Final answer:
Researchers found that habitat loss due to residential development and forestry contributed to the decline of red-cockaded woodpeckers. Landowners were hesitant to participate in recovery efforts due to potential restrictions on their property. The 'safe harbor' program was implemented to alleviate these concerns and has successfully enrolled over 1.5 million hectares in habitat restoration.
Step-by-step explanation:
Researchers who studied the decline of red-cockaded woodpeckers found that residential development and short-rotation forestry resulted in the elimination of their habitat. Many landowners cut down stands of young pine trees to prevent the woodpeckers from colonizing their property, fearing restrictions on the use of their land.
To address this issue, the federal government implemented a program called 'safe harbor' that assures landowners they will not face additional regulatory restrictions for engaging in activities that benefit endangered species like the red-cockaded woodpeckers. This program has led to the enrollment of over 1.5 million hectares in habitat restoration efforts.
