S.L. 433.3 ст. 12BGuidelines for surveys for the purposes of the recognition of protected zones.

(1) In carrying out surveys for the purposes of the recognition of protected zones, the Directorate shall, in respect of harmful organisms of the animal kingdom other than nematodes, relevant to forestry plants or plant products, which attack crops normally grown in the open air, take account of the following guidelines:

(a) the survey shall be carried out in the relevant zone;

(b) the survey methodology shall be based on a recording plot method, comprising the following elements: a network of observation points shall be established following a systematic grid covering the entire relevant zone; the following parameters of each point shall be registered: number, actual latitude and longitude coordinates, topography, and, where appropriate, a site description shall be made. Where appropriate, additional information may be collected; the observation points may be marked; maps for representation of observation points may be produced;

(c) the following criteria shall be used to decide the suitability of an observation point:

(i) in general the point must be sufficiently large to allow selection of a point;

(ii) in general the point shall be located in the above-mentioned area to allow the appropriate assessment operations; and

(iii) in special cases, where appropriate, other points shall be selected, such as on sites where the risk of potential introduction of any harmful organism of concern in an area is high;

(d) where appropriate, meteorological, especially precipitation and temperature, and edaphic data shall be recorded, preferably on the site of the observation point, but may also be obtained from a nearby station where these variables are regularly measured. Extreme events, such as drought, heavy rain, and other similar extreme meteorological occurrences, which are likely to influence the observations shall also be recorded;

(e) the survey, at each observation point shall be at least:

(i) concentrated on a representative number of units of plants or plant products;

(ii) concentrated on one or more of the main host plants or plant products of any harmful organism of concern; where appropriate other hosts shall also be included;

(iii) comprising visual inspections to determine the presence of symptoms or signs of any harmful organism of concern, carried out at a time when such symptoms or signs would be expected to be at their maximum; and

(iv) in cases of doubt, laboratory testing of samples; and

(f) where appropriate, at the observation points, traps which attract the relevant organisms shall be used; the type and number of traps to be used as well as the method of trapping shall take into account the biology of the pest.

(2) Any future measure, which is appropriate to ensure that the conditions laid down in regulation 4 are met, may be taken.

(3) The Director may issue guidelines in respect of harmful organisms other than those referred to therein, once the necessary technical information is available.
