so what we're doing it this experiment is
trying to figure out exactly
why and how tree style even though everyone knows that droughts
come along and vegetation dies
nobody yet can predict where when
how fast how well the idea is that these drought structures move about half of
the water that false a little rain or snow false here
it's all the way trains downhill
so that this ecosystem receives about fifty percent
the ambient rainfall this induces a drought stresses trees
in addition we know that when there are droughts it usually really hot
and we expect that to get much worse because all the evidence shows quite strongly
that there's temperature is going on
is and you never tree here
in study here we measured the water flows through the cheese
and everything is regulated by these temperature and humidity sensors which are designed to keep
the temperature in here about five celsius above and to choose
the air is blown and from h back units through these to these ducks
the other species were looking at here is the pinion time
juniper ending in point are very useful
study specimens because juniper is fairly drought tolerant although it does not very low but
not as much as pinion pine
which is fairly similar to most fines globally
this experiment is
a one of the current experiment in the sense of its size and its combination
factors manipulating
what's
completely novel about this particular experiment is that we not only have the drought structure
but we're also heating the trees
it allows us to really assess how things might function in the future
it's important for side be aware this i think because
myself and lots of others like really care about our force
we care about
or while glancing this if they're gonna be here for kids we will have to
make decisions as a society
to know how we're gonna manager in portfolio decisions we make with regards to
client
then walking enough and fortunate enough to have an amazingly good team great managers
excellent staff
excellent students postdocs we've been able to build together over the years
a program including this wonderful experiment allows us to really start answering these questions without
these experiments were not we can't really figure out
how trees die
so i'm extremely excited about this is really fun
