Dolphin Stadium has joined the “green movement” – with the help of Waste Management, which added automated recycling machines at the stadium and gave out tips for preserving the environment at the Dolphins' last home game of the season.

Now, StubHub is using the Dolphins’ first playoff game in seven years to help plant trees in the country’s national forests. For every ticket Dolphins-Baltimore Ravens ticket re-sold on StubHub.com (tickets are still available for the 1 p.m. Sunday game from $82 to $2,000), the online ticket marketplace will plant a tree in the National Forests of Florida. The company’s “Tickets for Trees” program will also plant one tree for every dollar donated to the National Forest Foundation in the name of the Dolphins.

The National Forests of Florida include nearly 1.2 million acres in the Apalachicola, Ocala and Osceola national forests. StubHub is donating trees in honor of each of the teams hosting playoff games through the postseason and to the Ocala National Forest for Super Bowl XLIII, which is being played in Tampa.

StubHub expects to plant tens of thousands of trees – the type will be determined by the National Forest Foundation, spokeswoman Joellen Ferrer said. She said several thousand will be planted in honor of the Dolphins based on tickets sold and donations made. The company will not release specific figures until after the Super Bowl, she said.

“We are excited to involve our fans in this campaign to help restore the country’s National Forests,” Ferrer said. “Assuming all goes well, we plan to expand this program and continue StubHub Tickets for Trees based around other events.”
