Question

due to the chorotega regions accessibility, various types of forested areas were converted to cattle pasture as rising international meat prices drove a cattle ranching boom in the 1960s and 1970s. juan pablo arroyo - mora and colleagues used historical aerial photography and remote sensing data to track fragmentation metrics across different land - use capability classes (categories that indicate possible uses of forest land). one such metric, edge density, can be used to indicate the regularity of forest patch sizes, with decreases in edge density suggesting a trend towards uninterrupted forest patches with more regular shapes. the team found a range of edge density levels, from lows of around 80 meters per hectare or less in the 1960s and 1970s for all classes, to a high in 1986 of approximately - which choice most effectively uses data from the graph to complete the assertion? a) 140 for class vii. b) 160 for class i - iv. c) 60 for class vii. d) 50 for class vi. edge density (meters/hectare)

Explanation:

Step1: Locate the data for the 1960s - 1970s

Look at the edge - density graph for the years 1960 and 1979.

Step2: Identify the edge - density values for each class

For Class I - IV, the edge - density is around 140 meters per hectare in the 1960s - 1970s.

Answer:

A. 140 for Class I - IV
