Grassland maintenance, restoration and expansion headline figures
Figures correct Jan 2017
Maintenance is maintain current extent, i.e. though management such as grazing, mechanical management like harrowing etc.
Restoration is management to improve quality towards priority habitat status. This may be through controlling species such as bracken or scrub or through seed addition where propagules are required to enhance the sward.
Expansion is habitat creation in its most basic form i.e. from scratch or very low grade habitat (very nearly equivalent to the use of the term ‘creation’ which is often used in the context of creating a lowland grassland from arable land (arable reversion). This often involves seed addition).

Maintain extent – rush management • Expanded the herd from 6 to 33 Konik ponies and their movements around the reserve are being monitored using GPS collars

Maintain extent – rush management • Expanded the herd from 6 to 33 Konik ponies and their movements around the reserve are being monitored using GPS collars
• Monitoring height and density of rushes and forb richness:- rush density July 2014: ‘grazed & mown’ < ‘grazed’ < ‘mown’ = ‘unmanaged’
• Numbers of lesser butterfly orchids increased from 131 in 2014 to 204 in 2015.

• In Fermanagh over 100ha of sp-rich grassland has been identified

Grassland restoration –calaminarian grassland
Mini-digger scraping back soil © Naomi Waite | Northumberland Wildlife Trust
• Scrapes were created using a mini-digger scraping off topsoil to a depth of 5-50cm.
• Williamston SSSI:• 7 plug plants / sq m transplanted inc. mountain pansy Viola lutea, alpine pennycress Noccaeacae rulescens and spring sandwort Minuartia verna.
• Burnfoot Shingles SSSI:• No plug plants used• One year on... low re-growth of non-calaminarian species, and alpine pennycress and spring sandwort were found in the scrapes
Grassland restoration –seed inoculation and plug planting
• Seed from 21 wildflowers has been collected from neighbouring sites to enhance the arable reversion that has been undertaken at Winterbourne Downs, inc:
• devil’s-bit scabious • dropwort • saw-wort • kidney vetch• common-rockrose • wild thyme • autumn gentian • yellow-wort • common-spotted orchid • fragrant orchid • pyramidal orchid
3500 plug plants have been transplanted and seed has been sown into shallow scrapes created by volunteers
Orchids were recorded in 4 fields for the first time in 2015

Grassland restoration – earth mounds for invertebrates and reptiles

• 14 mounds were created around a flat meadow at Blakehill Farm in Wiltshire in autumn 2014.
• Monitoring in the summer of 2014 and 2015 found no conclusive evidence that invertebrates were burrowing into the mounds
• But, as the mounds vegetated quickly, invertebrates, particularly hoverflies and bees were foraging on the mounds
Grassland expansion – monitoring indicator species• Restored a 2ha grassland by changing the management regime to hay-making in 2014 and spreading fresh brush-harvested seed in 2015

Meadow management and re-seeding
• Restored a 2ha grassland by changing the management regime to hay-making in 2014 and spreading fresh brush-harvested seed in 2015
• The number of positive indicator species has increased
• Yellow rattle is now present from the donor site, and common cat’s-ear, meadow buttercup, self-heal and black knapweed have all increased in frequency
