Tanana River Valley Fire Chronosequence - SFTS

Relationships
Data Holder: 
O'Neill, Kathy
Background
Year SFTS Began: 
1996
Continent: 
North America
Experimental Design
Design (short description): 
Chronosequence of burn scars 1, 3, 7, 10, 41, 80, and 140 years since time of fire (using 1997 as a base year). Control (unburned) stands for 1, 3, 7, 10, and 41 y.o. stands. All located in black spruce on permafrost. Mature black spruce stands are characterized by highly developed organic profiles that overlie the mineral soils. Sites underlain by permafrost.
Number of permanent plots: 
10-20
Environment

<400
Mean Annual Soil Temperature (C): 
Cryic/Frigid: <8C
Is temperature regime isothermic? ie, do mean monthly temperatures deviate by <6C?: 
No
Is atmospheric deposition chemistry monitored?: 
No
Dominant plant species (latin genus and species): 
Picea mariana
Landuse: 
Forestry
Ecoregion: 
Cool Temperate Boreal
Slope (%): 
0-2%
Geological material: 
Level to moderately sloping, well-drained silt loams over gravel or sand located on outwash plains or terraces of the Tanana River.
