The Gus Engeling Wildlife Management Area (GEWMA) near Palestine, Texas represents a relatively intact southern example of thickening and evergreen encroachment in oak savannas. In this study, 18 images from the CHRIS/PROBA (Compact High-Resolution Imaging Spectrometer/Project for On-Board Autonomy) sensor were acquired between June 2009 and October 2010 and used to explore variation in canopy dynamics among deciduous and evergreen trees and shrubs, and savanna grassland in seasonal leaf-on and leaf-off conditions. Nadir CHRIS images from the 11 useable dates were processed to surface reflectance and a selection of vegetation indices (VIs) sensitive to pigments, photosynthetic efficiency, and canopy water content were calculated. An analysis of temporal VI phenology was undertaken using a fishnet polygon at 90 m resolution incorporating tree densities from a classified aerial photo and soil type polygons.

  • Bur Oak Savanna
    Bur Oak Savanna 1992 Bur oak savanna remnants exist in the southern half of WNT. Native herbaceous vegetation typical of savanna exists in the understory and will serve as a fuel base for future prescribed burns. 1993 Much interest has been generated in savannas as a topic. In February 1993, the first North American Oak Savanna Conference was held in Chicago, Illinois. Refuge Biologist Drobney was a participant in an effort to share information and to draft a Midwest Savanna Ecosystem Recovery Plan. During the same conference, interest was generated in WNT’s savannas that have mesic to wet-mesic characteristics. Most of the current information about savannas has been derived from sand savannas. Sand savannas have been more likely to survive because they are less suited to agriculture and therefore less a subject to the plow. In addition, invasive woody species often tend to develop more slowly in dry sandy areas resulting in a longer time period prior to canopy closure. In some areas on WNT, prairie cord grass and other moisture loving species occur in the oak understory on hillsides associated with seeps. In other areas, savannas occur in relatively low moist areas. WNT, therefore, is potentially an important study site that could yield a better understanding of a once common kind of Midwestern oak savanna that is poorly understood and largely obliterated. 1998 In 1998, we cleared approximately 3 acres of trees in natural community remnants including Thorn Valley Savanna, Coneflower Prairie, Buzzard Head, and Don’s II. 1999 Hundreds of orchids of three species including twayblade (Liparis liliifolia), showy orchis (Galearis spectabilis), and nodding ladies’ tresses (Spiranthes cernua) were manifest and blooming profusely in summer of 1999 in the Buzzard Head Prairie remnant.

  • An Ecological Investigation Into a Remnant Oak·Savana in Southern Minnesota
    AN ECOLOGICAL INVESTIGATION INTO A REMNANT OAK·SAVANA IN SOUTHERN MINNESOTA by Scott C. Laursen Submitted for Independent Research St. Olaf College Northfield, Minnesota May 1997 Abstract: A small forested plot in Northfield, MN was examined to determine if it is a remnant oak savanna and to gather baseline data to assess the area's present successional status. The canopy of the 90m X 90m test site was dominated by old growth Quercus macrocarpa (bur oaks). The plot was divided into periphery and interior according to the size of surrounding shade-tolerant saplings, and radiation levels in both areas were measured over three days. The height of each oak's lowest living lateral branch was recorded along with the number of dead branches below it. Spatial dispersion, coverage, and the map location of each old growth oak were also determined. A soil pit was dug in the remnant and a nearby late-successional forest plot. Nitrates, percent organic matter, and pH were compared between the remnant and the comparison plot. There were significant differences in radiation levels, lowest living lateral branches, and number of dead limbs below the lowest living branch between interior and periphery oaks. Results suggest that each shade-intolerant Quercus macrocarpa is being overtaken from its base up, as growing invasive species reduce its light. Dispersion tests revealed a slight tendency toward a contagious pattern in the oaks, especially in the southern corner of the plot. The oak coverage estimate was less than 70°/o and, therefore, within the classification range of an oak savanna ecosystem as defined by the state of Minnesota.

This type occurs in southern Lower Michigan, northwestern Ohio, northern Indiana, northeastern Illinois, southern Wisconsin, and southeastern to northwestern Minnesota. This savanna/woodland/prairie type historically occurred as an ecotone between mesic hardwood forest and tallgrass prairie. Biophysical Site Description Northern oak savanna occurs primarily on level to rolling topography of glacial outwash plains, coarse- textured end moraines, and steep ice-contact features (Chapman 1984, Albert 1995, Cohen 2001, Michigan Natural Features Inventory 2003, Cohen 2004, NatureServe 2004). Soils are well-drained, moderately- fertile sands, loamy sands, sandy loams, and loams with medium-acid to neutral pH (5.6 to 7.3) and low water retaining capacity (Chapman 1984, Michigan Natural Features Inventory 2003, NatureServe 2004).

  • Oak Savanna (Oak Opening and Oak Woodland)
    PROPERTY PLANNING COMMON ELEMENTS COMPONENTS OF MASTER PLANS HABITATS AND THEIR MANAGEMENT Oak Savanna (Oak Opening and Oak Woodland) Description “Savanna” is a term for communities that are intermediate between prairies and forests. In the Midwest, savanna generally refers to an ecosystem that historically was part of a mosaic of plant communities representing a continuum from prairie to forest; savannas were the communities in the middle of this continuum. The mosaic was maintained by frequent fires and possibly by large ungulates such as elk. Oaks were the dominant trees. After Euro-American settlement, oak savanna as an ecosystem was fragmented and almost completely lost due to clearing and plowing for agriculture, overgrazing, or invasion by shrubs and trees due to lack of fire, lack of grazing, or both. Intact oak savannas are now extremely rare and the community, along with tallgrass prairie, is the most threatened in the Midwest and one of the most threatened in the world. Because savannas are intermediate communities that can grade into both prairies and forests, there are no clear dividing lines between them and there is no clear-cut or widely accepted definition of what a savanna is. In Wisconsin, the more ‘open’ part of the savanna continuum is referred to as oak opening and the more ‘closed’ or wooded part is referred to as oak woodland. These are described below. Oak Opening This is an oak-dominated savanna having less than 50% tree canopy coverage and more than one tree per acre. Historically abundant on wet-mesic to dry sites, very few remnants exist today.
