[T A Newsome; Brian M Wikeem; D C Sutherland; British Columbia. Ministry of Forests. Research Branch.] -- Assists forest managers in evaluation of sheep grazing as a vegetation management option and in implementation of sheep grazing projects.

Insheep producers requested grazing permits from the British Columbia Ministry of Forests in Mile House to graze clearcuts with high fireweed cover. The possibility of using sheep to reduce vegetation competition in conifer plantations became apparent and the first sheep grazing trial was initiated in   It is our position that there is an opportunity to increase the use of sheep grazing for vegetation control in some regions of the northern forests of British Columbia and Alberta, thus providing another viable option for forest managers.

Key words: sheep, grazing, vegetation management, plantation establishment, conifer release, northern forestCited by: 3. Some findings on sheep grazing preferences are: Sheep prefer new, succulent growth, whether it is the spring flush or regrowthafter a first graze. Vegetation degraded by frost or drought has reduced palatability.

Target vegetation should be less than 1m tall so that the sheep can grazethe entire plant. Sheep Grazing is a unique initiative in Chetwynd, British Columbia where sheep are used to manage the brush in the working forest.

Using sheep in certain areas of the forest helps to address values that are vital to local Indigenous peoples. “Competing vegetation can cause challenges for proper tree growth, so we use sheep in sensitive areas to eat through the vegetation.

In British Columbia, sheep vegetation management (SVM) is a relatively new technique; thus, limited data are available for examining its benefits on conifer growth. We collected field data from young mixed-conifer plantations of lodgepole pine (Pinus contorta) and hybrid spruce (Picea glauca × P.

1. The British uplands are internationally important for their unique plant and bird communities. They have considerable economic, nature conservation, landscape, aesthetic and tourism‐related value and as a result are under a variety of different pressures, most notably from sheep farming, shooting interests, commercial forestry and conservation interests.

vegetation management objective, sheep grazing within plantations requires careful planning, execution, and moni- toring to meet the desired outcome. Sheep were first used experimentally for vegetation management in the Cariboo region of British Columbia in Since then, trials have been undertaken in all regions of the province and have shown that sheep grazing is a successful means of managing vegetation on certain forest plantations under specific conditions.

Forest Grazing: Impacts and Management I. A Problem in Plantations: A. Competition between young seedlings and existing vegetation can reduce growth of young trees. Dense ground vegetation can improve habitat for voles, and other small rodents, which can damage trees.

Dense vegetation can increase risk of fire. In British Columbia, sheep grazing is used as a vegetation management tool in young forest plantations). Riparian Buffers and Integrated Riparian Management.

Riparian buffers are managed forest and shrubs belts in areas bordering lakes, streams, rivers, and wetlands. Sheep grazing was investigated as an alternative to traditional management of meadows in the Krkonoše Mts.

Until the second World War these meadows were mown in mid‐summer and grazed by cattle for the rest of the season. Subsequent abandonment of the meadows has resulted in decreasing species richness.

these somewhat unpromising statistics, they concluded that controlled grazing by sheep was a useful management tool since the sheep did well, and did not seriously interfere with fir seedling establishment.

Pettit (), in N.E. Oregon, grazed a burnt forest which had been reseeded with various conifers at trees/ha with 2 5 heifers/ha. Good. Livestock, pasture, and timber trees are intimately interrelated in silvopastures.

Most silvopasture research to date has focused on forage/animal/tree interactions, with less attention paid to animal/soil interactions in silvopastures. While a considerable body of work has been devoted to understanding the effects of livestock trampling on plants and soils in. Research and Information.

Targeted Grazing or Managed Herbivory is carefully controlled grazing of livestock to accomplish specific vegetation management objectives. This precise application of grazing can be honed into a powerful weed management tool.

Biologically sound tools are needed to manage the weedy exotic plants that are invading into and devastating.

Forestry Plantation Much of the emphasis for a planting project is placed at the beginning with seed selection, nursery development, and outplanting.

Unfortunately, the project manager often reduces his efforts after the seedlings are in the ground. Given the high risks during this period of establishment, such reduced efforts could prove disastrous to the stand.

Some effects of domestic sheep grazing on vegetation and soils were measured at four sites in the western Mojave Desert. Although sheep have grazed the Mojave Desert for the past 50– years, the effects of grazing on the desert ecosystem are largely unknown.

The results reflect only short-term effects of grazing, because fenced control areas were not available for study. or near potential natural vegetation and should be used as a benchmark area for judging range condition and the impact of Sheep Grazing on Fig. Fence line view contrastingforb dominonee in the reference area (right) with gross dominance in the sheep-groredpasrure 12e/t.

The suggested timetable applies to ewes with high productivity assuming that no concentrates are offered at pasture.

Non-native, Sitka spruce Picea sitchensis, the main plantation species in upland Britain, appears unpalatable to sheep and cattle. There are a few reports of chemical impoverishment of forest soils by grazing in unfertilized forests. There are reports of physical damage to forest soils (several papers reporting this refer to cattle).

Silvopastoral systems, consisting of the combined management of pastures, woody perennials and animals, are increasingly adopted throughout the world, especially in the tropics.

However, reports of problems to the trees caused by the animals grazing these areas are also increasing. Damages inflicted by cattle to adult trees may include branch breakage, trunk.

These sites were lightly grazed year round under collective sheep grazing for 30+ year (–) based on historical animal numbers. The stocking rate at each site was estimated at about sheep months (SM) ha −1 before but subsequently increased to an average of aboutand SM ha −1 at Sites I, II and III, respectively, by when.

Pastures are those lands that are primarily used for the production of adapted, domesticated forage plants for livestock. Other grazing lands include woodlands, native pastures, and croplands producing forages.

The major differences between rangelands and pastures are the kind of vegetation and level of management that each land area receives. Sheep grazing days in a paddock Below is a worked example estimating the number of sheep grazing days in a paddock. Table Estimation of the amount of pasture and sheep grazing days in a paddock.

Assumptions: early winter (1 May) when pasture growth is 10 kg DM/ha/day and maintenance feed required for the ewes is 1 kg DM/head/day. The timing, intensity of grazing, kind and class of animal (e.g., beef cattle compared to sheep), and utilization are important considerations in grazing management; RDM serves as an effective index for these factors.

Ungrazed plots within Morgan Territory and Sunol-Ohlone were located in areas where livestock grazing was removed at least GENERAL DISTRIBUTION: Coast Douglas-fir grows from west-central British Columbia southward to central California. In Oregon and Washington its range is continuous from the Cascades west to the Pacific Ocean.

In California, it is found in the Klamath and Coast ranges as far south as the Santa Cruz Mountains, and in the Sierra Nevada as far south as the Yosemite.

For this reason, it is not currently recommended for sheep pasture. When seeding new pasture it is best to seed a mixture of grasses and legumes. However, one should avoid putting too many species in the mix to avoid competition among the components and increase difficulty of grazing management when species do not mature at the same time.

Escalating controversy on clear-cutting, herbicides, burning, and grazing led to a research program with 40 studies, begun inthat compared most of the vegetation management techniques used.

In a number of systems, conservation efforts are increasingly aimed at managing land for livestock–wildlife coexistence.
