The additional plants we would need are some more ferns to go around the base of the redwoods. We might also want to add some other flowers found under redwoods for aesthetic affect. Another problem is the ground and soil. It is absolutely awful and the only way to fix it is by machine. Next year maybe the class that take up this job could arrange something to replace the rock hard dirt. Once we have well planted plants and good soil, we should put designated pathways in the biomes so that people do not walk on our plants. I do not think fencing is necessary and it would ruin the look. Lastly, I think a good watering system is necessary and we could arrange one of the systems with small tubes that water all the biomes. Even more advanced we could water each biome with the amount of water that it needs specific to its type of plants. The biomes could be used as a teaching tool as well as a good looking part of San Marin. Students from San Marin and middle and elementary schools could use the biome to study insects, abiotic, biotic, and many more factors.
