Dehesas and pastureland: what you should know

This guide focuses on the livestock use of dehesas and pastureland, not on explaining what a dehesa is as a type of landscape or property in general terms — that definition is developed in the guide 'What is a dehesa' in this platform's property-types cluster. Here the focus is mainly on what it means, in practice, to manage the pasture of a property of this type when the goal is livestock activity.

Both dehesas and unwooded pastureland share a common feature from a livestock perspective: natural pasture forms the basis of livestock feeding for much of the year, which makes them particularly suited to extensive livestock farming models, covered in more detail in the guide 'Extensive or intensive livestock farming: what to consider when buying a property' in this same cluster.

Although they share this basis, a dehesa and pastureland are not synonyms: a dehesa is specifically characterised by combining pasture with scattered woodland, whereas pastureland may have no woodland at all, or only very sparse woodland. This difference, although it may seem purely scenic at first glance, has practical consequences for livestock management, as explained further on in this guide when discussing the role of woodland.

The terrain also varies between different properties of this type: some dehesas and pastureland sit on virtually flat land, while others have undulating areas or a certain gradient, which influences both how the pasture is used and how easy the livestock is to manage day to day. Very steep terrain can limit machinery access for pasture-maintenance tasks, an aspect worth assessing together with the rest of the property's characteristics.

Anyone looking for a property of this type is usually thinking in terms of long-term use rather than a quick solution: both the pasture and, where applicable, the woodland of a dehesa are resources that are managed and cared for over the years, and their condition at the time of purchase largely reflects how the property has been managed in the past. This long-term perspective is worth keeping in mind throughout the assessment of the property, rather than focusing only on the impression of a single visit.

Dehesas and pastureland can also be combined, on some properties, with other complementary land uses, such as small areas of cropland or distinct forested zones, adding a degree of diversity to the property as a whole. This combination of uses is not necessary for a property to have good livestock potential, but when it exists it is worth assessing as part of the whole, rather than analysing it in isolation from the rest of the property.

The pasture of a dehesa or pastureland does not yield the same amount all year round: it grows vigorously in periods of more humidity and moderate heat, and drops off notably in the driest or coldest months, depending on the area. This seasonality is one of the features that most shapes livestock management on this type of property, because it requires planning some way ahead for how the livestock will be fed during periods of lower pasture availability, whether through forage reserves, feed supplementation or adjusting the stocking rate.

The stocking rate — that is, how many animals the pasture of a property can sustainably support — depends on local factors such as soil type, rainfall patterns, pasture composition and the management applied over the years, so there is no general figure valid for any dehesa or pastureland. This guide does not offer indicative stocking-rate figures because they depend entirely on the specific case; a specialised technician can assess this on the ground.

In years of lower pasture availability — due to drought or other adverse weather conditions — the usual approach is to temporarily reduce the stocking rate, supplement feed with forage bought in from outside the property, or combine both measures, depending on the resources available and the owner's judgement. Having this management flexibility, rather than aiming to maintain the same stocking rate all year round, tends to be a feature of more sustainable long-term management.

The use of the pasture on a dehesa or pastureland does not always belong exclusively to the owner's own livestock: on some properties, the pasture is leased in whole or in part to third parties through some kind of agreement, which may coexist with or condition other uses of the property. It is worth clarifying this situation before buying, especially if your own project requires having the whole of the pasture available from the outset.

It is also worth bearing in mind that different types of livestock make use of pasture differently, which can influence the decision to combine more than one species on the same property over time — a practice that, on some dehesas and pastureland, helps make better use of the available vegetation. This guide does not assess which combination of species is appropriate in each case, because that depends on technical and market decisions specific to each project, but it is worth keeping in mind as one more management possibility, not an obligation.

It is also worth distinguishing the average annual stocking rate from the occasional peaks a property can support at a given moment: a pasture area may temporarily support somewhat more stock during the period of strongest pasture growth than it could sustain continuously throughout the year. Managing this difference well, adjusting the stocking rate through the seasons rather than keeping it fixed, tends to be part of careful long-term pasture management.

A common practice in managing dehesas and pastureland is to divide the property into different plots or paddocks and rotate grazing between them, letting each area rest for a period so the pasture can recover before being used again. This type of management helps keep the pasture in better condition over the long term than continuous grazing without rotation, although its specific application depends on each property and the technical guidance followed.

When assessing a property of this type, it is worth checking whether it is already divided into plots that facilitate this kind of management, or whether this would need to be created, which is directly related to the condition of the existing fencing — an aspect covered in more detail in the guide 'Fencing and basic infrastructure on livestock properties' in this cluster.

The number and size of the plots into which a property is divided affect management flexibility: a larger number of plots allows longer rest periods for each one, but also means more fencing to maintain and, generally, somewhat more complex day-to-day management. There is no optimal number of plots valid for every property, because it depends on the total area, the type of livestock and the management objectives; this guide simply notes that both extremes — a single undivided plot or excessive fragmentation — tend to have their own practical limitations.

The location of water points relative to the different plots is also part of pasture management: if each plot has its own access to water, rotation is easier to apply than if the livestock always has to travel to a single point, which can also concentrate wear on the pasture in the usual passage areas. This aspect connects with what is explained in the guide 'Water access for livestock: what to check before buying' in this same cluster, and it is worth assessing it together with the layout of the plots.

In the specific case of the dehesa, the scattered woodland (typically holm oaks or cork oaks, depending on the area) is not merely a scenic feature: it provides shade and shelter for livestock, contributes to soil fertility and, in some cases, generates an additional yield of its own from the trees that can complement livestock use. The condition and density of the woodland, as well as its management over time, influence the overall balance of the property between pasture and trees — a balance worth observing when assessing a specific dehesa.

Ageing woodland with little regeneration of young specimens can be a sign that this balance has been neglected over time, something worth bearing in mind when assessing the overall condition of the property, without this guide setting out specific technical criteria, which are a matter for a forestry or agronomic specialist.

The woodland of a dehesa may also require periodic management work, such as pruning aimed at maintaining its vigour and characteristic shape, which in some areas forms part of centuries-old management traditions. The state of this work on a specific property — whether it has been carried out regularly or has gone unattended for some time — tends to be reflected in the general appearance of the woodland, and it is worth observing it as one more indicator of the care the property as a whole has received.

On some dehesas, the woodland can generate its own yield, independent of livestock, related to the fruits or characteristic products of the species present, whose specific scale varies greatly from one property to another and cannot be quantified by this guide. When this yield exists, it is worth understanding it as an additional element to assess, without its presence or absence on its own determining the property's overall suitability for livestock.

The density of the woodland also affects how much pasture is available: very dense woodland reduces the light reaching the ground and, with it, pasture growth beneath the canopy, while more scattered woodland leaves more open ground for pasture. Neither situation is necessarily better in the abstract; what matters is whether the balance between woodland and pasture on a specific property fits the livestock project you have in mind.

Beyond the general aspects reviewed in any purchase of a livestock property (water, infrastructure, access, land suitability), on a dehesa or pastureland it is particularly worth checking the condition of the pasture at different times of year if it is possible to visit more than once, whether the land is already divided into plots for rotation, and, if there is woodland, its overall condition and density.

It is also reasonable to ask about the management that has been applied to the property so far — whether it has had continuous stocking, whether it has been left to rest at any point, whether the woodland has received any care — because historical management gives a more reliable picture of the property's real condition than a single visit. The general guide 'Buying a property for livestock use: overview' in this cluster covers the rest of the aspects to check in a purchase of this kind.

Where possible, it is worth cross-checking the information received from the seller against direct observation on the ground and, if the project warrants it, against the assessment of a specialised technician familiar with the particularities of dehesas and pastureland in the area. Conditions on a dehesa can vary considerably from one district to another within Spain, so local experience tends to provide a more accurate judgement than a generic assessment.

Finally, it is worth remembering that this guide focuses on the livestock use of dehesas and pastureland, and does not cover every aspect worth checking when buying a property of this type: the general guide 'Buying a property for livestock use: overview' and the guides dedicated to water, infrastructure and permits, all in this same cluster, complete a broader picture of what to check before buying.
