Farm: Grange Farm, Cambridgeshire
We include two skylark plots per hectare in all winter cereal fields on the farm as an easy means of supporting skylark numbers on the farm.
In 2009, we trialled spraying out the plots, and found that they worked successfully for skylarks provided that they were sprayed before the end of December. From 2013 this will be the preferred way of creating them, as our contractor has changed to an 18m drill and is less able to create plots when drilling. It also means that the plots are exactly 4m x 4m and so we are taking less land out of production. The plots are sprayed out using a 36m boom sprayer which is pre-programmed to spray out the plots at specified locations within the fields.
The plots work extremely well for us, increasing skylark territories from 10 in 2000 to 43 in 2012. We have good crop yields (9 t/ha for winter wheat and 3.2/ha for oilseed rape), having been doing skylark plots for 12 years now.
Skylark numbers have increased by over 400% on the farm in the last 13 years, against a backdrop of continued decline in the East of England as a whole. Monitoring nesting success in the first three years of using skylark plots showed that the number of nesting pairs in fields with plots increased and the number of chicks that each pair rears also increased.
