 | | Remote sensing should be among methods of choice for monitoring riparian zones, since these corridors stretch over thousands of kilometers, cross national borders and are difficult to survey on the ground (Nagler et al., 2001, in press). |
 | | Remote sensing methods for estimating plant cover have largely replaced manual methods of determining vegetation percent cover (including other factors such as plant type, height, and density), but this conversion of methods has primarily been for non-riparian biomes, such as grasslands, coniferous and deciduous forests, and agricultural settings. |
 | | Although remote sensing provides consistent, large-area coverage of riparian regions, which are difficult to access by land due to a lack of roads, Huete et al. |
