The birds and the bees: Identification of bird and invertebrate fauna providing ecosystem services following restoration plantings at the Lincoln University Dairy Farm

Abstract

This study monitored the birds and invertebrates in the native corner plantings, native corridors, and the pasture at Lincoln University Demonstration Dairy and compared their diversity and abundance in three habitat types. A baseline study was previously completed in 2008/2009 and had assessed the presence of birds in the pasture just after the native planting. In late November and early December 2016 five-minute bird counts were completed in 20 pasture sites and the four native corner plantings. A range of entomological monitoring techniques were used in each site including pan traps, pitfall traps, wooden discs, and leaf litter extraction. A total of 22 bird species were found, 11 native and 11 exotic species. There were three more bird species observed in 2016 compared to the 2008 study. A total of 74 invertebrate species were found. Native plantings had the highest abundance and richness of invertebrates followed by the corridors, then the pasture. A range of ecosystem services are provided by the birds and invertebrates that include predation and pollination. The plantings also provide shelter for stock, greater on-farm native plant diversity and enhance aesthetic appeal.
