The plant community along the shoreline of Lake Powell in Glen Canyon National Recreation Area is resilient and dynamic. It is surviving the fluctuations in water level that characterize such reservoirs, and native plants are becoming established. Although the diversity of animals associated with the exotic dominant, Tamarix ramosissima, is lower than that of native riparian species, a surprising number of species are associated with tamarisk in this harsh country.

The study of the riparian plant community along the shoreline of Lake Powell offers a unique opportunity to observe the development of a plant community from a very early stage. This annual report discusses some of the results of the initial phase of this study, which was designed to describe the structure of the plant community as it occurs today and to describe preliminary results of experiments begun to assess interactions between the exotic tamarisk and native riparian plant species.

Substrate Types

This research was initiated in November, 1988, to evaluate plant communities developing along the shoreline of Glen Canyon National Recreation Area in northern Arizona and southern Utah. One goal of this research is to determine the species composition of these communities and their distribution on representative substrate types throughout the recreation area. Secondly, the interactions of native and exotic plant species present in the recreation area will be evaluated experimentally, to determine the feasibility of establishing populations of native species in these plant communities which, currently, are largely comprised of the exotic riparian tree species tamarisk, Tamarix ramosissima.

The Impact

The near elimination of inland salt marshes in Central Europe occurred throughout the 19th and 20th centuries, and the currently remaining marshes exist in a degraded condition. This work examines the impact of groundwater level on the growth of plants from a seed bank obtained from a degraded salt marsh in proximity to still existing one through an ex-situ experiment. An experimental tank was set up with the sample seed bank experiencing differing levels of water level. There were 1233 specimens of 44 taxa grown from the seed bank, of which 5 species were abundant, and 10 species are considered as halophytes. Only Lotus tenuis from halophytes was more abundant, and only five species of halophytes were represented by more than three individuals. The water level has a significant impact on the number of species (based on linear regression analysis) as well as species distribution among different water level treatments (a non-metric multidimensional analysis (nMDS) followed by linear regression). The results show a strong negative relationship between the average water level and the number of species. The water level did not affect the species composition of halophytes, but differences in individual species abundances were found among the halophytes. The species Bupleurum tenuissimum, Crypsis schoenoides, Melilotus dentatus, and Plantago maritima grew on the drier and non-inundated soils. Tripolium pannonicum, Spergularia maritima, and Lotus tenuis grew on both wet and dry soils. Trifolium fragiferum and Bolboschoenus maritimus were found in places with water stagnant at the soil level. Pulicaria dysenterica grew in inundated soil.
