Final answer:
The limited space in the Parkland Region for flora and fauna is due to habitat fragmentation, land development, economic and political pressures, and the effects of climate change. Despite 11% of the Earth's land being protected, preserves often fail to represent all biomes or species, and management challenges limit their effectiveness. Conservation efforts must extend beyond preserves to include fragmented landscapes for better biodiversity protection.
Step-by-step explanation:
The limited amount of space for animals and plants in the Parkland Region is primarily due to a combination of factors including habitat fragmentation, land development, and political and economic pressures. Despite significant areas of land being designated as conservation preserves, they are often not large enough to protect all species, with only about 11% of Earth's land surface currently protected. This area falls short of including all biomes or adequately representing global biodiversity. Conservation challenges involve the establishment of sufficiently large preserves and ensuring their effective management, which is often limited by resource constraints. Climate change further exacerbates these issues by altering ecosystems and potentially reducing the effectiveness of current preserves.
