THE TROPICAL RAIN FOREST Order #249...........$42.50

Rain forests are the climax vegetation in areas where a warm and equable
climate and abundant rainfall provide ideal conditions for plant growth. This set details
the stratification of the rain forest, the unique characteristics and adaptations of its life
forms, and representative plant and animal life of this biome. 20 slides and guide.

CONTENTS SAMPLE: 21698 The relatively shallow root systems of the trees are
apparently associated with excessive moisture that prevents aeration of the soil to any great
depth. The tendency of the trees to form above-ground supporting structures seems very logical,
considering the soil conditions and the shallow root systems. Both stilt roots and plank
buttresses, which are common, result from extra secondary growth on the top of the largest
lateral roots. They may radiate out from the tree as much as 10 m (30 ft.). Note how the
buttresses dwarf the people in the photo. Several of these highly developed lateral roots provide
support around the enormous trunk, which does not have the massive tap root so often found in
large trees of temperate forests.

TROPICAL RAIN FORESTS UNDER FIRE Video order #FV-1132V..........$59.95

by World Wildlife Fund and Garden Club of America

Details what we are losing as tropical rain forests are destroyed. These
mutilayered biological treasure houses are the source of some of our most widely used
and useful products--rubber, cocoa, quinine, curare--and wintering ground for many of our
favorite migratory birds. Yet tropical rain forests are being decimated, the web of
biological diversity is being sundered, and species are being lost before we are even able
to discover them. 116 frames, 32 page guide with many teaching resources. Video or
filmstrip. (Filmstrip order FS 1132F.....$49.95.)

CONTENT SAMPLE:

53. The superficial riches of the tropical rain forest have been discovered and
exploited,

54. but scientists estimate that only 15% of the plant and animal species in the rain
forest have been discovered.

55. What new medicines, new foods and new products could the rain forest yield?

56. But before we can understand what new products these unknown forests may
yield, we need to understand more about rain forest ecology.
