The document examines the long-term effects of altered hydrology from ditching and road impacts on plant community structure in peatlands in Alberta, Canada. Preliminary results showed increased tree productivity in a ditched fen, consistent with other studies. Results from road-impacted sites were more complex, with one site showing increased afforestation and species richness in treatment plots while another showed few differences. Surface peat was drier in treatment plots across sites. Future work will investigate effects of peatland type, structure, and nutrient loading on ecosystem responses to altered hydrology.
