Slideshow Content
Why is forest conservation important? Selecting, evaluating and prioritizing sites
for conservation Summary
Forests can:– Reduce stormwater
runoff– Provide wildlife habitat
and migratory corridors– Improve air quality– Reduce urban heat
island effect
Fragmentation reduces interior habitat
Why is Forest Conservation Important?
Table 2. Hydrologic and Water Quality Benefits of Trees
BenefitPer Tree Annual Quantification
of BenefitSource and Description
Rainfall Interception 500 - 760 gallons of water Annual rainfall interception by a large deciduous front yard tree (CUFR, 2001)
Evapotranspiration 100 gallons of water Transpiration rate of poplar trees for one growing season (EPA, 1998)
Nitrogen Uptake 0.05 pounds nitrogen Based on daily rate of nitrogen uptake by poplar trees (Licht, 1990)
NOx (from air) 1 lbs per year Component of acid rain and nutrient runoff (CUFR, 2001)
O3 (Ozone) 4 lbs per year Ground level ozone hazardous to human health (CUFR, 2001)
Particulates 3 lbs per year Pollutants are linked to respiratory problems (asthma and diseases) (CUFR, 2001)
CO2 48 lbs per year Increase is root cause in climate change (CUFR, 2001)
Carbon 13 lbs per year Carbon sequestration by tree incorporation (Coder, 1996)
Temperature reduction
Reduction of 3 to 8 degrees Celsius (multiple trees)
Multiple benefits for health, reduce energy costs, stream temp (CUFR, 2001)

Step 1. Desktop Analysis Step 2. Field Assessment Step 3. Prioritization
Step 1. Desktop AnalysisReview Inventories:•US Fish and Wildlife•NWI•Natural Heritage Program•State resource agencies•Local planning office•County inventories•Historic site registries•Breeding bird surveys•Studies by universities or otherinstitutions
Obtain Mapping:•Wetlands•Forest•Aerials•RTE Species•Land Ownership/Parcels
