Political/Historical context
• Global Financial Crisis• Australian Government response -Stimulus• Favoured Infrastructure – NCRIS (National
Collaborative Research Infrastructure Scheme)• Research infrastructure – Environmental =
TERN• Not tangible infrastructure eg. Roads, but not
classical research either research – need to deliver Data – Different measures of Success
![Page 4: Morton presentation6](https://reader031.vdocumento.com/reader031/viewer/2022013013/58ecbe4e1a28ab803f8b46e5/html5/thumbnails/4.jpg)
Primarily funded to support / develop ecological research infrastructure
– integrate existing data and make it accessible to the national and global ecosystem sciences community in a
common format; and
– collect new data strategically in areas of high priority to allow subsequent analysis and modeling of the assimilated
data.
In the context of AusPlots the Plots and their associated data are considered to be infrastructure.
TERNthe Terrestrial Ecosystem Research Network

What is TERN?
• A Network of scientists and practitioners collecting and delivering ecological research infrastructure.
• Delivered as a number of facilities:• Auscover: Ecological/ biophysical remote
sensing products• Ausplots: Surveillance monitoring of
Australian ecosystems• ACEAS – A Synthesis facility similar to NCEAS
![Page 6: Morton presentation6](https://reader031.vdocumento.com/reader031/viewer/2022013013/58ecbe4e1a28ab803f8b46e5/html5/thumbnails/6.jpg)
• Coasts: Info in the interface between terrestrial and marine
• Australian Supersite Network (ASN): Highly instrumented study sites.
• Australian Transect Network (ATN): Data and questions on environmental gradients; Space as a proxy for time
• Eco-informatics – Data delivery warehouse; Fully integrated data
• E-Mast – Ecological and biophysical modelling
![Page 7: Morton presentation6](https://reader031.vdocumento.com/reader031/viewer/2022013013/58ecbe4e1a28ab803f8b46e5/html5/thumbnails/7.jpg)
• Long Term Ecological Research Network (LTERN): Brings together scientists working on long term sites – Question based targeted monitoring
• Ozflux: a series of flux towers to understand fluxes between land and atmosphere
• Soil and Landscape Grid: Delivering Australian Soil information in line from plot to continent
• Many facilities collaborate together on aspects of their work.

Monitoring
Logo
There is ongoing tension between different types of monitoring regarding their relative merits.
Often a monitoring program is judged on what would define a successful monitoring program for a different type of
monitoring.
Each type of monitoring needs to be judged against its aims and objectives.
![Page 10: Morton presentation6](https://reader031.vdocumento.com/reader031/viewer/2022013013/58ecbe4e1a28ab803f8b46e5/html5/thumbnails/10.jpg)
Which is better?They all have their Place!
All are needed and provide useful contributions to our knowledge of Australian environments.
Each of these endeavours need to cooperate/ collaborate with the others to provide a holistic solution to monitoring.
The most important parts are actually the
arrows!
![Page 11: Morton presentation6](https://reader031.vdocumento.com/reader031/viewer/2022013013/58ecbe4e1a28ab803f8b46e5/html5/thumbnails/11.jpg)
Surveillance Monitoring• Looks at entire communities ( Is more likely to be concerned with
the trajectory of communities rather than individuals or species)• Versatile and reusable – Useful for many purposes• Drivers unknown (May provide some insight, but that is not the
focus of design)• Broad stakeholder base, given multiple purposes• Detect and quantify change that we don’t know about and weren’t
anticipating • Some hope of method standardisation – If method broad in scope
![Page 12: Morton presentation6](https://reader031.vdocumento.com/reader031/viewer/2022013013/58ecbe4e1a28ab803f8b46e5/html5/thumbnails/12.jpg)
• Likely to be able to adapt to emerging issues – If method broad in scope
• Has focus areas rather than tightly defined questions – it is likely that this information will inform on many questions.
• Aims to detect and quantify environmental change across large geographical areas.
• Less likely for the same sites to be regularly revisited – Longer re-visit time. (Duration of many years)
• More often assessing long term change rather than shorter term dynamics.

Objectives of AusPlotsNational network of surveillance and ecosystem baseline assessment sites
Developing standardised plot assessment methods to be used for measuring and sampling vegetation and soils, and
Developing and implementing a stratification process to decide the locations of plots, which is applicable at a continental scale, and
Establish permanent plot infrastructure throughout Australia where baseline surveys of vegetation and soils will be conducted
by
Implementing the plot assessment methods developed for measuring and sampling vegetation and soils - in the locations decided, and
- analysing the samples collected, and
Storing the data and making it freely availableTo
enable the detection (and trajectory and magnitude) of environmental change across the continent to be determined.

About Our Method
• Practicality/pragmatism has had to prevail
• “It’s not about developing the perfect method, but rather understanding how imperfect the method is.”
Modular Methods• The method has been designed in modules
• Ease of use in the field• For your own purposes (not AusPlots funded) there is the
possibility of only including some modules• For AusPlots and training purposes we will cover all modules

Vouchers for genetic and isotope analysis
1. Take around 10 cm2 from 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
+ Duplicates for Dominant

Assessing Cover above the device
• Uses a densitometer
• Ensure the device is level using the bubble level
• Use the cross hairs and small circle to identify what is intersected.

DBH Calculations
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.
