Prescribed Burning

In a 28-year study, annual spring burning of grassland in Sweden did not affect populations of oxeye daisy. However, there are two considerations where prescribed fire is planned. First, fire exposes bare, mineral soil and favors the germination and establishment of oxeye daisy seeds and seedlings. Second, fire may increase or decrease nitrogen in the soil. Decreased nitrogen favors oxeye daisy over forage grasses in competitive interactions and increased nitrogen may have the opposite effect. To reduce the risk of increased oxeye daisy after prescribed burning, deferred grazing and herbicide management are recommended. Where there are no competitive plants or in forested plant communities where prescribed fire is planned, herbicide management and re-vegetation are recommended along with deferred grazing.
