The use of natural regeneration was one of the main features making CCF attractive to foresters due to potential savings in planting costs and
use in site-adapted stock. However, due to excessive deer pressure in the UK, natural regeneration is not achievable without expensive protective measures. This is one of the reasons why other methods to achieve CCF such as underplanting are unpopular due to their in-achievability without a serious culling plan.
The absence of environmental impacts linked to clear felling is one of the major benefits of a CCF system. Factors such as soil erosion, disturbance of the water table, water run-off and nutrient loss would be non-existent. Furthermore, with the need for climate change resilience in woods, the increased resilience to wind damage, late spring frost, drought and invasive ground vegetation are major potentials to consider.
CCF is particularly relevant when working in ancient woodland or sensitive environments where too great an impact could dramatically change ecosystem dynamics, creating a disadvantageous environment for certain floral or faunal communities. For instance, the much-loved bluebells grow best under deciduous canopies where they rely on the canopy opening to get a head start to then be in an advantageous position once the canopy closes. Many other ancient woodland plants rely on competitive traits linked to shade tolerance to thrive, whilst light-demanding species usually attract undesirables such as brackens and brambles which would outcompete more specialised floral communities.
