Editing 2715: Pando

This comic was the [[:Category:Christmas|Christmas comic]] of 2022.

{{w|Pando_(tree)|Pando}} is a {{w|Populus tremuloides|quaking aspen}} tree colony in {{w|Fishlake National Forest}}, Utah. Depending on the measurement method ([https://www.youtube.com/watch?v=vWAA-SrrFUQ there being various options]), Pando is the largest living organism on earth, and is thereby also the largest tree on earth. By dry mass (mass not including water), Pando is the largest living thing humans have found. There is [https://www.forbes.com/sites/linhanhcat/2019/02/22/largest-organism-in-the-world/ one fungus in Oregon] which may weigh more including water, but a fungus is [[1749: Mushrooms|not a tree]].

Pando is a tree colony, a type of {{w|clonal colony}} made of trees. Clonal colonies all form from the same seed or other origin, and are all genetically identical. Tree colonies spread using their extensive root system. Under all trees are {{w|Root|roots}}, which gather nutrients and water from soil. On clonal trees (such as the {{w|Populus tremuloides|quaking aspen}}, Pando's species), when roots from one tree surface they can form another stalk/tree, remaining the same genetic stock; this is unlike propagation by seeds. This clone then grows its own root network and is part of the clonal colony. Crucially, the linking roots between 'generations' of the plant do not naturally separate, so all effective clones stay attached. Each such stalk still has an individually limited lifespan of decades to centuries, but the colony can persist and propagate in this manner for millennia. For example, the only known wild example of {{w|Lomatia tasmanica|''Lomatia tasmanica'', also known as King's lomatia}}, is a clonal shrub thought to be at least 43,600 years old, and Pando itself is thought to be around 14,000 years old.

{{w|Christmas}} is a celebration on the 25th of December, traditionally commemorating the birth of {{w|Jesus}}. The celebration is often claimed to be built heavily upon pagan traditions,[https://chefin.com.au/blog/these-6-christmas-traditions-are-actually-pagan-customs/] (though this is disputed by some historians[https://historyforatheists.com/2020/12/pagan-christmas/]) as well as on annual social customs. It has evolved into a more secular event for many. This comic was published on the 23rd of December, two days before Christmas, or [[Christmas Eve Eve]].

The concept of a {{w|Christmas tree}} is rooted<!--No Pun Intended--> in various pre-Christian folkloric traditions and, in the modern era, may be adapted or adopted as desired by local and personal circumstances. It need not be an {{w|evergreen}} tree with an angel or star atop, though that is the oft-depicted image, but can be any handy plant or artificial substitute strewn with decorations and/or {{w|Christmas lights|lights}} as the owner wishes. People and places often compete to hold the record for the largest Christmas tree. At time of writing, the officially tallest Christmas tree was a 64.36 m (221 ft) tall {{w|Douglas-fir}} that was displayed in {{w|Northgate Station (shopping mall)|Northgate Shopping Center}},{{Actual citation needed}} Seattle, WA in 1950.[https://www.guinnessworldrecords.com/world-records/77271-tallest-christmas-tree][https://www.historylink.org/File/21359] The one with the most area is likely the [https://www.italybyevents.com/en/events/umbria/world-largest-christmas-tree-gubbio/ Christmas tree display] in {{w|Gubbio}}, a town in {{w|Umbria, Italy}}, where hundreds of trees on a mountain face are lit up with light to form a Christmas tree shape.  

In this comic, [[Randall]] proposes putting Christmas lights all the way around Pando to turn it into (technically) a Christmas tree. As Pando is the world's largest tree, if this plan were carried out, it would safely take the record for largest Christmas tree and hold it for quite some time. In the inset map, Randall has drawn the path of the Christmas lights as a {{w|convex hull}} around the edge of Pando. [https://www.google.com/maps/d/edit?mid=1Wgz5CxvxHC7FKMHWp5zkPQuQsZevBqU&usp=sharing Roughly tracing Pando on Google Maps] reveals its perimeter to be roughly 2.77 km or 1.72 miles, or roughly 9,000 ft. Allowing a little wiggle-room for differing levels of accuracy, and possibly the extra length required to suspend the shallow {{w|catenary}} loops of the lights and wrap them around the various supporting branches, 9,300 ft of Christmas lights seems about right.

The title text suggests that similarly to how trees that make up Pando are interconnected by underground roots, the gifts under the proposed Christmas tree are interconnected by underground ribbons. It may also be a reference to fungus, which often grow beneath trees, and can be connected by vast underground mycelial networks, suggesting that the christmas presents are the fruiting bodies of a similar network (perhaps a reference to [[2246: Christmas Presents]]).
