You can also protect or restore water bodies, soils, and other ecosystems to meet the credit requirements. Doing so may require the help of a biologist or ecologist, whereas protecting or restoring vegetation may only require a landscape architect. ”Other ecosystems” is a fairly open-ended term, and a project that tries to protect or restore something outside of the defined list will be approved or denied based on your ability to justify it to the LEED reviewer on a project-by-project basis.
