What is likely to be the greatest challenge facing the zoned reserve systems of Costa Rica?

The aspect of conservation ecology concerned with returning degraded ecosystems (as nearly as possible) to their natural state is

The International Union for the Conservation of Nature (IUCN) monitors changes in global biodiversity. It is a network that is composed of both government and nongovernment organizations. The IUCN collects data on the status of the natural world and uses these data to make conservation and sustainable development recommendations. One widely recognized metric for evaluating organismal conservation is the IUCN Red List. This list uses several criteria to calculate the survival probability of organisms throughout the world. The aggregate Red List survival probability for birds, mammals, amphibians, corals, and cycads in different geographic regions is summarized in the table. Table 1.

One way in which distributions of populations and species have been responding to climate change is by shifting

As the climate warms, the population ranges of organisms may shift to different areas that are cooler. However, as humans continue to fragment large tracts of land, species will face increasing challenges in adapting their ranges to new climates. For example, movement corridors may not be able to be built if the amount of land needed for a species' range is fragmented due to cities and roads. One alternative to creating movement corridors is called managed relocation. This requires physically moving species to cooler climates. -What is a disadvantage of using managed relocation?
