Temperate Rainforest Ecosystems Final

The Tongass is an important habitat for what animals

eagles, brown bears, and wolves

land mammal diversity in the tongass

30-35 species

Forest bird diversity

>350 bird species

how many bird species rely on the forest?

>120

Salmon diversity

5 types of salmon

tree species typically decline when you move

from south to north

Forest land in the mountains is typically

federal land

Forested land in the lowland area is typically

privately owned

The extent of forest protection increases from

south to north

the extent of forest development decreases from

south to north

Southern limit of the north american pacific coast rainforests

San Francisco, California

Northern limit of the north american pacific coast rainforests

Kodiak, AK

North American pacific coast rainforests comprise what percent of all temperate rainforests?

35%

Climate Moisture Index=

precipitation- potential evapotranspiration

Old-growth dependent species

northern spotted owl and marbled murrelet

Most timber harvested in the Western USA is from what states

Oregon and Washington

What state has the least amount of forest protection in Western USA

Oregon (9%)

Forests account for what % of surface drinking water in Oregon

78%

Carbon emission from burning fossil fuels and land use change are primary
causes of

rising atmospheric CO2 concentrations

CO2 and other “greenhouse gases” trap solar radiation in the atmosphere,
causing the planet to

warm

Global mean temperatures have warmed by how much over the past century

>1°C

T/F: Southeast Alaska is becoming warmer and wetter with (typically) less snow

T

T/F: Southeast Alaska forests have expanded and gained biomass in recent decades

T

Yellow-cedar decline is caused by

snow loss and freezing damage

Shore pine decline from

warmer, wetter nights

T/F: Novel insect outbreaks like hemlock sawfly have been documented in SEAK

T

Future warming and shifts in water availability depend on

carbon emissions

Temperate forest biome might contract overall with future climate change,
though minimal losses if

carbon emissions come down

Southeast Alaskan forests might be fairly resilient to

near-term climate warming
