Review of strategic seed reserves
To estimate the amount of seed required to fulfil
3 year plan requirements and compare that with
present seed centre stocks. This will provide
seed coordinators with a priority list for seed
collection.
Provided on-going analysis of seed stock shortfalls and surpluses on an
as-needs basis.
L Clark
Support for seed allocation program
To ensure that optimum seed mixes are used in
all FT sowing.
Developed germination testing database as part of seed management
system.
Provided technical advice and support to seed centre staff on germination
testing procedures.
Supported seed allocation process for 2010 sowing.
2.3.2 Special species
Ensure an ongoing long term
supply of special timbers

Remedial treatments in swamp-blackwood
forests
To regenerate CH042B, a failed swamp
blackwood coupe. The coupe was rough heaped,
burnt in autumn 2009, re-fenced and sown.
Monitoring of the coupe continues and regeneration has improved.
The coupe is due for its 3-year regeneration survey next year.

Regeneration strategies for swamp blackwood
myrtle forests
To investigate the effectiveness of partial
harvesting and fencing in achieving successful
regeneration in swamp blackwood myrtle forests
(CH41D and E), harvested in 2008 and 2009, and
burnt in autumn 2009.
This coupe continues to progress well. The browsing control (fencing and
trapping/shooting inside the fence) was expensive but is still proving to be
very effective. Many of the blackwood seedlings are over 1 metre tall, and
due to the retained partial canopy, there was no frost damage at all to the
blackwoods, when a neighbouring clearfell suffered quite badly.
