In the 1950s Torreya taxifolia, a type of evergreen tree once very common in the state of Florida, started to die out. No one is sure exactly what caused the decline, but chances are good that if nothing is done, Torreya will soon become extinct. Experts are considering three ways to address the decline of Torreya. The first option is to reestablish Torreya in the same location in which it thrived for thousands of years. Torreya used to be found in abundance in the northern part of Florida, which has a specific microclimate. A microclimate exists when weather conditions inside a relatively small area differ from the region of which that area is a part. Northern Florida's microclimate is very favorable to Torreya's growth. This microclimate is wetter and cooler than the surrounding region's relatively dry, warm climate. Scientists have been working to plant Torreya seeds in the coolest, dampest areas of the microclimate. The second option is to move Torreya to an entirely different location, far from its Florida microclimate. Torreya seeds and saplings have been successfully planted and grown in forests further north, where the temperature is significantly cooler. Some scientists believe that Torreya probably thrived in areas much further north in the distant past, so by relocating it now, in a process known as assisted migration, humans would simply be helping Torreya return to an environment that is more suited to its survival. The third option is to preserve Torreya in research centers. Seeds and saplings can be moved from the wild and preserved in a closely monitored environment where it will be easier for scientists both to protect the species and to conduct research on Torreya. This research can then be used to ensure the continued survival of the species.
The article discusses the recent decline in Torreya taxifolia population, and outlines three solutions that can address the risk of extinction. The professor in the lecture, however, opined that none of the three solutions being proffered is sufficient. She refutes each of the solution raised in the passage.
First, the passage states that establishing Torreya taxifolia trees in areas where it has previously flourished will be a good solution. The professor condemned this point noting that all the areas are now dry due to the effect of either global warming, or wetland drains. Hence, it would be an unlikely solution.
Furthermore, the passage states that moving Torreya plants to an entirely new location is a possible solution. The professor refutes this idea by stating that assisted migration often results to unforeseen outcomes. She cited the scenario that occurred when the black locust tree was migrated to a new area. Trees and animals in the new area were negatively impacted by the introduction of a foreign plant.
Finally, the passage claimed that storing Torreya taxifolia in research centres could help prevent population decline. However, the professor negated this claim by saying that research centres are not big enough to accommodate the large and diverse population required for the plant to prevent disease. She further stated that this diverse population can only be catered for on the field.
