• Strategic level understanding of visitor use of European sites across whole county. • Current visitor levels, and profile of visitors, e.g. activities being undertaken to help inform the impact on landscapes/wildlife. • Understanding the ‘catchment’/‘draw’ of sites and how these relate to future population levels. • ->appropriate mitigation to facilitate suitable new development .
• Interviews with a random sample of visitors on site. • 40 survey points – 2 days, 16 hours at each location. • Access points to sites where recreation and wildlife coincide. • Timing of surveys to coincide with designated interest – may/may not coincide with peak of people. • Includes some seasonal repeats. • Range of questions for visitor profiling – activity, frequency of visit, reasons for visiting. • Routes. • Home postcode. • Tally count of people entering and leaving sites.
Tally counts: • 6 k groups were recorded entering or leaving sites -> 14 k adults, 2 k minors and 3 k dogs. • But variable between survey points and areas.

• Highest numbers were recorded at Holkham and Horsey Gap -> c.1,900 people recorded in survey ~ 120 people per hour. • Lowest: total of 22 people at Breydon Water winter survey. ~ 1.4 people per hour. • Identify sites with most and least current pressures purely in terms of footfall. -> High visitors = pressure? High profile sites can be well managed to lessen impact.
Similarity index
• Using only the tally data group sizes
• Clustering
• ~1,300 interviews conducted. • Separate those on holiday and those from home – important for local housing increases. • Holiday-makers accounted for nearly half of interviewees at the North Coast and Broads.
Why? • Some activities have greater impacts at certain sites -> implications for management
Visit duration: • The Broads c. 33% of interviewees visiting for more than 4 hours in the Broads. • At Roydon c. 33% of interviewees visiting for less than 30 minutes. • Visiting duration less, but may or may not result in greater impact. • Will also depend on where is the impact….
• Home postcodes of interviewees. • Interviewees on holiday only.
• Only half of interviewees lived in Norfolk.
Visitors from home only.
• Average linear distance was 24km. • Median linear distance was 11 km (50% live within this radius).
• Using visitor data to consider future visitor pressures. • Currently, 400 k residential properties in Norfolk. • Future plan period, show potential of 66 k new dwellings -> 16% increase. • We plot both to examine increases around each site.

• However, the ‘catchment’ or ‘draw’ of sites can be different. • Visitor curves –> likelihood of visiting decreasing with increase distance away from site.
• Include new housing in the curves. • Which developments are likely to result in highest increases in visitors. • ‘Future interviewees’ – 233, an increase of just under 14% -> overall housing increase 16%.
• Future interviewees by authority. Future Interviewees (Norfolk residents)

• Catchments specific to sites’ • Various factors such as attractiveness, facilities etc will influence how far people will travel
• • •
What level of housing leads to impact? What evidence? Solutions?
• Around 80,000 new dwellings current plan period • 11 local authorities • 3 SPAs (all coastal)
● Evidence base for HRA Initial review/scoping ● Visitor surveys ● Bird disturbance work ● Visitor & bird modelling work (2010-2014):
Behavioural - understand how individual animals respond to changes in the environment - Foraging behaviour – food competition - Response to disturbance – energetic costs, lost feeding time etc - Decision rules – trading-off costs and benefits
What are the population consequences - Site Management/Strategic Planning Issues

Models provide powerful insight but.. Models only possible: ● For small part of Solent ● For a small selection of species Difficult assumptions: ● Extent to which birds can move freely within the site
● Intake rate when feeding at night ● Extent to which birds knowledge is perfect – how well can they really select the best places to be
• Developer contributions of £272 per dwelling, collected within 5.6km radius (zone identified from postcode data). • Funding in a central pot. • Used to fund a delivery officer, warden team, dog walking project, GI, monitoring programme.

Thames Basin Heaths & SANGS • 41 SANGs (excluding ones linked to specific large developments) • Variation in size, character, habitat • The total area of SANGs is 942ha; max=86ha. • Area of SANGs equivalent to 11% area of SPA
Nightjar trends No significant increase or decrease in nightjar numbers

Nightjar numbers have increased on Purbeck sites while numbers on other sites have shown little change
• Norfolk wide surveys are unique in scale and number of European sites covered simultaneously. • Allow direct comparison between sites and indication of cumulative impacts of growth. • Visitor data provides the key evidence for HRAs and mitigation. • Clear links for Norfolk Valley Fens, Roydon, Brecks with recreation and local housing. Marked changes predicted particularly for the Brecks. Other areas have draw over wide area. Changes in access predicted across all sites (14%). • Survey provides baseline for mitigation to be established and tailored to relevant sites.
