Web22 de mai. de 2006 · Retrospective modeling using five decades (1957–2004) of Hubbard Brook daily mean temperature data suggests significant trends (P≤0.05) towards an earlier spring (e.g. sugar maple, rate of change=0.18 days earlier/yr), consistent with other studies documenting measurable climate change effects on the onset of spring in both North … Web• Because these forest types are so widespread, overall impacts from climate change are likely to be highly variable, and often limited by specific site conditions (soil, existing species composition, etc.). In general, northern hardwood species are more likely to shift north or up slope, and be replaced by hemlock-hardwood-pine species.
