L10 SAS - Sociedade Agrícola da Sobreira Lda (PT)










Essential oils production  for  local market. Growth without irrigation and wild picking. Myrtus Communis, Rosmarinus Officinallis, Lavandula Stoechas, Lavandula Pendunculata, Lavandula Viridis were selected. Specifically, the conservation fo Lavandula viridis is promoted, because of it  is  an endangered and rare species.


 Cereals and pasture improvement

 [2, 20]

Cereals (tritical, oat) grow without irrigation and improve nutrient content of soil. Minimum soil tillage has been carried out. Pasture is improved also by a  sustainable rotation grazing plan. 


 Fruits (arbutus trees)


Arbutus trees alone and interplanted with cerotonia siliqua (carob) and mirtus communis.  

 Fruits in mix between olives


Punica granatus and cydonia oblonga interplanted with already present olive trees.  


[13, 12]

Interplanted cork and cistus laudanifer already there with phyllirea, abrutus and retama sphaerocarpa. All planted species have mycorrizhae.  



Several nut trees were selected. Almond trees were interplanted with  Arbutus unedo and Quercus Suber. Carrob trees alone or interplanted with Quecus Ilex and aromatics (rosemary and myrtle). two areas were dedicated to pine and Piscatia lentiscus, respectively. 




 Test area


Non gmo seeds for pasture production were tested, as well as opuntia leaves as mulching material and nest (bed) technology as water aid. 


 Photo hunting


The idea is the creation of new observation points in the project areas.  



 Wildlife protection


The goal is to  grow back the natural vegetation/forest (by no human intervention), in which  wildlife will be protected (no hunting) and can breed. 




In these areas  native shrubs and trees species (Olea europaea (wild species),  Genista hirsuta, Juniperus spp , Phillyrea angustifolia /latifolia, Retama sphaerocarpa, Quercus suber/ faginea / coccifera /rotundifolia, Cytisus striatus, Rhamnus alaternus, Pistacia lentiscus)  were interplanted in a mix, in order to  protect soils and close the tree canopy again, and create the native forest (quercion fagineae alliance of evergreen oaks).


 Lake protection


Packaging of two exisisting lakes with with biodiversity promoting shrubs and trees (i.e. Phillyrea angustifolia, Crataegus monogyna, Salix salviifolia, Alnus gluinosa). To avoid erosion around ponds due to the wild animals, fences were installed, but left opening so that they can drink. Planting aquatic plants for filtration,soil fixation and food for fish.
New fish species (native) will be released in big lake and small photo observation post will be built. 


 Streambed protection


A strip of 2 rows of biodiversity promoting shrubs and trees (Morus alba, Crataegus monogyna) will be planted (or interplanted) on both sides of the small stream to guarantee longer water, less soil erosion.


 Biodiversity promoting plants


Increase plant biodiversity in protected areas to support insects, birds and mammals biodiversity.  



 Create employment


Optimization of working hours and organization.  

 Work with disabled people



 Provide social services


   N. Name  Comments   
   1 Seed collecting & native species    
   3 Existing vegetation

Partly done in some areas. landowner  create streets taking advantage of existing cistus to protect  from sun and wind.

  4 Mycorrhizae & plants

Plants inoculation with mycorrhizae was done in cork area.


 Full/half moon in all plants

   10 Soil ripping

 Only punctual interventions when indispensable. 

  11  Conservation Tillage

 Used for all areas, tilled and ploughed as little and as soft as possible. 

   14 Organic fertilizer

Self made worm compost food from the farm fresh food waste.

   23 Planting in mixes

 Used to implement biodiversity at all levels.

  26  Plant support Water aids study

The cocoons method and the opuntia leaves were  tested. 

   27 Watering/Drip irrigation

Watering  in beginning and drier months.

   29 Plant assist

Seedling protectors, mulching and stones. 

   31 Grafting trees

Almond grafted with olestro in nursery.

   34 IPM Plague control No IPM to date. Bird, bats, insects as natural solution.  
   43 Planting on ridges The Pistacia sp. and Prunus dulcis have been planted in ridges, the arbutus unedo were planted half way and the Ceratonia siliqua and Quercus suber in furrows.   
   44 Firewood 10% rule  Whenever possible, dead wood is  left to encorage bioversity.  
   52 Root protection.
