...cacti, yucca, ocotillo and the paloverde trees. "None of the native plants have fire adaptation. If they burn, they die," says Tom Van Devender, a senior research scientist at the Arizona-Sonora Desert Museum in Tucson. "If there is recurring fire, you get a conversion from desert to savannah grassland...
With a unique ecosystem of high-altitude forest (or shola) and grassland, India's western Ghats are home to several species of endangered flora and fauna. Notable among these is the Nilgiri tahr (Hemitragus hylocrius)?a primitive species of wild goat whose only viable population breeds in captivity at Munnar's Eravikulam National Park. But the real standout is the rare and beautiful Neelakurinji plant (Strobilanthus kunthianus), which grows in abundance in and around Munnar and is best enjoyed from Top Station. This exotic shrub's flowerings are few and far between?only once every 12 years, in fact...
Natsource arranged for Schrepel to pay a retail price of $17 a ton for carbon dioxide that is part of the natural chemistry of a 1,200-acre patch of Illinois grassland in a nature preserve. In return for part of that payment, the land's owner agreed not to burn, pave over or otherwise release that carbon dioxide. Schrepel wryly explained to her interns that buying the credits would help offset the carbon dioxide they emitted by, among other things, breathing...
...lost--at least not yet. Even as Wilson and others warn of an impending Armageddon, conservation groups and scientists are devising innovative strategies for preserving broad swaths of rain forest, grassland, tundra and coral reef before they are swallowed by the global village. All face the fundamental dilemma: how to balance man's economic urgency with nature's ecological vulnerability...
...meadows remain, the rest having been turned into farmland or housing developments. Last week the Danube rose 6 m above its normal levels in some places. With about half of Europe's population already living along rivers, it's doubtful that large tracts will be restored to grassland. More and better river management may be the only option. But Tockner says "those measures give people a false sense of security." He argues that a cost-benefit analysis would show that flood protection through natural meadows and forests would be more effective in the long run than apparent gains through agriculture...
