Series Description: LAND BETWEEN TWO RIVERS: PART 2 examines four biomes present in Iowa and challenges students to consider issues surrounding their continued existence. The once expansive biomes are dwindling as development takes over. Biologists and other experts expound on the plant and animal life indigenous to each system and discuss approaches to protecting them.
Areas of woodlands are identified, and background information is provided on how they were formed. Experts on birds, mammals, and plants indigenous to woodlands talk about various species they have studied and observed. [42 minutes]
The theories of preservation and conservation as approaches to maintaining Iowa's woodlands are introduced. Proponents of each theory state their cases. [27 minutes]
A Prairie Conversation (#203)
The remaining acres of black fertile soil of the tallgrass prairies are insignificant compared to those of the inferior hill prairies of northeastern Iowa and the dry prairies near the Loess Hills along the Missouri River. In light of this, viewers are asked the question, "Is there a point below which it is not worth preserving Iowa's prairies?" [43 minutes]
Once considered inexhaustible wasteland, prairies are now known to be rife with plant and animal species. Students learn that the root systems of prairie plants may be as old as some of the stately oaks and other trees cherished by humans. [27 minutes]

Look to the Hills (#206)
The Loess Hills along the Missouri River corridor contain the largest tracts of undeveloped wilderness and greatest area of original prairie in Iowa. Wildlife is also very abundant there. Experts compare the hills' formation to similar hills found in China. [44 minutes]
