MEMORANDUM**

California state prisoner Michael S. Yellen appeals pro se the judgment dismissing his civil rights action pursuant to the “three strikes” filing limitation of the Prison Litigation Reform Act (“PLRA”), 28 U.S.C. § 1915(g). We have jurisdiction under 28 U.S.C. § 1291. We review both a challenge to the constitutionality of a statute and the district court’s interpretation of a statute de novo. Taylor v. Delatoore, 281 F.3d 844, 847 (9th Cir. 2002). We vacate and remand.

*447Yellen’s contention that two dismissals should not have counted as strikes under 28 U.S.C. § 1915(g), because they occurred prior to the enactment of the PLRA, is foreclosed by Rodriguez v. Cook, 169 F.3d 1176, 1181 (9th Cir. 1999).

As the third strike, the district court counted the Ninth Circuit appeal Yellen v. Olivarez, No. 96-16369, which was dismissed for failure to prosecute. However, failure to prosecute is not a ground for dismissal within the ambit of 28 U.S.C. § 1915(g). Accordingly, Yellen v. Olivarez, No. 96-16369 should not have been considered a strike. As the district court did not identify any other qualifying strikes, we vacate the dismissal of Yellen’s action and remand.

Appellees shall bear the costs on appeal.

VACATED and REMANDED.
