SSSI condition assessment mechanisms Consideration should be given to revisit notification criteria for designated sites, particularlythose now known to hold significant <strong>in</strong>vertebrate assemblages. It would be useful to explicitlyrelate these <strong>in</strong>terest features to the conditions and processes required to susta<strong>in</strong> them. Conservation objectives should be specifically tailored to reflect the requirements of priorityspecies known or assumed to be present, or capable of be<strong>in</strong>g present with changes <strong>in</strong>management, <strong>in</strong> light of what is now known about the requirements for priority species <strong>in</strong><strong>Breckland</strong>. For Common Standards Monitor<strong>in</strong>g, condition assessment criteria for NVC plant communitiesshould be revised, and localised, to reflect the conditions and processes required by keyassemblages of priority <strong>Breckland</strong> species. A small percentage of heather, <strong>in</strong>clud<strong>in</strong>g seedl<strong>in</strong>gs and pioneer heather or the appropriateconditions for their regeneration should be considered sufficient qualification of the<strong>European</strong> feature (i.e. heather heathland, or H1 community of NVC) to be <strong>in</strong> appropriatecondition.Strategic plann<strong>in</strong>g and creation of networks The <strong>Biodiversity</strong> Audit <strong>Commission</strong><strong>in</strong>g Group should cont<strong>in</strong>ue to coord<strong>in</strong>ate an <strong>in</strong>tegratedapproach to biodiversity delivery. Organisations should operate to ma<strong>in</strong>ta<strong>in</strong> and enhance cross-border <strong>in</strong>tegration and jo<strong>in</strong>twork<strong>in</strong>g, both with<strong>in</strong> and between organisations, to ensure collaborative work<strong>in</strong>g at thelandscape scale, to co-ord<strong>in</strong>ate efforts and understand<strong>in</strong>g and to share best practice. It is important that both Local County Records Centres cont<strong>in</strong>ue to liaise and ma<strong>in</strong>ta<strong>in</strong> the<strong>Breckland</strong> <strong>Biodiversity</strong> Audit database as an updated and live resource, available tomanagers for strategic plann<strong>in</strong>g. Ensure Natural England cont<strong>in</strong>ues to target <strong>Breckland</strong> for agri-environment fund<strong>in</strong>g, withan emphasis on options and <strong>in</strong>itiatives which support priority species and create andma<strong>in</strong>ta<strong>in</strong> resilient ecological networks. Opportunities should be taken to strategically buffer and l<strong>in</strong>k exist<strong>in</strong>g SSSI units <strong>in</strong>to largecontiguous networks wherever possible, allow<strong>in</strong>g <strong>in</strong>tegrated graz<strong>in</strong>g management andenhanced populations of specialist assemblages. Connectivity among dispersed sites could be achieved by provid<strong>in</strong>g juxtaposition of grassstrips, disturbed ground, and cultivated field marg<strong>in</strong>s along exist<strong>in</strong>g track-ways. Connectivity both with<strong>in</strong> and across the forest landscape may be achieved by creat<strong>in</strong>gwide, physically disturbed ‘<strong>in</strong>vertebrate super-highways’, that would provideopportunities for spatially cont<strong>in</strong>uous un-shaded conditions, population percolation andflanked by nectar rich ungrazed flower rich verges. Connectivity elements may be provided by revitalis<strong>in</strong>g stock drov<strong>in</strong>g activity to providecross l<strong>in</strong>ks with these ‘super-highways’.204
