2- We need a national framework for our monitoring
to assure data are saved and used to the MAX - The framework should be the most efficient, that
is, provide the most information per dollar spent - The framework should integrate with and
compliment existing monitoring - The framework should represent our best attempt
to satisfy legal requirements
3MSIM Objective
- Nationally consistent protocol to provide
presence data (status) on an extensive array of
vertebrate and plant species and their habitats
across a broad scale in time and space.
4Ancillary Benefits achieved for some species with
high detection rates
- Indications of suitable habitat
- Estimates of abundance
- Measures of reproductive status, age ratios, and
sex ratios for small mammals (based on captures) - Detection of spatially explicit change in
distribution
5Ancillary Benefits cont.
- Information to evaluate existing and
potential indicator species - Provide a foundation for more intensive sampling
and research
6Why sample multiple species?
Synchronous information
7Stellers jay
Northern flicker
American robin
song birds
Goshawk
Spotted Owl
Marten
voles
woodrats
hares
ground squirrels
deer mouse
tree squirrels
chipmunks
8Why use a grid-based approach?
- Stratification by habitat type is not a viable
long-term strategy - Consistency in site location
- Problems with road-based sampling
9Challenges
- Bottom-up vs top-down protocol developmentstandar
dization - Adapt existing monitoring to the new realities
of GIS, spatially explicit landscapes, and a
broad-scale perspective
10By standardizing sampling techniques we can
scale up to answer broad questions.
- Are bird populations declining in riparian zones
of western forests?
- Does thinning have a positive or negative
influence on small mammals?
11MSIM Protocol contributes to research
effectiveness by . . .
- Providing baseline information about communities
and ecosystems

22Integrated Monitoring and Research
MSIM indicate that occupancy and abundance are
associated with prescribed fire
MSIM Data show substantial increase in prairie
dog occupancy and abundance
Research initiated and reveals thresholds of
and effects of prescribed fire
Management adapts to incorporate prescribed fire
and thresholds into management strategy
23MSIM Protocol meets information needs for
populations and habitats .
- ranges and trends for many species
- effects of management actions
- larger context of management actions
24MSIM Protocol meets information needs for
populations and habitats .
- ranges and trends for many species
- effects of management actions
- larger context of management actions
- habitat associations
FIA point - Plant and animal species -
Detailed vegetation data
Landscape around point - Remotely-sensed data
(veg, soils, disturbance)
25Monitoring Data are Integrated
26In sum, MSIM will work at a large scale to
provide information on
- Species range and distribution
- Co-occurrence among species
- Occupancy of specific habitats
- Trends in occupancy over space and time
- Trends in habitat over space and time

48Multiple-Species Approach Dry Run
- What if
- We implemented 10 standardized, commonly employed
multiple species detection methods for
vertebrates - At each FIA grid point on NFS lands in the Sierra
Nevada, and - Based on estimates of the number of points in
each species range and their probability of
detection with the 10 protocols, then - Which species would we expect to observe at
enough points to detect gt 20 change between two
time periods with 80 confidence and power?
49MSIM Predicted Effectiveness
- Based on modeling, over 60 of all vertebrate
species, and 80 of all vertebrate MIS species in
the Sierra Nevada were predicted to be observed
frequently enough to detect. - 20 relative change in observations with
- 80 confidence and power
50MSIM Predicted Effectiveness
- Based on modeling, over 60 of all vertebrate
species, and over 80 of all vertebrate MIS
species in the Sierra Nevada were predicted to be
observed frequently enough to detect. - Most species considered potential indicator
species were also adequately detected
51MSIM Predicted Effectiveness
- Based on modeling, over 60 of all vertebrate
species, and over 80 of all vertebrate MIS
species in the Sierra Nevada were predicted to be
observed frequently enough to detect. - Most species considered potential indicator
species were also adequately detected - Species predicted to be adequately detected
represented a balance of life history
characteristics and habitat associations,
including species of concern
52Specific 2002 Pilot ResultsSpecies Detections
53General Field Test ResultsPredicted
Efficiencies Realized
- Diversity of species detected
- Over 50 of all species expected were detected
- Logistically feasible to implement
- Habitat data needs to be collected at all sample
sites, not just center point - Cost estimates refined
- QA/QC measures need to be developed
54Factors Affecting Optimal Designs
Effort per point
Number of points
Probability of detection
Proportion of points with observations
Proportion of points occupied
Remeasurement frequency
- Habitat relationships
- Cause-effect relationships
- Indicator species dev./eval.
- Trend detection
- - occupancy, richness, comp
- Spatially explicit trend detection
55Parameters of Interest
- Probability of detection
- Estimates of
- proportion of points occupied
- probability of observation
- habitat relationships and indicator species
- potential cause-effect relationships
- Statistical power to
- detect change
- detect spatially
- explicit change
56Estimating Probability of Detection and
Proportion of Points Occupied
- Based on presence/absence data binomial
distribution - Maximum likelihood estimation to derive
probability of detection and proportion of points
occupied estimates - Program PRESENCE on the Patuxent Wildlife
Research Center website used for protocols with
one sample unit per point - SAS program written by Jim Baldwin (USFS
statistician) used for protocols with multiple
sample units per point (e.g., bats)

Results
59Change Detection Validation
- We were able to estimate p and PPO for about half
the species we detected - We expect this percentage to improve
substantially with a larger number of monitoring
points - Pilot had 20 to 40 monitoring points NFS lands
in Sierra Nevada have 1800 FIA points
60Change Detection Validation cont.
- For the 80 species for which we could estimate
probability of detection. - 78 were estimated to be adequately detected based
on our best guess of p and PPO (dry run) - 75 are estimated to be adequately detected based
on empirical data
61Change Detection Validation cont.
- The 80 species with estimates of p and PPO were
not always detected at a high percentage of
points
