An Ecological Assessment of the Louisiana Tensas River Basin Chapter 1 
Humans reduce riparian 
cover along streams, 
which decreases 
filtering capacity 
Forest harvest 
practices influence 
forest connectivity 
and patch sizes 
Air pollution spreads 
across the landscape, 
affecting regional 
air quality 
Roads near streams 
increase sediment and 
pollution loads by 
increasing surface 
runoff 
Population growth 
results in loss of forest 
and changes in overall 
watershed landscape 
pattern
