A national monitoring system
For public conservation lands:
1. National and regional reporting of status and trend in
ecological integrity
2. Evaluating the effectiveness of conservation management
and policy
3. Informing prioritisation for resource allocation
4. An early-warning system
Evaluating ecological integrity
Indigenous dominance
‘Are the ecological processes natural?’
Species occupancy
‘Are the species present what you would expect naturally?’
Ecosystem representation
‘Are the full range of ecosystems protected somewhere?’
Biodiversity measures
Vegetation
1. Distribution and abundance of exotic weeds considered
a threat
2. Size-class structure of canopy dominants
3. Representation of plant functional types
Animals
1. Distribution and abundance of exotic pests considered a
threat
2. Assemblages of widespread animal species – Birds
Sampling framework
• 8 x 8 km grid
Standardised field surveys
• Vegetation
• Mammal pests
• Birds
5-year rotating-panel design
• Unique subset of locations sampled
each year
Building trustworthy biodiversity measures
A proof-of-concept using birds

Occupancy: Uses and abuses
Andrew Gormley
Landcare Research
What is occupancy?
• Occupancy is a robust measure of distribution of plants
or animals in the landscape
• Key indicator of ecological integrity
• Metrics:
1. Probability that a site is occupied
2. Proportion of area occupied (PAO)
Presence-only data
• Locations of species
– Specimens, sightings etc

• Draw a shape around points to

• No estimate of uncertainty

Presence-absence data

•
Sample proportion of possible sites

Occupancy = proportion of sites that are occupied

Measuring occupancy
• Can stratify by land cover or other covariates
I. roseii at 89% of forest and 56% of non-forest sites
Forest:
Present in 8 out of 9
Occ. = 0.89
Pasture:
Present in 5 out of 9
Occ. = 0.56
Issue 1: Imperfect detection
• Species is present but you miss it
– Detections might be related to habitat/landcover
Forest:
Present in 8
Observed in 3
Pasture:
Present in 5
Observed in 4

– Brown Kiwi in 26: occupancy = 0.43
Issue 5: Data Quality
• Species is misidentified
• How to assess quality of the record?
• Reliability of observers
Issue 6: What is a presence?
• What constitutes a positive detection?
– Specimen?
– Sighting?
– Sound?
• Other species…
– Poo?
– Sign?
– Remote sensing?

Have to document how raw data is summarised for analysis
Distribution vs Abundance
Distribution is better!
• Estimating abundance is too
hard and/or expensive
– Easier to detect species rather
than count individuals
Distribution vs Abundance
Distribution is better!
• Estimating abundance is too
hard and/or expensive
– Easier to detect species rather
than count individuals
• Distribution is a good
surrogate for abundance
2010
– As a population increases, so
does its distribution
2013
Distribution vs Abundance
Abundance is better!
• Distribution does not provide
enough detail
• Abundance may change with
no change in distribution
– Species is widespread and then
has localised increases in
population
– Species goes into decline but
remains widespread
• Distribution will not detect this
Standardising and mobilising data
Nick Spencer
Goal: solutions for standardisation and mobilisationideally through e-federation of distribution data;
What are the barriers to delivering this?
