5.15.2 Relevance of the Economicbenefits of <strong>visitor</strong> use indicatorThis indicator requires the development of a socio-economicstudy and aims to answer two key questions :• What are the economic benefits of <strong>visitor</strong> use (in termsof employment and added value) of the <strong>MPA</strong> for economicactivity in neighbouring areas.• To what extent can <strong>visitor</strong> use generate revenues tofund the cost of <strong>MPA</strong> protection?The scope of monitoring this indicator extends greatlybeyond the boundaries of the <strong>MPA</strong>. In the same wayas the issue of conservation, inclusion of this economicdimension is vital for the definition of sustainable tourismin the <strong>MPA</strong>.Multidisciplinary indicator implementation inLes Calanques National Park (France).The Liteau FHUVEL programme (Fréquentation Humaineet Vulnérabilité Écologique du Littoral - Visitor use andEnvironmental vulnerability of the Coast) for the 2009-2012 period primarily aims to develop a cross-disciplinarymethodology to assess the vulnerability of the remarkablecoastal ecosystems (coralline, Posidonia grass bedsand Trichoptera) and to identify the factors responsiblefor that vulnerability to prioritise conservation or evenrestoration needs. By crossing indicators, FHUVELinterlinks biological data with <strong>visitor</strong> and use data toidentify sociological and ecological tolerance thresholdsand move towards carrying capacity indicators.The workshop sites are expected to provide concretecontributions to help develop management and decisiontools for use in Les Calanques National Park, takingaccount of <strong>uses</strong>, social representations and the necessaryprotection of nature.Coralline formation, Les Calanques National Park (France).© Credit: Olivier BianchimaniThe benefit of an initial evaluation of <strong>visitor</strong>use and biocenoses to assess the impactof a new development: the example of theTables diving site in the Posidonia grassbeds of Cap d’Agde marine protected area(France).The Tables site is a small, rocky submarine area onlya few hundred metres from the cliffs of Cap d’Agde. Itconsists of a set of volcanic tuff slabs with numerousfaults, caves and overhangs that are home to extremelydiverse fauna and flora greatly sought-after by divers.At the Tables site, the problem of <strong>visitor</strong> use (diving andmooring) and its impact was addressed relatively earlyon. Studies were initiated in 1999 (Musard, 1999; Payrot,2001) and evidenced the significant pressure generatedby deep-sea diving on certain coastal sites of Agdeincluding the Tables, with numbers in summer estimatedat 8,500 dives and some 850 mooring boats. Surveyswere also conducted with local diving clubs and theopinions obtained were unanimous about the problem of"overcrowding" in the Tables site. Plans were thereforemade in 2005 to install seven Harmony-type ecologicalmooring buoys at the site, following an initial analysis tobe able to subsequently monitor and measure the effectsof the new facilities on marine biocenosis restoration. Thewhite gorgonian seafan Eunicella singularis was selectedas the indicator species owing to its representativenessin the study zone and because it is a sessile organismwhich, by definition, cannot flea pressure.The study was conducted in 2010 and 2012 by theAssociation ADENA. After only five years, the restorationof the white seafan population was already taking placeat the Tables site. Analyses showed a clear growth in thepopulation between 2005 and 2010 which continued until2012, together with development in the coverage of rockyareas. The high densities of young gorgonians reflectthe area's potential for development and regeneration.With an increase in densities of large gorgonians too, theresults concerning the natural restoration of white seafanare extremely positive, both in terms of the conservationbenefits of this kind of mooring and the willingness ofdiving clubs, as stakeholders of the "Posidonies duCap d’Agde" Natura 2000 site, to use the facilities forsustainable protection.Reference : Blouet S., Chéré E., Dupuy de la Grandrive R.,Foulquié M. 2010.

6. Implementing indicatorsOnce the indicators have been selected and the protocols tailored to your <strong>MPA</strong>, their implementation must beorganised. Certain difficulties can then arise: the need to alter protocols during the study, varying data quality yearover year, difficulties making comparisons, loss of information, lack of coordination, lack of observatory ownershipby the management team, dilution of responsibilities, etc.A few simple guidelines can help restrict these implementation difficulties.6.1 Preparing and harmonising fielddata report formsCertain data collection materials need to be preparedand specifically adapted to the features of the <strong>MPA</strong> andthe aim of the study. This is particularly the case with :• count report forms (passenger arrivals, boats in mooringsites, flows of cyclists on paths, etc.);• field data records (records of offences, weather conditions,etc.);• survey questionnaires (multiple-choice or interviews).The format of these collection tools should be harmonised(same counting typologies, same organisation ofmultiple-choice questions, etc.), to facilitate their useand subsequent data processing and archiving.6.2 Installing and testing technicaltoolsCertain data collection means involve technologies ofvarying degrees of complexity, so it is important to testthem prior to actual use.• For overflights, the flight plan must be prepared withthe pilot, all the flight authorisations must be obtained,the condition and range of the camera must be checked,and photo-interpretation limits must be assessed;• Handheld counters should be rounded up and labelled,as they can quickly get lost;• The installation plan for the network of automatic counterson paths must be defined, the equipment installed(acoustic slab sensor, pyro-electric sensor or magneticloops) during a quiet period, and checks must be doneto ensure the counters and recording equipment workcorrectly.6.3 Testing protocolsIt is advisable to test the data collection protocols in realsituations. Their feasibility must be checked with theassurance that nothing will hinder the smooth conductof surveys, that respondents understand the multiplechoicequestions, that entities holding data are preparedto disclose it, that automatic counters work, etc. Countingprotocols should ideally be tested during averagelybusy periods and not during the low season.6.4 Organising and standardisingindicator implementationTo guarantee the sustainability of the study and datausability, protocols must be formally documented and arecord should be kept of the conditions in which they areimplemented each year. Managers should :• draw up a clear, technical compendium of methodssetting out the collection protocols for each indicatorin detail to guarantee reproducibility;• define a schedule of monitoring operations each year.6.5 Forming a teamForming a team motivated by the issues of <strong>visitor</strong> useand responsible for implementing the indicators in the<strong>MPA</strong> is a key factor in the success of the study. It is thereforeadvisable to :• Assign <strong>MPA</strong> employees to the study and provide eachteam member with training. The team should be involvedin the <strong>visitor</strong> use monitoring project right fromthe start. They can make valuable contributions invarious areas due to their in-depth knowledge of thefield. The protocol tests are an excellent opportunityfor training using the compendium of methods as learningmaterial.• Keep involvement of trainees to a minimum as this candemand a considerable training effort and restrict thestudy in terms of knowledge of the <strong>MPA</strong> and communicationwith users; it can also have a disincentiveeffect on the team managing the study.• Appoint a lead coordinator to oversee the entire study(indicator definition and adjustment, verification of collecteddata, schedule preparation, participation in datareporting). Different people may be put in charge ofcertain aspects (counts, data capture, etc.), but theirrespective tasks shall not replace the lead coordinator'srole.
