Yukon Fire History Atlas
Field Descriptions

Contents

Table Index


The records in these tables represent all the recorded fires that occurred within the specified time and place. The fires have been digitally captured and are represented as either a point or polygon feature. It is primarily the larger fires that have been digitized as polygons and mapped for this fire history atlas.

FIELD NAME FIELD DESCRIPTION
Fire Fire identification (ID) number
Fires with associated linked maps are represented with bold text.
For fires from 1960 onward, the fire ID consists of the district code and fire number .
For fires before 1960, the fire ID consists of the fire number only.
Year Year of fire
Previously unrecorded fires with unknown years have been associated with decades.
The codes for these fires, as they appear in the Year field, are as follows:
9950 = 1950s
9960 = 1960s
9970 = 1970s
9980 = 1980s
9990 = 1990s
9900 = 2000s
Start Date Date of ignition
District District abbreviations:
BC = Beaver Creek
CA = Carmacks
DA = Dawson
HJ = Haines Junction
MA = Mayo
OC = Old Crow
RR = Ross River
TE = Teslin
WL = Watson Lake
XY = Whitehorse
Lat Decimal latitude of recorded point of ignition, or centroid of mapped polygon
Long Decimal longitude of recorded point of ignition, or centroid of mapped polygon
Cause Cause of fire:
L = lightning-caused fire
H = human-caused fire
Action Type of action taken:
IA = initial attack
SA = sustained action
DA = delayed action
None = no action
Zone Fire management zone:
AZ = action zone
OB = observation zone
Class Size classification of burned area:
A = 0.01 to 0.10 ha
B = 0.11 to 1.00 ha
C = 1.01 to 10.00 ha
D = 10.01 to 100.00 ha
E = 100.01 to 1000.00 ha
F = 1000.01 to 10 000.00 ha
G = 10 000.01 to 100 000.00 ha
H = > 100 000 ha
Area (ha) Area (in hectares) of fires within Yukon boundary
For cross-border fires, only those portions that were within the Yukon are included.
These calculations include all non-fuel areas (e.g., water) within the fire perimeter
Perimeter (km) Calculated perimeter (in kilometers) for mapped fires
Perimeter of fire polygons has been calculated with Arcview GIS software.
