Unique Vegetation
|
Waterton Lakes National Parks has a huge
variety of plants. Waterton Park is a biosphere
reserve, meaning it has been set aside by
UNESCO (United Nations Educational,
Scientific, and Cultural Organization) as a
region which is unique in its ecology.
Of the 45 vegetation types identified in
Waterton's recent Ecological Land
Classification, 16 are considered significant
because they are rare (small area in park) or
fragile and threatened. Notable are two
grassland types and two types of aspen
forest. These are threatened by non-native
plant invasion, disturbance and heavy
grazing pressure. |
Waterton Lakes has over 1,400 forms of vegetation. In
addition, amongst Waterton's more than 970 species of
vascular plants, 179 species are rare in Alberta. Twenty-two
of these plants are not found anywhere else in Alberta.
Two of Waterton Park's more unique plant-life are
detailed below:
Moonwort
Waterton Lakes National Park has globally significant
genetic diversity, best symbolized by its amazing variety of
small ferns called moonworts. Waterton Park has 8 different
moonworts. The Waterton moonwort (Botrychium x
watertonese) is only found here and is considered the
rarest plant in the park.
Beargrass
Tall beargrass flowers (see above photo) and their tufts
of grassy leaves are Waterton Lakes National Park's showiest
plant. With its unforgettable torchlike cluster of white
flowers, each plant blooms roughly once every seven years.
Although not a synchronized bloom, some years are better
than most, with whole slopes covered with this
mountain-lily. Waterton Lakes is the only Canadian National
Park that protects this plant. It is the unofficial emblem
of the Waterton-Glacier International Peace Park.
Aboriginal poeples used their long basal leaves to weave
strong, watertight baskets. Beargrass' scientific name (Xerophyllum
Tenax) means "the dry leaf that holds fast."
Contrary to popular belief, bears don't have much to do with
this plant, except perhaps as bedding material. Deer, elk
and sheep nibble their blossoms, mountain goats eat their
leaves, and chipmunks and birds snack on their seeds.
