Long-Term Nitrogen Deposition: Effects on Succession Following Major Disturbances. Year 1990 Aboveground biomass data
The purpose of this experiment is to measure how initially disturbing an area and adding nitrogen over a long time will affect the number of species, the type of species present, the amount of annual growth, and the change from year to year in the growth of each species in a plant community which is...

| description |
The purpose of this experiment is to measure how initially disturbing an area and adding nitrogen over a long time will affect the number of species, the type of species present, the amount of annual growth, and the change from year to year in the growth of each species in a plant community which is also relieved of grazing by large and small mammals. This experiment is conducted within fields (A, B, and C) which were initially low in soil nutrients. The ground was disturbed by thoroughly disking the area prior to establishment of the experiment. There are 8 different levels of nitrogen addition with other nutrients added to ensure that nitrogen remains the limiting nutrient, and a control which receives no nutrients. Nitrogen fertilizer (NH4NO3) is applied twice per year, once in early May and once in late June. There are six replicates of each treatment per field. The treatments were randomly assigned to plots of size 4 by 4 meters. The plots are in 6 plot by 9 plot grids with 1 meter aisles between plots. The plot grids are enclosed by a fence to keep out mammalian herbivores. Gophers are trapped and removed as they appear. In the spring of 1992, subexperiments E097 and E098 were established. E097 is in fields A and C where randomly selected plots within each treatment no longer receive fertilizer. E098 is in field B where randomly selected plots within each treatment are burned. Note that the design of E002 is similar to E001 except E002 was thoroughly disked prior to establishment. |

The Cedar Creek Natural History Area is located in Anoka and Isanti counties, approximately 30 miles north of Saint Paul, MN. CCNHA lies at the boundary between prairie and forest. It is a mosaic of uplands dominated by oak savanna, prairie, hardwood forest, pine forests,and abandoned agricultural fields and of lowlands comprised of ash and cedar swamps, acid bogs, marshes, and sedge meadows. Large tracts of the pre-agricultural ecosystems of the region are preserved within its boundaries, as is a successional chronosequence of more than 80 old fields of known history. -93.22445 W -93.16289 E 45.44138 N 45.384865 S 1990 1990 |

Code of Ethics and Rules for Use of Cedar Creek LTER and Related DataAs a condition for access to data provided by researchers of the Cedar Creek LTER, I, the data user, agrees to abide by the following code of ethics.I agree to notify the Cedar Creek LTER scientists who gathered data if I would like to use those data in any publication. I acknowledge that these data were gathered by Cedar Creek scientists because they had already perceived the importance of these data for a variety of scientific and societal issues. I will provide them with formal recognition that, at their discretion, may include co-authorship or acknowledgements on publications. I realize that the researchers who gathered these data may be using them for scientific analyses, papers or publications that are currently planned or in preparation, and that such activities have precedence over any that I might wish to prepare. In this case, my preparation of any work may be delayed, at the option of the Cedar Creek researchers involved, until their work is completed. Because it may be possible to misinterpret a data set if it is taken out of context, I will seek the assistance and opinion of those Cedar Creek researchers involved in the design of a study and the collection of the data as I analyze the data. Moreover, I realize that this computer data set is not complete, and it may contain errors. The complete data set includes extensive written documentation, which should be referenced to reduce the chance of errors in data and errors of interpretation. |
