Bonanza Creek LTER: Annual Active Layer Depths from 2002 to Present in the Survey Line Fire near Fairbanks, Alaska

General Information
Data Package:
Local Identifier:knb-lter-bnz.240.25
Title:Bonanza Creek LTER: Annual Active Layer Depths from 2002 to Present in the Survey Line Fire near Fairbanks, Alaska
Alternate Identifier:DOI PLACE HOLDER
Abstract:

In 2001 the Survey Line Fire burned an area of black spruce forest along the Tanana River adjacent to the Bonanza Creek Experimental Forest. In 2002 two research sites were established within the burn, one in a dry area and one in a wet area. When wildfire burns through a northern black spruce forest there is usually a subsequent increase in depth of thaw, due to the reduction in the depth of the organic layer. Thaw depth is being measured annually at tweny points within each of these sites.

Methods and protocols used in the collection of this data package
Description:

Experimental Design

Probe readings are taken at 20 locations adjacent to vegetation monitoring plots. The polts encompass a 30 m X 40 m area and are spaced 10m apart.

Methods

Thaw depth is measured in centimeters using a metal probe at each of 20 vegetation plots at SL1A and SL1B. The probe point is 1.5m from the vegetation stake in line with the vegetation stake and the diagonal corner of the 1X1m veg plot. Measurements are done in mid to late September as close as possible to maximum thaw depth.

Sampling Area and Study Extent
Sampling Description:

Sampling Frequency

Annually in the fall, as close to the date of maximum thaw as possible

Sampling Extent:
Sampling Site: 
Description:SL1A -- In the summer of 2001 the Survey line fire burned a section of the Tanana flats just south of BCEF. This site was set up to match the rest of the floodplain successional sites except that instead of flooding the disturbance is fire. Before this site was burned it was and open black spruce forest with a feathermoss dominated ground cover.. Site alternate names: SL1B, BCEFY2
