“…Fire and the Quantity of Forage-Intense fires in chaparral result in a flush of herbaceous plants and shrubs for 1 to 5 years (Biswell 1974;Christensen and Muller 1975;Klinger and others 1989;Taber and Dasmann 1958). In Gambel oak rangeland in Colorado, fire did not significantly change the biomass of forbs and shrubs 2, 5, and 10 years after fall mixedseverity fire, but grass biomass was greater on burned than unburned sites during postfire year 10 (Kufeld 1983).…”

_____________________________________Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals' ability to thrive in the altered, often simplified, structure of the postfire environment. The extent of fire effects on animal communities generally depends on the extent of change in habitat structure and species composition caused by fire. Stand-replacement fires usually cause greater changes in the faunal communities of forests than in those of grasslands. Within forests, standreplacement fires usually alter the animal community more dramatically than understory fires. Animal species are adapted to survive the pattern of fire frequency, season, size, severity, and uniformity that characterized their habitat in presettlement times. When fire frequency increases or decreases substantially or fire severity changes from presettlement patterns, habitat for many animal species declines.

“…Seeds, and other diaspores of woodland species that were stored in the litter or buried in the upper parts of the A horizons, were consumed by the fire in the birch wood. According to Parusel (2006), who studied postfire forests in the neighbouring Rudy Raciborskie where all the humus layer was burned, the presence of Calamagrostis epigejos, C. villosa, Carex nigra, Deschampsia caespitosa, Juncus conglomeratus, J. effusus, Molinia caerulea, Pteridium aquilinum and Rubus plicatus were of such an origin (typical sprouters sensu Biswell 1974 andKeeley 1981), whereas most species must have naturally colonised the herb layer of these forests afterwards.…”

“…The mortality risk to plants depends on the amount of heat that they receive (high temperature plus exposure time) and on their susceptibility to fire, which is related to the amount of sensitive, meristematic tissue and the level of their exposure to heat (Brown and Smith 2000). Those plants that are able to survive a fire on a site are called sprouters (sensu Biswell 1974 andKeeley 1981), whereas seeders are the species that are killed by the flames and high temperature and therefore have to colonise the post-fire site from neighbouring communities (Whelan 1995). Species from the first group recover via vegetative propagation, whereas the latter rely on sexual reproduction (Tsuyuzaki et al 2013).…”

The studies, which were conducted in southern Poland, focused on the recovery of the herb layer in 17-year-old post-fire silver birch and black alder forests. Although both types of stands, which are of the same age, developed spontaneously, the alder stands occupied damper sites (with thicker A horizons that survived the fire) than those in the birch forests. We surveyed the migration rates of 44 woodland species, primarily ancient woodland indicators, into both forests and the potential differences in these rates depending on their moisture regime and the community type represented by unburned forests, which were treated as the source of the woodland species pool. Additionally, the role of local depressions with high humidity that were covered by post-fire alder woods in the colonization process, as well as species survivorship and recolonisation, were estimated. Woodland species showed diverse migration paces among the sites; most of them migrated faster on more fertile sites with a higher humidity. Small patches of post-fire alder woods contributed to the recolonisation process since many woodland species in the herb layer survived the fire due to its high humidity, which inhibited the intensity of the forest fire. The recovery of woodland species in post-fire woods is the combined effect of regeneration, which relies on autochthonic propagules, and secondary succession, which is based on allochthonic propagules. Local depressions, which provide refuges for fire-sensitive, dispersal-limited species, contribute to their survivorship and thus to the successive recovery of herbaceous layers after a fire.
