Water Locust (Gleditsia aquatica): Secondary Cleanup Operation (Updated)

As shown on a previous post, which you can read here, the arboretum lost an important tree this spring: our water locust (Gleditsia aquatica). The tree fell more than a month ago. Continued rainy, stormy weather has not allowed for a swift cleanup operation. Most of the damage, and specifically the hazardous parts, were cleared during the first week of May. More work remains.

Most of the water locust and broken yaupon holly branches were removed by the Centenary College grounds crew. Large pieces of the water locust trunk remain for observation. There isn't a hurry to remove the nicely shaped logs; however, the railing ought to be fixed soon to prevent an accidental stumble into the lower drainage basin. Note: the railing isn't meant to keep visitors out of the drainage basin—there aren't any 'off limits' areas of the arboretum.

As we see in this photo, there is a drop-off from the pedestrian area into the basin. The railing draws attention to the basin and prevents folks from haphazardly dashing off into the lower area. Also, a locust grew here, so there are plenty of dangerous spikes on the ground, hidden among the vines and irises.

Interestingly, when time came to saw the trunk that remained in the lower pond, fresh shoots were noticed. This part of the trunk was still attached to the in-ground root system.

Indeed, the water locust would really prefer to defy death.

Once again, the ground here is littered with nasty locust caltrops.


Here we can see why the tree fell. The entire root ball dry-rotted and turned to a spongy cork-like material.


Update: after a great deal of sweat and oil, the fallen trunk is gone. Only a series of blogposts remain.



Soon the undergrowth will expand to fill the empty space. In a year or two, this miniature glade will be choked out by undergrowth.



Our resident Arboretum Tabby is a great cheerleader and encouragement. "Good job," it says. "Just keep your distance. I'm feral."
