The natural features of the Baldwin Hills are the foundation for the unique vegetation and wildlife of the area. The geology of the Baldwin Hills explains the topography of the hills, as well as the oil deposits, rock, and soil that make up the hills and have influenced their development over time. The soil types in the Baldwin Hills, where water flows and collects, and climate forms the conditions for certain plants and animals to thrive, both native and exotic. It is these natural features, along with significant human intervention in water and land use, which have created the Baldwin Hills we see today.
