| What
does riparian mean? |
Where
is the most effective location for buffers in a watershed? |
| How
long does it take for a buffer to reach its maximum efficiency?
|
Do
buffers really reduce nitrogen and other chemical loading to streams? |
| Haven't
nitrate levels always been high in Iowa and other Midwestern states surface
waters? |
Do
trees and shrubs really stabilize streambanks? |
| Can
grasses be planted first right along the bank to minimize trees falling
into the channel? |
What
should be planted if all or part of the riparian zone is in reed canary
grass? |
| Don't
trees plug tiles? |
What
are the shallowest rooted trees and shrubs that can planted so they can
be removed at a later date if necessary? |
| Can
direct seeding or natural regeneration be used to establish a buffer? |
Don't
trees attract beavers and don't they hinder water movement? |
| Do
buffers attract undesirable wildlife species (e.g. coyotes, deer, rodents,
insects)? |
Don't
buffers act as sources of seed for noxious weeds? |
| Isn't
there a problem with the buffers ponding water as a result of levee
formation along their edge and/or sediment trapping?
Or how do you keep concentrated flow channels
from developing through the buffer? |
Do
buffers require maintenance? |
| Can
buffers be grazed for short periods? |
What
provisions can be made for livestock access to water? |
| Are
wetlands really effective in reducing nitrate and other chemicals? |
Do
wetlands work during cold weather? |
| How
much land is going to be taken out of 'production' if buffers are installed? |
Wouldn't
it be easier or better to straighten the stream and rip-rap the stream
banks than leave it in its meandering form? |
| What
kind of government incentives are available for establishing buffers? |
Are
there products that can be derived from buffers? |
