Definitions:
- Forest Patches (Wooded or forested with non-turf understory): Woods grazed but not burned, some forest litter (Fair Hydrologic Condition).
- Grass/Scattered Trees (Lawns, parks, golf courses, cemeteries, etc.): Grass cover < 50% (Poor Hydrologic Condition).
- Disturbed land - Graded, grubbed, minimal vegetation.
- Impervious Surfaces: Buildings, pavilions and other man-made structures, paved streets, open ditches.
- Sequestration: The rate at which a tree adds carbon to its biomass.
- Carbon storage: The amount of carbon stored in tree biomass.
