Temperate forests are located between tropical and boreal regions with an average temperature of 10°C and rainfall of 30-60 inches. They support a wide range of plants and animals. Tropical seasonal forests are located in tropical zones between 10-23° latitude with average temperatures ranging from 21-29°C and rainfall of 9-98 inches. They support huge biodiversity but have distinct wet and dry seasons with less sunlight reaching the forest floor. Both forest types are threatened by deforestation and pollution.

2. Temperate Forests Tropical Seasonal Forests
Found between the tropical and boreal regions.
Average temperature being 10ºC
Exposed to both warm and cold climates,
temperatures fluctuate significantly
Supports a wide range of plants and wildlife
30-60 inches of rain
Found in many parts of the tropical zone
Ranging from 21°C to 29°C degrees
The 12th largest biome
Supports a huge range of fauna & flora
9–98 inches of rain
Deciduous Forest:
= “fall off”

3. Location & map
Temperate Forests
- Between the equator and North and South pole.
- Eastern Northern America, Europe, Eastern China,
Southern Eastern Australia, Japan
Latitude: is an angle ranges from 0º to 90º to the equator.
- Temperate forests are typically found 25º - 40º
latitude
- Near the equator due to the amount of rainfall
and the amount of insolation these areas receive.
Tropical Seasonal Forests
- Southern Mexico, southeastern Africa, central
India, along the coasts of Ecuador and Peru.
Primarily between 10° and 23°N and S latitude
Latitude: 10º to 15º degrees latitude of the equator.

6. Limiting abiotic Factors
Temperate Forests Tropical Seasonal Forests
Sunlight
- Older and taller trees soak up the sunlight
- Grass and ground plants struggle to absorb enough
sunlight.
Rainfall
- Temperate forests are heavily reliant on rainfall.
- Soil is wet/moist
- Without rainfall for a short period of time, it is easily
affected.
Sunlight
- Tall trees create a dense canopy which limits the
amount of sunlight that reaches the forest floor.
Soil
- The soils tend to be acidic which also limits the types
of plants.
Rainfall
- The time of year when the least amount of water is
available limits the vegetation in that given area

7. Nutrient Cycles
Temperate Forests Tropical Seasonal Forests
B = Biomass
S = Soil
L = Litter
R = Loss by Runoff (water running off land)
Le = Loss by leaching (loss of soluble substances
P = Gain from Precipitation. (water released from
clouds)
W = Gain from weathering (breakdown of rock
minerals)

9. Anthropogenic
Temperate Forests Tropical Seasonal Forests
Deforestation:
<10% of California, Washington
and Oregon native temperate
rainforest remains.
<3% of Australian Temperate
rainforests remain.
Biodiversity loss
- Hunting and poaching lead to
biodiversity loss.
Pollution
- Contaminates water sources.
- Contributes to ecological
imbalance.
- Pollution in the air contribute
to acidification of rivers and
lakes
(Ewa, n.d.)
(McGuffin, 2017)
Deforestation:
- Logging and slash-and-burn
agriculture have started to show
its effects on the rainforest
ecosystem. It is estimated that
the total area of the planet
covered by tropical rainforests
alone has decreased from 14%
to 6 %
Biodiversity loss
- Hunting and poaching lead to
biodiversity loss.
Climate Change
- Reducing the amount and
availability of habitat.
- Expected to rival land-use
change as the most important
impact on tropical forest
biodiversity.
