Various papers published on the theme related to gum and resin bearing species in different journals and proceedings were collected and strictly assessed to fetch relevant information. The aim of this paper was reviewing the growing knowledge on the status, constraints associated toresource development and conservation and the collection techniques of gum and resins in woodland forests and their importance to support the livelihood and national income in Ethiopia. Gum and resins are important resources for securing a rural livelihood and marketed for earning cash income in the international market and create considerable job opportunities for communities. However, the population of gum and resin bearing trees are under high pressure due to continuous tapping, fire, intensive tapping, overgrazing, shifting cultivation and inappropriate land use system. But, they can be propagated by vegetative or by seed. Gum and resins are collected by tapping and natural oozing. Tapping enhances yield and quality of gum and resins. Inaccessibility of the area where the gum producing species grow, deforestation, overgrazing, improper tapping, resettlement, harvesting for fuel wood and land use change are constraints for conservation and development of the habitat of gum and resin species.
