10 Reading Guides & Assignments Book has a lot of important information that we will not be able to completely cover. We have prepared reading guides that take you through the important material in the book. There are exercises at the end of each guide to help you process the material. Periodic quizzes over the reading materials on or shortly after the dates listed on the reading guide. Quizzes also cover any lecture or lab material discussed by that date. Chapter 1 4 quiz will be Thursday, Sept 3, All information in the course is cumulative.

12 Today s Laboratory Doolittle Pothole/Prairie first of 3 native ecosystems Should be a nice day chance of scattered thunderstorms Bring rain gear in case Temperature - ~ 80 F Long pants and closed-toe shoes recommended There is prairie cord grass sharp edges Numerous ant mounds Also poison ivy mixed in the other vegetation

13 Doolittle Prairie Laboratory Tall thisle Cirsium altissimum Ox-eye daisy Heliopsis spp Marsh milkweed Asclepias spp

14 Ecosystems are a function of = f(clipsrot) Cli = climate P = parent material S = soil R = relief, topography O = organisms (plants, animals, microbes) T = time Consider the differences in each factor across the state of Iowa Soil Forming Factors = f(cliprot)

15 Terrain Characteristics fresh glacial till * no loess cover * bands of knob and kettle terrain * areas of level terrain * poor surface drainage * natural lakes, wetlands

16 Generally Level Terrain Where would the potholes have been? Where would the hilltops have been? Where would creeks/streams develop? Winnebago County, Rice Lake photo by Gary Hightshoe

17 Poorly developed drainage Over time these potholes would connect and create creeks/streams Spring Run State Wildlife Management Area, Dickinson County Photo by Douglas C. Harr

21 Doolittle Prairie/Wetland Laboratory Group Activity - Paired reading exercise Part of each group please read the prairie section (p 3-7) and the other part read the wetland section (p 7-10) of the lab. Make sure you understand the differences between the three kinds of prairies and the four kinds of wetlands. Once you have read your section discuss it with your other teammates. 1 hectare (ha) = 2.47 acres (ac) 1 meter (m) = 3.3 ft

23 Kinds of Wetlands Paulustrine Lacustrine Riverine Tidal

24 Kinds of Wetlands Type I Ephemeral Wet Prairie Short high water Drains/farmed Type II Temporary Sedge Meadows WT within inches of surface much of the year Doolittle Prairie, Story County Photo by Gary Hightshoe Type IV Semi-permanent Deep fresh marshes 6 in to 3 ft of water Type III Seasonal Wetland Usually at least 6 in of water, may dry out in late summer

25 Doolittle Prairie Soils Kossuth Ottosen Bode Association Parent materials Lacutrine sediments, local alluvium or glacial till. Depressional soils Okoboji (center), Harps may surround it. Kossuth soils generally poorly drained on broad upland flats Ottosen gently sloping somewhat poorly drained Bode more slope, well drained, convex knolls (not at Doolittle)

26 Lab Exercise 1. General introduction to site using Soil Survey Info 2. Transects across prairie Describe plant communities Identify major plant species Relate to microtopography Relate to soils 3. Compare prairie soil and plant community with adjacent crop field soil and community 4. We will devote about 0.5 hours to finishing the lab in class on Thursday.

27 Each Group will complete a transect through a prairie/pothole complex. You will evaluate conditions in 1-1 m 2 plot in the prairie before the wetland,1 plot in the center of the wetland & 1 plot in the prairie after the wetland.
