Grassland, woodland, and hedgerow enhancement for BNG in Cherwell

On a farm in Cherwell, we embarked on a project to enhance the existing grassland, improve woodland, and create new hedgerows. This BNG initiative serves as an offset for an ongoing development nearby in Fritwell.

We'll be enhancing the grassland through a multifaceted approach, including over-seeding and thoughtful management techniques like grazing and hay cutting. These efforts will help restore and bolster the grassland's ecological vitality. The current BNG commitment also extends to existing woodlands, where strategic thinning will enhance their overall structure. By doing so, we aim to promote a healthier and more robust woodland ecosystem.

Hedgerows are pivotal for improving connectivity within the landscape. Our approach to hedgerow management on this site involves early trimming, with laying as needed and appropriate in later years.  

The site

Habitat establishment

Fencing of the offsetting areas was carried out in the spring/summer of 2022. This is required to separate them from areas grazed by sheep through the spring and summer months. Thinning of the scrub took place in the autumn, after a breeding bird check. Much of the existing plants were relocated to the hedgerow areas helping to quickly establish good quality hedges of mature plants. Some good specimen standard trees (oak, beech, Sorbus) were left and some scrub species (hazel, blackthorn, hawthorn, holly) were relocated.

Habitat aftercare

Our dedicated land management strategy ensures the preservation and enhancement of the grassland ecosystem. Sheep will graze the grassland from June through July into the winter, with additional spring grazing each year. The primary objective of this grazing is to prevent the grassy biomass from smothering the precious wildflower species. To guarantee the balance, regular monthly reviews of the grazing process will be conducted, preventing overgrazing. Livestock exclusion, typically observed from late April to mid-July, will be adjusted based on the prevailing weather and growing conditions each year, all under the careful management of the landowner.

In Year 3, a thorough assessment of the grassland will guide us in determining whether a hay cut is needed. Periodic hay cuts may be necessary to manage grass density effectively. Additionally, we will undertake scrub thinning in Years 5, 10, 20, and 30 to curtail vigorous growth and promote a more diverse landscape structure. Professional contractors will handle this critical task.

The hedges on site will be trimmed annually to foster a bushy form. In Years 15 and 30, we will engage contractors to lay the hedges, reinforcing the ecological health and sustainability of Goose Farm.
