The Forest Preserves of Cook County have found prescribed fire to be economical. Forest inventory data. . Our study related terrain data to presence of northern hardwood forest type in the recovery areas of CNFS in the southern Appalachian Mountains of . The first contemporary conceptions of old-growth ecosystems in the twentieth century were rooted in the Romantic era philosophy of forests as primeval sanctuaries isolated from humanity, where one could seek "sublimity and uplift in the contemplation of nature, linking nature and the divine" ( Cox 1985, 156). Nowacki and Abrams assert that land use changes in the last century, particularly widespread fire suppression, are lead-ing to a "cooling" or "mesophication" of landscapes in east-ern North America. of Plant, Soil & Microbial Sciences .

The forest composition of the two plots differed when initial measurements were made in 1983 and 1984. . Restoring Perennial WarmSeason Grasses as a Means of Reversing Mesophication of Oak Woodlands in Northern . Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Char codes and their definitions assigned at the point of intersection for woody fuels (Page 14).

Nowacki and Abrams assert that land use changes in the last century, particularly widespread fire suppression, are lead-ing to a "cooling" or "mesophication" of landscapes in east-ern North America. 1. 2013; Alexander and Arthur 2014 ). Conifer species that typically encroach oak woodlands include Douglas-fir (Pseudotsuga menziesii), white fir (Abies concolor), incense-cedar (Calocedrus decurrens 2008. Background Mature oak ( Quercus spp.)

Past forest PMEs employed a variety of study designs related to treatment level, replication, plot and infrastructure characteristics, and measurement approaches. Foundation tree species are dominant and define ecosystems. AND M. D. ABRAMS. USDA Forest Service, Northern Research Station . At Fermilab, this is most apparent in the Big Woods, which was a mosaic of open woodland and savanna but is now a closed-canopy forest. Therefore, we reviewed the direction, the seral communities .

Discriminant analysis showed that the distribution of North American plant formations was more highly correlated with the water balance (actual evapotranspiration and deficit) than with the more traditional measures of climate (such as temperature and precipitation) used in .

The northern hardwood forest type is an important habitat component for the endangered Carolina northern flying squirrel (CNFS; Glaucomys sabrinus coloratus ) for den sites and corridor habitats between boreo-montane conifer patches foraging areas. Mastication treatment utilizes several different types of equipment to grind, chip, or break apart . 1620-1900) covering 28 states, 1.7 million trees, and 50% of the area of .

We examined canopy gaps on the 3,100 ha West Virginia University Research Forest (WVURF), a 70-80 year-old, second-growth, Appalachian hardwood forest near Morgantown, West Virginia. Wildfires are a serious threat for land managers and property owners, and over the last few decades this threat has expanded as a result of increased rural development. As young pioneer forests, the succession process is under way. Historically, the region . After dry mass determination, mineral mass mixed into the H-layer was .

Sustain. Nowacki and Abrams ( 2008) proposed that the process of mesophication over the last century in Northeastern U.S. forests involves establishment and overstory dominance of shade-tolerant species that generate dense shading, moist and cool microclimates at and near the soil surface, and a relatively inflammable fuel bed. Climate change can have profound impacts on biodiversity and the sustainability of many ecosystems. While oak and pine do . European arrival and forest clearance brought about an increase in fire and major declines in beech and hemlock, two quintessentially shade-tolerant, fire-prone species 15. Forest Service, Eastern Region, gnowacki@fs.fed.us) and M.D. The fire burns the forest to the ground 4. Max NielsenPincus . This process has been termed "mesophication" (Nowacki and Abrams 2008 ). ex D. Don) Endl.). Forests and grasslands have changed during the past 200 years in the eastern USA, and it is now possible to quantify loss and conversion of vegetation cover at regional scales.

This process has been termed mesophication and it has been linked to changes in fire regime.

Canopy gap sampling. 168 Global Ecology and Biogeography, 26, 166-176, 2016 John Wiley & Sons Ltd Forest growth resilience to drought Resilience growth indices quantified by calculating the mean length of ring-width series for the trees sampled in each site, in other words the mean For every dry year and . mesic - having or characterized by moderate or a well-balanced supply of moisture; "mesic habitats". It has been hypothesized that the expansion of maple and the resulting "forest mesophication" process will make the use of prescribed fire more difficult because litter beds dominated by maple foliage are less likely to carry a fire, . Forest plot observations from across the conterminous U.S. were extracted from the FIA database (FIADB version 6.1; O'Connell et al.

Common name: Davis's Shieldback Scientific name: Atlanticus davisi Status: Threatened Reason for designation: This flightless katydid is found only in six small areas of the sand barren and oak savannah habitats of the Norfolk Sand Plain in southwestern Ontario, where it occurs with other rare species of conservation concern such . We imagine the forest primeval, something timeless from our distant collective memory or perhaps nostalgia for what we imagine might once have been. NOWACKI, G.J. Landscape Ecology. Figure from Nowacki and Abrams: Fire regime change in the eastern United States. Special cameras collect remotely sensed images, which help researchers "sense" things about the Earth.

This saves a . The practice of classifying forest vegetation into communities (e.g., Clements 1916; Gleason 1926) or species assemblages (e.g., Fauth et al. The process of mesophication is usually associated with changes in fuelbed flammability (from light, flashy herbaceous fuels to dense, compact woody fuels), which further preclude fire and inhibit the success of fire-adapted species. Since the forests are distributed nationwide and are vulnerable to disturbances, the process may differ depending on the geography and/or site conditions. The NC Forest Service's primary purpose is to ensure adequate and quality forest resources for the state to meet its present and . The U.S. Department of Energy's Office of Scientific and Technical Information Because of the historical importance of oaks (Quercus) in east-central United States, it was unlikely that oak associates, such as pines (Pinus), hickories (Carya) and chestnut (Castanea), rose to this status.We used 46 historical tree studies or databases (ca. G. J. Nowacki, M. D. Abrams, The demise of fire and "Mesophication" of forests in the Eastern United .

trees are gradually being replaced by more shade-tolerant tree species across the eastern U.S., likely due to fire suppression and . Evaluation of the effectiveness of riparian zone restoration in the southern Appalachians by assessing soil microbial populations.

Landscape Ecology, 27(10):1495-1512. doi:10.1007%2Fs10980-012-9805-5. European settlement greatly altered fire regimes, often increasing fire occurrence (e.g., in northern hardwoods) or substantially decreasing it (e.g., in tallgrass prairies). Subalpine-High Montane Forest 2.87 2.58 0.84 A positive feedback cycle -- which we term ''mesophication'' -- ensued, whereby microenvironmental conditions (cool, damp, and shaded conditions; less flammable fuel beds) continually improve for shade-tolerant mesophytic species and deteriorate for shade-intolerant, fire-adapted species. 1996) provides ecologists and foresters a baseline expectation of what taxa and site conditions exist within a landscape.Classification often occurs at the stand- or site-level, where tree species diversity is almost always lower than at a landscape . A positive feedback cyclewhich we term "mesophication"ensued, whereby microenvironmental conditions (cool, damp, and shaded conditions; less flammable fuel beds) continually improve for shade-tolerant mesophytic species and deteriorate for shade-intolerant, fire-adapted species. Following Runkle (), we used a line-intersect method for sampling expanded canopy gaps.A canopy gap is defined as an opening in the forest canopy due to a death of a large branch, a single tree, or up to 10 trees, and where active recruitment of new individuals into the canopy is occurring (Runkle 1982a).An expanded canopy gap is the measurement to the base of the trunk of . Forested catchments are critical sources of freshwater used by society, but anthropogenic climate change can alter the amount of precipitation partitioned into streamflow and evapotranspiration, threatening their role as reliable fresh water sources. 2. Sarah E. Dalrymple; Axel Moehrenschlager .

Kentucky is leading to the decline of oaks in favor of more mesophytic species such as maplespart of the so-called mesophication of eastern . . 1620-1900) covering 28 states, 1.7 million trees, and 50% of the area of .

. 1786-1908) and current land cover and determined long-term ecosystem change to either land use or closed forests in eight states of the Great Lakes and Midwest. Various studies have investigated the impacts of climate change, but large-scale, trait-specific impacts are less understood.

These mesophytic trees slowly change the characteristics of the forest floor, making conditions more favorable for mesophytic regeneration and less favorable for oak regeneration over time (Kreye et al. 1. mesophytic - being or growing in or adapted to a moderately moist environment; "mesophytic habitats"; "mesophytic plants". The objectives of this study were: (a) to describe gap characteristics (size, age, fraction, regeneration and gap-makers) of the forest as a whole, and (b) to assess whether gap characteristics varied by slope .

In many publications, Abrams and Nowacki have argued that (1) the differences between the northern and southern forests of New England were attributable to the use of fire by Native Americans in the south, and (2) the cessation of burning by Native people initiated widespread changes in forest composition, characterized as "mesophication . .

We quantified historical (ca. BioScience 58(2): 123-138. Fire suppression results in the cessation of establishment of heliophytic, firedependent tree species. Our new definition, based on a warm season plateau in CD accumulation, provides additional information for diagnosing early-season freezing risks and later periods of potential vegetation moisture stress, both of which can have a strong influence on seasonal and interannual variabilities in vegetation phenology. However, the severity of CTL damage to residual trees in this forest type are unknown. By this, they mean that shade-tolerant,
