Opinion
The People appeal from a judgment dismissing criminal charges against respondents following the granting of a motion to suppress evidence obtained pursuant to a search warrant.
*640
Probable cause for the warrant was based on an aerial surveillance of respondents’ land by Madera County law enforcement officers using binoculars to identify a marijuana garden. The trial court granted respondents’ motion to suppress on the theory that the officers’ use of binoculars during the aerial surveillance constituted an unreasonable search under the authority of
People
v.
Arno
(1979)
As we shall explain, Arno does not compel such a result; we conclude that optically aided aerial surveillances of marijuana patches growing in open fields is constitutionally permissible today. Granting the suppression motion on that basis was error.
We then consider respondents’ alternate argument "that misrepresentations and omissions in the affidavit supporting the search warrant invalidate the warrant under
Theodor
v.
Superior Court
(1972)
The Evidence 1
Madera County Deputy Sheriff Albert Hahn, having heard rumors that marijuana was being cultivated on a particular rural parcel of land in Madera County, decided to conduct an aerial surveillance to confirm the rumors. Hahn checked at the assessor’s office to determine the boundaries of the parcel under suspicion. At the assessor’s office he obtained a map of the subject 29-acre parcel, determined that its address was 39900 Road 800, and discovered that it was owned by John and Christina Reed (whom the officer also knew as Christina Joubert).
Hahn arranged for Officer Smith of the California Highway Patrol to serve as pilot. The overflight was conducted on August 24, 1978. Before takeoff, Officer Hahn instructed the pilot that the plane should be flown at an elevation of at least 500 feet. Hahn testified that the airplane did remain above that elevation during the flight. The plane circled the periphery of the subject parcel about 15 to 25 times without flying directly over it.
*641 From that height and distance, Hahn was able to see on the subject parcel a circular-shaped cultivated area approximately 50 feet in diameter. By using “seventeen power” binoculars, the officer was able to see characteristics of the cultivated plants which led him to conclude that they were marijuana. Hahn testified that the type of binoculars he used give a view from 1,000 feet which is equivalent to seeing from a distance of 75 feet with only the naked eye.
Hahn testified that this circular patch was the only place on the 29-acre parcel where he saw something he suspected was marijuana.
Officer Smith, the pilot, also testified regarding his observations during the flight. Smith said that during the time the plane was circling the subject property, it never dropped to an elevation less than 800 feet above the ground. Smith had been advised by Hahn to watch the elevation and keep above 500 feet. 2 However, when studying a map on the morning of the preliminary hearing, Smith figured out that the plane had actually been flying at an elevation of 1,000-1,100 feet. Smith also gave some confusing testimony as to the horizontal distance between the plane and the marijuana garden under observation.
Evidence was also adduced concerning the number of roads and buildings in the vicinity of the marijuana garden. This evidence was introduced to support an attack on the search warrant on the ground that it was overly broad in specifying that the entire 29-acre parcel and buildings thereon could be searched. Officer Smith testified there was more than one building on the parcel in question. Some outbuildings resembling barns were near one “predominant house.” This house was the focus of particular attention during the overflight, but there were also several other buildings in the vicinity. There was also evidence to show that the area was about to be subdivided and that some work had been started on the roads. Officer Hahn testified there were “numerous roads” in the area.
A search warrant for the subject parcel and all buildings thereon was issued in response to an affidavit filed by Officer Hahn the day after the overflight described above.
On August 30, 1978, the search warrant was executed. The officers seized about 100 marijuana plants found growing on the circular field *642 which had been seen from the air. They also seized over 150 marijuana plants from gardens at various other locations on the property. The relationship among the various marijuana growing sites was as follows. The circular garden containing 100 marijuana plants was located approximately 15 feet from a house trailer where respondent Vanderpool was seen during execution of the warrant. There was a footpath from that trailer to the circular garden. Approximately 75 yards from that garden was a cabin where there were 2 more marijuana patches: 1 containing 54 plants and the other containing 82 plants. A third structure which appeared to be a house under construction was located about 400 yards from the circular garden. Just a few feet away from this house there was a fenced in area containing rose bushes as well as about 39 marijuana plants. Near this garden were two bags of fertilizer which were seized, and then later returned to respondent Christina Joubert at her request.
The Binocular Aided Aerial Surveillance Was Lawful
In
People
v.
Edwards
(1969)
The premier California case on optically aided aerial surveillance of marijuana cultivation is
Dean
v.
Superior Court
(1973)
Dean first acknowledged that a property holder may have a Fourth Amendment right of privacy in the air corridor above his land. “Expectations of privacy are not earthbound. The Fourth Amendment guards the privacy of human activity from aerial no less than terrestrial invasion .... Reasonable expectations of privacy may ascend into the airspace and claim Fourth Amendment protection.” (Id., at p. 116.)
Dean then held that “mankind’s common habits in the use of domestic and business property supply a prime measure of the reasonableness of expectations of privacy.” (Id., at p. 117.) “One who builds a swimming pool and sun-bathing area in his backyard expects privacy (hence immunity) from aerial inspection. Areas reasonably used in ordinary business operations are assumedly entitled to similar immunity. Such areas are expectedly private according to the common habits of mankind.” (Ibid.)
However: “One who establishes a three-quarter-acre tract of cultivation surrounded by forests exhibits no reasonable expectation of immunity from overflight. The contraband character of his crop doubtless arouses an internal, uncommunicated need for secrecy; the need is not exhibited, entirely subjective, highly personalized, and not consistent with the common habits of mankind in the use of agricultural and woodland areas. Aside from an uncommunicated need to hide his clandestine activity, the occupant exhibits no reasonable expectation of privacy consistent with the common habits of persons engaged in agriculture. The aerial overflights which revealed petitioner’s open marijuana field did not violate Fourth Amendment restrictions.” (Id., at pp. 117-118, fn. omitted.)
In
Burkholder
v.
Superior Court
(1979)
Nor did the fact that the officer’s observations were optically aided compel a contrary conclusion in
Burkholder.
Although the evidence revealed that the cultivated patch was visible to the naked eye and the evidence reasonably supported an inference that the patch was marijuana, the court held “.. . the determinative factor is whether a reasonable expectation of privacy existed entitling the claimant to be free from clandestine surveillance, whether by natural
or
artificial means.”
(Id.,
at p. 426, italics in original.) Quoting from
People
v.
Arno, supra,
The most recent published decision involving optically aided aerial discovery of marijuana cultivation is
People
v.
St. Amour
(1980)
The plane circled the area and one officer used ordinary and then gyrobinoculars from 1,000 or 1,500 feet to examine the garden. The *645 gyrobinoculars stabilized the view, eliminating the effect of the plane’s movement and vibration to facilitate the observations. The officers verified that the garden was marijuana growing on about one-quarter of an acre. The garden was on the side of a mountain slope in a deserted area. The nearest town was a mile and a half away. No business or other human activity was observable from the air.
In upholding the aerial surveillance, the court stated: “While the constitutional privilege of protecting one’s privacy covers not only the ground, but may extend also into the airspace, it is absolutely essential that the person affected exhibit a reasonable expectation (as opposed to mere subjective, personal desire) that the activity in question be so protected. The reasonable expectation to protect the airspace overlying the land, however, cannot be demonstrated by measures taken to defend the land from earthly intrusions (e.g., by setting up a road block, trespass signs or by hiding the area or activity from ground observations). Rather the individual seeking constitutional safeguards must show that the land is used in accordance with the common habits of people engaged in the cultivation of agricultural land who exhibit an expectation of privacy with respect to the pursuit in question.” (Id., at p. 891.)
In reaching its conclusions,
St. Amour
adopted the reasoning of
Dean
and
Burkholder
that “[o]ne who establishes a. . .tract of cultivation surrounded by forests exhibits no reasonable expectation of immunity from overflight”
(St. Amour
at p. 892, quoting from
Dean
v.
Superior Court, supra,
The Supreme Court of Hawaii has also spoken on the subject of optically aided overflights of marijuana patches. In
State
v.
Stachler
(1977)
In upholding the constitutionality of the aerial observation, the court noted that the helicopter was flying at a lawful and reasonable height so that the officer had a right to be where he was at the time of the aerial observation (id., at p. 1327); it then applied the Dean rationale that one who farms marijuana should be in no better position than one who farms a lawful crop insofar as the constitutional right of privacy. “If defendant had been engaged in growing taro, sweet potato or banana, surely he would not have a reasonable expectation of privacy as to his crop from aerial observation. And, society as a whole would not find such an expectation of privacy objectively reasonable according to the common habits of mankind.” (Id., at p. 1328.) The court concluded that since the defendant did not have a reasonable expectation of privacy from aerial observation conducted at a reasonable height as to his open marijuana patch, it followed that the helicopter surveillance was not a search in the constitutional sense.
We glean from these cases two overriding principles: first, although police officers conducting overflights have demonstrated a rather remarkable visual capability in spotting marijuana gardens, the plants cannot truly be identified as marijuana at reasonable altitudes without the aid of binoculars; second, a binocular aided aerial examination from a lawful altitude does not infringe on a property holder’s constitutional right of privacy; the courts consistently have refused to recognize a right to be free from such intrusion. Thus, anyone who grows marijuana in the open today does so at the risk of being spotted by flying police officers. Only by growing the marijuana in a hothouse or otherwise covering the plants to shield them from aerial observation will the property holder be deemed to have demonstrated an objectively reasonable expectation of privacy from overflights.
Appellant argues that the principles articulated in
People
v.
Arno, supra,
The officers surveyed the building using binoculars, looked into the open window of the eighth floor suite and saw the defendant handle a distinctively marked box displaying a label with a picture of a nude woman. The box contained eight millimeter film. The product of the officer’s observations found its way into an affidavit in support of a search warrant leading to the seizure of the pornographic film.
In holding the binocular aided scrutiny of the defendant’s conduct constitutionally invalid, Arno articulated the following: “(1) the use of optical aids in the nature of binoculars, telescopes and the like is not itself determinative of the admissibility in evidence of the product of the observation; (2) the primary determinative factor is the presence or absence of a reasonable expectation of privacy of the person whose conduct, property, or documents is observed; (3) reasonable expectation of privacy... is tested by the extent to which the person has exposed his conduct, property, or documents to public view by the naked eye; (4) if the purpose of the optically aided view is to permit clandestine police surveillance of that which could be seen from a more obvious vantage point without the optical aid, there is no unconstitutional intrusion. ...” {Ibid., italics added.)
Arno does not help appellant; growing marijuana in an open area out of doors is a far cry from handling contraband in a business office several stories above the street level. A business person normally would expect that his conduct in the privacy of the office would be free from outside surveillance unless he knowingly exposes his conduct to the open view of those outside the office, On the other hand, according to the published cases anyone who grows marijuana in an open field does not have an objectively reasonable expectation of privacy insofar as overflight at lawful altitudes.
We are not unconscious of the legitimate concern about the activities of the government as “Big Brother.” Good arguments can be made that a citizen should be able to possess a few acres of mountainous land in a rural area and be protected from governmental intrusion into his activities thereon, short of the necessity to preserve human life or property. Ample authority exists for the proposition that although the possessor of rural lands should anticipate the presence of hikers, hunters and trespassers on his land he need not anticipate the presence of police officers
*648
engaged in exploratory searches. The concept of a
particularized
objective right to privacy is recognized in recent cases. For example, in
Phelan
v.
Superior Court
(1979)
Nevertheless, whether a citizen should be deemed to have an objective right of privacy from optically aided aerial surveillance of his activity on isolated rural mountain land is a question of public policy. Until such time as the Supreme Court speaks to the contrary, we feel constrained to follow the clear mandate of the published decisions which have spoken on the point.
*649 Respondents’ Contentions as to Misstatements and Omissions in the Affidavit Supporting the Search Warrant
At the suppression hearing in the superior court, respondents sought to have the search warrant invalidated on the ground there were substantial misstatements and omissions in the affidavit in support of the search warrant. The trial court rejected this argument and suppressed the evidence only on the ground that the binocular search was illegal.
We have examined respondents’ asserted misstatements and omissions and we find that most of them would be relevant only to the question of the lawfulness of the aerial surveillance. 4 Since we hold the aerial surveillance was lawful because respondents had no reasonable expectation of privacy from overflight, the asserted misstatements and omissions as to the size of the cultivated area and the altitude and distance of the airplane from the garden become irrelevant.
Respondents also assert that the affidavit omits any reference to the “numerous roads” in the area and makes no mention of the “numerous dwelling houses” in the vicinity of the marijuana garden, stating only that the affiant believed there was evidence in the dwelling house. The affidavit does mention that there is more than one structure on the property to be searched; however, it does not specify the character of each individual structure. Page one thereof describes the place to be searched as “a 28 acre parcel of real property located at 39900 Road 800, Madera County, California, .. . consisting of open fields forested with oak trees, brush and grass, upon which sit several single story structures appearing to be dwelling places and/or outbuildings and those dwelling places and/or outbuildings.” (Italics added.) The affiant further stated: “[Y]our affiant has formed the expert opinion that the dwelling house located at 39900 Road 800. . . contains such evidence as to the identity of the persons occupying and controlling the property, as well as such items used to cultivate, process and prepare for sale marijuana.” (Italics added.)
*650
People
v.
Kurland
(1980)
Respondents have asserted that the affidavit should have included the fact that there was more than one dwelling house on the property. We conclude that this assertion was enough to satisfy their initial burden under
Kurland
because it would be material to the magistrate issuing the warrant to know that there were several different habitations on the premises as opposed to merely one habitation with attendant outbuildings for farming purposes. Such facts are material, because if the affidavit showed on its face that there were multiple separate dwellings on the premises, then the magistrate could only issue a warrant for each of these dwellings (and whatever zones of privacy existed around each of them) upon a showing of probable cause as to each dwelling (cf.
People
v.
Sheehan
(1972)
*651
Since the number of separate residential units on the subject property was material to a determination of probable cause, respondents made a sufficient showing to require a hearing under
Kurland
(
As to respondents’ overbreadth argument, the trial judge similarly truncated argument at the suppression hearing. On remand, if the superior court concludes after a hearing on the
Kurland
issue that the officers had no reason to know there were multiple dwellings on the property, then the principles expressed in
United States

Rios, supra,
The judgment is reversed and the matter is remanded to the trial court with directions to conduct a hearing in accordance with the principles announced herein.
Hanson (P. D.), J., and Evans (C. P.), J., * concurred.
Respondents’ petition for a hearing by the Supreme Court was denied June 24, 1981.
Notes
This summary of the evidence is derived from the preliminary hearing transcript which was considered by the superior court judge in ruling on the suppression motion. No additional evidence was offered at the superior court hearing.
There is an FAA regulation forbidding flights over dwelling houses at less than 500 feet.
Katz
v.
United States
(1967)
Respondents assert that the circular marijuana garden was not 50 feet in diameter as set forth in the affidavit but was actually smaller; that the airplane during observations of the marijuana was not flying at a height of between 500 and 800 feet as Hahn stated in the affidavit but at a height of 1,000 to 1,100 feet; and that the affidavit fails to mention that the airplane was one to three miles away from the marijuana patch during the surveillance.
