Habitat changes
Favorable quail habitats were well represented on family farms throughout the country in the 1930s through 50s. Sharecropping and the early century farming practices created a patchwork effect across the countryside that was beneficial to quail and other small game species. The annual disturbances of fields by farming, the frequent use of fire, the somewhat inefficient methods that left weeds and fencerows along the edges and waste grain in the fields created ideal habitat conditions, and quail flourished in those communities. During the Great Depression, many family farms were abandoned as families moved to town or sold their property. The farms left unattended quickly left the early successional stage and rapidly progressed to mid-to late successional plant communities. Many farms were also planted into trees or quickly developed into young forests, eliminating the most conducive stages for quail. Some family farms were combined with other farms to develop larger or, in some instances, corporate farms. In these cases, smaller fields were combined and their fencerow borders eliminated to make room for larger and more efficient equipment. The loss of the family farms and fencerows with their benefits was probably one of the most detrimental losses for quail.
The continued demise of the small subsistence farms and urban sprawl have contributed to a change in the overall landscape of the country. Besides the loss of patchwork farming, former farm fields began to be planted in fescue and pine trees, especially in the Southeast. Fescue, Bermuda grass and other introduced grasses are important grasses for grazing and erosion control, but provide almost no benefit for quail from a nesting, brood or cover standpoint. Fescue began replacing more wildlife-friendly mixtures present in the old farming scheme. Fescue has also been blamed for the decline in other grassland bird species. Korean or Kobe lespedeza was planted and used widely for hay production on historic family farms. Many "old timers" just referred to the fields as "lespedeza", which is a valuable source of food and nesting cover.
Habitat changes are sometimes subtle. Many landowners claim that their farms have not changed in 20 years; however, from the quail perspective, they have had dramatic changes. For instance, some owners claim that a fencerow between fields is still there. Even though the overall location may be the same, if no cutbacks have been made to the fencerow, there have been dramatic changes. What used to be a low growing, relatively narrow strip with weedy edges and an overhead canopy has now turned into a wide sprawling tree row with no ground cover and very little wildlife benefit. Other vegetative and ecological changes take place and sometimes go unnoticed.
Despite a growing awareness of the importance of preserving and improving upland game habitat, more and more quail habitat is lost each year. In addition, severe seasonal weather conditions such as drought and extreme cold can decimate upland bird populations, especially in the fringe of their ranges. Most agencies are still encouraging individual landowners, but more importantly, have also begun to implement wide-ranging "landscape" approaches. The formation of the Southeast Quail Study Group and the Northern Bobwhite Conservation Initiative are recent examples of a multitude of partners working together to address quail populations on a regional and national scale.
