Kеlly Kay Wegner (“Wegner”) appeals her sentence under the Sentencing Guidelines following her guilty plea for drug manufacturing and trafficking. She argues that the district court miscalculated her base offense level by erroneously applying the one kilo *925 gram to one marijuana plant conversion ratio in U.S.S.G. § 2Dl.l(e) n.*.
FACTS AND PRIOR PROCEEDINGS
On November 10,1992, Kelly Wegner pled guilty to one count of an indictment alleging that she manufactured and possessed with intent to distribute “at least 100 marijuana plants.” Wegner admitted to growing and harvesting marijuana in the basement of her rented house. She, however, maintained that the number of plants involved was less than one hundred, and objected to having her sentence based on the number of plants grown over a period of time but not seized by the government. Instead, she claimed that only the dry weight of marijuana actually produced by the plants, approximately 10 to 20 kilos, should be used for determining her base offense levеl. With her Criminal History Category of II, this would have resulted in a base offense level of 16 under U.S.S.G. § 2D1.1.
The government contended that between 100 and 400 individual marijuana plants had been grown and harvested by the defendant personally and that she should be sentenced according to the number of plants. This would result in a base offеnse level of 26 under U.S.S.G. § 2D1.1.
The court found that the defendant had been involved in growing and harvesting at least 100 individual plants. The court ruled that the defendant’s base offense level should be determined, not by the actual dry weight of marijuana harvested, but by treating each plant as one kilogram. In making this determination the cоurt relied on a note to § 2Dl.l(c) of the Sentencing Guidelines:
In the ease of an offense involving marihuana plants, if the offense involved (A) 50 or more marihuana plants, treat each plant as equivalent to 1 KG of marihuana; (B) fewer than 50 marihuana plants, treat each equivalent to 100 G of marihuana. Provided, howеver, that if the actual weight of the marihuana is greater, use the actual weight of the marihuana.
U.S.S.G. § 2Dl.l(c) n * (1993).
The court found that the Guidelines’ sentencing range for Wegner would be between 60 and 63 months. Due, however, to her substantial, continuing cooperation with the government investigation, the district court departed downwаrd under Rule 35(b) 1 and imposed a sentence of only 20 months.
ANALYSIS
Applicability of One Kilo Conversion Ratio
I. Standard of Review
A district court’s interpretation of the Sentencing Guidelines is reviewed de novo.
United States v. Buenrostro-Torres,
II. Discussion
The single issue presented is whether the district court was correct in applying the one kilogram conversion ratio when the marijuana plants upon which the charge and sentence were predicated were never in fact actually seized. Proof of the grow operation and the number of plants involved was established by presentation of evidence of: partial plant remains; other circumstantial evidence found at the scene; and testimony of the defendant and other witnesses obtained aftеr the grow operation had been shut down.
Citing
United States v. Corley,
The defendant’s argument is meritless, and her reliance on
Corley
and related cases is misplaced. Under 21 U.S.C. § 841 and the Sentencing Guidelines controlling
Corley,
that is, pre-1989 Guidelines, there was no
*926
one kilogram conversion ratio for marijuana plants. Each plant was equated with 100 grams of marijuana.
In an amendment of the U.S.S.G. effective November 1, 1989, however, the Commission modified § 2Dl.l(c), and introduced the one kilogram conversion ratio when the crime involved 50 or more marijuana plants. 2 U.S.S.G., App. C, Amend. No. 125 (1994).
We have previously held that the rationale behind this amendment was Congress’ intent to punish the manufacture of marijuana more severely.
See United States v. Jordan,
[The one kilogram conversion ratio] is not designed as a substitute for individualized determinations regarding the actual weight of harvestable marihuana taken from a given plant. Instead, it functions only as a measure of culpability for sentencing purposes by assigning an increased level of culpability to marihuana growers as opposed to mere possessors.
Jordan,
Our precedent unambiguously endorses the view that the one kilogram conversion ratio represents congressional intent to punish growers of 50 or more marijuana plants to a greater extent than smaller producers or mere possessors. The defendant’s argument that she should be spared application of that one kilogram equivalency rаtio because termination of the grow operation eliminated all the productive character of the plants involved is, therefore, meritless. 3
Circuit courts of appeals, however, are split on whether the one kilogram conversion ratio is applicable when plants are not seized. This appears to be a case of first impression in this circuit.
The Seventh Circuit, in
United States v. Haynes,
The Second, Sixth, and Eleventh Circuits, however, have chosen not to follow this rule. 4 Nothing in .these decisions persuades us to their holding.
In
United States v. Blume,
Uneontroverted evidence indicates that [the defendant’s] farms produced an аmount of marijuana substantially less than that used for sentencing.... [T]he amounts harvested were certainly less than one kilogram per plant.... Because the evidence does not support finding upon which the district court imposed sentence, we remand for resentencing.
Blume,
The Eleventh Circuit in
United States v. Osburn,
Defendants correctly identify an аnomaly in the statutory scheme. Under Section 841(b), a grower who is arrested immediately after she has harvested her marijuana crop will be sentenced according to the weight of the marijuana yielded by that crop. Yet, a similarly situated grower, arrested immediately prior to harvesting his crop, will be sentеnced on a 1000-gram-per-plant basis. In this example, two people, almost identically situated will be treated in an appreciably different manner.
Id.
In effect, the Eleventh Circuit assumes that the one kilogram conversion ratio does not apply to plants which have not actually been seized, and in so doing creates the very statutory anomaly it considers. Application of the one kilogram conversion ratio in accord with our holding, like application of the rule adopted by the Seventh Circuit in Haynes, prevents this anomaly by treating alike both of the defendants described in the Eleventh Circuit’s hypothetical.
In
United States v. Stevens,
The Sixth Circuit first correctly notes that prior to the introduction of the one kilogram conversion ratio, the Sentencing Guidelines provided for punishment of possession or production of plants or dry marijuana in a roughly similar manner. It states further that while courts had little trouble applying this provision of the Guidelines, they did, however, encounter difficulty applying the previous version of 21 U.S.C. § 841(b) which called for sentencing based only on thе weight of marijuana. Given this statutory provision, sentences could differ greatly depending upon whether a court considered the total wet plant weight or only the weight of the dry harvestable amount of marijuana. According to the Sixth Circuit, this ambiguity resulted in a debate as to how plants should be weighed for purpоses of sentencing under § 841(b).
Stevens,
*928
The Sixth Circuit states that § 6479 of the Anti-Drug Abuse Act of 1988, codified in the current amended version of 21 U.S.C. § 841(b), represented Congress’ attempt to resolve this debate.
Stevens,
Based on these considerations, the Sixth Circuit concludes:
[t]he important point emerging from this history is that under the initial editions of the Guidelines, harvested marijuana was to be measured by weight, not by the number of plants that the marijuana came from, and neither Congress nor the Sentencing Commission has еver repudiated this proposition. The equivalency provision was developed to apply in sentencing when the plants have not been harvested.
Stevens,
While we agree with much of the Sixth Circuit’s analysis of legislative history, we do not believe that it supports the conclusion that the one kilogram conversion ratio does not apply when plants are not seized. The Sixth Circuit, without further reliance on case law or argument, concludes that this history implies that reliable evidence as to plants, even if not seized, must be for sentencing purposes transformed into evidence of a proportionate amount of dry harvested marijuana. Nowhere, however, does the statutory language restrict the nature of the evidence which must underlie the sentence or require the conversion of evidence of plants into dry marijuana. 6 The statute simply provides that the one kilogram conversion apрlies whenever the violation “involves” a “mixture” of the substance or “plants.”
The discussion in Stevens does not indicate that our holding is inconsistent with legislative history prior to the amendment of § 841. Even if it did, we conclude that significant changes in § 841(b) would be sufficient to indicate that prior interpretation of the statute need not be dispositive of its current application.
The Guidelines provide that the one kilogram conversion ratio is to be applied “in the case of an offense involving marihuana plants, if the offense involved (A) 50 or more marihuana plants.” U.S.S.G. § 2Dl.l(c) n.*. When sufficient evidence establishes that defendant actually grew and wаs in possession of live plants, then conviction and sentencing can be based on evidence of live plants. The fact that those plants were eventually harvested, processed, sold, and consumed does not transform the nature of the evidence upon which sentencing is based into processed marijuana.
CONCLUSION
Like the Seventh Circuit, we have interpreted congressional intent in § 2Dl.l(c) n.* to be to punish the producers of marijuana plants more severely than mere possessors.
Jordan,
The count to which the defendant pled guilty explicitly refers to “marijuana plants”; the defendant admits in her plea agreement *929 that she grew and harvested plants; and the defendant does not appeal the lower court’s finding that one hundred plants were involved. We conclude that the district court’s application of the one kilogram equivalency-ratio conforms to the plain language of U.S.S.G. § 2Dl.l(e) n.* and to our interpretation of congressional intent represented by this provision.
AFFIRMED.
Notes
. "The court ... may reduce a sentence to reflect a defendant's subsequent, substantial assistance in the investigation or prosecution of another person who has committed an offense.... The court's authority to reduce a sentence under this subsection includes the authority to reduce such sentence to a level below that established by statute as a minimum sentence.” Fed.R.Crim.P. 35(b).
. The one plant =100 grams rule is carried over into the current Guidelines for crimes involving less than 50 plants:
In cases involving fifty or more marihuana plants, an equivalency of one plant to one kilogram of marihuana is derived from the penalty provisions of 21 U.S.C. § 841(b)(l)(A)(B) and (D). In cases involving fewer than fifty plants, the statute is silent as to the equivalency. For cases involving fewer than fifty plants, the Commission has adopted an equivalency of 100 grams per plant, or the actual weight of the usable marihuana, whichever is greater. The decision to treat each plant as equal to 100 grams is premised on the fact that the average yield from a mature marihuana plant equals 100 grams of marihuana.
U.S.S.G. § 2D1.1 backg'd Commentary (1994).
. This conclusion is also supported by our statement in
United States v. Traynor,
[t]he direction of authority is not to consider a particular plant’s potential for abuse when applying the straightforward language of 21 U.S.C. § 841(b)(1)(D), which basеs sentencing on "50 or more marihuana plants regardless of weight." The language of the statute is plain. As the district court pointed out, "[a] marijuana plant is a marijuana plant."
Id. at 1160.
. The defendant, and the Sixth Circuit in
United States v. Stevens,
In the present casе, the sentence was based on testimony as to the number of live plants grown and possessed by the defendant.
. The legislation amended the United States Code providing for a mandatory minimum imprisonment of ten years for persons with 1000 kilograms of marijuana or 1000 plants, and a mandatory minimum imprisonment of five years for persons with 500 kilograms or 500 plants. See 21 U.S.C. § 841(b)(1)(A) and (B).
. The amended version of 21 U.S.C. § 841(b)(1)(A), for example, reads simply:
(b) Penalties
... [A]ny person who violates subsection (a) of this subsection shall he sentenced as follows:
(1)(A) In the case of a violation of subsection (a) of this section involving—
(vii) 1000 kilograms or more of a mixture containing a detectable amount of marijuana, or 1,000 or more marijuana plants regardless of weight ... such person shall be sentenced to a term of imprisonment which may not be less than 10 years....
