Opinion
Defendants appeal from judgment quieting plaintiffs’ title to Lake of the Pines lot 1407, rejecting defendants’ prescription and adverse possession claims to a portion of the lot. The parties stipulated to the facts and submitted the case to the judge without a jury. 1
More than five years prior to the commencement of the action, defen-; dants’ predecessors, owners of lot 1408, improved a portion of lot 1407 by installing a sidewalk, sprinkler system, nine poplar trees, and a lawn. The sidewalk was used for access to and from a deck and dock on the lake. A survey stake purporting to establish the boundary between the two lots had been erroneously placed on plaintiffs’ property withoút fault of either plaintiffs or defendants or their predecessors, and in making the above improvements and using them, defendants’ and their *321 predecessors relied upon the position of the stake. They believed that the improved portion of lot 1407 was part of their lot. 2
Each party and their predecessors were assessed taxes by lot number. No record exists of the sidewalk or ornamental plantings having been considered in the appraisal of the improvements on lot 1408. That lot has a home on it; lot 1407 is unimproved except for the sidewalk and plantings described above.
Finding that defendants and their predecessors mistakenly believed from the outset that the disputed portion of lot 1407 was part of lot 1408, the trial court determined that they did not intend to claim any land which did not belong to them and that their possession was not hostile and adverse. The court also concluded that they had not paid taxes on the disputed property.
Title to property by adverse possession may be established either under color of title or by claim of right. (Code Civ. Proc., §§ 322-325.) When, as in the instant case, title is asserted by claim of right, Code of Civil Procedure section 324 provides; “Where it appears that there has been an actual continued occupation of land, under a claim of title, exclusive of any other right, but not founded upon a written instrument, judgment or decree, the land so actually occupied, and no other, is deemed to have been held adversely.”
Section 325 of that code requires that to obtain title by adverse possession the land must be occupied and claimed for five years continuously and that claimants or their predecessors must have paid all taxes levied and assessed against the land.
The elements necessary to establish title by adverse possession are tax payment and open and notorious use or possession that is continuous and uninterrupted, hostile to the true owner and under a claim of title.
(Taormino
v.
Denny
(1970)
*322 A prescriptive easement requires establishment of the same elements except that payment of taxes is required only if the easement has been separately assessed. (Civ. Code, § 1007; Taormino v. Denny, supra, 1 Cal.3d. 679, 686.)
Although there is some conflict in cases from other jurisdictions, the rule is settled in California that the requisite hostile possession and claim of right may be established when the occupancy or use occurred through mistake. In

v.
Faris
(1895)
Woodward
v.
Faris, supra,
The relationship between the mistake rule and the exception was addressed in
Sorensen
v.
Costa
(1948)
Because under Sorensen adverse possession may be established by evidence that possession was based on mistake, it is apparent that rejection of the mistaken possession may not be based on speculation that the possessor might not have occupied the land had he known of the record title. Rather to show that the possession based on mistake was not hostile and adverse it must be established by substantial evidence that the possessor recognized the potential claim of the record owner and *324 expressly or impliedly reflected intent not to claim the occupied land if record title was in another. To hold that the occupier’s belief of ownership of the disputed land showed without more an intent not to claim nonowned land would emasculate the mistake rule.
Plaintiffs rely on
Berry
v.
Sbragia
(1978)
Plaintiffs urge that the adverse possession doctrine should be modified in the light of modern conditions. They state that the doctrine arose during a period when conveyances used metes and bounds descriptions, while the great majority of property is now described by reference to subdivision lots.
The viability of the adverse possession doctrine was questioned in
Finley
v.
Yuba County Water Dist.
(1979)
Such justification for the rule is as applicable to our modern society as in past years and has little relation to method of deed description. In *325 ascertaining the land described by map and parcel number, the landowner must still resort to metes and bounds description.
Plaintiffs also urge that the 1968 good-faith-improver legislation warrants modification of adverse possession doctrine because the legislation furnishes relief to the mistaken occupier. (Code Civ. Proc., § 871.1 et seq.) The legislation is based on the equity doctrine which grants damages but denies injunctive relief against an innocent encroachment which could be removed only at heavy cost and which does not cause irreparable damage to the landowner.
(Raab
v.
Casper
(1975)
In essence, the statutes authorize the court to permit the good faith improver to maintain his improvements on the land of the owner upon compensation of the owner protecting him from pecuniary loss, including attorneys fees in the proceeding and any loss relating to the owner’s prospective use of the property. (§ 871.5.) There are a number of limitations on such relief. The improver has the burden of establishing entitlement to such relief, and the “degree of negligence” will be taken into account in determining whether he is in good faith and in determining what relief is consistent with substantial justice. (§ 871.3.) A court may not grant relief if a setoff" or right of removal would accomplish substantial justice. (§ 871.4). In shaping relief, the court shall consider the owner’s future plans for use of the land and his need for the land. (§ 871.5.)
When enacting the good-faith-improver statutes, the Legislature did not repeal or substantially modify the statutes governing adverse possession. Thus, there is nothing to indicate a legislative intent that the good-faith-improver statutes were intended to supplant or modify the adverse possession doctrine. Unlike the adverse possession doctrine, the statutes are not predicated upon length of occupancy. Insofar as the statutory policy is predicated upon mistake by the occupant, they reflect an intent to grant relief to the mistaken occupier, not to repudiate or reduce his rights. While some of the equities reflected by the statutes no doubt underlie our rule protecting the mistaken adverse possession, the legislative recognition of those equities points to adherence to the mistake doctrine of

(3b) When it appears that the occupier enters the land mistakenly believing he is the owner, possession is adverse unless it is established by substantial evidence that he'recognized the potential claim of the record owner and expressly or impliedly reflected intent to claim the disputed land only if record title was determined in his favor. Any implication to the contrary in
Berry
v.
Sbragia, supra,
(5a) The stipulated facts in the instant case establish that defendants and their predecessors took possession of the disputed land mistakenly believing they were the owners. There are no additional facts expressly or impliedly showing that they recognized the potential claim of the record owners or that they intended to renounce their claim if they did not have record title. The trial court finding that they did not intend to claim any land that did not belong to them is not supported by the record. Under the stipulated facts, their possession was hostile and adverse.
The burden is on the adverse claimant of the fee to establish that no taxes were assessed against the land or that if assessed he paid them.
(Glatts
v.
Henson
(1948)
Similarly, where the claimant by construction of buildings or other valuable improvements or by the building of fences has visibly shown occupation of a disputed strip of land adjoining the boundary, several cases have reasoned that the “natural inference” is that the assessor did not base the assessment on the record boundary but valued the land and improvements visibly possessed by the parties.
(Price
v.
De Reyes
(1911)
Under the stipulated facts, we must uphold the trial court’s finding that defendants and their predecessors did not pay taxes on the disputed land. The parties and their predecessors were assessed taxes by lot number. There is no direct evidence that the sidewalk or ornamental plantings were considered in the assessment of the lots. There are no physical barriers, structures, or enclosures indicating that plaintiffs and their predecessors were excluded from using the sidewalk and planted areas on their land, or that the improvements were not a joint undertaking of the landowners. In the circumstances, the trial court was not required to infer that the assessor concluded the sidewalk and plantings reflected ownership of the disputed land by defendants and their predecessors.
As pointed out above, failure to pay taxes bars the claim of title by adverse possession. However, because no taxes were separately assessed, the lack of tax payment would not bar claim of prescriptive easement.
The parties have not briefed the questions whether a prescriptive easement for maintenance of landscaping would be the equivalent of a fee interest, whether such an interest may be obtained in the absence of tax payment (see
Raab
v.
Casper,
supra, 51 CalApp.3d 866, 876-877), and whether the size of trees or bushes should be limited to their smallest size during the prescriptive period (see
O’Banion
v.
Barba
(1948)
*328 The judgment is reversed.
Bird, C. J., Tobriner, J., Mosk, J., Richardson, J., Newman, J., and Kaus, J., concurred.
Notes
In the superior court, other parties were joined, but the prescription and adverse possession claims between plaintiffs and defendants were severed for trial. The other parties to the superior court proceedings are not parties to the appeal.
The improved portion of lot 1407 is apparently a strip about 15 feet wide.
Sorensen
v.
Costa, supra,
“Nor is there any merit to appellant’s contention that if adverse possession may be based on a mistaken entry, the period of the statute of limitations runs only from the discovery of the mistake.”
