the risk factor(s), indicating the risk levels and corresponding relative risks and proportions of host plant population. For column 1: Indicate the name of the geographical area, outbreak number or any information that allows identification of this demarcated area (DA) and the date when it was established. For column 2: Indicate the size of the DA before the start of the survey. For column 3: Indicate the size of the DA after the survey. For column 4: Indicate the approach: Containment (C). Please, include as many rows as necessary, depending on the number of DA per pest and the approaches these areas are subject to. For column 5: Indicate the zone of the DA where the survey was carried out, including as many rows as necessary: Infected zone (IZ) or buffer zone (BZ), using separate rows. When applicable, indicate the area of the BZ where the survey was carried out (e.g. last 20 km adjacent to the BZ, around nurseries, etc.) in different rows. For column 6: Indicate the number and the description of the survey sites, by choosing one of the following entries for the description: 1. Open air (production area): 1.1 field (arable, pasture); 1.2. orchard/vineyard; 1.3. nursery; 1.4. forest; 2. Open air (other): 2.1. private gardens; 2.2. public sites; 2.3. conservation area; 2.4. wild plants in areas other than conservation areas; 2.5. other, with specification of the particular case (e.g. garden centre, commercial sites that uses wood packaging material, wood industry, wetlands, irrigation and drainage network, etc.); 3. Physically closed conditions: 3.1. greenhouse; 3.2. private site, other than greenhouse; 3.3. public site, other than greenhouse; 3.4. other, with specification of the particular case (e.g. garden centre, commercial sites that uses wood packaging material, wood industry). For column 7: Indicate the months of the year when the surveys were carried out. For column 8: Indicate the chosen target population providing accordingly the list of host species/genera and area covered. The target population is defined as the ensemble of inspection units. Its size is defined typically for agricultural areas as hectares, but could be lots, fields, greenhouses, etc. Please justify the choice made in the underlying assumptions. Indicate the inspection units surveyed. ‘Inspection unit’ means plants, plant parts, commodities, materials, pest vectors that had been scrutinised for identifying and detecting the pests. For column 9: Indicate the epidemiological units surveyed, indicating their description and unit of measurement. ‘Epidemiological unit’ means a homogeneous area where the interactions between the pest, the host plants and the abiotic and biotic factors and conditions would result into the same epidemiology, should the pest be present. The epidemiological units are a subdivision of the target population that are homogenous in terms of epidemiology with at least one host plant. In some cases the whole host population in a region/area/country may be defined as epidemiological unit. They could be Nomenclature of territorial units for statistics (NUTS) regions, urban areas, forests, rose gardens or farms, or hectares. The choice shall be justified in the underlying assumptions. For column 10: Indicate the methods used during the survey including the number of activities in each case, depending on the specific legal requirements of each pest. Indicate with N/A when the information of certain column is not available. For column 11: Indicate an estimation of the sampling effectiveness. Sampling effectiveness means the probability of selecting infected plant parts from an infected plant. For vectors, it is the effectiveness of the method to capture a positive vector when it is present in the survey area. For soil, it is the effectiveness of selecting a soil sample containing the pest when the pest is present in the survey area. For column 12: ‘Method sensitivity’ means the probability of a method to correctly detect pest presence. The method sensitivity is defined as the probability that a truly positive host tests positive. It is the multiplication of the sampling effectiveness (i.e. probability of selecting infected plant parts from an infected plant) by the diagnostic sensitivity (characterised by the visual inspection and/or laboratory test used in the identification process). For column 13: Provide the risk factors in different rows, using as many rows as necessary. For each risk factor indicate the risk level and corresponding relative risk and proportion of host population. For column B: Indicate the details of the survey, depending on the specific legal requirements for each pest. Indicate with N/A when the information of certain column is not applicable. The information to be provided in these columns is related to the information included in the column 10 ‘Detection methods’. For column 18: Indicate the number of trapping sites in case this number differs from the number of traps (Column 17) (e.g. the same trap is used in different places). For column 21: Indicate the number of samples found positive, negative or undetermined. ‘Undetermined’ are those analysed samples for which no result was obtained due to different factors (e.g. below detection level, unprocessed sample-not identified, old, etc.). For column 22: Indicate the outbreak notifications of the year when the survey took place for findings in the buffer zone. The outbreak notification number does not need to be included when the competent authority has decided that the finding is one of the cases referred to in Articles 14(2), 15(2) or 16 of Regulation (EU) 2016/2031. In this case, please indicate the reason for not providing this information in column 25 (‘Comments’). For column 23: Indicate the sensitivity of the survey, as defined in International Standard for Phytosanitary Measures (ISPM 31). This value of the achieved confidence level of pest freedom is calculated based on the examinations (and/or samples) performed given the method sensitivity and the design prevalence. For column 24: Indicate the design prevalence based on a pre-survey estimate of the likely actual prevalence of the pest in the field. The design prevalence is set as a goal of the survey and corresponds to the compromise the risk managers are making between the risk of having the pest and the resources available for the survey. Typically, for a detection survey a value of 1 % is set.
