In a context of unbridled erosion of biodiversity, it is important to protect, and conserve protected areas by carrying out studies, in particular on the flora and vegetation of which they are composed. A study was carried out in the Dahliafleur Reserve in Côte d’Ivoire, with the overall aim of assessing the level of biodiversity conservation. The methods used in this study were surface and itinerant surveys. The results revealed that there are three types of plant formations in the Dahliafleu Partial Nature Reserve, in order of importance: secondary forests (76.38 ha), fallow land (59.53 ha) and bamboo groves (10.17 ha). The flora is rich in 224 species divided into 186 genera and 105 families, the most important of which are the Fabaceae, Apocynaceae, Euphorbiaceae and Rubiaceae. Most of its flora consists of species from the Guinean Congolese or forest zone. The reserve has 39 species with special status, which shows its importance and the interest of its protection against anthropic pressures. According to the Forest Stewardship Council (FSC), three (03) High Conservation Value (HCV) categories have been reached. These are HCV1, HCV2 and HCV4. The data obtained from the study highlights the biodiversity conservation value of the Dahliafleur reserve. Resilience strategies must therefore be adopted by the reserve manager, ranging from conservation to enhancement of this biodiversity.

A case study on wood-decaying macrofungi in the Southwestern slopes of Vasilyovska Mountain, Forebalkan, Bulgaria

This study was performed based on specimens of macrofungi collected on field trips to the region between 2007 and 2011. The aim of this study was to determinate the wood-decaying macrofungi of Vasilyovska mountain, to enrich the information about fungal diversity in the Forebalkan floristic region, and make contribution to Bulgarian mycota. The information upon species composition and distribution of wood-decaying macrofungi in the Vasilyovska mountain were published for the first time including the second records of Armillaria ostoyae, Pholiota lucifera and Xeromphalina cauticinalis in the country. A list of 110 species belonging to Pezizomycota and Agaricomycota has been compiled which 75 species were reported for the first time from Forebalkan. Four species includes in the Red List of fungi in Bulgaria: Fomitopsis rosea (Alb. & Schwein. : Fr.) P. Karst., Hericium coralloides (Scop. : Fr.) Pers., H. erinaceus (Bull. : Fr.) Pers., and Lenzites warnieri Durieu & Mont.

New global estimation of biodiversity benefits and ecosystem services finds flows valued at $1 trillion USD per year to poor communities.

...

But while the concept of ecosystem services has gained more and more supporters and visibility, it has also attracted a number of critics over the years. Notably, in 2006, Douglas McCauley published the critique, “Selling Out On Nature” in the journal Nature where he suggested that “we will make more progress in the long run by appealing to people's hearts rather than to their wallets. If we oversell the message that ecosystems are important because they provide services, we will have effectively sold out on nature”.  I definitely see his point but I do think we need to use both these approaches, depending on target group. We here at SDUpdate have previously argued that speaking to decision makers the best way to make a change is to combine awe, fascination and wonder for the natural world with "need" messages - providing economic reasons against biodiversity loss - and "action" messages that make specific requests of the policy makers.  One of the most well known proponents of the ecosystem services concept, Gretchen Daily from Stanford University, has this to say about the environmentalists who criticize valuation and why she does not fully agree with them:  “To them, it’s a slippery slope that risks giving in to the ‘dark side’ of economics with no ethics. A wetland with high flood control value might be protected, whereas one with only aesthetic and recreational appeal may not measure up against a shopping mall. I share these worries, but we need to work pragmatically and confront the current situation. Let’s face it, most major decisions are made on a cost-benefit basis, and natural capital is assigned zero value.”

The conservation value of an organism is positively correlated with the relative size of its eyes and the degree of fuzziness (feathers or fur) of its young.
