tag workflow: ID "die-off" of trees methodology

RECTANGULAR DIE-OFF OF TREES

 

Google Satellite shows entire area green-living

too uniform to be natural die-off?

notice how die-off does not quite reach road,

possibly to hide die-off "ugliness" from view??

preparation for construction?

what method likely used?

herbicides?  other? (no blackened trees = not via fire?)

authoritative comments from anyone familiar with this process appreciated...

In the West this would be Bark Beetle.

Along the Blue Ridge it's the Balsam woolly adelgid.

I would search along these lines with the exact location included.

Authoritative? Not really, just talk to angry Rangers.

 

edit2:

Just noticed the date.

Have you considered that rare natural phenomenon called Autumn or even Winter? ;-)

Why square? Different trees in different plantations.

Why the evergreens around it? Could be by design; could be invasive species and insufficient forest maintenance.

Not authoritative but my bet would be that it is water related - higher water table, inundation, salt water ingress. Roads and boundaries on raised banks.

Hurricane damage due to salt water?

Maybe Aliens have had enough of crop circles and are now doing squares

Thanks for responses.

No news reports of beetles killing off large lots of trees in South FL, AFAIK

(this lot about 70 acres, AFAICT)

Salt water interesting, but untouched fringe bordering roads doesn't appear

to be raised, also other large lot, same trees, conditions, untouched...?

invasive melaleuca in FL being exterminated, but never seen it on barrier island...

2 side by side lots

smaller bottom lot shaped like stumpy handle Nebraska now dead...

This is the sort of question Rangers love to answer. Honestly.

Just find the ranger station that's responsible for the area.

 

Re the salt water: according to this article there was too much (contaminated) fresh water this year when Irma made Lake Okeechobee spill over.

I lived in Florida for 14 years, but no authority other than that.  It looks like cyprus trees that have gone dormant for the winter to me.  Not unusual at all and they are quite ugly when they've lost their green.  Its obviously low land and probably swampy which is their habitat.  I don't think this is any kind of ecological disaster, unless you consider winter a disaster, and I DO.  :D

 

My 2¢.

You’re right. My next door neighbor had a cypress in his front courtyard until I complained to him that I couldn’t plant flowers in my beds because of all the cypress knees invading us. Tilting our brick courtyard wall and threatening the corner of our house.

He just sneered at me (a pastor, no less) until he saw me documenting it with my camera. He cut it down.

 

In the winter the fine foliage of the cypress turned a nasty orange color like a dead pine tree.

Don't forget that on the borders of woods other plants are able to grow as there's more light etc.

Thanks for further comments.  Some points:

 

a. not state park land, no rangers (seems to be private club land)

b. bordering northern lot seems to contain same varied trees, none dead

(suggesting man-targeted event?)

c. Google street level view bordering lot does not show any cypress AFAICT:

Could be that the effected trees are in an enclosed area that has been water-logged ( hurricane Irma?) and because of insufficient drainage outflow has not drained fast enough/fully enough, maybe outlets were damaged/blocked or amount of water unprecedented. 

 

Sea level is rising too reducing outflow, raising water table, and depending on the system allowing saltwater to flow inland along drainage channels. Does Google of sediment at drainage outflow suggesting soil erosion and possible constriction of inland channels?

 

https://www.usnews.com/news/best-states/florida/articles/2017-07-22/sea-level-rise-is-accelerating-in-florida-scientists-warn

 

Add in increased abstraction of fresh water for modern development

 

.....and this causes saltwater intrusion ...possibly:)

 

That is a working hypothesis anyway.

border between dead lot & larger live lot seem to be nothing more than sandy path:

https://goo.gl/maps/1VLTzmvTf5A2 (zoom to see path better)

may add some posted ideas as "possibly..." but my opinion still

its all too neat not to be man-made...

Ha.  Just called "Jensen Beach Club" east side dead lot,

they are SHOCKED to hear entire lot is dead, didn't know...

not their land, said maybe county's land...

Nobody wants to take responsibility for the environment do they?

It is these roads, tracks, sandy paths that enclose the land and prevent the natural drainage that would have naturally occurred in these low lying coastal areas. 

 

I think you are probably correct that this is a man-made environmental issue.
