The State of Chesapeake Forests Forest Fragmentation analysis characterizes fragmentation of tree cover across the entire Chesapeake Bay watershed at a 1-meter resolution. This dataset includes 8 classes: Islets: Small, isolated groups of tree cover too small to contain transitional forest (i.e., <30 m across).
Connected Canopy: Small groups of tree cover 100m from perimeter of patch.
Canopy Gap: Non-treed area within transitional, interior, or core forest
Perforation: 15m Edge associated with a canopy gap. |

| description:
|
This analysis groups land use classes from the 2021-2022 Chesapeake Bay Land Use/Land Cover (LULC) Database 2024 Edition (Claggett et al. 2025) into fragmentation classes based on the framework used by the Morphological Spatial Pattern Analysis (MSPA) tool (Soille and Vogt 2022). Additional post-processing steps include addition and aggregation of fragmentation classes to make the fragmentation data more accessible to their intended audience. The methods of this analysis were developed in consultation with members of US Forest Service (USFS) and the Chesapeake Bay Program’s Forestry Workgroup (CBP FWG). Note that our use of the term “forest” here is only for the purposes of this particular analysis to characterize fragmentation across the landscape. For definitions and estimates of total forest area, refer to the State of Chesapeake Forests Storymap and the LULC data documentation (McDonald et al. 2025). For additional information about the forest fragmentation analysis, please refer to the forest fragmentation technical documentation. |
