Two recent influential documents mapped the current state of forest resources, and how it has changed over time. The second report is the FAO State of World Forest Resources report, that was launched during the just past World Forestry conference in Durban. This loss would have been greater was it not for the 110 million ha of forest plantations that were planted in the same time. Both natural and planted forests are under severe pressure from emerging pests and pathogens, either invasive or adapting from surrounding hosts. A FABIan, Prof. Consider signing up to either receive news or to write for The Conversation on their website.
Prof. The conference was held in Berlin, Germany from the 24th – 27th of August.

The youth are the future of the forestry industry. Leading the cause is the International Forestry Student’s Association (IFSA) that hosted a workshop on Forestry education in Africa at the WFC2015. South Africa will host the IFSA International Forestry Students Symposium (IFSS) in 2017 so it was apt that such a large group of students, especially those from across Africa were in attendance. IFSA President, May Anne Then, welcomed everyone saying that she was excited to learn more about African students and researchers’ experiences in Africa and to further the cause of forestry education for the youth. Addressing the large group of students at the opening of the IFSA pre-side event workshop, IUFRO President and FABI Director, Prof. Prof. Again addressing the students at the wrap-up session of the workshop, Prof.
As with many inter-disciplinary and wide-encompassing congresses like the 14th World Forestry Congress, there were many break-away sessions to home in on subject-specific forestry crises. Moderated by Dr Crous, the panelists of this session were left to freely comment on the topic: Is one tree worth the forest? The panelists consisted of the following people, and it was a privilege to have them join this most important discussion: Prof. Dr Brett Hurley (Forest Entomologist, FABI) Dr Clement Chilima (Director of Forestry, Government of Malawi) Roger Coppock (Head of Analysts, Forestry Commission, UK) Rory Mack (Department of Agriculture, Fisheries and Forestry: KwaZulu-Natal Division) Philip Ivey (South African National Biodiversity Institute, Cape Town) Joey Hulbert (PhD candidate, Forest Pathology, FABI) This topic was chosen to help us re-assess how to deal with the massive increase in forest invasive pests due to the import and export of live plants. Some key discussion points raised were that there needs to be more investment in human infrastructure (forest researchers) and physical infrastructure (quarantine facilities) to ensure that developing nations can also more rapidly and accurately detect new invasions. The dialogue session was a success, with the only draw-back being the 90 minute allotted time we were given to have this session – many things were left unsaid.
International Union of Forest Research Organisations (IUFRO) President Prof. More than 60 students from across the world including numerous African delegates from the Cameroon, Kenya, Morocco, Namibia, Nigeria and South Africa met in Durban to discuss the current state of forestry education in Africa. IUFRO sponsored 10 African forestry students’ attendance at the WFC 2015 as part of Prof. In his opening address Prof. He also encouraged them to use their time well to communicate their experiences from this workshop and, later, their professional work worldwide through writing editorials and thereby increase awareness about forestry.
