Abstract: Eleven eucalyptus species are characterized for morphological, chemical, pulp and paper-making characteristics to get high pulp yield of good strength through social forestry in north Indian topological conditions. Eucalyptus grandis of Bhadrachalam and Saharanpur origins give very good fibre dimensions, especially slenderness ratio, which is directly comparable to Pinus kesiya. Other eucalyptus species have shorter fibres and narrow lumen with thick wall resulting to poorer flexibility, higher Runkel ratio and rigidity coefficient. The chemical analysis of eucalyptus species reveal satisfactory levels of holocellulose (except Eucalyptus camaldulensis) and Klason lignin content (<30%) (except Eucalyptus camaldulensis and E.-348 hybrid). Relatively increased (>25%) lignin content except E.-413 (hybrid) might require additional pulping time and chemical charge compared to other species. Kappa number (<22), pulp yield (>48%) and higher strength properties of E. grandis of Bhadrachalam and Saharanpur origins, Eucalyptus torrelliana, Eucalyptus camaldulensis and Eucalyptus alba showed their suitability for social forestry.
