Parties undertake to give special attention to the protection of areas that are of importance for the migratory species specified in Appendices II and III and which are appropriately situated in relation to migration routes, as wintering, staging, feeding, breeding or moulting areas. 4. The Contracting Parties undertake to coordinate as appropriate their efforts for the protection of the natural habitats referred to in this Article when these are situated in frontier areas. CHAPTER III Protection of speciesArticle 5Each Contracting Party shall take appropriate and necessary legislative and administrative measures to ensure the special protection of the wild flora species specified in Appendix I. Deliberate picking, collecting, cutting or uprooting of such plants shall be prohibited. Each Contracting Party shall as appropriate, prohibit the possession or sale of these species. Article 6Each Contracting Party shall take appropriate and necessary legislative and administrative measures to ensure the special protection of the wild fauna species specified in Appendix II. The following will in particular be prohibited for these species:(a) all forms of deliberate capture and keeping and deliberate killing; (b) the deliberate damage to or destruction of breeding or resting sites; (c) the deliberate disturbance of wild fauna particularly during the period of breeding, rearing and hibernation, in so far as disturbance would be significant in relation to the objectives of this Convention; (d) the deliberate destruction or taking of eggs from the wild or keeping these eggs even if empty; (e) the possession of and internal trade in these animals, alive or dead, including stuffed animals and any readily recognizable part or derivative thereof, where this would contribute to the effectiveness of the provisions of this Article. Article 71. Each Contracting Party shall take appropriate and necessary legislative and administrative measures to ensure the protection of the wild fauna species specified in Appendix III. 2. Any exploitation of wild fauna specified in Appendix III shall be regulated in order to keep the populations out of danger, taking into account the requirements of Article 2. 3. Measures to be taken shall include:(a) closed seasons and/or other procedures regulating the exploitation; (b) the temporary or local prohibition of exploitation, as appropriate, in order to restore satisfactory population levels; (c) the regulation as appropriate of sale, keeping for sale, transport for sale or offering for sale of live and dead wild animals. Article 8In respect of the capture or killing of wild fauna species specified in Appendix III and in cases where, in accordance with Article 9, exceptions are applied to species specified in Appendix II, Contracting Parties shall prohibit the use of all indiscriminate means of capture and killing and the use of all means capable of causing local disappearance of, or serious disturbance to, populations of a species, and in particular, the means specified in Appendix IV. Article 91. Each Contracting Party may make exceptions from the provisions of Articles 4, 5, 6, 7 and from the prohibition of the use of the means mentioned in Article 8 provided that there is no other satisfactory solution and that the exception will not be detrimental to the survival of the population concerned:- for the protection of flora and fauna, - to prevent serious damage to crops, livestock, forests, fisheries, water and other forms of property, - in the interests of public health and safety, air safety or other overriding public interests, - for the purposes of research and education, of repopulation, of reintroduction and for the necessary breeding, - to permit, under strictly supervised conditions, on a selective basis and to a limited extent, the taking, keeping or other judicious exploitation of certain wild animals and plants in small numbers. 2. The Contracting Parties shall report every two years to the Standing Committee on the exceptions made under the preceding paragraph. These reports must specify:- the populations which are or have been subject to the exceptions and, when practical, the number of specimens involved, - the means authorized for the killing or capture, - the conditions of risk and the circumstances of time and place under which such exceptions were granted, - the authority empowered to declare that these conditions have been fulfilled, and to take decisions in respect of the means that may be used, their limits and the persons instructed to carry them out, - the controls involved. CHAPTER IV Special provisions for migratory speciesArticle 101. The Contracting Parties undertake, in addition to the measures specified in Articles 4, 6, 7 and 8 to coordinate their efforts for the protection of the migratory species specified in Appendices II and III whose range extends into their territories. 2. The Contracting Parties shall take measures to seek to ensure that the closed seasons and/or other procedures regulating the exploitation established under paragraph 3 (a) of Article 7 are adequate and appropriately disposed to meet the requirements of the migratory species specified in Appendix III. CHAPTER V Supplementary provisionsArticle 111. In carrying out the provisions of this Convention, the Contracting Parties undertake:(a) to cooperate whenever appropriate and in particular where this would enhance the effectiveness of measures taken under other Articles of this Convention; (b) to encourage and coordinate research related to the purposes
