Intensive green roofs with great media depth and plant selection offer ample opportunities for biodiversity. Ramps or tiered levels offer roof access to non-aerial fauna setting the stage for the introduction and interaction of the surrounding ecology. Just because a large animal such as a bear or moose may inhabit the local area does not mean that the intensive green roof must attract it to make the biodiversity effort a success. Creating an environment which supports a variety of plants and fauna on the lower levels of the food chain benefit the entire food web for the surrounding area.
