e . Sample other observation points along the first transect. 

 Continue along the first transect until a different community 

 type is encountered. Establish a representative observation 

 point within this community type and repeat STEP 20c - 20d. If 

 the areas at both observation points are either wetlands or 

 nonwetlands, continue along the transect and repeat STEP 20c - 

 20d for the next community type encountered. Repeat for all 

 other community types along the first transect. If the area at 

 one observation point is wetlands and the next observation 

 point is nonwetlands (or vice versa), PROCEED TO STEP 20f^. 



f. Determine wetland-nonwetland boundary. Proceed along the tran- 

 ~ sect from the wetland observation point toward the nonwetland 



observation point. Look for subtle changes in the plant com- 

 munity (e.g. the first appearance of upland species, disappear- 

 ance of apparent hydrology indicators, or slight changes in 

 topography). When such features are noted, establish an obser- 

 vation point and repeat the procedures described in STEP 20£ - 

 20d. NOTE: A new DATA FORM 1 must be completed for this 

 observation point, and all three parameters must be character- 

 ized bij field observation. If the area at this observation 

 point is a wetland, proceed along the transect toward the non- 

 wetland observation point until upland indicators are more ap- 

 parent. Repeat the procedures described in STEP 20£ - 20d. If 

 the area at this observation point is a nonwetland, move half- 

 way back along the transect toward the last documented wetland 

 observation point and repeat the procedure described in 

 STEP 20c - 20d. Continue this procedure until the wetland- 

 nonwetland boundary is found. It is not necessary to complete 

 a DATA FORM 1 for all intermediate points, but a DATA FORM 1 

 should be completed for the wetland-nonwetland boundary. Mark 

 the position of the wetland boundary on the base map, and con- 

 tinue along the first transect until all community types have 

 been sampled and all wetland boundaries located. CAUTION: In 

 areas where wetlands are interspersed among nonwetlands (or 

 vice versa), several boundary determinations will be required. 

 When all necessary wetland determinations have been completed 

 for the first transect, PROCEED TO STEP 21. 



« STEP 21 - Sample Other Transects. Repeat procedures described in 

 STEP 21 for all other transects. When completed, a wetland determi- 

 nation will have been made for one observation point in each community 

 type along each transect, and all wetland-nonwetland boundaries along 

 each transect will have been determined. PROCEED TO STEP 22. 

 « STEP 22 - Synthesize Data. Examine all completed copies of DATA 

 FORM 1, and mark each plant community type on the base map. Identify 

 each plant community type as either a wetland (W) or nonwetland (N) . 

 If all plant community types are identified as wetlands, the entire 

 area is wetlands. If all plant community types are identified as
