“…There is, however, a growing body of literature on leadership behavior in various species, with potential applications to population management (Bailey et al 1998, McComb et al 2001, Rands et al 2003, Conradt and Roper 2005, Couzin et al http://www.ecologyandsociety.org/vol19/iss2/art7/ 2005, Dumont et al 2005. Some have argued that the expanding human infrastructure has and/or will potentially have a negative effect on caribou (Nelleman et al 2001).…”

ABSTRACT. We studied a case of failure in applying traditional ecological knowledge (TEK) in comanagement as the basis for formal hunting regulations. We based the study on the Porcupine Caribou (Rangifer tarandus) Herd "let the leaders pass" policy, established for the Dempster Highway of the Western Canadian Arctic, and identified conditions creating barriers in the successful application of TEK through comanagement. Stated as propositions, identified barriers include: (1) the context-specific nature of TEK limits its application in resource management regulations; (2) changes in traditional authority systems, hunting technology, and the social organization of harvesting caribou affect the effectiveness of TEK approaches in a contemporary social setting; (3) indigenous efforts toward self-government and political autonomy limit regional comanagement consensus in a heterogeneous cultural landscape; (4) the mismatch of agency enforcement of hunting regulations and TEK-based education is problematic. We analyzed the case through four historical phases of caribou management, complementing the study with a literature review of TEK and wildlife comanagement to explain why TEK integration of caribou leaders in regulatory resource management fell short of success. Identifying and understanding the social dynamics related to these barriers make apparent solutions for transforming the comanagement process.

“…In Ethiopia, about 62% of the total land mass is classified as arid and semi-arid and mainly used for livestock production based on grazing (Kassahun et al, 2008). Proper management of grazing animals is important to maintain sustainable range resource utilisation in such areas (Bailey et al, 1998).…”

Plant cuticular n-alkanes have been successfully used as markers to estimate diet composition and intake of grazing herbivores. However, additional markers may be required under grazing conditions in botanically diverse vegetation. This study was conducted to describe the n-alkane profiles and the carbon isotope enrichment of n-alkanes of common plant species from the Mid Rift Valley rangelands of Ethiopia, and evaluate their potential use as nutritional markers. A total of 23 plant species were collected and analysed for long-chain n-alkanes ranging from heptacosane to hexatriacontane (C 27 to C 36 ), as well as their carbon isotopic ratio ( 13 C/ 12 C). The analysis was conducted by gas chromatography/combustion isotope ratio mass spectrometry following saponification, extraction and purification. The isotopic composition of the n-alkanes is reported in the delta notation (d 13 C) relative to the Vienna Pee Dee Belemnite standard. The dominant n-alkanes in the species were C 31 (mean 6 s.d., 283 6 246 mg/ kg dry matter) and C 33 (149 6 98 mg/kg dry matter). The carbon isotopic enrichment of the n-alkanes ranged from 219.37% to 237.40%. Principal component analysis was used to examine interspecies differences based on n-alkane profiles and the carbon isotopic enrichments of individual n-alkanes. Large variability among the pasture species was observed. The first three principal components explained most of the interspecies variances. Comparison of the principal component scores using orthogonal procrustes rotation indicated that about 0.84 of the interspecies variances explained by the two types of data sets were independent of each other, suggesting that the use of a combination of the two markers can improve diet composition estimations. It was concluded that, while the n-alkane profile of the pasture species remains a useful marker for use in the study region, the d 13 C values of n-alkanes can provide additional information in discriminating diet components of grazing animals.

“…Interactions of livestock with the ecosystem imply the choice of grazing location through discrimination and selection among vegetation patterns (Adler et al 2001). Decisions on feeding areas may be affected by feed abundance and also other valued assets such as watering points, location of supplementary feed distribution including mineral blocks, refuge and shade (Bailey et al 1998). These variations of attractiveness of resources in space and time create a spatial mosaic pattern of animal distribution.…”

Overgrazing in the Montado? The need for monitoring grazing pressure at paddock scale

2015

View full text Add to dashboard Cite

Montados are presently facing the threat of either abandonment or intensification, and livestock overgrazing has been suspected of contributing to reduced natural regeneration and biodiversity. However, reliable data are to our knowledge, lacking. To avoid potential risks of overgrazing, an adaptive and efficient management is essential. In the present paper we review the main sources of complexity for grazing management linked with interactions among pasture, livestock and human decisions. We describe the overgrazing risk in montados and favour grazing pressure over stocking rate, as a key indicator for monitoring changes and support management decisions. We suggest the use of presently available imaging and communication technologies for assessing pasture dynamics and livestock spatial location. This simple and effective tools used for monitoring the grazing pressure, could provide an efficient day-to-day aid for farm managers' operational use and also for rangeland research through data collection and analysis.
