5. “Seas of Grass”
Broadcast 23 February 1984, this programme looks at a plant of which there are some 10,000 species and which covers over a quarter of vegetated land: the grasses. It is a plant that keeps growing despite continuous grazing — because a grass leaf grows at its base, which is permanently active. At such low levels, lizards prey on insects, praying mantis eat grasshoppers, spiders hunt anything they can and dung beetles clear up the mess. Termites are among the most successful: in the savannah of Brazil, there are more termite mounds per acre than anywhere else — and where they flourish, the anteater follows. At dawn on the Brazilian campo, many open-nesting birds are vulnerable to species such as the tegu. There are few trees because of little water and during the dry season, caiman and turtles vie for space in such pools as there are. 3,000 kilometres to the north, in Venezuela, the clay soil enables the llanos to hold flood water, and some creatures, such as the capybara, relish it. Further north still, on the North American prairie, the freezing temperature of minus 46°C means that few animals can survive it; the bison is one that can. The African plains have a greater variety and bigger concentration of grass-living animals than any other. This leads to a similar abundance of predators, and the Merle people ambush white-eared kob as they cross a river. Of the million animals that attempt the crossing over several days, some 5,000 are killed.
6. “The Baking Deserts”
Broadcast 1 March 1984, the next instalment explores the world of deserts. It begins in the largest, the Sahara, where the highest land temperatures have been recorded. Rock paintings depict creatures such as giraffes and antelopes, suggesting that at one point there was enough vegetation to support them. Now, such life has all but disappeared, with the exception of the cypress, whose roots find water deep underground. Since the night brings low temperatures, many of the creatures that live there are nocturnal. They include fennecs, geckos, jerboas and caracals. A scorpion is shown fighting a black widow spider. During the day, the desert belongs to the reptiles, which rely on the sun to warm their bodies. The Sonoran desert is home to the Gila monster, one of the two poisonous lizards. By mid-afternoon, it’s so hot that even reptiles must escape the sun’s rays. However, some birds have developed methods for keeping cool. The sandgrouse evaporates moisture by fluttering its throat, while the road runner also uses its tail as a parasol. Plants that are best adapted to the habitat are the creosote bush and cacti, of which the saguaro is one of the biggest. The nomadic Tuareg people cross the Sahara from one side to the other — but can’t do so unaided. They rely on the camel for transportation, as much as it needs them to periodically dig for water. Despite this, it is one of the best adapted desert animals: it can go without water for ten times as long as a man.
