of widespread selective logging followed by four decades (since the 1970s) of intensive clearfelling

Just like conventional clearfelling
, salvage logging can result in the depletion or loss of these habitats, with flow-on negative effects on the biota that depend on them.

Backed by 16 environment groups, the blueprint's major selling point is that it will create three times the number of jobs in Tasmania that it will jeopardise through protecting the forests from clearfelling
Similarly, Cunningham and Smith (1961) showed that 36% of the original surface soil organic matter could be lost within 2 years after clearfelling
natural tropical forest if soil was left bare.
Environmental reaction, fuelled in many countries by the clearfelling
of native forests (the north-west USA and Tasmania are used as examples), led to pressure to protect the remaining native forests.
In one stretch we drove from Wynard to Yolla and the amount of clearfelling
in progress or that had been completed was vast and extended for miles.
The Greens have criticised our central highlands experiment because it involves traditional logging practices like clearfelling
