rocky mountain national park in colorado appears majestic in person
what is everything truly can harmony
ammonia a basic atmospheric dance vid grid lock stock and other forms reacts in the air
with nitric acid from cars and other combustion sources
this reaction forms nitrogen particles which report on the ways and in deposited in the
park
as a result the parks fragile ecosystem is changing
falcon livestock operations help preserve this national treasure
the park service has been doing research at the rocky mountain national park for over
twenty years now and what they families very soon
rising in mind that nitrogen even in the area of low wanted to use is causing changes to
be ecosystems in areas that the public normally think says christine
were not necessarily as christy and as we are hoping might be
when visitors come to the park it's sometimes hard for them to see what might be happening
in the water rb low ground or in the air that they don't necessarily see with the naked
eye
the colorado department of public health and environment has
done and the monument or even as an estimated sixty percent of the ammonia missions in the
state of coming from agriculture
with twenty percent coming from fertilizer and forty percent coming from
livestock production
now we're we're faced with something that's almost invisible last
nitrogen that position as the result
so it's a new back first
fruitless
the work of atmospheric scientist
internal chemists is focusing on
does that really come from
and one of the sources there are lots of sources of ammonia but and this is
the second most important
deposition password was what systematically
coming mainly from
probably
combustion sources
once the money moves into particles that can have a lifetime under weekend that might need
transport
over distances
thousand-mile trip perhaps more
how's your mom missions to come back to sleep on it
combustion sources like vehicles and industry released nitric acid hydrocarbons into the
air
at the same time nitrogen fertilizers agricultural fields golf courses and fall
along with maneuver from livestock
at least ammonia care
ammonia gas reacts in the atmosphere with nitric acid and hydrocarbons to create very
small nitrogen particles which are very through the air for long distances
these nitrogen particles can be deposited anywhere
even fragile ecosystems
this resulting nitrogen enrichment
can have a unintended effects on the surrounding environment
we have high ammunition from went wherever there is
hi amount of minority women owned accumulated like in manure storage
or treatment facilities
where women are just to have built up inline
back we estimate that now nitrogen is about twenty times higher than it was under natural
conditions historically
and then nitrogen is costing changes in the park these communities don't have much it
has to be picking up my tenants use nitrogen
there for the nineties and entertaining and
news is likely to change the standards used her only hot significantly
the levels of sound while from an agricultural standpoint
their only in the range of like three to seven hundred and return but because of the fragility
of the legal systems out there
and there's very little buffering capacity
and and and and that's not only that having margin
the in alpine metals princeton's
nitrogen excessive fertilizer any favor some plants over other planes we'd seen has a slight
stand brownian wildflowers perspectives grasses instead
on this changes the will source of the small mammals on the net area and it just doesn't
seem to be dynamics up uses then
negative also gets instantly streams attracting
and causes strangers
in the food webs in those lakes and streams phytoplankton the algae that i have a sense
of the chain in those lakes has been changed over the years
and when we see changes stainless steel west excommunication
vignette the insistence on the part of the impact and
well as a producer i'm i'm part of colorado reports
follows ever function
visit implicated as a contributor
student is in the position for we brought in and are agricultural community
and began talking to them from concerns of mexican are with their finances sometimes
it is not very often
camps
you cannot smell message in the position that this if you have small
all levels of phone problems this storm
and sources on them
intensive
some people automotive and tell people are still questioning how responsible they are
and they're going to tear
seasoned veterans
of their role before they're going to be very different thing
for someone who wants that is
how barger contributions and visit them
itself
part of that paul there was a lot of problems
believers
a lot of people to accept their heads
and that's
reflow last hope
house close enough comes out of this
how this material from the east and that moving back to the west and potentially impacted
by spectra or uh... in writing that nasa for prevailing winds as in most of the country
are from the west
but there are certain conditions that since his arrival of needs
backups
against the mountains enough
they really are too
uh... main kinds of scenarios that could explain how material from the east is transported
towards the west and backup right now
park
one of those their upload
smells cesar very typical events especially in the spring style
the reason that the air moves in mysterious friends east-west
ass to do with low pressure center city
and the move across the southern part of the state of colorado
the air around the low pressure at the surface is flowing counterclockwise areas wrapping
around them
backed up against the mountains and produced very heavy
the others in the area that we're interested in that brings there from the keys to the
west
is more important than this summer
and missus what we refer to as the mountain valley when circulation
uh... during the summer when the heating from the sun is strong
as that keeps them out in the year in contact with the mountain warrants expands during
the day that
feeding leads to a flow of the house will
at night the reverse pattern first were apparent contact with the mountain slope pools
rather quickly
and you get cancer at the fence
fanciful kind of like the river back down
along the mouthful
so it's pretty much every day in the summer
uh... on the east slopes of the rockies lucy air comes from the east
go to the west up along the maps slope
what we saw with some of our real-time measurements when the first which
to coming from the east
you first saw concentrations uh... among them and i say destefano
and other things increased quite dramatically
and then once of precipitation started
we saw a large what city materials as they were being scavenged from the air masses positive
his assistants what's happening in ecosystems of acting out
justification for that because that might be happening in other places outside the park
itself
the air does not rise to the state andrea start for instance
all fall out with the agency's statements is headed
so we really need to understand
more about regional sources
larger scale sources
should have been many best management practices
that have been hypothesize are being tested in laboratories
but haven't really been tested under field conditions what we're doing is we're taking
as the practices
advancing on an electorate laboratory select
for putting those out real-world farms
and i'm really upset
unconstrained concerned wealth observing nitrogen
finished unchanged
even last night of june and right now in this state division very profitable
this medicine practices camille
launceston
theatricality teacher
and uh... at the same time at his feet
moon in nineteen seventy seven fax that management practices that we're looking at
all right hand side effects i think that is the fairies
hi there any successful surface
mitigation feedlot
uh... different ways to manage compounds cambodia
things like that practice
that where we have enough and now
of the money missions prayer when you're likely f_a_a_'s are successful at reducing emissions
from there also practical cost effective and efficient or operators two years
family
recommend those two are still at five fifty years on that
so we
have both livestock
crops efficient sit-down he have developed implanted nicely voluntarily acacia editions
and he sees
responsibilities
as many changes improvements is fixed now
but we found that christian ariel thanks
working like that candidate willing to adopt packages should be seven cash in on upon practical
and there are gonna make it
oftentimes and people think of national parks
their lives that they're part of the bigger picture
when we deal with issues like atmosphere physician at any time
finishes
emphasized at national parks and not in a bubble but they certainly are impact despite
what's happening
programs
so i think we have to be open
practices financially
and stewards of
now clear enough
not only to a neighbors but
through our state
in
mainland
and no new
