BOSTON (CBS) – Boston Bruins defenseman Andrew Ference has the reputation for being a big-time environmentalist.

Now he’s putting his money where his mouth is, though he’ll need some help from Bruins forward Tyler Seguin.

For the shortened 2013 season, Ference has pledged to plant 50 trees for every goal Seguin scores.

It all started shortly after Ference helped break the news the NHL and NHLPA reached a tentative agreement to end the lockout. Early Sunday morning, Ference jokingly tweeted “For every NHL pass, a tree will be planted. Every NHL goal, a solar panel will be installed. Wait… what? Those proposals didn’t get in?!?”

That inspired the Bruins Blog Stanley Cup Of Chowder to reach out to the B’s blue liner, and offer up a tree donation of their own.

“Okay, @Ferknuckle. We’re ready for the season. For every goal you score, we’ll plant 50 trees. plantabillion.org Get going. #Bruins,” the blog tweeted to Ference.

But with Ference only having 33 goals to his name over his 12-year-career, he decided to up the offer and go with a teammate that puts the puck in the back of the net a little more frequently.

“@cupofchowdah You guys are awesome! OK, I’ll match that offer but I’ve seen my career stats and will plant for @tylerseguin92 goals instead,” he tweeted back.

The trees will be planted through the “Plant a Billion Trees” campaign, a restoration initiative launched by The Nature Conservancy in 2008 to restore Brazil’s Atlantic Forest.

Seguin was Boston’s leading scorer last season with 29 goals in 81 games played. He’ll likely only have 48 games to work with this season, but given he netted 25 goals in 29 games while playing in the Swiss League, Ference may be planting an entire forest come the summer.
