Plabic (planar, bicolored) graphs were introduced by Postnikov in his work on the totally nonnegative Grassmannian. To each of these graphs, one can associate a link called a plabic link. Each plabic graph also has a quiver which is obtained by taking a dual graph with a certain orientation on the edges. I will present a closed formula for the HOMFLY polynomial of a plabic link in the case where the quiver of the plabic graph is an orientation of a forest.
