Propably for some time if you run some data signal on that line 
that can run this long distance. Normal Ethernet connections 
and normal CAT5 networking techniques are designed so that 
the cable runs are maximum 100 meters. That's how in building 
wirings are built. 

You can't run normal Ethernet signals 1000 meters through 
CAT5 cable. You need to use some other communications 
technology that can go 1000 meters. 
Technologies like ADSL, VDSL, LRE etc..

If you just take a normal inside house CAT5 cable an run it 
through the trees outside, then don't expect long life. 
The outside climate conditions will quite quicly make 
an inside house wiring cable bad. I mean climate conditions 
like UV rays from sun damaging plastic materials, 
humidity and rain water getting inside cable and maybe absorbing 
to insulation, wind shaking wire here and there, mechanical 
stress of long cable hanging between trees, at winter time 
freeezing ciold weather can make the plastic material on cable 
brittle/fragile so that it will break down when cable is moved... 

Then take into consideration also the potential dangers of 
lightining hitting your cable (will fry the cable 
and equipment on both ends) or nearby your system 
(will easily cause several kilovolts surges to cable).

A drill is a nicer way to make a small home that will pass the cable 
from outside to inside.
