Nine out of 12 members of the National Park System Advisory Board resigned over frustrations that the Ryan Zinke, Interior Secretary, declined to meet with them or convene a single meeting last year, according to the Washington Post.

The nine departing members wrote a letter to Zinke, saying they have “stood by waiting for the chance to meet and continue the partnership … as prescribed by law.”

“We understand the complexity of transition but our requests to engage have been ignored and the matters on which we wanted to brief the new Department team are clearly not part of its agenda,” board chairman Tony Knowles wrote in the letter obtained by the Post.

“I wish the National Park System and Service well and will always be dedicated to their success.”
