National action plan - Lowland dry acid grassland

 

Vision statement

Targets for restoration and re-creation of lowland dry acid grassland have not been met, and although maintenance targets appear to have been met in Scotland and almost met in England, this is as a result of improved survey information and masks a probable loss in real terms of the habitat across all four countries. Under-management is clearly the main cause of unfavourable condition, specifically under-grazing and abandonment. Scrub and bracken encroachment is the common result, sometimes together with invasive species problems. Lowland dry acid grasslands are still also affected by overgrazing and nutrient enrichment.

Underlying causes of under-management are still thought to be largely due to current agricultural economics and policies, exacerbated by problems such as BSE and Foot & Mouth disease, leading to a reluctance to keep stock (large stock in particular) on pasture perceived to have little nutritional value. In addition, the extent to which atmospheric nutrient deposition and climate change is affecting the composition of our grassland sites is a largely unknown quantity. Further landscape ecology studies aimed at spatial planning for defragmentation are also needed.

At the broad scale, the long-term solution undoubtedly lies in the area of major policy changes to further encourage environmentally friendly farming systems. Influencing livestock policy will be essential, together with positive niche marketing and branding schemes to favour environmentally friendly enterprises. Grazing schemes are proving their worth. Schemes such as GAP in England, and now PONT in Wales are producing very promising results, but now need much more secure financial backing.

Latest UK status

Value Units Accuracy of estimate Date assessed Comments
61646 Hectares Partial survey 2005 No new data sources for habitat extent have been made available since 2005, CS2007 is not sufficiently accurate (sample size too small) for this habitat. Therefore the 2005 value is still the best estimate available. This figure was based upon survey, but adjusted for likely losses. It is probable that losses have continued since 2005 (see trend - declining, but slowing), therefore this figure is probably an overestimate. LBAP data was not used in the 2005 estimates; however, LBAP submissions were used to determine the likely trend.

Latest UK trend

Trend Accuracy of estimate Date assessed Comments
Declining (slowing) Best guess 2008 There is still no UK-wide co-ordinated programme of habitat surveillance on which assessments of changes in extent and condition can be based. CS2007 results are not sufficiently accurate as the sample size for this habitat was too small.
From comments and data provided by LBAPs, local teams and projects it appears that there is still an on-going loss of extent and condition of (see T1 and T2). Although considerable efforts have been made to improve management (T3) and to restore lowland dry acid grassland (see T4), the majority of this area will be restoration in progress which may take many years to achieve priority habitat status; re-creation of habitat through habitat expansion (T5) will take even longer. The exception to this may be where restoration is achieved through conifer removal, which may provide a more rapid return to LDAG status. There are currently limited data available on the success or otherwise of AE restoration/expansion initiatives, therefore it has to be assumed that only a small percentage of the area under restoration / expansion has currently achieved BAP status. This percentage would be expected to rise over the next decade and beyond, with continuing favourable management.

Targets

Code Text UK Status Assessment date
T1 Maintain the current extent of Lowland Dry Acid Grassland in the UK. (Target represents no loss of BAP habitat). Target not achieved 2008
T2 Maintain at least the current condition of Lowland Dry Acid Grassland. Some progress (on schedule) 2008
T3 Achieve favourable or recovering condition for 29,220 ha of Lowland Dry Acid Grassland by 2010. Some progress (behind schedule) 2008
T4 Restore 313ha of Lowland Dry Acid Grassland from semi-improved or neglected grassland, which no longer meets the priority habitat definition by 2010. Some progress (on schedule) 2008
T5 Re-establish 363ha of grassland of wildlife value from arable or improved grassland by 2010. Some progress (behind schedule) 2008
T6 270 ha (75%) of re-established area to be adjacent to existing Lowland Dry Acid Grassland or other semi-natural habitat by 2010. (Refer to T5) Some progress (behind schedule) 2008
T7 180 ha (50%) of re-established area to contribute to resultant habitat patches of 6 ha or more of Lowland Dry Acid Grassland by 2010. Where ever practicable bigger patches should be created. (Refer to T5) Some progress (behind schedule) 2008
