In Spain there is a great diversity of protected natural spaces, from areas of wetlands to mountainous areas, and then deforested areas, which implies a great diversity of habitats and ecosystems.
The wetland areas, since Spain exist a great diversity, the variety of its origin, the numerous species that maintain and uses that they sustain. Approximately 1,500 are estimated in our country, characterized by a great abundance of small inland water bodies, accompanied by a small number of extensive and complex coastal aquatic systems.

It is estimated that 60% of the area of natural wetlands and lakes in Spain has disappeared, mainly in recent decades, with floodplains and inland freshwater wetlands being the most affected. The most important impacts of wetlands are related to very specific sectors: agriculture, urban development associated with tourism, industry and infrastructure. For this reason, Terra has collaborated in projects whose purpose is the conservation and recovery of these areas.

The IUCN considers an alien species when is established outside of its natural past or present distribution and invasive if provoques changes that threaten all native biological diversity (IUCN).

The invasive alien species (IAS) are currently recognized as one of the most important causes of biodiversity loss (second after the destruction of habitat), and may become the most important factor of ecological disintegration in the near future. In addition it will have important consequences in the economic development and the health sector, which are already beginning to be visible today.

Terra Naturalis works actively in the eradication of the main invasive species currently present in our country.

Environmental education is the key to understand the existing relationships between natural and social systems, as well as to get a clearer perception of the importance of socio-cultural factors in the genesis of environmental problems.

The environmental education has 3 main purposes:
  Ensure that both individuals and collectives understand the complex nature of the environment and the relationship between natural and social systems.
  Acquire the knowledge, values and practical skills
  Participate responsibly and effectively not only in the prevention and solution of problems but also the management of the natural environment.

Terra Naturalis has experience in carrying out technical and informative publications (guides, manuals, monographs ...) as well as in the design and development of environmental education activities and posters, panels and equipment for interpretation centers.

Geographic Information Technology (GIT) which grows expansion in recent years due to the versatility of its application in different areas, such as the environment, the natural resources, the conservation of threatened species and the planning and management of the territory, is used transversally in all Terra Naturalis' projects..

Some practical applications performed by Terra Naturalis with these tools are:
   Study and characterization about the habitat of threatened species by means of photo-interpretation of satellite images.
   Determination of the use of space, home range and seasonal movements of endangered species; prediction of potential distribution areas and ecological connectivity (Maxent, R).
   Prediction of potential distribution areas and ecological connectivity (Maxent, R).
   Network analysis for design and planning of itineraries in the field.
