This is a continuing study, initiated in 2003, to determine growth, survivorship, and phenological responses of temperate trees to soil warming. From 2003 through 2010, we determined that shade-tolerant, normally slow-growing species benefitted most from warming. We are continuing to study species-species responses to investigate the duration of and mechanisms behind species and functional group responses to soil warming.
As of spring 2023, the warming system ceased functioning. Thus, we are continuing our demographic research and also doing maximum photosynthetic rates (Amax) and mid-season green leaf tissue chemistry to document potential post-warming legacy effects to compare with responses found when soil warming was on. In 2023 we will harvest select juvenile trees to assess changes in biomass allometric responses induced by soil warming.
