How used

1. Vegetation w/ obscure boundaries & high interspersion?

na

--

requires field inspection

2. High vegetation/open water interspersion?

Wetlands.shp

Class1_c

look for open water (UB) interspersion with vegetation

3. 3 vegetation classes or 2 classes + open water present?

Wetlands.shp

Class1_c

if number of unique Class1_c codes > 2, then answer "Y"

4. Wetland >50% Type 6 or 7?

Wetlands.shp

Class1_c

if FO or SS area is >50% of total wetland area, then answer "Y"

5. Wetland >50% coniferous forest?

Wetlands.shp

Class1_c, Sclass1_c

if Class1_c = FO and Sclass1_c = 2 or 4 for >50% of wetland, answer "Y"

6. Herbaceous, trees, or shrubs 10-50% of inundated wetland?

Wetlands.shp

Class1_c

if Class1_c is EM, SS, or FO within >10% of inundated wetland, answer "Y"

7. Herbaceous, trees, or shrubs <50% of inundated wetland?

Wetlands.shp

Class1_c

if Class1_c is EM, SS, or FO within >50% of inundated wetland, answer "Y"

8. Snag trees?

Wetlands.shp

Class1_c, Sclass1_c

field inspection is best; if Class1_c = FO and Sclass1_c = 5, answer "Y"

9. Mudflat present?

Wetlands.shp

Class1_c

if Class1_c = FL, answer "Y"

10. Lacking ditches, channels, levees etc?

DRG

--

look for ditch or channel

11. 0-20% impacted by excavating, filling, farming, tilling, etc?

Wetlands.shp

Smod1_c

if Smod1_c is x or s within 0-20% of wetland, then answer "Y"

12. Watershed 0-50% impervious?

Forests.shp

Csa_symbol

impervious classes are road (Rd), rock outcrop (RO), and development (Idev)

13. Watershed >50% forested or scrub shrub?

Forests.shp

Csa_code

non-woody classes are 83, 84, 87-98

14. Low potential for waterborne contaminants from landfills, etc?

na

--

requires field inspection

15. Wetland >1,000 ft from usual places of human activity?

Forests.shp

Csa_code

if Csa_code = 92, then answer "Y"
