The lead budget has been determined for a forested watershed ecosystem at the Hubbard Brook Experimental Forest in central New Hampshire. The Experimental Forest ranges in altitude from 229 to 1006 m and covers 3076 ha. It is typified by an unbroken canopy of second-growth northern hardwoods with patches of spruce-fir, particularly at higher elevations. Lead from the atmosphere is accumulating in the soil at a rate of 305 g ha/sup -1/yr/sup -1/. At the current input rate the doubling time of the lead concentration in the humus is approximately 50 years.
