Title:Carbon Dynamics Along a Permafrost Gradient at Caribou-Poker Creeks Research Watershed (CPCRW) in Interior Alaska: Forest stand structure in a 75x75m spatial domain along a permafrost and vegetation gradient.
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This dataset includes forest stand structure. Project summary: Specific leaf area (SLA, leaf area per unit dry mass) is a key canopy structural characteristic, a measure of photosynthetic capacity, and an important input into many terrestrial process models. Although many studies have examined SLA variation, relatively few data exist from high latitude, climate-sensitive permafrost regions. We measured SLA and soil and topographic properties across a boreal forest permafrost transition, in which forest composition changed as permafrost deepened from 54 to >150 cm over 75 m hillslope transects in Caribou-Poker Creeks Research Watershed, Alaska. This is an exploratory study to begin understanding SLA variation and controls thereof in a non-contiguous permafrost system.

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

Experimental Design

Six replicate 75 m east-west transects, spaced across 75 m according to a cyclic sampling design (3/10 with a 4 m gridcell, Burrows et al., 2002).

Methods

FIELD: Tree basal area (total and spruce fraction) and the number of tree individuals were determined in summer 2014. Every 10m along each of the six transects, semi-circle plots with 5m radius were established. Tree individuals were counted by species. Total tree basal area was determined by summing basal areas across species at each transect location. Specifically, tree diameter at breast height (DBH) was converted to basal area using: basal area = DBH^2 * pi. Spruce-specific basal area was measured by summing only spruce basal area measurements.
