If it succeeds, the Metatron will allow tests of corridors that are difficult to impossible in nature. For example, although corridors are created or restored to increase population persistence, there are no good tests in nature that they do this. Further, for ethical reasons, it is difficult to test the effects of corridors on invasive species, and experimental work on invasives is possible in the Metatron. Inevitably, there are tradeoffs between tests of corridors in experimental (controlled, less realistic) and observational (realistic, less controlled) studies. Both are needed to successful test and understand the role of corridors.
