COLLIER COUNTY, Fla.- The number of hatched sea turtle nests in Collier County is skyrocketing.

Numbers released by the county this week show Collier County has seen 143 hatched nests so far. Compare that to the 73 hatched nests last year.

County environmentalists said the increase is because of conservation efforts over the past 30 years.
