This month is when the first year's wildflower monitoring can take place. Percentage of wildflower coverage, presence and frequency of species, sward height and negative indicators are all observed and recorded by Rangers. This builds a picture of how potentially successful the seed sowing work, and winter grazing has been. Some species can take up to 7 years to become well established, whilst others can become dominant within 2 years. Therefore, the natural balance of species in the meadow can take many years to settle down. At this stage we can monitor how well the new wildflower rich grassland is being cared for which provides a likely trajectory for success. In year one, on average across the 86ha of species poor grasslands sown in North Devon, the coverage of wildflowers went from 2% to 30%.
Through July and August, the Rangers have been taking advantage of dry sunny days to collect seed from existing wildflower rich grasslands. This is done with either a brush harvester, seed vacuum or with our hands depending on, what species is being collected, the sensitivity of the wildlife at the site and the accessibility. Rangers harvested 200kg of seed during July and August. The seed is dried in barns for 3-6 days and the chaff (grass stalks, seed husks and other material) is separated from the seed through sieves. The seed is then stored and labelled ready for use in the Autumn.
Thank you to Bumble Conservation Trust for networking the National Trust with local landowners. Thank you to our neighbours who allowed us to harvest seed from their meadows. Thank you to Natural England for giving us permission to carefully take seed from valuable places such as Braunton Burrows.
