Specific harmful organisms whether singly or associated with plants shall not be introduced into the European Community. All activities which would involve these organisms are not allowed. The authorities can make under defined requirements an exception for activities for trial or scientific purposes and for work on varietal selections. The responsible body has to determine conditions which must be satisfied in the case of introductions, movements or activities, in order to ensure that there is no risk of harmful organism spreading. The legal basis is the Commission directive 95/44/EC transferred into German legislation by the Pflanzenbeschauverordnung. 相似文献

Recreationists who encounter more people than their normative tolerance for seeing others usually feel more crowded than those encountering fewer than their norm. This research note extends this observation–norm–evaluation relationship (e.g., encounter–norm–crowding) to other evaluations and indicators. Data were from a survey of anglers on the Gulkana National Wild River in Alaska (n = 288). Respondents who encountered more people than their norm felt more crowded than those encountering fewer than their norm. When impacts from other social indicators (e.g., camping within sight or sound of other groups, fishing area competition) exceeded user norms, crowding was higher and satisfaction with overall trip quality was lower than for those experiencing less than their norms. When impacts from resource indicators (e.g., litter, impacted campsites) exceeded norms, satisfaction with both environmental quality and trip quality were lower than for those experiencing less than their norms. The encounter–norm– crowding generalization, therefore, extended to other indicators and evaluations. 相似文献
