Seven permanent forest plots established in 1998 provide detailed vegetation structure and composition data for the Baltimore Ecosystem Study. Plots range from 900 to 1600 square meters and were subdivided into grids for sampling trees, saplings, shrubs, vines, and seedlings. This dataset was collected by the Baltimore Ecosystem Study (BES) as part of the NSF Long-Term Ecological Research Network.
Use Cases
- Analyze tree species composition and height across 10x10 meter grid areas to model forest canopy structure.
- Study sapling density and vine/shrub cover along subplot boundaries to assess understory competition and regeneration.
- Quantify percent cover of species and physical material in 0.5x1.0 meter quadrats for ground layer biodiversity analysis.
- Correlate seedling counts and browse damage metrics with plot location to investigate herbivory pressure in urban forests.
- Compare vegetation data from plots in Oregon Ridge, Hillsdale, and Leakin Parks to assess urban versus non-urban forest characteristics.
Strengths
- Data collection uses rigorous spatial methods with plot side length accuracy within 0.5 cm.
- Sampling covers all vegetation layers (trees, saplings, shrubs, vines, seedlings) for a complete community profile.
- Plots were selected with specific, documented criteria (e.g., 80% continuous canopy, consistent drainage) to ensure comparability.
Limitations
- Dataset contains only 7 plots from a single year (1998), limiting temporal and spatial statistical power.
- The Hillsdale plot is smaller (900 m2) than others (1600 m2), introducing methodological inconsistency for area-based metrics.
- Sample size is small, with data from only three forest patches in the Baltimore region.
