Attribute #2: Aquatic Ve~etation Density and Distribution Values for this attribute should be determined from the period of peak vegetation biomass, generally the end of July or early August. Select the DENSITY V ALOE using the DENSITY description or aquatic vegetation biomass figure which best describes the situation at your lake or pond. Then select the DISTRIBUTION VALUE using the DISTRIBUTION description. Finally, the DENSITY and DISTRIBUTION V ALUES are used to determine the VEGETATION V ALOE found below. DENSITY VALUE DENSITY VALUES: DENSITY Description: Vegetation Lb. per Square Yard Vegetation Kg. per Square Meter --- ---- --- ===~-- ====== ---- ------- HI Dense mats. usually emergent. Impossible to retrieve a lure without snagging vegetation. >3.0 >1.5 MED Intermediate density between HI and LO. 1.0-3.0 0.5-1.5 LOW Sparsely distributed as a whole, but may be small patches of dense growth. Can retrieve a lure weed-free most of the time. <1.0 <0.5 DISTRIBUTION VALUE DISTRIBUTION VALUES: DISTRIBUTION Description: -======== --=--=---= HI MED Vegetation is present across >50% of lake bottom. Vegetation is present across 30 - 50% of lake bottom. LOW Vegetation Is present across <30% of lake bottom. VEGETATION VALUE Use the DENSITY VALUE and DISTRIBUTION VALUE from above to determine the VEGETATION VALUE in the table below. VALUES LOW MED HI LOW LOW LOW MLO MED LOW MLO MHI HI LOW MHI HI DENSITY VALUES VEGETATION VALUES ---------- ---------- DISTRIBUTION LOW MLO MHI HI Record the VEGETATION VALUE (LOW, MLO,MHI, or HI) on the I Worksheet 37
