What is the long term impact of mowing dwarf scrub heath on ecosystem resilience in mountains, moorland, and heath?
Summary of the Research Question / Evidence Need:
Dwarf shrub heath was often traditionally grazed and burnt, but with changes in grazing practice for example the loss of cattle and landowner reluctance to burn due to regulatory requirements, potential damage to wet heath and bog, and public perception, mowing is increasingly advocated to break up large swards and create firebreaks and access for stock. Lack of fire-induced Calluna germination coupled with mulching with unharvested material may change the nature of the vegetation. A review of current knowledge and possible experimental manipulation is required to enable appropriate advice to be provided.

What is the long term impact of planting trees on shallow peats and or organo-mineral soils on carbon storage and sequestration in soil and vegetation?
Summary of the Research Question / Evidence Need:
Planting trees on deep peat soils is thought to lead to significant loss of soil carbon, but the effect on soil carbon of planting on grasslands over organo-mineral soils, including peats of up to 50 cm, and in particular the overall carbon balance in the long term, is less well understood.

What is the long time impact of climate change on the different types of semi-natural grassland?
Summary of the Research Question / Evidence Need:
Grasslands are affected by climate change, such as from summer droughting and hydrological changes, but more research is needed on the long term effects on species composition of different types of grassland.

What is the long-term trend of soil fertility and base-status in montane habitats and what are the drivers of change?
Summary of the Research Question / Evidence Need:
Upland soils once supported Neolithic agriculture but would struggle to grow crops today. Land management, climate change and acid rain all affect the evolution of upland soils but is poorly documented. The use of lime on upland pasture and ffridd may have been widespread in historic time but is now rare. A review of upland soil development and likely changes under future landscape options is required to enable an understanding of this resource.

What is the origin of the of the slipper limpet (Crepidula fornicata) in North Wales?
Summary of the Research Question / Evidence Need:
We are aware that an established population of the slipper limpet (Crepidula fornicata) is in the Menai Strait and south east Anglesey due to a number of records from 2020. NRW wish to understand more about the method of introduction of this species to North Wales. An established population exists in Milford Haven and Northern Ireland but it is yet unclear whether this species has arrived through natural spread or whether it was introduced through a specific introduction event, either a new event or whether the species has been present since the previous introduction event of 2006. This project could involve genetic analysis and an examination of pathways. Evidence on the method of introduction is important to ensure existing biosecurity protocols are adequate and will help target pathways for potential future introductions to an area.
