This сase requires us to determine whether Arizona’s 10% cap on nonresident hunting of bull elk throughout the state and of antlered deer north of the Colorado River substantially affects commerce such that the dormant Commerce Clause applies to the regulation. We hold that it does. We further hold that the regulation discriminates against interstate commerce, but that Arizona has legitimate interests in conserving its population of game and maintaining recreational opportunities for its citizens. We remand for further proceedings to determine whether Arizona has met its burden of showing that these interests could not be served adequately by reasonable nondiscriminatory alternatives.
I.
BACKGROUND
Arizona is home to what is considered by many hunters to be some of the best deer and elk hunting in the world, exemplified by the world record animals harvested from its lands. The part of Arizona north of the Colorado River, called the “north Kaibab” and “Arizona strip,” is a particularly scenic area known for its trophy elk
The quality of the hunting in Arizona is in large part a result of the conservation efforts supported by Arizona citizens and administered by the Arizona Department of Game and Fish (“Department”). The native Merriam elk was extirpated from Arizona in 1898. The present elk population descends from the Wapiti variety introduced to Arizona in 1913. In the case of both deer and elk, the maintenance of the state’s herds has been ensured over the years through strict regulation of the number of hunting permits, known as “tags,” issued each year.
For many years, Arizona distributed the limited tags made available for antlered deer and bull elk hunting through a lottery without regard to the residency of the applicant.
In response to the pressure from Arizona hunters, the Department in 1991 amended Rule 12-4-114 of the Arizona Administrative Code to place a 10% cap on the number of tags that could be awarded to nonresidents for the hunting of bull elk throughout the state and for antlered deer in the area north of the Colorado River.
The Statement explained that “10% was chosen to be consistent with other limits on buffalo and bighorn sheep already established” in Arizona. It also stated that “most states have some type of nonresident restriction in hunts for species that are sought after.” According to Department officials, the 10% cap was imposed because it is “comparable with systems of limitations that are placed upon [Arizona residents] when they are a nonresident [sic] in another state.” Cf. Terk v. Ruch,
In addition to the 10% cap, the Department adopted a bonus point system for the tag lottery. Ariz. Admin. Code R12-4-107
Each plaintiff is a professional hunter and guide residing in New Mexico who applies for hunting tags around the country in order to obtain the meat of the animals, their hide, their ivories, and especially their head and rack of antlers to profit from the sale and use of the nonedible parts. Plaintiffs have applied for Arizona tags to hunt bull elk as well as antlered deer north of the Colorado River for this commercial purpose, but have never received a tag. They intend to continue applying for tags for hunts restricted by the 10% cap. In the hunts between 1997 and 1999 in which the plaintiffs applied for tags, nonresidents constituted between 15% and 51% of the applicants and received between 6% and 10% of the tags.
Arizona law prohibits the commercial exchange of the edible portions of a harvested animal, but allows the sale of the nonedible portions. There is an interstate and international market for the antlers and hides of deer and elk. Poor quality elk antlers, largely supplied by ranches raising elk for this purpose, are sent to Korea where they are processed into a nutritional supрlement. Better quality antlers of elk and deer, almost entirely supplied by hunters, are used for display and for creating art and furniture and can sell for hundreds to thousands of dollars, up to $50,000 for the very best.
Plaintiffs’ suit originally claimed that the Arizona regulation violated the Commerce, Privileges and Immunities and Equal Protection Clauses of the U.S. Constitution and requested a declaration of invalidity as well as damages. The district court granted the Department’s cross-motion for summary judgment on the Commerce Clause claim. Plaintiffs voluntarily dismissed the remaining counts of their complaint and filed this appeal. We review the grant of summary judgment de novo. See Lite-On Peripherals, Inc. v. Burlington Aire Express, Inc.,

DISCUSSION
The Supreme Court’s “negative” or “dormant” Commerce Clause jurisprudence is forged from thе tension between the Constitution’s commitments that our nation be united, free of “conflicting] ... commercial regulations, destructive to the harmony of the States,” Gibbons v. Ogden,
Under the Articles of Confederation, the balance decidedly favored the autonomy of states with the result that “[w]hen victory relieved the Colonies from the pressure for solidarity that war had exerted, a drift toward anarchy and commercial warfare between states began” in which “each state would legislate according to its estimate оf its own interests, the importance of its own products, and the local advantages or disadvantages of its position in a political or commercial view.” H.P. Hood & Sons, Inc. v. Du Mond,
Although the Commerce Clause is phrased as an affirmative grant of regulatory power to Cоngress, the Supreme Court “has advanced the solidarity and prosperity of this Nation” by giving meaning to the Clause’s “great silences.” H.P. Hood,
A. Applicability of the dormant Commerce Clause.
The district court concluded that the Commerce Clause does not apply to Arizona’s regulation of hunting tags because hunting is “recreation,” which is not “a form of interstate commerce,” and because parts of elk and deer do not become articles of commerce until they are “reduced to possession” by a hunter. The district court based these conclusions on the Supreme Court’s holding in Baldwin v. Fish & Game Comm’n,
The question before the Supreme Court in Fish & Game Comm’n was whether the Privileges and Immunities Clause applied to a Montana law charging out-of-state residents a higher fee for recreational elk hunting licenses. The Court held that the Privileges and Immunities Clause does not apply to such a law because that clause addresses only distinctions in the exercise of those fundamental rights “bearing upon the vitality of the Nation as a single entity,” such as burdens on the pursuit of common callings, the ownership and disposition of privately held property and access to the courts.
Fish & Game Comm’n does not foreclose application of the dormant Commerce Clause here. Although the Commerce and Privileges and Immunities Clauses have a “mutually reinforcing relationship” stemming “from their common origin in the Fourth Article of the Articles of the Confederation and their shared vision of federalism,” Hicklin v. Orbeck,
In Camps, the Supreme Court held that a Maine law that extended beneficial tax treatment to operators of nonprofit camps that served mostly Maine residents violated the dormant Commerce Clause.
In addition to substantially affecting the interstate flow of people, hunting in Arizona substantially affects the interstate flow of goods in commercial markets. Congress has noted, in another context, that regulation of hunting “endangered species of wildlife with some commercial value” affects interstate commerce, because with “controlled exploitation ... businesses] may profit from the trading and marketing of that species ..., where otherwise it would have been completely eliminated from commercial channels.” S.Rep. No. 91-526 (1969), reprinted in 1969 U.S.C.C.A.N. 1413, 1415.
The statement in Hughes that “when a wild animal becomes an article of commerce ... its use cannot be limited to the citizens of one State to the exclusion of citizens of another” is not to the contrary. Hughes,
We conclude that because hunting of bull elk and antlered deer in Arizona substantially affects interstate commerce, as do Arizona’s restrictions on that hunting by nonresidents, the dormant Commerce Clause is applicable here.
B. Validity of Arizona’s nonresident cap.
Our conclusion that Arizona’s regulation of hunting substantially affects interstate commerce does not answer the question of whether the regulation violates the dormant Commerce Clause. The existence of unexercised federal regulatory power does not categorically foreclose state regulation. Sporhase v. Nebraska,
A state discriminates against interstate commerce by treating differently in-state and out-of-state economic interests, including consumers of natural resources, such that the regulation benefits the former and burdens the latter. Or. Waste Sys.,
The district court held that, even if the dormant Commerce Clause applied to Arizona’s cap on nonresident hunting, the plaintiffs failed to show under Pike that the cap imposed a burden on interstate commerce clearly excessive in relation to its putative local benefits. We disagree with the district court’s conclusion that Pike was the appropriate standard to apply because Arizona’s cap on nonresident hunting licenses is not an even-handed regulation. It restricts access to Arizona’s population of bull elk and antlered deer based on whether the hunter is a resident of Arizona. This overt discrimination in access to Arizona’s resources is subject to the strictest scrutiny under the dormant Commerce Clause. City of Philadelphia v. New Jersey,
1. Legitimate interests.
We turn first to whether Arizona has set forth legitimate interests for its regulation of hunting. Although the Supreme Court has adopted a broad construction of the applicability of the dormant Commerce Clause, it has cautioned that “[t]he Commerce Clause ... does not elevate free trade above all other values.” Maine v. Taylor,
Arizona’s cap on nonresident hunting was designed to serve its interests in conserving the population of game on its lands while maintaining recreational hunting opportunities for its citizens. These interests are unquestionably legitimate. The protection of wildlife and other natural resources of a state are some “of the state’s most important interests.” Pac. N.W. Venison Producers v. Smitch,
A state may have additional interests in granting “in times of severe shortage ... a limited preference for its own citizens in the utilization of [a] resource” that, through the state’s conservation efforts, “has some indicia of a good publicly produced and owned.” Sporhase,
Where the resource in question is “produced” by conservation, rather than being “the end product of a complex process [by the state] whereby a costly physical plant and human labor act on raw materials,” Reeves,
An important difference noted in Spo-rhase is that water is a “vital resource” the regulation of which directly serves “the purpose of protecting the health of its citizens,” an interest that lies “at the core of its police power.” Id. at 956; see also Or. Waste Sys.,
We conclude that Arizona has met its burden under the first part of the strict scrutiny analysis. It has legitimate interests in preserving the health of its game populations and maintaining recreational hunting opportunities for its citizens. The key question in our analysis, then, is whether Arizona has met its burden under the second pаrt of the inquiry by demonstrating that the cap is narrowly tailored to its legitimate ends.
2. Narrow tailoring.
The Supreme Court’s narrow tailoring analysis under the dormant Commerce Clause focuses on the requirement that the state “demonstrate, under rigorous scrutiny, that it has no other means to advance a legitimate local interest.” C & A Carbone,
As we noted above, the scarcity of Arizona game does not itself justify discrimination against out-of-state access to hunting. The Commerce Clause does not permit a state to “force those outside the State tо bear the full costs of ‘conserving’ the wild animals within its borders when equally effective nondiscriminatory conservation measures are available.” Hughes,
Arizona cannot meet its burden of showing thаt its cap on nonresident hunters is narrowly tailored to its conservation interest simply by demonstrating that Arizona residents desire similar or more severe restrictions on nonresident access to hunting, even if Arizona could show that residents conditioned their support of the government’s programs on the adoption of such discrimination. In Fish & Game Comm’n, the Supreme Court rejected a similar argument, stating that under the Privileges and Immunities Clause “the State’s need or desire to engender political support for its conservation programs cannot by itself justify an otherwise invidious classification.”
Nor can Arizona show that its 10% cap on nonresident hunting is narrowly tailored to serve legitimate interests because other states have similarly restricted nonresident hunting. Discrimination against interstate commerce “cannot, of course, be justified as a response to another State’s unreasonable burden on commerce.” Sporhase,
We do not foreclose the possibility that the goal of ensuring a state’s citizens’ access to recreational opportunities may justify limited consideration of residency in the allocation of hunting tags in some circumstances. Whether there is a need for such consideration for hunting in Arizona turns on questions of fact not appropriate for resolution by this court. It is hardly clear that Arizonans need preferences in order to enjoy hunting in their state. The Statement accompanying the promulgation of the regulations explained that, without the cap or bonus point system, “most big game hunts ... experience nonresident pressure below 5%,” and that Arizonans received over 80% of the hunting tags issued for nearly every hunt for bull elk statewide and for antlered deer north of the Colorado River. A factfinder reasonably could conclude from this evidence that Arizona’s regulation was designed to respond to political pressure from the Department’s constituency, not to any actual need of Arizonans for more hunting opportunities.
Even if Arizona can show that some effort is needed to ensure that its citizens have access to recreational hunting, a question of fact remains whether a cap on nonresident hunting is the “least discriminatory alternative” to serve Arizona’s interests. Hughes,
We hold that Arizona’s cap on nonrеsident hunting substantially affects and discriminates against interstate commerce and therefore is subject to strict scrutiny under the dormant Commerce Clause. Arizona has legitimate interests in regulating hunting to conserve its population of game and maintain recreational opportunities for its citizens. We remand for further proceedings to determine whether Arizona has met its burden of showing that it has no other means to advance its legitimate interests.
REVERSED AND REMANDED.
Notes
. Only antlered deer and bull elk, the favored targets of big game hunters because of their size, scarcity and "trophy” of antlers, are subject to the restrictions at issue in this case.
. According to the Department, Arizona hunters are thought of as its "consumer base”; "our customers.” Department officials justify the nonresident cap as "an attempt to reward Arizona's citizens for their ongoing support.”
. We agree with the district court that these facts are sufficient to satisfy the elements of standing. See N.E. Fla. Chapter, Associated Gen. Contractors of Am. v. City of Jacksonville,
. This expansive reading of the Commerce Clause and its goals is derived in part from the writings of James Madison, one of the Clause’s chief architects. 1 Laurence H. Tribe, American Constitutional Law § 6-3, at 1044-45 (3d ed.2000) (explaining the "Madi-sonian” roots of the Court's interpretation of the Commerce Clause).
. “The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States.”
. Other courts have adopted similar reasoning in cases where, unlike in Arizona, the state prohibits the sale of all parts of the animal harvested. See Terk,
. Contrary to the district court's finding, even if the regulated activity is not itself "a form of interstate commerce,” it may still substantially effect interstate commerce and therefore be subject to the Commerce Clause. In the Supreme Court’s early jurisprudence, the Court resolved dormant Commerce Clause cases by categorically distinguishing between invalid regulations of "interstate commerce” and valid exercises of "that immense mass of legislation, which embraces everything within the territoiy of a State, not surrendered to the general government,” Gibbons,
.This report accompanied a reauthorizalion of the Lacey Act, making it “unlawful for any person to import, export, transport, sell, receive, acquire, or purchase in interstate or foreign commerce any fish or wildlife taken, possessed, transported, or sold in violation of any law or regulation of any State or in violation of any foreign law.’’ 16 U.S.C. § 3372(a)(2)(A). Even where the speсies hunted has no current commercial value, Congress may regulate under its Commerce Clause authority to “prevent[ ] the destruction of biodiversity and thereby protect[ ] the current and future interstate commerce that relies upon it.” Nat’l Ass’n of Home Builders v. Babbitt,
. In Fish & Game Comm’n, the Court explained that "[e]lk are not hunted commercially in Montana,” there being "statutory restrictions ... on the buying and selling of game animals, or parts thereof.”
. Hughes overruled Geer, which upheld a ban on the killing of certain wild birds for the purposes of interstate export on the theory that the state owned the wild animals within its borders and thus had the “right to keep the property, if the sovereign so chooses, always within its jurisdiction for every purpоse."
. According to Professor Ely, the Privileges and Immunity Clause and the Commerce Clause ensure a system of "virtual representation” whereby states are prohibited from treating the nonrepresented less favorably than the represented:
An ethical ideal of equality is certainly working here, but the reason inequalities against nonresidents and not others were singled out in the original document is obvious: nonresidents are a paradigmatically powerless class politically. And their protection proceeds by what amounts to a system of virtual representation: by constitutionally tying the fate of the outsiders to the fate of those possessing political power, the framers insured that their interests would be well looked after.
Id. at 83.
. The district court may, for example, wish to explore whether a nondiscriminatory version of Arizona's bonus point system could further its interests.
