Decades ago, with buddies while surveying the Willow Bay area of the Kinzua Valley dammed and become the Allegheny Reservoir just outside Marshburg, Pennsylvania, a large porcupine and progeny hurled themselves through the air to grasp a tree trunk high off the ground. The common interest was the same -- to ascertain just what type of hazards/dangers the new dam
had generated. Already, a fellow had 'forgotten' that some area roads no longer led into the game preserve valley, slated to be written up picture-book-style, but instead were suddenly submerged within tons of river water dammed.
Within the United States there are other habitats that have generated different sort of hazards and but similar types of dangers using transplanted palm trees -- a quantifiable percentage of such trees shipped in from mid-Pacific Ocean islands, bringing with them the attention of deep-sea creatures to North American ports-of-call. Other palm trees are planted in neat rows; with anthropomorphism largely decried, some populations choose to instead identify themselves with the palms in appearance and physical timbre as demonstration of symbiosis, without the historical comprehension that some adult palm trees are transplants from different ecosystems.
Which means, therefore, that the porcupine's behavior was appropriate, but that populations of human beings who purposefully fling themselves at palm trees can be a harmful displacement phenomenon and damned.
