The increasing migrating goose populations seasonally feed in the agricultural fields and grasslands. Annually, farmers encounter and abide the challenges of intense winter wheat and permanent grasslands grazing pressures. In Lithuania, migrating geese caused damages initiate conflicts between farmers, conservationists and hunters. Thus, we aimed to determine the winter wheat and permanent grasslands yield reduction by observing migrating geese grazing intensity and characteristics. In three Lithuanian south-western and central regions we established 15 study areas. During the spring migration geese droppings were counted every 10-15 days. Harvested winter wheat and hay were dried and weighted, wheat ears were counted, grains extracted and weighted. Results proved that migrating geese obviously damage and reduce yield of both winter wheat and permanent grasslands. Grazing reduced winter wheat ear development and grain weight. The high grazing pressure in winter wheat of 7.45 droppings/m² reduced yield by 10.8%. In the permanent grasslands geese presence indicator was 10.49±0.43SE droppings/m2 suggesting high grazing pressure reducing grasslands yield by 15.2%. [ABSTRACT FROM AUTHOR] |
