Question about Pine Trees
Posted on 3/17/21 at 4:43 pm
Posted on 3/17/21 at 4:43 pm
I have wondered for a long time now why do pine trees seem to grow in certain areas and not others? I'm sure soil and other factors play into good conditions for pines to grow, but I was just in NW Arkansas and noticed there will be a pocket of pine trees surrounded by hardwoods with no pines mixed in amongst the other trees. They seem to pretty much always be clumped together. Is there certain geologic formations they prefer to grow on? Can anyone please explain? TIA

Shitty dirt breeds pine trees. And meth and crossbows.

Nutrient poor soil is part of it. Sandier soils tend to favor pines.
It can also be the presence of a fire regime. If fire is common, most hardwoods will not tolerate that environment, which then tends to favor pine trees. Hydrology can also impact the trees (and plant community as a whole). Some pines, like Slash, tolerate more water than others, like shortleaf or longleaf. If you have fire and periodic inundation or saturation of the site, there will be very few trees at all, and mostly herbaceous vegetation.

Pine trees prefer sandy, well drained, acidic soils

Are you sure you aren’t seeing pine plantations?

It's complicated, but now that we have pretty much eliminated annual flooding, one can grow pines anywhere. Ellik is full of them now. Wasn't so before levee systems.

I just got back from Fort Myers and it looks like you could get a single 60' 2x4 out of those trees

SMZ’s possibly?

Where land has been cleared in the past and then allowed to return to wild after abandonment, pines will outperform and take over, depending on other factors of course.

They were probably planted

Pine trees don't grow in river bottoms, trunk is a deep spine, need broad roots to grow in areas that can flood...there is not a single pine tree along the Mississippi River that was not planted by a human

If not talking about flooding lands it is a matter off succession. Brush first, the pioneer species then hardwoods and then climax species.
Pines are pioneer species that take over after manmade or natural disturbances such as disease or fire.
Oaks (hardwoods) will then replace the pines as the pines can't regenerate and compete with the hardwoods when there is a forest already present.
Climax species such as magnolia are the final forest cover. These species do well in low light conditions.
So probably either logging or a fire removed the forest in those spots.
Of course in certain areas like high elevation, swamp etc pines or spruce cypress or whatever can be the pioneer as well as the climax vegetation all at the same time. That isn't common in the southeastern part of the country.

So, in short, science and shite is why.
Eco succession is an interesting topic though.
