Woodland Predation Shadow for Waders v2

<span style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>The data describes the potential area of impact of areas of woodland upon breeding wading birds due to the predation shadow associated with the woodland. The purpose is to support users of the ‘Guidance to help inform when an upland breeding wader survey is needed and when woodland creation is likely to appropriate’ (Defra/FC/NE, 2024). All National Forest Inventory 2021 (NFI 2021) woodland was used in this layer. The definition of woodland included in the NFI is as follows: A minimum area of 0.5 ha under stands of growing trees greater than 20m in width, with a canopy cover of at least 20% comprised of trees at least 5 metres in height or having the potential to achieve this. This definition relates to land use, rather than land cover, so newly established woodland, integral open space and felled areas within existing woodland that are awaiting restocking are included as woodland. A 500m buffer around woodland was created, covering the full extent of the shadow, while a 500m inwards buffer of the predation shadow reveals areas which are 500m from open land. This is then split into Zone 1 and Zone 2. Zone 1 represents land further than 500m away from open land that is already covered by an existing predation shadow. woodland creation in Zone 1 is unlikely to significantly encroach into open land. Zone 2 represents the existing predator shadow and may, or may not be land which supports waders. It lies within 500m of open land and existing NFI woodland. New woodland creation in Zone 2 will result in encroachment of predator shadow across open land. The data covers the area in scope of the wader guidance - Northumberland, Durham, Cumbria, Yorkshire, Lancashire, North York Moors and the Peak District.</span>
