Providing foraging resources for bumblebees in intensively farmed landscapes
Richard F. Pywell,E. A. Warman,Claire Carvell,Tim H. Sparks,Lynn V. Dicks,D. Bennett,Allan Wright,C.N.R. Critchley,A. Sherwood +8 more
TL;DR: Examination of the long-term effectiveness of four different management strategies to enhance and restore bumblebee foraging habitat on arable field margins in two regions with markedly contrasting landscape structure, farming systems and amount of semi-natural habitat found the removal of field margins from the cropping system was the best strategy.

Effectiveness of new agri-environment schemes in providing foraging resources for bumblebees in intensively farmed landscapes
Richard F. Pywell,E. A. Warman,Lucy Hulmes,S. Hulmes,P. Nuttall,Tim H. Sparks,C.N.R. Critchley,A. Sherwood +7 more
TL;DR: There was evidence that richness of the bumblebee assemblage at the 10 × 10 km square scale was positively correlated with land use heterogeneity, the proportion of grassland, and the abundance and richness of dicotyledon flowers.

Enhancing diversity of species-poor grasslands: an experimental assessment of multiple constraints
Richard F. Pywell,James M. Bullock,J. R. B. Tallowin,Kevin J. Walker,E. A. Warman,Greg Masters +5 more
TL;DR: This work investigates biotic and abiotic constraints on diversification by manipulating seed and microsite availability, soil fertility, resource competition, herbivory and deficiencies in the soil microbial community to find the most effective and reliable means of increasing grassland diversity.

The importance of former land use in determining successful re-creation of lowland heath in southern England
TL;DR: In this paper, the success of heathland re-creation on 37 former arable, improved grassland and conifer plantation sites in southern England, UK was assessed, and it was concluded that conifer removal provides the most practical and cost-effective means of re-creating Calluna heath on former heath, although further research is required to assess the effect of litter removal and the rate at which heather seed banks decline following conversion to forestry.

The potential for lowland heath regeneration following plantation removal
Richard F. Pywell,Robin J. Pakeman,E.A Allchin,Nigel A. D. Bourn,E. A. Warman,Kevin J. Walker +5 more
TL;DR: In this article, the authors examined the size, composition and distribution of the seed bank under conifer plantations of different ages at two important heathland sites in Britain and found significant, exponential declines in the mean density of viable heather seeds with plantation age at both sites.
