Final answer:
A significant portion of Tesso Nilo Park has been degraded, and the responsibility for protection lies with the Indonesian government, although the park faces challenges similar to other protected areas worldwide, where local demands and insufficient funding complicate conservation efforts.
Step-by-step explanation:
Tesso Nilo Park, while intended to be a large area of high-quality forest, has unfortunately experienced significant degradation. With the growing demand for timber, areas like Tesso Nilo are under constant threat, and the ideal scenario of the entire park being of high quality no longer holds true. As such, the answer closest to the reality would likely be that a significant portion of the park has been degraded, and the responsibility for protecting these areas falls on the Indonesian government. The enforcement challenges combined with the demand for resources such as firewood mean that not all areas are adequately protected, which is the situation in many conservation areas around the world. In Africa, for instance, national parks and wildlife preserves are created to protect valuable ecosystems, but similar issues of funding and human demands hamper conservation efforts. Indigenous co-management, such as seen in the Kaa-lya del Gran Chaco National Park in Bolivia, offers a model where local communities are involved in the management and protection of these areas, combining traditional knowledge with conservation goals.
