Ironically, certain efforts at habitat preservation may be detrimental to species such as the Florida scrub jay. The jay lives in scrubland unique to central Florida (Florida scrub), an arid ecosystem which is dominated by shrubs and small trees and is also known for frequent wildfires. In the last century, much effort has been put into fighting and extinguishing wildfires, believing that they were decimating the ecosystems. However, these fires are actually a vital part of the scrubland; without frequent fires to weed out the larger trees and keep the plant and tree numbers down, the scrub becomes dominated by large oak trees. This makes the area unsuitable for scrubland animals such as the Florida scrub jay. As a result, preservation of most managed areas of Florida scrub now includes controlled fires.
