Due to the expanse this river has, it influences and covers multiple ecosystems. There are five main ones that hold the biggest impacts on the land. The list is from the Southmost ecosystem to Northmost ecosystem.
1. Coast:
The coast is the saltiest of the bunch, both in weather and in salt content. The sandy beaches form the path to the river mouth. Rocks and boulders are scattered across the course powder. To the East a single cliffside rises and holds a spectacular view for sunsets. Tropical trees, bushes, and flowering plants flourish here. Vines and crawling plants rise along the rocky surfaces, including the cliff. The plants bring a soothing aroma to the surrounding area.
2. Islands:
Similarly to the coast, they appear to have a soft beachline with some added rockiness. The further in you go in the more of a climb it becomes. It soon becomes apparent that there is a thin layer of dirt and sand over the massive boulders that have created the islands. Just enough for there to be vegetation. The structures of solid mineral and crystal form unique peaks and shapes within the island itself. There is limited variety in the plant life, but the plants that take root grow in copious amounts. This causes the islands to be virtually untouched by all but the most dedicated animal or sentient species.
3. Forest:
The outskirts of the forest frame around one of the tendrils of the river. This forest is teaming with life, both with flora and fauna. The outskirts of the forest aren't as full of trees as when you travel further in. Due to this scattering of trees, it is much easier to see the area around. Sunbeams through the leaves are commonplace and help the prey animals blend into their surroundings. The deep, earthy smell permeates through the plants and reaches out to mingle with the salty aroma.
4. Grasslands:
One of the most abundant biomes that mingles with the river is the grassland. The tall grasses and plants sway with North-moving winds. The soft, but solid, dirt hold steady to the roots of all that grows there. Although it's exceedingly rare, the occasional tree does end up taking root. Only the quickest and stealthiest animals survive out here. the extremely fertile soil grows just about anything that makes it past the seedling phase. There are very few paths that make it through the dense grasses.
5. Hills:
The rolling hills are a staple of the Northern lands. These low but beautiful structures bring a texture to the land that wasn't there previously. Like the grasslands, they are full of grasses and shorter plants along with the occasional tree. Although it holds more hiding places and vegetation than the previous biome. These hills are known to hold many rich gems and bones from the long dead. They were once used as burial mounds for heroes and warriors. These people caused the hills to flourish with life.
I like the breakdown of how the Ecosystem works for different parts. Nice touch! ---------------------------------------------------------------- Feel free to check out my Rivers/Waterways entry: Loch Mesner
