Abstract: Anthropogenic pressures in the eastern zone of the Taï National Park have led to the fragmentation of plant formations. The forests in the eastern part of the park have suffered significant degradation of plant cover and a significant loss of biodiversity. Therefore, this study makes it possible to contribute to monitoring the dynamics of reconstitution of the plant cover based on the ecological characteristics and the distribution of epiphytes present in the Djapadji management sector. Floristic inventories were carried out. In the plots, all trees with a DBH ≥ 5 cm were counted and recorded for the study of the structure of plant formations, all species carrying an epiphyte were recorded and the epiphyte was identified. The analysis of the data presents a flora composed of 26 epiphytes distributed in 18 genera and 9 families, mainly present in mountain forests. The diversity of epiphytic plants is highest in mountain forests, followed by hydromorphic, secondary and gallery forests. Strict epiphytes and Hemiepiphytes are more present in the most preserved habitats, while accidental epiphytes are observed in reconstitution biotopes. The distribution of epiphytic plants allows us to affirm that the formerly anthropized forests of the Djapadji sector present a good dynamic of reconstitution.

Abstract: Saline and sodic water qualities used for irrigation could deteriorate soil physico-chemical properties based on type and amount of salts present in irrigation water and soil type being irrigated. Irrigation water with marginal quality could lead to the buildup of new soil characteristics that affect its fertility and productivity. In line with these issues, this review paper focused on reviewing the effect of irrigation water quality on selected soil physico-chemical properties in Ethiopia. Consequently, irrigation water quality of Errer River of Babile District, Ground water of Babile District, Tumuga and Gerjale irrigation sources, Adamitulu surface and ground water, Abaya Lake water, mixed water (Awash River to Beseka Lake River) and effect of these water sources qualities on selected soil physico-chemical properties were reviewed. The Errer River of Babile District, Tumuga and Gerjale irrigation water quality extent were within and below permissible value based on degree of restriction on use for irrigation and some selected soil physicochemical properties weren’t affected in observable extent due to quality of irrigation water. Certain irrigation water quality extent implied that Ground water of Babile District, Adamitulu Surface and Ground water, Abaya Lake water, mixed water (Awash River to Beseka Lake River) problem of suitability for irrigation and some selected soil physicochemical properties were affected due to extent of irrigation water quality were above threshold limit of irrigation water quality. The reviewed papers indicated that the soil quality was affected due to quality of irrigation water like its quality extent of salinity (EC), sodium adsorption ratio (SAR), residual sodium carbonate (RSC) and soluble sodium percentage (SSP) as it increased sodium, salt level and salinity in soil due to these parameters of irrigation water quality were above threshold limit, but calcium, magnesium and organic matter particulate content of irrigation water could improve soil fertility. Therefore, monitoring of irrigation water quality and checking of pre-planting and after harvesting soil physicochemical properties is very crucial to reveal and monitor the effect of irrigation water quality on soil physico-chemical properties.
