Lecture 6 Flashcards
Shrubs
Sparrow’s egg lady slipper, found along the edge of the river.
Ninebark
more northern indicator plant
Willows
mediu, sized shrub willows, different from the dwarf ones found in the tundra.
Wolf Willow/Silverberry
dominant shrubs in the hbl, habitats for birds.
Poplars
pioneer species
Flowers
found deeper in the forest, not indicator species, only here because river provides habitat for trees, trees provide habitat for flowers.
Bunchberry
Explosive reproduction. Coniferous forest plant, found along the edge of the rivers.
Black backed woodpecker
most northern woodpecker. Males and females take turns during the day incubating the eggs, males incubate all night.
Gray Jay
common in the boreal forest, stores food everywhere to survive northern winters.
Snow shoe hares
mammal that eats spruce needles
White winged cross bill
live alongside the rivers because that’s where most of the spruce trees are
Red Squirrels
in the hbl because of the spruce trees.
Predatory Mammals in the hbl
Fishers, martens, wolverines
Attawapiskat River
found in the hbl, rocks are smooth and flat from glaciers. Sedimentary, so when you pour acid on to the rock is effervesces.
Sparrows
LeConte’s, Nelson’s,
other birds
lesser yellowlegs, short billed dowitchers, semipalmated plovers, least sandpipers,
red knot
champion of migration, the rufa species is endangered, fewer than 20,000 left.
Jelly fish
found in hb, because there is less salt there than james bay
The Sutton Hills
major hills in the hbl, found in the northern part of hbl. Different habitat, important for many things:
- mostly granite
- only real source of relief,
- nesting spaces for golden eagle
disjunct population
the main population of the species is located elsewhere. These occur because the population was all one at one time, but the climate changed. These populations are called glacial relics.
Rock polypody
grow on the Sutton hills, also a disjunct population
Boreal forest
on the Canadian shield, meaning very old acidic rock, either igneous or metamorphic. Lots of continuous forest and relief, 25% of Ontario. Dominated by coniferous trees and very old rocks.
Main trees in the boreal forest
- black spruce (spindly)
- white spruce (fuller body)
- balsam fir (skinny)
Boreal Forest Site Conditions
- relief provides a better drainage system
- no clay in the Canadian shield so better drainage
- less windy because of the relief
- warmer because it is farther south
- more decomposition, therefore better and richer soil for plant growth
- diversity of glacial deposits
