| Abstract | ||
| The wide spread of plants in the archeological areas led to many types deformation such as the increasing content of water in walls, the defects in the the falling of mortar. conveying of salts to the monumental buildings from soil serection of roots to the foundations of building and the deforming of the monument environment and other forms of damage. So it was necessary to pay visits to different archeological areas from north to south of Egypt and collecting samples from those plants and the soil they grow into limit the species of those plants, the family they are belonged to and the suitable soil for their growing. This will aim at techniques of its damage to the monumental buildings. The findings were that more than sixty types of plants belong to different families found in the archeological areas Some of them do not grow except in the salty soil like Arthrocnemum macrostachyum from the Fam. Chenopodiaceae. Juncus acutus, from Juncaceae family and imperata clyndrica from Poaceae family. Where as some plants grow in salty soil and non salty soil like Launeae residifolia, from Asteraceae family and Polygonum equisetiforme from Polygonaceae family And it was found that there are some plants which are to absorb salt from soil and secrete them on the leaves surface like Tamarix niiotica from Taman‘caceae family Or restoring them inside the leaves or inside the body the plants and when its satisfaction they dry and fall like Zygophyllum album from Zygophyilaceae family. Consequently wind in the first and in the second case are to transport what they contain of salts to the walls. Also it was found that the growing of some climbing plants which climb monumental buildings like lpomeae stoionifera from Convolvulaceae family Led to the increasing amount of water in these buildings and dissolving the linking substance for stones and dissolving what they contain salts and their results of damage forms. Again it was found that there are some plants like Convolvus arvensis from Convolvulaceae family are grown in the areas of mortar which lead to its separation and its falling because of their absorbing of water pressures resulting their growing. Also it was found that the increasing of plants in resulted in defects in the soil as a result of absorbing what it contains of water, there fore they affect the buildings they grow on. The secretion of roots leads to organic compounds and non organic to many different forms of damages. In addition to its existence in the archeological areas leads to deforming the environment of monument. It was noticed that more plants are f0und in the monumental areas lower Egypt than in upper Egypt. This may be for two reasons, first because monumental buildings are found in agricultural soil in lower Egypt which contain factors of agriculture, second because the dislocating of most archeological areas lower Egypt on the tourist map of Egypt which resulted of the unconcern for these areas that helped in growing a lot of plants there. Hence it's a must to clean these archeological areas from those plants by using the suitable methods whether they preservative, mechanical or chemical. This will depend on the sort of the plants found and repeat this for many coming seasons until we get sure of getting rid of the seeds of those plants in the soil completely. This necessity because there is a bank of seeds in the soil which contain those plants which gives renewal of covering for natural plants for many years, in addition to what they are distinguished for many qualities that help them to continue and spread. | ||
