Everything that’s done on the land affects wildlife,
either positively or negatively. That’s true for cropland, where habitat
quality is usually considered secondary to profitable cropping systems.
Profitable cropping systems can support wildlife, and
produce cleaner water and more productive soil, too. Consider making a conservation
plan that includes wildlife habitat in each decision
being made.
Follow four key thoughts:
Control soil
erosion. While soil conservation is basic to all farming systems, if you
think about it, covering the soil is as basic for wildlife habitat as it is to
soil protection. To have habitat, wildlife must have food and cover, and that’s
what basic soil conservation practices offer.
Grassed waterways, grassed field borders, grass or
riparian filter strips, terraces, crop rotations, field and farmstead
windbreaks-- all these basic practices offer cover and some food to wildlife.
In offering soil protection, they also contribute to
better water quality.
Use conservation
tillage. Leaving plant residues on the
soil surface after harvest, and through
the next year’s crop season as well,
protects the soil and offers cover
in the winter for many birds and
small mammals.
No-till farming, where the soil is disturbed little for
planting or through the crop season, helps nesting birds. An Iowa study shows 9
times the amount of bird nests in a no-till field compared to plowed fields.
Narrow row soybeans are likewise helpful to quail because there is no
disturbance during nesting season.
Time operations
for wildlife. Delaying any mowing of waterways, field borders, roadsides,
or hayfields until after nesting season is paramount to grassland bird
survival. There are also small but important operations changes that can be
made, such as mowing a field from the center to the edge, to allow wildlife to
escape from the mower into adjoining fields. And you can add a flush bar to
your mower to
get birds out of the way of the blade.
Maximize odd areas.
Make full use of non-farmed areas alongside crop fields by establishing habitat
used by the wildlife you want to see on your farm.
