present. Complete the vegetation section of DATA FORM 1. 

 PROCEED TO (2) . 



(2) Soils. In some cases, It Is not necessary to characterize 

 the soils. Examine the vegetation of DATA FORM 1. Hydrlc 

 soils can be assumed to be present when: 



(a) All dominant plant species have an Indicator status 

 of OBL. 



(b) All dominant plant species have an indicator status 

 of OBL and/or FACW (at least one dominant species 

 must be OBL) .* 



When either (a) or (b) applies, check the hydrlc soils 

 blank as positive and PROCEED TO (3). If neither (a) nor 

 (b) applies but the vegetation qualifies as hydrophytic, 

 dig a soil pit at the observation point using the proce- 

 dure described in Appendix D, Section 1. Examine the soil 

 immediately below the A-horlzon or 10-lnches (whichever is 

 shallower) and compare its characteristics (Appendix D, 

 Section 1) with the hydrlc soil indicators described in 

 PART III, paragraphs 4A and/or 45. Record findings on 

 DATA FORM 1. If a positive hydrlc soil indicator is pres- 

 ent, the soil at the observation point is a hydrlc soil. 

 If no positive hydric soil Indicator is found, the area at 

 the observation point does not have hydric soils and the 

 area at the observation point is not a wetland. Complete 

 the soils section of DATA FORM 1 for the observation 

 point. PROCEED TO (3) if hydrophytic vegetation (1) and 

 hydric soils (2) are present. Otherwise, PROCEED TO 

 STEP 20d. 



(3) Hydrology. Examine the observation point for indicators 

 of wetland hydrology (PART III, paragraph 49), and record 

 observations on DATA FORM 1. Consider the indicators in 

 the same sequence as presented in PART III, paragraph 49. 

 If a positive wetland hydrology indicator is present, the 

 area at the observation point has wetland hydrology. If 

 no positive wetland hydrologlc indicator is present, the 

 area at the observation point is not a wetland. Complete 

 the hydrology section of DATA FORM 1 for the observation 

 point. PROCEED TO STEP 20d. 



Wetland determination. Examine DATA FORM 1 for the observation 

 point. Determine whether wetland Indicators of all three 

 parameters are or would normally be present during a signifi- 

 cant portion of the growing season. If so, the area at the 

 observation point is a wetland. If no evidence can be found 

 that the area at the observation point normally has wetland 

 indicators for all three parameters, the area is a nonwetland. 

 PROCEED TO STEP 20e. 



* Soils must be characterized when any dominant species has an indicator 

 status of FAC.
