A pictorial representation of some 
landscape components that sustain 
a high-quality environment. 
Riparian zones 
filter sediments 
and pollutants, 
especially in 
agricultural 
areas, in 
addition to 
providing 
important 
wildlife habitats

Large blocks of 
interior forest 
habitat are 
important for 
many forest 
species 
The number of 
forest scales 
surrounding a 
point in the 
landscape 
determines the 
variety of 
forest species 
found there 
Forest edge 
habitat is 
important for 
many species 
that require more

Forest connectivity 
is crucial for the 
persistence of 
forest species, 
especially in areas 
with moderate 
amounts of
