Service Description: <div style='text-align:Left;font-size:12pt'><div><div>BackgroundThis dataset was created to provide operators and decision makers with current old forest stand information for the northeast. Existing old forest datasets have either been retired or are out of date. The dataset is generated following a similar approach to the legacy RSEA Old Forest Dataset, using a newer and more comprehensive version of the VRI, to capture stands that have matured to the 140 age criteria, and address known gaps in the older datasets related to Tree Farm Licenses. The data was derived using RSEA methodology where old forest polygons were extracted from VRI with the following logic: BCLCS_LEVEL_2 = 'T' And PROJ_AGE_1 >= 140. This dataset has not been modified or adjusted for Crown Forest Land Base or any other forest land base criteria. As such, this data is purely for the identification of old forest stands, irrespective of forest productivity, land ownership, or forest fire burn severity, and is not suitable for estimating stand reserves such as Range of Natural Variability without further analysis. The 140 age criteria has been applied to deciduous and coniferous stands.
