“…In the intermediate forest stage, the net productivity of the stand increases markedly, biomass accumulates greatly, litter return decreases, and high amounts of soil nutrients are absorbed with low nutrient return to the soil, resulting in a decrease in the contents of soil carbon and nitrogen. In the mature forest, the soil carbon and nitrogen contents exhibited an increasing trend due to the decreased growth rate of the trees, the low tree density, limited litter return, and relatively low absorption and return of soil nutrients that are conducive to the accumulation of soil nutrients in forests [47,48].…”

With increasing age, plants will cause changes in soil physicochemical properties. The objective of this study was to investigate differences in the soil physicochemical properties in different-aged Masson pine forest plantations (i.e., 10, 20, 40, and 60 years old). Soil samples were collected in a pure Masson pine forest plantation in Southwest China. The soil determination indexes included organic carbon, nitrogen, phosphorus and potassium contents, water content, bulk density, and pH. The soil pH of a 20-year-old forest was significantly (p < 0.05) higher than that of a 10, 40, and 60-year-old forest. In addition, soil-available phosphorus in a 60-year-old forest was significantly (p < 0.05) higher than that in the other three age forest groups. With increasing forest age, available phosphorus increased, while available nitrogen decreased at 20 years old and then increased at 40 years old. There was a significant positive correlation (p < 0.05) between total nitrogen and available potassium; no significant correlation (p> 0.05) between total phosphorus and total potassium, organic carbon, bulk density, and pH; and a significant negative correlation (p < 0.05) between available phosphorus and the water content. The availability and utilization efficiency of soil nutrients in young forests were higher than those in old forests and the intermediate forest age was an important time point that affected the soil properties. To improve the availability of soil nutrients and ensure the sustainable utilization of soil resources, it is necessary to increase the input of nitrogen and especially phosphorus. More attention should be given to the phytochemometric response with respect to the age of plantations.

“…Studies on the regeneration of miombo in GNAP show that species composition and woody vegetation structure (density, tree height) differ between regenerating and mature miombo patches (Montfort et al, 2021). Unfortunately, we lack data on elephant diet in GNAP to evaluate the suitability of GNAP for elephants from a foraging perspective.…”

“…Annual average rainfall is around 800–1,000 mm. The landscape of GNAP consists of a miombo woodland (67%) with continuous 10–20 m high tree cover (Montfort et al, 2021; White, 1983) and low nutrient quality for both woody‐plant and grass leaves (Frost, 1996) (Figure 2). Within this forest matrix, 30% of the land cover is composed of edaphic grasslands that are often flooded during the rainy season (Chidumayo, 1997).…”

“…Within this forest matrix, 30% of the land cover is composed of edaphic grasslands that are often flooded during the rainy season (Chidumayo, 1997). Miombo woodland understory vegetation is scarce, it can be found along the few perennial rivers (3% riparian forests) and in post-cultivation regenerating woodland (0.3%) (Montfort et al, 2021). Around the park, vegetation is a mosaic of small fields (<1 ha each), patches of regenerating woodland and open wooded savannahs that have lost their capacity to regenerate miombo woodlands (Figure 2).…”

“…The slash and burn practices have generated patchworks of forest, cultivated clearings and regenerating woodland at different stages of regrowth along the buffer zone of GNAP (Montfort et al, 2021). In 2019, nearly half of deforested patches were no longer cultivated and were covered by dense regenerating miombo vegetation (F. Montfort pers.…”

The Miombo species Parinari curatellifolia has a bark with a cork-rich rhytidome that was studied here for the first time regarding extract yields and composition, using the complete rhytidome and also the separated cork fraction. The objective was to analyse their potential as sources of extracts with antioxidant activities aiming at increasing the species’ valorization and our knowledge on cork-rich barks.The content in total extractives was 6.1% and 8.4% in rhytidome and cork, respectively, with the lipophilic extracts soluble in dichloromethane corresponding to 23% and 38% of the total extracts, respectively. In cork, triterpenes and sterols were the main families of lipophilic components (58.9% and 20.8% of all compounds, respectively) while the rhytidome lipophilic extracts had a much higher content of long-chain lipids, including alkanoic acids and ɑ,ω-diacids (28.8% and 7.0%, respectively), with terpenes representing 27.7% and sterols 8.4% of all compounds. Aromatics were also present in significant amounts of 12.1%. Triterpenes included compounds known for various therapeutic properties, e.g. betulinic acid, corosolic acid, maslinic acid and ursolic acid, thereby explaining the use of P. curatellifolia in traditional medicine. Ethanol-water extracts contained phenolics, flavonoids, and tannins, and showed low (cork) or good (rhytidome) antioxidant properties. The outerbark of P. curatellifolia is therefore a potential source of bioactive compounds.
