Silvicultural Systems Trial


The SST compares different methods for harvesting and regenerating tall wet Eucalypt forests and tracks the development of the regenerating stands over time.

The SST compares several methods of harvesting and regenerating tall, wet eucalypt forest with the standard method of clearfell, burn and sow (CBS). The harvest methods vary in the amount and arrangement of forest / tree retention left within the harvest area. Harvesting treatments were done progressively between 1998-2004.


Scope & Initial Analysis

The SST has been intensively measured to describe aspects of:

  1. the harvesting (cost, safety, productivity, aesthetics)
  2.  the regeneration (stocking, density, growth rates)
  3. elements of the biodiversity (plants, birds, beetles, fungi, bats, lichens and bryophytes)

Regeneration and biodiversity responses are being tracked through time – before harvest, and at varying times after harvest (1, 3 and 10 years so far).

Initial analysis of the results measured at three years after harvest identified aggregated retention as the most prospect alternative to CBS.
