CHAPTER 3 – ECOLOGICAL UNIT INVENTORIES
3.2 – ECOLOGICAL UNIT MAPPING
3.21 - Preparation
Preparation of aerial photographs and photo file.
1. Clean backside of field sheets of all previous markings. Apply mapping record
format with large rubber stamp. Fill in neat line acres.
2. Set up file folder for each field sheet and stereo pair. Label file with flight line and
photo number (only even-numbered photos are field sheets).
a. Set up overlays for photo (do not allow overlay to lay on photo emulsion
during storage in file).
o Traverse overlay with photo number and neat lines on overlay. For field
notes, coding location of field note cards and other pertinent mapping
information; i.e., wetland type, habitat type.
o Landtype Association (LTA) overlay with photo number and neat lines,
establish LTA boundaries in green after mapping.
o Quality review overlay with photo number and neat lines.
o Transect overlay with photo number and neat lines. For recording
location of transect, stem analysis, forest site location, ECS plot center,
potential review stops, stems, site index, transects.
o Wetland type overlay using wetland (draft) maps identify and delineate
wetland types. Verify in field, complete summary.
3.22 - Design
1. Gather and study existing information for the field sheet
1. Delineate tentative LTA boundaries. Put ECS plot center directly on field sheet
(see conventional symbol legend). Add backlog Forest Site Numbers. Record
previous soil management service and/or mapping observations and information.
2. Use all available information for pre-field mapping and selection of traverse.
 All available aerial photography.
 Topographic maps.
 All timber type maps.
 Soil management service notes and maps, sample compartment soil survey
notes and maps.
 Wetland type maps.
 Others.
3. File field sheet, stereo pair, R9-2500-6, management service maps, and notes,
sample compartment overlay and notes and other documentation in file folder. Do
not use paper clips or staples in folder. Make sure overlays are not in contact with
emulsion of photo.
4. Stereoscopic interpretation.

 Natural slopes
 Changes in topography
 Identify glacial landforms
 Vegetation density, size changes, habitat type
 Drainage patterns
 Moisture regimes
 Road systems
 Root-raked areas
 Frost-pockets
 Others
5. Delineate landscape features that represent potential mapping unit separations such as:
those units which are distinct; e.g., bog delineate with solid line, those which
are questionable use dashed line. (This assists or influences your traverse location.)
 Distinct slope breaks (% and length)
 Distinct topographic changes and patterns
 Distinct vegetative density, size changes, habitat types
 Distinct drainage patterns
 Distinct color tone patterns of overstory and understory
 Other
Note: This step is very important to the mapper. First, it forces one to become very
familiar with the land before the field work. Second, it improves the predictive
ability of the mapper. Remember, a mapper only sees a small sample of the entire
population even in the field. Third, it provides the selection of the most suitable
and efficient traverse through the photo.
6. Predetermine the traverse and potential observation points on overlay.
2 – Field Work
Adhere to the Safety Plan
A. Follow traverse and deviate when necessary to sample mapping units and determine
composition.
1. Identify mapping units on overlay with current mapping legend symbols.
2. Record a minimum of one field note card per traverse.
3. Record a field note card for each extensive (200 ac.) taxanomic unit not
on existing legend. (Inclusions)
4. Amend the pre-field mapping unit delineations when necessary based on
field observations.
5. Note habitat type on overlay for each observation made.
3 – Finalize Mapping
A. Inking - Under the stereoscope ink directly on the leaf-off photos (photo set A) according to
the following guides:
1. All lines of uniform width.

CHAPTER 3 – ECOLOGICAL UNIT INVENTORIES
2. All letters and numbers are to be of uniform size [> 3/32" <1/8"] and neatly printed. (See
Figure 1)
3. Mapping unit symbols are to be centered in unit delineations where possible and
horizontal. Use sufficient symbols in irregular shaped mapping units to avoid confusion,
but not too many to give a cluttered appearance.
4. 4. Mapping units too small to put a symbol in will have the symbol arrowed in at 45
degree angle ( ) and inside of neat lines, whenever possible. Arrowed symbol cannot
cross a complete mapping unit.
5. Vary type of lettering as follows:
a. ELTP symbols - vertical capitals and numbers.
b. Large water features (large lakes, double line rivers and lakes) slant capital
print.
c. Small water features - slant and lower case.
d. Cultural features - slant lower case.

3.28 Field Notes and Descriptions
Field Note Cards. (Exhibit 2 and 3) The objective of the use of field note cards is to document
Ecological Landtype Phase (ELTP) unit information. This information is used to write ELTP
descriptions and site unit descriptions.
a. Mapping Phase. Complete field note cards will be taken for all site units within each
ELTP during field traverses. A minimum of one complete field note card is required for each
traverse. The specific number of field note cards per ELTP will depend on the amount of the
Landtype Association (LTA) occupied by that ELTP and the complexity of its composition.
b. Transects. Field note cards will be completed for all transects. The field note card
will be used to complete transect summaries.
c. Filing and Storage. Field note card files will be maintained. Cards will be filed by
LTA and by ELTP units. Each ELTP will have field note cards separated by Major Site Units
and each Minor Site Unit. When field mapping is completed in each LTA, the field note card
file will be maintained in a permanent file in the Supervisor's Office.
d. Instructions for Completing the Field Note Cards (Reference Soil Survey Manual,
Chapter 3)

Transect Method of Determination of Total Site Composition of Ecological Landtype Phase
(ELTP).
Knowledge of the kind (consociation, association, undifferentiated, complexes, miscellaneous
land types) of ELTP units is important for proper classification and consistency in the mapping
portion of the inventory. Most important, for interpretations and application of this information
by the manager, the composition of the components within the ELTP units is determined. Soil
scientists commonly estimate the proportions of the different kinds of components present from
scattered observations made during the course of mapping. Since interpretations for the Ottawa
National Forest ECS-SRI will be made for ELTP units, this method is not acceptable by itself.
Transects will be done to provide and document this information.
a. Point-intercept transects are required for determining composition of most ELTP units.
Transects will be low priority on acid bogs, and poorly drained floodplains.
b. Minimum requirement for number of transects: For minor mapping units, three
transects; for major mapping units, five transects.
c. Transects will be distributed throughout the extent of the ELTP unit in each Landtype
Association (LTA). Transects will be at least two miles from one another. Avoid regressed
sites.
d. Spacings between sample points are equal-distance for each transect. Actual spacing
is variable between and depend on size and complexity of the ELTP unit. The entire ELTP unit
will be represented in the transect and will determine the number of sample points. There will be
a minimum of four to six points per transect on consociations, six to ten on associations,
complexes, and undifferentiated units.
e. All total-site components will be recorded at each sample point to include a Field Note
Card (R9-ONF-2550-1a or 1b) and Ecological Vegetative Plot (R9-ONF-2550-4).
f. ELTP units must be carefully selected for transects to maximize time and effort to
obtain information. Most important, an ELTP unit must be representative of all total-site
components. Secondly, given a choice between several representative ELTP units, those with
potential stem analysis site trees are preferred.
g. A small diagram will be drawn of the transect (cross-section) on first field note card.
h. Where possible, direction of the transect should be perpendicular to landform axis.
Code and locate each stop on transect photo overlay. Code ELTP No. , photo no. , stop no. .
i. Begin at boundary of ELTP unit and record observations at a predetermined interval
designed for unit.
j. Complete a Field Note Card and Ecological Vegetation Plot for each sampling point.
k. Record sampling interval distance on Field Transect Summary.
l. Complete Transect Field Summary (R9-ONF-2550-5) for each transect.
m. Send completed Transect Field Summaries and paper copy of photo overlays to Forest
Soil Scientist for ELTP unit summaries and documentation in the Forest Soil Handbook.

3. Ecological Vegetative Data Collection
Requirements:
a. All site characterization (soil pedon descriptions-landform analysis) will have a
complete ecological vegetative plot sampled.
b. All sample points along transects (e.g., for ELTP unitcomposition) will have a
complete ecological vegetative plot sampled.
Procedure:
A 14x21m rectangular macroplot is laid out with the soil pit positioned in the center of the plot.
The macroplot is composed of six 7x7m subplots. Originally, the plot is laid out with string and
survey pins. Once the relative size of the macroplot becomes familiar to the sampler, the string
and pins may be discarded. Throughout the sampling season, periodic checks for accuracy will
be made by laying out the macroplot again with the string and survey pins.
An occular estimate of foliar coverage will be made on all plant species found in the six subplots.
The estimate of coverage will be taken from the center of each subplot which is located by
pacing from the center of the macroplot.
Foliar coverage is defined as the total area covered by the vertical projection of the foliage of
each plant species on each subplot.
Foliar coverage percent for each species will be estimated and recorded within each subplot as
one of the six coverage classes:
Coverage Class
0-5%
6-25%
26-50%
51-75%
76-95%
96-100%
Code Number
1
2
3
4
5
6
Unknown species will be collected and positive identification will be made at the office.
Other data to be taken are stand age, structure, stand origin, and evident historical factors which
would affect the present stand structure. Habitat type will also be recorded if known. Basal area
per acre will be determined by tree species using a 10 factor prism. The species of each "in" tree
will be recorded with its corresponding dbh class.
Ottawa Forms
Use R9-ONF-2550-4 to code vegetative data for each macroplot.

analysis, and final habitat type determination.
4. Field Determination of Potential Timber Productivity. Knowledge of the potential of the
adaptable tree species for each Ecological Landtype Phase (ELTP) mapping unit is one of the
more important contributions from the ECS-SRI. Presently, only general site index and volume
estimates are avilable for largely unidentified, undefined site conditions on a mix of existing
stand conditions.
As part of the ECS-SRI, potential productivity is determined for ecological mapping units on
carefully selected trees using procedures which will minimize measurement and result errors.
The integration of potential productivity with the total-site concept of the ECS-SRI provides
meaningful predictive capabilities for economic comparisons and other management decision
criteria.
A.
ECS-SRI Requirements
1) A minimum of 9 trees per species per Site Unit per ELTP.
2) All northern hardwoods (sugar maple, red maple, yellow birch, paper birch, basswood,
elm, white ash, black ash, black cherry, northern red oak, and aspen) will be measured
by stem analysis. Estimated height and age (site index) will be used for red pine, jack
pine, white pine, black spruce, white cedar, white spruce, tamarack, and balsam firplantation only. However, some stem analysis will be done on the softwood species to

CHAPTER 3 – ECOLOGICAL UNIT INVENTORIES
check site index and to determine site growth characteristics, a minimum of one tree per
set of three to five species.
3) Three separate locations (ELTP's) are required.
4) All Site Unit components (soil-landform-vegetation-riparian) will be fully described
whenever potential productivity measurements are made.
5) Three trees of each species should be measured from each Site Unit.
6) Selection Criteria
1. Site Unit conditions required.
a) The soil taxonomic unit, habitat type, and landform position should be the
dominant or co-dominant Site Unit within the ELTP mapping unit being
sampled. Priority is on major Site Units.
b) Check site variability by traversing a 1/5 acre plot and making three soil
observations from shallow pit and auger holes. All observations of the soil
component must be within the range of characteristics of that soil taxonomic
unit as defined in the soil taxonomic description. When the site is selected, field
note card will be done.
c) Either all ecological vegetative plot microplots from transects must be of the
sample habitat type or the uniformity of the habitat type must be checked during
the site variability (item 2) traverse and recorded.
2. Stand Conditions
a) Trees are of good to high vigor with a well dispersed, fine branching, and good
form without forks or severe crooks.
b) Trees must show no evidence of past suppression and are dominant or codominant. Check with the increment borer.
c) Stands are even-aged (age range is less than 10 years) and preferably 40 to 70
years old.
d) Stands are relatively free of past disburbance of fire, grazing, harvest, and other
growth disturbances.
e) Trees should be at least a stand height away from the influence of residual trees.
Avoid trees growing on different microsites.
f) Basal area should be 100 feet or greater.
B. Stem Analysis Field Procedure
1. Record basal area per acre (R9-ONF-2550-6 , Stem Analysis Data, Exhibit 6) for sample
plot if not already available from Ecological Vegetation Plot (R9-ONF-2550-4, Exhibit
4). Basal area will be determined by tree species using a 10 factor prism. Record proper
location symbol on photo overlay.
2. Fell selected trees leaving a one-foot stump. (Use certified chainsaw operators.) Check
stump for severe early suppression. If it shows suppression, stop and select another tree.
3. Record total tree height and merchantable height (4" DIB softwoods, aspen, 6" DIB
hardwoods) to nearest foot on R9-ONF- 2550-6. Measure and record sawtimber height
(softwoods, aspen, 7.6 " DIB; hardwoods 9.6" DIB), to nearest foot.

7. For each disk, measure and record on R9-ONF-2550-6 the outside diameter; then peel
bark from each disk and measure the diameter inside bark in the field.
8. For each felled tree, begin at the top of the tree and measure and record on R9-ONF2550-6 the internodes marking the recent annual height growth as far back as possible.
9. Place each tree disk in a burlap bag and transport to the office.
10. Air dry the disks. Record the ring counts as soon as possible to avoid problems with
shrinkage and cracking.
C. Site Index Field Procedure
1. Record date, author, photo no., ELTP, transect, stop no., basal area, habitat type, soil
classification, and micro-landform position. Record location with proper symbol on
photo overlay.
2. Record species for each tree sampled.
3. Record DBH of each tree using a diameter tape.
4. Determine height using either a Relascope or Clinometer for each sample tree.
5. Determine and record age using an increment core at specified height above ground.


3 years for red pine to stump age (1.0 ft.)

2 years for jack pine to stump age (1.0 ft.)

12 years for black spruce DBH age.

(on lowland, very poorly drained soils only)

for white spruce and balsam fir, see site index curves.

for white pine, add 4 years to stump age (1.0 ft.)

