“…Furthermore, regardless of its importance, dendrochronology must be used in conjunction with other tools, such as historical records (e.g., king lists), archaeological interpretations, C 14 dating, Sothic cycles, and synchronisms with other cultures, on which the problematic chronologies currently in use are based. Only by combining dendrochronology with other types of research can we fully ful l dendrochronology's potential for Egypt and nearby regions, and so provide speci c dates for other historians to discuss (Creasman, 2014;Kuniholm, 2014). Trunk girth (circumference) up to 330-340 cm of an older tree of Acacia tortilis subsp.…”

BackgroundTwenty-ve increment cores and tree discs were sampled for 4 trees species in Wadi Allaqi, an extremely arid region in South-East Egypt. All the studied species form distinct tree-ring boundaries. Of those, 19 samples for Acacia tortilis subsp. raddiana (Savi) Brenan, 2 for each of Balanites aegyptiaca (L.) Delile, Acacia ehrenbergiana Hayne, and Tamarix nilotica (Ehrenb.) Bunge. So, the main aim of the current study is to achieve a longer temporal perspective on growth and longevity, marginal parenchyma wood samples. ResultsThe growth ring boundaries of the acacias are differentiated by thin parenchyma bands, which run around the entire stem disc. Samples of Acacia tortilis subsp. raddiana were located in the up-, down-and mid-stream parts of this Wadi; and classi ed, based on the mean distance between the bands of marginal parenchyma, into 6 size classes. Longevity based on the marginal parenchyma bands indicated that Acacia tortilis subsp. raddiana grew slowly and some of its studied individuals re ected 2 age scenarios in the downstream part, while the measurement interval an established date of around 1884 or 1886 is suggested. Both scenarios grew fast over a long period of time, and so the chie y recent growth dated back to 1885. Approximate dates for the midstream part dated back to 1648, while the overall growth for the upstream part dated back to 1482. Samples of Balanites aegyptiaca may be established between 1608 and 1715, while those of Acacia ehrenbergiana may be established between 1945 and 1975. Tamarix nilotica swiftly established itself, and a new ecosystem replaced the severe arid habitat after the water level in Wadi Allaqi dropped in the 1980s. ConclusionTwo scenarios of age are probably true for the downstream part, implying a date of establishment between 1884-1886. Balanites aegyptiaca was thought to have been established around 1715 or 1608, whereas Acacia ehrenbergiana was thought to have been established around 1975 or 1945. It was also discovered that the outdated scenario for Balanites aegyptiaca and Acacia ehrenbergiana is more in line with asymptotic value and current growth, indicating larger possibility for future expansion.

Twenty-five increment cores and tree discs were sampled for four common trees in Wadi Allaqi, an extremely arid region in South-East Egypt (19 for Acacia tortilis subsp. raddiana (Savi) Brenan and 2 for each of Balanites aegyptiaca (L.) Delile, Acacia ehrenbergiana Hayne, and Tamarix nilotica (Ehrenb.) Bunge). The main aim of the current study is to achieve a longer temporal perspective on growth, longevity, and marginal parenchyma of the wood samples. The growth ring boundaries of the acacias are differentiated by thin parenchyma bands, which run around the entire stem discs. Samples of Acacia tortilis subsp. raddiana were located along this Wadi from its upstream to downstream parts; based on the mean distance between the bands of marginal parenchyma, longevity, based on the marginal parenchyma bands, indicated that Acacia tortilis subsp. raddiana grew slowly and some of its studied individuals reflected 2 age scenarios in the downstream part, while the measurement interval reflected an established date of around 1884 or 1886. Both scenarios grew fast over a long period of time, and so the chiefly recent growth was dated back to 1885. Approximate dates for the midstream part dated back to 1648, while the overall growth for the upstream part dated back to 1482. Samples of Balanites aegyptiaca may be established between 1608 and 1715, while those of Acacia ehrenbergiana may be established between 1945 and 1975. Tamarix nilotica swiftly established itself, and a new ecosystem replaced the severe arid habitat after the dropping of the water level in 1980s.Two scenarios of age are probably true for the downstream part, implying a date of establishment between 1884 and 1886. It was also discovered that the outdated scenario for B. aegyptiaca and A. ehrenbergiana is more in line with asymptotic value and current growth, indicating larger possibility for future expansion.
