History
The Federation had no previous information on the planet prior to the six-week survey mission conducted by the USS Ariel in 2269.
Sensor scans later conducted by the USS Enterprise, supported by several surface contacts, revealed a variety of lifeforms on the planet from such planets as Canopus III and Maravel. Portions of Lactra VII were heavily terraformed, however, not done so in the traditional pattern, as several of the biomes seemed to be patterned at random.
Landing party observations made by the crew of the Enterprise noted that the planet featured several different ecologies co-existing significantly close to each other. One such example included a desert and a rainforest separated by a river. The water discovered on Lactra VII was clear and palatable, but was, according to Spock, "too pure."
Sensors later revealed a large concentration of lifeforms 98.5 kilometers northeast of the desert. Lactra VII was particularly well noted for having an immense zoo. (TAS: "The Eye of the Beholder")
