Denison 019D – initial planning
• The coupe is located in the Huon River catchment
• Initial survey showed one stream and soils formed in dolerite (low erodibility)
• It appeared to be a straightforward regrowth coupe with few issues
DN019D

January 2005:• Sandstone and
siltstone were dominant, not dolerite
• 2 eagle nests present• Two additional class 4
streams• Steam winch
Field checks
April 2005: another visit with FPA Ecologist, to check nest activity
Plus a later visit to formulate special values prescriptions

Summary of special value issues requiring attention
Fauna• Wedge-tailed eagles• Mt Mangana Stag Beetle• Ombrastacoides denisoni
(little Denison crayfish)

Eagle nests required a minimum of 10 ha reserves

Soil and Water• Soil erodibility was
moderate, not low (dolerite had limited extent)
• Erosion in streams –required extra streamside reserves
• Snowy River Trout Farm downstream –needed extra protection for water quality
• Daves Creek not mapped in right position

Cultural heritage• Steam winch site
required protection

Decisions
• Plan changed from conversion to plantation to native forest regeneration, to reduce risks on water quality for salmon farm
• Sectional harvest planned – leaving reserves around streams and the eagle nest and the steam winch
• Correct course of Daves Creek mapped on ground with new streamside reserve on it
• Revised plan send to FPA specialists for endorsement

Modified plan• Extra streamside
reserves on eroding streams
• Harvest in 3 sections A, B, C
• New section added to make harvest viable (D)
• Eagle nest reserves defined
• Regeneration burning to be in stages

Discussion• Harvest of section D was deferred• The four-month development of the Forest Practices
Plan demonstrates how biological and physical values constrain final coupe shape
• The value of consultation with specialists and interested parties was highlighted
• Final harvest area was 58 ha (smallest section 3 ha, largest 32 ha)
• Coupe management (particularly fire management) was made more difficult and expensive because of sectional harvest (perimeter of coupe doubled)
