Western Land Managers Will Need All Available Tools For Adapting To Climate Change, Including Grazing: A Critique of Beschta et al

Journal Articles & Books
Dezembro, 2014

In a previous article, Beschta et al. (2013) argue that grazing by large ungulates (both native and domestic) should be eliminated or greatly reduced on western public lands to reduce potential climate change impacts. The authors were selective in their use of the scientific literature, and their publication is more of an opinion article than a synthesis. Their conclusions do not reflect the complexities associated with herbivore grazing. Interactions of climate change and grazing will depend on the specific situation.

Range expansion and comparative habitat use of insular, congeneric lagomorphs: invasive European hares Lepus europaeus and endemic Irish hares Lepus timidus hibernicus

Suécia

The European hare (Lepus europaeus) has declined throughout its native range but invaded numerous regions where it has negatively impacted native wildlife. In southern Sweden, it replaces the native mountain hare (L. timidus) through competition and hybridisation. We investigated temporal change in the invasive range of the European hare in Ireland, and compared its habitat use with the endemic Irish hare (L. timidus hibernicus). The range of the European hare was three times larger and its core range twice as large in 2012–2013 than in 2005.

Interacting effects of management and environmental variability at multiple scales on invasive species distributions

1. The distribution and abundance of invasive species can be driven by both environmental variables and land management decisions. However, understanding these relationships can be complicated by interactions between management actions and environmental variability, and differences in scale among these variables. The resulting 'context-dependence' of management actions may be well-appreciated by ecologists and land managers, but can frustrate attempts to apply general management principles. 2.

effects of a deferred grazing system on rangeland vegetation in a north-western, semi-arid region of Tanzania

Dezembro, 2013
Tanzania

The present study assessed the effects of deferred grazing management on rangeland condition using aboveground biomass, vegetation cover and species composition as indicators of range condition. The experiment was based on traditionally conserved exclosures (ngitili). Data were collected in Shinyanga rural and Meatu districts, Tanzania, from October to November 2011. Five grazing strategies were compared: old private ngitili , young private ngitili , old communal ngitili , young communal ngitili and continuously grazed land.

environmental narrative of Inland Northwest United States forests, 1800–2000

Journal Articles & Books
Dezembro, 2003
Estados Unidos

Fire was arguably the most important forest and rangeland disturbance process in the Inland Northwest United States for millennia. Prior to the Lewis and Clark expedition, fire regimes ranged from high severity with return intervals of one to five centuries, to low severity with fire-free periods lasting three decades or less. Indoamerican burning contributed to the fire ecology of grasslands and lower and mid-montane dry forests, especially where ponderosa pine was the dominant overstory species, but the extent of this contribution is difficult to quantify.

Managing woodlands for income maximisation in western Queensland, Australia: clearing for grazing versus timber production

Journal Articles & Books
Dezembro, 2003
Austrália

Queensland, Australia, has a proud pastoral history; however, the private and social benefits of continued woodland clearing for pasture development are unlikely to be as pronounced as they had been in the past. The environmental benefits of tree retention in arid regions of the State are now better appreciated and market opportunities have arisen for the unique timbers of western Queensland.

effect of development interventions on the use of indigenous range management strategies in the Borana Lowlands in Ethiopia

Journal Articles & Books
Dezembro, 2008
Etiópia

In the last three decades, the Borana rangelands of Southern Ethiopia have been deteriorating due to unsustainable utilization. This paper analyses the changes in indigenous range management among the Borana pastoralists and the role of development interventions.The fieldwork was carried out during 2000-2002, following a severe drought. Two locations, Dida Hara and Web, that once were part of a large grazing system with seasonally distinct herd movements, experienced differences in development interventions.

Farmers’ Perceptions and Satisfaction Levels on the Performance of Watershed Development Activities in the Morni Hill area of the Siwalik Himalayas in India

Journal Articles & Books
Dezembro, 2016
Índia

We describe the results of a survey of farmers’ perceptions of and satisfaction with the performance of watershed development activities on socioeconomic, agriculture and livestock, and environmental attributes. We administered a questionnaire to 120 farmers randomly interviewed in the Morni Hill area of the Siwalik Himalayas in India. Our results show that the farmers have considerable knowledge about the implementation of watershed development activities and their impact on the economy, agriculture and the environment.

Land-use and land-cover effects on regional biodiversity distribution in a subtropical dry forest: a hierarchical integrative multi-taxa study

Journal Articles & Books
Dezembro, 2014

Latin American subtropical dry ecosystems have experienced significant human impact for more than a century, mainly in the form of extensive livestock grazing, forest products extraction, and agriculture expansion. We assessed the regional-scale effect of land use and land cover (LULC) on patterns of richness distribution of trees, birds, amphibians, and mammals in the Northern Argentine Dry Chaco (NADC) over c. 19 million hectares. Using species distribution models in a hierarchical framework, we modeled the distributions of 138 species.

Long-term Impacts of Contrasting Management of Large Ungulates in the Arctic Tundra-Forest Ecotone: Ecosystem Structure and Climate Feedback

The arctic forest-tundra ecotone (FTE) represents a major transition zone between contrasting ecosystems, which can be strongly affected by climatic and biotic factors. Expected northward expansion and encroachment on arctic tundra in response to climate warming may be counteracted by natural and anthropogenic processes such as defoliating insect outbreaks and grazing/browsing regimes.
