These should be brought into ex situ collections this group. as a matter of urgency. A full list of ebony taxa and their representation in ex situ collections is available in Annex 1. In this report we present the results of a survey of global ebony ex situ collections undertaken by Botanic Gardens Conservation Collections were also assessed on an individual level using International (BGCI) as part of our ongoing contributions to the additional data provided by gardens such as the sex and age Global Trees Campaign. This survey was commissioned by of their collections. This analysis showed that for most species Missouri Botanical Garden and forms part of the Global Ebony the sex and the age of the trees were not known.

Since its initiation, the GTC has expanded significantly, running projects that directly support the conservation of threatened tree species with partners in over 25 countries, leading training programmes to build capacity for tree conservation, and campaigning to scale up the use of threatened trees in planting schemes and conservation programmes. The GTC recognises that saving forests will not necessarily save the immense variety of tree species. Individual species play a myriad of economic, ecological, and cultural roles highly valued by today’s society. We depend on trees in our everyday lives – they provide us with food, timber and medicine. Furthermore, millions of species of plants and animals are intrinsically linked to tree species, depending on them for their survival. The GTC therefore

In recent years, there has been a growing inter- est in persimmon (Diospyros kaki L.f.) due to the presence of many different classes of phenolic compounds. However, the analysis of individual phenolic compounds is difficult due to matrix interferences. Methods: the aim of this research was the evaluation of individual phenolic compounds and antioxidant capacity of the pulp of two varieties of persimmon (Rojo Brillante and Triumph) by an improved extraction procedure together with a UPLC-Q-TOF-MS platform. Results: the phenolic compounds composition of persimmon was characterized by the presence of hydroxybenzoic and hy- droxycinnamic acids, hydroxybenzaldehydes, dihydrochalcones, tyrosols, flavanols, flavanones, and Citation: Esteban-Muñoz, A.; flavonols.

In order to observe flower visiting insects and floral morphology, and to determine the nectar producing capacity of persimmon flowers, field studies were conducted in 2018 and 2019. The anatomical studies were performed with light microscopy. Quantitative floral traits were analysed with two-sample t-test. The main flower visitors were honeybees (Apis mellifera L.) and bumblebees (Bombus sp.), which can act as pollinators, while searching for nectar. The studied persimmon varieties belong to the gynoecious type, the solitary pistillate flowers consisting of four- membered calyx and corolla, reduced androecium and a pistil with superior ovary and 3 to 5 stigmata. The size of the calyx was significantly different in different varieties, but corolla diameter did not differ within the same year of study. The diameter of both the calyx and corolla of the same variety was bigger in 2019 compared to 2018, due to favourable climatic conditions.

The study was carried out between April 2018 to February 2019. A total of 49 logged stumps were selected within the Akak forest spanning a period of 5 years and 20m x 20m transects were demarcated. All plants species <1cm and above were identified and recorded. Results revealed that a total of 5239 individuals from 71 families, 216 genera and 384species were identified in the study area. The maximum plants species was recorded in the year 2015 (376 species). The maximum number of species and regeneration potentials was found in the family Fabaceae, (99 species) and (31) respectively. Baphia nitida, Musanga cecropioides and Angylocalyx pynaertii were the most dominant plants specie in the years 2013, 2015 and 2017 respectively. The year 2017 depicts the highest Simpson diversity with value of (0.989) while the year 2015 show the highest Simpson dominance with value of (0.013).

According to the report of the Food and Agriculture Organization of the United Nation (FAO), approximately 13 million hectors of global forests have been lost annually due to forest land conversion to other land uses, forest fires and natural disasters, while reforestation and natural regeneration account for an increase of approx. 7.8 million hectors of forest cover. This means the net loss of global forest is estimated at 5.2 million hectors. Adverse impacts of forest conversion to farmland can be minimized as far as the land is properly used and managed in a sustainable manner. However, in some cases, problem soils are exposed and abandoned as degraded land. Deforestation by mining is a big issue these years. Problem soils such as strong acid soils and/or too much heavy metal soils appear at the ex-mining areas. In some cases it is too difficult to reforestate.
