An ecological study of the vegetation of the Bear River Migratory Bird Refuge, Box Elder County, Utah

Creator:: Kaltwasser, Robert George
Abstract:: During the summers of 1971, 1972, and 1973, a general floristic ecological survey of the naturally-occurring vegetation of the Bear River Migratory Bird Refuge in Utah was carried out. Ten community types were identified and characterized. These included two aquatic communities, the Potamogeton pectinatus (Pope) and the Ruppia maritima/ Zannichellia...

Invasion by trees into a grassy bald on Marys Peak, Oregon Coast Range

Creator:: Magee, Teresa K.
Abstract:: Grassy balds are meadows that occur on or near the summits of montane peaks and ridges. The sites on which balds are located generally fall within the climatic tolerance ranges of associated tree species. This study evaluates the stability of a forest-meadow transition zone of such a bald on Marys...
