Historical ecology seeks to understand the natural processes and habitat types that were found in an area at a specified period in time. It is particular interesting for cities because historical habitat types have largely been replaced by highly modified systems. It is important, however, because understanding these patterns at a time when similar climatic and geomorphological forces were at play can provide insights into ways to manage the current landscape that are consistent with the climate, promote native biodiversity, and work with rather than against natural forces.
