Calhoun Line Notes
Vegetation Analysis
Vegetation Analysis Dataset Summary:
Vegetation data was collected along each trapline. Dates and formats of vegetation
analysis vary from line to line. In general, the line intercept method was employed in
1958, 1961, 1970, 1972 and 1975 on specific veg-lines.
Record Quality:
This database was created from photocopies of original records. In some cases data was
unreadable or illegible. Please accept our apology for misspelling of scientific names.
Also, it cannot be guaranteed that this is a complete record of all Calhoun line Data at
Sagehen Creek Field Station. Years, forms, and other info may be missing from this
Database. Please contact Station Manager in attempt to track down previous researchers
and Data originals.

Vegetation Analysis 1975:
'Do: -Take photos of each line (Black & White, Color slides)
-Lines: A= brush, spray, East
B= brush, spray, West
C= '68 burn, East
D= 68' burn, West
Others = Not necessary
-Sections: 5 sections on each line.
A= 3-4, 6-7, 10-11, 13-14, 18-19
B= 3-4, 9-10, 10-11, 12-13, 19-20
C= 3-4, 4-5, 5-6, 13-14, 19-20 (if one of these sections has been destroyed, select
another and indicate the #)
D= 1-2, 2-3, 4-5, 9-10, 17-18 ( if one of these sections has been destroyed, select
another and indicate the #).
-Record and label each section seperately.'
'Procedures: Standard line transect procedures. Stretch foot-inch tape along a section and record
in ' and '' the vegetation or substrate appearing under the tape. Record something for 100% of the
section length. If tree or shrub and/or herbs are growing together, pro-rate each. If more than one
item and cannot pro-rate, record the dominant item (e.g. young P. jeffrey with bare soil
underneath, record intercept of the tree).'
'Condition: Record the condition of shrubs and trees in addition to intercept.
A= alive
D= dead
R= re-sprout
S= seedling
(A,D,R, are especially important for sprayed area. Record % of each if part of 2 categories. e.g.
A 20%, D 80%, or D 30%, R 70%).'
'Woody species: Ceanothus velutinus, Ceanothus prostratus, Prunus symphornompos,
Arctostaphylos, Pinus murray, Pinus Jeffreyi, Rabbit Brush (Happlopappus chupothamnor),
Ribes, Chinquapin, Abies (w or r).
Herbs: Gayophytum, grasses, sedge, Phacelia, Wintergreen.
Substrate: Bare Soil (ind. stones <12''), Rock (12'' and larger), Litter (ind. stems <6''), Dead
Wood (stems 6'' and larger), Stumps or Tree.'
