“…We know that native ungulates do not exist in a homogenous environment and their effects on vegetation are likely to vary across productivity gradients (Milchunas and Lauenroth 1993, Osem et al 2004, Pakeman 2004. Not only are ungulate effects likely to vary as a function of site productivity, but effects are likely to vary as a function of the ungulate species and ungulate density, which in turn may vary as a function of site productivity-with different or more ungulates in areas that are more productive (Bender et al 1997, Bauer 1990). However, little field data exist to determine whether these interdependent factors stabilize productivity across environmental gradients over the long term in shrubsteppe ecosystems.…”

Ungulate populations are managed in shrubsteppe ecosystems around the world, but relatively few long-term datasets are available that test the impacts of these grazers on shrubsteppe structure and function. This study evaluated 8 exclosures in 4 shrubsteppe communities to determine the effects of deer and elk over 35 or 55 years on (1) plant biomass and species composition, (2) soil nitrogen (N) mineralization and net nitrification rates, Olsen extractable phosphorus (P), and C:N ratios, and (3) arthropod diversity and abundance. The site with deer, the highest ungulate densities, and coldest climate (Sinlahekin Wildlife Area, WA) had greater vegetative biomass and cover inside the exclosures than outside. The sites with elk, moderate ungulate densities, and intermediate climatic conditions (Oak Creek and Wenas Wildlife Areas, WA) had no effects of exclosures on vegetative biomass or cover. The site with elk, the lowest ungulate densities, and driest climatic conditions (L.T. Murray Wildlife Area, WA) had greater shrub cover outside of the exclosures. Ungulates significantly increased net N mineralization and nitrification rates, providing a potential explanation for compensatory growth by grazed plants. Our data suggest that arthropod herbivory does not substitute for ungulate herbivory. To the contrary, arthropod diversity reflected ungulate-induced changes in plant biomass. In addition to effects on standing biomass, ungulates were associated with increased exotic plant species richness at all 4 sites. Our results suggest that there may be a balance between indirect positive and direct negative effects of herbivory on plants that varies with ungulate densities and site characteristics, and that arthropod herbivory does not functionally replace ungulate herbivory.

“…It has also been shown to enhance the growth rate of the remaining trees ( 29 ) and decrease their mortality rate ( 9 ). However, thinning also influences the understory organisms in forest ecosystems ( 6 , 42 , 63 ), thereby affecting the functions of the ecosystem ( 7 ).…”

Forest management activities, such as tree thinning, alter forest ecology, including key components of forest ecosystems, including fungal communities. In the present study, we investigate the effects of forest thinning intensity on the populations and structures of fungal soil communities in the Cryptomeria japonica forests of central Taiwan as well as the dynamics of soil fungi communities in these forests after a thinning disturbance. Although the populations of soil fungi significantly increased in the first 6 months after thinning, these increases had subsided by 9 months. This pulse was attributed to a transient increase in the populations of rapid colonizers. A multiple regression analysis positively correlated fungal populations with organic matter content and cellulase activity. Thinning initially provided large amounts of fresh leaves and roots as nutrient-rich substrates for soil fungi. Denaturing gradient gel electrophoresis (DGGE) profiles indicated that soil fungal communities significantly differed among plots with 0% (control), 25%, and 50% tree thinning in the first 21 months post-thinning, with no significant differences being observed after 21 months. The fungal communities of these forest soils also changed with the seasons, and an interactive relationship was detected between seasons and treatments. Seasonal variations in fungal communities were the most pronounced after 50% tree thinning. The results of the present study demonstrate that the soil fungi of Taiwanese C. japonica forests are very sensitive to thinning disturbances, but recover stability after a relatively short period of time.

“…Thinning of red pine in Michigan resulted in strong positive responses in ungulates (deer, elk), likely due to increased forage resources and hiding cover (Bender et al 1997). Other research has identified mixed results in response of small mammal species to thinning treatments (Bender et al 1997, Converse et al 2006. Wildlife responses to thinning may decline 4 to 5 years post-thinning as the canopy closes; thus, periodic thinning may be necessary if continued wildlife use is a management priority (Bender et al 1997).…”

Hazardous fuels management in mixed red pine and eastern white pine forest in the northern Lake States: A synthesis of knowledge

Fuels reduction decisions are made within a larger context of resource management characterized by multiple objectives including ecosystem restoration, wildlife management, commodity production (from timber to nontraditional forest products), and provision of recreation opportunities and amenity values. Implementation of fuels treatments is strongly influenced by their perceived influence on and compatibility with overarching management objectives. In some cases these objectives may be complementary while in others they may involve difficult tradeoffs. Such tradeoffs are only further complicated by institutional mandates, limited availability of information, and complex ownership patterns. Like natural resource managers across the United States, those in the northern Lake States must balance these competing demands as they seek to build their management programs. However, there is limited information available to support these management decisions in the mixed red (Pinus resinosa Ait.) and eastern white pine (P. strobus L.) forests of the northern Lake States. This report informs fuels management decisions in the northern Lake States by synthesizing existing knowledge from the fields of silviculture, forest ecology, wildlife ecology, forest economics, public acceptance, and decision science. We provide an overview of forests and fire regimes in the northern Lake States followed by a description of different fuels treatment techniques and their expected outcomes. We then include a discussion of comprehensive management principles to consider in developing fire and fuels management programs for the region.
