50 Years Ago, This Was a
Wasteland

Almost
50 years ago, fried chicken tycoon David Bamberger used his fortune to purchase
5,500 acres of overgrazed land in the Texas Hill Country. Planting grasses to

its original habitat and boasts enormous biodiversity. Bamberger's model of
land stewardship is now being replicated across the region and he is considered
to be a visionary in land management and water conservation.

SPECIES INVASIONS: Water Hyacinth and Zebra Mussels

Water hyacinth (Eichhornia crassipes) is a perennial, free-floating aquatic weed, native to South America’s Amazon River, but carried overseas for ornamental use. Today the water hyacinth is considered to be the “world’s worst aquatic weed.” This aggressive, invasive species spreads rapidly over entire surfaces of lakes and ponds and can double its coverage in just two weeks. Yet its ability to withstand drastic fluctuations in flow rates, acidity and low nutrient levels makes it a viable and popular water-garden plant.

Since imported to North America in 1884, it has invaded the Columbia and Mississippi River Basins, two NWNL case-study watersheds. Also introduced into East Africa, it is present in three NWNL basins: those of the Omo, Nile and Mara Rivers. Recorded in Egypt as early as the 1890’s, water hyacinth became a “plague” in the late 1900’s. River control schemes, such as dams, barrages and irrigation canals have encouraged it…

If the red planet is sterile, a human presence there would create no moral or ethical dilemmas on this front. But if life does exist on Mars, human explorers could easily lead to the extinction of Martian life.
