What is the meaning the meaning of the phrase “economically efficient treatments” in Table 1 of the ROD?
Economic efficiency requires the greatest returns per dollar spent. More formally, it requires the greatest output of desired goods and services from a given amount of input.

If you simply say it is acres treated, the economically efficient alternative for managing in an Home Range Core Area (HRCA) might be the same as that in a threat zone. So, obviously you need to consider habitat one of your desired outputs as well.
