Description
Above-ground total tree biomass in an old Sequoia sempervirens stand at Bull Creek was extremely high, exceeding 300,000 g/m². Productivity was studied via tree re-measurement in 1972 and 2001, with above-ground net primary production (ANPP) estimates ranging from 600 to 1,400 g/m²/yr. The dataset contains site characteristics, stand descriptors, and calculated biomass, ANPP, and woody detritus input data.
Use Cases
Calibrating allometric models for tree volume and biomass based on tree circumference measurements.
Analyzing long-term changes in forest stand structure using re-measurement data from 1972 and 2001.
Estimating carbon sequestration potential in coastal redwood ecosystems using ANPP and biomass values.
Studying the impact of tree mortality on net primary production over a multi-decadal period.
Strengths
Provides a 29-year longitudinal study of tree growth and mortality (1972-2001).
Includes specific quantitative estimates for key ecological metrics, such as ANPP (700-1000 g/m²/yr) and biomass (>300,000 g/m²).
Data files have been checked for accuracy and are identical to the original 2005 publication.
Limitations
Column names and the exact number of rows are not specified in the provided metadata.
There is a conflict in the 'last updated' date between platforms (2001 vs. 2026), suggesting metadata may be inconsistent.
The dataset is limited to a single, specific old-growth stand, which may limit generalizability.
