The tendrils hanging down are part of the tree's root system. If the maintenance crew didn't trim them, they would grow down to the ground and plant themselves, eventually growing like a new trunk from the original tree.
From a Hawaiian tourism site:
Cool down in the shade under one of the largest banyan trees in the United States. Imported from India and planted in front of the Lāhainā Courthouse and Lāhainā Harbor on 1873, this sprawling tree along Front Street is the size of an entire city block and stands more than 60-feet high. If you need to cool down a bit, you can walk for two-thirds of an acre under the shadow of its sweeping branches. Many events and art exhibits are held beneath this popular gathering place. At Art in the Park, which takes place every second and fourth weekend of the month, browse for affordable paintings, limited edition prints and a wealth of crafts under the dangling vines and twelve major trunks of this Lāhainā landmark.
I've been blessed to be there and see how the tree does cover such a large area. Out my back door is a Live Oak tree that has been shown to be older than this banyan tree. It qualifies to be included in the Live Oak Society, and its spread is 65 feet, with a girth of 9+ feet before the split, though not nearly 60 feet tall. Unlike this Banyan tree, ours doesn't put out limbs, then roots to start a new trunk on the ground, but it sheds acorns to start new live oak trees.
The Bible uses trees as examples in maniy verses, but one of my favorites is:
Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful. But his delight is in the law of the LORD; and in his law doth he meditate day and night. And he shall be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf also shall not wither; and whatsoever he doeth shall prosper. The ungodly are not so: but are like the chaff which the wind driveth away. Therefore the ungodly shall not stand in the judgment, nor sinners in the congregation of the righteous. For the LORD knoweth the way of the righteous: but the way of the ungodly shall perish. (Psalms 1:1-6 KJV)
In eastern California, a Great Basin bristlecone pine known as Methuselah has long been considered Earth’s oldest living thing. According to tree-ring data, it is 4,853 years old — meaning that Methuselah was well established by time ancient Egyptians built the pyramids at Giza. But wait — a challenger has emerged to vie for Methuselah’s record, reports National Geographic’s Craig Welch. In Chile, a Patagonian cypress known as the Alerce Milenario or Gran Abuelo (great-grandfather) could be 500 years older than the current reigning champion.
