Q.54 Migratory species pose special preservation challenges, because
1. they are endemic, they are especially susceptible to habitat destruction.
2. their conservation may require international cooperation, when they require habitats in different countries.
3. they are often prone, population number, decline during their long migratory journeys.
4. they reside in biodiversity hot spots, that are most susceptible to habitat degradation.
Migratory Species Conservation Challenges: Q.54 Correct Answer Explained
Migratory species face unique hurdles in preservation due to their wide-ranging movements across borders. The primary challenge stems from the need for coordinated efforts across multiple nations.
Correct Answer
Option 2 is correct: “their conservation may require international cooperation, when they require habitats in different countries.”
Option Explanations
-
Option 1 incorrect: Migratory species travel widely and are rarely endemic, which means restricted to one area; they aren’t especially tied to habitat destruction like stationary endemics.
-
Option 2 correct: These species use breeding, wintering, and stopover sites often spanning countries, demanding treaties like CMS for shared protection.
-
Option 3 incorrect: While journeys pose risks like exhaustion or predation, this doesn’t uniquely challenge preservation compared to cross-border coordination.
-
Option 4 incorrect: They don’t exclusively reside in biodiversity hotspots; many use ordinary habitats, so degradation there isn’t the special issue.
Key Conservation Insights
International agreements address stopover site protection and flyway management. Population declines from habitat loss hit 44% of monitored species, underscoring urgency.
Exam Strategy
Link “special challenges” to jurisdiction issues over general threats. Practice with CMS examples for ecology questions.
