Title: Montane Wetlands


1
Montane Wetlands
  • By
  • Jacob Wigginton

2
What is a montane wetland?
  • Montane means of mountains
  • High altitude pulustrine wetlands with emergent
    vegetation

3
How do montane wetlands compare to prairie
potholes?
Similar yet contrasting wetlands
4
Similarities
  • Pulustrine
  • Similar in appreance
  • Some are created by a similar glacial process
  • provide important habitat for water fowl

5
Differences
  • Montane wetlands are typically less disturbed
  • Montane wetlands are still dominated by native
    vegetation
  • Montane wetlands almost always have enough
    rainfall to acommidate ducks and geese
  • They also differ in soil types making the
    vegetation very different
  • Succession happens much slower in montane
    wetlands
  • Montane wetlands do not have as many high
    concentrations of waterfowl

6
What different types on montane wetlands are
there?
  • Intermountain Basin Wetlands
  • Beaver ponds
  • Glacial Ponds
  • Montane Depression Wetlands
  • Montane woodland seeps

7
Intermountain Basin Wetland
  • Flat or rolling areas created by tectonic and
    volcanic action
  • Thick underlying layers of alluvial material
    eroded from the mountains
  • High water tables are recharged in the spring by
    impoundments and artesian flow

8
Plants of intermountain basin wetlands
Monument Plant
Mint
Arrow Grass
Additional Species Black greesewood, saltgrasses,
wheatgrass, bluegrass, sedges, rushes, sage
brush, rabbit brush
9
Waterfowl of intermountain basins
Canada Goose
Cinnamon teal
  • Additional species
  • Gadwall, Northern Pintails, American Wigeon,
    Northern Shoveler, Redhead, and Lesser Scaulp

10
Invertebrates of Intermountain basins
Odonate larvae
Freshwater Shrimp
Midges
Diptera
11
Beaver Ponds
  • mid-elevation on gradients less than 15
  • Water levels maintained by percipitation and run
    off
  • Nutrients sinks trapping organic matter and
    sediments
  • Ideal waterfowl breeding area

12
Waterfowl of beaver ponds
Barrows Goldeneye
Bufflehead
Additional species Gadwalls, ring-necked ducks
13
Plants of Beaver ponds
Wild Licorice
Alder
Additional Species Flooded willows, sedges,
burreeds
14
Invertebrates of Beaver Ponds
Gastropods
Caddisflies
Dragonflies
Freshwater shrimp
15
Glacial Ponds
  • Formed either behind moraines or by a glacial
    process similar to the prairie potholes
  • Only occur in mountains and prairies
  • Only water sources are summer percipitation and
    spring runoff
  • Very old wetlands, peat accumulations in some are
    7,000 years old
  • Although absence of fish competition allows an
    abundant invertebrate population landscape makes
    it a difficult habitat for some birds

16
Waterfowl of glacial ponds
Ring-necked Duck
Gadwall
Additional Species Bufflehead, Barrows Goldeneye
17
Plants of glacial ponds
Southern Maidenhair fern
scouring rush
Additional species Pondweeds, watermilfoils,
cowlilies
18
Invertebrates of Glacial Ponds
Dragonfly
Caddisfly larvae
Misquitos
Coleoptera
19
Montane Depression Wetlands
  • Saturated, seasonally and semipermanently flooded
    vegetation
  • Occur in the eastern U.S.
  • Prononced seasonal water fluctuations
  • Important breeding habitat for amphibians and
    odonates

20
Plants of montane depression wetlands
3-way sedge
Winter berry
common green brier
High-bush Blueberry
Additional Species Virginia sneezwart, Virginia
quillwort, St. Johns Wart, Robbins Spikerush,
Black-fruited Spikerush
21
Trees of montane depression wetlands
Red Maple
Black Gum
22
Amphibians of montane depression wetlands
Salamander Eggs
Tiger Salamander
Spotted Salamander
Additional species
Jeffersons salamander, four-toed salamander,
marbled salamander, wood frogs, Upland Chorus frog
23
Invertebrates of montane depression wetlands
Crayfish
Odonate Larvae
Freshwater shrimp
24
Montane woodland seeps
  • Saturated herbacous wetlands
  • Occur in sinkholes or on steep, bouldered slopes
    at the site of water discharge
  • Western Virginia mountains
  • Above 2500 ft.

25
Plants of montane woodland seeps
watercarpet
Oswego-tea
marsh blue violet
Additional Species Cut-leaved coneflower, spotted
jewelweed, Rough golden rod, golden rag wart,
American false-hellbore, marsh marigold,
bluejoint reedgrass
white turtle head
26
Threats to montane wetlands
  • Proposed changes to the Clean Water Act
  • Overgrazing of Elk
  • Invasive Species

27
Clean Water Act Changes
  • Before the Clean water act only a third of the
    nations waters were safe and clean
  • Now half are clean and safe
  • Redefining wetlands to exclude montane wetlands
    would be a step in the wrong direction
  • Changes would leave Colorado with only fifteen
    miles of protected water

28
Overgrazing by Elk
This increase in has caused the problem of
overgrazing of riparian vegetation in the Rocky
Mountain region
In the 1960s a policy of natural regulation
which has led to an upsurge in the Elk population.
29
Invasive plant species of montane wetlands
lepidium latifolium
pittosporum_undulatum
Russian olive
30
Introduce trout
Brook trout
Brown Trout
tadpoles
31
Threatened, Endangered, or Endemic Species
montane wetlands.
32
Criteria for selecting wetlands of importance
  • Area that provides habitat for rare or endemic
    species
  • Area of rich biota
  • Area which provides habitat for considerable
    numbers of a specific species
  • Area that is indespensible in the life history of
    an organism
