What is a mesic area?
Wet “mesic” habitats — places where water meets land — comprise less than 2 percent of the entire landscape. Yet neither people nor wildlife can survive without them, as evidenced by the early homesteaders who followed scarce water when they settled the West.
What is a mesic savanna?
Areas dominated by widely spaced or scattered trees so that they canopy is open or not complete. These areas are seasonally saturated.
What is a wet mesic prairie?
A mix of sedges, grasses and wildflowers that will tolerate seasonal saturation, as well as drier conditions during summer and fall.
Why are mesic prairies threatened?
Mesic prairies are found on sites that have relatively good drainage but also has high moisture available most of the growing season. Mesic prairies are the most threatened prairie because most were converted for agricultural use.
What is a mesic woodland?
Rich woodlands often dominated by beech and sugar maple. They occur on well-drained but moisture retentive soils in flat areas, as well as, north or east facing slopes.
What are hydric plants?
Wetland plants, or hydrophytic “water loving” vegetation, are those plants which have adapted to growing in the low-oxygen (anaerobic) conditions associated with prolonged saturation or flooding.
What is a xeric site?
Glossary Term. Xeric (habitat) Low in moisture. Dry environmental conditions. Habitats or sites characterized by their limited water availability.
What are forbs plants?
Technically, forbs are flowering, nongrassy “herbaceous” plants, which means they produce seeds and have stems and leaves that die back at the end of each growing season (versus woody plants, whose stems remain year after year). Informally, forbs are what most forest preserve visitors call wildflowers.
What is a sedge meadow?
Sedge meadows are sedge-dominated wetland communities with wet prairie grass co-dominants on saturated soils. Sedge meadows are characterized by their dense groups of tussock-forming sedges, which often grade into shallowly flooded marsh edges. Frequent fire is prescribed to retain the open structure of a sedge meadow.
How many prairies are in Illinois?
Today, these three prairie types largely correspond to the corn/soybean area, the wheat belt, and the western rangelands, respectively. Illinois lies within an area called the “prairie peninsula,” an eastward extension of prairies that borders deciduous forests to the north, east, and south.
Are there prairies in Michigan?
Prairies are diverse, fire-dependent native grassland communities that were historically abundant in southern Lower Michigan, and occur infrequently in the northern Lower Peninsula and the far western counties in the Upper Peninsula. They are dominated by warm-season grasses, herbs, and flowers with no or few trees.
What is mesic dry?
Dry-Mesic Soils These soils are not dry or balanced, but slightly dry and are more moist compared to dry soils.
What is mesic prairie?
Also called tallgrass prairie, mesic prairie was common historically, but is extremely rare today. This grassland community occurs on rich, moist, well-drained sites, usually on level or gently rolling glacial topography. The dominant plant is big bluestem ( Andropogon gerardii ).
What is a mesic habitat in geography?
Mesic habitat. Mesic habitats transition to xeric shrublands in a non-linear fashion, which is evidence of a threshold. Mesic is one of a triad of terms used to describe the amount of water in a habitat. The others are xeric and hydric . Further examples of mesic habitats include all of the earth.
How do mesic habitats transition to xeric shrublands?
Mesic habitats transition to xeric shrublands in a non-linear fashion, which is evidence of a threshold. Mesic is one of a triad of terms used to describe the amount of water in a habitat.
What is being done to protect mesic habitats?
Mesic habitats are under stress from various human activities such as ranching, however many conservation efforts are underway. As of 2010, over 1,474 ranchers have agreed to partner with the Sage Grouse Initiative under the U.S. Department of Agriculture in order to protect over 5.6 million acres of mesic habitat.
