In 2014, I have been in the National Park of Mbam and Djerem during a 3 months period, for the purpose of completing an internship. I had the amazing surprise to discover a protected area that I should qualify as "complete". Complete, because it is representative of the whole country in terms of landscape (forest, savannas, rivers, waterfalls, mountains, etc) and biodiversity. In fact, the national park, created in 2000 and with 416 512 ha area, is located in a transitional ecotone between forest and savanna. It attracts the attention of many researchers from various countries, interested in studying and understanding wildlife, such as primates, elephants for example, and vegetation as well. 

Clearing are open areas surrounded by a more or less dense forest. In the National park of Mbam and Djerem, they are usually appreciated by animals due to salt and water abundance compared to other sites of the forest. The presence of salt, reason why those clearings are called "salines", attract mammals, and specially ungulates and elephants finding a better quality fodder. A one month period training (August 2015) brougth me to carry out a descriptive study of these ecosystems. One approach has been the use of aerial photographs taken from helicopter with high resolution cameras available at WCS (Wildlife Conservation Society) headquarter around the study location; another has been the fixation of camera devices branded "Bushnell" on specific points with a nice view on the saline.

The Douala Edea Forest Reserve is located in the littoral region of Cameroon, in the west side, and is a reservoir of biodiversity developing within a wide and complex mangrove ecosystem. It is an emergency to preserve them and for that reason, the regeneration of community mangroves has been implemented in several villages within the Douala Edea Wildlife Reserve.

In 2017, a vegetation study of two National parks of the soudano-sahelian zone in Cameroon have been carried out through a one month period data collection, as part of activities engaged for respective management plans update, with the financial and technical support of the german cooperation. Bouba Ndjida (200 000 ha) and Benue (180 000 ha) are two protected areas classified as national parks with a great potential for ecotourism and research, but also threatened by several issues. In fact the main problems encountered, overgrazing, illegal wood harvesting and poaching have recently induced a fall of the wildlife and plant diversity, consequently affecting other sectors: economy, socio-cultural habits.
