“…Residual ash found on the soil surface is typically enriched with P and cations that are normally retained onsite and available for subsequent assimilation by emerging vegetation (Woodmansee and Wallach, 1981b;Wright and Bailey, 1982;Debano and Klopatek, 1988;Riggs et al, 1996). Not only do these enhanced chemical conditions encourage plant growth, but the improved nutritional status of emerging herbaceous plants increases the forage value of vegetation consumed by herbivores (Pearson et al, 1972;Hobbs and Spowart, 1984;DeByle et al, 1989;Carreira and Niell, 1992). The only difference between ®re treatments was the generally higher levels of foliar Mg on plots burned during the dormant season than on those burned in the growing season.…”

“…Although investigations in Arizona by Pearson et al (1972), Campbell et al (1977, and in central Washington (Weaver 1951) have been made, Mueggler (1976) concluded that generalizations are difficult because each combination of climate, vegetation, and soil must be considered separately. Further, none of these investigations evaluated trends in productivity, vegetative composition, and nutrient content simultaneously.…”

Trends in productivity and mineral content of herbaceous vegetation in Ponderosa pine and montane grassland over a 4-year period are reported. Dry matter production on burned areas was 1.4, 1.3, 2.2 and 1.6 times that on unburned sites in the four successive years following the fire. Annual forbs and annual grasses contributed 56% of total dry matter the first year following fire. Perennial forbs contributed 40, 75, 75, and 77% of dry matter on the burned sites in successive years following the fire, compared with 66% on the unburned site. Herbage mineral concentrations did not change appreciably following fire, although low values for nitrogen and potassium were apparent in the first year.Responses of herbaceous understories in Ponderosa pine (Pinus ponderosa) communities to fire in the northern Rocky Mountains have not been extensively evaluated. Although investigations in Arizona by Pearson et al. (1972), Campbell et al. (1977, and in central Washington (Weaver 1951) have been made, Mueggler (1976) concluded that generalizations are difficult because each combination of climate, vegetation, and soil must be considered separately. Further, none of these investigations evaluated trends in productivity, vegetative composition, and nutrient content simultaneously.A lightning-caused fire in Ponderosa pine and adjacent montane grassland on August 10, 1973, in the Upper Selway River (White Cap Creek), Idaho, provided opportunities to assess understory responses. It burned for 43 days over an 1,100-ha area, when it was extinguished by rain (Mutch 1974). The area is a portion of a fire management zone in the Selway-Bitterroot Wilderness where fires are allowed to burn under most natural conditions.Objectives of this study were to follow changes in vegetative production, composition, and mineral content on the burned area and compare with adjacent unburned sites. Study AreaElevations on the burn ranged from 935-1,830 m, with all study plots on south-facing slopes at 1,000-1,300 m above sea level. Soils were derived from Idaho batholith parent material consisting of decomposed granite, gneiss, and rhyolite (Greenwood and Morrison 1967). Habeck (1972) characterized these soils as low in fertility, water holding capacity and of weak structure. Average annual precipitation was 76 cm with peaks occurring November-January and April-June (Finklin 1977 The fire occurred under extremely dry conditions, with relative humidity as low as 11%, maximum temperatures to 32° C, and winds gusting to 45 km/ hr. Ground cover on south-exposed slopes was sparse and unevenly distributed. Burned study sites showed evidence of burned stubble but no litter. The fire burned rapidly over these sites and left little ash. Adjacent unburned slopes of similar topographic characteristics were used for comparisons.Elk (Cervus elaphus) and deer (Odocoileus hemionus, 0. virginianus) used these areas as winter-spring range. McCulloch (1955) reported heavy utilization of browse by elk on adjacent shrub winter ranges in the early 1950's, and pr...

“…Some studies showed that herbaceous plants growing on burned area contain more crude protein [22 -25] , less crude fiber [22,23,26] . Thus, the food digestible rate is increased [27] Sciences (KZCX3-SW-343) and "Xi Bu Zhi Guang" Project of CAS and (200233104) and Mr. Wolfgang Frey (former editor of German Journal of Wildlife ) for financing this research.…”

In order to determine the natural diet and food habitat use of Tarim red deer (Cervus elaphus yarkandensis), a study was carried out in Qiemo, Xinjiang , China from October 2000 to June 2001. Direct observation combined with faecal analysis method was used to determine the natural diet of red deer. 15 different species of plant were identified as food items. Among them, 13 species of plants were identified in winter diet and 9 species in summer. Red deer consumed a wider range of species in winter because of their nutrient requirement as well as the shortage of food and the scarcity of high-quality forage in the study area. Phragmites communis, Glycyrrhiza inflata and populus diversifolia were frequently present in the deer's diet whenever in winter and summer. Among them, Phragmites communis was the most abundant plant in the area and was included in the deer's diet. Observation on food selection frequency of captive Tarim red deer showed that Populus diversifolia was the first preferred species. However, this food was limited in the study area. Five food habitat types were found in the study area according to plant association: (1) Phragmites communis-Tamarix ramosissima association, (2) Tamarix ramosissima-Halostachys caspica association, (3) Tamarix ramosissima-Phragmites communis association, (4) Populus diversifoliaPhragmites communis association, (5) Burned area. Among them, Phragmites communis-Tamarix ramosissima association (reed meadow and reed marsh) was preferred to other types within the study area whenever in summer and winter. Dense reed cover could reduce the chance of detection from predator and obstruct attack from predator. Furthermore, under the cover of the reed, Tarim red deer was protected from direct solar radiation during the hours of hot day in summer. The reed meadow and marsh was preferred, presumably because the red deer could minimize their movements while searching for food, water and cover.
