In areas where Lombardy (populusnigra Italica Muench) grows in Pakistan crown biomasss is lopped at various intensities and the woody branches and foliage components are used as fuel wood and fodder. The objective of this study was to developed simple and practical prediction models using linear regression to estimate crown biomass. Models were developed for green and air-dried branch wood and fodder crown biomass components under different lopping intensities. Tables were produced to formulate management, planning and marketing strategies. Diameter at breast height squared (Dbh2) and its square proved to be the independent variables to predict crown biomass weights.
