Stop Cutting the “Weeds”

By 2007, 20 years after the beginning of the eco-reforestation project, in some areas the trees had grown to a point where forest fires would cause relatively little damage.

Considering this, and seeing that the trees we had planted were still the only food sources for the many different insect pests that thrived in the dry season, Manual Víquez recommended that we “test” the suspension of our ground cover cutting practice. We had come to see this vegetation as weeds, with the negative connotations of that word.

¡Seed Dispersion

Evidently, some of the new saplings encountered in the project are germinating without our intervention.  By allowing the ground cover to grow, some of the trees we planted are now reproducing naturally.  Other species have been introduced naturally by animals or wind, demonstrating the natural process of seed dispersion.Readmore... »

The Importance of Soil Protection

In contrast to the grove of mangos just described, where fallen leaves were allowed to accumulate and form a “cushion” for the natural growth of other trees, in another grove of mangos on the same property, next to the small cabin built years ago, we have continued to rake and remove the fallen leaves, keeping the area “clean”. Not only has this area not seen the growth of other trees, but erosion has removed between 20 and 30 cm of topsoil, leaving the roots of the mango trees exposed.Readmore... »

Monitoring and Control of Vegetation Growth

We have not really been able to allow this additional vegetation to grow “freely”.  We have monitored it and intervened when necessary.

En 2011, we intervened to eliminate a large number of cornizuelo bushes (Acacia costaricensis) that were aggressively colonizing one area at the expense of the desired forest species, thanks to ants that nested in the cornizuelo and used this as a base to eliminate the other vegetation in the area.Readmore... »

Gradual Return of Wildlife

This new strategy of allowing secondary vegetation to grow naturally, along with the growth of the principal trees species and their production of fruit, has stimulated the migration of more and more diverse population of insects, birds, mammals, amphibians and reptiles into San Lorenzo.

Parakeets, parrots and urracas were the first to return to San Lorenzo, followed by thrushes, oropendola, woodpeckers, orioles, a variety of hummingbirds and birds of other species that animate the forest with their beautiful song.Readmore... »
