History
• Global Inventory – whole
Province south of the 56th
parallel.
• Started in 1966, finished in
1973.

Presentation Topics
• History
• Forest Management Inventory
16 April 12, 2013
Forest Management Inventory
• 1974 – The Forest
Management Inventory
was piloted in District
14.
• Need to build in a
continuous update
function.
17 April 12, 2013
Forest Management Inventory
• To collect timber volume and other
statistics
• To provide up-to-date forest inventory
maps
• To provide data needed for the AAC
calculation
• To do special studies on growth, cull,
and decay as needed
18 April 12, 2013
Forest Management Inventory
• 1996 – The forest
inventory design was
expanded to include
a wide range of non-
timber measurements
19 April 12, 2013
Forest Management Inventory
• 2013 – The 4th
“ten” year re-
inventory cycle
for the Island
has begun.
20 April 12, 2013
Presentation Topics
• History
• Forest Management Inventory
• Inventory Components
21 April 12, 2013
Inventory Components “What we do”
• Capture aerial images
• Interpret aerial images
• Collect field data
• Distribute data / information
22 April 12, 2013
Capture Aerial Images
• 1/10th of the Island
flown
• Work is done in
summer and early fall
• Contractors are used
• Images are the
building blocks of the
Inventory
“Where, when, how & why”
23 April 12, 2013
Interpret Aerial Images
Interpretation = Experienced Estimations
• Type areas flown the
previous summer
• Work is done during winter
• Softcopy system is used to
delineate species, age,
height, crown density,
site, and stand boundaries
• Impossible to actually visit
each stand
“Where, when, how & why”
24 April 12, 2013
Collect Field Data
• Permanent Sample
• Plots (PSPs)
• Temporary Sample
• Plots (TSPs)
• Spacing Trials
• Ground Truthing
“Types of surveys ”
25 April 12, 2013
Field Data - PSPs
• 1,100 across Island
and Labrador
• 250 to 300 per year
• 4 and 8 year cycle
• Field 6 two man crews
• Growth patterns
for G &Y, benchmark
the forest state
“Where, when, how & why”
26 April 12, 2013
Field Data - TSPs “Where, when, how & why”
• 10,000+ since FMI began
• Usually areas just
inventoried
• 30 to 60, after PSPs are
completed
• Field 6 two man crews
• New volume info and
to check the quality of
interpretation
27 April 12, 2013
Field Data – Spacing Trials
• 7 trials across the
Island
• 4 year cycle
• 6 treatment, 3
replications
• Growth patterns
associated with
different spacings
“Where, when, how & why”
28 April 12, 2013
Field Data – Ground Truthing “Where, when, how & why”
• In areas currently being
interpreted
• Fall and winter
• A crew travels to stand to
check species, age, density
and site
• Benchmark patterns on
photos with actual stand
conditions

• The Future
30 April 12, 2013
The Future “Where are we going in short term ?”
• Improve P.I. efficiency and quality
Digital Imagery & Softcopy
31 April 12, 2013
Softcopy
“What is it?”
VS
We are just beginning
32 April 12, 2013
Softcopy
“Why – What do we gain?”
• Saves time (hopefully)
• we update instead of re-create
Productive
3,074,000
28%
Non-forested
53%
5,966,000
Non-productive
19%
2,130,300
33 April 12, 2013
Softcopy “Why – What do we gain?”
• Streamlines line work and attribute
capture
• Enhances access to auxiliary data
34 April 12, 2013
The Future – “Where are we going in near term ?”
• Automated Photo Interpretation
Not to replace PI but to aid him
• Lidar ??
Does it have an operational use?
Is it cost effective?
35 April 12, 2013
Presentation Topics
• History
• Forest Management Inventory
• Inventory Components
• Future Directions
• Conclusion
36 April 12, 2013
Conclusion
• The need is timeless
• A lot of data/info is collected
• Technology (softcopy and Lidar )
has potential to aid us
37 April 12, 2013
Conclusion
• Must supply something we need
• Must be more cost effective / efficient
than traditional methods
Hope to gain some insight into how
Lidar may address these 2 conditions
Lidar – Operational Use
