Interesting Facts
Most of British Columbia's ranchers depend on crown range.
Crown range is typically used from May to October in the
southern portion of the province and June to September in the
northern portion of the province with private lands supplying
the forage requirements for the remainder of the year.
What is range?
Range is any land supporting vegetation that can be consumed
by both domestic livestock and wildlife and is managed as a
natural ecosystem. Rangelands are either owned privately or by
the Crown and are managed to supply forage for both livestock
and wildlife.
Where are rangelands in BC?
Rangelands occur throughout most of British Columbia and
are limited only by the rancher's imagination. Examples of
rangeland include community pastures, grasslands, forestlands
(logged and unlogged), shrublands, subalpine, alpine,
parkland, and riparian areas (wetlands and riverine). The map
indicates where range is currently being utilized.
How much forage on range is produced annually?
The amount of forage produced annually on range is very
difficult to predict and highly dependent on climate, soil,
elevation, latitude, and topographic conditions. Currently
crown range produces about 900,000 Animal Unit Months per
year. An Animal Unit Month is defined as the amount of forage
that is required for one month by an average cow aged 6 months
or older.
How is the forage on range produced?
Forage on range is generally produced by letting nature take
its course. Plants occurring on range use all the sun, water,
minerals, etc. available to them and produce forage that is
harvested by a rancher's livestock and local wildlife.
How is range used?
Range plants are grazed by livestock and wildlife, and regrow,
much like your law regrows after cutting. Under proper
management, it is often very difficult to determine if range
has been used. Generally, the only way to tell if use has
occurred is if livestock are present or if they have recently
moved.
What happens when forage leaves the range?
A small percentage of forage is harvested by both livestock
and wildlife allowing them to grow, raise their young, and
maintain their body condition.
What challenges do range manager's face?
Range is constantly being damaged by careless activities.
Plants are typically injured or killed by severe trampling,
overuse by both wildlife and livestock, and unauthorized use
by all-terrain vehicles, pedal bikes, and 4 x 4's. This
resulting damage severely limits the range from performing
important ecological functions such as holding the soil and
water in place. Human disturbance also provides an ideal site
for weed invasion. Numerous weeds including Toadflax, Leafy
Spurge, Knapweed, Houndstongue, Orange-flowered Hawkweed, and
Canada Thistle are all a serious menace to the health of BC
rangelands. Proper management applied with sound economics
protects our range resources. Visitors must always leave gates
as they are found and respect fences, as both are an important
part of range management.
