The theoretical basis my research is based on is all the theories that relate to soil pH influences on environmental conditions. The acidity or basicity of a soil affects the presence of nutrients, the toxicity of heavy metals and the microbial community living in the soil. All three of those can affect the health and growth of plants, and the capability of plants to live at the different levels of these creates niches. With this in mind its easy to see how soil pH could be the factor causing different species to live in the two patches of ground I was investigating.
