Hello, My name is Sandra Bernal, I'm from St. Mark Catholic School. My question is, What kind of data have you already collected? Thank you for your time.

production, soil pH, air and soil temperatures, amount of greenness,
plant growth events, plot species composition, plant and ecosystem
respiration measurements, microbial biomass, and soil water chemistry
are among many bits of data that have been collected. There are plot
photos documenting the looks of the plots, soil and root enzyme
analysis, and data on amounts of N in the soil. All of this information
together helps answer questions about the role N plays in the system and
how the ecosystem will be affected by earlier snowmelt and/or warming
temperatures. Great question! I have helped collect some of this data,
but the real experts are the principal investigators, grad students, and
research assistants on this project.
