Black Bears & Bear Attacks

The American Black bear is the smallest & most common species of bear. They are omnivores, so their diet is dictated by the season; i.e. new shoots, berries, roots, spawning fish. They live in forested areas throughout North America.

With man encroaching more and more into bear territory either through interface communities or hiking trails, encounters with bears will continue to increase.

This video of a sow with her two cubs was filmed at Hardy Falls (also known as Deep Creek), British Columbia. Hardy Falls is a popular walking trail into a densely forested area.

"We had gone our for a walk to the falls. About a third of the way in, another walker heading back to her car, informed us that she had spotted a bear up on the ridge above the path. We proceeded cautiously until we saw the sow and one cub, then the second cub. They were descending the steep slope down towards the creek and path.

We didn't move any closer, but continued talking and making noise, to let the bear know we were still there. More walkers gathered, and we all stayed a safe distance and ready to leave."

Black bears rarely attack when confronted by humans. At the same time, it is common knowledge if you live in bear country, that a sow with her cub(s) is potential danger. They are wild animals & will be protective of their young.

Coming between a sow and her cub(s) could spell disaster. There also are times when the family pet can be a real danger around bears. This happened recently with a Tappen man.

The attack happened last Saturday, near Tappen. According to Conservation Officers, while out on a walk, the Tappen man's dogs treed a bear cub and while the man tried to pull his dog away, the attacked. The man was knocked to the ground, mauled 3 times and only after fighting back, was he able to get free. The sow and cub ran off. Later at hospital, the man received 50 stitches for injuries to arms, chest & hands.

The bear will be tracked and possibly relocated. The Conservation Service recommends a few simple rules to observe when walking or hiking in our great outdoors:

always be aware of your environment - things around you
make noise so you don't startle bears
if your dog is not voice command trained, keeping it on leash is advised

Calypso bulbosa var. occidentalis Orchid - Western Fairy Slipper or Venus's Slipper

Orchid Love?

Calypso orchid (Calypso bulbosa) is beautiful!

The following video is of the Calypso bulbosa var. occidentalis Orchid or calypso orchid that we came across June 3, 2011 in the Kentucky Alleyne Provincial Park of British Columbia, Canada. You can't imagine how excited we were to find it! Another YOLO experience!

Directions to the park:

38 km south of the city of Merritt or 11 km south of community of Aspen Grove,
just off Hwy 5A.
From the east, the park is 11 km. from Coquihalla Highway 97C on paved access.

The closest communities, towns and cities are Aspen Grove, Merritt, Princeton and Elkhart Lodge. See the link for maps.

Also know as Fairy Slipper or Venus's Slipper

a few facts . . .

The Calypso orchid (Calypso bulbosa) is a perennial member of the orchid family found in undisturbed northern and montane forests.

It has a small pink, purple, pinkish-purple, or red flower accented with a white lip, darker purple spottings, and yellow beard.

Calypso orchids are typically 10 to 14 cm in height.Their little purple blooms can be a pleasant sporadic sight on hiking trails from late March onwards, though in the more northerly parts of their range they do not bloom until May and June. The plants live no more than five years.

Where are they found?

We found these by a happy accident!

As it is the only species currently in the genus Calypso, (which takes its name from the Greek signifying concealment) they tend to favor sheltered areas on conifer forest floors. That's exactly where we found them. The specific epithet, bulbosa, refers to the bulb-like corms.

This species' range is circumpolar, and includes the western states and most of the most northerly states of the United States; Canada ; Scandinavia (northern Sweden and Finland), the northern part of European Russia; eastern Siberia; and Japan—see external links for map. Four varieties are recognized: var. americana and var. occidentalis, which are found in North America, respectively east and west of the Sierra Nevada ranges; var. bulbosa in most of the Eurasian range; and var. japonica in Japan.

Threatened and Endangered!

logging is a serious threat . . .

Although the calypso orchid's distribution is wide, it is very susceptible to disturbance, and is therefore classified as threatened or endangered in several US states and in Sweden and Finland. It does not transplant well owing to its mycorrhizal dependence on specific soil fungi. The corms have been used as a food source by North American native peoples, though this is not recommended now because the sites for these plants are now rare and easily destroyed. The Thompson River Indians of British Columbia used it as a treatment for mild epilepsy.

Their beard serves a purpose -

The calypso orchid is most often pollinated by queen bumblebees. It relies on "pollination by deception", as it attracts insects to anther-like yellow hairs at the entrance to the pouch and forked nectary-like structures at the end of the pouch but produces no nectar that would nourish them. Insects quickly learn not to revisit it. Avoiding such recognition may account for some of the small variation in the flower's appearance.
