Biology

The entire biosphere of Trilla bears witness to the full scale industrialisation of the ecology.  Much of the original biology of Trilla has been completely eradicated though many new species have been introduced, either from off-world or through the genetic manipulation of native organisms.  In particular all large predators have been eradicated as they would pose a threat to agricultural animals.  The ecology of individual regions is determined primarily by the agricultural activities in that region, with only the deep ocean and high mountain habitats separated from direct agricultural influence.  Much of the mid-latitude regions are given over to cereal production and livestock farming with a sophisticated rotation between different cereals and grazing to manage the soils of the region.  The Trillan grox sub-species comprise the majority of the livestock reared on Trilla, though in some of the more mountainous regions the hardier Glama is preferred.  A number of native bird species have survived in the mid-latitudes, though some have been subject to significant genetic manipulation, and are valued as they hunt pest creatures that damage crops.

In the tropical regions the most important crop is the native derived sap-cane.  Though sap-cane is derived from a native plant it has been so heavily engineered that it bears relatively little resemblance to the original organism.  Sap-cane consists of many tall, rapidly growing, woody canes topped with leaves.  The core of the canes is hollow and contains a sugary liquid that is refined to produce sugars and syrups, while the outer parts of the cane are used as animal feed.  If left to grow for longer the outer parts of the cane become woodier and are no longer suitable for animal feed, but are in some demand for use in furniture and for staffs and canes.

Many of the marine creatures grown in the aquaculture facilities originate from native species, but again have in many cases been the subject of extensive genetic engineering.  Particularly popular is the Islay Redwing, which can grow to almost 2 metres in length and has a tender pink meat.
