A network of underground aquifers provide a constant source of water to seeps within Ash Meadows in the heart of the Mojave Desert. These spring-fed aquatic habitats stand in stark contrast to the dry, desert conditions surrounding them. How unique is the algal flora of these isolated spring-fed seeps? We aim to understand the algal diversity of the aquatic habitats with Ash Meadows and the results of our study will provide valuable information for the future management of this unique system.
