Definitions
• An Urban Forest is defined as a
dense population of trees in a city.
• This could be anything from
Olympia street trees to the TESC’s
forest reserves

Hypothesis
•Hypotheses: Certain species of trees can sequester more carbon than other
species
•Alternative: Non-Native trees sequester more carbon
•Null: All species of trees sequester the same amount of carbon

Field Work
•
•
•
•
Used diameter tape measures
Measured 3 of each species
Got an average DBH
converted inches to cm

Biomass Equation
•Biomass is the mass of organisms by area or volume
•It is measured for purposed of estimated carbon pools, estimate forest carbon dynamics at a large scale
and estimate carbon for research purposes.
Biomass Equation: bm = Exp(B0 + B1 lndbh)
•bm = total above ground mass (kg)
•dbh = diameter at breast height (cm)
•exp = exponential function
•ln = natural log base (“e” 2.718282)
Thuja Plicata
Western Red Cedar
• “Tree of Life”
• Tremendous spiritual significance
• Above ground biomass- 64756.93 lbs
• Carbon Sequestered -32,378. 46
• Average lifespan -220 years
• Mature tree sequestration rate- 147 lbs

Alnus Rubra
Red Alder
• Also called Oregon alder, western alder, and Pacific coast alder
• The Red Alder is the only commercial tree species west of the Rocky
Mountains with the capability to fix atmospheric nitrogen
• Relatively short-lived, intolerant pioneer with rapid juvenile growth

pseudotsuga menziesii

• The above ground biomass 149,887.9846 lbs
• 47,938 lbs
• Average lifespan -500 years
• Mature tree sequestration rate-149

•
the future of Douglas-fir in western North
America is highly uncertain due to the
expected changes in climate conditions.
•
analysis indicates a sensitivity of Douglas-fir
to climate and suggests that significant
changes in North America are to be expected
under climate change
•
By 2090, the amount of potential Douglas-fir
habitat is projected to change little in terms of
area (–4%). However, the habitat is expected
to shift from coastal areas of North America
to the interior
