–ensure large enough sample (to cover an A3 sheet of paper)
–flowering/fruiting, bark where possible –root for grasses + leaves (use an envelope for easily lost bits)
1.Attach barcode (well) to non-diagnostic part of the sample
2.Scan barcode in Vouchering module
3.Provide a field name
•either a good guess at taxonomic name OR
•a descriptive name that is only current for that site
4.Place in plastic bag
Use a small amount of this material for genetic sample ( as discussed in the genetic section)
Method: Vegetation DNA Samples& Leaf Isotope Analysis
•phylogenetic diversity and endemism
•the reason that the teabag needs to be synthetic
•accurate info on carbon and nitrogen content of the leaves
•can inform on plant stress, adaption to climate change, assist with modelling etc.
Sampling from voucher specimens
1. Take around 10cm2from each voucher specimen
2. Place into a synthetic tea bag and seal
3. Label with adhesive voucher label and scan with app
4. Place bag in box with ⅓ cup silica granules (self indicating and non-indicating granules)
5. Seal box and ensure it is labelled with plot identifier. Preferably 1 box per plot.
Change silica every few days until indicator no longer changes colour.
6. Samples can then be used for isotope and DNA analyses
Sampling from dominant perennial species
For each dominant perennial species in the plot (i.e. FPC >2% or opaque canopy cover >5%) Additional leaf samples should be taken from four individuals across the plot
1. Take around 5cm2from each of four individuals
2. Place into a synthetic tea bag and seal
4. Place in sealed box as before
5. These samples will be used for DNA analyses only.
3. Label with adhesive voucher label and scan with app (to link to voucher specimen and plot)
Scrape loose material from soil surface
Use a trowel or small shovel to take a sample from the soil surface
Ensuring that the trowel is not contaminated with soil from another site.
Do include surface crust occurring at the site –max depth 3cm.
Place the sample in a calico bag and label with a barcode
Scan the barcode using the app.
Tie the calico bag and place in a labelled plastic bag that contains 1/3 of a cup of silica that contains some indicator silica
Seal the bag
Replace the silica until the indicator no longer changes colour
Place the 9 plastic bags from the one site into a large calico bag and label for that site.
•Improve our understanding of fauna:
•Provide a baseline against which future change can be assessed
•Build understanding of the relationship between habitat dynamics and faunal species population dynamics
•Lead to efficiencies in biodiversity monitoring
Fauna Protocol Broad Aims
Rationale for Fauna Protocol
•No existing standardisednational fauna monitoring method
•High level of interest in establishing ‘biodiversity monitoring’ in rangelands
•Complement the existing AusPlotsRangelands Survey Protocols Manual
•Refine details of the purpose
•Who will be doing the surveys?
•Trapping –types, duration, effort, timing
•Collation and review of methods currently (and previously undertaken)
•Review of agency requirements (legislative)
•Consult with experts -state agencies, researchers and universities, museums, NRM groups and (reserve) landholders
•Draft the method selection
•Development of the survey protocols manual
•Release on the website
•…. then what?

Basal Area from Photopoints…..
Ways it is currently obtained
An Alternative: A New Photopoint methodPhoto Layout
•24mm Focal Length
•Aperture = F11
•Raw Format (+/-JPG)
•1.3m to centre of lens
•Calibration target used
•DGPS Location recorded
A New Photopoint methodThe Tripod
Tripod and Star Picket setup
If terrain not flat then attempt to copy the average slope.
The Scene Reconstruction Process
IdentifesLike features in images pairs
Uses this to calculate camera location
Using Camera location information projects information into 3d space
Trunks then identified Spectrally, but including 3D information
A Cylinder is fitted to each trunk
The Cylinder is cut at 1.3m (DBH) and the area of the cross section is calculated (DBH for the individual tree)
These DBH’s are then summed for the whole site.
Currently hasa max depth of view, but improvements being worked on.
Trunk Identification and Basal area calculation
Take account of Occlusion
Trial and accuracy assess in a variety of ecosystems
Determine method variation needed for different environments
Automate processing (Work Commenced)
