These are pictures of the continuing work on the bee habitat on North campus. My class is putting in a green roof to not only help prevent erosion of the wall but to provide flowers for the bees.
Green roofs consist of many layers. Here students are installing a layer of rock wool, a fairly new material that has been used in stormwater management in green roofs.
Above the rock wool a filter fabric was put in. Here students are installing substrate above the filter fabric.
The substrate must be distributed in a 2 inch layer across the roof.
Sedum (stonecrop) is the most common genus of plants placed on green roofs.
Sedum planted in it's new habitat.
