Briefly describe the project goals and methodology
Evaluate the effects of long-term (>5 years) additions of nitrogen (N), phosphorus (P) and N+P on a Zizaniopsis milacea tidal freshwater marsh
Where will the project be located?
GCE site 7 - Hammersmith Creek
How will you provide GPS coordinates for study sites?
I will arrange with my research sponsor to collect and register GPS coordinates
What are the expected start and end dates of the project?
Start Date: 03/15/2004 End Date: (ongoing)
How many people will access the site and at what frequency?
Three to 4 people, three times a year (two times for 15 minutes to fertilize, one time for 3-4 hours to sample).
Please list keywords (as many as are appropriate) that describe your project:
What equipment will be deployed in the field?
One inch diameter pvc poles (2 meters in height) to demarcate plots. 16 plots with 4 poles each equals 64 poles total.
Will plants or animals be collected as part of this study?
Biomass is non-destructively samples in permanent plots. Five green leaves are clipped from each plot annually to measure leaf C, N and P.
What are the likely impacts of the project on the site?
Plots are relatively small (2 m by 2 m) so no long-term, large scale impacts expected. Expect to see enhanced aboveground biomass (and perhaps declining species richness) in N fertilized plots
Will the project design include boardwalks? If not, explain why not.
No. We make infrequent visits with few people so that the foot paths recover between visits.
How long will impacts persist after the research is concluded?
Small (2 meter by 2 meter) areas (N-treated plots) may exhibit high aboveground biomass for several years after nutrient additions cease.
