“…The efficacy and conservation benefits of targeted grazing can vary based on timing, duration, and intensity of grazing as well as the grazing species. High intensity spring grazing for short durations was most effective at reducing the abundance of the non-native annual grass medusahead (Taeniatherum caput-medusae L.), while native plant abundance increased for both sheep and cow grazing [15]. In a study on leafy spurge (Euphorbia esula L.), Rinella and Hileman [16] demonstrated that the overall effect of grazing on E. esula and native plants varied greatly depending on the timing, intensity, and frequency.…”

Integrated Management of Cheatgrass (Bromus tectorum) with Sheep Grazing and Herbicide

et al. 2019

Cheatgrass (Bromus tectorum L.) is one of the most problematic weeds in western United States rangelands and sagebrush steppe. It responds positively to different forms of disturbance, and its management has proven difficult. Herbicide or targeted grazing alone often fail to provide adequate long-term control. Integrating both may afford better control by providing multiple stressors to the weed. We assessed herbicide application, targeted sheep grazing and integrated herbicide and grazing on B. tectorum and the plant community in rangeland in southwestern Montana from 2015 until 2017. Herbicide treatments included spring-applied (May 2015 and 2016) glyphosate, fall-applied (October 2015) glyphosate, imazapic and rimsulfuron, and spring-applied glyphosate plus fall-applied imazapic. Targeted grazing, consisting of four sheep/0.01 ha for a day in 5 m × 20 m plots (all vegetation removed to the ground surface), occurred twice (May 2015 and 2016). While no treatments reduced B. tectorum biomass or seed production, grazing integrated with fall-applied imazapic or rimsulfuron reduced B. tectorum cover from approximately 26% to 14% in 2016 and from 33% to 16% in 2017, compared to ungrazed control plots, and by an even greater amount compared to these herbicides applied without grazing. By 2017, all treatments except spring-applied glyphosate increased total plant cover (excluding B. tectorum) by 8%–12% compared to the control plots, and forbs were generally responsible for this increase. Bromus tectorum management is difficult and our results point to a potential management paradox: Integrating grazing and fall-applied herbicide decreased B. tectorum cover but did not increase native grass cover, while some herbicides without grazing increased native grass cover, but failed to control B. tectorum. Additional research is necessary to determine grazing strategies that will complement herbicide control of B. tectorum while also stimulating native grass recovery, but this initial study demonstrates the potential of integrated management of B. tectorum compared to grazing or herbicide alone.

“…The use of targeted grazing is gaining traction among land managers and livestock producers as a sustainable approach to rangeland management. This approach allows for livestock production while supporting additional goals related to ecosystem health and wildlife habitat enhancement (James et al 2017; Davy and Rinella 2019; Porensky et al 2021; Rhodes et al 2021). Using focused and intentional decision making about where, when, and how to graze livestock to accomplish multiple goals across working landscapes can be expanded to include a wider variety of objectives, where cost-effective, or where nonmonetary motivations exist (e.g., enhancing pollinator habitat, accomplishing specific stewardship goals).…”

“…Targeted grazing is a cost-effective weed management alternative, especially on landscapes that are too steep, rocky, remote or large for conventional weed management (like mowing or chemical treatment). Grazing plans, livestock animal density, and grazing duration are important components that influence the ability of livestock animals to reduce the abundance of weeds (James et al, 2017). Herbicides are effective to control weeds, but expensive (Bailey et al, 2019).…”

To date, the idea of using livestock animals as biological tools to manage weeds, sequester carbon, and boost food security in oil palm plantations has not been seriously considered by industry stakeholders of major producing countries (e.g., Indonesia, Malaysia, Thailand, Colombia, and Nigeria). We revisit the integration of oil palm cultivation with livestock farming as a silvopastoral agroforestry practice in the wake of Sustainable Development Goals (SDGs). Oil palm-livestock integration has the potential to promote sustainable palm oil production because it can provide multiple environmental and socio-economic benefits, including carbon sequestration, restoring top soil, improving ecosystem biodiversity, reducing pesticide and fertilizer inputs, and boosting national food security. In contrast to monocultural outputs of most conventional plantations, an oil palm silvopastoral system is an ideal way to address the global food insecurity challenge as it produces bioenergy, vegetable oil/fat and animal-based protein sources (e.g., red meat). In addition, the potential of contract targeted grazing could be considered as a new type of business and income diversification for rural people. Oil palm-livestock integration is a strategy by the palm oil industry to achieve multiple SDGs. Out of the 17 SDGs, oil palm-livestock integration is likely to deliver nine SDGs. Palm oil certification bodies should recognize oil palm-livestock integration as a biological control method in weed management practices. We recommend that oil palm-livestock integration should be promoted to revitalize sustainable palm oil production and strategic biodiversity conservation policy. Policy makers should encourage major players in the palm oil industry to practice oil palm-livestock integration.
