Cultural variation in river quality and macrophyte response. 1995. Acta Botanica Gallica, 142, 3458.
Rivers, and their vegetation, integrate the effect of all the environmental impacts acting on them, impacts both nature (e.g. rock type) and human (e.g. pollution, recreation). Human impacts vary in both their pressure, and in how that pressure is handled. Different peoples treat their rivers differently. This cultural variation means a habitat of, say, a limestone stream can be placed as being English, French or German by these subtler differences exerted by different peoples. Such cultural differences are easily overlooked, as the practices of each people are, for its inhabitants, both the right and the only way. Therefore, other ways do not exist, and ecological differences in other countries can easily be considered mis-observations.
Key Words: river, quality, macrophytic vegetation, cultural variation.
