While other types of wetlands are very nutrient-rich, bogs are clearly defined by their lack of nutrients and their relative inability to support large plant life. A bog is created over hundreds or thousands of years, formed when plant matter decays in a lake and fills it. This creates layers and layers of peat, which is often drained before being harvested and burned as a heat source or used as insulation. Bogs are freshwater, and in spite of the large amounts of decaying plant matter, they are very poor in nutrients because of the slow rate of decay. Most of the plant life around a bog is along the lines of fungi, mosses, and small shrubs. Many carnivorous plants, such as the pitcher plant and the sundew, have evolved in bogs to combat the low nutrient levels in the soil. Bogs are infinitely valuable in their ability to store carbon, removing this greenhouse gas from the atmosphere.
Just looking up some stuff about bogs . . . that stuff is brutal. The decay is slow and the elves can feel it. Their lake is slowly decomposing the remains of their life tree. They can't grow what they used to.
Also, the bog has to be a separate entity, either within the Swamp or next to it. I like the idea of it once being its own land until a great continental shattering happened (perhaps the entry of Don Joswee) (Can Don Josee be the Death god from earth unlocked by Cid's planar meddling?). This led to a once vibrant forest being subjected to tidal estuaries in a dramatic fashion. The tree died, their culture died, and soon their home died and became a swamp. Some exiled themselves to the Underdark Forest, some made a boat from the remains of their world tree and said that it would find fertile ground. These would later be the blood elves of Isla Mogila.
