Description
Long-term biomass and climate measurements from a semi-desert steppe at the Dzhanybek Research Station in Kazakhstan. The dataset includes a time series of peak live biomass from 1955 to 1989 (excluding 1976), seasonal above-ground biomass and dead matter from 1985-1989, and monthly/annual climate data from 1953-1989. Averaged values include above-ground live phytomass at 137 g/m², standing dead at 32 g/m², below-ground phytomass at 1,750 g/m², and ANPP estimated at 201 g/m²/yr.
Use Cases
Analyzing long-term trends in grassland biomass based on a 34-year measurement series.
Modeling relationships between climate variables and primary production using the provided monthly and annual climate data.
Calibrating or validating ecosystem models for semi-desert steppes using the detailed phytomass and ANPP estimates.
Studying seasonal biomass dynamics and dead matter accumulation using the detailed 1985-1989 seasonal measurements.
Strengths
Provides a long-term ecological record spanning 34 years (1955-1989) for biomass and 36 years (1953-1989) for climate.
Includes detailed, site-specific average biomass estimates (e.g., below-ground phytomass: 1,750 g/m²).
Data files have been checked for accuracy and are identical to the original 1997 publication.
Limitations
Row and column counts are unknown, limiting assessment of dataset granularity and structure.
Conflicting last updated dates exist between platforms (1989 vs. 2026), suggesting metadata inconsistencies.
The dataset excludes biomass measurements for the year 1976.
