Final answer:
Advances in ecosystem ecology, landscape ecology, and remote sensing have enabled ecology at a landscape level by providing new tools and approaches for land use and conservation planning. Computer modeling and geographic information systems have played a crucial role in this advancement, allowing for accurate assessments of ecosystem status and the collection of large-scale spatial data.
Step-by-step explanation:
Ecology at a landscape level has been made possible by new tools such as advances in ecosystem ecology, landscape ecology, and remote sensing. These tools provide sophisticated concepts and approaches for land use and conservation planning on a larger scale. For example, computer modeling and geographic information systems (GIS) have played an important role in the growth of conservation biology, allowing for accurate assessments of ecosystem status and the collection of large-scale spatial data. These tools have revolutionized and expanded the field of ecology, making it possible to study and understand the complex interactions between human and ecological processes in modified landscapes.
