“…Vegetation at the BREA contains elements of both northern and southern division oak-hickory forests, with somewhat greater abundance of northern species (Braun 1950;Rochow 1972;Nigh et al 1985). Historical land uses and settlement patterns in the region are not well known.…”

“…maple) and depletion of regeneration of current canopy dominants, particularly Quercus species, have been widely observed in the eastern United States (Schlesinger 1976;Miceli et al 1977;Lorimer 1984;Nigh et al 1985;Pallardy et al 1988;McClain et al 1993;Bell 1997;McCarthy et al 2001;Aldrich et al 2005;Ozier et al 2006). Withdrawal of fire as a frequent phenomenon in these forests is a widely accepted primary agent responsible for this shift, and nascent ascendance of shade tolerant species has been reported (Abrams 1992(Abrams , 2005.…”

Permanent vegetation plots established in 1968 at the Baskett Research and Education Area (BREA) were remeasured in 2004/2005 to assess trends in canopy composition, vegetation-environment relationships, and regeneration patterns. Quercus spp. [particularly Quercus alba (white oak)] remained dominant in BREA forests. However, NonmetricMultidimensional Scaling Ordination of a dataset composed of tree importance values from both samples indicated the two most common community types (Dry Ridge and Slope; Mesic Slope) were shifted away from Quercus spp. abundance toward greater importance of Acer saccharum (sugar maple) in ordination space. Plots in glade-like environments shifted toward greater Juniperus virginiana (eastern redcedar) importance. Environmental analysis indicated that soil properties (pH, organic matter, Ca, Mg, and K) and slope position were highly correlated with ordination axes. Saplings of Quercus spp. exhibited greatly reduced abundance in the most recent sample and the reduction in Quercus spp. density was highest in plots with greatest canopy cover. While Acer saccharum saplings were still quite abundant in BREA forests, smaller sapling size classes were becoming notably depleted, reflecting growth of a cohort of plants established before the 1968 sample toward and into tree-sized individuals. Seedlings surveys emphasized that A. saccharum seedlings have become very rare in BREA forests, while Quercus spp. seedling densities are higher, but likely below those needed for eventual adequate recruitment to the canopy. Although a number of mechanisms to explain apparent A. saccharum regeneration failure can be developed, herbivory, recent climate trends (warming late-winter conditions) and increased litter layer depth are the most plausible explanations for the observed scarcity of A. saccharum seedlings. Although increasing importance of A. saccharum in the canopy of BREA forests appears inevitable in coming decades, longer-term trends are unclear given the shortage of seedling regeneration.

“…Acer saccharwn (Aceraceae) is a shade tolerant tree (Logan, 1965;Forcier, 1973) capable of sustained population regeneration (Nigh et a!., 1985) which generally lives 200-300 years (Ledig & Korbobo, 1983). It is monoecious and self-compatible, although seed set from selfed flowers is poor (Gabriel, 1967) and selfing is restricted by incomplete dichogamy (Gabriel,1 968).…”

To examine the effects of forest fragmentation on within-population genetic structure of Acer saccha rum, the spatial distributions of allozyme variation in the first-year seedling cohorts of four forest patch populations (patches) were compared with those of four populations within continuous forest (controls). Forest patch populations exhibited less spatial mixing of genotypes than controls at the smallest scale examined (10-14.1 m), possibly as a result of reduced overlap of seed shadows in patches, which generally had lower densities of reproductive trees. Patch populations exhibited greater mixing of genotypes than controls at the largest scale examined (113.1-141.4 m), possibly as a result of the incorporation of immigrant pollen pools into mating events at forest patch edges. This may extend the spatial range of patch population breeding associations which might otherwise be truncated owing to limited forest patch area. Overall, results suggest that mating events are probably the primary determinant of spatial genetic structure within these cohorts in both forest patch and control populations of A. saccharum and that forest fragmentation has affected genetic structure by changing patterns of gene flow within, and possibly among, forest patch populations.

“…With cessation of fire, the prairies and savannas have since been invaded by woody species (Cottam 1949;Stewart 1951;Daubenmire 1968;Wells 1970;Whitford and Whitford 1971;Tans 1976;Whitford 1983;McCune and Cottam 1985). Other studies in the midwestern United States have shown waterways to form effective firebreaks and to separate prairie and xeric woodland from more mesic forest (Heinselman 1973;Grimm 1984;Nigh et al 1985;Whitney and Steiger 1985).…”

“…For example, the presettlement fire regime of the midwestern United States influenced the regional distribution of plant communities (Gleason 1922;Cottam 1949;Curtis 1959;Heinselman 1973;Vogl 1974;Davis 1977;Dorney 1980;Brown 1983, 1986;Whitford 1983;Grimm 1984;Nigh et al 1985). In many instances, fires eliminated woody vegetation, while maintaining prairie.…”

Effects of site, landscape features, and fire regime on vegetation patterns in presettlement southern Wisconsin

et al. 1991

The presettlement tree cover (1831 -33) of 3 townships in a southern Wisconsin landscape was analyzed using original survey records. Four forest types were identified: closed forest, open forest, savanna, and prairie. Comparisons of vegetation types and landscape pattern were made between the east and west sides of the Pecatonica River, which bisects the landscape and could have acted as a natural fire barrier. West of the river, presettlement tree species richness and diversity were lower and trees were smaller in diameter and less dense than to the east. The major vegetation types to the west were prairie (42~ of landscape) and savanna (40070), both fire-susceptible types. Prairie was more common on gentle slopes than on other landforms. To the east, the landscape was 70~ forested (closed plus open forest). Here, prairie was more frequent on steep dry sites. These vegetation differences, including the contrasting landscape placement of prairie, are attributed to distinct site characteristics and to disturbance (fire) regimes, with the west likely having more frequent fires. In terms of the four vegetation types, the east landscape was more homogeneous, being dominated by closed forest (50%). West of the Pecatonica River, the landscape was more heterogeneous because of the high proportion of both prairie and savanna; however, in terms of flammability of vegetation, the west was essentially homogeneous (82% prairie plus savanna).
