All macrophyte taxa were recorded on the transects (width 10 m) starting at the willows or forest by the side of the lake and reaching into the water.
To delineate the littoral zone, we first identified the maximum depth of macrophyte growth by conducting snorkel surveys in five to 30 sectors of each lake, depending upon lake size (at least one for every 15 ha up to a maximum of 30, sensu Jeppesen et al., 2000).
A study of aquatic plants associated with the 'wadi' ecosystems has resulted in several positive outcomes, including the setting up of a comprehensive database for the macrophyte species in the Al Hajar Mountain range.
In plants treated with Zn, macrophyte growth increased in (600 and 1200 [micro]g/L) treatments but decreased in (2400 and 600 [micro]g/L) concentrations.

The non-native macrophyte hydrilla, although causing problems in many waters, conveys the ecological and angling benefits of native macrophytes, but its aggressive growth leading to high-density stands of "topped out" (forming a dense surface mat of stems that shades out plant growth below) vegetation can create hypoxic (low-oxygen) conditions that diminish hydrilla's value as fish habitat.
It was the most appropriate living environment for submerged macrophytes. It explains why the submerged plants were just degraded but not disappearing from the macrophyte communities of Xiangyang site after the water level rose to a pretty high level.
