History and specifics[edit | edit source]
A high grass dominated the planet's primary continent, but was kept in check by being the main source of food for millions of nomadic, buffalo-like dranzers which mainly inhabited the western side of the continent.
In the year 2256, the Federation established an agricultural colony that expanded to cultivate two-thirds of its arable land, maintaining several hundred thousand kilometers of grain crops on the eastern plains and center of the continent. But the colonists soon discovered that the six-year life cycle of the dranzers resulted in 70-90% of their crops being periodically trampled.
In 2268, the Federation Agricultural Division assigned the starship USS Enterprise to resolve the crop situation. To protect the planet's ecology, Spock devised a method of rerouting the 200-kilometer-wide stampede into a circle to the west. (TOS audiobook: The Logistics of Stampede)
