Opinion by Judge SILVERMAN; Dissent by Judge NOONAN

Does a logger’s refusal to desist logging operations on Forest Service land, after a *1299 Forest Service Law Enforcement Officer ordered him to do so at the behest of the Forest Service representative authorized to shutdown the logging operation, constitute “interfering with any forest officer engaged in or on account of the performance of his official duties in the protection, improvement, or administration of the National Forest System” under 36 C.F.R. § 261.3 (a)? We hold that it does, and we affirm.

I. BACKGROUND

The evidence at trial established the following facts: Eel River Saw Mills entered into two contracts with the U.S. Forest Service for the purchase of timber in the Six Rivers National Forest. The events material to this case concern the sale of timber from the Crabtree parcel. Eel River Saw Mills hired appellant Willfong, an independent logging contractor, to perform the logging operations at the Crabtree site. The Forest Service designated Leo-nora Crippa as its sale administrator for the project to monitor the performance of the contract. The Forest Service delegated to Crippa the contractual authority to, among other things, issue an oral order to temporarily shutdown logging operations to prevent human or environmental injury.

Believing Willfong and his crew to be in breach of the logging contract at the site of the other sale (Tub Springs), and concerned about the skidding practices and the resulting damage to the area at Crab-tree, Crippa notified Eel River Saw Mills on July 2, 1998, that skidding at the Crab-tree sale was shutdown. The next day, Crippa went to Crabtree and observed that the logging operations were still going on. Crippa told Willfong that the skidding at Crabtree was supposed to have stopped and had to stop. Willfong refused to stop the skidding.

Uncomfortable with the increasingly tense situation, Crippa left the area, decided that all operations at Crabtree must be suspended, and contacted U.S. Forest Service Law Enforcement Officer John Allen-dorf. Crippa told Allendorf that she had issued a suspension order on a timber sale and that the order was being disobeyed. Crippa requested Allendorfs assistance in gaining compliance with the shutdown order. Allendorf knew that Crippa had the authority to issue a shutdown order.

Officer Allendorf followed Crippa to Crabtree, then went down to the sale area alone. He encountered Willfong and heard the sound of logging equipment. Allendorf told Willfong that an oral shutdown had been issued and that he would have to suspend operations until the matter of the suspension was resolved. Allen-dorf continued to try to secure Willfong’s voluntary cooperation in ceasing operations, but Willfong stated that he would not shut down. Allendorf warned Willfong that he could be arrested, but Willfong still refused to shut down his operation. Allen-dorf offered to cite-and-release him if he would cooperate in shutting down. Will-fong refused. Allendorf then placed Will-fong under arrest. After being arrested, Willfong encouraged his crew to keep on with their logging operation, saying words to the effect of “I don’t want you guys to shut down. Just keep working.”

Willfong was charged with two violations: Threatening, resisting, intimidating, or interfering with a forest officer, in violation of 36 C.F.R. § 261.3 (a); and unauthorized timber cutting, in violation of 36 *1300 C.F.R. § 261.6 (a). At trial before U.S. Magistrate Judge Craig M. Kellison, Will-fong was acquitted of unauthorized timber cutting, but found guilty of interfering with a Forest Service officer. He was placed on probation and fined $250.00. Willfong appealed his conviction to U.S. District Judge William B. Shubb, who affirmed Judge Kellison’s decision.

II. JURISDICTION

We have jurisdiction pursuant to 28 U.S.C. §§ 1291 and 1294. We review a trial court’s interpretation of a regulation de novo. United States v. Hoff, 22 F.3d 222, 223 (9th Cir.1994). Because Willfong appeals his conviction, this court views the record in the light most favorable to the Government to determine whether a rational trier of fact could have found the elements of the crime beyond a reasonable doubt. United States v. Arbo, 691 F.2d 862, 866 (9th Cir.1982).

III. ANALYSIS

A. Allendorf s Order Took Place in the Performance of His Official Duties

36 C.F.R. § 261.3 (a) provides:

Willfong contends that he did not violate section 261.3(a) because, he says, the forest officer’s order was unlawful. We disagree.

On appeal, after a finder of fact has convicted the defendant, we must view the evidence in the light most favorable to the prosecution. E.g., United States v. Crawford, 239 F.3d 1086, 1092 (9th Cir. 2001). The evidence supports a finding that Allendorf was performing his duties in the administration of the National Forest at the time Willfong allegedly interfered with him. For purposes of 36 C.F.R. § 261.3 (a), a forest officer is performing an “official duty” when the officer is on duty and performing an act that contributes to the protection, improvement, or administration of the National Forest. United States v. Ryberg, 43 F.3d 1332, 1334 (9th Cir.1995); 36 C.F.R. § 261.3 (a). Clearly, Allendorf was on duty, performing his duties, and acting in his official capacity at all material times. He was not off on a “frolic of his own.” Ryberg, 43 F.3d at 1334 . Allendorf carried out the directions of an official seeking to enforce the provisions of the Forest Service’s logging contract. Since the Forest Service designated Crippa as the administrator of the contract, and Crippa sought Allendorfs help in enforcing the shutdown order, Willfong “cannot successfully argue that this kind of administrative deployment of Forest Service officers was not germane to the protective mission of the Forest Service.” Id.

Willfong also argues that he could not have interfered with Allendorf because, he contends, Allendorf was attempting to enforce an invalid shutdown order. This argument fails for two reasons. In the first place, the evidence presented at trial indisputably established that Crippa had the authority to suspend the logging operations under the terms of the contract and the authority delegated to her by the Forest Service. Secondly, even if Crippa lacked such authority, Willfong nevertheless had no right to interfere with Allen-dorf. So long as Allendorf was performing his official duties in the administration of *1301 the Forest System, 36 C.F.R. § 261.3 (a) prohibits anyone from interfering with those duties. By way of analogy, a person does not have the right to resist arrest even if the charges are false or the arrest unlawful. United States v. Cunningham, 509 F.2d 961 (D.C.Cir.1975). It is undisputed that Allendorf relied in good faith on the validity of Crippa’s shutdown order when he sought to enforce it. It was Crippa’s job, not Allendorfs, to determine whether a temporary shut down order should be issued under the provisions of the administration contract. If Willfong disagreed with Crippa’s order, he had the right to try to get it rectified. He did not have the right to interfere with the officer’s enforcement of it.

B. Willfong’s Refusal to Shut Down Crabtree Constitutes “Interference” under 36 C.F.R. § 261.3 (a)

Willfong contends that the failure to obey a forest officer’s order does not constitute “interference” with the officer as a matter of law. We disagree.

Courts have not expressly addressed what constitutes “interference” under 36 C.F.R. § 261.3 (a). Without prior interpretation, this court should apply the common meaning of a word. See Hoff, 22 F.3d at 223 . To “interfere” is to “oppose, intervene, hinder, or prevent.” WEBSTER’S NEW WORLD DICTIONARY 704 (3d College ed.1998). “ ‘[Ijnterfere’ has such a clear, specific and well-known meaning as not to require more than” the use of the word itself in a criminal statute. United States v. Gwyther, 431 F.2d 1142 , 1144 n. 2 (9th Cir.1970). The plain meaning of “interfere” also comports with the purpose of the regulation, which is to regulate “the use of the National Forests and to preserve them from destruction.” Ryberg, 43 F.3d at 1334 ; see also 16 U.S.C. § 551 .

The lower courts’ determination that Willfong’s actions constituted interference is consistent with the plain meaning of the word. In failing to shut down the logging operation when ordered to do so by Allen-dorf, Willfong clearly hindered Allendorfs ability to perform his official duty. At the time of Allendorfs shut down order, Will-fong and his crew actively were logging trees. Allendorfs ability to execute the shut down order depended upon Willfong and his crew taking affirmative steps to cease operations. Willfong interfered with Allendorf in refusing to stop what he and his crew were doing. Willfong did not merely do nothing. He refused to stop doing something — in this case, to stop his logging in the face of an officer’s official attempt to stop it.

This situation is similar to what occurred in United States v. Arbo, 691 F.2d 862 (9th Cir.1982). In Arbo , the defendant refused to allow a Forest Ranger and a Mineral Assistant to make a compliance inspection of his mining operation in the Shasta-Trinity National Forest and had them escorted away from the site. We held that there was sufficient evidence to support a conviction for interference with a forest officer.

Willfong contends that his refusal to abide by Allendorfs order did not constitute. “interference” because he did not use any physical force. Willfong relies primarily on District of Columbia v. Little, 339 U.S. 1 , 70 S.Ct. 468 , 94 L.Ed. 599 (1950), in which the Supreme Court held that a woman who refused to unlock her door and permit a health inspection of her home, without a warrant, was not interfering under a statute that made it illegal to interfere with health inspections. The essence of Little is this:

Id. at 6-7 , 70 S.Ct. 468 .

Little does little for Willfong. Little makes it clear that force or threatened force is not an essential ingredient of interference. 839 U.S. at 6, 70 S.Ct. 468 . Additionally, unlike Mrs. Little, Willfong was not asserting a significant constitutional right or merely remonstrating or voicing criticism. Instead, he affirmatively refused to discontinue logging on Forest Service land when ordered to do so by a forest officer acting under color of a shut down order. It is self-evident that Will-fong’s refusal to shut down Crabtree when ordered to do so interfered with Allen-dorf s attempt to shut it down.

Willfong’s assertion that force is an element of “interference” under 36 C.F.R. § 261.3 (a) is baseless. Neither the enabling statute, 16 U.S.C. § 551 , nor the regulation itself makes any mention of force or threatened force as a requirement for a violation of 36 C.F.R. § 261.3 (a). In fact, the regulations make clear that force is not a required element of interference. The regulation under which Willfong was convicted, 36 C.F.R. § 261.3 (a), falls under Title 36, Chapter II, Part 261, Subpart A, which lists the general prohibitions in the National Forest System. Within that Sub-part, one provision — 36 C.F.R. § 261 .1— defines the scope of all of the prohibitions in that Subpart, including those in 36 C.F.R. § 261.3 (a). Section 261.1 clearly indicates that the prohibitions covered in the regulations are broad. It states that the prohibitions apply, except as otherwise provided, when “[a]n act or omission occurs in the National Forest System or on a National Forest System road or trail.” 36 C.F.R. § 261.1 (a)(1) (emphasis added). When § 261.3(a) is read in light of § 261.1(a)(1), the definition of “interference” under the regulations applies to any act or omission that interferes with an officer’s official duties. Willfong acted to interfere with the officer’s shut down order by refusing to stop the logging. Whether Willfong’s refusal to obey the shut down order is classified as an act or omission, however, it was prohibited by the regulations.

In United States v. Bassil, 932 F.2d 342 (4th Cir.1991), the court held that force was not an element of interference where the statute stated that one committed a felony if he “assaults, resists, opposes, impedes, intimidates or interferes with ... any officer or employee of any penal or correctional institution.” 932 F.2d at 345 . The court stated: “We decline to usurp the legislative function by reading a requirement of forcible resistance [into the statute].” Id. The court continued by stating that “[i]t is quite possible ... to impede or interfere with an officer without actually using force.” Id.

Other interference cases decided after Little also make clear that force is not a required element of interference. In United States v. Bass, 82 F.3d 811 (8th *1303 Cir.1996), for example, the court held that a driver’s refusal to obey a National Park Service Ranger’s order to “stand still” at the rear of the vehicle — by walking away three times and kicking the door to his vehicle shut — constituted interference with the Ranger’s duties. 82 F.3d at 811-12 . See also State v. Boone, 243 Ga. 416 , 254 S.E.2d 367 (1979), cert. denied, 444 U.S. 898 , 100 S.Ct. 206 , 62 L.Ed.2d 133 (1979) (refusal to obey order to vacate building constitutes interference); Ratliff v. State, 133 Ga.App. 256 , 211 S.E.2d 192 (1974) (refusal to obey order to stop attempting to enter a premises being searched constitutes interference); City of Chicago v. Lynd, 47 Ill.2d 205 , 265 N.E.2d 116 (1970), cert. denied, 402 U.S. 923 , 91 S.Ct. 1383 , 28 L.Ed.2d 662 (1971) (refusal to obey order to clear the street constitutes interference); State v. Manning, 146 N.J.Super. 589 , 370 A.2d 499 (App.Div.1977) (refusal to obey order to re-enter vehicle constitutes interference); Township of East Brunswick v. Malfitano, 108 N.J.Super. 244 , 260 A.2d 862 (App.Div.1970) (refusal to obey order to provide one’s name and address constitutes interference).

It has been argued that the doctrine of ejusdem generis should apply to construe 36 C.F.R. § 261.3 (a). Under ejusdem gen-eris, where general words follow specific words in statutory enumeration, the general words are construed to embrace only objects similar in nature to those objects enumerated by the preceding specific words. See Leslie Salt Co. v. United States, 896 F.2d 354 , 359 n. 8 (9th Cir.1990), ce rt. denied, 498 U.S. 1126 , 111 S.Ct. 1089 , 112 L.Ed.2d 1194 (1991); see also 2A SUTHERLAND STATUTORY CONSTRUCTION § 47.17 at 273-74 (6th ed.2000). The argument goes as follows: “Interference” is a general term at the end of the specific series, and the prior specific terms in this series are “threatening,” “resisting,” and “intimidating”; therefore, interference is limited to forcible actions similar in nature to threatening, resisting or intimidating.

Ejusdem generis does not apply in this case. The Ninth Circuit in United States v. Hoff, 22 F.3d 222 (9th Cir.1993) examined the relationship of the terms “threatening,” “resisting,” “intimidating,” and “interfering” in section 261.3(a), and held that each offense is independent from the others. In Hoff , the defendant was convicted under 36 C.F.R. § 261.3 (a) of intimidating a forest officer by yelling at her when she issued a ticket and later ordering a dog to “go get ’em.” 22 F.3d at 223 . The defendant argued on appeal that the magistrate judge erred by focusing exclusively on “intimidating” rather than on “threatening” or “interfering.” Id. We stated that proof of any one of the acts in section 261.3(a) could support a conviction because the regulation is “plainly stated in the disjunctive” and prohibits “[threatening, resisting, intimidating, or interfering” with a forest officer. Id. To read the regulation otherwise, the court stated, would be a “patent misreading of Section 261.3(a).” Id. This court indicated recently that Hoff came to the obvious and correct result. See United States v. Taylor, 258 F.3d 1065, 1068 (9th Cir.2001) (saying that “[n]ot surprisingly,” the Hoff court concluded that proof on any one of the acts in § 261.3(a) supported a conviction.)

Hoff is consistent with the canons of statutory construction. “The rule of ejus-dem generis, while firmly established, is only an instrumentality for ascertaining the correct meaning of words when there is uncertainty.” Gooch v. United States, 297 U.S. 124, 128 , 56 S.Ct. 395 , 80 L.Ed. 522 (1936); Federal Trade Comm’n v. *1304 MTK Mktg., Inc., 149 F.3d 1036, 1040 (9th Cir.1998), cert. denied, 525 U.S. 1139 , 119 S.Ct. 1028 , 143 L.Ed.2d 38 (1999); Leslie Salt Co., 896 F.2d at 359 . The meaning of the term “interference” is clear and there is no uncertainty. In addition, ejusdem generis cannot “be use to defeat the obvious purpose of legislation.” Gooch, 297 U.S. at 128 , 56 S.Ct. 395 ; see also United States v. Alpers, 338 U.S. 680, 683 , 70 S.Ct. 352 , 94 L.Ed. 457 (1950) (refusing to apply ejusdem generis on the grounds that it would defeat the purpose of the legislation). To apply ejusdem generis here would defeat the broad purpose of the regulation, which is to regulate the use of the national forests and to preserve them from destruction. Ryberg, 43 F.3d at 1334 . Finally, “while penal statutes are narrowly construed, this does not require rejection of that sense of the words which best harmonizes with the context and the end in view.” Gooch, 297 U.S. at 128 , 56 S.Ct. 395 .

The regulation, 36 C.F.R. § 261.3 (a), does not refer to force and we decline to read the rule to require that physical force be used to interfere with an officer’s duties. By actively refusing to stop logging, Willfong interfered with the forest officer’s ability to enforce a shut down order at Crabtree. Viewed in the light most favorable to the prosecution, a reasonable trier of fact could find that Will-fong interfered with Allendorfs official duties. See Arbo, 691 F.2d at 866 .

IV. CONCLUSION

The judgment of the district court is AFFIRMED.
