Donald Trump is showing off his green fingers.

The White House today announced that President Trump has donated his salary from the first quarter—or $78,333.32—to the National Park Service. The president had previously said that he would be giving up his entire $400,000 annual salary to a charitable cause and press secretary Sean Spicer presented Ryan Zinke, the newly minted Interior Secretary, with a check during a press briefing today.

Zinke, whose department oversees the National Park Service, said that he was “thrilled” by the donation, which he said would be put to use to improve the infrastructure on historic battle sites. The Trump administration’s proposed budget would cut 12% from the annual budget of the Department of the Interior, which manages 530 million acres of land, or about 20% of all U.S. territory.

Trump has some way to go if he wants to catch up with America’s bigger nature philanthropists. For instance, asset manager David Rubenstein last year donated $18.5 million in an effort to help restore the Lincoln Memorial. That was Rubenstein’s fourth major donation to the National Park Service .

The National Park Service has been a favorite topic of Trump since he took office. He reportedly called the agency’s acting director the day after his inauguration to see if the agency had photos that would prove the media lied about the size of the crowd on January 20th.
