A fully grown tree is a spherical structure up to a hundred kilometers across. It generally consists of 4-6 trunk structures growing out from a comet nucleus. Branches grow from the top of each trunk and intertwine and merge with each other to form a single structure. The trunks and primary branches are hollow and contain a breathable atmosphere and symbiotic ecology as well as a space adapted ecology on their exteriors. Various sub-species have been engineered to survive at a variety of distances from a star and under various wavelengths. Generally found at distances ranging from .5-4 AU around stars in the G, K and M class. Often a popular habitat for space adapted bionts.
Growth of a new tree begins when a suitable comet is diverted into a close solar orbit and a seed is planted on it. Over several years the seed extends a root system into and around the comet and then begins the growth of the primary trunk systems. Depending on the material supply in the comet and the distance from the star, full growth may take up to a century. However, most trees are ready for initial habitation within 10 years of planting. Average tree lifetimes run to a millennium even without life-extension bio-nano, and a mature may support a population in the millions.
In systems where the trees have been long established entire 'orbital forests', consisting of hundreds of trees spread across millions of cubic kilometers, may be found in the most desirable orbits.
The first experimental dyson trees date from as early as the middle interplanetary period. Unfortunately, none of the early trees survived the nanoswarms.
The idea was however popular enough to be taken up again by the First Federation, with diverted a number of comet cores from the Oort Belt. Unfortunately many of these cores had already been long populated by haloist clades, and most either wouldn't give up their cores, or did so only after exorbitant financial renumeration. A typical cartoon from the period showed a crusty skinny old microgravity-adapted space prospector sitting on a lump of ice, frowning, head turned away, arms and legs (prehensile feet) crossed, while slickly dressed developers in the latest Xoffona-6 suits wave wads of Fedcred in eir face.
Tree-based development projects only really took off during the age of expansion, supported by clades of the spacers and biotech megacorps.
These days dyson trees are very popular in the Zoeific Biopolity, the Utopia Sphere, MPA, the Negentropy Alliance, and the Sophic League. And since the seeds are relatively cheap compared to most technological solutions, and more reliable than a lot of nano, growing dyson trees has also become a common way of building a base in the outer volumes.
There are even wild versions of dyson trees. These propagate by
sending seeds that are propelled by solar sails, chemical rockets, or
even amat-propelled devices. Whole ecologies have spring up in some
star systems.
Whilst many trees away from the Nexus in the Inner Sphere and Middle Regions, and especially the Outer Volumes, are only lightly populated, many Trees in Nexus- (stargate) linked Inner Sphere systems are heavily populated, with a dense swarm of shuttles, ships, and other vehicles weaving among breaks in the foliage, along with docking stations, control towers, manufacturing faculties, clusters of space homes, water-filled diamondoid spheres glowing in the dark like blue pearls, others green like lush forests - little forests within a larger dyson forest - computronium banks, etc etc.
There are also be cyborg and bioborg trees and sub-trees - half organic and half artificial - trees that incorporate nano- and meso-fog, and innumerable other combinations.
Although some dyson forests have their own hyperturings and caretaker gods looking after them, only allowing in those sentients that will respect the trees and not turn them into glitzy tourist resorts, many are just places to live. Neither a space druid grove or sex parlour. But other hyperturings, especially in the NoCoZo, have deliberately seeded dyson forests for the purpose of glitzy tourist development a thousand years down the track). The (in)famous Makrania Orwoods around Frei (HJer-IV, NoCoZo) are well known across inhabited space for their zero gravity free-space casinos, sports and hedonics.
