Delaware Tidal Wetland Condition Assessments Since 2008

Field data collected since 2008 assesses the condition of Delaware's tidal wetlands using the Mid-Atlantic Tidal Wetland Rapid Assessment Method (MidTRAM). The dataset includes metrics for hydro attributes, habitat structure, species richness, and surrounding land use impacts. It is provided by data.delaware.gov, with the latest update in October 2022.

Use Cases

• Model wetland Condition category from Hydro attribute score, H2: Fill rating, and B3: % surrounding development.
• Analyze the relationship between HAB4: Species richness count and invasive species pressure via HAB4/6: % invasive co-dominant species.
• Assess landward migration barriers using B5/6: Barriers to landward migration % perimeter obstructed alongside B2: Avg. buffer width.
• Predict H4: Docks/duck blinds rating based on B1: Estimated % with 5m-buffer and Depth of organic layer (cm).
• Correlate habitat structural integrity from HAB1: Structural patch type # patches with HAB2: Horizontal veg obs rating.

Strengths

• Data collection spans over 14 years since 2008, providing a long-term view.
• Includes over 30 specific assessment columns covering hydrology, habitat, and buffer conditions.

Limitations

• Sample size and row count are unknown, limiting statistical power assessment.
• Data may have geographic bias, focusing only on Delaware tidal wetlands.
• Contains placeholder columns like 'Other13', indicating potential data organization issues.
