Soil sodium: Effect of Burning Patterns on Vegetation in the Fish Lake Burn Compartments
This study examines the effects of long-term prescribed burning treatments on vegetation structure and composition, productivity, and nutrient cycling in upland oak savanna and woodland vegetation. The basis for the study is an ongoing, experimental prescribed burning program begun in 1964 at Cedar Creek, and a similar program operating since 1962 on the adjacent Helen Allison Savanna property (owned by The Nature Conservancy). These prescribed burning programs are designed to subject upland oak communities (and some old fields) to different burn frequencies and patterns of burning, with the ultimate objectives of 1) restoring and maintaining the historically important savanna and open woodland vegetation, and 2) providing information about the effects of different burning patterns on vegetation structure and composition. This study addresses the latter of these two purposes and expands on it by also investigating possible influences of fire on resource availability (nutrients, water, and light) and net primary productivity. This study represents a continuation and expansion of experiments 015 and 094.

Plant aboveground biomass data: Effects of Various Nutrients and Water on Vegetation
This experiment was conducted within the fenced areas of fields A, B, C, and D. The purpose of this experiment was to determine the effect of various nutrients on vegetation. There were eight different nutrients and a control. The different nutrients were N, P, K, Ca, Mg, Na, H2O, and a combination of trace metals. There were 36 plots in each field, 4 replicates of the 9 treatment levels. The plots were 1 meter by 4 meters and were laid out in a 4 by 9 grid. The grid was divided into 4 quarters and treatments were assigned with a randomized block design.
Plant species percent cover data: Effect of Burning patterns on Vegetation in the Fish Lake Burn Compartments
The purpose of this experiment is to see what effect burning patterns have on vegetation. The survey was conducted in 12 different compartments. These are Cedar Creek burn compartments 1(101), 1A(201), 3(103), 4(104), 5(105), 7(107), 8(108), 9N(209), 9S(109), 10(110), 11(111) and 13(113). Four transects, 50 meters long and 25 meters apart, were established in each compartment. Six quadrats were marked along each transect at 0, 10, 20, 30, 40 and 50 meters. The quadrats are 1 meter by 0.5 meters. Sections were defined by dividing the transects in half and taking the area between transects. This creates six 25 meter by 25 meter sections.

Percent light penetration: Effect of Herbivores on Vegetation Treated with Different N Levels and the Effect of N Addition on Herbivore Populations.
The purpose of this experiment is to study the effect of NH4NO3 addition on vegetation and herbivore populations and the effects of various herbivores on vegetation treated with different nitrogen levels. This experiment is being conducted in fields A, B, and C and is nested within the macroplots of E004. There are 4 fence exclosures each designed to exclude a specific group of herbivores, a fence exclosure to exclude all 4 groups, a fence that should exclude no herbivores to measure fence effects, and a plot with no fence as a control. Exclosures are 2 by 4 meters and are located in macroplot subsections 3 and 8. Herbivore treatments are randomly placed in the grid. For a description of fertilizer added to E005, see file fertilization details. For a list of treatments, see the treatment layouts in file trmte05.

Tree data: Effects of Deer on Growth and Establishment of Woody Vegetation in Old Fields
The purpose of this experiment is to measure the effects of deer on the growth and establishment of woody vegetation in old fields. This experiment is located in fields A and B. There are 6 plots in each field. Each plot is 10 by 30 meters, with the long axis perpendicular to the field/woods margin. Plots within a field are spaced at least 5 meters apart. Approximately 5 meters of the 30 meters length extends into the woods, the remaining 25 meters extend out into the field. Each plot is divided into twelve, 5 by 5 meter sections. Six quadrats were placed within each exclosure in each 5 meters of length. Plots are located randomly within each of those blocks. To assign locations randomly a grid was set up from 0 - 4 along the length and 0 - 9 along the width of each plot and random numbers were drawn in pairs, one from each of the random distributions. The plots were marked with rebar. Three plots in each field are fenced with poultry netting, approximately 2 meters high, to exclude deer.

Vegetation Choice Survey: Twin Cities Household Ecosystem Project
We designed our methods to estimate carbon, nitrogen, and phosphorus fluxes through individual households, and to address two primary questions: 1. How are these fluxes distributed across households? 2. What biophysical and socioeconomic factors contribute to differences in these fluxes across households? Our hybrid approach combines: 1. A mailed survey 2. Energy provider records 3. On-the-ground landscape measurements 4. A computational tool (the Household Flux Calculator) 4. Parcel data (interpreted using GIS) The resulting dataset includes information on biophysical and socioeconomic variables that potentially influence household-level fluxes of elements. Using this method to study element fluxes at the household level allows us to explicitly link consumption choices and element fluxes.
Percent light penetration: Effect of N Addition on Vegetation with Mammalian Herbivory
The purpose of this experiment is to look at the effect of NH4NO3 addition in an unfenced area. The experiment is located in field E. There are 4 different treatments C, F, H, and I as defined in fertilization details in the "microplot" strategy. The plots are 4 by 4 meters and are laid out in an 8 by 8 grid with 1 meter aisles. From 1989-1994 plots with fertilizer treatment 1 were treated as complete controls, receiving no nutrients at all.
