Looking for Pioneer Species
Hey everyone, I'm an AP Environmental Science student looking to return some unutilized, urban land in Los Angeles back to it's pre-developed state. I am challenged in LA because years of trampling and urbanization have left soil layers disturbed, compacted, and contaminated with heavy metal pollution.
I'm exploring soil remediation methods right now, but I also need to know some native pioneer species which can be implemented at the site to replenish organic matter in the soil. As a result of the soil problems described above, in many cases the humus layer of our local soils has been almost entirely washed away due to soil erosion.
To clarify, I'm looking for grasses and annual plants that will die and compose naturally, making way for more specific species to be planted. (ex. Pseudognaphalium californicum)
