CL has a long tradition of pioneering and innovation in the agroforestry sector.


It is, of course, that it has been supporting several research projects related to its areas of activity, either actively participating in or financing, or just providing space and resources.

Under the Business & Biodiversity initiative, Companhia das Lezirias has established a commitment to the Institute of Nature Conservation and Biodiversity (INCB) for the development of various lines of applied research.

Mammalian diversity and abundance as a response to multi-use and management practices

Study of the mammalian species that occur, their abundance and dispersal in the Charneca da CL, as well as the factors that condition them, namely regarding management practices. Supports and monitors the establishment of ecological corridors between areas of higher abundance and no connection.

A high diversity of mammals has been observed, being associated with the presence of water lines and heterogeneous landscapes. The lower diversity and abundance indices are related to higher grazing intensities and simplified habitats. The installation of a living hedge is underway with a view to establishing an ecological corridor.

Rehabilitation of torrential regime water lines: contribution to the biodiversity of the coark oaks

Protection and restoration of vegetation in a torrential regime water line of about 7 km. Bird monitoring along protected waterline and witnesses. Interventions were carried out along 5.30 km of water line with regularization of the bed, laying of fence to protect the cattle and planting of willows, ash and dog rose.

TytoTagus Project: Barn Owl Postnatal Dispersion in the Tagus Valley

Study of the dispersal biology of owls that concentrate in large numbers during the summer in South Lezíria. 16 nest boxes were installed that presented average productivity of 2.2 flying juveniles/nest. These birds were ringed and some marked with transmitting radios, which allowed the general characterization of postnatal dispersal movements in terms of phenology, estuary approach patterns and relationship with the habitat.
