MEMORANDUM **

Steven Emory Butcher was convicted of two counts of willfully and without authority setting fire to federal land, in violation of 18 U.S.C. § 1855, as well as three misdemeanor offenses. The convictions stem from wildfires Butcher started in Los Padres National Forest in 2002 and 2006. We have jurisdiction under 28 U.S.C. § 1291 and 18 U.S.C. § 3742, and we affirm his convictions and sentence. The parties are familiar with the facts of this case, so we repeat them here only as necessary.

Butcher argues some of his convictions overlap to such a degree that they violate his rights under the Fifth Amendment’s Double Jeopardy Clause. Because he raises this issue for the first time on appeal, we review for plain error. United States v. Schales, 546 F.3d 965, 977 (9th Cir. 2008). Contrary to Butcher’s contention, 18 U.S.C. § 1855 and 36 C.F.R. § 261.52(a) are separate and distinct offenses because each “requires proof of a fact which the other does not.” Blockburger v. United States, 284 U.S. 299, 304, 52 S.Ct. 180, 76 L.Ed. 306 (1932). Section 1855 requires proof that a defendant willfully started a fire; § 261.52(a) does not. United States v. Velte, 331 F.3d 673, 677 n. 1 (9th Cir. 2003). Section 261.52(a) requires proof that a defendant violated a specific Forest Service prohibition against setting fires; § 1855 does not. Id. at 677-78. Butcher’s argument that § 1855 is a lesser-included offense of 36 C.F.R. § 261.5(e) is equally unavailing. Section *629 1855 requires proof of an element not found in § 261.5(e), namely that a fire be started “without authority.” 1 We find no error, let alone plain error, in Butcher’s multiple convictions.

We review the district court’s determination of the amount of loss for clear error. United States v. Santos, 527 F.3d 1003, 1006 (9th Cir. 2008). The district court determined that Butcher was responsible for $228,000 in losses, one of several alternative amounts proposed by Butcher himself. We are not persuaded by Butcher’s argument that the district court erred in including fire suppression costs in the loss calculation. There was sufficient evidence in the record to conclude that Butcher knew or should have known that fire suppression expenditures were a reasonably foreseeable result of his actions. See United States v. Warr, 530 F.3d 1152, 1158-59 (9th Cir. 2008).

Butcher’s contention that the district court impermissibly enhanced his sentence based on a loss amount not determined by the jury is squarely foreclosed. See United States v. Hickey, 580 F.3d 922, 932 (9th Cir. 2009). The same is true of Butcher’s as-applied Sixth Amendment challenge to his sentence. See United States v. Treadwell, 593 F.3d 990, 1016-18 (9th Cir. 2010).

Finally, we reject Butcher’s argument that the district court erred by including fire suppression costs in the restitution order. The Forest Service incurred the suppression costs as a direct result of Butcher’s offenses. The causal chain does “not extend so far, in terms of the facts or the time span, as to become unreasonable.” United States v. Gamma Tech Indus., Inc., 265 F.3d 917, 928 (9th Cir. 2001).

AFFIRMED.
