and now they are trying the serial approach once again.
Indeed - and the registration of this new T List entry on 8/1/18 was preceded on 1/11/17 by Mali's government adding 2 of those previously separate T List entries - "L'Arche de Kamandjam" and "Le Kambalon" - to Mali's List of National Cultural Heritage. Presumably these 2 actions so close together are connected. This report however indicates that there is plenty to do to protect them - "Malgré leur inscription à cet inventaire, les deux sites font l'objet de diverses menaces, notamment l'urbanisation anarchique, la spéculation foncière, l'utilisation inappropriée des abords immédiats et l'érosion hydrique."
So, with all these problems to address, it doesn't look as if the new serial T List entry is likely to be put forward in the near future - but it would certainly seem to be being actively progressed -

I note also that a much earlier T List entry from 8/9/99 titled "Kamablon" is still present on Mali's T List. Presumably an example of "double counting"? See http://whc.unesco.org/en/tentativelists/1347/
Finally - I note that the 3rd site which has been removed from Mali's T List to become a part of the new serial entry - "Le site de Kurukan Fuga (2009)"
- is directly related to one of Mali's inscribed Intangible Heritage entries titled "The Manden Charter, proclaimed in Kurukan Fuga
" which was also inscribed in 2009. See - https://en.wikipedia.org/wiki/Kouroukan_Fouga
