Final answer:
The two important focuses to prevent species loss involve improving and expanding protected areas and embracing an ecosystem-based conservation strategy, supplemented by recognizing and managing ecological processes and utilizing tools like the IUCN Red List for conservation guidance.
Step-by-step explanation:
The two important focuses to prevent species loss are: the establishment and maintenance of protected areas, and adopting a broad conservation strategy that addresses threats to ecosystems and species. To achieve effective protection for endangered species, conservation must identify and protect critical habitats, often necessitating the increase in size or quality of preserves, or better targeting with biodiversity protection in mind.
Furthermore, understanding ecological processes and integrating modern technologies is essential to catalog species and manage habitats. The IUCN Red List serves as a crucial tool for guiding conservation on the ground. However, attention should also be paid to ecosystems that are maintained by natural disturbances, replicating these disturbances where necessary.
