Stand level Biodiversity

2. The answer is ….. 53

3. Trivia 5% of all reserves were floaters
37% were internal (58% on the edge)
20% of blocks had Vets – of those ~ 32 Vets per block
69% of patches <2ha (31% bigger)

6. CWD Sampling Accuracy
McCrae et al; (1979) (from Van Wagner – Practical Aspects of the Line Intersect Method) recommended 90 m. CWD line transect per 20 ha. (4.5m/ha.)
From 2005 sampling:
21,840 m/6,916 ha gross area ~ 3.2 m/ha

7. Tree Sampling Accuracy

9. Estimating within plots
precision and accuracy of estimating heights and diameters?
Review of Q/A data – comparison of measured to estimated heights

11. Vision enough cutblocks sampled in a landscape unit
baseline data for each subzone variant in the LU
landscape level biodiversity assessment complete
Representation, interior habitat, road density…
..celebrate
species work
Probably need a couple of years of sampling before this occurs – 30 per district? 10 per landscape unit? Until then should only assess individual cutblocks.
To fully assess a unit:
need full set of baseline data – (data in each harvested subzone)
need assessment of landscape level biodiversity – likely indicators
representation by variant in managed and permanently unmanaged state,
interior habitat of permanently unmanaged
patch and age class distribution
road density and distribution
species (at risk) states and trends

12. Continuous Improvement
Why does the assessment ask for a Professional Opinion?
Indicators used are surrogates.
Compared to Baselines.
Humans are great integrators and ecological systems are varied.
Ultimately your opinion is a check against how the model scores the cutblock.

13. Continuous Improvement
Should we have the assessor answer a series of questions?
Does the retention represent the pre harvest stand?
Yes No If no what is different?
Does the retention capture rare elements?
Yes No If no what elements are missing?
Has the retention been distributed through the cutblock in a way that will benefit wildlife?
Yes No explain?

14. Continuous Improvement

15. Continuous Improvement
What are Innovative Forest Practices?
Innovation – Something newly introduced, a new method, device.

16. Continuous Improvement
Has the licensee used a practice not normally seen in the district that may be beneficial to biodiversity? Yes No If yes describe….
Could create a list… but
Is stubbing innovative? Used quite widely in areas of the interior… but might be an innovation on the coast.
Fungal inoculation… Innovation… Yes… but unless you have the prescription or the block has a sign up will be difficult to know.
Cavity creation…. Has been tried but not implemented widely… would fit the innovative practice.

17. Continuous Improvement
Volume Calculation –
Evaluation – focused on structural attributes that we believe are reasonable indicators of “Biodiversity”
Premise – If you maintain the range of structural attributes you will lifeboat species through the next rotation.
Emphasis not on volume but quality of structures… legacies… number of large tall dead trees etc.

18. Continuous Improvement

19. Ecological anchors What are they?
Plot based assessment of rare elements (you don’t find them)
statistically viable way to assess rare elements (i.e. cluster sampling)

20. Time on block versus accuracy
Dispersed retention and importance of stratification .
Small patches - how many 0.1 ha patches do we need to sample anyway?
Should we keep track of time and manpower spent on block?

21. Proposal for card changes

22. SLBD data Continuous Improvement
Map with plot numbers noted
Patches on map – no form B
Edge patch on map – not in gross

23. Reserve summary covers complete block
Separate reserve summaries – no lumping

24. Unique (simple) reserve ID for each area
Commercial thinning – DT
No more DU (DO will do)
If any RRZ/RMZ call it PR or DR

25. Missing heights (but only 4%)
Creative tree species (not too bad)
Missing header info (where does this plot belong?)

26. Please list trees on stand table (rather than comments)
Try to avoid the multi-card stand tables

27. Check your logic – a WT class 1, 50 cm dbh pine – 5 metres tall?
There was one mirage plot! (OK – no more)
