Lab Material Flashcards
What are the names of the dune plants we saw at blooming point?
Sea Rocket and Beach Pea
Grasses: cord and marram
What are the names of some of the wetland emergent plants we saw?
- Giant burr-reed
- Soft rush
- Bull rush (actually a sedge)
- Broadleaf cat tail
What are some of the aquatic plants we saw?
- Duckweed
- Pondweeds
- Cow lily
Digger Logs
- Logs placed in streams to direct water flow which creates a meandering pattern over time
- Sediment packed on the upstream side of the log (as a ramp) to direct water flow over top
- Creates spawning habitat for trout
Cover Logs
- Stray floating logs
- Provide salmon fry with protection from predators
- Salmon and trout require cover for spawning
Brush Mats
- Using conifer tree boughs (old Christmas trees), wooden stakes, and twine
- Prevents further erosion of river banks
- Helps prevent sediment deposition so that gravel is available for redd building
Rock Gabion Baskets
Galvanized metal baskets filled with rocks and placed at the bottom of eroding slopes
Wing Deflector/Channel Deflector
Structure that extends out from the banks of a river and deflects the direction of water flow
Check Dams
Reduce flow velocity and allows sediment to settle
Encapsulating Trap
Trap used for raccoons because they have a large amount of sensitive nerve endings in their paws meaning leg traps are inhumane for them
Laird Pond
- Manmade impoundment system that creates wetland areas and promotes fish movement
- Lead to dams
Relief Area
Downwards flow area in an impoundment system that relieves the water pressure downstream
What is the purpose of Mooney’s pond?
- Semi natural rearing facility for raising fry
- Has a burme dam
What type of tree species are found at Mooney’s Pond?
- Red maple
- Sugar maple
- Oak
- White pine
- Balsam fir
Aquifers
Oxygenate and cool spring waters
- Aquifers under pressure cause bubbles to rise to the surface
Standard Leg Trap
- Used for muskrats and mink
- Trap has no teeth and no jagged edges
- Sometimes attached to a wire with a locking mechanism, leading to water. This drowns them
Modified Leg Trap
Same as the standard leg trap but has a bar on the top that allows for more skin grab
Conibear Trap
- Rotating jaw trap for muskrats
- Snaps neck/collapses lungs for instant death
Indian River
- Protected wildlife area with a slot fish ladder
- Emergent plants: cattails
- Resting/stage area for waterfowl
Scales Pond
- Burme dam gave out ~10 years ago and was rebuilt; used to regulate water level in pond
- Originally built for hydropower
- Vertical slot fish ladder
- Leads to an arched culvert
West River System
- Uses a box culvert with Timbers and a perched culvert (downstream area)
- Contains a series of rock dams to maintain water level
- Vertical slot fish ladder
- Circular culvert
Clyde River
- Undersized corrugated curve culvert
- Causes the water to move in onion patterns
How can we tell the age of beavers by looking at their teeth? Describe from Kits to Year 4.5.
By looking at the roots of the teeth.
Kits: milk pre molars are still visible
- 5 years: roots of all molars are wide open cylinders
- 5 years: roots of molars are smaller in the size of the root opening but there’s still a visible hole
- 5 years: pinholes in premolars and second and third molar. The first molar is closed off with cement
- 5 years: no holes in the roots of the molars
What would the tooth from the jaw of a 2.5 year old deer look like?
It would have six fully erupted teeth on both sides of the jaw (3 permanent pre molars and 3 permanent molars). Premolar 3 now has two cusps.
What would the jaw from a yearling deer look like?
Generally it would have six fully erupted teeth and premolar three with have three cusps.
What would the teeth of a 3.5 year old deer look like?
The dentine is now wider than the enamel on molar one, and molar three has flattened cusps.
What would the teeth of a 4.5 year old deer look like?
Dentine is now twice as wide as the enamel on molar one
