•
Virtual fence (VF) technologies can aid cattle producers in applying grazing management for land resource objectives.
•
Acute stress and animal welfare are important factors to consider when adopting VF on rangelands.
•
VF did not cause increased heart rate (HR) to mature, lactating beef cows when receiving audio or electric cues during a 30-minute period.
•
Increased HR was observed when cattle interacted with the electric cue boundary, but HR typically returned to levels observed during a control period within 30 seconds to 4 minutes.
•
Overall, VF caused minimal acute stress to the mature cows with calves and cattle learned to respond to audio cue warnings and avoid electric cues after being trained.

•
Most virtual fence (VF) devices use the Global Positioning System (GPS) to locate and track the position of livestock.
•
VF devices transmit GPS data across the internet to the VF software, and users can monitor the location and distribution of livestock across a pasture or grazing allotment in near real time.
•
Data from VF devices can be used to address resource management concerns as they occur rather than after, and managers can potentially use VF devices to alter livestock distribution if an undesirable grazing distribution occurs.
•
Users of VF devices should be aware of GPS errors and screen for erroneous data points when interpreting data from VF devices.
•
Large datasets generated by VF devices and lack of standardization present challenges for users of VF device data.

•
Riparian area protection, critical habitat protection, and rotational grazing are conservation practices with important ecosystem benefits, but they often require a large amount of physical fencing to implement.
•
Virtual fencing (VF) technology is effective for protecting small areas of critical habitat from cattle grazing in areas containing highly desirable forage.
•
VF technology is effective in excluding cattle from riparian areas; therefore, research is needed to understand how VF may benefit other ecosystems.
•
VF technology may be effective for implementing rotational grazing, and research is needed to understand the management of VF for rotational grazing across a wide range of grazing conditions.
•
Overall, VF technology has promise for protecting riparian areas and critical habitats from cattle grazing as well as for implementing rotational grazing.

Pastoralism, which is the chief mainstay for most of the population in the Somali region of the Horn of Africa, has witnessed sweeping changes. These changes are characterized by weakening resilience due to a combination of climate-induced challenges and anthropogenic factors, including overgrazing, deforestation, land-use changes, loss of soil fertility, and proliferation of invasive species.
•
This article provides a brief overview of rangeland management in Somalia starting from the colonial days until the collapse of the central government in 1991. The period that followed until 2016, which covers the years of self-declared independence of Somaliland up to the re-establishment of Aroori Grazing Reserve (AGR), was characterized by low investment in natural resources including agriculture, forestry, and rangelands and compounded by weak institutions due to the paucity of resources.
•
I outline the key takeaways from the 2016 restoration of AGR in Somaliland, including the area's value to pastoralists as a fodder reserve for livestock during hard times brought on by prolonged droughts. I also highlight emerging trends in community-led grazing management in the form of “village grazing lots” through joint land-use planning.
•
Grazing reserves serve as refuges and as tools to maintain indigenous grass biodiversity.

•
The extent of annual grass invasions in sagebrush ecosystems has required land managers to prioritize treatments in strategic locations to influence invasion outcomes. Maps of invasive annual grass cover show the extent and severity of the invasion, but they do not illustrate how invasive cover is changing over time.
•
The rate of change in invasive annual grass cover describes the trajectory of invasion. This information can be used to fine-tune priority locations and strategies for invasive species treatments.
•
We identified locations with positive, neutral, negative, and variable rates of change. Although rates of change have accelerated, there were many locations with a consistent neutral rate of change in cover. High positive rates of change frequently preceded high invasive annual grass cover, and locations that had low cover rarely had a history of high positive rates of change.
•
We identified potential management opportunities by combining rates of change in cover and percent cover data, illustrating both invasion severity and trajectory. We applied these potential opportunities to a map of the sagebrush biome using example thresholds. This map identifies locations that could be prioritized for different management goals and shows how those areas align with the Sagebrush Conservation Design management framework.

•
The traditional cultivation of wild melon varieties to feed and water animals during the dry season has proven to be economically sound and environmentally sustainable.
•
The practice is an example of mutual benefit and cooperation between settled agropastoral communities and mobile transhumant pastoralists.
•
Although the practice of cultivating local melon varieties to feed animals appears to be currently thriving, it might become endangered in the future because of the introduction of mechanization of crop farming as well as the increasing cultivation of hybrid melons that have brought new pests and diseases.

•
We created a mentoring and support group for women students, staff, and faculty in our academic unit.
•
The group met monthly to explore aspects of professional development, academic culture, workplace interactions, and work–life management.
•
Participants agreed involvement in the group was a positive experience.
•
We share summaries of the activities and topics the group addressed, and we encourage other agencies and institutions to consider forming women-focused mentoring programs.
