In this case we are presented with a question of first impression: Who bears the burden of proof when a defendant is charged with occupation of Forest Service land in violation of 36 C.F.R. §§ 261.10(b) and (k)? Must the prosecution prove that the defendant does not have individual aboriginal title, or is the claim an affirmative defense? We hold that the occupant claiming individual aboriginal title bears the burden of demonstrating such title as an affirmative defense. Applying that standard, we conclude that the defendant in this case failed to meet this burden, and we affirm the judgment of the district court upholding the defendant’s convictions.
I
Congress has charged the Secretary of Agriculture with “regulating] the[ ] occupancy and use” of the national forests by “rules and regulations.” 16 U.S.C. § 551. Any person violating such regulations may be tried before a magistrate judge and, if convicted, punished. Id. Under the Secretary’s regulations, no one may “possess[] ... occupy[ ], or otherwise us[e] National Forest System lands for residential purposes without a special-use authorization, or as otherwise authorized by Federal law or regulation.” 36 C.F.R. § 261.10(b). Section 261.10(k) similarly prohibits the “[u]se or occupancy of National Forest System land or facilities without special-use authorization when such authorization is required.”
There are effectively three ways that a claimant may be authorized to occupy national forest lands. First, a claimant may receive special-use authorization.
See
36 C.F.R. §§ 251.50, 251.52, 251.55. Second, she may claim authorization under the Forest Allotment Act, which permits Indians who are “not entitled to an allotment on any existing Indian reservation, or for whose tribe no reservation has been provided” to apply for an allotment. 25 U.S.C. § 337. The Secretary of the Interi- or may grant such allotment if the Secretary of Agriculture finds that the land is more valuable for agricultural or grazing purposes than for the timber.
Id.; see
43 C.F.R. §§ 2533.1, 2533.2. Third, she may claim individual aboriginal title to the land under the authority of the Supreme Court’s decision in
Cramer v. United States,
The Karuk people have occupied the Oak Bottom area of the Klamath National Forest in northern California from time immemorial. Karen Lowry, a Karuk Indi *1196 an, has resided on property located in the Oak Bottom area since approximately 1983. Lowry has not received a special-use authorization, nor has the Secretary of Interior granted Lowry an Indian allotment of land on this site. Oak Bottom encompasses a large area, including a Forest Service campground and work center, a 6.5 acre parcel known as Indian Allotment 280, and Lowry’s current residence, comprising about five acres. Indian Allotment 280, which is approximately fifty yards from Lowry’s residence, was granted to Oak Bottom Jack, one of Lowry’s relatives, and has passed to relatives other than Lowry. Lowry’s great-great-grandfather, Nupas, resided in the Oak Bottom area at least until 1900. Her great-great-grandmother, Mahkhawa’da, resided in a two-story log cabin located on the property now occupied by Lowry. The dates of Mahkhawa’da’s residence are unclear, but it appears that she was forced off the property by white miners at some point in the early 1900s. Mahkhawa’da later returned to the property after the miners left.
Lowry’s paternal grandmother, Bessie Tripp, was born in the area in the 1870s. Bessie was not raised on the land currently occupied by Lowry, but in a “house up at the upper end.” Bessie left the area to attend school and subsequently got married, though she returned on the weekends and during some summers. In 1926, Bessie took up permanent residence on Indian Allotment 280. Lowry resided with Bessie on Indian Allotment 280 until Lowry was eleven years old, when she was placed in foster care. Lowry occasionally returned to Oak Bottom to visit Bessie, although Lowry did not take up residence on the property she currently occupies until about April 1983, after Bessie’s death on December 6,1982.
In the late 1980s, the Forest Service accused Lowry of trespassing on Forest Service lands and encouraged her to obtain an Indian allotment for the land she occupied. She applied for an allotment in 1987. 1 On July 13, 1990, a Forest Service Supervisor determined that the land was not available for allotment because of its location within the Wild and Scenic River corridor of the Salmon River. The Supervisor also noted several other reasons that an allotment could not be granted, including Lowry’s statutory ineligibility and her failure to substantiate the agricultural uses of the land. When Lowry requested that the Supervisor permit her to reopen the proceedings, the Supervisor refused, citing the lack of any new information that would result in issuance of the allotment. California Indian Legal Services sent the Supervisor a “Notice of Appeal” on Lowry’s behalf, which the Supervisor denied because the governing regulations did not permit an administrative appeal in Lowry’s case. Lowry sought no further relief.
On August 8, 2003, the government charged Lowry with occupancy of Forest Service land in violation of 36 C.F.R. §§ 261.10(b) and (k).
2
Prior to trial, the government filed a motion in limine to exclude evidence that the government’s denial of Lowry’s application for an Indian allotment was arbitrary and capricious. The magistrate judge granted this motion
*1197
and precluded evidence related to Lowry’s application. Before the magistrate judge, Lowry claimed a right to aboriginal title under
Cramer,
On August 30, 2005, after a two-day trial, the magistrate judge found Lowry guilty of unlawful occupancy. He rejected Lowry’s argument that she was authorized to occupy the land, holding that authorization is an affirmative defense as to which Lowry had not met her burden of proof. The magistrate judge also considered Lowry’s challenges to the denial of her allotment application. Ultimately, he determined that the court lacked jurisdiction pursuant to 25 U.S.C. § 345 to consider the denial of the allotment application and further found that Lowry was not deprived of due process because she had voluntarily opted not to pursue an action in the district court following the denial. He then issued a sentence that required Lowry to leave the disputed land by April 30, 2006.
On July 25, 2006, the district court issued a detailed opinion affirming Lowry’s conviction, but on different grounds. The district court held that authorization was an element of the offense for which the government bore the burden of proof. However, the court then held that any error caused by the magistrate judge’s incorrect rule was harmless because the government had met its burden of proof. The district court also affirmed the magistrate judge’s exclusion of the evidence of Lowry’s Indian allotment application and the determination that the magistrate judge lacked jurisdiction to consider Low-ry’s challenge to the Forest Service’s denial of that application.
II
Lowry appeals her convictions for unauthorized residential occupancy of land in a national forest, see 36 C.F.R. § 261.10(b), and for unauthorized use or occupancy of land or facilities in a national forest, see 36 C.F.R. § 261.10(k). She raises two issues. First, Lowry contends that the magistrate judge erroneously shifted the burden of proof and that the government failed to prove each element of the crime. Specifically, she alleges that the government has the burden of proving that she did not have authorization based on a claim of individual aboriginal title to occupy the Oak Bottom area. Second, Lowry asserts that the magistrate judge precluded her from presenting a defense by excluding evidence that the denial of her Indian allotment application was arbitrary and capricious, because, had the application been granted, would have provided an alternate means of authorization to occupy the land. We address each of Lowry’s arguments in turn.
Ill
Lowry claims that she has individual aboriginal title to the National Forest Service lands she now occupies. Preliminarily, she disputes the burden of proof applied by the magistrate judge as to the authorization requirements in 36 C.F.R. §§ 261.10(b) and (k). Lowry contends that the government has the burden to prove all elements of the crime as defined in the regulations, and to do so, it must establish a negative — that she lacked authorization to occupy the land in question. Consequently, she asserts that the magistrate judge erred by requiring her to establish that she held individual aboriginal title to occupy the land. With respect to the district court’s ruling, Lowry does not challenge the burden of proof applied, but disputes that the government provided sufficient evidence to negate her authorization to occupy the land. The government contends that authorization operates as an *1198 affirmative defense, such that an occupant must raise and prove some right to possession. 3
Our analysis is complicated by the fact that although Lowry challenges the magistrate judge’s rule, she agrees with the one subsequently applied by the district court. The magistrate judge — acting as the trial court — applied the allegedly erroneous burden of proof and convicted Lowry. The district court then rejected the magistrate judge’s allocation of the burden of proof and adopted the rule endorsed by Lowry, but nonetheless upheld the conviction. Consequently, although Lowry disagrees with the magistrate judge in full, she only disagrees with the district court in part: Lowry does not assert that the district court’s rule was plainly erroneous, but that the district court’s application of that rule was plainly erroneous. To assess Lowry’s claim, however, we must first consider the allocation of the burden of proof as to the authorization requirement in 36 C.F.R. §§ 261.10(b) and (k). Only then can we turn to whether that burden was met. Because we reject the rule applied by the district court, we do not ultimately reach the merits of Lowry’s challenge to the district court ruling.
A
Sections 261.10(b) and (k) do not explicitly allocate the burden of proof. The regulations make it a misdemeanor to occupy Forest Service land for residential purposes “without a special-use authorization, or as otherwise authorized by Federal law or regulation.” 36 C.F.R. § 261.10(b). The magistrate judge held that Lowry’s claim to individual aboriginal title was an affirmative defense and that she “had the burden of going forward with these affirmative defenses, since they were not elements of the case in chief.” The district court disagreed, citing its prior decision in
United States v. Lex,
We have not explicitly addressed the allocation of the burden of proof of the authorization requirement in 36 C.F.R. §§ 261.10(b) and (k). In fact, it appears that the burden of proof question is one of first impression in the circuit courts. Because the absence of a special-use authorization or Indian allotment is not disputed here, 4 we do not address the burden of proof as to these potential grounds for authorization. 5 Instead, we consider the *1199 burden of proof as to the specific basis raised here — that is, Lowry’s claim of individual aboriginal title.
We have previously considered whether a claim of individual aboriginal title satisfied the requisite authorization in 36 C.F.R. § 261.10(b) in a case very similar to Lowry’s. In
United States v. Kent,
Lowry argues that
Kent
does not govern her case and that the phrase in 36 C.F.R. § 261.10(b), “without a special use authorization, or as otherwise authorized by Federal law or regulation,” merely “negates an element of the crime” and may not be shifted to the defendant.
See Walker v. Endell,
This approach is consistent with our approach in
Kent,
in which we stated that the person claiming individual aboriginal title must demonstrate continuous individual occupation that commenced before the land in question was withdrawn from entry for purposes of settlement.
See Kent,
Aside from its theoretical support, our approach makes practical sense in this case: given the nature of Lowry’s claim to individual aboriginal title, it would be “far easier for the defendant to present evidence” of her Indian ancestors and their history of land occupancy to establish that the exception applies than for the government to do so.
Freter,
Finally, we consider that if we were to place the burden on the government, we would create a presumption that Indians have an individual aboriginal claim until the United States proves otherwise. Such a presumption might prove unworkable in a number of ways — not the least being that it might subject some national forest system lands to multiple claims of ownership and leave the United States unable to manage its lands effectively. Nothing in the statute requires such a result, and we doubt that was the Secretary’s design in the regulations.
*1201 Having concluded that where authorization is claimed by virtue of individual aboriginal title, it is an affirmative defense to be raised by a defendant, we need not address whether the government provided sufficient evidence to negate Lowry’s right to individual aboriginal title. It is Lowry, and not the government, who has the burden to establish individual aboriginal title. As we explain, we conclude that Lowry has not made even a prima facie showing that she satisfies the requirements for such a claim.
B
The Supreme Court first introduced the doctrine of individual aboriginal title in
Cramer v. United States,
Under Cramer, Dann, and Kent, Lowry must demonstrate her continuous occupancy of the Oak Bottom land. She cannot do so. Although Lowry can demonstrate that at least one of her lineal ancestors, Bessie Tripp, dwelt continuously in the Oak Bottom area between 1926 and 1982, Lowry does not contend that Bessie continuously lived on the parcel of land Lowry currently occupies. Bessie Tripp resided for the period between 1926 and 1982 on Indian Allotment 280, which adjoins, but does not include, the property that Lowry currently occupies. Lowry argues that the distinction between these parcels is immaterial because Bessie Tripp and the other residents of Allotment 280 treated Lowry’s claimed parcel as part of their property. However, as the magistrate judge noted, Bessie resided on private property — Allotment 280 — not on Forest Service land. There is no basis in the case law to expand a claim of individual aboriginal title based on occupancy of one parcel of land to include another parcel that was never so occupied. Moreover, Bessie Tripp and the other residents did not use the claimed parcel in any of the ways discussed in Dann and Kent: There was no enclosure, no cultivation, and no residence on the property now occupied by Lowry. 7 We *1202 conclude that Lowry has not presented evidence of continuous occupancy of the disputed land and consequently, fails to establish her claim of individual aboriginal title.
IV
Alternatively, Lowry argues that the magistrate judge improperly precluded her from presenting evidence of irregularities in the Forest Service’s prior denial of her request for an Indian allotment in 1990. She claims that her inability to challenge that denial violated her due process rights by foreclosing her defense that the Indian allotment proceeding was flawed and that, but for the flaws, she had a plausible ground for obtaining an Indian .allotment. She asserts that, as a consequence, the denial of her allotment application “cannot be used as a critical part of’ the instant criminal prosecution against her.
As the sole support for her collateral challenge, Lowry points to
United States v. Mendoza-Lopez,
Mendoza-Lopez
does not justify Lowry’s collateral attack upon the Forest Service’s recommendation to deny her application for an Indian allotment.

Lowry had a right to seek review of the denial in federal court, 25 U.S.C. § 345, or to file an original action in district court, 28 U.S.C.
*1203
§ 1353.

See Christensen v. United States,
V
For the foregoing reasons, we affirm the judgment of conviction.
AFFIRMED.
Notes
. In. 1988, Lowry received a certificate of eligibility from the Department of the Interior which certifies that she is eligible to obtain an allotment of land in the public domain or in a national forest. However, the letter noted that her “chances of obtaining a Public Domain allotment are severely limited.”
. Although the government initially filed a 23-count information, it eventually brought only the first two charges, both concerning Lowry’s unlawful occupancy. The government also agreed to seek only Lowry’s removal from the land and restitution for clean-up costs rather than a fine or a prison sentence.
. Lowry's challenge to the magistrate judge's interpretation of a statute is a question of law that we typically review de novo.
See United States v. Carranza,
. Although Lowry challenges the government's denial of her Indian allotment application as arbitrary and capricious, an issue we address in section IV, she does not dispute the denial itself.
.There is language in our precedent suggesting that the government must prove the absence of a special-use authorization or an Indian Allotment.
See United States v. Adams,
. Arguably, the same logic may not hold true for records of special-use authorizations and Indian allotments, which the government may keep as to its National Forest Service land. However, as we previously noted, our holding is limited to the burden of proof for authorization based on individual aboriginal title.
. Even assuming that Bessie Tripp's occupancy at Allotment 280 somehow extended to the claimed parcel, Lowry still fails to make out a prima facie case of individual aboriginal title because she has not shown continuous occu
*1202
pancy since before the land was withdrawn from settlement.
See Dann,
. Under 25 U.S.C. § 337, the Secretary of the Interior makes the decision to make an Indian allotment, but his determination must be informed by the Secretary of Agriculture's finding that the land is better suited to agriculture or grazing than to timber. The Forest Service is an agency within the Department of Agriculture.
. It is possible that the Administrative Procedure Act, 5 U.S.C. §§ 701-06, provided an additional avenue for judicial review.
