Coeur d’Alene Salamander (Blue-listed)
The Coeur d’Alene Salamander is a Blue-listed species in British Columbia that occurs as
small, separate populations in southeastern B.C. Its habitat requirements include wet areas, such
as wet seeps, waterfall splash zones, and streamside riparian zones. As well, this salamander
requires rock formations with deep clefts or cracks that provide protection from hot dry
temperatures in summer and from freezing temperatures in winter.
Activities that negatively affect water quality and riparian habitats may be
deleterious to this species. Thus activities that reduce water quality and/or habitat composition
can increase risk to this species at affected sites. The consequences to local populations can be
significant because their distribution is characterized by small, isolated populations which are
more prone to local extinction than larger broadly distributed populations

Great Basin Spadefoot (Blue-listed)
Great Basin Spadefoots are amphibians primarily of
sagebrush flats, dry grasslands, semi-desert shrublands,
and open woodlands with sandy soil. They typically
breed in shallow ponds or temporary pools that dry
up by early to mid-summer.
In British Columbia, most sites are in the low-elevation
Bunchgrass biogeoclimatic zone, but there are
records of tadpoles in three lakes in the Englemann
Spruce-Subalpine Fir Zone within a few hundred metres
of steep, south-facing grasslands in the Montane Spruce
Zone.
The larvae are scavengers on algae, aquatic plants,
dead fish, and even their own feces. Adults forage
at night, eating a variety of terrestrial invertebrates,
and are themselves preyed upon by snakes, Great Blue
Herons, and Coyotes.
Breeding begins in mid- to late April, and can occur
as late as July, especially in wet, cool years. Females
lay 300–800 eggs in small clusters attached to
sticks, pebbles, or aquatic vegetation. The larval
development time is 6–8 weeks.
Potential concerns for this species include
encroachment on the areas around small ponds and temporary
pools in the dry southern Interior of the province
during breeding season and afterward while the adults
forage. Once the adults again burrow into the soil,
the threats to individuals are reduced.

Pacific Giant Salamander (Red-listed)
Pacific Giant (Coastal) Salamanders are species that
live in and around the cold mountain streams of the Fraser Valley. The larvae hide under
rocks, debris, and overhanging streambanks. Little is known of the
ecology of adults, but they presumably spend most of their time within the moss-covered soil of
wet forests, where they eat invertebrates such as beetles, spiders, and slugs but can capture
vertebrate prey as large as shrews, mice, and smaller salamanders. The adults are largely
sedentary, but on wet nights they can move several hundred metres, and often move 1500 metres
on successive nights. The adult females lay 85–200 eggs, singly or in clumps, in a hidden
subterranean or underwater nest site, and protect the eggs for up
to 7 months.

Painted Turtle (Blue-listed)
The Painted Turtle is widespread in southeastern North America, but
is restricted to valleys and lowlands across southern BC, from Vancouver
Island to the East Kootenay, and north to Williams Lake. The species
lays eggs in May or June in a nest dug in sandy-gravelly soils near
water.
Individuals often move between summer and winter hibernating
ponds. Turtles hibernate in bottom mud of lakes and ponds and emerge
with warming water temperatures.
Where motorized vehicles bisect travel corridors used by Painted
Turtles between their summer and winter habitats, there is a risk
that animals will be crushed. As well, activities that impact water
quality of both summer and winter waterbodies will adversely affect
turtles.

Snakes: Red- and Blue-listed species
Racer (BLUE), Sharptail Snake (RED), Night Snake (RED),
Gopher Snake -catenifer ssp.(RED), Gopher Snake - deserticola ssp.
(BLUE), and Western Rattlesnake (BLUE)
All three Red-listed snakes – Sharptail Snake, Night Snake,
and Gopher Snake catenifer ssp. – occur in and near
settlements and are therefore unlikely to be impacted by backcountry
recreation.
The catenifer Gopher Snake appears to have been extirpated
from BC.
Three snakes are Blue-listed: Racer, Western Rattlesnake, and Gopher
Snake (ssp. deserticola). All of these snakes occur in the
southern Interior of B.C., although their individual distributions vary somewhat. All of these snakes den
in winter hibernacula, sometimes with other species. They emerge in May and disperse
to summer feeding areas. These wintering sites are critical to these snakes
in coping with cold winter temperatures, and precautions are therefore required to
prevent damage to hibernacula. It is also important to minimize disturbance to emerging snakes.

Tailed Frog (Coastal:
Blue-listed; Interior: Red-listed)
Tailed Frogs occur in the Coast and Cascade
Mountain Ranges of western British Columbia, and in two drainages in the extreme southeastern corner
of the province. The two species live in cool, permanent mountain streams with stable substrates and
narrow temperature regimes.
Activities that damage the integrity of streams can potentially adversely affect
Tailed Frogs. Damage to riparian vegetation, stream banks and in-stream activities can increase
sediment loads, increase water temperatures and de-stabilize stream channels – all of which
may affect these species.

Tiger Salamander (Red-listed)
The Tiger Salamander is widespread throughout North America, but
the species is found in British Columbia only in the southern Okanagan and Similakmeen areas. Its main
habitats are in areas with lakes, ponds, or seasonal pools within the dry bunchgrass and ponderosa pine
environments. They typically breed in warm shallow ponds or temporary pools that may dry up by early to
mid-summer. Eggs are laid in April or May.
Commercial recreation concern for this species is encroachment on
the areas around small ponds and temporary pools during breeding season, and afterwards while the adults
forage. Adult salamanders do not range much beyond 150 m from their home pond.
Half of the original breeding habitat of the Tiger Salamander has
been lost because of habitat degradation and fish stocking programs.
Introduced fish in Tiger Salamander habitat are a major cause of endangerment
of this species.
