THE PASTURE RESOURCE According to MARA (1986),
the main forage sources in Morocco
were: i) natural pastures; ii) stubble and straw; iii) sown fodder; iv)
fallow; v) crop residues; vi) cereal grain; vii) industrial by-products.
Their respective estimated contribution to the forage budget was 28 percent;
38 percent, 10 percent, 6 percent, 2 percent, 7 percent and 8 percent.
However, it is important to make a few comments about these numbers: i)
the trend toward a decrease in the contribution of the natural pastures
over the years is due to their degradation, to the recurrent drought,
and to extension of crops on marginal lands which once were used as range;
ii) these numbers are averages over the entire country, reflecting the
importance of forage demand of cattle production systems and which are
met mostly by on farm production.
Small ruminants, on the other hand, rely more on natural
pasture (more than 70 percent in some regions); iii) these estimated averages
vary according to weather conditions in any given year. Thus, in a dry
year, relatively more resources are contributed by natural pasture (which
also results in increased grazing pressure and degradation) and grains
( which puts increased pressure on the economics and stability of the
farms, particularly the most vulnerable ones). During a wet year, important
sources include increased cereal yields), fallows, and grain ( due to
increased barley production and thus increased availability to animal
feeding).
Natural pasture and pastoral ecosystems
Natural grazing land, in varying degrees of productivity and use, extend
over some fifty three million hectares. Ten pastoral zones can be distinguished
according to topography, climate, vegetation and use (MARA, 1992). These
are: i) Zone 1: Eastern High Plateaux and the Moulouya Valley; ii) Zone
2: the Middle Atlas; iii) Zone 3: the High Atlas; iv) Zone 4: the Rif mountain
and its borders; v) Zone 5: the Mamora and Central Plateau; vi) Zone 6:
the plains and plateaux north of the Atlas mountains; vii) Zone 7: the Atlantic
coastal meseta; viii) Zone 8: the Argan tree area; ix) Zone 9: Presaharan
ecosystems; x) Zone 10: the Saharan ecosystems. Rangeland
ecosystems have been described and mapped for each zone (Berkat et
al. 1992). The number of such ecosystems (scale 1/ 2 500,000) is
29, 17, 13, 9, 5, 9, 1, 7, 12, 12, for the respective pastoral zones 1
to 10.

Ecosystems of the Eastern High Plateaux and
the Moulouya Valley
This zone extends over more than five million hectares. Thus, it is characterized
by a climatic gradient and a diversity in soil and vegetation resources,
even though the vegetation physionomic types are only a few: alfa steppes,
low shrub steppes, woodlands and shrublands. The bioclimatic gradient
extends from subhumid in the Debdou area in the North, to Saharan in the
South (Bou Arfa 160 mm) and in the Moulouya valley to the West (Outat
El Haj 157 mm). However, the largest proportion of the area is the arid
bioclimate with cold winters (200 to 350 mm of annual rainfall). Dominant
soils in the area are lithosols and regosols, but brown steppic and halomorphs
are also present. Livestock production is based primarily on sheep, and
secondarily on goats. Beef cattle have increased somewhat during the last
two decades, but are still of limited importance.
Major range ecosystems are:
i)forest stands of the sub-humid bioclimate composed of Quercus rotundifolia,
Juniperus oxycedrus, Stipa tenacissima, Rosmarinus officinalis. The
low herbaceous strata include Dactylis glomerata, Festuca ovina
and Koeleria vallesiana. This type covers about 140,000
hectares;
ii) woodlands of the semi-arid, composed of Callitris
articulata, Pistacia lentiscus, Stipa tenacissima, Rosmarinus officinalis,
Cistus villosus, Lavandula multifida, Dactylis glomerata, Artemisia herba-alba,
extending over some 200,000 hectares;
iii) halophytic steppes composed of Salsola foetida,
Atriplex halimus, Stipa capensis covering some 115,000 hectares;
iv) steppes of the arid bioclimate with cold winters,
in fair to deteriorated condition composed of Anabasis aphylla, Noaea
mucronata, Peganum harmala, Artemisia herba-alba, Stipa capensis, Frankenia
corymbosa, covering some 880,000 hectares;
v) steppes of the arid bioclimate with temperate winters,
in a fair condition, composed of Artemisia herba-alba, Frankenia corymbosa,
Noaea mucronata, Teucrium polium, Stipa capensis, Stipa parviflora.
This type covers some 290,000 hectares.
vi) steppes of the arid bioclimate with cold winters,
in fair to good condition, composed of Artemisia herba-alba, Stipa
parviflora, Stipa barbata, extending over some 190,000 hectares;
vii) steppes of the piedmonts composed of Stipa tenacissima,
Rosmarinus officinalis, Artemisia herba-alba, Thymus spp., Stipa
parviflora, Stipa barbata. This type covers some 330,000 hectares;
viii)) alfa (Stipa tenacissima) steppes on varying
soil types and substrates, and in varying ecological conditions, associated
with species such as Thymus sp., Noaea mucronata, Stipa parviflora,
Atractylis seratuloides, Schismus barbatus, Artemisia herba-alba, Lygeum
spartum. This type extends over 2,500,000 hectares. It provides an
important forage reserve, albeit of low quality, especially in this zone
characterized by long and severe drought events. It also provides invaluable
soil protection when not degraded. However, the recurrence of droughts,
along with maintaining too many animals by extensive use of concentrates
has recently led to a large scale degradation of this resource;
ix) degraded steppes of arid to Saharan bioclimate in
the middle Moulouya valley composed of Lycium intricatum, associated
according to local ecological conditions with Helianthemum spp.,
Halogeton alopecuroides, Salsola gemmascens, Noaea mucronata,
Atractylis serratuloides, Aristida spp., Hammada scoparia.
This type covers some 420,000 hectares.
The Middle Atlas
This zone has an estimated area of range extending over 1,230,000 hectares.
It is a mountain range in the centre of the country with a SW-NE direction.
Three subdivisions can be distinguished according to topography and climate:
1) the tabular Middle Atlas, with elevations from 1 000 to 1 900
metres, with high rainfall; 2) the rugged middle Atlas, ranging from the
semi-arid to the sub-humid; 3) the Khénifra area in the southwest, also
ranging from the semi-arid to the sub-humid. Livestock production in this
zone is based mostly on small ruminants.
Major ecosystems are:
i) woodlands of the piedmonts and temperate valleys which are composed
of Callitris articulata, Juniperus phoenicea, Pistacia lentiscus, Olea
europea, Phillyrea angustifolia. Species of the lower strata include
Globularia alypum, Rosmarinus officinalis, Stipa
tenacissima, S. parviflora. They extend over an estimated area of
185,000 hectares.
ii) forests of the semi-arid to subhumid zones with a
cold winter composed of Quercus rotundifolia, generally in dense
stands, but with openings having a herbaceous vegetation including Dactylis
glomerata, Bromus spp., Festuca spp., Cynosurus elegans.
They cover an area estimated at 340,000 hectares;
iii) forests of the humid zone with a cold winter, composed
of Quercus mirbeckei, Q. rotundifolia, Crataegus lacinita, Rosa sp.,
Cynosurus elegans, Dactylis glomerata, Arrhenatherum elatius. It extends
over a relatively limited area (6,000 hectares);
iv) forests of the subhumid and humid zones with a cold
winter, composed of Cedrus atlantica, Acer monspessulanum, Quercus
rotundifolia, and in the drier and colder parts Bupleurum spinosum
and Erinacea anthyllis. This type covers an area of 180,000 hectares;
v) forests of the sub-humid composed of Quercus suber,
Arbutus unedo, Cistus spp., Halimium halimifolium, Dactylis glomerata,
covering an area of approximately 15,000 hectares;
vi) low shrublands of the humid zone composed of Adenocarpus
boudyi, Genista pseudopilosa, Genista quadriflora, Festuca rubra, Hieracium
pseudopilosella, extending over some 18,000 hectares;
vii) mountain grasslands or turf, composed of Poa
bulbosa, Dactylis glomerata, Stipa lagascae, Festuca rubra, Festuca ovina,
Hieracium pseudopilosella, Scorzonera pygmea, Medicago suffruticosa,
covering some 50,000 hectares;
viii)) mountain shrublands composed of spiny xerophytes
such as Erinacea anthyllis, Cytisus purgans ssp. Balansae,
Alyssum spinosum, associated with herbaceous species such as Stipa
lagascae, Poa bulbosa, Festuca ovina, Festuca rubra, covering some
100,000 hectares.
The last three types are the most productive and also with
the highest herbaceous plant diversity. They are grazed mostly by transhumant
herds during June to October-November.
The High Atlas
This notable mountain range is composed of a series of longitudinal crests
with a SW-NE direction, between which are situated large depressions.
Highest points are at 4,165 m (Jebel Toubkal), 4,070 m (Mgoun), Tignousti
(3,819 m), Rhat (3,781 m), El Ayachi (3,700 m) and Azourki (3,677 m).
Valleys are generally of a NS direction. Annual rainfall ranges from 500
mm to 800 mm on the northern slopes, and from 200 to 600 mm on south facing
slopes, the driest part being the Southeastern part of the mountain. A
portion of rainfall comes in the form of snow (about 20 days above 3,200
m) and a sizable portion comes in the form of intense summer storms, representing
an important cause of erosion, and an important risk to agricultural land
in the valleys. Soils are relatively diversified but localised because
of steep slopes: rendzinas, brown forest soils, lithosols, regosols. However,
because of steep slopes, the dominant soils are lithosols. This, along
with a relatively high runoff and the nature of substrates (schists, marls),
makes the ecosystems of the mountain relatively dry, less diversified
than in the Middle Atlas for example. Further, as pastures, they are generally
less productive (owing to the previously mentioned constraints, and a
short growing season at altitudes above 1,800 m). Livestock production
is based on small ruminants, mostly goats on rangelands and forests, and
some cattle integrated to small farms on the terraces.
Major rangeland ecosystems are:
i) woodlands of the piedmonts and valleys, with temperate winters, composed
of Callitris articulata, Pistacia lentiscus, Ceratonia siliqua,
Olea europea, Lavandula multifida. Variations with Juniperus
phoenicea associated with Callitris articulata and Thymus
satureoides are also found. The area is estimated at 280,000 hectares;
ii) forests and woodlands at altitudes 1,400-1,800 metres,
semi-arid with temperate winters, composed of Quercus rotundifolia,
Juniperus phoenicea, Thymus spp., Globularia alypum, Dactylis glomerata,
and locally Callitris articulata. The type extends over an
approximate area of 370,000 hectares;
iii) woodlands of the subhumid and semiarid, with cold
winters, composed of Quercus rotundifolia, Pinus halepensis, or
Juniperus phoenicea, Globularia spp., Thymus spp., covering
an area over 160,000 hectares;
iv) forests and woodlands of the subhumid, with cold
winters, composed of Quercus rotundifolia, Cistus spp., Festuca
spp., Dactylis glomerata. The area covered is estimated at
320,000 hectares;
v) mountain grasslands of the high altitudes composed
of Festuca maroccana, F. rubra, Scorzonera pygmaea, Nardus stricta,
and Trifolium humile. This is a relatively productive ecosystem
which extends over 85,000 hectares;
vi) high altitude shrublands composed of Vella
mairei, Bupleurum spinosum, Alyssum spinosum, Festuca maroccana, Dactylis
glomerata, with locally Juniperus thurifera, covering approximately
770,000 hectares;
vii) high altitude low shrublands composed of Ormenis
scariosa, Adenocarpus anagyrifolius, Retama dasycarpa, Alyssum spinosum,
Bupleurum spinosum, Dactylis glomerata, Stipa nitens. The area concerned
is about 50,000 hectares
viii) high altitude steppes composed of Artemisia herba-alba,
Ormenis scariosa and Bupleurum spinosum and covering about
93,000 hectares
The last four ecosystems are used mostly by transhumant
herds from both sides of the High Atlas. Despite the relatively high animal
pressures exerted on them in the summer months and the appearance of degradation
indicators, these ecosystems remain relatively productive and with a good
species diversity.
The Rif mountains
This range extends all along the 400 kilometres of the Mediterranean coast
and some 100 kilometres inland, and covers, with its borders, approximately
916,000 hectares. The range is characterized by a topographic dissymmetry
represented by short and abrupt northern slopes (over 40 km only), and
a southern slope with altitudes decreasing progressively over long distances.
It is also characterized by a W-E decreasing climatic gradient (from over
1,200 mm to less than 300 mm). Three bioclimatic domains could be distinguished:
1) semi-arid in the coastal and sub-littoral areas, and also in its southern
and eastern borders; 2) humid in its central zone with altitudes exceeding
often 2,000 m; 3) sub-humid in the remaining areas. Soils include rendzinas
over marly and limestone substrates, luvisols/acrisols (rouges) over schists
and hard limestones, vertisols, and lithosols. However, due to high intensity
rainfall events, degradation of the vegetation cover (mostly through inappropriate
cropping on steep slopes), and the type of substrate, soil erosion is
a major problem with an average of 2,000 T/sq km/year. Livestock production
is based on small ruminants, mostly goats, in small-size herds.
Major rangeland ecosystems are:
i) tall shrublands (matorral) in semi-arid areas with temperate winters
(mostly along the Mediterranean coast, composed of Pistacia lentiscus,
Phillyrea angustifolia, Olea europea and locally Juniperus phoenicea,

and Kenitra to the west, to the Middle Atlas to the East and the Phosphate
plateau to the South. These plateaux are: 1) Mamora plateau between 30
m of elevation to 350 m; 2) the Central plateau between altitudes of 300
m to over 1000 m. The climate can be characterized by a number of gradients:
1) N-S: Kenitra 600 mm (sub-humid), Rabat 520 mm (sub-humid), Casablanca
440 mm (semi-arid); 2) W-E: Rabat 520 mm, Tiflet 450 mm (semi-arid); 3)
altitudinal gradient: Rabat (coastal city) 520 mm; Oulmès at 1260 m 784
mm (sub-humid). Soils resources include sandy soils, gleysols (hydromorphes),
vertisols, and lithosols. Livestock production is based mostly on sheep
and cattle.

vi) degraded steppes composed of Lycium intricatum,
Plantago ovata, Peganum harmala, Ferula communis, covering
some 96,000 hectares.
The Coastal Meseta
This zone is mostly cropland. However, the land closest to the Atlantic
ocean, or what is called the Sahel, over a width of 30 km, is in the form
of consolidated dunes with exposed limestone and dolomite on the surface
and so is mostly covered by natural vegetation used for grazing in autumn,
winter and early spring. Animals move to arable plains inland in summer
for stubble grazing.
Vegetation is basically composed of herbaceous species
such as Asphodelus microcarpus, Rumex bucephalophorus, Plantago coronopus,
Spergularia fimbriata, Lotus maroccanus, Vulpia myuros, Bromus rigidus
and Paronychia argentea. However, desirable perennials, including
woody species, may regenerate with protection from grazing: Chamaecytisus
albidus, Retama monosperma, Sanguisorba minor, Dactylis glomerata and
Piptatherum miliaceum.
The Argan zone
This zone extends over an estimated area of 1.5 million hectares. Consequently,
it is quite diverse in terms of physiographic and climatic conditions:
1) coastal plains of Abda and Chiadma; 2) the Essaouira region; 3) the
western area of the High Atlas; 4) the Souss plain; 5) the western Anti-Atlas.

Essaouira 278 mm, Agadir 250 mm, Anti-Atlas 200-250 mm; 2) increasing
with altitude in the western High Atlas; 3) decreasing from W to E in
the Souss plain south of the High Atlas. Soil resources are mostly lithosols.
Fluvisols are found in lowlands. Livestock production under rainfed conditions
is mainly goats on rangelands (particularly browsing on tops of the argan
tree). Under irrigated systems, cattle and sheep are dominant.

The Presaharan zone
This zone extends over 5.7 million hectares. It is bound by the 100 mm
and the 200 mm isohyets, respectively to the South and the North. As such,
it comprises the Southern slopes of both the High Atlas and the Anti-Atlas.
Major rangeland ecosystems are:
i) relatively degraded steppes of the arid bioclimate with cold winters,
composed of Artemisia herba-alba, Thymus spp., Anvillea radiata,
Launaea acanthoclada, Stipa parviflora. This type is nevertheless
relatively productive (about 400 kg DM/ha/year) and covers approximately
2,200,000 hectares;
ii) alfa steppes at their southern limit composed of
Stipa tenacissima, Stipa parviflora, Thymus spp., extending over
an estimated area of 300,000 hectares;

vii) degraded steppes of the Saharan bioclimate on regs,
composed of Zilla macroptera, Launaea arborescens, Hammada scoparia
and Farsetia spp. The estimated area is 750,000 hectares;
The Saharan zone
This zone extends over a considerable area of 46,500,000 hectares. However,
forage productivity is generally low and variable because of low and variable
rainfall (less than 100 mm). Nevertheless, the zone possesses a relatively
high ecosystem diversity due to the extensive area, and to spatial variability
(wadis, regs, hamadas, sebkhas, dunes). This diversity is at the base
of livestock activities, particularly camels adapted to make good use
of diversity over long distances.
Major rangeland ecosystems are:
i) steppes of the regs and hamadas, composed of Hammada scoparia, Aristida
spp. This is the most extensive type with over 34,500,000 million
hectares;
ii) steppes of the consolidated dunes, composed of Aristida
pungens, Calligonum comosum, covering about 2,600,000 million hectares;

Area 1,700,000 hectares;
viii) steppes of the rocky plateaux and mountains, composed
of Nucularia perrini, Traganum nudatum, Salsola spp. and
Hammada scoparia. Area 1,700,000 hectares.
Fallows, stubbles and crop residues
Fallow land. Each year, more than 2,000,000 hectares are under
fallow which is used for seasonal grazing. The flora is dominated by weedy
species and varies according to agro-climatic conditions: i) in the Southwest
(Souss), where precipitation is less than 250 mm and the temperatures
relatively warm, fallows are poor in terms of floristic composition and
productivity. Species include Stipa capensis, Medicago minima, Eryngium
tricuspidatum, Diplotaxis spp.; ii) in the Atlantic plains and plateaux
with less than 350 mm rainfall, and temperate winters, species include:
Malcolmia sp., Notoceras bicorne, Diplotaxis spp., Eryngium
sp., Medicago spp. iii) in the Atlantic plains and plateaux
with rainfall greater than 350 mm, Malva hispanica, Calendula bicolor,
Papaver sp., Sinapis sp., Avena sterilis, Medicago spp.,

Papaver sp, Trifolium spp., Hordeum murinum, Vicia sp.;
vi) in the Eastern Region: Bromus spp., Eruca vesicaria, Stipa
capensis, Medicago spp.
Stubbles. Stubbles are used from harvest (May-June)
to September-October. Their quality is relatively good during the first
four weeks (Kabbali and Berger 1990) due to a high grain content and a
high leaf/stem ratio. Later on, supplements are necessary, especially
for pregnant sheep and after September.
Crop residues and by-products. These include wheat
chaff, pelleted sugar beet meal, molasses, sunflower and cottonseed meal.
The quantities utilized in 1989 were 1, 138, 159, 185, and 48 KT, respectively
(Guessous 1991). In the recent past, increases in availability have been
greater for wheat chaff, and the sunflower and cottonseed meal.
Fodder Crops
Fodder crops are grown on approximately 386,000 hectares. This includes
annuals such as oats, fodder barley, berseem and fodder maize; lucerne
as a perennial.
Oats: or the oats/vetch mixture were grown in 1994
on approximately 70,000 ha and 50,000 ha, respectively (Amine and El Baghati
1997). Mixtures are used in Sais and pure oats in Khemisset, Tangiers,
Khenifra, Ifrane. The contribution of oats to the forage resource is 10
percent, corresponding to an average yield of only 1 500 FU /ha (MAMVA
1994-95): Fodder unit (FU) is defined as the equivalent to the net energy
content of 1 kg of standard barley grain.
Fodder Barley: occupies the second rank in fodder
acreage, after lucerne. It is cultivated on about 82,000 ha or 20% of
the fodder acreage and contributes 9 % to the total fodder units (FU)
produced by all sown fodder in the country (Amine and El Baghati 1997).It
is mixed with a legume, generally peas, on about one sixth of its area
(Ouknider 1997). Most fodder barley (90 percent) is gown under rainfed
conditions, particularly in the plains of Chaouia, Doukkala, Abda, Tadla,
and the Khemisset area (Amri and El Mzouri 1997). Under irrigation, it
is grown in the Tadla, Doukkala and Tafilalet perimeters. Yields are relatively
low on the average, attaining 1 500 FU/ha and 3,000 FU/ha, under rainfed
and irrigation, respectively (Amri and El Mzouri 1997).
Lucerne: it occupies the largest area of sown
fodder in the country, 85,000 hectares or about 22 percent (Birouk et
al. 1997). Owing to its high productivity, it contributes about 50 percent
of the total FU of the sown fodder. It is used as cut and carry fed fresh,
to make hay, silage, and pellets. Most of the lucerne is grown in three
major areas: i) the oasis systems of the valleys of Ziz, Draa and Dades
south of the Atlas mountains; ii) the terraces in the valleys of the Atlas
mountains; iii) the irrigated perimeters north of the Atlas, such as Tadla,
Doukkala, Haouz, Moulouya and Souss-Massa. Average yield is 53 t fu/ha
(Birouk et al. 1997).
Berseem: is grown on approximately 50,000 hectares
annually. The area continues to extend (20 percent increase in the last
decade) (Bounejmate 1997a). Its production attains 250 million FU (about
20 percent of the FU produced by sown fodder) (Bounejmate 1997a). Berseem
is grown mainly in the irrigated perimeters of the Rharb, Doukkala, Haouz,
and Tadla (Bounejmate 1997a). It is not grown in the southern perimeters
of the oases because of the cold, and lucerne is better adapted. Berseem
is grown under rainfed conditions in the Rharb and Loukkos plains and
in the North (Chefchaouen, Tetouan, Sidi Kacem). Average production attains
8 to 10 t DM/ha (Ameziane 1987), well below the potential of 16 tons DM/ha.
Fodder maize: is grown on approximately 15,000 hectares,
corresponding to 4 percent of the sown fodder (total maize acreage is
375,000 ha mostly for grain). It contributes some 116.6 million FU, corresponding
to 11.5 percent of the sown fodder production (MAMVA 1994-95). The major
areas of fodder maize under irrigation are the Rharb, Sous-Massa, Chefchaouen,
Tetouan, and Doukkala. Under rainfed conditions, it is mainly grown in
the northern parts of the country.
Forage Seed Production
Forage and pasture seed production is less developed compared to other
crops. This is due probably to the fact that forage seeds are considered
by all stakeholders and mainly by farmers as a by-product to forage production.
Therefore, most seeds are produced and distributed through the informal
sector.
The most important forage crops are Lucerne, berseem clover,
barley and maize under irrigation; oat, vetch, barley, ryegrass, fodder
peas, and annual medic in the rainfed zones. For range improvement plants
used are perennial grasses (Dactylis, Festuca, Agropyron, etc.),
annual medics, clovers and fodder shrubs (Atriplex, Acacia, and
native shrubs).
Although, efforts have been made to develop new forage
crop cultivars (Table 6), forage and pasture seed production
in the country is less developed compared to other crops.

In general, the assessment of forage and pasture seed needs
is very difficult due to the fluctuation of the amount of informal seed
used by farmers and to the lack of precise information related to the
subject. Table 7 gives areas cultivated with forage crops, seed requirement,
production and importation.
Seed production in the country is highly dependent on the
amount and the distribution of rainfall in the year. Therefore, seed needs
are covered either through national production or through imports. In
general seed import constitutes the rescue solution for forage and pasture
seeds particularly in dry years.
In Morocco forage
seed marketing and distribution are carried out by the National Society
for Seed Commercialisation (SONACOS). Some pasture seeds are also distributed
to range projects by the Pastoral Seed Production Centre (CPSP at El Jadida)
(Tazi, 1998).
It should be emphasised that Morocco
began range seed production during the nineteen-eighties. This is undertaken
by public institutions such as the Centre de Production des Semences Pastorales
at El Jadida and the Forestry Department. However the quantities produced
do not exceed 50 tons/year (Tazi, 1995). Range seed production is undertaken
for: (a) rehabilitation of degraded rangeland, (b) improvement of fallow
land, and (c) improving fodder crop production.
