PWETL - Percentage of wetland The percentage of wetland cover is calculated by dividing the number
of wetland land cover cells in the 1 km grid cell reporting unit
by the total number cells in the grid cell boundary minus those
cells classified as water (total land area). Forests and wetlands
act as filters, removing pollutants from runoff before it enters
streams. Forests and wetlands also provide habitat for a wide variety
of valuable plant and wildlife species. |
