I don't think those are trees, but rather if you were to consider the scale and angle those are likely to be erosion features. But what does an
erosion feature usually imply? Water acting on the surface topography in some form.
Yet I think this could still be indicative of surface life, because of the possible presence of water. Not that what is seen is one giant plant, but
rather the darker coloration could could be a bloom of activity where moisture may have been most present and that's where the water pooled and ran
down before soaking in or evaporating off once again. So the possibility of some kind of "Martian Lichen" might be an interesting idea to pursue.
There's also the small chance that such a thing could have been seeded from our own planet due to meteorites or what have you.
And some food for thought...
This photo is taken here on Earth and from what I understand, not all that black stuff on the glacier is just dirt collecting from wind blowing over
it. Some of it is micro-organisms growing on or in the ice itself.
The info on the above link is kind of interesting, particularly when considering how some plant would survive in a cold and dry climate where water
can sublimate rather easy.
And that link suggests that some things may be able to live on Mars, even if it didn't originate there.
I'm not saying that stuff pictured in the Mars photo is life, but I still wouldn't rule it out. I'm sure some NASA guys would be considering it
along those lines, but to be scientific such hypothesis still needs validation and verification. Until there are enough samples or scans made using
known workable methods, it still wouldn't be possible to say in the affirmative.
