TextSeries: Occasional Paper. 1 Publication details: Kentville, NS : 1988. Nova Scotia Department of Lands and Forests,Description: viii, 115 p. : ill. , maps ; 28 cmOnline resources: Abstract: A vast majority of freshwater wetlands in Nova Scotia are oligotrophic and do not support a diverse or abundant floral and faunal community.During the summer of 1984 a nutrient enrichment project was undertaken in an attempt to increase the food source for wetlands related wildlife and consequently increase wildlife usage on a 4.9 ha impoundment in East Bay, Jordan Lake, Nova Scotia. Nitrogen and phosphorus levels in the impoundment were elevated through the addition of Urea and Triple-Super-Phosphate fertilizers in 1985 through 1987. The effects of fertilization were evaluated through the monitoring of water chemistry,macrophyte growth and diversity, aquatic macroinvertebrate biomass and diversity and wetlands related wildlife use. During the three years of fertilization, aquatic invertebrate numbers increased by 516.8%, plant diversity increased from 0.379 sp/m to 0.692 sp/m and wildlife sightings increased from 4 to 8 sp/observation.
