Farm: Ballyhornan, Down
Wild bird cover and the retention of winter stubbles were chosen to help provide adequate feeding opportunities for priority seed-eating bird species such as the yellowhammer, tree sparrow, skylark and linnet. These features are important during the harsh winter months, when food sources are often scarce.
Rough grass margins were also incorporated in a number of areas on the farm. This feature provides an excellent habitat for insects, which help to feed chicks during the summer.
The management options put in place fit in very well to my farming system. The majority of my crops are spring sown, meaning that the adoption of overwintered stubbles has little impact upon my farming operations. The rough grass margins have been introduced in areas, which traditionally produce lower crop yields. This means that any income losses have been minimal. My farm was part of the RSPB’s Yellowhammer Recovery Project (2006-2011), which attempted to reverse the critical declines in farmland seed-eating birds. In participating in this project, I received regular support and advice from an RSPB advisor on how to manage features for the benefit of wildlife.
Following the harvest, I retain 14 acres of winter stubbles from the barley crop until the spring. This provides a food source during the winter in the form of split grain.
I also sowed one hectare of wild bird cover in spring, usually around May, using a one-year mix. This crop is left un-harvested over winter, providing more seed sources for the birds.
Originally, I had sown the two-year mixed crop wild bird cover. However, a weed problem began to take hold. As a result the wild bird cover did not establish itself properly, whilst weed seeds started to establish themselves in my barley crop. I moved to the one year mixed wild bird cover, which achieved better results.
Wildlife has definitely benefited because of the options put in place. In the space of five years, surveys of my farm showed that yellowhammer numbers increased from 10 to 18 pairs. Additionally, numbers of house sparrows and linnets more than doubled in this time. This demonstrates that well managed arable options are effective in supporting seed-eating farmland birds.
The creation of rough grass margins on the edge of watercourses acts as a buffer preventing the spread of pesticides and fertilisers from the field into the water.
