Other Environmental Initiatives

The CNFL has been developing activities aimed at environmental management since 1993. The processes have evolved and the company has expanded its environmental work at different levels and it is where working with external clients is key, to manage comprehensive management models of natural resources .

Currently working on two participation schemes, the first referred to a timely work on farms located in strategic points in rural areas, through the PAS Farms (Sustainable Environmental Practices) and the second under a more comprehensive scheme, which generates alliances between different actors social landscape, through interurban biological corridors.

PAS farms

Sustainable Environmental Practices (PAS) are implemented as a tool to direct their policies in favor of the improvement of water and soil resources, trying to strengthen social, economic, biotic and geophysical aspects through extension processes, aimed at productive units with the potential to develop sustainable forestry and agricultural projects, in the CNFL basins of interest (Rio Balsa, Rio Aranjuez, Rio Virilla), in common agreement with the owners of the farms.

Activities in Development

  • Inter-institutional work in conjunction with the Agricultural Extension Agency of the Ministry of Agriculture and Livestock (MAG), SENASA and Cantonal Agricultural Centers.
  • Advice for the establishment of Agroforestry Systems (SAF) and the design of biodigesters and bio-gardeners.

Biological corridors

Since the 2008 year, the CNFL has participated in the creation of a network of interurban biological corridors, where a space for the generation of ecosystem services is provided, favoring the quantity and quality of the water that reaches the reservoirs of the Hydroelectric Plants.

The CNFL has focused this component on a sector of the Greater Metropolitan Area, which corresponds to its served area, considering the following interurban biological corridors: 

  • Torres River
  • María Aguilar River
  • Tiribí River 
  • Para Tibás
  • Garcimuñoz 
  • Macho River 

The work in the interurban biological corridors generates positive effects on the environment and in turn allows the creation of strategic alliances with different public and private institutions, actively incorporating society in the processes of management and management of natural resources in the urban landscape .

The CNFL is a company that has developed experience in the field of nurseries over time, beginning its work in approximately 1992. From that moment to date, the company has directed the work of its nurseries based on its operations , mainly attending to the supply of trees to reforest watersheds of interest.

The main objective of the tree production in the nurseries of the CNFL, is to be an input in the processes of recovery and restoration of habitat, seeking to generate a direct effect in the improvement of the environment and in the generation of ecosystem services for society.

CNFL nurseries produce trees used in reforestation processes, ecological restoration and urban tree projects, as well as ornamental plants used in garden beautification processes and sale to third parties.

Currently two nurseries are established with the following characteristics:

Currently the production of these nurseries is placed in two sectors, where the first meets commitments associated with Corporate Social Responsibility (54%), the second to sales of trees and plants (36%), among others (10%). 

Initially the nurseries focused on the production of forest trees of several species, many with commercial potential, however, over the years, production has been diversified including native species of high ecological value, considering multiple use, to generate different benefits for the end user.

Since the 1993 year, in a visionary way, the CNFL invests in Environmental Education processes in educational centers, organized groups and municipalities.

The program is based on an environmental education approach different from traditional education, based on a pedagogy of action and action, in which the guiding principles of environmental education are the understanding of linkages (systemic approach) and need to consider the environment as a whole.

This environmental education program is called the Ecological Clubs Program and its objective is to implement, in educational centers in the watersheds of interest for the CNFL, environmental education processes, oriented towards a culture of environmental responsibility, with communal projection.

This program has two modules of environmental education, which bring together a series of workshops associated with four priority areas of education: socio-environmental, environmental challenges, water resources and energy.

Additionally, a series of didactic games associated with the same interactive workshops has been published to further empower educational centers in environmental education processes. The environmental education workshops are not only aimed at students, but also at teachers and administrators of educational centers, so that the education processes are consolidated from the base.

This program has worked in educational centers, both primary and secondary, from year 2005 to 2010 worked with 52 educational centers in the basin of the Virilla River, after this year other basins were incorporated such as Río Balsa, Río Aranjuez, Lake Cote, among others.

For the year 2017 worked in five educational centers: Fermín Rodríguez, Santa Rita, Pabellón, Brazil and Eleven de Abril, with an attention of approximately 110 students, 8 professors in the 7 activities programmed for the school year. The workshops developed are based on recreational activities that allow the student to learn and create awareness from the games and in this way generate more meaningful learning.

In addition, the CNFL has a space for environmental education, which is called: Finca de la Sostenibilidad y la Energía. Space in which a series of environmental practices are learned to conserve and protect the planet.

Trees and Shrubs for Use Book

Urban in the Central Valley, Costa Rica

Trees and Shrubs for Urban Use in the Central Valley, Costa Rica Book

In this book you will find described, in a clear and simple way, the characteristics of almost 100 species of trees and shrubs, as well as the best conditions and aspects to consider, to adequately establish these species in urban spaces. Thus, for example, you can know which ones produce flowers, which fruits are edible for fauna and what type, where they grow best, what dimensions they reach, among other details.

Due to its beautiful internal images and its simple design and writing, this book caters both to the needs of professionals in arboriculture and landscaping, as well as anyone who has a space available in their patio or garden and wants to make the best decision about which tree or shrub is the most suitable for planting; considering the space available, your personal preferences, the coloring of flowers, trunks, leaves and other characteristics of the tree, as well as the possibility of attracting birds, butterflies or other types of fauna.
