| Importance of ReA | increasingly implemented for the rapid characterization of the biodiversity of an area. |
| What is an REA ? | a terrestrial area or region is a flexible, accelerated, and targeted survey of vegetation types and species. REAs utilize a combination of remotely sensed imagery, overflights, field data collection, and spatial information visualization to generate use |
| REA is not an exhaustive inventory of the biological resources of an area; a biodiversity monitoring program; a rigorous statistical assessment of ecological relationships; an environ- mental impact assessment; a management plan; basic research to unders | False |
| the idea to conduct an REA emerges, and initial discussions about the merits and shortcomings of the approach are held. The need to generate biological information for an area can be identified by governments, local people, international scientists, in-co | Conceptual Development |
| During this phase, the primary implementor officially proposes to do an REA and usually attempts to identify the geographic extent, determine the objectives, secure financing, identify collaborators, develop time frames, and solicit input from the scienti | Initial Planning |
| phase entails the interpretation of imagery (satellite images or aerial photographs) to classify the landscape under study into a system of vegetation units, typically vegetation types or land use–land cover classes. | Initial landscape Characterization |
| The classification is preliminary, and the vegetation types need not be identified during the conceptual phase because they will necessarily be verified in subsequent fieldwork. It is, however, extremely important to assign all of the land area that const | false |
