Jack Pine Biomass and Climate Data for Mississagi, Canada

Ontario's Mississagi River area hosts this dataset of jack pine ecosystem studies from 1969-1973. It includes two text files: one with field data on stand characteristics, biomass, and nutrient content from three plots of different ages, and another with precipitation and temperature records from nearby weather stations. Net primary productivity estimates are derived from above-ground tree growth and litterfall measurements.

Use Cases

• Estimating net primary productivity (NPP) for jack pine stands using columns for above-ground tree growth and litterfall production.
• Analyzing the relationship between stand age and biomass accumulation via stand characteristics and age data.
• Correlating local forest productivity with climate variables using the paired precipitation and temperature records.
• Studying nutrient cycling in boreal forests through data on nutrient content in vegetation, litterfall, and soil horizons.

Strengths

• Data is revised for accuracy, with specific corrections noted for temporal coverage and litterfall values.
• Provides detailed, age-specific productivity estimates (e.g., 289 g/m2/yr for 20-30 year stands) and litterfall measurements (e.g., 372.9 g/m2/yr).
• Includes complementary climate data from two distinct weather stations, enhancing ecological analysis context.
• Field data collection spans a multi-year period (1969-1973) across three distinct forest stand ages (20, 30, 65 years).

Limitations

• Key structural metadata (row count, column names, file size) is unavailable from all sources.
• NPP values are estimates derived from growth and litterfall, not direct measurements.
• There is a conflict in the 'last updated' date between sources (1990-12-31 vs. 2026-03-12).
