Chapter 10 Section 3 Questions By: Niall Martin, Cassidy McDonald, Claudia Noonan
What are rangelands? • Unfenced grasslands • Temperate or Tropical climates • Supply forage, or vegetation, for grazing and browsing animals. • 42% of the grassland is grazed on by cattle, sheep, and goats. What are pastures?? • Manage grasslands or enclosed meadows • Planted with domesticated grasses or other forage
What is Over grazing? • Plants are exposed to intensive grazing • Extended periods of time • Without sufficient recovery periods • Caused by livestock in poorly managed agricultural applications What Problems Arise? • Reduces grass cover • Exposes soil to erosion • Compacts the soil • Enhances invasion of foreign species cattle will not eat
What Problems arise from Under grazing? • Reduces the net primary productivity of grassland vegetation and grass cover What Are conservation easements? • Land trust groups will pay ranchers for deed restrictions that bar future owners from developing the land. • Pressure on government to prevent large scale development on fragile land
How can Rangelands be maintained sustainably? • Control the amount of cattle and how long they graze so the carrying capacity will not exceed. • Rotational grazing- confined in a fenced area for a short period of time and then moved. • Suppress to growth of invader plants and replanting of more useful plants - Burning, herbicide, trampling
